Description

Title of the invention: Method and device for a malicious act detection alert for vehicles technical field

[0001] The present invention relates to methods and devices for alerting and detecting a malicious act, such as an attempted intrusion or damage, to a first vehicle, for example, but not exclusively, a motor vehicle. The present invention also relates to a method and device for wireless data communication between the first vehicle and one or more second vehicles. Technological background

[0002] Vehicles, and in particular motor vehicles, are subject to malicious acts such as attempted thefts or material damage caused by malicious individuals. For example, some thefts of items left inside the vehicle are perpetrated by breaking a window or forcing a door lock to gain access to the passenger compartment. Among the attempted thefts, one technique used by thieves involves lifting the vehicle while it is parked, for example, to load it onto a truck or van and transport it to a location where the thieves will attempt to unlock the vehicle. Another technique involves lifting part of the vehicle, for example, one of the wheels, using a jack to steal that wheel.

[0003] To protect vehicles and their components from theft attempts, some vehicles are equipped with alarms that are triggered when an intrusion, lifting, or movement of the vehicle is detected. Such an alarm corresponds, for example, to one of the following three types: perimeter alarms, volumetric alarms, and tilt-detection alarms.

[0004] Some of these alarms are configured to communicate wirelessly with a mobile communication device such as a smartphone belonging to the vehicle owner, in order to alert the owner in the event of an attempted break-in or theft of the vehicle. Communication takes place via a terrestrial wireless cellular network based on a wireless communication technology such as 4G or 5G.

[0005] A problem arises when the vehicle targeted by the attempted theft, intrusion, or any malicious act is located in a so-called "white zone," that is, in an area not covered by the wireless network enabling the transmission of the alert. In In such a situation, the vehicle owner cannot receive the alert and cannot take the necessary steps to prevent the malicious act. Summary of the present invention

[0006] One object of the present invention is to solve at least one of the problems of the technological background described above.

[0007] Another object of the present invention is to improve the communication of an alert for the detection of a malicious act on a vehicle.

[0008] According to a first aspect, the present invention relates to a method for alerting the detection of malicious acts on a first vehicle, the first vehicle comprising a receiver of a satellite geolocation system, the method being implemented by at least one processor and comprising the following steps: - receipt of initial data representative of the detection of the malicious act from at least one sensor on board the first vehicle; - generation of second data representing the alert based on the first data, the second data including a first information representative of a current position of the first vehicle obtained from the receiver; - transmission of the second data to a set of second vehicles including at least one second vehicle using a vehicle-to-everything wireless communication mode, known as V2X.

[0009] Wireless communication of an alert associated with the detection of a malicious act by one or more sensors onboard the first vehicle, via a V2X wireless communication method, to one or more second vehicles allows the driver or owner of these second vehicles to be alerted. This wireless communication method relies on a communication infrastructure different from that of a conventional terrestrial cellular network and also allows direct vehicle-to-vehicle communication, thus resolving the problem of coverage gaps. Transmitting the alert to one or more second vehicles, along with the geographical location of the first vehicle, allows the driver or owner of these second vehicles to take the necessary steps, for example, contacting the authorities, to stop the malicious act and / or to avoid leaving their vehicle in the area detected as being at risk.

[0010] According to one variant, the transmission includes a transmission of the second data to at least a first part of the set of second vehicles in a direct wireless vehicle-to-vehicle communication mode, known as V2V, and / or a transmission of the second data to at least a second part of the set of second vehicles via a wireless network infrastructure in a wireless vehicle-to-infrastructure communication mode, known as V2I.

[0011] According to another variant, the second data further include a second piece of information representative of a type of malicious act committed on the first vehicle, the second piece of information being determined based on the first data.

[0012] According to yet another variant, at least one sensor belongs to a set of sensors comprising: - a camera: - a presence detector; - a door opening detector; - a glass break detector; - an anti-uplift detector; and - a battery disconnection sensor.

[0013] According to a further variant, the process further comprises the following steps: - reception of the second data by at least one second vehicle from the set of second vehicles according to the V2X wireless communication mode; - transmission of the second data to a mobile communication device via a wireless connection.

[0014] According to yet another variant, the wireless connection corresponds to a connection via a terrestrial cellular wireless network or to a vehicle-to-pedestrian type connection, known as V2P.

[0015] According to an additional variant, the transmission of the second data to a mobile communication device is implemented only for the second vehicle or vehicles located at a distance from the first vehicle less than a determined threshold distance.

[0016] According to a second aspect, the present invention relates to a device for alerting an attempt to damage a first vehicle, the device comprising a memory associated with a processor configured for the implementation of the steps of the process according to the first aspect of the present invention.

[0017] According to a third aspect, the present invention relates to a vehicle, for example of the automobile type, comprising a device as described above according to the second aspect of the present invention.

[0018] According to a fourth aspect, the present invention relates to a system comprising a first vehicle as described above according to the second aspect of the present invention and a set of second vehicles comprising at least one second vehicle connected in wireless communication to the first vehicle according to a V2X wireless communication mode, the system being configured for the implementation of the steps of the process according to the first aspect of the present invention.

[0019] According to a fifth aspect, the present invention relates to a computer program which includes instructions adapted for carrying out the steps of the process according to the first aspect of the present invention, in particular when the computer program is executed by at least one processor.

[0020] Such a computer program may use any programming language, and be in the form of source code, object code, or an intermediate code between source code and object code, such as in a partially compiled form, or in any other desirable form.

[0021] According to a sixth aspect, the present invention relates to a computer-readable recording medium on which is recorded a computer program comprising instructions for carrying out the steps of the process according to the first aspect of the present invention.

[0022] On the one hand, the recording medium can be any entity or device capable of storing the program. For example, the medium can include a storage means, such as a ROM, a CD-ROM or a microelectronic circuit-type ROM, or a magnetic recording means or a hard disk drive.

[0023] On the other hand, this recording medium can also be a transmissible medium such as an electrical or optical signal, such a signal being able to be transmitted via an electrical or optical cable, by conventional or radio frequency, by self-directing laser beam, or by other means. The computer program according to the present invention can, in particular, be downloaded from an Internet-type network.

[0024] Alternatively, the recording medium may be an integrated circuit in which the computer program is incorporated, the integrated circuit being adapted to execute or to be used in the execution of the process in question. Brief description of the figures

[0025] Other features and advantages of the present invention will become apparent from the description of the particular and non-limiting embodiments of the present invention below, with reference to the attached Figures 1 to 3, in which:

[0026] [Fig.1] schematically illustrates a data communication environment for a first vehicle and a set of second vehicles, according to a particular embodiment of the present invention;

[0027] [Fig.2] illustrates a device configured for the alert of malicious act detection on the first vehicle of the [Fig.1], according to a particular and non-limiting embodiment of the present invention.

[0028] [Fig. 3] illustrates a flowchart of the different stages of a malicious act detection alert process on the first vehicle of [Fig. 1], according to a particular and non-limiting embodiment of the present invention. Description of embodiment examples

[0029] A method and a device for detecting malicious acts on a first vehicle will now be described in what follows with joint reference to Figures 1 to 3. The same elements are identified with the same reference signs throughout the description that follows.

[0030] The terms "first," "second" (or "firsts," "seconds"), etc., are used in this document by arbitrary convention to allow for the identification and distinction of different elements (such as operations, means, etc.) implemented in the embodiments described below. Such elements may be distinct or correspond to a single element, depending on the embodiment.

[0031] According to a particular and non-limiting embodiment of the present invention, the alert of a detected malicious act perpetrated on a first vehicle is implemented by one or more processors of one or more computers in the first vehicle, the first vehicle being equipped with a receiver for a satellite geolocation system. To this end, initial data representing the detection of the malicious act are received by the computer from at least one sensor onboard the first vehicle, for example, a camera or an intrusion detector. The computer generates second data representing the alert from the first data. This second data includes initial information representing the current position of the first vehicle obtained from the onboard receiver.This second data is then transmitted to one or more second vehicles using a vehicle-to-everything wireless communication method, known as V2X.

[0032] Such a V2X (Vehicle-to-Everything) wireless communication mode corresponds to a broadcast mode configured to broadcast the alert to all other vehicles. This type of communication encompasses various communication modes such as vehicle-to-vehicle (V2V) communication or vehicle-to-infrastructure (V2I) communication.

[0033] Fig. 1 schematically illustrates a wireless data communication environment between a first vehicle 11 and a set of second vehicles 12 to 14, according to a particular and non-limiting embodiment of the present invention.

[0034] The first vehicle 11 and each second vehicle 12, 13, 14 each correspond, for example, to a vehicle with an internal combustion engine, with electric motor(s) or even a hybrid vehicle with a combustion engine and one or more electric motors. The first vehicle 11 and the second vehicle(s) 12, 13, 14 thus each correspond, for example, to a land vehicle, for example a car, a truck, a bus.

[0035] According to the particular example of [Fig. 1], the set of second vehicles comprises 3 second vehicles 12, 13, 14. Of course, the invention is not limited to this example and extends to any set of second vehicles comprising one or more second vehicles, regardless of the number of second vehicles.

[0036] The first vehicle 11 and the second vehicles 12, 13, 14 correspond to so-called connected vehicles, that is to say, vehicles configured to communicate data via a wireless communication method, for example through a wireless network infrastructure or via a direct communication method. The communication method is advantageously of the broadcast type and more particularly of the V2X type, for example V2V and / or V2I.

[0037] To this end, the first vehicle 11 and each second vehicle 12, 13, 14 each comprise a communication system or interface including, for example, one or more communication antennas connected to a telematic control unit, known as a TCU (Telematic Control Unit), which is itself connected to one or more computers of the vehicle's on-board system. The antenna(s), the TCU, and the computer(s) form, for example, a multiplexed architecture for providing various services useful for the proper functioning of the vehicle and for assisting the driver and / or passengers in controlling the vehicle.The computer(s) and the TCU communicate and exchange data with each other via one or more computer buses, for example a CAN (Controller Area Network), CAN FD (Controller Area Network Flexible Data-Rate), FlexRay (according to ISO 17458) or Ethernet (according to ISO / IEC 802-3) type communication bus.

[0038] A V2X communication system is for example based on the 3GPP LTE-V or IEEE 802.1 lp standards of ITS G5. In such a V2X communication system, each vehicle carries a node (or wireless communication system / interface) to enable vehicle-to-vehicle (V2V), vehicle-to-infrastructure (V2I) and / or vehicle-to-pedestrian (V2P) communication, with pedestrians being equipped with mobile devices (for example, a smartphone) configured to communicate with the vehicles.

[0039] The network infrastructure includes, for example, communication devices 101, 102, each device 101, 102 corresponding, for example, to a UBR (“Roadside Unit”), each corresponding to a node of the network, in addition to the nodes equipping the vehicles.

[0040] According to a particular embodiment, the set of nodes (i.e., the wireless communication systems or interfaces associated with the vehicles 11, 12, 13, 14 and the UBRs 101, 102) of the network forms, for example, a wireless ad hoc network (also called a WANET (from the English "Wireless Ad Hoc Network") or a MANET (from the English "Mobile Ad Hoc Network")), corresponding to a decentralized wireless network. The wireless ad hoc network advantageously corresponds to a vehicular ad hoc network (or VANET, from the English "Vehicular Ad hoc NETwork") or to an intelligent vehicular ad hoc network (or InVANET, from the English "Intelligent Vehicular Ad hoc NETwork"), also called a "GeoNetworking" network.In such a network, two or more vehicles, each carrying a node, can communicate with each other in vehicle-to-vehicle (V2V) communication; each vehicle can communicate with the infrastructure in place in vehicle-to-infrastructure (V2I) communication; each vehicle can communicate with one or more pedestrians equipped with mobile devices (for example, a smartphone) in vehicle-to-pedestrian (V2P) communication.

[0041] The nodes corresponding to UBR 101 and 102 are advantageously connected to one or more remote servers 110 or to the "cloud" 100 (or in French "nuage") via a wired and / or wireless connection. UBR 101 and 102 can thus act as a relay between the "cloud" 100 and its servers 110 on the one hand, and the first and second vehicles 11, 12, 13, 14 on the other (i.e., each connected vehicle configured to travel in a platoon).

[0042] According to a particular embodiment, the first vehicle 11 and at least a first part of the set of second vehicles communicate with each other using a direct communication mode, which is, for example, compliant with: - ITS G5 in Europe or DSRC (Dedicated Short Range Communications) in the United States of America, both of which are based on the IEEE 802.1 lp standard; or - LTE-V Mode 4 (Long-Term Evolution - Vehicle Mode 4), which allows V2V communications, also called "sidelink" communications, based on a direct LTE communication interface called PC5; such a technology is described, for example, in the article entitled "Analytical Models of the Performance of C-V2X Mode 4 Vehicular Communications”, written by Manuel Gonzalez-Martin, Miguel Sépulcre, Rafael Molina-Masegosa and Javier Gozalvez, and published in 2018.

[0043] According to another particular embodiment, the first vehicle 11 and at least a second part of the set of second vehicles communicate via the wireless network infrastructure, indirectly, in particular via one or more UBRs 101, 102.

[0044] According to the particular example of [Fig. 1], the first part of the set of second vehicles comprises only one second vehicle 12 and the second part of the set of second vehicles comprises 2 second vehicles 13, 14. Of course, the first part may comprise several second vehicles or no second vehicle when no second vehicle of the set of second vehicles is within range of the communication unit of the first vehicle 11. In the same way, the second part may comprise any number of second vehicles, or even no second vehicle.

[0045] The first vehicle 11 advantageously comprises or carries a geolocation system receiver enabling the first vehicle 11 to obtain data or information representative of its geographic position at any time, for example in the form of coordinates (latitude and longitude), via a satellite link with a set of satellites (not shown in [Fig. 1]). The geolocation system corresponds, for example, to a GPS (Global Positioning System), Galileo, or GLONASS type system. The geographic position obtained for the first vehicle 11 from a geolocation system is said to be absolute in that the coordinates are expressed in the same frame of reference for all vehicles equipped with such a receiver, namely the world frame of reference.

[0046] The first vehicle 11 also carries one or more sensors configured for the acquisition of data relating to a malicious act, for example an attempted intrusion, an attempted theft of the first vehicle 11, an attempted theft of one or more parts of the first vehicle 11 (for example one or more wheels, the battery, etc.) or damage or harm caused to the first vehicle 11 (broken window, scratch on the bodywork, etc.).

[0047] This or these sensors belong to a set of sensors comprising: - one or more cameras, for example a camera arranged in the passenger compartment and / or one or more external cameras arranged on the bodywork or external components (for example the exterior mirrors) of the first vehicle 11: - a presence detector, for example an infrared camera, a capacitive proximity sensor or an inductive proximity sensor; - a door opening detector; - a glass break detector, for example a sensor that acquires frequencies emitted by sound vibrations caused by glass breakage; - an anti-uplift detector; and - a battery disconnection sensor.

[0048] The above list is provided as a purely illustrative example and is not exhaustive.

[0049] A malicious act detection alert process on the first vehicle 11 is advantageously implemented by a device or system embedded in the first vehicle 11 such as a computer, i.e. by one or more processors of this device.

[0050] In a first operation of the process, first representative data for the detection of the malicious act are received from one or more sensors on board the first vehicle 11 and adapted for the detection of a malicious act such as a broken window, a lifting of the first vehicle 11, an unauthorized opening of a door or the trunk, a disconnection of the battery to stop the electrical supply of the first vehicle 11, material damage caused to an element of the first vehicle 11, etc.

[0051] This initial data is, for example, received by the computer from this or these sensors or from one or more computers controlling this or these sensors via a data bus each time a malicious act is detected.

[0052] In a second operation of the process, a processing of the first data is implemented to generate second data representative of a malicious act detection alert.

[0053] In this second operation, a first information representative of the current position of the first vehicle 11 at the time of the detection of the malicious act or at the time of the generation of the second data is obtained from the receiver of the geolocation system or from a memory storing the current position obtained from the receiver.

[0054] This first piece of information is obtained, for example, by reading from memory or by transmitting a request to the receiver to obtain the first piece of information.

[0055] The first piece of information is added to the second data generated from the first data.

[0056] According to one embodiment, a second piece of information representative of the type of malicious act committed on the first vehicle 11 is also added to the second data.

[0057] The second piece of information is obtained from the first data, for example as a result of processing applied to the first data for this purpose.

[0058] The type of malicious act is adapted to identify the nature of the malicious act, for example from the following types: intrusion into the passenger compartment, theft of the vehicle, theft of a part of the vehicle, breaking glass, opening a door, lifting the vehicle, impact on the vehicle, etc.

[0059] In a third operation of the process, the second data is transmitted to the set of second vehicles 12 to 14 according to a vehicle-to-everything wireless communication mode, known as V2X.

[0060] The set of second vehicles includes, for example, any second vehicle 12 within range of the first vehicle according to the direct vehicle-to-vehicle communication mode, known as V2V.

[0061] According to another example, the set of second vehicles further includes any second vehicle connected to the infrastructure. According to this other example, the second data is transmitted to the infrastructure according to the V2I communication mode, which infrastructure relays the second data to the set of second vehicles 13, 14 that are connected to it (according to an I2V (Infrastructure-to-Vehicle) communication mode).

[0062] The first vehicle 11 transmits the second vehicle alert to any vehicle in broadcast mode without identifying a specific recipient. This allows the alert to be disseminated as widely as possible to any second vehicle connected directly and / or indirectly to the first vehicle 11.

[0063] Direct V2V communication transmission has the advantage of not being dependent on infrastructure, as this communication mode is always available when the on-board communication system of the first vehicle 11 is operational. According to a particular embodiment, the wireless communication system of the first vehicle 11 includes a dedicated battery-type power supply to enable it to transmit the alert even when the main power supply to the first vehicle 11 has been cut off or disconnected.

[0064] In a fourth operation of the process, the alert is given in the second vehicle or vehicles that received the second data transmitted by the first vehicle 11.

[0065] The alert rendering includes, for example, the display of graphic content on a screen installed in each second vehicle that has received the alert, the graphic content including, for example, text and / or a pictogram indicating the alert. Advantageously, the graphic content includes the first piece of information to indicate the location of the first vehicle 11. According to one variant, the graphic content also includes the second piece of information.

[0066] According to a particular embodiment, the second vehicle(s) receiving the second data and located at a distance greater than a predetermined threshold distance from the first vehicle 11 ignore the second data received and do not issue an alert. The distance separating a second vehicle from the first vehicle 11 is determined by the second vehicle based on the first piece of information contained in the second data and information representative of a position of the second vehicle (for example, obtained from a receiver of a geolocation system of the second vehicle). The determined threshold distance is, for example, equal to 1 km. According to other examples, this threshold distance is equal to 2, 5, or 10 km.According to this particular embodiment, second vehicles located too far from the first vehicle 11 do not take the alert into account, which reduces the load on the computer responsible for rendering the alert and processing the second data and reduces the volume of information rendered to the driver of the second vehicle.

[0067] According to another particular embodiment, the second data further includes a third piece of information representing an identifier of the first vehicle 11 added to the second data during the generation of the second data. The identifier corresponds, for example, to the registration number of the first vehicle 11. According to this particular embodiment, the graphic content includes this third piece of information.

[0068] According to one embodiment, the rendering of the alert further includes the generation of a sound or the rendering of the content of the alert by speech synthesis via one or more loudspeakers of each second vehicle which received the second data.

[0069] According to yet another particular embodiment, the process further includes the transmission of the second data by each second vehicle having received it to a mobile communication device connected in mobile communication to this or these second vehicles.

[0070] For example, according to the example in [Fig. 1], the second data is transmitted by the second vehicle 12 to a mobile communication device 121, for example a smartphone, via a wireless connection linking this second vehicle 12 to the mobile communication device 121. In the same way, the second data is transmitted by the second vehicle 13 to a mobile communication device 131, for example a smartphone, via a wireless connection linking this second vehicle 13 to the mobile communication device 131.

[0071] The wireless connection linking a second vehicle 13, 14 to a mobile communication device 121, 131 corresponds, for example, to: - a wireless connection using a direct communication method, for example based on Wifi ® or Bluetooth®; - a wireless connection using a direct communication method, for example based on a vehicle-to-pedestrian (V2P) communication method; or - a wireless connection based on a terrestrial wireless cellular network infrastructure, for example based on LTE 4G or 5G.

[0072] The communication of the second data by a second vehicle 12, 13 to a mobile communication device 121, 131 is implemented by the wireless communication system or interface (for example the TCU) of the second vehicle 12, 13 considered.
