Description

Title of the invention: Control method for displaying the status of an acoustic vehicle alert system, associated device and motor vehicle.

[0001] The invention relates to a motor vehicle and the display by a screen of the motor vehicle. There exists, in particular, a need to facilitate access to relevant information via this screen.

[0002] For this purpose, the invention relates to a method for controlling a screen of a motor vehicle comprising an exterior (in other words: the motor vehicle comprising an exterior), the screen being a touch display screen (located in a passenger compartment of the motor vehicle), the control method comprising the following steps: • Obtaining (e.g., determining or receiving) an operating status of an acoustic vehicle alerting system (AVAS) of the motor vehicle, indicating whether the acoustic vehicle alerting system is in operation or out of operation, the acoustic vehicle alerting system being capable (when in operation) of emitting (i.e., emitting) a continuous sound, outside (i.e., towards the outside) of the motor vehicle, (i.e., or in addition, of warning pedestrians and cyclists of the presence of the motor vehicle) when a running speed of the motor vehicle is below a threshold (and is above 0 kilometers per hour, for example), then • (Sending a) Command to display a warning light on the screen, the warning light having: • A first appearance if the operating state indicates that the acoustic vehicle warning system is out of service (in other words: is not in operation or is not in operation), and / or • A second appearance, different from the first appearance, if the operating status indicates that the acoustic vehicle alert system is in operation (in other words: is in operation or in function), • Then, detection of a press on the indicator, • Then, upon detection of pressure on the indicator, (sending of a) command to display, on the screen, a window containing information.

[0003] Thus, by pressing the indicator, it is possible for the driver (or a passenger) to obtain information relating to the acoustic vehicle alert system, which is particularly simple, practical, and intuitive for the driver (or a passenger) of the motor vehicle.

[0004] The threshold is for example between 15 and 50 kilometers per hour (but can of course take other values). It is for example equal to 20 kilometers per hour.

[0005] The information may indicate a function of the acoustic vehicle alert system. For example, the information may indicate that the acoustic vehicle alert system warns pedestrians and cyclists of the presence of the motor vehicle, when a traveling speed of the vehicle is below a threshold, by emitting a continuous sound outside the vehicle.

[0006] It will be clear to those skilled in the art how to implement the step of obtaining the operating state of the acoustic vehicle alert system, and that this step can be implemented in various ways, without it being necessary to detail it here. The operating state is for example received or determined from received information.

[0007] For example, the operating state indicates that the acoustic vehicle alert system is out of service when the acoustic vehicle alert system is faulty or is disabled (e.g., the driver may, when the acoustic vehicle alert system allows, voluntarily disable the acoustic vehicle alert system).

[0008] For example, information (which in this case may be the operating state) indicating that the acoustic vehicle alert system has failed is received or information is received from which it is determined that the alert system has failed. This information or the information may be received from the acoustic vehicle alert system, a diagnostic circuit, or another component, after implementation (by the acoustic vehicle alert system, the diagnostic circuit, or the other component, in a manner known to those skilled in the art, of a diagnosis of the acoustic vehicle alert system (and the method may comprise this step or these steps of receiving and / or determining and / or diagnosing).

[0009] For example, the acoustic vehicle alert system may comprise a loudspeaker (or an electroacoustic transducer) capable of emitting the sound.

[0010] For example, the acoustic vehicle alert system may be diagnosed as out of service if it is detected that a road speed sensor of the motor vehicle has failed or if it is detected that the loudspeaker has failed.

[0011] For example, the sound has a sound intensity between 56 and 75 decibels.

[0012] According to one embodiment, the window comprises an element for setting (in other words or for example: a menu, a setting button, or a setting element) the acoustic vehicle alert system, for example, if the state indicates that the acoustic vehicle alert system is in operation.

[0013] According to one embodiment, the window comprises an element for configuring the threshold.

[0014] For example, the setting element is a slider that can be moved to adjust the threshold.

[0015] Alternatively, the sound has a sound intensity and the setting element is a sound intensity setting element.

[0016] For example, the motor vehicle comprises a driver's seat and a steering wheel, and the steering wheel is located between the driver's seat and the screen (other positions are well extended possible for the screen). The screen is for example in the passenger compartment of the vehicle.

[0017] According to one embodiment, the screen displays a travel speed of the motor vehicle, and / or a rotation speed of the propulsion engine of the motor vehicle.

[0018] For example, the witness comprises a speaker-shaped pattern.

[0019] For example, the witness includes an additional pattern when he has the first appearance than when it has the second appearance. This pattern can be text, for example indicating that the acoustic vehicle alert system is out of service.

[0020] For example, the witness appears brighter when it has the first appearance than when it has the second appearance.

[0021] According to a first variant or in combination, the witness appears in a first color when it has the first appearance, and in a second color, different from the first color, when it has the second appearance.

[0022] According to a second variant or in combination, the indicator appears flashing when it has the first appearance, and not flashing when it has the second appearance.

[0023] 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 method according to the invention, when it is executed by the microprocessor or the microcontroller or the computer.

[0024] The method according to the invention can be implemented by an electronic device (or a motor vehicle). The invention therefore also relates to an electronic device (or a motor vehicle) configured to implement the steps of the method according to the invention, as well as a motor vehicle comprising the electronic device.

[0025] 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).

[0026] When the electronic device, the motor vehicle, (or another element) is “configured to” (or “capable of”) performing or implementing a step or an operation, this implies, for example, that the element comprises means for performing the step or the operation. The means preferably comprise electronic means, for example, a computer program, data in memory, specialized electronic circuits, wired or wireless connections, a microprocessor and / or a microcontroller.

[0027] Other characteristics and advantages of the present invention will appear more clearly on reading the detailed description which follows, comprising embodiments of the invention given as non-limiting examples and illustrated by the appended drawings, in which: • [Fig.l] represents an electronic device and a motor vehicle, according to an embodiment of the invention, in top view, • [Fig.2], [Fig.3] represent what a motor vehicle screen displays [Fig.l] during steps of the method of [Fig.4]. • [Fig.4] represents an implementation of the method according to the invention, according to a exemplary embodiment, by the electronic device and the motor vehicle of [Fig.l].

[0028] In [Fig.l], certain elements are, of course, seen through transparency.

[0029] Detailed description of an exemplary embodiment of the invention, with reference to Figures 1 to 4.

[0030] [Fig.l] represents a motor vehicle 100. The motor vehicle 100 comprises a passenger compartment 120, a steering wheel 150 (located in the passenger compartment), a microprocessor 110 connected to a screen 140 of the motor vehicle 100 and to an audio system 130 comprising a loudspeaker 131.

[0031] The screen 140 is a touch screen located in the passenger compartment 120.

[0032] The audio system 130 complies with the standard known as “R138.01” for “AVAS”. The audio system 130, when in service, emits a continuous sound, outside 200 of the motor vehicle 100, when a traffic speed of the motor vehicle 100 is below a threshold, to warn pedestrians and cyclists of the presence of the motor vehicle 100.

[0033] With reference to [Fig.4], in step S00, the microprocessor 110 receives information indicating that the audio system 130 is in operation.

[0034] In step S10, the microprocessor 110 sends a command to display on the screen 140 a witness 153 comprising a loudspeaker-shaped pattern, as shown [Fig.2],

[0035] The screen 140 further displays, at the location 151 of the screen, a driving speed of the motor vehicle 100, and / or, at the location 152 of the screen, a rotation speed of the propulsion engine of the motor vehicle 100 (the display is for example controlled by the microprocessor 110).

[0036] In step S20, the microprocessor 110 detects a finger pressing on the indicator 153.

[0037] In step S30, the microprocessor 110 sends a display command to the screen 140 of a window 154, as shown [Fig.3].

[0038] Window 154 includes: • A cl slider that can be moved to adjust the threshold, and • The following text: “The AVAS of your vehicle warns pedestrians and cyclists of the presence of the motor vehicle when the vehicle's speed is less than 30 km / h", assuming that the threshold is set at 30 kilometers per hour.

[0039] According to a variant, in step S00, the microprocessor 110 receives information indicating that the audio system 130 is out of service.

[0040] Steps S10 to S30 then remain the same, except: • Witness 153' ([Fig.2]) which replaces witness 153, • Text displayed in window 154 which may display the reasons why the audio system 130 is out of service (e.g. received by the microcontroller 110 along with the status).
