[0045] The vehicle-mounted terminal 101 is a terminal installed on the vehicle, and is used to collect vehicle query information, send messages or receive messages, wherein the vehicle query information is used to determine the target of the message. The vehicle-mounted terminal 101 is connected to the server 104 via a wireless network, and the vehicle-mounted terminal 101 can exchange data with the server 104. In the embodiment of the present application, the vehicle-mounted terminal 101 can be either the vehicle-mounted terminal of the first vehicle or the vehicle-mounted terminal of the second vehicle, and the embodiment of the present application does not limit this.

[0046] The server 104 is connected to the cloud platform 103 via a wired network or a wireless network. The server 104 is an independent physical server, or a server cluster or distributed system composed of multiple physical servers, or a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, distribution networks, and big data and artificial intelligence platforms. The server 104 can obtain messages and vehicle query information from the vehicle terminal 101, and can also send messages to the vehicle terminal 101.

[0047] After introducing the implementation environment of the embodiment of the present application, the application scenario of the technical solution provided by the embodiment of the present application is introduced below. The technical solution provided by the embodiment of the present application can be applied to various vehicles with vehicle-mounted terminals. For example, the technical solution provided by the embodiment of the present application can be applied to electric vehicles, hybrid vehicles, and fuel vehicles, and the embodiment of the present application does not limit this.

[0048] After adopting the technical solution provided in the embodiment of the present application, the server obtains the target message sent by the first vehicle and the vehicle query information corresponding to the target message, and the vehicle query information includes at least one vehicle identification recognized by the first vehicle or the vehicle position of the first vehicle. The server performs a vehicle query based on the vehicle query information to obtain at least one second vehicle, and the at least one second vehicle refers to the vehicle indicated by the at least one vehicle identification, or a vehicle whose position is related to the vehicle position of the first vehicle. The server sends the target message to the at least one second vehicle so that the at least one second vehicle displays the target message. The first vehicle and the second vehicle can transmit messages in the above manner, thereby enriching the method of message transmission between vehicles.

[0049] After introducing the implementation environment and application scenarios of the embodiments of the present application, the message sending method provided by the embodiments of the present application is described below. Figure 2 Taking the execution subject as the first vehicle as an example, the method includes the following steps.

[0050] 201. In response to an instruction to send a target message, a first vehicle obtains vehicle query information corresponding to the target message, where the vehicle query information includes at least one vehicle identification recognized by the first vehicle or a vehicle position of the first vehicle.

[0051] Among them, the target message is a message that needs to be transmitted between vehicles. The target message can be configured by the user of the first vehicle or automatically generated by the first vehicle, and the embodiments of the present application do not limit this. The first vehicle is the sender of the target message, and the first vehicle is any type of vehicle. The vehicle query information is used to determine the recipient of the target message, that is, to query the vehicle that receives the target message. The vehicle identification, as the unique identification of the vehicle, can directly identify the vehicle. In some embodiments, the vehicle identification refers to the license plate number. The vehicle position refers to the position of the first vehicle when the sending instruction is triggered, and the vehicle can be indirectly determined based on the vehicle position.

[0052] 202. The first vehicle sends the target message and vehicle query information corresponding to the target message to the server, so that the server forwards the target message to at least one second vehicle corresponding to the vehicle query information.

[0053] The server has a message sending function. After the first vehicle sends the target message and the vehicle query information to the server, the server can send the target message to the second vehicle corresponding to the vehicle query information, thereby realizing message transmission between the first vehicle and at least one second vehicle. The second vehicle is the recipient of the message, and the second vehicle is any type of vehicle.

[0054] Through the technical solution provided by the embodiment of the present application, in response to the instruction to send the target message, the first vehicle obtains the vehicle query information corresponding to the target message, and the vehicle query information includes at least one vehicle identification recognized by the first vehicle or the vehicle position of the first vehicle. The first vehicle sends the target message and the vehicle query information to the server, so that the server sends the target message to at least one second vehicle corresponding to the vehicle query information, thereby realizing the message transmission between the first vehicle and the at least one second vehicle, and enriching the message transmission mode between vehicles.

[0055] Another message sending method provided in the embodiment of the present application is described below. Figure 3 Taking the execution subject as a server as an example, the method includes the following steps.

[0056] 301. A server obtains a target message sent by a first vehicle and vehicle query information corresponding to the target message, where the vehicle query information includes at least one vehicle identification recognized by the first vehicle or a vehicle position of the first vehicle.

[0057] The target message is a message that needs to be transmitted between vehicles. The target message can be configured by a user of the first vehicle or automatically generated by the first vehicle, which is not limited in the embodiment of the present application. The first vehicle is the sender of the target message, and the first vehicle is any type of vehicle. The vehicle query information is used to determine the recipient of the target message, that is, the vehicle that receives the target message.

[0058] 302. The server performs a vehicle query based on the vehicle query information to obtain at least one second vehicle.

[0059] The at least one second vehicle is a recipient of the message, and the second vehicle is any type of vehicle.

[0060] 303. The server forwards the target message to the at least one second vehicle, so that the at least one second vehicle displays the target message.

[0061] Through the technical solution provided in the embodiment of the present application, the server obtains the target message sent by the first vehicle and the vehicle query information corresponding to the target message, and the vehicle query information includes at least one vehicle identification recognized by the first vehicle or the vehicle position of the first vehicle. The server performs a vehicle query based on the vehicle query information and obtains at least one second vehicle, and the at least one second vehicle is also the recipient of the target message. The server sends the target message to the at least one second vehicle so that the second vehicle displays the target message, thereby realizing the message transmission between the first vehicle and the at least one second vehicle, enriching the message transmission method between vehicles.

[0062] It should be noted that the above steps 201-202 and 301-303 are a simple description of the message sending method provided in the embodiment of the present application. The message sending method provided in the embodiment of the present application will be described in more detail below with reference to some examples. Figure 4 , the method comprises the following steps.

[0063] 401. In response to an instruction to send a target message, a first vehicle obtains vehicle query information corresponding to the target message, where the vehicle query information includes at least one vehicle identification recognized by the first vehicle or a vehicle position of the first vehicle.

[0064] Among them, the target message is a message that needs to be transmitted between vehicles. The target message can be configured by the user of the first vehicle or automatically generated by the first vehicle, and the embodiment of the present application does not limit this. The sending instruction of the target message is used to instruct the first vehicle to send the target message. Correspondingly, the first vehicle is the sender of the target message. The first vehicle is any type of vehicle, such as an electric vehicle, a hybrid vehicle or a fuel vehicle. The embodiment of the present application does not limit this. The vehicle query information is used to determine the recipient of the target message, that is, to query the vehicle that receives the target message. The vehicle identification, as the unique identification of the vehicle, can directly identify the vehicle. In some embodiments, the vehicle identification refers to the license plate number. The vehicle position refers to the position of the first vehicle when the sending instruction is triggered, and the vehicle can be indirectly determined based on the vehicle position.

[0065] In a possible implementation, in response to a sending instruction for a target message, the first vehicle determines a message type of the target message, where the message type is used to indicate the urgency of the target message, and obtains the vehicle query information in an information acquisition manner corresponding to the message type of the target message.

[0066] The vehicle query information includes the vehicle identification or the vehicle location. Different message types correspond to different vehicle query information. Since the message type is used to indicate the urgency of the target message, different urgency levels correspond to different vehicle query information. In addition, different vehicle query information corresponds to different information acquisition methods. Therefore, determining the message type of the target message can also determine the information acquisition method for acquiring the vehicle query information.

[0067] In this implementation, in response to the instruction to send the target message, the first vehicle determines the urgency of the target message, that is, determines the message type of the target message. The first vehicle obtains the vehicle query information in an information acquisition method corresponding to the message type, so that the obtained vehicle query information is more compatible with the message type of the target message.

[0068] In order to explain the above implementation more clearly, the above implementation will be explained in two parts below.

[0069] Part 1: In response to a sending instruction for a target message, the first vehicle determines a message type of the target message.

[0070] In one possible implementation, in response to an instruction to send a target message, the on-board terminal of the first vehicle obtains the message type of the target message from a message queue storing the target message, where the message type is determined when the target message is generated. The message queue is used to store messages to be sent and message types of messages.

[0071] In this implementation mode, the message type of the target message can be obtained from the message queue, and the acquisition efficiency of the message type is high.

[0072] In a possible implementation, in response to an instruction to send a target message, the on-board terminal of the first vehicle obtains a message type of the target message from the target message, where the message type is carried in the target message.

[0073] In this implementation, the message type of the target message can be directly obtained from the target message, which is highly efficient.

[0074] Part 2: The first vehicle obtains the vehicle query information in an information acquisition manner corresponding to the message type of the target message.

[0075] In a possible implementation, when the target message type is a common message or an important message, the first vehicle acquires vehicle images around the first vehicle, performs image recognition on the vehicle images, and obtains at least one vehicle identification, and the urgency of the important message is greater than that of the common message.

[0076] Among them, the image around the first vehicle is acquired by an image acquisition device installed around the first vehicle. In some embodiments, the image acquisition device is a camera, and the camera is installed around the first vehicle (front, rear, left, and right). The vehicle image refers to an environmental image including the vehicle, and the number of vehicles included in the vehicle image is one or more. Ordinary messages are messages with a lower degree of urgency, and important messages are messages with a higher degree of urgency than ordinary messages. For example, an ordinary message is "Newbie, please keep a safe distance", and an important message is "There is a wounded person in the vehicle, please give way". Of course, the content of the above ordinary messages and important messages is only an example. The content of ordinary messages and important messages can be set by the driver according to actual conditions, and the embodiments of the present application do not limit this.

[0077] In this implementation manner, when the target message type is a common message or an important message, a vehicle image around the first vehicle is obtained. Image recognition is performed on the vehicle image to obtain at least one vehicle identification, which is also the vehicle query information corresponding to the target message. The vehicles around the first vehicle can be queried through the vehicle query information, and the target message can be subsequently sent to the vehicles around the first vehicle.

[0078] For example, when the target message type is a common message or an important message, the vehicle terminal of the first vehicle acquires vehicle images around the first vehicle through an image acquisition device, and the number of the vehicle images is one or more. The vehicle terminal of the first vehicle inputs the vehicle image into a vehicle identification recognition model, extracts features of the vehicle image through the vehicle identification recognition model, and obtains image features of the vehicle image. The vehicle terminal of the first vehicle maps the image features of the vehicle image through the vehicle identification recognition model, and obtains at least one vehicle identification corresponding to the vehicle image.

[0079] The vehicle identification recognition model is trained based on sample vehicle images and the annotated vehicle identifications corresponding to the sample vehicle images, and has the ability to determine the vehicle identification based on the vehicle images.

[0080] For example, the vehicle identification refers to the vehicle's license plate number, and accordingly, the vehicle identification recognition model refers to the license plate number recognition model. When the message type of the target message is a normal message or an important message, the on-board terminal of the first vehicle obtains vehicle images around the first vehicle through a camera. The on-board terminal of the first vehicle inputs the vehicle image into the license plate number recognition model, performs target recognition on the vehicle image through the license plate number recognition model, and obtains a license plate sub-image in the vehicle image. The on-board terminal of the first vehicle uses the license plate number recognition model to perform at least one full connection, at least one convolution, or attention encoding on the license plate sub-image to obtain the image features of the license plate sub-image. The on-board terminal of the first vehicle uses the license plate number recognition model to fully connect and normalize the image features of the license plate sub-image to obtain at least one license plate number corresponding to the vehicle image.

[0081] In a possible implementation, when the message type of the target message is an emergency message, the first vehicle obtains the vehicle position of the first vehicle, and the urgency of the emergency message is greater than that of the important message.

[0082] The vehicle position is the current vehicle position of the first vehicle, and the vehicle position of the first vehicle is obtained by a positioning device installed on the first vehicle. An emergency message is a message of high urgency, for example, an emergency message is "the vehicle has a breakdown, please pay attention".

[0083] Under this implementation, when the message type of the target message is an emergency message, the vehicle position of the first vehicle is obtained, and the vehicle position is also the vehicle query information corresponding to the target message. Through the vehicle query information, vehicles in a larger range around the first vehicle can be queried, and the target message can be subsequently sent to the corresponding vehicle to realize message transmission between vehicles.

[0084] For example, when the message type of the target message is an emergency message, the vehicle terminal of the first vehicle obtains the vehicle position of the first vehicle through the vehicle positioning device, wherein the vehicle position is the coordinates of the first vehicle.

[0085] In some embodiments, the target message also carries a vehicle identification of the first vehicle, and the source of the target message can be identified through the vehicle identification.

[0086] The following describes the method of triggering the sending instruction in the above implementation mode.

[0087] In a possible implementation manner, in response to a message sending operation, the first vehicle triggers the sending instruction.

[0088] Among them, the message sending operation is an operation on the first vehicle. The message sending operation can refer to an operation on the central control screen / co-pilot screen of the first vehicle, or can refer to an operation on a physical button on the first vehicle. The embodiment of the present application does not limit this.

[0089] In this embodiment, the sending instruction can be triggered by an operation on the first vehicle, and the triggering timing of the sending instruction is more flexible.

[0090] The above implementation is described below through several examples.

[0091] Example 1: A message sending control is displayed on the central control screen of the first vehicle. In response to a click operation on the message sending control, the vehicle-mounted terminal of the first vehicle triggers the sending instruction.

[0092] For example, a message sending control is displayed on the central control screen / co-pilot screen of the first vehicle. In response to a click operation on the message sending control, the vehicle-mounted terminal of the first vehicle displays a message input interface on the central control screen / co-pilot screen, and the message input interface is used to input a message. In response to a confirmation operation on the target message on the message input interface, the vehicle-mounted terminal of the first vehicle triggers the sending instruction, and the target message is the message input on the message input interface. In some embodiments, in addition to being used to input a message, the message input interface is also used to select a message type.

[0093] Alternatively, there are multiple message sending controls, each of which corresponds to a preset message. The correspondence between the message sending controls and the preset messages is set and adjusted by a technician or user according to actual conditions, and the embodiments of the present application do not limit this. In response to a click operation on any of the multiple message sending controls, the vehicle-mounted terminal of the first vehicle triggers the sending instruction, and the preset message corresponding to the message sending control is also the target message. The message type of the preset message is set and adjusted by a technician or user according to actual conditions, and the embodiments of the present application do not limit this.

[0094] Example 2: The first vehicle includes a target button for sending a message to other vehicles. In response to a click operation on the target button, the vehicle-mounted terminal of the first vehicle triggers the sending instruction.

[0095] The target button can be set on the steering wheel lever of the first vehicle or on the center console of the first vehicle, which is not limited in the embodiment of the present application. The message corresponding to the target button is the target message. Of course, the message corresponding to the target button is set and adjusted by the technician or the user according to the actual situation, which is not limited in the embodiment of the present application.

[0096] For example, the first vehicle includes a target button for sending a message to another vehicle. In response to a click operation on the target button, the vehicle-mounted terminal of the first vehicle determines whether the target button is configured with a corresponding message. If the target button is configured with a corresponding message, the vehicle-mounted terminal of the first vehicle triggers the sending instruction.

[0097] In a possible implementation manner, when the first vehicle breaks down, the first vehicle triggers the sending instruction.

[0098] The failure of the first vehicle includes a failure of the power system, the braking system or the steering system of the first vehicle. In this implementation, the target message is used to notify the first vehicle of a failure, and the message type of the target message is an emergency message. For example, the emergency stop of the first vehicle in the middle of the road also indicates that the first vehicle has a failure. When it is detected that the first vehicle is stationary and in the middle of the road, it is determined that the first vehicle has a failure.

[0099] In this implementation, when the first vehicle breaks down, the sending instruction can be automatically triggered to send the target message to other vehicles to alert the first vehicle of the breakdown, thereby improving driving safety.

[0100] For example, when the first vehicle fails, the vehicle-mounted terminal of the first vehicle determines the component of the first vehicle that fails. The vehicle-mounted terminal of the first vehicle generates a target message corresponding to the component and triggers the sending instruction, the target message is used to indicate that the component fails, and the component is a power system, a braking system, or a steering system.

[0101] Optionally, before step 401 , the first vehicle can also perform the following steps.

[0102] In a possible implementation, the first vehicle sends a registration request to the server, the registration request carries the vehicle identification of the first vehicle, and the registration request is used to request to register a message sending function on the server. When receiving a registration success message returned by the server, the first vehicle can use the message sending function provided by the server to send messages to other vehicles.

[0103] 402. The first vehicle sends the target message and vehicle query information corresponding to the target message to the server.

[0104] In a possible implementation manner, the on-board terminal of the first vehicle sends the target message and the vehicle query information corresponding to the target message to the server through a wireless network.

[0105] For example, the vehicle-mounted terminal of the first vehicle encrypts the target message and the vehicle query information corresponding to the target message in a preset encryption method to obtain first encrypted information. The vehicle-mounted terminal of the first vehicle sends the first encrypted information to the server via a wireless network.

[0106] Among them, the preset encryption method is an encryption method agreed upon by the vehicle terminal and the server. The preset encryption method is set by technical personnel according to actual conditions, and the embodiments of the present application do not limit this.

[0107] For example, the vehicle-mounted terminal of the first vehicle uses the private key of the vehicle-mounted terminal and the public key of the server to encrypt the target message and the vehicle query information corresponding to the target message to obtain the first encrypted information. The vehicle-mounted terminal of the first vehicle sends the first encrypted information to the server via the wireless network.

[0108] 403. The server obtains the target message sent by the first vehicle and the vehicle query information corresponding to the target message.

[0109] In a possible implementation, when the vehicle-mounted terminal encrypts the target message and the vehicle query information corresponding to the target message in a preset encryption method, the server obtains the first encrypted information through the wireless network. The server decrypts the first encrypted information in a preset decryption method to obtain the target message and the vehicle query information corresponding to the target message.

[0110] The preset decryption method is a decryption method corresponding to the preset decryption method. The preset decryption method is set by a technician according to actual conditions, and the present application embodiment does not limit this.

[0111] When the preset encryption method is to use the private key of the vehicle-mounted terminal and the public key of the server to encrypt the target message and the vehicle query information corresponding to the target message, the server uses the private key of the server and the public key of the vehicle-mounted terminal to decrypt the first encrypted information to obtain the target message and the vehicle query information corresponding to the target message.

[0112] 404. The server determines whether the message type of the target message matches the vehicle query information.

[0113] In a possible implementation, when the message type of the target message is a normal message or an important message, if the vehicle query information is a vehicle identification, the server determines that the message type of the target message matches the vehicle query information; if the vehicle query information is a vehicle location, the server determines that the message type of the target message does not match the vehicle query information.

[0114] In a possible implementation, when the message type of the target message is an emergency message, if the vehicle query information is a vehicle identification, the server determines that the message type of the target message does not match the vehicle query information; if the vehicle query information is a vehicle location, the server determines that the message type of the target message matches the vehicle query information.

[0115] Optionally, after step 404, the server performs the following step 405 or 409 according to the actual situation, which is not limited in the embodiment of the present application. In addition, step 404 is an optional step, which can be executed or not executed, which is not limited in the embodiment of the present application.

[0116] 405. When the message type of the target message matches the vehicle query information, the server performs a vehicle query based on the vehicle query information to obtain at least one second vehicle.

[0117] In a possible implementation, when the vehicle query information includes at least one vehicle identification recognized by the first vehicle, the server performs a query based on the at least one vehicle identification to obtain the at least one second vehicle.

[0118] Among them, since the at least one vehicle identification is a vehicle identification recognized by the on-board terminal of the first vehicle, the at least one second vehicle is located around the first vehicle.

[0119] In this implementation, the second vehicle can be quickly found using the vehicle identification, and the query efficiency of the second vehicle is high.

[0120] For example, when the vehicle query information includes at least one vehicle identification identified by the first vehicle, the server determines at least one candidate vehicle corresponding to the at least one vehicle identification, and determines the at least one second vehicle with the message receiving function enabled from the at least one candidate vehicle.

[0121] Among them, the message receiving function is turned on and off by the car owner. When the message receiving function is turned on, the vehicle can receive messages sent by other vehicles; when the message receiving function is turned off, the vehicle cannot receive messages sent by other vehicles.

[0122] In a possible implementation manner, when the vehicle query information includes the vehicle position of the first vehicle, the server performs a query based on the vehicle position to obtain the at least one second vehicle.

[0123] The at least one second vehicle is located around the first vehicle.

[0124] In this implementation manner, the vehicle position is used to query the second vehicles around the first vehicle, and the query range is larger.

[0125] The above implementation is described below through several examples.

[0126] Example 1: When the target message indicates that the power system of the first vehicle fails, the server determines a vehicle query range corresponding to the position of the vehicle, and the vehicle query range is a range with the position of the vehicle as the center and a preset length as the radius. The server determines multiple reference vehicles within the query range. The server determines from the multiple reference vehicles the at least one second vehicle located behind the first vehicle and traveling in the same direction as the first vehicle, and / or located in front of the first vehicle and traveling in the opposite direction to the first vehicle.

[0127] For example, when the target message indicates that the power system of the first vehicle has failed, the server determines the vehicle query range corresponding to the vehicle position. Based on the vehicle positions of multiple candidate vehicles and the vehicle query range, the server determines multiple reference vehicles within the query range from the multiple candidate vehicles. The server determines the relative positions between the multiple reference vehicles and the first vehicle, the driving directions of the multiple reference vehicles, and the driving direction of the first vehicle before the failure. The server determines from the multiple reference vehicles at least one second vehicle located behind the first vehicle and with the same driving direction as the first vehicle, and / or located in front of the first vehicle and with the opposite driving direction as the first vehicle.

[0128] Example 2: When the target message indicates that the braking system or steering of the first vehicle fails, the server determines a vehicle query range corresponding to the position of the vehicle, where the vehicle query range is a range with the position of the vehicle as the center and a preset length as the radius. The server determines multiple reference vehicles within the query range. The server determines from the multiple reference vehicles the at least one second vehicle that is located in front of the first vehicle and has the same driving direction as the first vehicle, and / or that is located in front of the first vehicle and has an opposite driving direction to the first vehicle.

[0129] For example, when the target message indicates that the braking system or steering of the first vehicle fails, the server determines the vehicle query range corresponding to the vehicle position. Based on the vehicle positions of multiple candidate vehicles and the vehicle query range, the server determines multiple reference vehicles within the query range from the multiple candidate vehicles. The server determines the relative positions between the multiple reference vehicles and the first vehicle, the driving directions of the multiple reference vehicles, and the driving direction of the first vehicle before the failure. The server determines from the multiple reference vehicles the at least one second vehicle that is located in front of the first vehicle and has the same driving direction as the first vehicle, and / or, is located in front of the first vehicle and has an opposite driving direction to the first vehicle.

[0130] 406. The server forwards the target message to the at least one second vehicle.

[0131] In some embodiments, in addition to the target message, the server can also send the vehicle identification of the first vehicle to the at least one second vehicle so that the second vehicle knows the sender of the target message.

[0132] In a possible implementation manner, the server sends the target message to the at least one second vehicle via a wireless network.

[0133] For example, the server encrypts the target message using a preset encryption method to obtain second encrypted information, and the server sends the second encrypted information to the at least one second vehicle via a wireless network.

[0134] 407. The second vehicle receives the target message.

[0135] The second vehicle refers to any second vehicle among the at least one second vehicle.

[0136] In a possible implementation, the on-board terminal of the second vehicle obtains the target message through a wireless network.

[0137] For example, when the server encrypts the target message using a preset encryption method, the vehicle-mounted terminal of the second vehicle obtains the second encrypted information, and decrypts the second encrypted information using a preset decryption method to obtain the target message.

[0138] 408. The second vehicle displays the target message.

[0139] In a possible implementation, the vehicle-mounted terminal of the second vehicle determines a message display mode of the target message based on the message type of the target message, and the vehicle-mounted terminal of the second vehicle displays the target message using the message display mode.

[0140] The correspondence between the message type and the message display mode is set by the technician according to the actual situation, and the embodiment of the present application does not limit this. The message display mode includes the message display position and the message display form.

[0141] In this implementation, the message display mode is determined based on the message type, and the determined message display mode is used to display the target message, so that the display mode is more suitable when displaying the target message.

[0142] For example, when the message type of the target message is a normal message, the on-board terminal of the second vehicle determines the message display mode of the target message to be displayed in text form on the dashboard / HUD (Head Up Display). When the message type of the target message is an important message, the on-board terminal of the second vehicle determines the message display mode of the target message to be displayed in text form on the dashboard / HUD and the central control screen, and a highlight flashing effect is applied when the message is displayed in text form. When the message type of the target message is an emergency message, the on-board terminal of the second vehicle determines the message display mode of the target message to be displayed in text form on the dashboard / HUD and the central control screen, and a highlight flashing effect is applied when the message is displayed in text form, and a voice broadcast is added. The on-board terminal of the second vehicle uses this message display mode to display the target message.

[0143] In a possible implementation, when the second vehicle receives the target message and the vehicle identification of the first vehicle, the vehicle-mounted terminal of the second vehicle determines whether the first vehicle is a blacklisted vehicle based on the vehicle identification of the first vehicle. If the first vehicle is not a blacklisted vehicle, the vehicle-mounted terminal of the second vehicle displays the target message. If the first vehicle is a blacklisted vehicle, the vehicle-mounted terminal of the second vehicle does not display the target message.

[0144] The blacklist is used to store the vehicle identifications of the blacklisted vehicles, and the blacklist is managed by the owner of the second vehicle, that is, adding or deleting vehicles from the blacklist.

[0145] In this implementation, before displaying the target message, it is first determined whether the sender of the target message is a blacklisted vehicle, to ensure that the second vehicle will not be harassed by the blacklisted vehicle.

[0146] 409. When the message type of the target message does not match the vehicle query information, the server sends an error reminder to the first vehicle, where the error reminder is used to prompt that the message type of the target message does not match the vehicle query information.

[0147] Through step 409, when the message type of the target message does not match the vehicle query information, the server can promptly remind the first vehicle to make adjustments to ensure normal transmission of the target message.

[0148] In order to more clearly illustrate the technical solution provided by the embodiment of the present application, Figure 5 and Figure 6 The message sending method provided in the embodiment of the present application is described.

[0149] See also Figure 5 , when the message type of the target message is a common message or an important message, the vehicle terminal of the first vehicle obtains the vehicle image around the first vehicle through the camera. The vehicle terminal of the first vehicle determines at least one license plate number based on the vehicle image. The vehicle terminal of the first vehicle uploads the target message, the license plate number of the first vehicle and the at least one license plate number to the server. The server determines at least one second vehicle based on the at least one license plate number, and sends the target message and the license plate number of the first vehicle to the at least one second vehicle, so that the at least one second vehicle displays the target message, thereby realizing the message transmission between the first vehicle and the at least one second vehicle.

[0150] See also Figure 6 In the case where the message type of the target message is an emergency message, the vehicle terminal of the first vehicle obtains the vehicle position of the first vehicle through the vehicle positioning device. The vehicle terminal of the first vehicle uploads the target message, the license plate number of the first vehicle and the vehicle position to the server. The server determines at least one second vehicle based on the vehicle position, and sends the target message and the license plate number of the first vehicle to the at least one second vehicle, so that the at least one second vehicle displays the target message, thereby realizing message transmission between the first vehicle and the at least one second vehicle.

[0151] All the above optional technical solutions can be arbitrarily combined to form optional embodiments of the present application, which will not be described one by one here.
