Description

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

[0001] The invention relates to the guidance of motor vehicles.

[0002] There is a need to improve safety during the use of motor vehicles.

[0003] For this purpose, the invention relates to a method for guiding a motor vehicle comprising a human-machine interface (located for example in a passenger compartment of the motor vehicle), the method comprising the following steps: - Receipt of a current identifier from a current driver of the motor vehicle, - Receiving a current geographic location of the motor vehicle, - (Following the identifier reception step and the location reception step,) If the current identifier is a first identifier, implementation of the following exclusion steps: - Obtaining a geographic exclusion zone from the current identifier, then - Determination of information from the current geographic location and the geographic exclusion zone, then - (Sending, to the human-machine interface, of a) Command for the restitution of information by the human-machine interface (for example in the passenger compartment of the motor vehicle),

[0004] The invention thus makes it possible to inform the current driver of a geographical exclusion zone associated with him, and thus to improve safety during use of the motor vehicle by the current driver.

[0005] The steps of receiving an identifier and receiving a location can be implemented in any (temporal) order relative to each other.

[0006] The geographic location can be received for example from a satellite geographic location module or an inertial module.

[0007] The method may comprise a step of comparing the current identifier with the first identifier (which may be stored in the memory of the electronic device introduced later) to determine whether the identifier is the first identifier. Alternatively, it is searched directly (for example in a table) whether a geographical exclusion zone is associated with the current identifier (if this is the case then the current identifier is the first identifier).

[0008] The geographic exclusion zone can be read from the vehicle's memory or received (e.g. via a mobile telecommunications network) from a remote server.

[0009] The rendering may be performed, for example, by a vehicle screen or a vehicle speaker. Conventionally, rendering a route may consist of displaying the entire route or parts of the route to guide a driver of the vehicle along the route (while the vehicle is traveling the route).

[0010] The geographic area may be in the shape of a rectangle, a square, a disc, a polygon, or a free form.

[0011] The geographical area can be entered via the human-machine interface, for example via the screen if it is touch-sensitive, following receipt of a third identifier (from a driver authorized to make the entry).

[0012] According to one embodiment, the method according to the invention further comprises the following step: - If the current identifier is a second identifier, different from the first identifier, inhibition of the exclusion steps.

[0013] By inhibition of the exclusion steps, it is meant that none of the exclusion steps are carried out.

[0014] According to one embodiment, the steps of determining the information and controlling the restitution are implemented on condition that the current geographical location is in the geographical exclusion zone (or at a distance from the exclusion zone less than a predetermined threshold), the information being a warning message (that the current geographical location is in the geographical exclusion zone or at a distance from the exclusion zone less than a predetermined threshold).

[0015] Thus informed, the current driver can drive (or drives) the vehicle to exit or move away from the exclusion zone (and the method according to the invention can include this step).

[0016] According to one embodiment, the method further comprises a step of receiving, from the human-machine interface (for example, by voice recognition or manual entry) a request for route guidance from the motor vehicle, between the current geographical location and the geographical destination, the information comprising a first route between the current geographical location and the geographical destination avoiding (or bypassing) the geographical exclusion zone.

[0017] Thus informed, the current driver can drive (or drives) the vehicle to complete the first route (and the method may include this step) which bypasses the geographic exclusion zone.

[0018] Alternatively, the information is the geographical exclusion zone and the control of the restitution of the information takes place when the propulsion engine of the vehicle is started.

[0025] automobile. For example, the inhibition step includes the following steps: - Determination of a second route between the current geographical location and the geographical destination crossing the geographical exclusion zone, then - (Sending, to the human-machine interface, of a) Command for a restitution of the second route by the human-machine interface. Thus informed, the current driver can drive (or drives) the vehicle to complete the second route (and the method may include this step) and cross the exclusion zone. According to one embodiment, the exclusion steps comprise the following steps: - (Sending, to the human-machine interface, of a) Command to return, by the human-machine interface, an invitation to select a third route between the current geographical location and the geographical destination crossing the geographical exclusion zone then - Received notification of selection of the third route, then - Determination of the third route, then - (Sending, to the human-machine interface, of a) Command for a restitution of the third route by the human-machine interface. The first route, the second route and / or the third route is for example determined from a road map, for example in the memory of the vehicle or the electronic device. According to one embodiment, the current driver identifier is received from one of: - A mobile phone (e.g. via radio frequency or wired communication), or - A camera (located for example in a passenger compartment of the motor vehicle), the identifier being for example one or more images of the current driver's face received from the camera, or - An electronic ignition key for the motor vehicle, or - A smart card or remote control for the motor vehicle. The current driver ID is for example received by: - Via radio frequency communication (for example, near field, or via a mobile telecommunications network), or - Wired communication. For example, the guidance process includes the following step: - Upon receipt of the current identifier, authentication of the identifier, for example from cryptographic data (for example, a cryptographic certificate) which may be contained in the identifier or received with the identifier.

[0026] According to one embodiment, the motor vehicle comprises openings and a propulsion engine.

[0027] According to one embodiment, the method according to the invention further comprises the following step (implemented after the identifier authentication step): - If the identifier is authenticated, (sending to the openings of a) command to unlock the openings or (sending of a) command or authorization to start the propulsion engine.

[0028] The invention also relates to a computer program comprising instructions, executable by a microprocessor or a microcontroller or a computer, for implementing the steps of the method according to the invention, when it is 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.

[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, automated 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.

[0032] For example, the electronic device comprises a microprocessor or a microcontroller.

[0033] 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 comprising the electronic device according to an embodiment of the invention, - [Fig.2] is a geographical representation of a vehicle location of [Fig.l], of a geographical exclusion zone and determined routes during steps of the process of [Fig.6], - [Fig.3], [Fig.4] and [Fig.5] represent the display of a screen of the vehicle of the [Fig.l] at various stages of the process of [Fig.6]. - [Fig.6] represents an implementation of the method according to the invention, according to a example of embodiment, by the electronic device and the motor vehicle of [Fig.l].

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

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

[0036] [Fig.l] represents a motor vehicle 100 comprising, connected to an electronic device 110 which may be a microprocessor, the following components: - A satellite geographic location module 120, - A touch screen 150 (inside the passenger compartment of the motor vehicle 100), - A propulsion motor 170, - Openings 130, 140 and 160.

[0037] The remainder of the description of the exemplary embodiment generally refers to Figures 1 to 6.

[0038] In step S00, the owner of the motor vehicle 100 identifies himself to the electronic device 110 using the smart card 200. For this, the electronic device 110 receives, from the smart card 200, an identifier, which is compared by the electronic device 110 with a second identifier in memory 112. The identifier may also include a cryptographic signature which allows the electronic device 110 to carry out an authentication of the identifier. If the result of the comparison and the authentication is positive (which is assumed to be the case here), the electronic device 110 unlocks the openings 130, 140 and 160 of the vehicle and authorizes a start of the propulsion engine 170.

[0039] In step S00, the motor vehicle is located at the geographical location 510. The geographical location 510 can be received by the electronic device 110, for example from the satellite geographical location module 120.

[0040] In step S10, the electronic device 110 detects a press on a button of the motor vehicle 100 and commands a start of the propulsion engine 170 accordingly.

[0041] In step S20, a geographic exclusion zone 530 is entered by the owner of the vehicle 100 via the touch screen 150 and is stored in memory 112. This geographic exclusion zone 530 is associated with a first identifier of the son of the owner of the vehicle in memory 112. The owner of the vehicle 100 wishes to limit the risk of his son driving in dangerous zones such as the geographic exclusion zone 530.

[0042] In step S30, the electronic device 110 receives a route guidance request. of the motor vehicle 100, between the geographical location 510 and a geographical destination 520, from the screen 150, following manual entry by the owner on the screen 150. The owner of the motor vehicle 100 wishes to collect a package from the geographical destination 520.

[0043] In step S40, the electronic device 110 determines the route it2 between the geographical location 510 and the geographical destination 520 in a manner known to those skilled in the art (for example, by searching for a shortest path, between the geographical location 510 and the geographical destination 520) from the road map 111 stored by the electronic device 110.

[0044] In step S50, the electronic device 110 controls the display of the route it2 on the screen 150. As shown [Fig.5], it2 is represented on the screen 150 by the line tr_it2 in the representation map2 of a part of the road map 111.

[0045] The owner could have decided to drive (or drives) the vehicle to complete route it2. However, the travel time indicated for route it2 is not compatible with his schedule. He then leaves the vehicle, orders the locking of the openings 130, 140 and 160 of the vehicle 100 using the smart card 200, then asks his son to go and collect the package at destination 520.

[0046] In step S60, the son identifies himself to the electronic device 110 using the smart card 300. For this, the electronic device 110 receives an identifier, from the smart card 300, which is compared by the electronic device 110 with a first identifier in memory 112. The identifier may also include a cryptographic signature which allows the electronic device 110 to authenticate the identifier. If the result of the comparison and authentication is positive (which is assumed to be the case here), the electronic device 110 unlocks the openings 130, 140 and 160 of the vehicle and authorizes starting of the propulsion engine 170. At this step, the motor vehicle is still located at the geographical location 510.

[0047] In step S70, the electronic device 110 detects a press on a button of the motor vehicle and commands a start of the propulsion engine 170 accordingly.

[0048] In step S80, the electronic device receives a request for route guidance of the motor vehicle, between the geographical location 510 and the geographical destination 520, from the screen 150, following manual entry by the owner's son on the screen 150.

[0049] In step S90, the electronic device 110 finds, in the memory 112, the geographic exclusion zone 530 associated with the first identifier.

[0050] In step S100, the electronic device 110 determines a route itl between the geographical location 510 and the geographical destination 520 avoiding the geographical exclusion zone 530. The determination of the route itl is carried out in a manner known to those skilled in the art (for example, by searching for a shortest route avoiding the geographic exclusion zone 530, between the geographic location 510 and the geographic destination 520) from the road map 111 stored by the electronic device 110.

[0051] In step S1 10, the electronic device 110 controls the display of the route itl on the screen. As shown [Fig.4], itl is represented on the screen 150 by the line tr_it 1 in the representation mapl of a part of the road map 111.

[0052] The owner's son could have decided to drive (or drives) the vehicle to complete the itl route. However, the travel time indicated for the itl route is very long due to roadworks. As shown [Fig.4], the screen 150 also displays at this stage an invitation invl to select a route between the geographical location 510 and the geographical destination 520 crossing the geographical exclusion zone 530.

[0053] In step S120, the electronic device 110 receives a notification of a press on INV1 on the screen 150 from the owner's son.

[0054] In step S130, the electronic device calculates the route it2 and displays it, as shown [Fig.5], in the same manner as in steps S40 and S50.

[0055] The owner son then drives the vehicle 100 to complete the route it2.

[0056] In step S140, the electronic device 110 detects that the motor vehicle 100 is in the exclusion zone 530 (the location of the vehicle is received from the satellite geographic location module 120).

[0057] In step S150, the electronic device 110 searches in memory 111 for a warned warning message and controls the display of the warned warning message by the screen 150, as shown [Fig.3].

[0058] It may be noted that if the owner had driven the vehicle 100 to complete the route it2, after or at step S50, no warning message would then have been issued (in other words: the issuing of the warning message would have been inhibited), the exclusion zone 530 not being associated with the second identifier.
