    [0001] The present invention relates to the field of cleaning a vehicle interior and is more particularly aimed at a system and a method for cleaning the ambient air and the elements of the interior of said vehicle.
    [0002] In a known way, a motor vehicle makes it possible to move its users from one given place to another. A vehicle comprises a passenger compartment which is defined as the part of the vehicle reserved for users. This cabin includes various cabin elements to ensure user comfort and safety (seat, sun visor, etc.). During travel, the passenger compartment is soiled by various impurities such as the odors of sweat, cigarettes or food from its users, the odors of pets or even volatile organic compounds, known to those skilled in the trade under the abbreviation "VOC", such as polluting particles, dust or pollen from outside. All these impurities permeate both the ambient air of the passenger compartment and the elements of the passenger compartment and affect the comfort of vehicle users. This is particularly harmful for motor vehicles subject to a high occupancy rate, namely collective vehicles (buses, etc.) and shared vehicles (autonomous car, rental car, etc.).
    [0003] Currently, to clean the passenger compartment of a vehicle having a high occupancy rate, the vehicle is periodically moved to a cleaning station where the impurities in the passenger compartment are removed by means of an external cleaning device, such as a vacuum cleaner for example. This process has the disadvantage of being expensive since it requires, on the one hand, moving the vehicle to a station dedicated to cleaning and, on the other hand, labor to carry out the cleaning. In addition, such cleaning is complex to plan because the passenger compartment is not soiled in the same way depending on the frequency of use and the occupancy rate of the vehicle. However, if an early cleaning is a waste of time and money, a late cleaning can cause the dissatisfaction of the users of the vehicle.
    [0004] Known in the prior art, by patent application EP3278817A1, is a method for cleaning the passenger compartment of a vehicle subjected to a high occupancy rate which teaches to inject hot air combined with a disinfectant product into the enclosed vehicle compartment by means of a conduit from an external system. This process has the advantage of not requiring manpower to carry out the cleaning but does not solve the other drawbacks mentioned in the previous paragraph (necessary movement of the vehicle and complex planning of the cleaning). This process also has the disadvantage of evacuating only the impurities present in the air of the passenger compartment.
    [0005] Alternatively, patent application US2018/0126960A1 discloses a method for cleaning the passenger compartment of an autonomous vehicle in which said autonomous vehicle is moved to a cleaning station when unsanitary level sensors present in the cockpit indicate it. This process has the advantage of being able to precisely plan a cleaning of the vehicle but does not make it possible to solve the other drawbacks (necessary movement of the vehicle, use of labor to carry out the cleaning, etc.).
    [0006] There is therefore a need for a system and a method for cleaning the passenger compartment of a vehicle subject to a high occupancy rate, for example an autonomous vehicle, which is inexpensive, which can be carried out as soon as the state of cleanliness of said vehicle is not satisfactory and which effectively treats impurities.
    [0007] Although the invention was originally born for a motor vehicle, it applies more generally to any vehicle comprising a passenger compartment, in particular, a train, an airplane, a boat, etc.
    [0008] To this end, the invention relates to a vehicle comprising a passenger compartment and a passenger compartment cleaning system comprising at least one member for measuring the level of insalubrity N of said passenger compartment, at least one heating member configured to heat the air environment of the passenger compartment at a temperature above 40°C in order to desorb the impurities from the passenger compartment, at least one ventilation member configured to evacuate the ambient air and the desorbed impurities outside the passenger compartment and at least one control device configured to activate the heating device if the level of insalubrity N measured is greater than a predetermined maximum level of insalubrity N ET .
    [0009] The invention is remarkable in that the cleaning system is internal to the vehicle, which avoids moving the vehicle to a cleaning station, and makes it possible to purify the passenger compartment independently without manpower. This cleaning system is more effective, because being included in the passenger compartment, it is closer to the impurities to be treated. This position also advantageously facilitates the installation and maintenance of the cleaning system. This is particularly advantageous in the case of shared vehicles.
    [0010] According to one aspect of the invention, the heating member is configured to heat the ambient air of the passenger compartment to a temperature above 45°C, preferably above 50°C. Advantageously, the majority of the impurities present in the passenger compartment are desorbed at this temperature, i.e. they are extracted from the elements of the passenger compartment and pass into a vapor phase, which facilitates their extraction by ventilation.
    [0011] According to another aspect of the invention, the heating member is configured to heat the ambient air of the passenger compartment to a temperature below 80° C., so as not to damage the elements of said passenger compartment.
    [0012] Preferably, the vehicle comprises at least one cabin element comprising at least one heating member configured to heat the cabin element to a temperature above 40° C. in order to form a heated cabin element to desorb the impurities from the passenger compartment. Advantageously, the cleaning system makes it possible not only to clean the ambient air of the cabin but also the cabin elements, in order to eliminate the impurities captured from the cabin element and which are stored within it. .
    [0013] According to one aspect of the invention, the heating member is integrated into the cabin element, so as to be able to effectively clean said cabin element internally and not superficially. In addition, when the heater is integrated, the external appearance of the element is not modified, which is advantageous in terms of comfort and aesthetics.
    [0014] According to another aspect of the invention, the heating member is positioned on the surface of the cabin element, so as to be able to effectively clean the surface part of said cabin element, particularly exposed to sources of impurities. These two installation configurations advantageously allow optimal cleaning of the passenger compartment depending on the type of passenger compartment element.
    [0015] Preferably, the heating member is integrated or positioned on the surface of a cabin element comprising polyurethane foam or polyvinyl chloride or acrylonitrile butadiene styrene or polypropylene or polyethylene or polyester or a alloy of these thermoplastics, so as to improve heating and desorption. Preferably, the heating member is integrated into the volume of the cabin element.
    [0016] Preferably, at least one heated cabin element is a seat, in order to clean the impurities originating mainly from the clothing of the users, such as sweat.
    [0017] Preferably, the vehicle comprises a plurality of heated cabin elements for overall cleaning of the cabin.
    [0018] Preferably, at least one heated cabin element is the floor covering, in order to clean the impurities originating mainly from the shoes of the users, such as earth.
    [0019] Preferably, at least one heated passenger compartment element is the roof covering, in order to clean impurities such as VOCs and odors, cigarette smoke or food for example.
    [0020] Preferably, at least one heated cabin element is the coating of the side walls, in order to clean the impurities coming mainly from the users or even heavy toxic substances.
    [0021] Preferably, at least one heated cabin element is a sun visor, in order to clean impurities originating mainly from users, from the vehicle or from external pollution.
    [0022] Preferably, at least one heated passenger compartment element is the dashboard, in order to clean impurities originating mainly from users, from the vehicle or from external pollution.
    [0023] Preferably, at least one heated cabin element is the covering of a door, in order to clean impurities originating mainly from users, from the vehicle or from external pollution.
    [0024] Preferably, the heating member is in the form of a coil-shaped heating resistor. Preferably, the heating member is wired or wirelessly powered, for example, by induction. A heating member in such a form makes it possible to heat its vicinity homogeneously and efficiently and therefore to clean this vicinity globally and not partially. A wireless heater allows greater freedom of positioning in a cabin element which is then removable from said cabin.
    [0025] According to one aspect of the invention, the measuring device is in the form of a gas sensor, such as a metal oxide sensor, and raises the level of insalubrity N via the reading of the presence of toxic volatiles such as nitrogen dioxide N 1 and/or benzene toluene xylene N 2 and/or ozone N 3 and/or formaldehyde N 4 and/or any other volatile toxins, such as VOCs. This statement of a plurality of data N 1 -N 4 allows a reliable and objective measurement of the level of insalubrity N.
    [0026] Preferably, the predetermined maximum level of insalubrity N ET is obtained from databases on the maximum authorized presence of volatile toxins in the passenger compartment of the vehicle. Advantageously, the predetermined maximum level of insalubrity N ET is therefore a relevant means of comparison because it is based on the type of impurities found in the vehicle.
    [0027] Preferably, the power of the ventilation device is adapted to the level of insalubrity N and to the volume of the passenger compartment so as to quickly evacuate the impurities in suspension in the ambient air and to minimize energy consumption.
    [0028] According to one aspect of the invention, the vehicle comprises at least one electric charging device such as an electric battery, so that the measuring member, the control member, the heating member and the ventilation are electrically powered by a system internal to the vehicle, said electrical charging device operating independently of the on or off state of the vehicle.
    [0029] Preferably, the cleaning system comprises at least one filtering member configured to treat the desorbed impurities during their evacuation to the outside of the passenger compartment. Advantageously, this cleaning system does not release potentially harmful impurities into the atmosphere.
    [0030] Preferably, the filtering member is in the form of a mechanical filter, in particular a porous filter which absorbs and retains impurities, such as an activated carbon filter, or in the form of a chemical filter which destroys molecules of impurities, such as a filter by photocatalysis or by ozonolization, these two types of filter being effective for the types of impurities present in the passenger compartment.
    [0031] The invention also relates to a method for cleaning the passenger compartment of the vehicle of the invention, comprising: a step of measuring the level of unhealthiness N of the passenger compartment by means of the measuring member, a step of activating of the step of heating when the level of insalubrity measured N is greater than a predetermined maximum level of insalubrity N AND by means of the control member, a step of heating the passenger compartment in order to heat the ambient air of the passenger compartment and thus to desorb the impurities present by means of the heating member and a step of ventilating the passenger compartment in order to evacuate the ambient air and the impurities consumed outside the passenger compartment by means of the ventilation organ.
    [0032] Advantageously, this method makes it possible to clean the passenger compartment of a vehicle without moving it to a cleaning center, the entire cleaning system required to carry out the method being internal to the vehicle. Moreover, this process is autonomous so that it does not require manpower. In addition, this method makes it possible to detect the favorable moment to carry out the cleaning, avoiding unnecessary early cleaning and late cleaning which is a source of discontent for the occupants.
    [0033] Preferably, the heating step of this process is implemented for a duration adapted to the level of insalubrity N and to the volume of the passenger compartment so as to desorb the impurities and minimize energy consumption.
    [0034] Preferably, the duration of the heating step is adapted to desorb all the impurities while minimizing energy consumption.
    [0035] Preferably, during the activation step, the control member activates the heating step when there are no longer any users in the passenger compartment (NOP state), as a safety and comfort measure for the occupants (risk of discomfort, burns, bad smells, etc.)
    [0036] Preferably, the control member activates the heating stage when the passenger compartment is closed (CLOSED state), that is to say that the doors and the windows are closed, in order to improve the efficiency of the process.
    [0037] Preferably, the ventilation step is implemented until the level of insalubrity N is lower than the predetermined maximum level of insalubrity N ET . Advantageously, the ventilation step is optimized in terms of time and energy cost to evacuate the impurities.
    [0038] Preferably, the ventilation step is carried out once the heating step is complete, in order to avoid heat loss.
    [0039] According to one aspect of the invention, the method for cleaning the passenger compartment of the vehicle comprises a step of filtering the impurities consumed by means of the filtering member. Advantageously, this step avoids releasing potentially harmful impurities into the atmosphere.
    [0040] Preferably, the filtering step is implemented during the time-saving ventilation step.
    [0041] The invention will be better understood on reading the following description, given solely by way of example, and referring to the accompanying drawings given by way of non-limiting examples, in which identical references are given to similar objects. and on which:

    [0047] It should be noted that the figures expose the invention in detail to implement the invention, said figures can of course be used to better define the invention if necessary.
    [0048] Referring to Figures 1 to 5, there is shown schematically a system and a method for cleaning the passenger compartment of a motor vehicle V by internal heating according to one embodiment of the invention. As indicated above, although the invention was originally born for a motor vehicle, it applies more generally to any vehicle comprising a passenger compartment, in particular, a train, an airplane, a boat, etc.
    [0049] In known manner and as illustrated in Figures 1 and 2, a motor vehicle V comprises a passenger compartment 1 defined as the part of the vehicle V reserved for users, that is to say, the living space. The motor vehicle V comprises a plurality of doors 3 allowing users to get on and off the vehicle V, that is to say to access the passenger compartment 1, a plurality of windows 4 allowing a flow of air between the interior and exterior of the passenger compartment 1 and a trunk 6 defined as a storage space.
    [0050] In this example, the passenger compartment 1 comprises a plurality of seats 10, in particular, two front seats and a rear bench seat. The passenger compartment 1 further comprises various passenger compartment coverings to protect and dress the passenger compartment 1, in particular, a floor covering 11, a roof covering 12 and a side wall covering 13. Preferably, a covering 16 is also present on each door 3. Such coatings also make it possible to provide thermal and sound insulation in the passenger compartment 1.
    [0051] The passenger compartment 1 also comprises a plurality of sun visors 14 allowing users not to be dazzled in the event of strong external light, a dashboard 15 located at the front of the motor vehicle 1 accommodating various displays and actuators for controlling the multimedia, navigation, ventilation and the like. In this example, the motor vehicle V further comprises a storage space known as the “glove box”.
    [0052] In a known manner and as illustrated in FIGS. 1 and 2, the motor vehicle V comprises an electric battery 5 making it possible to generate electric current and thus supply the various electrical equipment of the vehicle V, namely the interior and exterior bulbs, the radio or again the electrical outlets as an example.
    [0053] According to the invention, the motor vehicle V comprises a cleaning system 2 configured to remove impurities from the motor vehicle V.
    [0054] Thanks to the cleaning system 2, the cleaning of the vehicle V is carried out internally, which does not require the vehicle to be moved to a cleaning center or an external device to be installed.
    [0055] Advantageously and as illustrated in Figures 1 and 2, the cleaning system 2 is integrated into the passenger compartment 1 in order to be as close as possible to the impurities to be cleaned. In addition, this facilitates the installation of the cleaning system 2 as well as its maintenance. Nevertheless, it goes without saying that part of the cleaning system 2 could not be included directly in the passenger compartment 1 but positioned at another place of the motor vehicle V, in particular, in a rear trunk or near the engine of the motor vehicle v.
    [0056] In this example, with reference to FIG. 3, the cleaning system 2 comprises a plurality of measuring members 20, a plurality of heating members 22, a filtering member 24, a ventilation member 23 and a control 21 whose structure and role are described successively below. In this example, the various components 20-24 are housed in the passenger compartment 1 and the various components 20-23 are electrically powered by the electric battery 5. It goes without saying that the components 20-23 could be powered differently.
    [0057] As illustrated in FIG. 3, the measurement devices 20 make it possible to measure a level of insalubrity N of the passenger compartment 1. Advantageously, these measurement devices 20 are in the form of gas sensors, such as sensors metal oxide by way of example, noting the presence of volatile toxins, which are nitrogen dioxide N 1, benzene toluene xylene N 2 , ozone N 3 and formaldehyde N 4 which makes it possible to determine a level of insalubrity N of the passenger compartment 1. It goes without saying that other types of sensors could be suitable, in particular, for detecting the presence of volatile toxins not mentioned, such as VOCs. Advantageously, the passenger compartment 1 comprises a plurality of measuring devices 20, which increases the reliability and accuracy of the measurement of the level of insalubrity N. Nevertheless, it goes without saying that the passenger compartment 1 could not contain a single measuring device 20. Furthermore, advantageously, the measuring devices 20 are located at the front of the passenger compartment 1 close to the position of the driver in order to measure the insalubrity felt by the driver. Preferably, with reference to Figure 1, the measuring devices 20 are distributed in the passenger compartment 1 in order to measure an average representative of the overall level of insalubrity and not a local level of insalubrity of an area of the cabin 1.
    [0058] According to the invention, the heaters 22 make it possible, in service, to produce heat, which is transmitted to the cabin elements 10-16 by conduction and to the ambient air by convection. The temperature in the passenger compartment 1 then increases, which has the effect of desorbing the impurities present, that is to say of extracting the impurities from the elements of the passenger compartment and passing them into a vapor phase.
    [0059] The heaters 22 are configured to heat the ambient air of the passenger compartment 1 to a temperature greater than 40° C., preferably greater than 45° C., more preferably 50° C., in order to desorb impurities from the cabin 1. Preferably, the heating temperature is less than 60° C. so as not to damage the cabin elements 1 as will be presented below.
    [0060] In this example, with reference to Figure 4, each heater 22 is in the form of a planar coil resistor. In other words, each heating member 22 comprises an alternation of rectilinear cylindrical tubes 220 and bent cylindrical tubes 221. Such a heating member 22 makes it possible to heat a given surface in a homogeneous manner. It goes without saying that the heaters 22 could have a different shape.
    [0061] According to one aspect of the invention, the heaters 22 are powered by wire or wireless, in particular, by induction. A wireless power supply advantageously makes it possible to make the cabin element removable from the cabin, for example, a floor mat. These two heating modes make it possible to effectively desorb the impurities. However, it goes without saying that another heating mode can be chosen.
    [0062] According to another aspect of the invention, the heating elements 22 can be rigid or flexible, the choice being based on their integration into the passenger compartment 1.
    [0063] According to one aspect of the invention, several cabin elements 10-16 are equipped with a heating member 22 to form a heated cabin element in order to cover the greatest possible volume of the cabin 1 subject to absorb impurities. It goes without saying, however, that only one or part of the cabin elements 10-16 can be equipped with a heating device 22, and in a complementary manner, that the same cabin element 10-16 can be equipped with a plurality of heaters 22. Cabin elements 10-16 not explicitly mentioned, for the sake of brevity and clarity, can also be equipped with one or more heaters 22. In addition, each member of heater 22 can be installed in two different ways depending on the convenience of installation and depending on the use of the cabin element 10-16, namely by insertion/integration into said element or lining said element on the surface. The association of a heating member 22 with a cabin element 10-16 is advantageous given that it makes it possible to heat the ambient air of the cabin 1 but also to heat the cabin element internally. passenger compartment 10-16 with which the heating member 22 is associated in order to thermally desorb the impurities contained in said passenger compartment element 10-16.
    [0064] By way of example, as illustrated in FIGS. 1 and 2, at least one heating element 22 is inserted in each seat 10, in each sun visor 14 as well as in the dashboard 15. Heating elements 22 line also the floor covering 11, the roof covering 12, the side walls 13 and the coverings 16 of the door 3. In this example, a large part of the cabin elements 10-16 is thus equipped with heating elements 22 and forms heated cabin elements. For the cabin elements 10-16 intended for comfort, for example a seat 10, it is preferable to integrate the heating element 22 into the seat 10 rather than to upholster it so as not to harm the comfort of the users. On the contrary, for the floor covering 11, the heater 2 can be placed on the surface to reduce the cost.
    [0065] In addition, in the example of the previous paragraph, the trunk 6 is lined with a heating device 22, although external to the passenger compartment 1, because nevertheless likely to be soiled by users in the same way as the elements cockpit 10-16. For example, the trunk 6 can be soiled by the luggage of the users, by leaks of liquids or by a pet.
    [0066] Furthermore, the heaters 22 are integrated into cabin elements 10-16 comprising polyurethane foam or polyvinyl chloride or acrylonitrile butadiene styrene or polypropylene or polyethylene or polyester or an alloy of these thermoplastics, so as to improve heating and desorption. It goes without saying, however, that the cabin elements 10-16 may comprise other materials.
    [0067] As indicated above, the heater 22 is configured to heat the ambient air of the passenger compartment 1 to a temperature above 40°C. In other words, the outside temperature of cabin element 10-16 is above 40°C. This differs from a conventional heated seat whose outside temperature is around 30°C and less than 40°C.
    [0068] The ventilation member 23 makes it possible to evacuate the ambient air and the impurities desorbed outside the passenger compartment 1. In this example, a single ventilation member 23 is shown but it goes without saying that a plurality ventilation members 23 could be used. Preferably, the ventilation member 23 is located at the level of the dashboard in order to take advantage of the existing ventilation ducts. Preferably, the ventilation member 23 is in the form of a mechanical fan.
    [0069] The filter member 24 makes it possible to treat, preferably mechanically or chemically, the desorbed impurities before they are evacuated outside the passenger compartment 1, for ecological reasons. Such a filter unit 24 is optional. Preferably, the filtering member 24 is associated with the ventilation member 23 in order to treat and evacuate the desorbed impurities simultaneously, but it goes without saying that the filtering member 24 and the ventilation member 23 can be distinct. Preferably, the filtering member 24 is in the form of a chemical filter which destroys the molecules of the impurities, for example a filter by ozonolize or by photocatalysis, or even in the form of a mechanical filter, for example a activated carbon filter. Preferably, the filtering member 24 is placed at the inlet of the ventilation member 23.
    [0070] The control member 21 is configured to activate the heating members 22 when the level of insalubrity N of the passenger compartment 1 is greater than a predetermined maximum level of insalubrity N ET , that is to say when the vehicle is in a dirty POK state. Advantageously, the maximum level of insalubrity N ET is determined from databases on the maximum authorized presence of volatile toxins in the passenger compartment 1 of the vehicle V, in order to adopt a scale of comparison that is as relevant as possible and adapted to the case of the vehicle V considered. However, the maximum level of insalubrity N ET can be determined differently. In this example, the control member 21 is in the form of an electronic computer electrically connected to the measuring members 20, to the heating members 22 and to the ventilation member 23 in order to control the cleaning steps.
    [0071] An example of the implementation of a method for cleaning the vehicle V according to the invention will now be presented.
    [0072] With reference to FIG. 5, the method for cleaning the passenger compartment 1 of the vehicle V comprises a step of measuring E 1 the level of insalubrity N of the passenger compartment 1 by means of the measuring devices 20, a step of activating E 2 , by the control member 21, heating members 22 in order to carry out a step of heating E 3 to a temperature greater than 40° C. when the level of insalubrity measured N is greater than a maximum level of insalubrity predetermined N AND .
    [0073] Preferably, during the measuring step E 1 , the measuring devices 20 note, at different times, the level of nitrogen dioxide N 1 , of benzene toluene xylene N 2 , of ozone N 3 and of formaldehyde N 4 in the passenger compartment 1 in order to define the level of insalubrity N of said passenger compartment 1. It goes without saying that the measuring devices 20 could measure other types of impurities such as VOCs. Preferably, the measurement step E 1 is implemented periodically or each time the motor vehicle V is inactivated.
    [0074] During the activation step E 2 , the control member 21 compares the level of insalubrity N measured in the passenger compartment 1 at different times with the predetermined maximum level of insalubrity N ET and makes it possible to determine with precision when to proceed. in the heating step E 3 . Thus, the heating step is activated when the passenger compartment 1 is considered to be in the dirty state POK, namely when the measured level of insalubrity N is greater than the predetermined maximum level of insalubrity N ET . When the measured level of insalubrity N is lower than the predetermined maximum level of insalubrity N ET , the passenger compartment 1 is considered to be in the proper state OK and no heating is carried out.
    [0075] According to one aspect of the invention, the heating step E 3 is activated only when the passenger compartment 1 is closed (CLOSED state). To this end, the heating system 2 comprises one or more closure sensors (not shown), positioned at the level of the doors 3 or the windows 4, in order to determine whether the passenger compartment 1 is closed. Preferably, the closure sensors are electrically connected to the control member 21.
    [0076] According to another aspect of the invention, the heating step E 3 is activated only in the absence of users (NOP state). To this end, the heating system 2 comprises one or more presence sensors (not shown), positioned in the passenger compartment 1, in order to determine whether users are present. Preferably, the presence sensors are electrically connected to the control member 21. The heating step E 3 thus allows effective treatment, that is to say without loss of heat and without inconvenience for the users of the vehicle. .
    [0077] The heating step E 3 is implemented by activating the heating elements 22 so that the ambient air is at a temperature above 40° C., preferably above 45° C., more preferably at 50° C. , in order to desorb all the impurities present and therefore to allow effective and non-partial cleaning. Preferably, the temperature of the heaters 22 does not exceed 60° C. in order not to alter the cabin elements 10-16. During this step, the heated cabin elements are therefore purified of their impurities by the heat given off by their heating member 22 transmitted by conduction. The ambient air is also purified by convection of the heat from the heated cabin elements. This process therefore makes it possible to advantageously purify the heated cabin elements and the ambient air of their impurities, that is to say the cabin 1 as a whole, which makes the process very effective.
    [0078] Preferably, the heating step E 3 is implemented for a duration adapted to the level of insalubrity N and to the volume of the passenger compartment 1 so as to desorb at least 70% of the impurities and to minimize the consumption of energy. Preferably, the duration is such that all the impurities are desorbed.
    [0079] Referring to Figure 5, the method includes a step E 3 ' of filtering the impurities consumed by the filtering member 24 and a step E 4 of ventilating the passenger compartment 1 by the ventilation member 23 in order to evacuate the ambient air and the impurities desorbed outside the passenger compartment 1 by means of the ventilation member 23.
    [0080] The filtering step E 3′ is implemented by treating the desorbed impurities in order to remove any harmful components from them. This step is not essential to the process for cleaning the passenger compartment 1 of the vehicle V but is carried out advantageously for ecological reasons in order to avoid the propagation of potentially harmful desorbed impurities in the atmosphere. This step is carried out once the heating step E 3 has been completed or simultaneously when the ventilation is carried out on a closed circuit.
    [0081] The ventilation step E 4 is implemented by turning on the ventilation member 23 until the level of insalubrity N of the passenger compartment 1 is lower than the predetermined maximum level of insalubrity N ET . Preferably, the ventilation unit 23 operates at a power adapted to the level of insalubrity N and to the volume of the passenger compartment so as to quickly evacuate the impurities suspended in the ambient air outside the passenger compartment 1 via the ventilation member 23, while minimizing energy consumption. According to one aspect of the invention, this ventilation step E 4 is carried out once the heating step E 3 has been completed in order to avoid heat loss and during the filtering step E 3′ , the desorbed impurities being treated in this way when being evacuated outside. However, it goes without saying that this ventilation step E 4 can be launched parallel to the heating step E 2 and after the filtering step E 3′ . Advantageously, this step is quick and easy to perform and uses means internal to the vehicle V.
    [0082] Preferably, in the absence of a filtering step E 3 , the windows 4 of the motor vehicle V are open during the ventilation step E 4 .
    [0083] Advantageously, this method makes it possible to determine with precision when to clean the passenger compartment 1, thus avoiding a waste of time and money linked to too early cleaning and the dissatisfaction of the users of the vehicle V linked to too much cleaning. late. This method also has the advantage of not requiring movement of the vehicle or labor to be carried out, being internal to the vehicle V, which makes it less expensive. Such a cleaning process is perfectly suited to a vehicle with a high occupancy rate.
