Description

Method and device for controlling the field of vision of at least one camera of a digital rearview system of a parked vehicle

The present invention relates to methods and devices for controlling a digital rearview system of a vehicle. The present invention also relates to a method and a device for controlling the field of vision of one or more cameras of a digital rearview system of a vehicle.

Technology background

Digital rearview solutions are appearing on the vehicle market. A digital rearview system proposes replacing the exterior mirrors and/or the interior rearview mirror commonly used with solutions comprising, for example, external cameras communicating with internal screens and displaying on the internal screens the images acquired by the external cameras.

One of the benefits of digital rearview solutions is that they allow an increase in the width of the view. In a classic mirror solution, the viewing angles are limited by the size of the mirrors and the geometry of the vehicle, whereas in a digital solution it is enough to adapt the camera lens according to the desired view.

When the vehicle is parked, with the engine off, such digital rearview systems are no longer operational. In particular, the processors associated with controlling the rearview system are likely to be inactive for the sake of energy saving, and the exterior elements of the vehicle, in particular the external cameras, are likely to be folded down for their protection and/or or compliance with local regulations regarding protruding parts of vehicles.

Description of the implementation examples

A method and a device for controlling a digital vehicle rearview system will now be described in what follows with reference jointly to Figures 1 to 3. The same elements are identified with the same reference signs throughout the description which follows.

According to a particular and non-limiting example of an embodiment of the present invention, a digital rearview system comprises at least one on-board camera configured to acquire at least one image in a determined field of vision. The at least one camera is for example associated with one or more display screens arranged in the passenger compartment of the vehicle, in particular arranged at the level of the dashboard or the doors of the vehicle. The control of such a digital rearview system comprises the detection of a command to change the orientation of the at least one camera, for example of a folding of the at least one camera or of a support associated with this when the camera is no longer necessary for driving. The orientation of the at least one camera is then controlled so as to allow its passage through a first field of vision comprising at least one rear part of an external environment of the vehicle, corresponding for example to a field of vision allowing ensure its rearview function, to a second field of vision comprising at least one lateral part of an external environment of the vehicle, for example oriented along a transverse axis of the vehicle so as to ensure a surveillance function of a perimeter around the vehicle.

Controlling the orientation of the at least one camera thus makes it possible to use it outside of driving situations to monitor a perimeter around the vehicle while folding it down to avoid damage, particularly when the vehicle is parked.

This design thus makes it possible to reuse digital rearview cameras while improving vehicle safety.

schematically illustrates a vehicle 10 carrying a digital rearview system, according to a particular and non-limiting embodiment of the present invention.

The vehicle 10 corresponds for example to a vehicle with a thermal engine, with an electric motor(s) or even a hybrid vehicle with a thermal engine and one or more electric motors. The vehicle 10 thus corresponds for example to a land vehicle, for example an automobile, a truck, a coach.

The vehicle 10 advantageously carries a digital rearview system controlled by one or more computers of the on-board system of the vehicle 10. An example of such a computer is described below with regard to the .

A digital rearview system corresponds to a system according to which one or more conventional mirror-type rearview mirrors, for example the exterior mirrors (left and/or right) and/or the central interior rearview mirror, are each replaced by an associated display screen to an exterior camera (or to an interior camera arranged behind a glass wall to be able to acquire images of the exterior environment of the vehicle) of the vehicle which acquires images of the exterior environment of the vehicle 10 to be displayed on the associated display screen.

Thus, the digital rearview system of the vehicle 10 comprises one or more exterior cameras 11, 12, each being associated with a display screen placed in the passenger compartment 13 of the vehicle 10.

A process for controlling the digital rearview system of the vehicle 10 is for example implemented by an on-board device in the vehicle 10, for example one or more processors of one or more computers of the on-board system of the vehicle 10.

For example, the process is implemented by a single computer in charge of the entire digital rearview system, such a computer controlling all of the cameras 11, 12 and all of the display screens associated with these cameras. 11, 12.

According to another example, each camera 11, 12 (and the associated display screen) is controlled by a particular computer. Thus, when the digital rearview system comprises two cameras 11, 12, the rearview system is controlled by two computers, these computers being for example controlled by a central computer of the on-board system of the vehicle 10.

According to yet another example, the cameras 11, 12 are controlled by one or more digital rearview computers when the vehicle 10 is in operation, for example computers directly associated with the display screens of the vehicle 10. When the vehicle 10 is not no longer in operation, for example when it is parked and/or when its engine is turned off, the digital rearview computers are no longer in operation and the process is implemented by a central computer of the vehicle 10. Obviously, we also designs an alternative embodiment in which the digital rearview computers remain in operation when the vehicle 10 is parked.

The central computer of the vehicle corresponds for example to an intelligent service box or BSI (in English “Built-In Systems Interface”) or even VSM (from the English “Vehicle Supervisor Module” or in French “Module de Supervision de Véhicule” ) capable of forming a communication network, for example a multiplexed communication network, in which data is transmitted via a wireless or wired connection, for example data received from on-board sensors, in particular cameras 11, 12. The central computer or BSI (hereinafter referred to as “BSI”) is thus connected to a plurality of peripheral computers, for example to the rearview computers of the vehicle 10 and/or to other on-board system computers of the vehicle 10.

In a first operation of this process, the BSI detects a command to change the orientation of the at least one camera 11, 12. The cameras 11, 12 are for example installed on folding supports in place of the mirrored rear-view mirrors and the orientation change control corresponds for example to a folding control of the cameras 11, 12.

According to a variant, the command corresponds to an engine stop and/or a locking of the vehicle 10. The BSI receives for example information representative of the engine stopping and/or the locking of the vehicle, or even of a cessation of operation rearview computers, reception of the information initiating the change of orientation of the cameras 11, 12.

According to another variant, the control corresponds to manual actuation of the cameras 11, 12, that is to say to a manual folding of the at least one camera, which is for example supported at least partially by a motor electric controlled by the BSI. Manual actuation of the cameras 11, 12, via direct action by a user on the cameras 11, 12 or even the use of an associated interface element, for example a button in the passenger compartment 13 of the vehicle 10 allowing the folding of the cameras 11, 12, then triggers their control according to the process.

In a second operation, the BSI controls the orientation of the cameras 11, 12 for the transition from a first field of vision 111, 121 to a second field of vision 112, 122.

According to the example of the , the vehicle 10, seen from below, comprises a left camera 11 and a right camera 12. The first left field of vision 111 associated with the left camera 11 and the first right field of vision 121 associated with the right camera 12 are each illustrated by a dotted triangle. The first field of vision 111, 121 comprises at least a rear part of an external environment of the vehicle 10 and corresponds for example to the field of vision of the cameras 11, 12 when the vehicle 10 is traveling, so as to allow the driver of the vehicle 10 to visualize the exterior rear environment of the vehicle 10 like a conventional rearview mirror.

In this same example, the second left field of vision 112 associated with the left camera 11 and the second right field of vision 122 associated with the right camera 12 are each illustrated by a grayed triangle in solid lines. The second field of vision 112, 122 comprises at least one lateral part of the exterior environment of the vehicle 10, that is to say that the cameras 11, 12 are oriented towards the exterior of the vehicle 10, along a transverse axis to the vehicle. The second field of vision 112, 122 is for example oriented on either side of the side parts of the vehicle so as to observe a perimeter outside the vehicle.

Thus, generally speaking, the field of vision of the images acquired by the cameras 11, 12 corresponds to the first field of vision 111, 121 when the vehicle is in operation and/or when the cameras 11, 12 are deployed and to the second field of view. vision 112, 122 when the vehicle is stationary and/or when the cameras 11, 12 are folded down.

The field of vision of an image corresponds for example to the field of vision of the cameras 11, 12 having acquired this image. The field of view of a camera is also called visual field or angle of view. Such a field of vision is for example defined by the proportion between the focal length of the lens of the camera 11, 12 and the size of the image sensor of the camera 11, 12.

According to the design, controlling the orientation of the cameras 11, 12 (passage from the first field of vision 111, 121 to the second field of vision 112, 122) corresponds to controlling their folding from a deployed position associated with the first field of vision 111, 121 to a folded position associated with the second field of vision 112, 122, or to an adjustment of the angle of view of the cameras 11, 12 as a function of the angle of inclination of their support.

It can be noted that in this folding position when locking the vehicle, the camera supports pivot forward, instead of pivoting rearward as conventionally in the state of the art. With this new position, the cameras are oriented towards the outside of the vehicle, which is well suited to monitoring an intrusion in a perimeter outside the vehicle and allowing, for example, biometric identification of a user who approaches the vehicle.

According to another design, for example in which the cameras 11, 12 and/or their supports are fixed, the adjustment of the field of vision of the cameras 11, 12 is obtained by performing digital processing on the image(s) received from the cameras 11 , 12. Such processing corresponds for example to a selection of a portion of the images received to reduce the field of vision of the original images received from the cameras 11, 12, thus making it possible to move from the first field of vision (corresponding for example to a field of vision in operation of the vehicle, that is to say the field of vision necessary to fill the driver's blind spots) to the second field of vision, which is oriented towards a lateral part of an environment outside the vehicle. Such processing is also called cropping of the image.

When the cameras 11, 12 are oriented towards the second field of vision 112, 122, they thus transmit the images they acquire to the BSI, for example via one or more computer buses, for example a communication bus of the CAN data bus type (from the English “Controller Area Network” or in French “Réseau de controllers”), CAN FD (from the English “Controller Area Network Flexible Data-Rate” or in French “ Network of controllers with flexible data rate"), FlexRay (according to the ISO 17458 standard) or Ethernet (according to the ISO/IEC 802-3 standard) connecting the different devices (computers, cameras).

Obviously, we understand that when the cameras 11, 12 are oriented towards the first field of vision 111, 121, they transmit the images that they acquire to the display screens of the vehicle 10, for example by intermediate rearview computers.

According to a variant embodiment, the images received according to the second field of vision are recorded in a memory, for example a memory associated with a BSI processor or even a memory of a device on board the vehicle 10. This design thus makes it possible to make a video surveillance type recording that can be used later by accessing the memory.

According to another variant, the BSI transmits at least one image according to the second field of vision to a remote device 110, for example a server of a surveillance database or a connected device of a driver of the vehicle 10 , for example a computer or a smartphone. This operation makes it possible to relocate the storage of images and allow remote consultation without the need to access the vehicle 10.

According to an exemplary embodiment, the vehicle 10 advantageously communicates with the remote server 110 using a V2X communication system, for example based on the 3GPP LTE-V standards (from the English “Long-Term Evolution” or in French “Evolution long term") or IEEE 802.11p of ITS G5. In such a V2X communication system, each vehicle has a node to enable V2V vehicle-to-vehicle (vehicle-to-vehicle) and vehicle-to-vehicle-to-infrastructure (V2I) communication. -infrastructure") and/or vehicle-to-pedestrian V2P, pedestrians being equipped with mobile devices (for example a smartphone) configured to communicate with vehicles.

The network infrastructure comprises for example a communication device 101, corresponding for example to an antenna of a cellular network of the LTE 4G or 5G type or to a UBR (“Roadside Unit”), each corresponding to a node of the network, in addition to the nodes equipping vehicles or pedestrians.

According to a particular example of embodiment, all of the nodes (that is to say the communications devices associated with the vehicle 10 and the antenna or UBR 101) of the network form for example an ad hoc wireless network (also called WANET (from English "Wireless Ad Hoc Network") or MANET (from English "Mobile Ad Hoc Network"), corresponding to a decentralized wireless network. The ad hoc wireless network advantageously corresponds to an ad hoc vehicular network (or VANET, from the English “Vehicular Ad hoc NETwork”) or to an intelligent ad hoc vehicular network (or InVANET, from the English “Intelligent Vehicular Ad hoc NETwork”), also called a “GeoNetworking” network. network, 2 or more vehicles each carrying a node can communicate with each other as part of vehicle-to-vehicle V2V communication; each vehicle can communicate with the infrastructure set up as part of vehicle-to-infrastructure V2I communication; each vehicle can communicate with one or more pedestrians equipped with mobile devices (for example a smartphone) as part of vehicle-to-pedestrian V2P communication. ").

The node corresponding to the antenna (or UBR) 101 is advantageously connected to the remote server 110 or to the “cloud” 100 via a wired and/or wireless connection. The antenna or UBR 101 can thus act as a relay between the remote server 110 and/or the “cloud” 100 and the vehicle 10.

According to another example of embodiment, the vehicle 10 carries an autonomous telematics box, called BTA, in communication with the BSI inside the multiplexed network and making it possible to communicate with the remote server 110 outside the V2X communication network, for example a 3G, 4G or 5G BTA allowing wireless communication within a 4G LTE type cellular network. The vehicle 10 communicates for example with the remote server 110 and/or the cloud 100 via the antenna or UBR 101, via another antenna of the LTE 4G type cellular network in communication with the remote server 110, or even directly with the server remote 110.

According to another variant, the BSI processes the images received according to the second field of vision 112, 122 so as to detect an intrusion in a perimeter around the vehicle 10, for example any movement inside the perimeter around the vehicle 10 during the execution of the process, this being triggered for example when the vehicle 10 is locked and the second field of vision 112, 122 being focused on the interior of the perimeter around the vehicle, any movement on a key element of the second field of vision 112, 122,.

Depending on a detection result, the BSI implements the rendering of an alert, for example the emission of a siren-type audio signal in the vehicle 10. According to a variant, the BSI transmits representative information of the intrusion to a remote device 110, for example the same remote device 110 as described above or even a monitoring center. The representative information corresponds for example to the images which enabled the detection of the intrusion, transmitted via the BTA to the remote device 110.

Controlling the orientation of the cameras 11, 12 thus makes it possible to benefit from their use when the vehicle 10 is stationary, in particular so as to monitor a perimeter around the vehicle 10.

In a first embodiment, the images captured by the cameras are used to identify a potential intrusion or another event likely to compromise the safety of the vehicle 10.

In a second embodiment, the images captured by the cameras are used to perform biometric identification of a user. In this case, biometric identification can work as follows:

• Searching the camera image for an area with a face; this zone is only selected if its size is greater than a predefined value, which corresponds to a distance sufficiently close to the vehicle (for example less than 2 m)
• Verification of vehicle access authorization by comparison of the face acquired by the camera with the base of faces configured for the vehicle
• if the authentication is valid, then two operating modes are possible:
  • immediate unlocking of the vehicle (either only of the front door on the side of the camera which carried out the detection, or of all the openings), or
  • unlocking the vehicle (either only from the front door on the side of the camera which carried out the detection, or from all the openings), after detection of a hand on the door opening handle.
