Description

Title of the invention: Display method for parking assistance in a motor vehicle, associated device and vehicle.

[0001] The invention relates to a display method for parking assistance.

[0002] There is a need to facilitate the control of a parking aid for a motor vehicle by the driver of the motor vehicle.

[0003] For this purpose, the invention relates to a method for controlling (a) display on a first touch screen of a motor vehicle, the motor vehicle comprising an obstacle detection module (external to the vehicle), the method (being for example implemented in the motor vehicle and) being characterized in that it comprises the following steps: • Determining a service state of the obstacle detection module, the service state comprising a first piece of information and a second piece of information, then • Display command, on the first touch screen, of an icon comprising (a display of) the first information (in other words; of an icon, inside which the first information is displayed), then • Detection of a press on the icon (in other words: a contact) (for example: a finger) for a duration and, comparison of the duration with a first threshold and / or a second threshold, then: - If the duration is (for example, strictly) less than the first threshold, command to display, on the first touch screen, the second information, for example in a window of the first touch screen, - If the duration is greater than the second threshold, command to display, on the first touch screen, a menu for setting a parameter of the obstacle detection module.

[0004] The invention thus makes it possible, very easily, by a simple more or less long press, to display information (the second information) on the obstacle detection module or to configure the obstacle detection module.

[0005] According to one embodiment, the second threshold is higher (for example strictly) than the first threshold (and in this case, for example, the second information and the parameter setting menu cannot be displayed at the same time). Alternatively, the second threshold is lower (for example strictly) than the first threshold (and in this case, for example, the second information and the parameter setting menu can be displayed at the same time).

[0006] The method may comprise a step of controlling the closing of the menu. (respectively, from the window) upon detection of a press on the menu (respectively, on the window).

[0007] Determining the service status may include, for example: • A receipt of a message from the detection module (or, alternatively, from a remote server), the service status being determined from the message, and / or • A memory reading of data, the service status being determined from the data.

[0008] For example, the method may comprise a step of configuring the parameter of the obstacle detection module upon detection of an action (for example a press) in (or on) the parameter configuration menu of the parameter displayed by the touch screen.

[0009] Setting the parameter includes, for example, modifying the parameter.

[0010] The configuration of the detection module may include: • Sending an instruction to the obstacle detection module (or, alternatively, to a remote server), and / or • Writing data into memory.

[0011] The obstacle detection module comprises for example a microcontroller (or microprocessor) and (at least) one sensor (for example, located in the bumpers of the motor vehicle).

[0012] The sensor is preferably an ultrasonic sensor. Alternatively, it may be a laser sensor (for example of the so-called “LIDAR” type), or a camera. The detection module is for example capable of detecting an obstacle (outside the vehicle) and determining its position relative to the motor vehicle.

[0013] For example, the detection module has a detection range of less than 5 meters, for example less than 3 meters (and greater than 0 meters).

[0014] The obstacle detection module can thus be a parking assistance module.

[0015] The method may comprise the following steps: • Receiving an obstacle detection message from the obstacle detection module, the message including the position of the obstacle, • Control of a restitution (inside the vehicle passenger compartment) of the position of the obstacle, for example, by a screen (inside the vehicle passenger compartment) or by a loudspeaker (inside the vehicle passenger compartment).

[0016] According to one embodiment: • The first threshold is less than or equal to 600 milliseconds, and / or • The second threshold is greater than or equal to 600 milliseconds.

[0017] Alternatively, the first threshold and / or the second threshold may take other values.

[0018] According to one embodiment, the first information indicates whether the module of obstacle detection is in a disabled (or enabled) service state.

[0019] In this case, for example, the second information indicates a reason for the service status.

[0020] The reason for the service state may be, for example, a voluntary or involuntary (prior) deactivation of the obstacle detection module.

[0021] When the detection module is deactivated, the step of controlling a restitution is not implemented (in other words: it is inhibited).

[0022] According to an exemplary embodiment; • The first information may indicate that the detection module is partially deactivated (at the rear of the vehicle), and • The second information may indicate (that it is because or) that a trailer is attached to the motor vehicle.

[0023] According to one embodiment, the first information indicates an operating anomaly of the obstacle detection module. The first information may, in this case, for example, be displayed upon detection of the first vehicle shifting into reverse gear, for example, for 10 seconds.

[0024] In this case, the second information may indicate an action to be carried out to remedy the operating anomaly (and the method may comprise the implementation of this action), for example cleaning a sensor of the detection module.

[0025] According to one embodiment, the parameter is one (at least) of: • An activation or deactivation state of the obstacle detection module, • A sensitivity of the obstacle detection module (for example, its range), • The amplitude of a sound restoring a location of obstacles (for example, a pulse increasing in frequency when the obstacle is closer to the vehicle) detected by the obstacle detection module.

[0026] Alternatively, other first information, second information or parameters are conceivable.

[0027] 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.

[0028] 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.

[0029] 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).

[0030] 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 comprises means for performing the step or 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.

[0031] For example, the electronic device comprises a computer program, a microprocessor and / or a microcontroller.

[0032] 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, • [Fig.2], [Fig.3] and [Fig.4] represent the display of a vehicle screen of the [Fig.l] at various stages of the process of [Fig.5], • [Fig.5] 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].

[0033] In [Fig.l], certain elements are, of course, seen through transparency.

[0034] Detailed description of an exemplary embodiment of the invention, with reference to Figures 1 to 5.

[0035] [Fig.l] represents a motor vehicle 100. The motor vehicle 100 comprises a microprocessor 110. The microprocessor 110 is connected to the following elements of the motor vehicle 100: • An obstacle detection module consisting of a microcontroller 130, and ultrasonic sensors 131, 132, 133, 134, 135 and 136 connected to the microcontroller 130, • A 140 touch screen, • A 120 speaker.

[0036] At step S00 [Fig.5], the vehicle 100 is stopped in a parking lot.

[0037] In step S10 [Fig.5], the microprocessor 110 determines a service state of the obstacle detection module, the operating status comprising a first piece of information 14li and a second piece of information 142i.

[0038] Determining the service status may include, for example: • A receipt of a message from the detection module (, the service status being determined from the message, and / or • A reading in memory of a data item in memory of the microcontroller 130 or of the microprocessor 110, the service state being determined from the data item.

[0039] In step S20 [Fig.5], the microprocessor 110 controls the display, on the first touch screen 140, of an icon 141 comprising the display of the first information 141i, as shown [Fig.2].

[0040] In step S30 [Fig.5], the microprocessor 110 detects a press on the icon 141 for a duration of 200 milliseconds, for example by the finger of the driver of the vehicle 100, and determines that the duration is strictly less than 600 milliseconds.

[0041] In step S40 [Fig. 5], the microprocessor 110 consequently controls the display on the first touch screen 140 of the second information 142i, for example in a window 142 of the first touch screen 140, as shown [Fig. 3].

[0042] At step S50 [Fig.5], the microprocessor 110 controls the closing of the window 142 upon detection of a press on the window 142.

[0043] In step S60 [Fig.5], the microprocessor 110 detects a press on the icon 141 for a duration of 950 milliseconds, and determines that the duration is greater than 600 milliseconds.

[0044] In step S70 [Fig. 5], the microprocessor 110 consequently controls the display on the first touch screen 140 of a parameter setting menu 143 of a parameter of the obstacle detection module, as shown [Fig. 4].

[0045] In step S80 [Fig.5], the microprocessor 110 configures the obstacle detection module upon detection of an action (for example a press) in the configuration menu 143 displayed by the touch screen 140.

[0046] The configuration of the detection module may include: • Sending an instruction to the microcontroller 130, and / or • Writing data into the memory of the microprocessor 140.

[0047] In step S90 [Fig.5], the microprocessor 110 commands the closing of the configuration menu 143 upon detection of a press on the configuration menu 143.

[0048] In operation, the parking assistance module comprises, for example, the following steps: • Reception of a message of detection of an obstacle 200 located at a distance dl of 1 meter from the vehicle 100, by the microprocessor 110, from the microcontroller 130, following the detection of the obstacle 200 by the ultrasonic sensors 133 and 134, the message comprising the position of the obstacle 200. • Control, by the microprocessor 110, of a restitution inside the passenger compartment of the motor vehicle 110, of the position of the obstacle 200 for example by the touch screen 140 or by a loudspeaker 120.

[0049] For example, the first information 14li indicates whether the detection module is in a deactivated or activated service state, and the second information 142i indicates a due to the service status which may be, for example, voluntary or involuntary deactivation of the obstacle detection module.

[0050] According to another example, the first information 14li indicates an operating anomaly of the obstacle detection module. The first information 14li may, in this case, for example, be displayed, for 10 seconds, upon detection of the first motor vehicle 100 shifting into reverse gear.

[0051] In this case, the second information 142i indicates an action to be carried out to remedy the anomaly, for example cleaning an ultrasonic sensor 131, 132, 133, 134, 135 or 136.

[0052] For example, the parameter is one (at least) of: • An activation or deactivation state of the obstacle detection module, • A sensitivity of the obstacle detection module (for example, its range), • The amplitude of a sound, emitted by the speaker 120, restoring a location of the obstacles (for example, a pulse increasing in frequency when the obstacle is closer to the vehicle) detected by the obstacle detection module.
