technical field

The embodiments of the present application relate to the field of terminal technologies, and in particular, to a V2X communication method and apparatus.

Background technique

The vehicle to everything (V2X) system is a new generation of information and communication technology that connects vehicles with everything. As shown in Figure 1, communication in the form of V2X can include, for example, vehicle to vehicle (V2V) communication, vehicle to pedestrian (V2P) communication, and vehicle to infrastructure (V2I) communication Wait. Among them, the vehicle relies on the in-vehicle communication terminal (telematics Box, T-Box) that supports V2X technology as the V2X information transceiver device, and can rely on the mature communication network architecture to form a V2X system with other things to realize V2X communication.

However, at present, the on-board T-Box in many vehicles (such as the stock vehicles that have been produced) does not support V2X technology, and these vehicles cannot obtain the ability to support V2X technology through software upgrade, resulting in these vehicles unable to support V2X communication. In the process of vehicle driving, since these vehicles cannot interact with other vehicles well and provide users with effective traffic information, driving safety and efficiency are reduced.

SUMMARY OF THE INVENTION

The V2X communication method and device provided by the embodiments of the present application can utilize the communication capability of the terminal device, so that vehicles that do not support V2X can implement V2X communication.

In order to achieve the above purpose, the embodiment of the present application adopts the following technical solutions:

In the first aspect, an embodiment of the present application provides a V2X communication method, which is applied to a first device. The method may include: determining that a target connection has been established with the vehicle, then starting the V2X mode of any vehicle connected to the vehicle; the communication address corresponding to the target connection is the target address. Receive vehicle status information sent by the in-vehicle communication terminal T-Box. According to the vehicle state information, the first V2X information is generated. Send the first V2X information to the second device, and receive the second V2X information sent by the second device.

In some embodiments, the in-vehicle T-Box is located in the controller area network in the vehicle, and uses the CAN bus to obtain vehicle status information detected by various modules in the vehicle. The vehicle state information includes, for example, vehicle four-axis acceleration, braking system state, lamp state, control, temperature, rotational speed, and other information. For example, the second device includes devices corresponding to traffic participants, such as road infrastructure devices, vehicles, terminal devices carried by pedestrians, and the like. For example, the V2X information includes basic safety messages and other event-type messages, such as vehicle speed, steering, braking, double flash, location and other information.

In this way, after determining to establish a communication connection with the vehicle, the first device can be used as an external V2X module of the vehicle to receive vehicle status information and generate V2X information. After that, the generated V2X information can be sent to the second device, so that vehicles that do not support the V2X function can also implement V2X communication.

In a possible implementation manner, the method further includes: determining alarm information according to the second V2X information. Send alarm information to the vehicle T-Box.

Among them, the warning information is used to indicate the information that the vehicle needs to give an early warning during the driving process, such as the information that other vehicles merge into the current driving road, the information of continuous curves, and the high-speed approach of other vehicles.

In some embodiments, the first device receives the second V2X information sent by the second device, determines that an abnormal situation occurs, and can generate alarm information and send it to the vehicle to prompt the vehicle to avoid danger and improve driving safety. In some embodiments, after determining the alarm information, the first device sends the alarm information to the in-vehicle T-Box, thereby realizing effective V2X information interaction with the vehicle during the driving process of the vehicle.

In a possible implementation manner, the target address includes a target service set identifier SSID or a target Internet Protocol IP address, the target SSID is the SSID in the wireless fidelity Wi-Fi network SSID provided by the vehicle, and the target IP address is the IP address corresponding to the vehicle address.

In some embodiments, an Ethernet communication connection is established between the first device and the vehicle to implement IP data packet (which can also be simply described as IP packet) communication. Wherein, the first device and the vehicle may establish a link carrying the IP packet through a wireless connection or a wired connection, so as to realize the transmission of the IP packet. For example, the first device accesses the vehicle Wi-Fi, establishes a Wi-Fi communication connection with the vehicle, and transmits IP packets. For another example, a communication connection is established between the first device and the vehicle through a USB interface, and an IP packet is transmitted.

In a possible implementation manner, determining that the target connection has been established with the vehicle includes: determining that the SSID of the Wi-Fi network accessed is the target SSID, and then determining the established target connection with the vehicle. Or, it is determined that the accessed IP address is the target IP address, and the established target connection with the vehicle is determined. Or, when the first operation is detected, it is determined that the target connection has been established with the vehicle; the first operation is used to instruct to start the V2X mode.

In some embodiments, the first device, for example, determines whether the current communication address is the target address, and then determines whether IP packet communication with the vehicle is currently possible, so as to determine whether to establish a communication connection with the vehicle. After it is determined that the IP packet communication with the vehicle is possible, the driving mode is activated (ie, the V2X mode is activated). For example, an IP packet communication connection can be established between the first device and the vehicle through a Wi-Fi network or USB, and after determining that the communication address accessed is the target address, it can be determined that the target connection has been established with the vehicle. Alternatively, the first device may also determine whether to activate the V2X mode by detecting the user's instruction. If the confirmation interface is displayed, the V2X mode is activated after detecting that the user clicks the confirmation control.

In this way, the first device can start the V2X mode after determining that the target connection is established with the target vehicle, as an external V2X module of the target vehicle, to avoid abnormal activation of the V2X module and invalid V2X information transmission.

Exemplarily, after switching the P2X mode to the V2X mode, the first device no longer judges the surrounding environment based on the information detected by its own sensors, cameras and other modules, but uses the vehicle status information sent by the received vehicle-mounted T-Box as the environment judgment. benchmark.

In this way, the first device acts as an external V2X module of the vehicle to transmit V2X information, so as to avoid information detected by its own sensors and other modules from interfering with the generation of V2X information corresponding to the vehicle.

In a possible implementation manner, the method further includes: receiving vehicle shutdown information sent by the vehicle-mounted T-Box. Turn off V2X mode.

The vehicle shutdown information includes, for example, vehicle shutdown information.

In some embodiments, after receiving the vehicle shutdown information, the first device determines that the vehicle has been turned off, and then disables the driving mode and stops sending and receiving V2X information. After turning off the driving mode, the first device converts its own V2X mode to a P2X mode. That is, it is no longer used as an external V2X module of the vehicle to transmit V2X information, but forms a P2X system with other devices, and uses its own sensors and other modules to detect the environmental information of the user.

In a possible implementation manner, before determining that the target connection with the vehicle has been established, the method further includes: receiving vehicle startup information sent by the vehicle-mounted T-Box.

The vehicle startup information includes, for example, vehicle ignition information.

In some embodiments, after the vehicle ignition is started, the vehicle-mounted T-Box obtains the vehicle ignition information, determines that the vehicle has been started, and sends the vehicle start information to the first device. Correspondingly, after receiving the vehicle start information, the first device determines that the vehicle has started.

In this way, the first device can automatically act as an external V2X module of the vehicle to perform V2X communication after the vehicle is started.

In a possible implementation manner, the method further includes: determining alarm information according to the second V2X information. Sending alarm information to the vehicle, where the alarm information is used to instruct the vehicle to voice broadcast and/or display the alarm.

In a possible implementation manner, the method further includes: determining alarm information according to the second V2X information. Sending warning information to the automatic driving control module, where the warning information is used to instruct the automatic driving control module to adjust the driving strategy according to the warning information.

In some embodiments, after monitoring the abnormal situation, the first device can directly send the abnormal situation (that is, the alarm information) to the automatic driving control module of the vehicle, that is, it does not need to be forwarded by the on-board T-Box, so that the automatic driving vehicle does not need to be forwarded. Adjust the efficiency of your driving strategy.

First, for ease of understanding, related terms and concepts that may be involved in the embodiments of the present application are first introduced below.

(1) Vehicle to everything (V2X)

V2X is used to realize the information exchange between vehicles and all entities that may affect the vehicle, so as to reduce the occurrence of accidents, slow down traffic congestion, reduce environmental pollution and provide other information services. At present, V2X technology can be a dedicated short range communication (DSRC) related to automobiles as defined in the Institute of Electrical and Electronics Engineers (IEEE) 802.11p, or a third-generation partner The cellular vehicle networking (cellular V2X, C-V2X) technology based on cellular mobile communication technology defined by the 3rd generation partnership project (3GPP). It should be clear that the application scenarios of the solutions provided in the embodiments of this application are not limited to the above-mentioned two mainstream implementations (DSRC and C-V2X) in the current V2X technology. The application scenario coverage of the embodiments of the present application is not exceeded.

Specifically, DSRC is also called direct V2X, and the vehicle can directly form a communication channel with a roadside unit (RSU) to realize V2X communication. In the early stage, V2X communication technology was mainly based on DSRC, and later, with the development of cellular mobile communication technology, C-V2X technology based on cellular communication technology appeared. C-V2X currently includes V2X systems based on LTE and future 5G, which is a powerful supplement to DSRC technology. It can realize V2X information interaction with the help of 3GPP ecosystem and continuous and perfect cellular network coverage, so that vehicles have the ability to communicate with road infrastructure, pedestrians and other The ability of traffic participants to communicate with each other in real time. Based on V2X technology, vehicles share information through channels to expand the perception range, so as to detect hidden threats and ensure that important warning information is timely and correctly pushed at critical moments. V2X technology can not only help improve vehicle safety performance and improve road traffic efficiency, but also promote the development of autonomous driving technology.

However, the on-board T-Box in a large number of existing vehicles does not support V2X technology, resulting in vehicles not supporting the establishment of V2X systems and information sharing.

(2) In-vehicle communication terminal (telematics Box, T-Box)

The in-vehicle T-Box is a communication device (or described as a component) configured in the vehicle. The in-vehicle T-Box is mainly used to communicate with other devices and/or other electronic devices in the vehicle, so as to display vehicle information and control the vehicle using electronic devices.

FIG. 2 is a schematic diagram of a communication system to which a V2X communication method according to an embodiment of the present application is applied. As shown in FIG. 2 , in some embodiments of the present application, the communication system includes a first device 100 and a vehicle 200 , wherein the first device 100 and the vehicle 200 may be connected through a wired network or a wireless network. This embodiment of the present application does not specifically limit the connection manner between devices.

Wherein, the first device 100 in this application can be, for example, a mobile phone, a tablet computer, a personal computer (PC), a personal digital assistant (PDA), a netbook, a wearable electronic device, an augmented reality technology (augmented reality technology) reality, AR) devices, virtual reality (virtual reality, VR) devices, smart speakers, robots, artificial intelligence (artificial intelligence (AI) devices and other devices, the present application does not make special restrictions on the specific form of the first device 100 .

Exemplarily, the in-vehicle T-Box 201 configured in the vehicle 200 may establish a wired connection with the first device 100 through a wired communication technology. For example, the in-vehicle T-Box 201 establishes a connection with the first device 100 through a serial bus (universal serial bus, USB) interface.

In another example, the in-vehicle T-Box 201 configured in the vehicle 200 may establish a wireless connection with the first device 100 through a wireless communication technology. The wireless communication technology may include wireless local area network (WLAN) (such as wireless fidelity (Wi-Fi) network), Bluetooth (bluetooth, BT) (such as traditional Bluetooth or low-power BLE Bluetooth) ), Zigbee, frequency modulation (FM), near field communication technology (NFC), infrared technology (infrared, IR), or general 2.4G/5G frequency band wireless communication technology communication technology.

For example, the wireless communication technology is Wi-Fi as an example for description. After the in-vehicle T-Box 201 and the first device 100 establish a Wi-Fi connection, the in-vehicle T-Box 201 can send vehicle information to the first device 100 through the Wi-Fi connection, and can receive the information sent by the first device 100. For example, the vehicle information sent by the vehicle-mounted T-Box 201 to the first device 100 includes, for example: image information inside or outside the vehicle collected by the vehicle through the camera device; data detected by sensors, etc. (such as position information, travel direction information, speed information, braking information, etc.), etc.; user voice detected by the built-in sound pickup device and other sounds in the surrounding environment, etc. For another example, the information sent by the first device 100 received by the vehicle-mounted T-Box 201 includes, for example, V2X information and the like. In this way, the vehicle 200 utilizes the communication between the vehicle-mounted T-Box 201 and the first device 100 to implement the V2X communication shown in FIG. 1 . It can be understood that, the vehicle 200 may also use other electronic control units (electronic control units, ECUs) in the vehicle 200 to establish a communication connection with the first device 100 to implement V2X communication.

In some embodiments, the in-vehicle T-Box 201 can provide a Wi-Fi network for the first device 100 to access. For example, after the first device 100 enters the vehicle-mounted T-Box 201 to provide Wi-Fi network coverage (as shown by the dotted box 21 in FIG. 2 ), the first device 100 will send the Wi-Fi network access to the vehicle-mounted T-Box 201 Request, in response to a user operation, the first device 100 establishes a Wi-Fi connection with the in-vehicle T-Box 201. Subsequently, after the first device 100 enters the coverage of the Wi-Fi network again, it can automatically establish a Wi-Fi connection with the in-vehicle T-Box 201 .

In some embodiments, as shown in FIG. 2 , the first device 100 can establish a wireless connection with the second device 300 to form a pedestrian to everything (P2X) system. The P2X system includes, for example, a direct-connected wireless communication system established between electronic devices carried by pedestrians, vehicles, and roadside infrastructure. Optionally, the second device 300 includes, for example, but not limited to, various mobile phones, tablet computers, PCs, PDAs, netbooks, wearable devices, AR devices, VR devices, smart speakers, robots, AI devices, vehicle device, computing device, or other processing device connected to a wireless modem; may also include subscriber units, cellular phones, smart phones, wireless data cards, personal digital assistants, PDA) computer, tablet computer, handheld device (handheld), laptop computer (laptop computer), machine type communication (machine type communication, MTC) terminal (terminal), user equipment (user equipment, UE), mobile terminal, etc. . For another example, the second device 300 may be a component in any of the foregoing devices (for example, a terminal device may refer to a chip system in any of the foregoing devices). The second device 300 involved in the embodiments of the present application may also be an on-board module, on-board module, on-board component, on-board chip or on-board unit built into the vehicle as one or more components or units. The on-board module, on-board module, on-board component, on-board chip or on-board unit can implement the method of the present application. Optionally, the second device 300 involved in this embodiment of the present application may also be a network device. The network equipment includes, for example, a roadside unit (RSU), an evolved Node B (eNB), a radio network controller (RNC), a Node B (Node B, NB), a base station control controller (base station controller, BSC), base transceiver station (base transceiver station, BTS), home base station (for example, home evolved NodeB, or home Node B, HNB), baseband unit (baseband unit, BBU), wireless fidelity ( wireless fidelity, Wi-Fi) system access point (access point, AP), wireless relay node, wireless backhaul node, transmission point (transmission and reception point, TRP or transmission point, TP), etc.; can also be 5G, such as gNB in new radio (NR) system, or transmission point (TRP or TP), one or a group (including multiple antenna panels) antenna panels of base station in 5G system, or, also It can be a network node that constitutes a gNB or a transmission point, such as a baseband unit (BBU), or a distributed unit (distributed unit, DU), a global navigation satellite system (global navigation satellite system, GNSS), etc. For example, RSU can identify vehicles, and can also integrate with 4G or 5G base stations to form a network. As a roadside communication unit, it can obtain road information (such as traffic light information, vehicle speed information) collected by roadside cameras and/or lidar and other devices. etc.), the RSU sends the road information to the first device 100 to implement V2X communication.

Exemplarily, the first device 100 can receive the V2X information sent by the second device 300, and determine the current vehicle driving condition by analyzing the V2X information. For example, the first device 100 receives the V2X information sent by the car A, determines that the car A is accelerating and approaching the own car, and sends notification information to the in-vehicle T-Box 201 through the connection with the vehicle. Further, as shown in FIG. 2 , the communication system may also include a vehicle machine (which can also be described as a vehicle-mounted terminal) 202. After receiving the notification message, the vehicle-mounted T-Box 201 sends prompt information to the vehicle machine 202, and utilizes the vehicle machine. 202 Display and/or voice broadcast prompt information to prompt the user to be careful with the vehicle A to avoid traffic accidents.

In some embodiments, the in-vehicle T-Box has been assembled in the vehicle during the vehicle assembly stage, and the subsequent user use stage only supports software upgrade of the in-vehicle T-Box but not hardware upgrade of the in-vehicle T-Box. However, the vehicle can only support the establishment of a V2X system if the vehicle-mounted T-Box in the vehicle supports the V2X function, and the vehicle-mounted T-Box needs to contain V2X corresponding protocol stacks, applications and hardware, and the vehicle-mounted T-Box may support the V2X function. Therefore, if the in-vehicle T-Box itself does not support the V2X function, the user cannot obtain this function by means of software upgrade during the use stage. Users can only give up the existing vehicles that do not support the V2X function, and choose to repurchase the vehicles that support the V2X function (that is, the vehicle's on-board T-Box supports the V2X function), which increases the user cost. In addition, there are currently fewer models equipped with in-vehicle T-Boxes that support the V2X function, and users can choose from a narrow range, which affects the user experience. Further, a large number of vehicles that do not support the V2X function lead to greater traffic pressure and a higher risk of traffic accidents.

FIG. 5 shows a schematic diagram of a V2X communication method provided by an embodiment of the present application. As shown in FIG. 5 , the method may include S501-S513:

S501. The first device obtains vehicle information.

In some embodiments, a vehicle application (application, APP) is installed in the first device, and the first device obtains vehicle information by using the vehicle APP. The vehicle information includes, for example, one or more items of vehicle model, license plate number, vehicle specification information, vehicle Wi-Fi information, vehicle internet protocol (IP) address information, and the like. The vehicle specification information includes, for example, specification information of the length, width, and height of the vehicle. The vehicle Wi-Fi information is used to represent the Wi-Fi network information provided by the vehicle, such as the name of the Wi-Fi network.

In some embodiments, the Wi-Fi network on the vehicle is provided by the in-vehicle T-Box, and after the first device enters the coverage of the Wi-Fi network provided by the in-vehicle T-Box, it can search for the service set identifier of the Wi-Fi network ( service set identifier, SSID). Among them, the SSID is generally the name of the Wi-Fi network, and the SSID is the unique identity document (ID) of different networks. The vehicle-mounted T-Box provides different SSIDs to distinguish the different networks it provides (such as 2.4GHz network). , 5GHz network, car owners access the network, passengers access the network, etc.), the first device can access the corresponding network after obtaining the SSID.

Exemplarily, as shown in the interface 601 in FIG. 6(a), after the first device (such as a mobile phone) detects that the user clicks on the vehicle control 61, the vehicle APP is opened, and the interface shown in FIG. 6(b) is displayed. 602. On the interface 602, the first device collects vehicle information. Optionally, the user may own multiple vehicles, and the vehicle APP can be used to manage multiple vehicles. As shown in interface 602, the first device is capable of managing the user's three vehicles (eg, vehicle A, vehicle B, and vehicle C). In addition, after the first device detects that the user clicks the operation of adding the control 63, it is also possible to add more vehicles for management. Afterwards, if the first device detects the user's operation of clicking on the control 62, the interface 603 shown in FIG. 6(c) is displayed, and the user's editing of the vehicle information of the vehicle A is received on the interface 603. For example, the first device receives one or more items of vehicle model, license plate number, vehicle Wi-Fi name, and vehicle specification information input by the user. For example, the first device receives the vehicle model input by the user, and can automatically match and fill in the vehicle specification information according to the vehicle model. For another example, the first device receives the vehicle Wi-Fi name input by the user, where the vehicle Wi-Fi name corresponds to the SSID of the Wi-Fi network provided by the in-vehicle T-Box. Or, the first device automatically matches the corresponding vehicle Wi-Fi network SSID list according to the received vehicle Wi-Fi name. Alternatively, the first device directly receives the vehicle Wi-Fi network SSID list sent by the vehicle. The vehicle Wi-Fi network SSID list includes at least one SSID of the Wi-Fi network provided by the vehicle T-Box.

In some embodiments, the first device may also collect vehicle information to determine whether the user allows the vehicle to send and receive V2X information through the first device. In the interface 603 shown in FIG. 6(c), the first device detects that the user clicks on the control 64, and determines whether the user enables or disables the V2X mode of the first device, that is, determines whether to allow the first device to transmit V2X information to the vehicle. If permitted, the vehicle can subsequently implement V2X communication using the first device; if not, the vehicle cannot subsequently implement V2X communication using the first device. As shown in interface 603, the current user allows vehicle A to send and receive V2X information through the mobile phone (i.e. the first device). Further, as shown in the interface 603 in FIG. 6(c), after the first device detects the operation of the user clicking the control 65, it determines that the user deletes the vehicle information of the vehicle A, that is, the first device can add or delete the vehicle information in response to the user operation. Managed vehicles.

S502, the first device establishes a communication connection with the vehicle.

Exemplarily, the IP packet communication manner between the first device and the vehicle is a wireless communication manner based on a Wi-Fi network. First, the first device needs to determine the SSID and authentication method of the Wi-Fi network to be accessed. Among them, in the current vehicle-provided Wi-Fi network scenario, the vehicle-mounted T-Box acts as a router, and the authentication method has been pre-configured in the vehicle-mounted T-Box. During the authentication process, the first device interacts with the vehicle-mounted T-Box. The identity authentication frame completes the authentication process. The first device may obtain the SSID in the scanning process, and the scanning process is divided into a passive scanning process and an active scanning process. For example, in the passive scanning process, the first device monitors a beacon (Beacon) frame sent by a vehicle-mounted T-Box near the first device according to a preset period, and obtains the SSID carried in the Beacon frame. For another example, the first device sends a probe request management frame to the vehicle-mounted T-Box, and then obtains the SSID after receiving the probe response management frame sent by the vehicle-mounted T-Box.

After that, based on the SSID and the authentication method, the first device is connected to the vehicle Wi-Fi network, the in-vehicle T-Box is used as an access point (AP), the first device is used as a station (station, STA), and the first device is connected to the vehicle Wi-Fi network. Wi-Fi connection is established between in-vehicle T-Boxes. Optionally, when the first device accesses the vehicle Wi-Fi network for the first time, it needs to detect the user's confirmation operation to confirm that the user allows access to the Wi-Fi network. Subsequently, after the first device enters the coverage of the Wi-Fi network of the same vehicle again, it is allowed to automatically access the Wi-Fi network of the vehicle.

In another example, the IP packet communication mode between the first device and the vehicle is a wired communication mode based on a USB interface connection. After the first device detects that the device is connected to the USB interface, it can confirm that the currently connected device is a vehicle. For example, the first device displays prompt information to prompt the user to determine the identity of the access device, and the user confirms that the current access device is a vehicle. For another example, the first device confirms that the access device is a vehicle by detecting whether the IP address of the access device is the vehicle IP address.

It can be understood that the IP packet communication connection between the first device and the vehicle may also be implemented in other ways, such as through Bluetooth communication, which is not specifically limited in this embodiment of the present application.

S503, the vehicle-mounted T-Box receives vehicle startup information.

S504, the vehicle-mounted T-Box sends vehicle startup information to the first device.

In some embodiments, in the above steps S503 and S504, after the vehicle ignition is started, the vehicle-mounted T-Box obtains the vehicle ignition information, determines that the vehicle has been started, and sends the vehicle start information to the first device. Correspondingly, after receiving the vehicle start information, the first device determines that the vehicle has started.

S505. The first device determines that the communication connection address is the target address, and starts the driving mode.

In some embodiments, after receiving the vehicle startup information, the first device determines whether to establish a communication connection with the vehicle. For example, it is determined whether the current communication address is the target address, and then it is determined whether IP packet communication with the vehicle can be performed at present. After it is determined that IP packet communication with the vehicle is possible, the driving mode is activated. For example, referring to the above-mentioned step S502, an IP packet communication connection may be established between the first device and the vehicle through a Wi-Fi network or USB or the like. Wherein, the target address includes, for example, a target SSID, a target IP address, and the like for accessing the Wi-Fi network. The target SSID is at least one SSID in the SSID of the Wi-Fi network of the vehicle, and the target IP address is the IP address corresponding to the USB interface of the vehicle.

In some embodiments, after receiving the vehicle startup information, the first device determines that it has connected to the Wi-Fi network, and determines that the SSID of the Wi-Fi network accessed is in the preset SSID list of the vehicle Wi-Fi network The SSID of the vehicle is determined (that is, the address of the communication connection with the vehicle is determined as the target address), and then it is determined that the current first device has been connected to the vehicle Wi-Fi network, and the vehicle state can be monitored. After that, the driving mode is activated.

In some embodiments, the first device may be connected to the Wi-Fi network provided by the in-vehicle T-Box of multiple vehicles, and multiple devices may be connected to the Wi-Fi network provided by the in-vehicle T-Box of one vehicle. Therefore, the first device needs to determine whether the SSID of the currently accessed Wi-Fi network is the target SSID corresponding to the vehicle owner's access network, and then start the driving mode after determining that the SSID is the target SSID. That is to ensure that the owner of the first device and the owner of the vehicle are the same user, and then it can be ensured that the vehicle-mounted T-Box can only send the vehicle status information to one first device, and one first device is used as the vehicle's external V2X module. V2X information to avoid abnormal V2X information transmission. Optionally, in the process of accessing the Wi-Fi network, the first device may receive a user operation, and after determining that the current vehicle is the owner of the first device as the vehicle of the owner, access the Wi-Fi network corresponding to the target SSID. The owner is connected to the network. For example, in the interface 602 shown in FIG. 6(b), the first device determines that the vehicle currently providing the Wi-Fi network to be accessed is the host vehicle, and then accesses the network with the same SSID as the vehicle Wi-Fi name. Subsequently, the first device determines, according to the SSID, whether to receive the vehicle state information as the vehicle owner device.

In other embodiments, the number of the first devices is one or more, and the first device determines that the SSID of the Wi-Fi network to be accessed is any one of the SSIDs of the Wi-Fi network provided by the in-vehicle T-Box, then Activate driving mode. Subsequently, the vehicle uses one or more first devices as an external V2X module of the vehicle to transmit V2X information, expand the coverage of the V2X system, and improve the accuracy of V2X information.

In other embodiments, after receiving the vehicle startup information, the first device determines that the IP address of the device with which the USB connection is established is the target IP address, and determines that an IP packet communication link has been established with the vehicle. Further, subsequently, the first device can transmit the IP packet carrying the vehicle status information with the vehicle based on the link, so as to realize the V2X communication of the vehicle.

In some embodiments, after the first device determines that the communication connection address is the target address, it needs to determine whether the vehicle information contains information about whether the user allows the first device to send and receive V2X information, as shown in the interface 603 in FIG. 6(c), The first device determines that the user allows the vehicle to send and receive V2X information through the first device, and then starts the driving mode. Optionally, if the vehicle information does not include information on whether the vehicle is allowed to send and receive V2X information through the first device, the user is prompted to confirm through a prompt message, and the driving mode is started after confirming the user's permission, and the P2X mode is switched to the V2X mode. Alternatively, the vehicle information includes information on whether the user allows the first device to send and receive V2X information, and the first device also displays prompt information to prompt the user to perform a second confirmation to avoid abnormalities caused by misoperation. As shown in the interface 701 in FIG. 7 , the first device displays prompt information 71, and in response to the user operation, confirms whether the user is allowed to switch the V2X mode.

In some embodiments, the first device turns on or off the V2X mode after detecting the user's preset operation. Exemplarily, as shown in the main interface 801 in FIG. 8( a ), after the first device detects the operation of the user clicking on the control 81 , the first device displays the setting interface 802 shown in FIG. 8( b ). On the device interface 802, after the first device detects that the user clicks on the control 82, an interface 803 as shown in (c) of FIG. 8 is displayed. The connection status of the first device is set on the interface 803. For example, after detecting the operation of the user clicking on the control 83, the interface 804 shown in (d) of FIG. 8 is displayed. On the interface 804, in response to the operation of the user clicking the control 84 or the control 85, the first device switches the P2X mode or the V2X mode. For example, in step S505, the first device starts the driving mode, and after the V2X mode is turned on, the first device detects the user's preset operation, turns off the V2X mode, and automatically switches the V2X mode to the P2X mode. Alternatively, the first device directly starts the driving mode after detecting the user's operation of turning on the V2X mode. Optionally, the P2X mode and the V2X mode shown in the interface 804 will not be enabled at the same time.

In some scenarios, after the first device establishes a communication connection with the vehicle, prompt information is displayed to prompt the user whether to switch the V2X mode. If it is detected that the user allows the operation of switching the V2X mode, the P2X mode is switched to the V2X mode (that is, the driving mode is activated). That is, after the first device performs the above step S502, the steps S503 and S504 are no longer performed, and the user directly determines whether to activate the driving mode in the step S505. Therefore, after the first device is communicatively connected to the vehicle, even if the vehicle is not started (that is, the vehicle has not been fired and started for the time being), V2X communication with other things can be achieved. If a nearby vehicle is prompted, there is a vehicle parked at the current location, pay attention to avoid it.

S506, the vehicle-mounted T-Box obtains vehicle status information.

In some embodiments, the vehicle-mounted T-Box is located in a controller area network (CAN) in the vehicle, and uses the CAN bus to obtain vehicle status information detected by various modules in the vehicle. The vehicle status information includes, for example, information such as vehicle four-axis acceleration, braking system status, and vehicle lamp status. The CAN bus system includes, for example, a CAN controller, an information transceiver, a data transmission terminal, and a data transmission bus (which can also be described as a CAN bus). CAN bus is one of the most widely used field buses in the world, which can realize reliable communication between electronic control units (ECUs) in vehicles. After the vehicle is started, the CAN bus is activated, and the on-board T-Box uses the CAN bus to obtain information such as control, temperature, and rotational speed broadcast by each ECU in the vehicle to determine vehicle status information.

S507. The vehicle-mounted T-Box sends vehicle status information to the first device.

In some embodiments, after obtaining the vehicle status information, the vehicle-mounted T-Box determines to send the vehicle status information to the external V2X module (ie, the first device).

S508. The first device generates V2X information according to the vehicle state information.

In some embodiments, the first device receives the vehicle status information sent by the vehicle-mounted T-Box, and assembles the V2X information based on a standard protocol according to the vehicle status information, its own location information, and vehicle information (such as vehicle model information, vehicle specification information, etc.). . The vehicle location information may be the location information of the current vehicle determined by the first device or the vehicle using, for example, a global navigation satellite system (GNSS) or a global positioning system (global positioning system, GPS). Standard protocols include, for example, V2X protocols, V2V protocols, and the like. V2X messages include, for example, basic safety messages (BSMs) and other event-type messages. For example, the BSM includes information such as the speed, steering, braking, double flash, and position of the vehicle. BSM is mostly used in V2V scenarios, such as lane change warning, blind spot warning, intersection collision warning and other scenarios. Event-type messages are used to indicate the event information directly sent during vehicle event warning, such as lane change warning information.

S509, the first device and the second device exchange V2X information.

In some embodiments, after the first device generates the V2X information, it broadcasts the V2X information, and other nearby devices can receive the V2X information broadcast by the first device. In addition, the first device can receive V2X information sent by a second device in the V2X system, such as other vehicles, so as to realize interactive V2X information.

In some embodiments, the first device broadcasts the V2X information after generating the V2X information based on the vehicle-related operation information sent by the vehicle machine or the T-Box to the first device. The above-mentioned vehicle-related operating information may be, for example, vehicle position, vehicle speed, vehicle heading, vehicle lamp status, vehicle engine status, and the like.

S510. The first device determines alarm information according to the received V2X information sent by the second device.

In some embodiments, after receiving the V2X information, the first device parses the V2X information to determine the current alarm information. Among them, the warning information is used to indicate the information that the vehicle needs to give an early warning during the driving process, such as information about other vehicles entering the current driving road, information on continuous curves, other vehicles approaching at high speed, red lights ahead, congestion on the road ahead and other information.

S511. The first device sends alarm information to the vehicle-mounted T-Box.

In some embodiments, after determining the alarm information, the first device sends the alarm information to the in-vehicle T-Box, thereby realizing effective V2X information interaction with the vehicle during the driving process of the vehicle.

S512 , the in-vehicle T-Box sends alarm information to the in-vehicle machine.

S513 , the vehicle machine broadcasts and/or displays alarm information.

Exemplarily, it is assumed that the current scene is that other vehicles are accelerating close to the own vehicle. As shown in the vehicle-machine interface 901 shown in FIG. 9A , after receiving the warning information, the vehicle-machine displays the warning information 91 , such as “Currently a vehicle is accelerating and approaching, please pay attention to avoid it”. At the same time, the car machine can also voice broadcast the current alarm information to avoid danger because the user does not notice the displayed alarm information.

In some embodiments, the display mode of the alarm information may be text display, image display, video display, or the like. For example, the vehicle detects that the driver has turned on the left turn signal, and determines that the current vehicle is ready to overtake, but it is assumed that there is a large truck in front of the road on which the current vehicle is driving, which blocks the driver's sight and cannot observe the oncoming vehicle on the opposite side. The in-vehicle T-Box sends the vehicle status information (that is, the left turn signal on information) to the first device, and the first device interacts with other vehicles in V2X information to determine that there is a large truck driving in front of the vehicle, and another vehicle is driving on the opposite side. car, it is determined that overtaking is more dangerous at this time. The first device sends an alarm message to the on-board T-Box, and after receiving the alert message forwarded by the on-board T-Box, the car machine displays the alert message such as "There is an approaching vehicle ahead, please do not overtake"; and/or, voice broadcast "There is an approaching vehicle ahead" and/or, as shown in the vehicle-machine interface 902 shown in FIG. 9B, the current scene image 92 is displayed to warn the driver of the danger of the current overtaking operation. In this way, traffic accidents can be avoided when the driver fails to perceive the danger because the vehicle does not support V2X technology and cannot communicate with other vehicles in V2X.

In some scenarios, if there are multiple vehicles near the first device, the first device can determine whether to establish a communication connection with one or more of the vehicles according to preset conditions, as an external V2X module of the vehicle. The preset conditions include, for example, that vehicle information is stored in the first device, the distance between the first device and the vehicle is less than or equal to a preset threshold, and the communication quality between the first device and the vehicle satisfies the preset conditions (for example, the packet loss rate is less than or equal to or equal to a preset packet loss rate threshold, etc.), the number of vehicles connected to the first device is less than or equal to one or more of the allowable preset number, etc.

Exemplarily, the preset condition includes that vehicle information is stored in the first device, and the first device obtains the vehicle information of vehicle A, vehicle B, and vehicle C by using the vehicle APP, then the first device is allowed to communicate with vehicle A, vehicle B, and vehicle C. Establish a wireless communication connection. Based on the above situation, if the preset conditions further include that the preset number of vehicles allowed for the first device to be connected is 1, it can be determined by judging the distance and/or communication quality between the first device and vehicle A, vehicle B and vehicle C. Which vehicle to establish a wireless communication connection with. For example, the distance between the first device and the vehicle is determined by using an ultra wide band (ultra wide band, UWB) positioning technology, GNSS technology, GPS technology, etc., and/or the communication quality is determined by using Wi-Fi signal strength, Bluetooth signal strength, and the like. For example, the first device determines to establish a wireless communication connection with the closest vehicle A to it. After that, when the communication distance changes, the first device automatically determines to disconnect the wireless communication connection with the vehicle A, and switches to establish the wireless communication connection with the vehicle B.

In this way, a vehicle equipped with an in-vehicle T-Box that does not support V2X can use electronic equipment to realize V2X communication without increasing the hardware cost, improving driving safety and communication efficiency.

In some scenarios, in the above steps S510 and 511, after receiving the V2X information sent by the second device, the first device can also directly send the V2X information to the vehicle-mounted T-Box, and the vehicle-mounted T-Box generates the V2X information according to the V2X information. Warning information. Also, the vehicle without the V2X communication function can realize the interaction of V2X information, and the power consumption of the processor of the first device can be reduced, and the power consumption can be reduced.

In some scenarios, the first device can also establish connections with other ECUs in the vehicle, receive vehicle status information sent by other ECUs to generate V2X information, and send alarm information to the corresponding ECUs. For this, please refer to the above-mentioned first device and vehicle-mounted The related content of T-Box interaction will not be repeated here.

In some scenarios, the vehicle has an automatic driving function, and after receiving the alarm information, the on-board T-Box can also send the alarm information to the automatic driving control module, so as to realize the vehicle adaptive change of the current vehicle driving strategy. Exemplarily, FIG. 10 shows a schematic diagram of another V2X communication method provided by this embodiment of the present application. Based on the V2X communication method shown in FIG. 5 , as shown in FIG. 10 , the V2X communication method may further include steps S1001 and S1002. .

S1001, the vehicle-mounted T-Box sends alarm information to the automatic driving control module.

In some embodiments, if the vehicle has an automatic driving function, after receiving the warning information, the vehicle-mounted T-Box sends the warning information to the automatic driving control module. Correspondingly, the automatic driving control module receives the alarm information sent by the vehicle-mounted T-Box.

S1002, the automatic driving control module automatically adjusts the driving strategy based on the warning information.

In some embodiments, the autonomous driving system in the vehicle can assist the vehicle to achieve the following functions: perception (such as assisted perception and over-the-horizon perception, etc.), high-precision positioning (such as determining the location of the vehicle on the map, etc.), decision-making ( Such as lane-level path planning) and control (steering wheel control, acceleration and deceleration control, braking control, etc.). Among them, the automatic driving control module, as the central decision-making module in the automatic driving system, is used to receive the information sent by various modules in the automatic driving system (such as vehicle T-Box, sensors, cameras, etc.), and determine the driving strategy based on the received information. And send the driving strategy to the corresponding module for execution to realize the automatic driving of the vehicle.

Exemplarily, it is assumed that a vehicle breaks down in front of the vehicle while the vehicle is driving. As described in steps S509 to S511 above, after detecting the abnormality, the first device sends the alarm information to the vehicle-mounted T-Box. After that, as shown in Figure 10, the vehicle-mounted T-Box sends the received warning information to the automatic driving control module. After receiving the warning information, the automatic driving control module determines the current abnormal situation according to the warning information, and determines that the driving strategy needs to be adjusted. For example, the original straight driving strategy is automatically adjusted to the driving strategy of decelerating and changing lanes, and the adjusted driving strategy is sent to the relevant module to avoid collision with the broken down vehicle.

In other scenarios, after monitoring the abnormal situation, the first device can directly send the abnormal situation (that is, the alarm information) to the automatic driving control module of the vehicle, that is, it does not need to be forwarded by the on-board T-Box, improving the automatic driving vehicle. Adjust the efficiency of your driving strategy.

In this way, an autonomous vehicle equipped with an in-vehicle T-Box that does not support V2X communication can also use the first device as an external V2X module to realize V2X communication and improve driving safety and communication efficiency.

In some embodiments, in the method flow shown in FIG. 10 , after receiving the warning information, the vehicle-mounted T-Box may send the warning information to the automatic driving control module, but not send the warning information to the vehicle machine (that is, the above-mentioned Step S512). After that, after receiving the warning information, the automatic driving control module automatically adjusts the driving strategy and sends the warning information and adjustment results to the vehicle. For example, in the above-mentioned vehicle automatic lane change scenario, based on the received information, the vehicle and the machine display "there is a breakdown vehicle ahead, which has automatically decelerated and changed lanes". Alternatively, after receiving the warning information and automatically adjusting the driving strategy, the automatic driving control module does not send the warning information and the adjustment result to the vehicle, that is, the driving strategy adjustment without the user's perception is realized.

It should be noted that, this embodiment of the present application does not specifically limit the execution order of the foregoing steps S512 and S1001. For example, after receiving the warning information, the vehicle-mounted T-Box first sends the warning information to the vehicle to warn the driver, and then sends the warning information to the automatic driving control module to change the automatic driving mode. For another example, after receiving the alarm information, the vehicle-mounted T-Box first sends the alarm information to the automatic driving control module, and then sends the alarm information to the vehicle. For another example, after receiving the alarm information, the vehicle-mounted T-Box sends the alarm information to the vehicle machine and the automatic driving control module at the same time.

In some scenarios, if the vehicle is not started, the first device does not need to perform V2X information transmission. Based on this, after determining that the vehicle is turned off, the first device can automatically turn off the driving mode. Exemplarily, FIG. 11 shows a schematic diagram of another V2X communication method provided by this embodiment of the present application. Based on the V2X communication method shown in FIG. 5 , as shown in FIG. 11 , after the above step S513, the V2X communication method can also be used. It includes steps S1101-S1103.

S1101. The vehicle-mounted T-Box receives vehicle shutdown information.

S1102. The vehicle-mounted T-Box sends vehicle shutdown information to the first device.

In some embodiments, in the above steps S1101 and S1102, after the vehicle is turned off, the vehicle-mounted T-Box obtains the vehicle shutdown information, determines that the vehicle has been turned off, and sends the vehicle shutdown information to the first device. Correspondingly, the first device receives the vehicle shutdown information, and determines that the vehicle has been turned off.

S1103. The first device turns off the driving mode.

In other embodiments, after detecting the user's operation of turning off the V2X mode, the first device turns off the driving mode, and switches the V2X mode to the P2X mode. Exemplarily, as shown in the interface 804 in (d) of FIG. 8 , after detecting the user's operation of clicking the control 85, the first device turns off the V2X mode, that is, turns off the driving mode.

It should be noted that, the above steps S1101 to S1103 may also be executed after step S1002 in the flowchart shown in FIG. 10 . That is, a vehicle with an automatic driving function can also send the vehicle shutdown information to the first device after the ignition is turned off, so as to instruct the first device to automatically switch the V2X mode.

In this way, the first device can automatically switch the V2X mode based on the vehicle startup or shutdown information, realize the mode switching without the user's perception, and improve the user experience.

In some scenarios, the first device and the vehicle use mirror link, Miracast standard or

and other standards for interconnection, in the above step S510, after determining the alarm information, the first device can directly send the alarm information to the vehicle. Exemplarily, FIG. 12 shows a schematic diagram of another V2X communication method provided by an embodiment of the present application. Based on the V2X communication method shown in FIG. 5 , as shown in FIG. 12 , after the above step S510, the first device no longer The above-mentioned steps S511 to S513 are performed, but the following steps S1201 and S1202 are performed instead.

S1201. The first device sends alarm information to the vehicle.

S1202, the vehicle machine broadcasts and/or displays warning information.

In some embodiments, in the above steps S1201 and S1202, after determining the alarm information, the first device determines that a connection with the vehicle has been established, and based on the connection relationship, directly sends the alarm information to the vehicle for broadcast and/or or display.

It should be noted that, steps S511 to S513 in the flowchart shown in FIG. 10 can also be replaced with the above-mentioned steps S1201 and S1202. That is, a vehicle with an automatic driving function can also directly receive the alarm information sent by the first device with the vehicle machine configured in the vehicle.

In this way, based on the direct connection between the first device and the vehicle, it is no longer necessary to forward the alarm information by the vehicle-mounted T-Box, which improves the efficiency of V2X communication and further improves driving safety.

In other scenarios, after determining the alarm information, the first device may directly use its own audio module to broadcast the alarm information, and/or use the display screen to display the alarm information.

In this way, after determining the current vehicle driving danger, the first device can directly perform an early warning, so as to avoid abnormal early warning caused by a communication problem with the on-board T-Box or the on-board machine.
