     2D DESCRIPTION Method and system for controlling an interior illumination of a vehicle 5 SUBJECT OF THE INVENTION This patent application has as its object a method for controlling an interior illumination of a vehicle according to claim 1 and a lighting system configured to implement the method for controlling an interior illumination of a vehicle according to the 10 claim 15, incorporating noteworthy innovations and advantages. BACKGROUND OF THE INVENTION 15 At present there is a need in the automobile sector to generate or compensate for a certain feeling in the driver through ambient lighting (position, color, intensity) taking as parameters physiological data of the same driver (pulsations, breathing, etc. . ) or specific driving situations. In particular, it is known from the state of the art, as reflected in document WO2006079475A1, a method and device for controlling an interior illumination of the motor vehicle, in which the device of the invention comprises lighting means for producing different lighting colors and intensities  The method of said invention consists in the automatic activation of a given lighting program selected from among a plurality of lighting programs according to the current state of a conductor. It is also known from the state of the art, as reflected in document JP2014094708A2, a lighting system to more simply detect a state of consciousness of an occupant, and also perform the lighting that conforms to the state of consciousness of the occupant, using interior lighting of a vehicle  Said cab lighting system includes an interior light on the roof of the vehicle, illuminating the periphery of the driver's seat. A vehicle driver has a wrist watch, which incorporates a sensor that measures the pulse of that driver. This signal is transmitted at 353 an indoor light control unit.  The control unit decides a state of awareness of the driver based on the pulse measurement value, and controls the attenuation of the interior light in such a way that the color of the lighting adjusts to the driver's preference, generating a state of comfort, generating, by way of example, a standing light when the driver is in an excited state. 5 Based on the aforementioned state of the art, it is emphasized that the control or management of the ambient light inside a vehicle is done by linking it only to information obtained from the driver of the vehicle, regardless of the state or needs of the other occupants of the vehicle. 10 Thus, it is seen that there is still a need for a method and a system to control an interior lighting of a vehicle, such that it personalizes the lighting properties for each of the passengers of said vehicle, depending on their respective mood . DESCRIPTION OF THE INVENTION The present invention consists of a method and a system for controlling interior lighting of a vehicle that starts from a common ambient light situation for all passengers of the vehicle.  The ambient lighting (for example intensity, color or position) is automatically changed for each occupant, and independently, depending on the mood and / or physiological state of each passenger. 25Currently the interior of the car lights up at the moment of ignition.  The driver can activate or deactivate a complete cabin lighting.  Adía today is not possible automatic activation depending on the mood and / or physiological state of the driver, and / or passengers, independently.  Thus, by way of example, if the driver has a low heart rate, or a state of sleepiness is detected, the vehicle would illuminate with blue ambient light to avoid the driver's sleepiness, according to Chromotherapy studies. However, since this point is beneficial for the driver, it can be for the rest of the occupants, who may wish to sleep but the blue light does not help them.  Note that the systems known today would illuminate the entire interior of the vehicle 354with light of the same color, that is, and following the previous example, blue color to avoid the state of drowsiness of the driver. Therefore the present invention provides a method that separates the ambient light for each of the occupants of the vehicle. In addition, there are driving modes of a vehicle, for example an autonomous mode, where the driver of a vehicle can disregard driving tasks, even not occupying the driving position.  In these cases, the ambient lighting requirements are very different from those of a typical current driving.  The method of the present invention is capable of adapting to said particular requirements and offering lighting according to each situation. 10 Cite in this regard known studies of Chromotherapy, according to which colors exert emotional influences on people, making it possible to generate, or accompany in an appropriate way, a mood. As an example, mention the situation in which it is detected that the pulsations of the conductor decrease below a certain threshold (which will be a particular one for each conductor), in which case a blue illumination (short wavelength) is chosen to avoid the segregation of melatonin, and prevent the driver from entering a state of sleepiness. 20 Thus, and more specifically, the invention consists of a method for controlling at least one vehicle lighting medium, comprising the steps of: i) determining a presence of a first occupant in at least one seat of the vehicle, ii) associating the at least one lighting means to the at least one square occupied by the first occupant based on the presence of the first occupant determined, 25iii) determining mood of the first occupant, and iv) controlling at least one light property emitted by the at least one lighting medium based on the mood of the first determined occupant. In this way, the present invention allows controlling the light property of the lights 30 arranged inside the passenger compartment according to the position occupied by the first occupant of the vehicle.  Thus, the first occupant can be: the driver in a normal driving; the driver in an autonomous driving; an occupant who is not a driver ... Depending on the position of the first occupant and his mood will be controlled, advantageously, at least one property light. 355In this regard, a passenger occupant is defined as a passenger who is at a certain time sitting in one of the seats of the vehicle.  The place of the vehicle means each of the approved spaces in a vehicle for transporting passengers, which coincide with each of the spaces authorized for them in the respective front and rear seats.  Presence sensor means the respective electronic devices that allow to determine if the vehicle seat is occupied or not by a passenger, including, without limitation, pressure or weight sensors in the seats, cameras, position sensors of a safety belt , etc… 10 Thus, the basic idea corresponds to a method with the steps of detecting a place occupied by a presence sensor, associating a lighting zone according to the position of the first occupant in the vehicle, detecting the rhythm of pulsations, or state of activity, of the first occupant, by means of a camera or other presence sensors, to associate the rhythm of pulsations, or state of activity, to a mood of the first occupant, to illuminate with a color, intensity, etc. . . , the lighting zone according to the position of the first occupant and according to its detected mood. The mood means the psychic state of the driver, which can be detected by a mood sensor. The method of the present invention establishes a relationship between the determined mood 20 for the first occupant detected and the ambient lighting most appropriate to the determined mood.  This relationship is based, as discussed above, in chromotherapy or other studies ... Thus, from objective information equivalent to a measure of the mood sensor, a probable mood of the first occupant is determined.  Depending on the position of the occupant, driving mode ... ambient lighting is established according to your needs. It is specified that the stage of detecting the at least one major occupant by at least one presence sensor, where the stage of associating the at least one illumination means is by means of at least one control unit, where the stage of detecting the The mood is by means of at least one mood sensor, and where the stage of controlling the at least one light property is by means of the at least one control unit. 6 According to another aspect of the invention, the step of controlling the at least one light property emitted by the at least one lighting medium comprises illuminating the at least one lighting medium associated with the square occupied by the first occupant with a first logic if the first occupant is detected in at least one previous square and with a second logic if the first occupant is detected in at least one subsequent square. 5 A rear or rear seat means any of the seats in the rear rows to the front two driver and co-driver. It is relevant, in the context of the present invention, to differentiate between a first occupant 10 detected in a previous square or a subsequent square.  The logic applied to the lighting of each of the zones depends on the position of the first occupant detected.  Thus, as mentioned above and by way of non-limiting example, a first logic is applied when the first occupant is the driver of a vehicle, pretending to contribute to the driver not falling asleep. On the other hand, a second logic is applied when the first occupant occupies a different position than the vehicle's driving, pretending to contribute, for example, to a state of relaxation, helping him to sleep.  More specifically, the first logic is based on the mood of the first occupant and a mode of driving the vehicle.  It is noted here that, when the first occupant 20 occupies the driving position, a first lighting logic of at least one lighting medium is applied.  This first logic evaluates the mood of the first occupant and the driving mode of the vehicle.  Thus, and by way of non-limiting example, if the vehicle circulates in a manual driving mode, it is of interest that the first occupant does not fall asleep while driving.  On the contrary, if the driving mode is completely autonomous, it is allowed to contribute, for example, to a state of relaxation, helping you to fall asleep. According to a preferred embodiment, the method of the present invention further comprises the steps of: 30v) determining a presence of at least one second occupant in at least one square of the vehicle, vi) decoupling at least one lighting medium associated with the at least one square occupied by the first occupant,7vii) associate the at least one lighting medium linked to the at least one square occupied by the at least one second occupant based on the presence of the at least one second occupant, vii) determine mood setting of the at least one second occupant, and vi) controlling at least one light property emitted by the at least one unlinked means of illumination based on the mood of the at least one second occupant, where the unlinked lighting means is associated with the square occupied by the at least a second occupant. Thus, in the presence of at least two passengers inside the vehicle10 (first occupant and at least one second occupant), the method of the present invention allows the interior lighting to be detached and adapted to the particular needs of each of them.  Each time a new passenger is determined inside the vehicle other than the first occupant, the previous method is executed.  Specify that, the step of untying at least one lighting means comprises maintaining at least one 15-lighting means associated with the first occupant.  Therefore, the totality of the lighting means associated with the at least one square occupied by the first occupant will not be unlinked, if this first occupant has not left the vehicle. In the event that the first occupant or the at least one second occupant leaves the vehicle, the at least one lighting means is associated with the at least one square occupied by another second occupant based on the presence of at least a second determined occupant. . On the other hand, the step of determining a presence of at least one second occupant at least one seat of the vehicle comprises determining a number of second occupants equal to or greater than zero.  Therefore, the method is executed regardless of whether or not there are 25 second occupants. On the other hand, the stage of the stage of associating the at least one lighting means detached from the at least one square occupied by the at least one second occupant comprises distributing the vehicle in at least one lighting zone, where the at least one lighting zone comprises at least one lighting medium, so that the at least one lighting medium associated with the at least one lighting zone emits at least one specific light property.  Thus there is always at least one lighting medium for each of the vehicle's lighting zones. 358It should be mentioned that distributing the vehicle in at least one lighting zone comprises establishing a first zone if the presence of the first occupant and / or of the at least one second occupant has been verified in the at least one previous place, so that the at least A lighting medium associated with the first zone comprises at least one light property based on the mood of a conductor. Thus, said first zone is established based on the presence of said occupant in the driver's seat.  Lighting means linked to the first zone are understood as those lighting means arranged in the front area of the vehicle.  The reason is that the driver's field of vision is very wide and he must constantly change his attention point.  Therefore, the lighting means that illuminate points of the previous zone or first zone, maintain a homogeneity of the emitted light properties. Specify that the front seats of the vehicle correspond to a single illuminated lighting zone with specific light properties depending on the mood of the driver. Advantageously, distributing the vehicle in at least one lighting zone comprises establishing at least a second zone if the presence of the first occupant and / or of the at least one second occupant has been verified in the at least one rear seat.  In this way the rear seats of the passenger compartment could have independent lighting, and detached from the first zone previously determined, in addition to the second zones being independent of each other. 20 The second zones have a second logic according to the companions, or passengers of the rear seats, different from the first logic that applies to the driver's seat. It can be said that, in the case of the rear seats, the function logic is the other way around than with the front seats.  By means of the same system and by way of example, the vehicle will illuminate the areas helping to generate a relaxed and pleasant atmosphere for the rear occupant, even lighting up the color zone that facilitates sleep, in case its occupants get close to that mood. In a preferred embodiment of the invention, the at least one second zone is associated with at least one rear occupant, so that each second zone comprises at least one light property based on the mood of the associated rear occupant. Thus, the rear seats of the vehicle correspond to a plurality of lighting zones that are illuminated independently depending on the mood of each of its occupants. 35According to an alternative embodiment of the invention, the step of dividing the vehicle into at least one lighting zone comprises establishing the at least one first zone and / or the at least one second zone manually.  In this way, the first and / or second occupant can choose the desired lighting conditions, according to their preferences. Advantageously, the at least one lighting zone comprises at least one lighting means, where the at least one lighting means is arranged adjacent to the at least one square with at least one first and / or second occupant detected. In this way it is possible to customize, and make independent, the lighting to each square, depending on the mood detected to its occupant.  Thus, when designing the interior lighting of the cabin, the lighting means are distributed to close areas around each occupant, with the distribution of zones depending on the number and position of the seats for the occupants of the vehicle. According to another aspect of the invention, the step of determining a mood state comprises measuring a heart rate of the first occupant and / or the at least one second occupant. In this way an objective biological parameter of the occupant is measured, which can lead to derive their mood, and / or activity and / or proximity to sleepiness. Alternatively, the step of determining a mood state comprises analyzing at least one facial expression of the first occupant and / or of the at least one second occupant.  In this way it becomes more reliable to determine the mood of said occupant. By facial expression is meant, by way of non-limiting example, a measurement of the movement and / or frequency of blinking of the eyes by means of a facial recognition camera. According to another aspect of the invention, the step of controlling the at least one light property emitted by the at least one lighting means comprises providing a intensity by means of the at least one lighting means.  Said light intensity is a complementary factor to the color of the light, with the aim of influencing the occupant mood of the vehicle with greater impact. In a preferred embodiment of the invention, the step of controlling the at least one light property emitted by the at least one lighting means comprises providing a color by means of the at least one lighting means.  Thus, and according to the influence of colors on people according to Chromotherapy studies, the lighting medium 3510provides a light of an appropriate color depending on the mood of the occupant at all times.  Note that, at any time, the present function of light emission in a given color can be deactivated, and the user can also customize its color, regardless of factors such as cardiac surithm. In this regard, mention that in a particular embodiment, the step of controlling the at least one light property is manual, that is, a manual operation.  In this way, the user has the possibility of controlling, according to his preferences, the light properties emitted by the lighting medium. In addition, the stage of determining mood setting is by means of a mood sensor, and where the method comprises an additional step of positioning the at least one mood sensor in the vehicle, in a position suitable for suffering, preferably close to the square. of the occupant of the vehicle. In this way, the control unit will be able to identify each mood sensor with each square occupied in the vehicle.  Note that the mood sensor can be a smart watch, a smart bracelet ... independent of the structure of the vehicle, and specific to each user.  Therefore, the control unit must be able to identify the position of each mood sensor in order to regulate the at least one light property of a certain area of the vehicle according to the needs of the user sitting in that area. According to another aspect of the invention, the step of positioning the at least one mood sensor comprises knowing a predetermined position of the at least one mood sensor in the vehicle, where the at least one mood sensor is comprised at least a seat and / or at least one seat belt.  These locations are known in advance and preferred due to their proximity to the occupant's body when sitting in the passenger compartment.  Said mood sensor can be, in an optional embodiment, a volumetric sensor. According to yet another aspect of the invention, when the at least one mood sensor is comprised in at least one smart watch or smartwatch, the vehicle comprises a first wireless signal transceiver and the at least one mood sensor comprises a second transceiver of wireless signals, where communicationBetween the control unit with the mood sensor is performed through said first and second wireless signal transceivers. The previous stage of associating each smart watch or smartwatch of each occupant with assumption is especially complex in a small environment, such as a passenger compartment of a vehicle, requiring a wireless signal transceiver in the smart watch or smartwatch, and another transceiver in the vehicle.  Said vehicle transceiver must be in a suitable position and known. Another option could be by triangulation within the vehicle of the second transceivers.  Another option would be a presence detection via GPS, or alternatively, manually introducing which person occupies each position.  The present invention also contemplates the embodiment of having a facial recognition camera as a mood sensor. According to yet another aspect of the invention, the first wireless signal transceiver is located in a position distant from the plurality of vehicle seats, for example in a passenger compartment corner.  Thus, by different intensities of the wireless signal the first transceiver can detect the positions of the occupants, positioning said second transceivers. Thus, and in a particular embodiment, the position of the first occupant and / or the at least one second occupant of the vehicle seats is determined by means of the wireless signal strength received by the first wireless signal transceiver of the vehicle. According to yet another aspect of the invention, the position of the first occupant and / or the at least one second occupant of the vehicle is determined by the time elapsed between the transmission and reception of the wireless signal, from the second wireless signal transceiver to The first wireless signal transceiver. According to yet another aspect of the invention, the vehicle comprises a graphic representation device through which the driver is shown the specific light properties corresponding to the at least one lighting zone of the rear seats of the vehicle. 12It is also an object of protection of the present invention a lighting system configured to implement the method for controlling at least one vehicle lighting medium, previously detailed, wherein the lighting system comprises: -at least one lighting means, -at least a presence sensor, 5-at least one mood sensor of at least one occupant, -at least one control unit, where the at least one control unit is in communication with the at least one presence sensor, the at at least one mood state sensor and the at least one lighting medium, where the stage of detecting the at least one occupant by means of at least one presence sensor, where the stage of associating the at least one lighting medium is by means of of the at least one control unit, where the stage of detecting the mood is by means of the at least one mood sensor, and where the stage of controlling the at least one light property is by He gave at least one control unit. 15The attached drawings show, by way of non-limiting example, a method and a system for controlling an interior lighting of a vehicle, constituted according to the invention.  Other features and advantages of said method and system for controlling an interior lighting of a vehicle, object of the present invention, will be apparent from the description of a preferred, but not exclusive, embodiment illustrated by way of non-limiting example in the accompanying drawings, in which: BRIEF DESCRIPTION OF THE DRAWINGS25 Figure 1. - It is a perspective view of the instrument panel of a vehicle comprising a graphic display device and the lighting system, in accordance with the present invention.

Figure 4D -It is a plan view of the vehicle with the four seats occupied, with a first illumination in the previous row according to the driver's mood, with a second illumination in the rear row and with a third illumination in the rear row, according to the present invention DESCRIPTION OF A PREFERRED EMBODIMENT15 In view of the aforementioned figures and, in accordance with the numbering adopted, an example of a preferred embodiment of the invention can be observed therein, which comprises the parts and elements indicated and described in detail below. . 20 Cite in this regard known studies of Chromotherapy, according to which colors exert emotional influences on people, making it possible to generate, or accompany in a suitable way, a mood. Thus, in figure 3 an example of recommended colors is observed to be able to alter or increase the moods of a person according to the colors of the environment.  25 As shown in Figure 3, if the first occupant 11 has a low heart rate or a drowsy state is detected, a blue illumination would help avoid the driver's drowsiness.  On the contrary, a yellow illumination could be beneficial to calm or temper an exalted mood, detected by a high heart rate. On the other hand, as shown in Figure 1 and Figure 2, the lighting system of the present invention comprises:14-at least one lighting means 7, which can be arranged in a panel of a door 13, in a dashboard or dashboard, in a console or between seats 12 ... -at least a presence sensor 41, which is arranged in a preferred embodiment in at least one seat 12 of the vehicle 1, - at least one mood sensor 42 that can be arranged in a safety belt 14 or can be arranged in a smart watch 61, - at least one control unit 3, where the at least one control unit 3 is in communication with the at least one presence sensor 41, the at least one mood sensor 42 and the at least one lighting means 7.10 Thus, the present invention is based on a method for controlling at least one lighting means 7 of a vehicle 1, comprising the steps of: i) determining a presence of a first occupant 11 in at least one square 2 of the vehicle 1, ii) associating the at least one lighting means 7 with the at least one 2nd place covered by the first occupant 11 based on the presence of the first occupant 11, iii) determine mood setting of the first occupant 11, and iv) control at least one light property 71 emitted by the at least one lighting means 7 based on the mood state of the First occupant 11 determined. 20 Therefore, a procedure capable of illuminating the interior of a vehicle 1 is sought, adapting to the needs of the first occupant 11 and its position inside the vehicle 1.  It is noted that it is not the same as that the first occupant 11 is sitting in a previous square 21 or in a subsequent square 22.  Thus there are different possibilities to differentiate: 25-If the first occupant 11 is sitting in the previous square 21, the interior of the vehicle is illuminated according to a first lighting logic, which will try to make the first occupant 11 not enter a state of drowsiness and, if you are nervous, help to calm him down. -On the contrary, if the first occupant 11 is sitting in the rear seat 3022, the interior of the vehicle 1 is illuminated according to a second lighting logic, which will attempt to contribute to a state of sleepiness detected in the first occupant 11. In addition, the first logic is based on the mood of the first occupant 11 and a driving mode of the vehicle1, differentiating whether the vehicle 1 is operating in manual driving mode or in autonomous driving mode.  In these cases, the method will adopt light properties according to the specific needs. 5 Thus, as seen in Figure 1, a presence sensor 41 disposed in the seat 12 determines the presence of a first occupant 11.  This first occupant 11 occupies the driver's seat 2.  Once the presence of the first occupant 11 in the previous square 21 of the driver is detected, the lighting medium 7 arranged in the driver's door 13 is associated with the square 2 occupied by the first occupant 11.  Additionally, the lighting medium 7 arranged in the passenger door 13 (not seen in Figure 1) is associated with the square 2 occupied by the first occupant 11.  Next, the mood of the first occupant 11 is determined by means of a mood sensor 42 disposed in the driver's seat belt 14.  Finally, at least one light property 71 of the lighting means 7 is controlled in order to adapt it to the mood of the first occupant 11 determined. Additionally, the present invention is based on a method that additionally comprises the steps of: v) determining a presence of at least one second occupant 15 at least one square 220 of the vehicle 1, vi) decoupling at least one lighting means 7 associated with the at least a square 2 occupied by the first occupant 11, vii) associating the at least one lighting medium 7 separated from the at least one square occupied by the at least one second occupant 15 based on the presence of the at least a second second occupant 15, viii ) determine mood setting of the at least one second occupant 15, and iv) control at least one light property 71 emitted by the at least one illumination means 7 separated based on the mood state of the at least one second occupant 15 determined, where the illumination means 7 disconnected It is associated with the square 2 30 occupied by the at least one second occupant 15. Thus, when a number of second occupants 15 equal to or greater than zero is determined, the method of the present invention helps to illuminate each lighting zone 23 of the vehicle 1 according to the specific needs of each passenger of the vehicle 1.  How has it been 35As seen above, each passenger comprises a differentiated mood and, depending on their position in the vehicle 1, the lighting must be different in order not to create counterproductive effects. Thus, as seen in Figures 1 and 2, the presence of a second occupant 15 in the front seat 21 of the passenger is determined by a presence sensor 41 arranged in the seat 12.  Then, the lighting means 7 disposed in the door 13 of the companion previously associated with the square 2 occupied by the first occupant 11 is disconnected.  Consequently, this illumination means 7 arranged in the passenger door 13 is associated with the second occupant 15, which occupies the front seat 21 10 of the passenger.  The mood of the second occupant 15 is determined by means of a smart watch 61 (not seen in Figure 1) acting as a mood state sensor 42.  The device knows that the smart watch 61 belongs to the second occupant 15 occupying the front seat 21 of the passenger since the second transceiver 52 exchanges information with the first transceiver 51 of the vehicle, which occupies a fixed position in the vehicle 1.  Specifically, the first transceiver 51 calculates the time it takes for a signal to travel between the first transceiver 51 and the second transceiver 52.  Finally, the lighting means 7 arranged in the passenger door 13 emits a light property 71 according to the needs of the second occupant 15.  It is noted that the lighting means 7 arranged in the door 13 of the driver continues to emit a light property 20 according to the needs of the first occupant 11. The stage of associating the at least one lighting means 7 with a square 2 occupied by the first occupant 11 or by the at least one second occupant 15, intends that the lighting means 7 arranged around the occupant understand a homogeneity of the 25 light properties 71 issued.  Thus, the occupant will be arranged substantially in the center and the lighting means 7 adjacent to said occupant will emit with the same color 711, intensity 712 and / or flicker frequency 713.  Thus, the at least one lighting means 7 associated with a first occupant 11 of the driving position is arranged, by way of orientation, on the door panel 13 on the driver's side, on the instrument panel, on the driver's side console, etc. The at least one lighting means 7 associated with a second occupant 15 of the passenger's seat is arranged, by way of guidance, on the panel of the door 13 on the passenger side, on the instrument panel, on the console on the passenger side, etc. 3517 Finally, the at least one lighting means 7 associated with a second occupant 15 of a rear seat22 is arranged, by way of example, on its door panel 13, at the rear of the seat 12 arranged immediately in front of the occupant, on the roof, etc. 5 Thus, by way of example, different user configurations are shown in Figures 4A, 4B, 4C and 4D, in order to better understand the operation of the present invention. Each lighting zone 23 has been schematically represented by a square.  In addition, each differentiated light property has been schematically represented by a grating of the differentiated square. As can be seen in Figure 4A, the four seats 2 of the vehicle 1 are occupied.  Therefore, there is a first occupant 11 in the driving position, a second occupant 15 in the front passenger seat 21, a second occupant 15 in the left rear seat 22 and a second occupant 15 in the right rear seat 22.  The present lighting situation could be carried out, for example, with a vehicle1 driven autonomously, where the lighting means 7 associated with the previous seats 21 may be illuminated with specific light properties 71 for each user.  The driver will be able to see in his field of vision indistinctly different light properties 71 and, because he must not take the controls of the vehicle, there is no problem of confusion created by differentiated light properties 71.  Thus, there will be four occupants in the vehicle and four different colors 711, associating each color 711 with the particular mood of each occupant and linking each mood to each square 252 of the vehicle1. As can be seen in Figure 4B, there is a first occupant 11 in the driving position and a second occupant 15 in the right rear seat 22.  The method of the present invention applies two differentiated lighting logics for each of the 30 occupants detected.  Thus, a first lighting logic will be used according to the mood detected for the first occupant 11 of the previous driving position 21.  Advantageously, the system will illuminate all the lighting means 7 according to the same specific light properties 71 according to the first occupant 11.  Thus, a first lighting zone 231 will be created that encompasses the entire anterior zone of18 vehicle 1, said first lighting zone 231 being illuminated with the same specific light properties 71. On the other hand, following Figure 4B, a second lighting logic will be used according to the mood detected for the second occupant 15 of the right rear square 522.  Advantageously, the system will illuminate the lighting means 7 associated with the second occupant 15 according to the same specific light properties 71 according to the second occupant 15.  A second lighting zone 232 will then be created that encompasses the entire rear area of the vehicle 1, said second lighting area 232 being illuminated with the same specific light properties 71. 10 According to a third example, as seen in Figure 4C, there is a single first occupant 11 in the vehicle 1, which occupies the previous driving position 21.  Therefore it is the driver of vehicle 1.  In order to harmonize the light properties 71 of the interior of the vehicle 1, it is advantageously illuminated with unique light properties 1571.  The appearance of a second occupant 15 would change the lighting and make it independent, according to the particular needs of each passenger of the vehicle 1. According to a fourth example, there is a first occupant 11 in the previous square 21 of the driver, a second occupant 15 in the previous square 21 of the passenger, a second occupant 15 in the rear square 22 right and a second occupant 15 in the rear square 22 left .  In this example it is assumed that the vehicle 1 is circulating in a manual driving mode.  Following the previous example, a first lighting logic will be used according to the mood detected for the first occupant 11 of the previous driving position 21.  Advantageously, then, a first lighting zone 231 will be created that encompasses the entire front area of the vehicle 1, said first lighting zone 231 being illuminated with the same specific light properties 71.  Regardless of whether there is a second occupant 15 disposed in the front passenger seat 21, the system of the present invention does not modify the lighting of said first zone 231.  As mentioned, the reason is that the lighting of the previous area of the vehicle 1 must be harmonized in order not to create ambiguities.  The field of vision used by the driver is very wide, and the entire first zone 231 of the vehicle 1 is illuminated with light properties 71 according to the mood of the first 35Occupant 11 or driver. According to the objective of the present invention, it makes no sense for the driver to look a little to the right, and see a color different from that of his area, even opposite according to the criteria established by Chromotherapy. Following the previous example, the second zone 232 is occupied for two seconds 5 occupants 15.  In this case, the second zone 232 is distributed in two independent lighting zones.  Each rear seat 22 comprises lighting means 7 that will illuminate according to the mood of the second specific occupant 15.  What is described in the present patent specification would also be applicable in the case of a seven-seater vehicle, that is, having several rear rows of occupants, in addition to the driver and the co-pilot. At any time, this function can be deactivated or the user can customize their color regardless of their heart rate. According to another aspect of the invention, as seen in Figures 4A, 4B, 4C and 4D, the step of associating the at least one lighting means 7 with at least one occupied square 2 comprises dividing the vehicle 1 into at least a lighting zone 23, where the at least one lighting zone 23 comprises at least one lighting means 7. 20 Thus, from the previous examples it is observed that for the rear seats, the same logic does not work as for the front seats: it has no logic that if the driver is sleeping but the second occupant 15u rear occupant 26 behind wants to sleep, his area will be illuminated A color that keeps you awake.  The logic is therefore reversed.  Thus, if it is detected if a second occupant 15 or subsequent occupant 26 with a descending heart rate is detected in the subsequent seats 22 with a descending heart rate, the illumination becomes a warm color (red, yellow), if it is intended to resuscitate the second occupant 15 or subsequent occupant 26, while with an ascending heart rate, the lighting becomes a cold color (blue, green), it is intended to reassure the occupant. 30In an alternative and optional embodiment, the driver is shown the color or type of lighting selected for the rear seats22.  In this way, the driver will see what color the rear seats are illuminating22, so he will know what his mood is for at least a second occupant 15 of at least one rear seat 22.  This 35The information can be represented on the screen or graphic display device 63, or through some illuminated area of the driver, through which you will see the illuminated color of each of the areas of the cabin.  Thus the driver can know the mood of the passengers in the rear seats22 without having to look back, or divert their attention from the road. According to another aspect of the invention, as seen in Figures 2 and 4A, the step of dividing the vehicle 1 into at least one lighting zone 23 comprises establishing the at least a first zone 231 and / or the at least a second Zone 232 manually. 10 According to a preferred embodiment of the invention, as seen in Figures 1 and 4A, the at least one lighting zone 23 comprises at least one lighting means 7, where the at least one lighting means 7 is arranged adjacent to the least one square 2 with at least one user 11 detected. It is sought to delimit lighting zones 23 around the passengers, in order to close lighting zones 23 with specific and unique illumination properties 71 for each passenger. More specifically, as can be seen in Figure 2, the step of determining a mood state comprises measuring a heart rate 421 and / or analyzing at least one facial expression 422 of the first occupant 11 and / or of the at least one second occupant 15. 20Concretely, the frequency of the heartbeat and / or the movement and / or frequency of blinking of the eyes is measured by means of a facial recognition camera 62. According to another aspect of the invention, as seen in Figures 1 and 3, the step of controlling the at least one light property 71 emitted by the at least one 25-illumination means 7 comprises providing an intensity 712, a color 711 or a flicker frequency 713 ... by means of the at least one lighting means 7. It is mentioned that the intensity 712, the color 711 or the flicker frequency 713 have been represented in the figures as different shading or grating of the lighting zones 23. 30 Preferably, the at least one lighting medium 7 is a multicolored LED.  And by way of illustrative example, and not limitation, the lighting means7 can be distributed in the following locations: For the driver, on the panel of a door 13, on the dashboard, and on the driver's side console, etc.  For the co-pilot, on his door panel, etc.  And for the rear seats, in its door panel, on the back of the seat 12 3521 arranged immediately in front, on the roof, etc.  The lighting means 7 can also be located as indirect light, on the door panel, on the feet and on the door trays. According to an alternative embodiment of the invention, the step of controlling the at least one light property 71 is manual. On the other hand, as seen in Figure 1, the method of the present invention comprises an additional step of positioning the at least one mood sensor 42 in the vehicle 1. According to another aspect of the invention, as can be seen in Figure 1, the step of positioning the at least one mood sensor 42 comprises knowing a predetermined position of the at least one mood sensor 42 in the vehicle 1, where the at least one mood sensor 42 is comprised in at least one seat 12 and / or in at least one safety belt 14. According to yet another aspect of the invention, each occupant wears a smart watch 61 or Smartwatch, which has the capability of measuring the occupant's heart rate, automatically changing, and depending on said heart rate, the lighting properties. 20 Said smart watch 61 for each user and outside the architecture of the vehicle 1 must be positioned and linked to each square 2 occupied.  Thus, as described above, there are different valid positioning alternatives, such as: triangulation of signals, recognition of signal intensities, recognition of signal travel times, by GPS ... 25 Details, shapes, dimensions and others accessory elements, as well as the components used in the implementation of the method and system to control an interior lighting of a vehicle may be conveniently replaced by others that are technically equivalent, and are not part of the essentiality of the invention or the scope defined by the claims They are included after the following list.
