Description

Method for resuming actuation of a motor vehicle, associated device and motor vehicle

The invention relates to a method for controlling an actuation of a vehicle. There is a need to make these actuation controls safer, while remaining comfortable and simple to use.

• Réception d’une instruction d’un actionnement (autrement dit de manière générale : d’un mouvement) du véhicule,
• Vérification répétée, par triangulation radio à partir (d’information reçues, ou autrement dit : du délai de réponse de l’objet connecté à un message reçu de la part des récepteurs radio) des au moins trois récepteurs radio, si un objet connecté est dans une zone prédéterminée,
• Commande d’actionnement du véhicule, la vérification ayant déterminée qu’aucun objet connecté est dans la zone prédéterminée, puis
• Inhibition de l’actionnement du véhicule, la vérification ayant déterminée qu’un objet connecté est dans la zone prédéterminée (alors que le déplacement a débuté), puis
• Commande automatique de reprise de l’actionnement du véhicule, la vérification ayant déterminé que plus aucun objet connecté n’est dans la zone prédéterminée.

For this purpose, the invention relates to a method of controlling a motor vehicle, the vehicle comprising at least three radio receivers (in other words: three transmitters/receivers or radio devices), the control method comprising the following steps:

• Receipt of an instruction for an actuation (in other words generally: a movement) of the vehicle,
• Repeated verification, by radio triangulation from (information received, or in other words: the response time of the connected object to a message received from the radio receivers) of at least three radio receivers, if a connected object is in a predetermined area,
• Vehicle actuation command, verification having determined that no connected object is in the predetermined zone, then
• Inhibition of vehicle operation, verification having determined that a connected object is in the predetermined zone (while movement has started), then
• Automatic control for resuming vehicle operation, verification having determined that no connected object is in the predetermined zone.

Automatic resumption of actuation thus allows smooth, secure operation for the user.

The actuation resumption command is automatic in the sense that it is initiated independently of interactions between a human and a human machine interface (such as a touch keyboard or a button) to control the resumption.

The inhibition of the actuation may include a step of controlling the inhibition of the actuation of the vehicle. On receipt of the inhibition command, actuation stops or does not take place. Alternatively, no command is issued, which has the effect of inhibiting actuation.

Inhibiting the actuation can be an interruption of the actuation (i.e.: the movement is stopped) or an implementation of the actuation at reduced speed.

On receipt of the actuation command, the vehicle is actuated (and the actuation step may be part of the method according to the invention).

The actuation may be a movement of the vehicle or the actuation of a moving part of the vehicle. The actuation can be the opening or closing of an opening of the vehicle.

If the actuation is a movement, the actuation command controls the implementation of a propulsion motor of the vehicle to move (in other words: move) the vehicle on a roadway. Alternatively, in this case, the actuation control releases (in other words: deactivates) a parking brake of the vehicle (which causes the vehicle to move, for example if the roadway is on a slope or if the vehicle is pushed).

If the actuation is the opening or closing of an opening of the vehicle, the actuation controls a motor and/or a cylinder (in other words, more generally: an automation) to open or close the opening.

For example, the actuation instruction is received from a remote control, from a human machine interface of the vehicle (button, touch screen for example) or from another trigger.

The connected object can be paired with the electronic device implementing the method according to the invention, prior to the verification step.

Radio triangulation is, for example, implemented in three dimensions. That is to say that the object is positioned in a three-dimensional frame.

Checking whether a connected object is in the predetermined zone can be implemented based on an estimation of the position of the object. The position of the object can be estimated from the time to receive (for the at least three radio receivers) a response from the connected object to a message sent by the at least three radio receivers.

The verification can be carried out upon receipt of the actuation command. The verification is then carried out during the course of the process repeatedly (for example, 10 times per second). The actuation check can be repeated until the actuation is complete.

For example, the at least three radio receivers are ultra wide band receivers known as "ultra wide band" (registered trademark) or receivers known as "Bluetooth" (registered trademark). The at least three radio receivers can include both “ultra wide band” receivers and “Bluetooth” receivers, for example to improve the reliability and performance of the verification. The at least three radio receivers may include four or more radio receivers, for better spatial coverage of the volumes surrounding the vehicle. For example, the at least three receivers include three receivers for inside coverage and four additional receivers for outside coverage (e.g., one at each corner of the bumpers).

• Emission d’un message d’avertissement, si l’étape de vérification détermine qu’un objet connecté est dans la zone prédéterminée.

According to one embodiment, the control method further comprises the following step:

• Emission of a warning message if the verification step determines that a connected object is in the predetermined zone.

For example, the vehicle has a passenger compartment and the warning message is issued inside the passenger compartment.

According to one embodiment, the warning message is issued by a screen, inside the passenger compartment.

The warning message can also be audible.

Alternatively, the warning message can be emitted by the vehicle outside the vehicle or be emitted by the connected object or a remote control for opening and closing the motor vehicle.

The predetermined area is outside (the body) of the vehicle. It is preferably contiguous to the vehicle.

• L’actionnement est l’actionnement d’une pièce mobile du véhicule,
• La zone prédéterminée comprend des trajectoires d’actionnement de la pièce mobile.

According to one embodiment:

• Actuation is the actuation of a moving part of the vehicle,
• The predetermined zone includes actuation trajectories of the moving part.

The moving part may be an opening. An opening can be, for example, a door, an engine hood, a movable roof (opening, convertible) or a luggage compartment hatch. Alternatively, the moving part may be a rearview mirror. The moving part can be inside or outside the bodywork (this is the case, for example, of a rear-view mirror), or be part of the bodywork (this is the case, for example, of the openings).

The actuation of the opening can be a closing of the opening, and then the trajectory can be a closing trajectory of the opening.

Alternatively, the actuation of the opening may be an opening of the opening, and then the trajectory may be an opening trajectory of the opening.

Actuation is, for example, the movement of a vehicle.

• le véhicule comprend un soubassement et un toit, et
• la zone prédéterminé comprend un premier volume, au-dessous du véhicule, s’étendant entre le soubassement et une chaussée sur laquelle se trouve le véhicule (et/) ou un deuxième volume s’étendant au-dessus du véhicule (autrement dit : s’étendant au-dessus du toit).

For example :

• the vehicle includes a base and a roof, and
• the predetermined zone comprises a first volume, below the vehicle, extending between the base and a roadway on which the vehicle is located (and/) or a second volume extending above the vehicle (in other words: s 'extending above the roof).

Thus, the first volume extends below the vehicle and the second volume extends above the vehicle, when the vehicle is moving (in normal operation) on the roadway.

The second volume extends for example between the roof and a height h1 (for example, greater than 2.5 meters) predetermined relative to (in other words: above or on) the roadway (greater than the height of the roof relative to the roadway).

According to one embodiment, the actuation is a movement of the vehicle in one direction and one direction and the predetermined zone is in front of the vehicle (that is to say that the vehicle will pass over the predetermined zone, when moving in the direction and direction) when the vehicle is moving in the direction and direction.

The invention also relates to a computer program comprising instructions, executable by a microprocessor or a microcontroller, for implementing the method according to the invention, when the computer program is executed by the microprocessor or a microcontroller.

The method is for example implemented by an electronic device. The electronic device has, for example, the architecture of a computer, a microcontroller or a microprocessor. This is for example a server.

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 according to the invention.

The characteristics and advantages of the electronic device, the motor vehicle, and the computer program are identical to those of the process, which is why they are not repeated here.

It is understood that an element such as the electronic device or another element is “configured to” carry out or implement a step or an operation, by the fact that the element comprises means for (in other words “is configured for” or “is suitable for”) carrying out the step or operation. These are preferably electronic means, for example a computer program, data in memory and/or specialized electronic circuits.

When a step or an operation is carried out (in other words: implemented) by such an element, this generally implies that the element includes means for (in other words "is designed for" or "is adapted for" or "is configured to) perform the step or operation. It also concerns, for example, electronic means, for example a computer program, data in memory and/or specialized electronic circuits.

Detailed description of an example of embodiment of the invention

With reference to Figures 1, 2, 3, and 4 in step S10, the electronic device 110 of a vehicle 100 receives, from a remote control 200, an instruction for actuation of the vehicle 100.

The electronic device 110 has for example the architecture of a microprocessor (or several microprocessors) and can be connected to the radio receivers 130, 140, 150 and 160, and to the screen 120, of the vehicle by a wired or wireless connection. thread.

, the radio receivers 130, 140, 150 and 160, and the screen 120 are not shown, to simplify the drawing. Likewise, and 2, the base 170 is not shown.

In step S20, the device 110, using the radio receivers 130, 140, 150 and 160, determines the position of the connected object 500 by radio triangulation. The time to receive a response from the object 500 to a message sent by at least three of the radio receivers 130, 140, 150 and 160 is measured to deduce the three-dimensional position of the connected object 500, and thus check whether the connected object 500 is in a predetermined zone.

For example, radio receivers 130, 140, 150, 160 are ultra-wideband receivers or known as "Bluetooth" (registered trademark).

The connected object 500 can be paired with the electronic device 110, prior to sending the message.

The connected object 500 is for example a mobile phone of a regular passenger of the vehicle (a teenager for example).

The verification can be carried out upon receipt of the movement command and then repeated throughout the following steps of the process (as shown by the fact that step S20 extends between step S10 and step S50).

In step S30, the actuation of the vehicle 100 is inhibited due to the presence of the connected object 500 in the predetermined zone, detected by the verification in step S20.

Inhibiting the actuation may include a step of controlling the inhibition of the actuation of the vehicle 100. On receipt of the inhibition command, the actuation ceases or does not take place. Alternatively, no command is issued.

Inhibiting the actuation can be an interruption of the actuation (i.e.: the movement is stopped) or an implementation of the actuation at reduced speed.

During a step S15, implemented between step S10 and step S30 (that is to say, after step S10 and before step S30), the device 110 may have controlled the actuation of the vehicle 100 due to the absence of connected objects in the predetermined area during step S15 (detected during verification step S20).

On receipt of the actuation command, the vehicle 100 is actuated. The actuation can be a movement of the vehicle 100 or the opening or closing of an opening of the vehicle 100.

If the actuation is a movement, the actuation command controls the implementation of a propulsion motor of the vehicle 100 to move (in other words: move) the vehicle 100 on the roadway 400.

If the actuation is the opening or closing of an opening of the vehicle 100, the actuation controls a motor and/or a cylinder (in other words: automatic) to open or close the opening.

In step S40, the electronic device 110 controls the display by the screen 120 (inside the passenger compartment of the vehicle 100) of a message warning that the object 500 is present in the predetermined zone.

In step S50, the electronic device 110 determines, using the radio receivers 130, 140, 150 and 160, that the connected object 500 has left the predetermined zone and that no other connected object is in the predetermined area. The electronic device 110 then consequently controls the resumption of actuation of the vehicle 100.

The actuation resumption control is automatic in the sense that it is implemented without interaction between a human and a human machine interface (such as a touch keyboard or a button) to control the resumption.
