    DESCRIPTION
    Selective signaling procedure of a starting system of a vehicle engine.
    The present invention relates to a method of selective signaling of a starting system of an engine of a vehicle, which allows the driver to be clearly signaled whether or not to operate an actuator to turn the engine on or off.
    Background of the invention
    Current vehicles may include new user functionality based on keyless starting. This function allows the user not to have to position the key in the cylinder enabled in the dashboard in order to activate the vehicle electronics or activate its propulsion system.
    With this new function, the start is produced by a vehicle sensor that detects the key in the vicinity of the driving area, inside the passenger compartment. Through this recognition, the vehicle is able to know that an enabled driver is in the driving position and enables the vehicle to start. Through the press of a start button, the ignition of the vehicle electronics occurs. By combining the pressing of this start button with the clutch pedal (in a vehicle with manual transmission) or the brake pedal (in a vehicle with automatic transmission), the vehicle's propulsion system starts up.
    It is also increasingly common for vehicles to include the system called "Start & Stop" (system that allows reducing consumption by turning off the engine in situations of stationary vehicle, such as traffic lights and holds), which provides a wide variety of cases in which the engine It is activated but does not perform any combustion (“idle” state).
    In addition, there are situations in which there is a voluntary deactivation of the engine in situations where vehicle driving safety is not guaranteed. All this great variability of situations induces uncertainty to the driver of the vehicle, causing him to be confused and not know if the vehicle is in a state of rest or, for example, has stalled it and must press the start button again to turn it on.

    It is known to use a light around the start button button that raises latency-shaped lighting only during the user's entry into the vehicle in order to capture their attention and, by means of the latency of the light surrounding the power button. start, show the need to press it to start the vehicle. Once the first start, the light does not provide more information to the user.
    Document US8111145 describes the use of a single switch to coordinate the operation of the ignition and the ignition system in a vehicle. This document describes the use of different colors to show the user the status of the vehicle, and to make it easier for him not to make mistakes such as pressing the start button a second time with the button already on. This system uses complex logic, so that each color indicates a different action to be performed by the driver. The association of each of the colors to the action to be performed is not intuitive, also introducing many variables and complications to the user. It is a non-obvious solution for the user that, in addition, does not include all possible cases.
    Therefore, the present invention aims to provide added value to the start button of a vehicle, allowing the user to know the state of the vehicle simply by looking at said start button.
    Description of the invention
    With the signaling process of the invention, the aforementioned drawbacks are resolved, presenting other advantages that will be described below.
    The present invention provides a method of selective signaling of a starting system of an engine of a vehicle, wherein the vehicle comprises at least one indicator light associated with a first vehicle starter actuator, comprising the steps of:
    - determine an engine status,
    - determine the presence of a driver in the vehicle,
    - illuminate the at least one indicator light based on the condition of the determined engine and the presence of the driver in the given vehicle, so that:
    if the state of the determined motor is off, the at least one indicator light is illuminated according to a first signaling mode,
    if the state of the determined motor is at rest and the presence of the driver in the
    5
    10
    fifteen

    35
    determined vehicle is negative, the at least one indicator light is illuminated according to a first signaling mode, and
    If the state of the determined engine is at rest and the presence of the driver in the given vehicle is positive, the at least one indicator light is illuminated according to a second signaling mode.
    In this way, the present invention aims at transmitting to the driver of the vehicle in a clear and unambiguous way the state of the engine of a vehicle with only two different signaling modes of the indicator light. Thus, the objective is to minimize the information transmitted to the driver by showing only in which cases the driver must proceed with a manual engine start in order to activate the engine propulsion and in which cases the engine is at rest and, therefore therefore, a new manual engine start is not necessary.
    Note that if the engine is running and burning, it is not a relevant state for the present selective signaling procedure of a vehicle engine starting system. In this state, the user must not start the engine and is aware at all times that the propulsion system is on. In this case and according to a preferred embodiment, when the state of the engine is on, the indicator light is illuminated according to the second signaling mode.
    According to a preferred embodiment, the first signaling mode of the at least one indicator light is an intermittent and the second signaling mode of the at least one indicator light is a permanent light. Thus, in cases where the user must proceed with a manual engine start in order to activate the engine propulsion, the indicator light activates the first signaling mode based on intermittent illumination. An intermittent illumination captures the attention of the user and, consequently, the driver will quickly understand that in order to activate the vehicle's propulsion system a press of the start button will be required. On the contrary, in cases where the engine is at rest and, therefore, a new manual engine start is not necessary, the indicator light activates the second signaling mode based on constant or permanent illumination. Permanent lighting does not attract the attention of the driver or claim their attention, so the user will understand that no action is required, since the propulsion system is activated and functioning properly.

    Alternatively, the second signaling mode of the at least one indicator light is an off light.
    Advantageously, the present invention aims to solve the cases that cause the driver the greatest error in relation to the state of the propulsion system. Thus, the state of the motor determined at rest is, for example, a state in which the Start & Stop system is active. Consequently, the engine does not perform any combustion but all its electronics are in operation. At the moment when the clutch pedal is pressed or the pressure on the brake pedal is transferred, depending on the type of vehicle gearbox, the engine will reactivate its combustion. It is noted that the start button must not be pressed in such cases. Even so, for safety reasons, there are situations in which it is necessary to turn off the engine of a vehicle, for example, when the presence of the determined driver is negative. For the driver, both states, at rest or off, seem the same since there is no combustion of the engine, even so, the action required of the driver if he wants to restart the gear, is totally opposite.
    An example of the above would be, for example, a voluntary detention of the vehicle by the driver. Because the speed of the vehicle is zero and a set of requirements not relevant to the present invention are met, the Start & Stop system is activated, the state of the engine goes to rest, ceasing the combustion of the engine but keeping its electronics active. In this case, the user must only press the clutch pedal or eliminate the pressure on the brake pedal, depending on the type of gearbox of the vehicle, and the engine will reactivate its combustion. On the contrary, if during this state of rest of the vehicle a presence of the negative driver is determined, the state of the motor passes idle has turned off. In this case, the user must press the indicator light and combine it with a press of the clutch pedal or eliminate the pressure on the brake pedal, depending on the type of gearbox of the vehicle, thereby reactivating engine combustion. The importance of notifying the driver of such cases is noted, because the feedback received by the driver of the vehicle without the existence of the selective signaling procedure of the present invention is the same in the different states of the idle or off engine.
    Preferably, an on and / or an off of the at least one indicator light is based on an on and / or an off of a plurality of indicators of a dashboard of the vehicle. For example, when the interior light of the vehicle is activated, also
    5
    10
    fifteen
    twenty
    25
    30
    35
    the indicator light illuminates. Likewise, when the interior light of the vehicle is deactivated, the indicator light goes out. In this way, the operating logic of the light indicator is linked to the existing logic of the plurality of indicators of an instrument panel. More specifically, the first lighting of the indicator light is linked to the first lighting of the courtesy light of the vehicle, once the user has unlocked the doors of the vehicle, and the switching off of the indicator light to the switching off of the courtesy light of the vehicle, Once the user has locked the doors of the vehicle.
    In addition, a light intensity of the first signaling mode of the at least one light indicator is advantageously greater than a light intensity of the second signaling mode of the at least one light signaling, and the light intensity of the second signaling mode of the at least A light indicator is substantially the same as the plurality of indicators on the instrument panel of the vehicle. In this way it is possible to emphasize the warning to the driver of the vehicle and capture their attention more easily by lighting the indicator light according to the first mode than its lighting according to the second mode.
    Additionally, these intensities can be regulated by means of corresponding regulators, predetermined as standard, alternatively independent and regulated by the user through the “infotenimiento” screen or of actuators specially enabled for it.
    In the signaling process according to the present invention, preferably, in a previous state of idle engine state and presence of the driver in the negative vehicle, if the presence of the driver in the given vehicle changes to positive or the first actuator of Vehicle start is activated, the at least one indicator light is illuminated according to the second signaling mode.
    Thus, for example, if the driver's detection goes from negative to positive, normal driving conditions are restored. The vehicle no longer detects an unsafe driving state, so the vehicle returns to a normal activated start / stop state. The illumination of the indicator light will, consequently, pass from a first signaling mode to a second signaling mode.
    Similarly, if the user voluntarily presses the engine start button, the engine turns on and the lighting becomes fixed. In this case, the driver assumes some
    5
    10
    fifteen
    twenty
    25
    30
    35
    unsafe driving conditions, so you voluntarily start the vehicle's engine. The illumination of the indicator light will, consequently, pass from a first signaling mode to a second signaling mode.
    According to a preferred embodiment, determining a driver's presence in the negative vehicle comprises determining an open vehicle driver's door and / or an unbuckled driver's belt. Although these signals are the most important, since they are the ones that show the intention of the user to leave the vehicle with greater clarity, alternatively a sensor can be used in the vehicle seat, a volumetric camera that detects presence inside the vehicle, etc. In these cases of unbuckled belt or open door, they are examples of unsafe driving, in which the vehicle does not voluntarily start the engine if it is not by an express order of the driver of said vehicle.
    On the contrary, determining a driver's presence in the positive vehicle comprises determining a door of a closed vehicle driver and / or buckled driver's belt, although sensors or cameras could also be used, as indicated above.
    According to a further embodiment, the vehicle could also comprise an additional light indicator associated with a second vehicle start actuator, so that the signaling procedure comprises an additional step of illuminating the additional light indicator according to a third lighting mode if the state of the determined engine is off or if the state of the determined engine is at rest and the presence of the driver in the given vehicle is negative.
    In this case, not only would there be one illuminated element, but, for example, the clutch pedal also illuminates to tell the user that he has to press it to start the vehicle. It is therefore understood that it is intended to inform the driver of the vehicle sequentially, indicating step by step the sequence of actuators that must be pressed at each moment in order to start the vehicle's engine.
    According to this additional embodiment, the step of illuminating the at least one indicator light according to a first signaling mode is initiated when the second vehicle starter actuator is operated. In this way, it is marked step by step what the user must do to start the engine, for example, first the clutch light is illuminated, the user

    The clutch operates, when the clutch has been pressed the indicator light illuminates to indicate that you must press the start button. Advantageously, prior to the actuation of the second actuator of the vehicle, the at least one indicator light is illuminated according to a second signaling mode.
    In addition, the signaling procedure may also comprise a step of turning off the additional indicator light when the second vehicle start actuator is operated.
    According to a preferred embodiment, the third signaling mode of the additional indicator light is an intermittent, the first vehicle start actuator is a keyless engine start switch and the second vehicle start actuator is a clutch pedal.
    The present invention aims to provide added value to the start button of a vehicle using it to show the driver the state of the engine. In addition, it intends to show the driver only the information that really matters to him:
    - If you must press the start button to start the engine (first signaling mode or intermittent lighting); or
    - If you do not have to press the start button, since the engine is already running (second signaling mode or fixed lighting).

    Description of a preferred embodiment
    Before starting the detailed description of the procedure according to the present invention, it is important to define what is meant as idle engine, engine off and draft engine.
    - Engine at rest: In this state the vehicle keeps the engine electronics on but turns off the engine combustion system. This mode is produced by the “Start & Stop” system when the vehicle is stopped at a traffic light, hold, etc.
    - Engine off: It is understood as engine off when the engine does not perform any combustion or its electronics are on. This state occurs when the user has voluntarily pressed the starter actuator with the engine running or resting. In addition, there are cases when the engine is shut down for safety. For example, a vehicle has entered sleep mode and in addition, the driver opens the door or unbuckles the belt. In these cases, for safety reasons, the vehicle turns off the engine completely and requests a new engine start (a new press on the start button).
    - Draft engine: It is understood as a stall engine when the engine has suddenly shut down due to a motor failure or a driving error, for example, because the user does not press the clutch pedal while the vehicle is stopped with the engine box gear changes. From now on and for the purposes of this description, when it is indicated that the engine is off, it is also included when the engine is open, since in both cases it is necessary to press the actuator again to start the engine.
    Additionally, it is understood that there is a state of engine 3 on, in which engine 3 has both the electronics on and the combustion system in operation. Note that it is not an exclusive combustion engine procedure, being able to be used equivalently in hybrid, electric or other alternative propulsion modes.
    As can be seen in Figure 1, the components of the vehicle involved in the process according to the present invention are the following:
    - Starter actuator 6, which is preferably the conventional start button of the
    5
    10
    fifteen
    twenty
    25
    30
    35
    vehicle, which is operated to turn on and off the engine 3 of the vehicle.
    - Light indicator 2 associated with said starter actuator 6, which is illuminated according to two signaling modes, as will be indicated below. This indicator light 2 is preferably arranged around the actuator 6, although it could be placed in any suitable position for the driver to see easily.
    - Sensor or occupancy sensors 4, which determine the presence of the driver. This sensor or sensors can be a driver's door opening sensor, a seat belt buckle sensor, a driver's seat presence sensor or a camera, among others.
    - Signals 5 of the vehicle dashboard, for example, buttons or actuators located on the dashboard or console of the vehicle, such as air conditioners, airbag switches, flashing lights ...
    - Second starter actuator 8, which can be, for example, the clutch or brake pedal of the vehicle, whose drive may optionally be required to start the engine 3.
    - Additional indicator light 7, associated with the second starter actuator 8, to indicate the need to operate said second actuator 8.
    Next, the signaling method according to the present invention is described with the aid of Figure 2:
    First (block 11), it is detected if an unlocking of vehicle doors occurs. Thus, in this evaluation it is analyzed if the user opens the vehicle (door unlock) by means of the remote control; or the user manually opens the door by inserting the key in the door cylinder to unlock the doors. In this situation, before the unlocking of doors the vehicle proceeds with the activation or ignition of part of the interior lighting of the vehicle.
    Therefore, as part of the interior lighting of the vehicle, in case of detecting said door unlocking, the present method activates the first signaling mode (block 12) of the light indicator 2, for example, intermittent lighting.

    25
    30
    35
    In block 13 it is evaluated when the engine 3 is on. In an initial state, the motor 3 is off and the indicator light 2 is illuminated according to a first lighting mode. Subsequently, the user can start the engine 3 by pressing the start button (actuator) 6, while pressing the clutch (manual transmission vehicle) or yielding the pressure on the brake pedal (automatic transmission vehicle), in if it is necessary to drive the second actuator 8. Thus, the state of the motor 3 turns on and the indicator light 2 is illuminated according to a second lighting mode. Alternatively, the driver may not press any pedal and press only the start button 6 so that only the vehicle electronics are activated without starting the engine 3. In this second case, because the engine is not running, the indicator light 2 is illuminated according to a first lighting mode.
    In block 14 it is determined if the motor is in a state of rest due to the activation of the "Start & Stop" system. In addition, said block 14 determines compliance with the activation conditions of the Start & Stop system. If the answer to block 14 is Yes, the indicator light 2 will be in the second signaling mode (block 18). In this way, the engine 3 will be in the idle state and the activation conditions of the Start & Stop system are satisfied, so a push of the start button 6 is not required to start the engine 3. On the contrary , if the answer to block 14 is No, the engine 3 will be in the idle state but the Start & Stop conditions are not properly satisfied, the indicator light 2 will be illuminated according to the first signaling mode. In this second case of block 14, while the engine 3 was in an idle state, some of the conditions that interrupt the operation of the "Start & stop" system have occurred, meaning that the engine 3 automatically goes into a stationary state. To proceed with a new start of the engine 3, the user must proceed with an additional manual start, so he must press the start button 6 again and, depending on the case, the clutch pedal or give pressure on the brake pedal .
    The reasons for the interruption of the operation of the “Start & Stop” system are the following:
    With the engine 3 in the idle state the driver removes the belt, which is detected by the sensor 4. In this case the engine 3 enters the stationary state. At this time, the driver is requested that if he wishes to start the engine 3 again without the belt anchored in the
    5
    10
    fifteen
    twenty
    25
    30
    35
    buckle, do it yourself by an additional press of the start button 6. It is done in this way for safety reasons, since there are very few circumstances that allow the user to drive without the belt. When the engine 3 is turned off, the indicator light 2 will be in the first signaling mode.
    When the belt is put on again, if the rest of the condition conditions of the engine 3 at rest are fulfilled, the indicator light 2 will be in the second signaling mode (fixed lighting).
    In the event that the user voluntarily presses the starter actuator 6, the motor 3 will change from idle state to off state (due to non-compliance with Start & Stop conditions) and already on (due to manual pressing of the starting actuator 6) . In parallel, the indicator light 2 changes from the second signaling mode, to the first signaling mode, ending again to the second signaling mode when the user has pressed the starter actuator 6.
    Similarly, with the engine 3 at rest, if the driver opens the door, which is detected by the sensor 4, the engine 3 evolves to the off state. The indicator light 2 will then be in the first signaling mode. When the door is closed again, if the conditions of the engine 3 at rest are met again, the indicator light 2 will be in the second signaling mode.
    In the event that the vehicle crashes with gear engaged, the engine shuts down and the indicator light 2 will evolve to the first signaling mode, indicating to the user that a new engine start is required.
    Therefore, it is observed that if in block 14 the answer is No, if the motor 3 is in standby mode and the conditions of the standby mode are broken for any of the indicated reasons, the light indicator 2 automatically switches to the First signaling mode (block 15). But if the user re-establishes all engine idle conditions (block 16) (for example, the belt had been removed and put it back on) the indicator light 2 will return to the second signaling mode.
    As mentioned, it is possible that even if the user does not meet all the conditions, for example he does not have the belt on, he decides that he wants to start the engine 3 of the vehicle. To do this, you can press the start button 6 (block 17) again, so
    that, being the driver responsible for the low safety conditions, the engine 3 starts again.
    In block 19 it is determined whether the driver has voluntarily stopped the engine 3. If yes, the indicator light 2 will be in the first signaling mode (block 20), and if not, the procedure will be repeated from the block 14.
    In block 21 it is determined whether the interior lighting of the vehicle is active. The light indicator 2 remains in the first signaling mode following the same parameters 10 as the general interior lighting of the vehicle. That is, after a certain waiting time or inactivity without the user performing manipulations or pressing buttons, the lighting system inside the vehicle will order the light emitters, including the light indicator 2, an order to turn off, thus improving battery consumption (block 22).

    Although reference has been made to a specific embodiment of the invention, it is apparent to one skilled in the art that the described signaling procedure is susceptible to numerous variations and modifications, and that all the mentioned details can be replaced by others technically equivalent, without departing from the scope of protection defined by the appended claims.
