Description

Title of the invention: Method for saving a parameter of a motor vehicle, associated device and vehicle.

[0001] The invention relates to motor vehicles and their use.

[0002] There is a need to make the use of motor vehicles more comfortable.

[0003] To this end, the invention relates to a method for saving a setting parameter of a motor vehicle comprising the following first steps implemented by an electronic device of the motor vehicle: - Receiving data from a first human-machine interface of the motor vehicle, then - Assignment (in other words: association) of a value to the setting parameter in volatile memory (for example, of the electronic device), based on the data, then - Saving (in other words: copying) the value of the setting parameter to non-volatile memory (for example, of the electronic device), - Shutdown of the electronic device, the shutdown resulting in a loss of the parameter value in volatile memory (for example, of the electronic device), (the shutdown occurring after the assignment step) then - Starting the electronic device (NB: startup takes place after the backup step), - Check if a predetermined duration (for example, stored in non-volatile memory, for example of the electronic device) has elapsed, then - Restoration to volatile memory (e.g., of the electronic device) of the value of the setting parameter, from non-volatile memory (e.g., of the electronic device) (In other words: copying, into volatile memory, of the value stored in non-volatile memory,) provided that the predetermined time has not elapsed (in other words: if the predetermined time has not elapsed).

[0004] Thanks to the invention, the driver of the motor vehicle does not need to re-enter the data when the vehicle has been stopped for a period less than or equal to the predetermined duration. The driver thus finds the vehicle in the state in which it was stopped, for example, after a few minutes of being stopped, which is particularly convenient for the driver. However, the data is not saved beyond the predetermined duration to guarantee the driver's privacy.

[0005] The first human-machine interface is, for example, a touch screen, a button, a joystick or a voice interface (implementing speech recognition).

[0006] The electronic device may include, for example, one or more microprocessors or microcontrollers.

[0007] The saving can take place following (in other words: be triggered by, or on) the assignment of the value or during the stopping of the electronic device (the saving of the parameter value can therefore take place during or before the stopping of the vehicle).

[0008] Alternatively, the backup can take place periodically.

[0009] The verification can take place during or after startup.

[0010] The data can be the value of the parameter or a value from which the electronic device obtains the value.

[0011] The shutdown of the electronic device may be a consequence of a reset or a power cut (in other words: switching off) of the electronic device (and the method according to the invention may include such a step).

[0012] The start-up of the electronic device can be a consequence of a reset or of an electrical power-up of the electronic device.

[0013] The shutdown of the electronic device can be triggered (for example, by the motor vehicle), following a locking or a switching off of the motor vehicle.

[0014] The start can be triggered (for example, by the motor vehicle), following an unlocking or switching on of the motor vehicle.

[0015] According to one embodiment, the predetermined duration is between 1 minute and 30 minutes.

[0016] Alternatively, the predetermined duration may be shorter or longer.

[0017] The duration can be measured from the shutdown or the save, for example.

[0018] The duration can be measured by a clock on the electronic device (or a external device).

[0019] According to one embodiment, the first steps further include the following steps (implemented after the assignment step): - Determining a component's command based on the parameter value, - Sending to the component of the order.

[0020] These two steps can be implemented, for example, before stopping and / or after starting.

[0021] Alternatively, the parameter value is read by the component.

[0022] For example, the component is an air conditioning unit in the passenger compartment of a motor vehicle (for example, a heater, an air conditioning unit, a ventilation device).

[0023] The parameter is in this case, for example, a setpoint temperature (in the case of a heating or air conditioning unit) or a fan speed (in the case of a heating, air conditioning or ventilation unit).

[0024] For example, the component is a second human-machine interface of the motor vehicle.

[0025] The second human-machine interface may be a screen and, for example, the parameter may identify a display on the screen, for example a vehicle guidance destination, an internet address or a movie.

[0026] The human-machine interface may be a sound playback device, and, for example, the parameter may identify a radio station or a sound recording.

[0027] According to one embodiment, the component is a (exterior) light of the motor vehicle (for example, a dipped beam, a position light, a main beam and / or a fog light), and, for example, the parameter can identify the on or off state of the light.

[0028] The invention also relates to a computer program comprising instructions, executable by a microprocessor or a microcontroller or a computer, to implement the steps of the process according to the invention, when executed by the microprocessor or the microcontroller or the computer.

[0029] The method according to the invention can be implemented by an electronic device. The invention therefore also relates to an electronic device configured to implement the steps of the method according to the invention, as well as a motor vehicle comprising the electronic device.

[0030] The characteristics and advantages of the computer program, the electronic device, and the vehicle are identical to those of the method according to the invention (without it being necessary to repeat them here).

[0031] When the electronic device, motor vehicle, or other element is "configured to" (or "capable of") performing or implementing a step or operation, this implies, for example, that the element includes means for performing the step or operation. These means preferably include electronic means, for example, a computer program, data in memory, specialized electronic circuits, wired or wireless connections, a microprocessor, and / or a microcontroller.

[0032] For example, the electronic device includes a computer program, a microprocessor and / or a microcontroller.

[0033] Other features and advantages of the present invention will become more apparent upon reading the following detailed description, which includes embodiments of the invention given by way of non-limiting examples and illustrated by the attached drawings, in which: - [Fig. 1] represents an electronic device and a motor vehicle according to one embodiment of the invention. - [Fig.2] represents an implementation of the process according to the invention, according to a example of realization, by the electronic device and the motor vehicle of [Fig.1].

[0034] In [Fig.1], certain elements are, of course, seen through transparency.

[0035] Detailed description of an example embodiment of the invention.

[0036] Figure 1 represents a motor vehicle 100 comprising, connected by a data bus 130 to an electronic device 110 (which may be one or more microprocessors), the following components: Traffic lights 141, 142, 143, 144, - Inside the passenger compartment of motor vehicle 100: - A 150-inch touchscreen, - A 120 heating appliance.

[0037] The remainder of the description of the example embodiment generally refers to Figures 1 and 2.

[0038] At step S00, while vehicle 100 is moving, the driver (not shown) of vehicle 100: - Operate lever 160 of motor vehicle 100 to turn on lights 141, 142, 143, 144, - Select a setpoint temperature of 20 degrees Celsius for heating 120 via the touchscreen 150, - Starts playing a video (not shown) on screen 150, - Launches a guidance system, with the destination being 19 Rue de la Pourvoierie in Versailles, via the touch screen 150.

[0039] At step S10, the electronic device 110 receives, via the data bus 130, data resulting from the interactions of the driver of the vehicle 100 with the touch screen 150 and the lever 160 at step S00.

[0040] At step S20, the electronic device 110 assigns the corresponding values ​​to the corresponding parameters in volatile memory 111 of the electronic device 110.

[0041] At step S30, the electronic device controls (after determining the corresponding commands from these values), via the data bus 130: - Lighting of lights 141, 142, 143, 144, - The heater 120 with a set temperature of 20 degrees Celsius. - Viewing the video on screen 150 by the video module 113 of the electronic device 110, - Guidance, with the destination 19 Rue de la Pourvoierie in Versailles, via the touch screen 150, by the guidance module 114 of the electronic device 110.

[0042] At step S40, the electronic device saves these parameter values ​​in non-volatile memory 112,

[0043] At step S50, the driver stops the vehicle, switches off the ignition, exits the vehicle, and activates the vehicle's door locks. The electronic device 110 then shuts down, for example, following a power outage. This results in the loss of parameter values ​​stored in volatile memory 111.

[0044] At step S60, 3 minutes after step S40, the driver unlocks the doors of the motor vehicle 100 and turns on the ignition of the motor vehicle 100. The electronic device 110 then starts, for example following a power-up.

[0045] At step S70, the electronic device 100 checks (using an internal clock) that no more than 10 minutes have elapsed since step S40.

[0046] As is indeed the case, at step S80, the electronic device restores the parameter values ​​to memory 111.

[0047] Step S90 is identical to step S30, the driver then finds the motor vehicle 100 in the state it was in when it was stopped at step S50.
