Description of the examples of realization

A method and a device for unlocking a door of a vehicle will now be described in the following with reference to FIGS. 1 to 3. The same elements are identified with the same reference signs throughout the description. who will follow.

According to a particular and non-limiting embodiment of the present invention, a method for unlocking a door of a vehicle comprises the reception, by an on-board processor of the vehicle, of first information representative of an attempt to open the door. opening, that is to say an action of using the opening of the locked vehicle.

By opening within the meaning of the present, is meant here and throughout the following description any element of the vehicle that can be locked and giving access to a function or part of the vehicle. This is for example a door of the vehicle giving access to the passenger compartment, a trunk door of the vehicle giving access to the trunk, a charging hatch giving access to a battery of an electric vehicle, or even a bonnet of the vehicle. Depending on the design, the method according to the invention applies to the unlocking of a particular opening of the vehicle or of a plurality of openings, for example a general unlocking of the vehicle or even an unlocking of a specific opening, in particular of a loading hatch without unlocking the other openings of the vehicle.

The first set of sensors comprises for example a single sensor associated with the opening of the vehicle, and allowing for example its opening when the vehicle is unlocked. This is for example a touch sensor or a sensor associated with the opening mechanism of the sash. According to another design, the first set of sensors comprises a plurality of sensors making it possible, for example, to detect a potential user of the vehicle, the attempt to open the door then corresponding to an approach of the door by the potential user.

Depending on the first information, the processor displays graphic content outside the vehicle via display means, in particular display means integrated into the vehicle and allowing for example its communication or its lighting when driving the vehicle . This design thus allows the reuse of lighting means already present on the vehicle. The graphic content is advantageously representative of an unlocking interface, that is to say a visual element encouraging the user to a specific interaction for unlocking the vehicle, for example a keypad, a numeric code or even a light code.

The processor then receives second information representative of a command entered via the unlocking interface, that is to say of an action by the user vis-à-vis the unlocking interface. The second information is advantageously received from a second set of sensors integrated into the vehicle, for example sensors integrated into a surface on which the unlocking interface is projected and/or a camera whose field of vision includes the unlocking interface .

Depending on the second information, the processor then unlocks the opening, for example when the second information corresponds to a sequence recorded in a memory of the processor or any other data validating the authorization to unlock the opening.

The opening of the vehicle is thus unlocked in a secure manner without requiring the use or possession of a key, a smart phone or any other specific product or device, and thus simplifying access to the vehicle for authorized persons .

schematically illustrates a vehicle 1 comprising a plurality of openings 11, 12, 13, according to a particular and non-limiting embodiment of the present invention.

There illustrates a vehicle 1, for example a motor vehicle, which is locked and has at least one opening 11, 12, 13. According to other examples, the vehicle 1 corresponds to a car, a bus, a truck or even a utility vehicle , that is to say a vehicle of the motorized land type. As stated above, the at least one opening 11, 12, 13 corresponds to an element of the vehicle 1 which can be locked and gives access to a function or part of the vehicle. The at least one opening 11, 12, 13 belongs for example to a set of openings comprising a door 11 and/or a trunk 12 (or trunk door giving access to a trunk of the vehicle 1) and/or a charging 13 of an electric vehicle 1. According to other designs, the set of openings also comprises a bonnet and/or a fuel flap of the vehicle 1.

In a first operation, at least one processor of the vehicle 1, for example a central computer or a set of computers, receives first information representative of an attempt to open the opening 11, 12, 13 from a first set of vehicle-integrated sensors 1.

The at least one processor comprises for example an intelligent service box or BSI (in English “Built-In Systems Interface”) or even a VSM (from English “Vehicle Supervisor Module” or in French “Module de Supervision de Vehicule ”) capable of forming a communication network, for example a multiplexed communication network, in which data is transmitted via a wireless or wired link, for example data received from on-board sensors. The at least one processor or BSI (hereinafter referred to as "BSI") is thus connected to a plurality of peripheral computers, for example to the peripheral computers associated with the opening of the openings 11, 12, 13 and/or with other computers of on-board systems of the vehicle 1, for example driving assistance systems, called ADAS (from the English “Advanced Driver Assistance System” or in French “Advanced Driving Assistance System”). ADAS systems, for example, implement methods based on the detection of surrounding obstacles using peripheral sensors on board a vehicle such as cameras, radars, or even lidars (from the English "Light Detection And Ranging" , or “Detection and estimation of distance by light” in French).

The BSI thus receives the first information by communication in the multiplexed communication network, making it possible, for example, to identify and/or characterize the interactions with the openings 11, 12, 13 of the vehicle 1.

According to a variant, the first information is for example generated from data representative of the environment of the vehicle 1, for example data obtained by one or more sensors of object detection system(s) on board the vehicle 1, this or these systems being for example part of an ADAS system of the vehicle 1.

By way of example, the sensor(s) associated with these object detection systems correspond to one or more of the following sensors:

- one or more millimeter wave radars arranged on the vehicle 1, for example at the front, at the rear, on each front/rear corner of the vehicle 1; each radar being adapted to emit electromagnetic waves and to receive the echoes of these waves returned by one or more objects, with the aim of detecting obstacles and their distances vis-à-vis the vehicle 1; and or

- one or more LIDAR(s), a LIDAR sensor corresponding to an optoelectronic system composed of a laser transmitter device, a receiver device comprising a light collector (to collect the part of the light radiation emitted by the transmitter and reflected by any object located on the path of the light rays emitted by the transmitter) and a photodetector which transforms the collected light into an electrical signal; a LIDAR sensor thus makes it possible to detect the presence of objects located in the light beam emitted and to measure the distance between the sensor and each object detected; and or

- one or more cameras (associated or not with a depth sensor) for the acquisition of one or more images of the environment around the vehicle 1 located in the field of vision of the camera or cameras.

The data obtained from this or these sensors varies according to the type of sensor. When it is a radar or a LIDAR, the road environment data corresponds for example to distance data between points of the detected object and the sensor. Each detected object is thus represented by a cloud of points (each point corresponding to a point of the object receiving the radiation emitted by the sensor and reflecting at least part of this radiation), the cloud of points representing the envelope (or a part of the envelope) of the detected object as seen by the sensor and ultimately by the vehicle 1 carrying the sensor. In the case of a video camera, the road environment data corresponds to data associated with each pixel of the acquired image or images, for example values of gray levels coded on for example 8, 10, 12 or more bits for each color channel, for example RGB (from English “Red, Green, Blue” or in French “Rouge, vert, bleu”).

According to another variant, the first information is generated from sensors integrated into the openings 11, 12, 13 of the vehicle 1, for example sensors associated with the opening and/or locking mechanisms of the openings 11, 12, 13, and communicated to the BSI in the multiplexed communication network. The vehicle 1 for example incorporates a first set of sensors associated with the opening of the openings 11, 12, 13 when these are unlocked and with the method according to the invention when these are locked, the same action of attempting to opening allowing the opening of the openings 11, 12, 13 and the generation of the first information according to the state of the openings 11, 12, 13.

Of course, a variant is also designed in which the first set of sensors comprises ADAS system sensors of vehicle 1 in combination with sensors of openings 11, 12, 13 of vehicle 1.

In a second operation, display means 14, 15, 16 on board vehicle 1 display graphic content 17, 18 according to the first information. The BSI processes for example the first information and transmits a display command to the display means 14, 15, 16 for the display of the graphic content 17, 18.

Such graphic content 17, 18 is advantageously representative of an unlocking interface, that is to say of one or more interactive elements prompting the user, that is to say here the person responsible for the attempt opening of the opening 11, 12, 13, to act in a given way according to the graphic content 17, 18, preferably to interact directly with the graphic content 17, 18. Here a graphic content 17 is provided, 18 taking the form of a digicode, a keyboard or any set of elements allowing the composition of a code or an unlocking sequence. Of course, other embodiment variants are also designed in which the graphic content 17, 18 takes an alternative form appropriate to the desired unlocking action, for example prompting an action allowing biometric recognition of the user.

According to a variant, the display means 14, 15, 16 comprise at least one luminous indicator 14 integrated into the vehicle 1, for example a position light and/or a scrolling indicator. The light indicator 14 corresponds for example, among the set of light indicators of the vehicle 1, to that closest to the opening 11, 12, 13, for example a right (or left) rear light for opening of the charging hatch 13 and/or of the trunk 12. The graphic content 17, 18 displayed by the luminous indicator 14 corresponds for example to an ignition of the luminous indicator 14 according to a plurality of zones, each zone being representative of an individual element of the code or sequence to be composed by the user. The indicator light 14 can be activated partially so as to clearly separate several distinct zones, certain zones then being extinguished, or even activate different zones according to different colors, for example positioned randomly to limit the risks of disclosure of the sequence of unlocking.

According to yet another variant, the display means 14, 15, 16 comprise a ground projector 15 integrated in at least one rear-view mirror of the vehicle 1, that is to say in a lighting lamp under the rear-view mirror, for example such as described in document WO2010015118A1. Such a ground projector 15 thus makes it possible, in its conventional use, to illuminate the ground around the vehicle 1, in particular around the doors of the vehicle 1 to secure the entry and exit of the vehicle 1 by illuminating the direct environment of the vehicle 1 or even to facilitate the maneuvers of the vehicle 1. The BSI thus transmits a display command to the projector on the ground 15, which implements the graphic content 17, 18, in particular the graphic content on the ground 17 arranged in front of the door 11 of the vehicle 1.

Optionally, the display means further comprise a retractable mirror 16 associated with the ground projector 15. The BSI therefore transmits in the second operation a deployment command for the retractable mirror 16, the latter then positioning itself so as to intersect the beam light emitted by the projector on the ground 15 and redirect it, so as to form a reflected graphic content 18 on a portion that is easier to access, for example on a bodywork of the vehicle 1, in particular directly on the door 11 of the vehicle 1. A following the attempt to open the door 11, the combined action of the projector on the ground 15 and of the retractable mirror 16 thus allows the display of the reflected graphic content 18 as close as possible to the user to directly encourage his interaction with the unlock interface. According to an additional design, the retractable mirror 16 is also used to facilitate the opening of the door 11 in low light conditions, by at least partially redirecting the lighting of the ground projector 15 towards the door 11.

According to an additional variant, the vehicle comprises a plurality of display means 14, 15, 16, for example two light indicators 14 corresponding to the left and right rear lights and two ground projectors 15 respectively associated with a retractable mirror 16 and the rear view mirrors external left and right. The BSI then proceeds to a selection of a display means among the plurality of display means 14, 15, 16 according to the first information, the display command being transmitted to the selected display means. It is understood here that the display means selected corresponds to the display means closest to the opening attempt identified and therefore to the presumed presence of the user. One of the light indicators 14 is for example selected for unlocking a rear door 11 of the vehicle 1, a boot 12 and/or a charging hatch 13, the left or right light indicator 14 being selected according to the arrangement of the door 11 or of the recharging hatch 13 or even according to an angle of approach of the user resulting from the first information, while the projector on the ground 15 and optionally associated retractable mirror 16 is selected for the unlocking of a front door 11 of the vehicle 1 or, according to another design, a front bonnet of the vehicle 1.

In a third operation, the BSI receives second information representative of a command entered via the unlocking interface and, depending on this second information, unlocks the opening in a fourth operation. The BSI unlocks for example the opening 11, 12, 13 specifically concerned by the method according to the invention or even a set of openings of the vehicle 1, for example all of the doors of the vehicle 1. The second information is advantageously received a second set of sensors integrated into the vehicle and for example associated with the openings 11, 12, 13.

According to one design, the second set of sensors comprises at least one touch sensor and/or at least one brightness sensor making it possible to detect interactions with the unlocking interface, for example integrated into the light indicator 14 and/or the body portion of the vehicle 1 on which the reflected graphic content 18 is projected.

According to another design, the second set of sensors comprises at least one camera, for example as described above with regard to the first set of sensors, and whose field of vision comprises the graphic content 17, 18, for example the content graphic on the ground 17 or the graphic content reflected 18, so as to perceive the interactions with the graphic content 17, 18. The camera is for example also associated with the rearview mirror, like the projector on the ground 15 and the retractable mirror 16.

The second information thus comprises an interaction datum with the unlocking interface, which is compared by the BSI with a reference datum, for example a datum stored in the memory of the BSI, the correspondence of the interaction datum with the reference datum conditioning the unlocking of the opening 11, 12, 13. The interaction datum corresponds for example to a sequence of interactions with elements of the unlocking interface, the interaction sequence being compared to a sequence reference for unlocking the opening 11, 12, 13. For example, provision is made for the reference datum to be initialized by the manufacturer and optionally modifiable by interaction with the BSI via an on-board HMI (Human-Machine Interface) system or even an IVI (In-Vehicle Infotainment) system when the vehicle is unlocked, or via an application implemented p ar a connected device, for example a smart phone, allowing authorized users to control the unlocking methods of the vehicle 1. According to another design, such unlocking methods are individualized between the openings of the vehicle 11, 12, 13, allowing by example the recording of reference data specific to the opening of the charging hatch 13 or more generally to control the level of protection of the various openings 11, 12, 13 of the vehicle 1 according to the functions or parts of the vehicle 1 to which the openings 11, 12, 13 provide access.

Thus, the unlocking of the opening 11, 12, 13 of the vehicle 1 is carried out without requiring the carrying of a specific object, allowing for example the user to enter and exit the vehicle 1 without having keys or connected device, for example by leaving them inside the vehicle 1 for a reduced bulk, while remaining secure vis-à-vis potential intrusions by the implementation of a specific unlocking interface requiring only the use vehicle on-board systems 1.
