[0043] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0044] refer to Figure 1 , Figure 1 This is a schematic diagram of a multi-vehicle linkage safety control method according to an embodiment of the present application. Figure 1 As shown, the method is applied to a cloud platform, and the method includes:

[0045] Step S1: receiving accident scene data and driving data collected by a first vehicle, where the first vehicle is a vehicle that directly monitors the accident scene and obtains the accident scene data.

[0046] In this embodiment, the functions of the cloud platform to which the method of the present application is applied include: the ability to transmit, analyze, process and store massive amounts of data in real time; equipped with an AI large model, capable of analyzing and processing various types of data inputs, and generating control information for each intelligent networked vehicle; having a universal interface, capable of communicating with each intelligent networked vehicle; having a secure interface, capable of controlling each intelligent networked vehicle in a secure manner; following the user privacy agreement, the user of the vehicle terminal authorizes the corresponding data acquisition and control authority. The functions of the vehicle controlled in the method of the present application include: the collection and uploading functions of speed, acceleration, vehicle distance, self-positioning information, etc.; at least including basic active / passive safety systems, such as AEB (Autonomous Emergency Braking, automatic emergency braking system), RAEB (Rear Automatic Emergency Braking, rear automatic emergency braking); basic intelligent networked vehicle control capabilities (such as direction control, speed control, etc.); having a universal interface, capable of uploading / downloading various types of driving, road, and traffic data; having a secure interface, enabling the caller (that is, the cloud platform) to perform basic vehicle control.

[0047] In this embodiment, the first vehicle refers to a vehicle that directly monitors the accident scene and obtains the accident scene data. At the same time, the first vehicle is also a vehicle that has authorized the cloud platform to obtain its own driving data, obtain its own environmental data collected for environmental perception, and perform basic vehicle control on itself. For vehicles that have authorized the cloud platform to obtain its own driving data, obtain its own environmental data collected for environmental perception, and perform basic vehicle control on itself, the vehicle will perform real-time environmental perception during actual driving, and analyze and process the environmental data collected during the environmental perception process to determine whether a safety accident has occurred in the current front corresponding to the environmental data. In the case of determining that a safety accident has occurred, the vehicle will be determined as the first vehicle, and the environmental data currently collected by the first vehicle will be determined as accident scene data, and the accident scene data and the vehicle's driving data will be uploaded to the cloud platform. Among them, the vehicle end of the first vehicle has a certain data processing capability. When it is determined that a safety accident has occurred, the relative position relationship between the location of the accident and its current position will be determined through analysis and processing (such as the location of the accident is 100m away, 20° to the right of the current position of the vehicle). The accident scene data will record this relative position relationship and will also include relevant driving data of other vehicles currently in front of the vehicle. The cloud platform determines the specific location of the accident based on the relative position relationship and the vehicle's own positioning information recorded in the driving data of the first vehicle.

[0048] Step S2: According to the accident location information in the received accident scene data, a second vehicle within the set range is determined, where the second vehicle is a vehicle that has not monitored the accident scene and has the authority to obtain its location information.

[0049] In this embodiment, when the cloud platform receives the accident scene data and driving data sent by the first vehicle, it is determined that an accident has occurred in front of the first vehicle. At this time, the cloud platform determines the location of the accident based on the accident location information in the accident scene data uploaded by the first vehicle. And based on the accident location information, determine the second vehicle within the set range of the location. Among them, the set range can be set according to the actual application scenario, and is not specifically limited here, such as 500m or 300m. Among them, the second vehicle is a vehicle that has not monitored the accident scene, and the second vehicle is at least a vehicle that has authorized the cloud platform to obtain its own location information.

[0050] Step S3: Acquire the driving data and environmental data of the second vehicle according to the authority authorized by the second vehicle.

[0051] In this embodiment, in order to protect user privacy, the cloud platform will request the user on the vehicle side for the permission to obtain the relevant data information of the vehicle, and the application allows each vehicle to authorize different permission ranges according to the needs of its own users. For example, some vehicle users only give the cloud platform the permission to obtain positioning information, while some vehicle users give the cloud platform the permission to obtain positioning information, driving data and scene data, etc. After determining the second vehicle within the set range, determine which second vehicles within the set range give the cloud platform the permission to obtain their own driving data and environmental data, and then the cloud platform starts to obtain driving data and environmental data obtained by environmental perception from these second vehicles.

[0052] Step S4: By analyzing the accident scene data and driving data of the first vehicle and the environmental data and driving data of the second vehicle, the control information of each vehicle is determined and sent to the corresponding vehicle.

[0053] In this embodiment, after the cloud platform obtains the accident scene data and driving data of the first vehicle in the same accident scene, as well as the environmental data and driving data of the second vehicle within a set range of the same accident scene, the AI ​​big model configured by the cloud platform analyzes and processes these data, and based on the analysis and processing results, obtains control information for each of the first vehicles and the second vehicles in the same accident scene, and then sends each control information to its corresponding vehicle to control each vehicle to perform corresponding control actions.

[0054] A multi-vehicle linkage safety control method provided in an embodiment of the present application is applied to a cloud platform, first receiving accident scene data and driving data collected by a first vehicle, where the first vehicle is a vehicle that directly monitors the accident scene and obtains the accident scene data; determining a second vehicle within a set range based on the accident location information in the received accident scene data, where the second vehicle is a vehicle that has not monitored the accident scene and has the authority to obtain its location information; obtaining the driving data and environmental data of the second vehicle based on the authority authorized by the second vehicle; determining and sending the control information of each vehicle to the corresponding vehicle by analyzing the accident scene data and driving data of the first vehicle and the environmental data and driving data of the second vehicle. Therefore, a multi-vehicle linkage safety control method provided by the present application can perform cluster safety control on all vehicles within a certain range of the accident even if only some of the vehicles in front monitor and determine that an accident has occurred ahead. Even vehicles that cannot monitor the safety accident can be safety controlled, thereby effectively avoiding the occurrence of continuous safety accidents (for example, a traffic accident occurs in front of the first vehicle, and the second vehicle is unable to monitor the traffic accident in front and continues to drive normally, which may cause the first vehicle to brake or turn the steering wheel in an emergency, while the second vehicle fails to make corresponding control actions in time, resulting in a traffic accident between the second vehicle and the vehicle in front).

[0055] In combination with the above embodiments, in one implementation, the embodiment of the present application also provides a multi-vehicle linkage safety control method. In the multi-vehicle linkage safety control method, when there are multiple first vehicles, before step S4, the method further includes: determining the first vehicle at the same accident scene according to the accident location information in the accident scene data of the multiple first vehicles received; fusing and correcting the accident scene data of the first target vehicle with the accident scene data collected from all first vehicles except the first target vehicle at the same accident scene, to obtain more accurate accident scene data of the first target vehicle, the first target vehicle being any first vehicle at the same accident scene.

[0056] In this embodiment, there may be multiple first vehicles that directly monitor the same accident scene and obtain accident scene data. In order to ensure that the cloud platform can perform analysis and processing based on more accurate accident scene data, thereby obtaining more effective control information for avoiding continuous accidents, the present application will fuse and correct the multiple accident scene data corresponding to the multiple first vehicles that directly monitor the same accident scene, and obtain accident scene data that can more accurately reflect the situation at the accident scene.

[0057] Specifically, based on the accident location information in the accident scene data of each first vehicle received by the cloud platform, it is determined whether each accident location information is within a certain range. The certain range can be set according to the actual application scenario, and is not specifically limited here, such as 2m, 5m, etc. If the accident location information in the accident scene data of multiple first vehicles is within the certain range, it is determined that the accident scene data of the multiple first vehicles come from the first vehicle set at the same accident scene. At this time, for the first vehicle set, the cloud platform selects a first vehicle each time, and then uses the accident scene data of all first vehicles in the first vehicle set except the selected first vehicle to fuse and correct the accident scene data of the selected first vehicle, so as to obtain more accurate accident scene data corresponding to the selected first vehicle, and based on the same implementation method, the accident scene data of each first vehicle in the first vehicle set is fused and corrected once. When the subsequent cloud platform analyzes and processes the accident scene data of the first vehicle, it uses the fused and corrected accident scene data.

[0058] In combination with the above embodiments, in one implementation, the embodiment of the present application further provides a multi-vehicle linkage safety control method. In the multi-vehicle linkage safety control method, the method further includes: requesting data acquisition permission from the vehicle terminal based on the user privacy protocol; and determining the scope of the permission authorized by the vehicle terminal according to the feedback information received from the vehicle terminal.

[0059] In this embodiment, in order to protect user privacy, the cloud platform will request the user on the vehicle side for the permission to obtain relevant data information of the vehicle, and the application allows each vehicle to authorize different permission ranges according to the needs of its own users. The cloud platform requests data acquisition permission from the vehicle side of each vehicle based on the user privacy agreement. After the vehicle side receives the request, the user on the vehicle will authorize it, and the authorized permission level includes at least the first level that only authorizes the acquisition of the vehicle's positioning information; the second level that authorizes the acquisition of the vehicle's positioning information, driving data and scene data. Feedback information is sent to the cloud platform based on the user's authorization operation, and the feedback information records at least the corresponding authorized permission level and the corresponding vehicle identification information. The cloud platform determines and records the permission level authorized by each vehicle based on the feedback information received from each vehicle.

[0060] In combination with the above embodiments, in one implementation, the present application embodiment further provides a multi-vehicle linkage safety control method. In the multi-vehicle linkage safety control method, step S4 may include steps S41 to S44:

[0061] Step S41: Determine whether there is a safety risk in driving the first vehicle by analyzing the accident scene data and driving data of the first vehicle.

[0062] In this embodiment, the cloud platform performs comprehensive analysis and processing on the accident scene data and driving data of each first vehicle at the same accident scene to determine whether there is a first vehicle with driving safety risks among the first vehicles.

[0063] Step S42: In the event of a safety risk, determining the future movement trajectory of the first vehicle according to the control information of the first vehicle.

[0064] In this embodiment, when there is a first vehicle with a driving safety risk at the same accident scene, the first vehicle with a driving safety risk is further analyzed and processed to determine control information for the first vehicle that can effectively avoid a safety accident. After the first vehicle receives the control information sent by the cloud platform and executes the corresponding control action, the first vehicle will avoid a safety accident. At the same time, after determining that the control information is obtained, the cloud platform further analyzes and processes to predict the movement trajectory of the first vehicle after the first vehicle executes the control action corresponding to the control information, and the movement trajectory at least includes the specific positions at different times.

[0065] Step S43: determining control information of the second vehicle by analyzing the future motion trajectory of the first vehicle, the environmental data and the driving data of the second vehicle.

[0066] In this embodiment, after predicting and determining the future motion trajectory of the first vehicle, the cloud platform analyzes and processes the motion trajectory and the environmental data and driving data of the second vehicle within the set range that has not monitored the same accident scene, and determines the corresponding control information for the second vehicle. After the second vehicle receives the control information for the second vehicle issued by the cloud platform and executes the corresponding control action, the second vehicle can avoid a safety accident and avoid a collision with the first vehicle that executes the corresponding control action.

[0067] Step S44: When there is no safety risk, the first vehicle and the second vehicle are warned.

[0068] In this embodiment, when there is a first vehicle with a driving safety risk at the same accident scene, only the first vehicle and the second vehicle at the same accident scene are warned to remind the vehicles to drive safely when an accident occurs ahead.

[0069] In combination with the above embodiments, in one implementation, the embodiment of the present application further provides a multi-vehicle linkage safety control method. In the multi-vehicle linkage safety control method, the accident scene data and driving data collected by the first vehicle received are sent by the first vehicle when analyzing the environmental data collected by itself and determining that an accident has occurred in the current environment, or the accident scene data and driving data collected by the first vehicle received are actively sent by the user.

[0070] In this embodiment, for vehicles that have authorized the cloud platform to obtain their own driving data, obtain their own environmental data collected for environmental perception, and perform basic vehicle control on themselves, the vehicle will perform real-time environmental perception during actual driving, and analyze and process the environmental data collected during the environmental perception process to determine whether a safety accident has occurred in the current front corresponding to the environmental data. In the case of determining that a safety accident has occurred, the vehicle will be determined as the first vehicle, and the environmental data currently collected by the first vehicle will be determined as accident scene data, and the accident scene data and the driving data of the vehicle will be uploaded to the cloud platform. At the same time, in order to avoid the vehicle end being affected by the environment during the analysis of the environmental data collected by itself, and the first vehicle identifying the safety accident in front as the absence of a safety accident does not actively upload the environmental data and driving data currently collected by itself, the application can also be initiated by the user to send the currently collected accident scene data and driving data to the cloud platform.

[0071] In combination with the above embodiments, in one implementation, the embodiment of the present application further provides a multi-vehicle linkage safety control method. In the multi-vehicle linkage safety control method, when the driving data includes the control limit range of various motion parameters in various speed intervals, the method further includes: obtaining relevant driving data of the vehicle at preset time intervals; determining and updating the control limit range of various operating parameters of the vehicle in various speed intervals by analyzing the obtained relevant driving data, and the operating parameters include at least acceleration and deceleration time and turning radius.

[0072] In this embodiment, when the cloud platform obtains control information through analysis and processing, due to the different vehicle models and the degree of wear during the use of the vehicle during the control process, the control limit ranges of different vehicles will be different. For example, a new car will take less time to decelerate in a speed range, while some old cars may take more time to decelerate in the same speed range. When the cloud platform obtains control information through analysis and processing, it is necessary to consider the control limit ranges of different vehicles, so as to better control the vehicles and avoid safety accidents. In actual use, the same vehicle will cause further wear during use, so that its control limit range will change accordingly. Therefore, in order to analyze and obtain better control information, this application will recalibrate the control limit range of each vehicle at regular intervals.

[0073] Specifically, relevant driving data of the vehicle for a period of time is acquired at preset intervals, wherein the preset duration can be set according to actual application scenarios, such as half a year or a year, and the period of time can be set according to actual application scenarios, such as a week or half a month, etc. By analyzing the acquired relevant driving data of the vehicle, the control limit ranges of various operating parameters of the vehicle in each speed range are determined and updated, wherein the operating parameters at least include the acceleration and deceleration time of the vehicle in each speed range and the turning radius in each speed range.

[0074] In combination with the above embodiments, in one implementation, the embodiment of the present application further provides a multi-vehicle linkage safety control method. In the multi-vehicle linkage safety control method, in the case that the second vehicle is authorized to obtain only the positioning information, the obtaining of the driving data and environmental data of the second vehicle according to the authorization of the second vehicle includes: according to the authorization of the second vehicle to obtain only the positioning information, prohibiting the obtaining of the driving data and environmental data of the second vehicle; the determining and sending the control information of each vehicle to the corresponding vehicle by analyzing the accident scene data and driving data of the first vehicle and the environmental data and driving data of the second vehicle includes: in the case that the second vehicle is authorized to obtain only the positioning information, by analyzing the accident scene data and driving data of the first vehicle and the positioning information of the second vehicle, determining and sending the control information of the first vehicle to the first vehicle, and sending the corresponding warning information to the second vehicle; in the case that the second vehicle is authorized to obtain only the positioning information, the environmental data and driving data, by analyzing the accident scene data and driving data of the first vehicle and the environmental data and driving data of the second vehicle, determining and sending the control information of each vehicle to the corresponding vehicle.

[0075] In this embodiment, for the second vehicle at the same accident scene that has only given the cloud platform permission to obtain its own location information, the cloud platform will not obtain the driving data and environmental data of the second vehicle. At this time, the cloud platform will only warn the second vehicle, and will not generate corresponding control information through analysis. However, for the second vehicle at the same accident scene that has given the cloud platform permission to obtain its own location information, driving data and scene data, the cloud platform will obtain the driving data and environmental data of the second vehicle. At this time, the cloud platform will analyze the accident scene data and driving data of the first vehicle and the environmental data and driving data of the second vehicle, determine and send the control information for the first vehicle to the first vehicle and the control information for the second vehicle to the second vehicle, so as to control each vehicle to perform its corresponding control action.

[0076] Based on the same inventive concept, an embodiment of the present application provides a multi-vehicle linkage safety control system, such as Figure 2 As shown, the system 200 is applied to a cloud platform and includes:

[0077] The message receiving and sending middleware 201 is used to receive the accident scene data and driving data collected by the first vehicle, where the first vehicle is a vehicle that directly monitors the accident scene and obtains the accident scene data;

[0078] The vehicle position information processing unit 202 is used to determine a second vehicle within a set range according to the accident location information in the received accident scene data, where the second vehicle is a vehicle that has not been monitored at the accident scene and has the permission to obtain its location information;

[0079] The vehicle position information processing unit 202 is used to obtain the driving data and environmental data of the second vehicle based on the message receiving and sending middleware according to the authority authorized by the second vehicle;

[0080] A data analysis and processing unit 203, configured to determine control information of each vehicle by analyzing the accident scene data and driving data of the first vehicle and the environment data and driving data of the second vehicle;

[0081] The information feedback and vehicle control unit 204 is used to send the control information of each vehicle to the corresponding vehicle through the message receiving and sending middleware.

[0082] In this embodiment, if Figure 3 As shown, after receiving the data information uploaded by each vehicle, the message transceiver middleware in a multi-vehicle linkage safety control system provided by the present application first classifies the data, and different types of data are processed by the corresponding processing units to improve the processing efficiency. Specifically, three data processing units are provided, namely, a vehicle position information processing unit, a vehicle speed acceleration information processing unit, and a vehicle warning information processing unit, and the processed data is given to a multi-vehicle vehicle status identification unit. The multi-vehicle vehicle status identification unit summarizes the single vehicle information and extracts key information for subsequent model analysis and processing, and divides multiple vehicles within the set range of the same accident scene into a traffic group, and processes them separately according to the message type (driving data, accident scene data, environmental data, warning information). Driving data, accident scene data and environmental data: transmitted to the AI ​​processing large model, and the model then analyzes and makes decisions and regulations; the AI ​​large model feeds back the decision results to the information feedback and vehicle control unit, and this unit then transmits the control and / or warning information to each vehicle in this traffic group through the message transceiver middleware to achieve the purpose of multi-vehicle control. Warning information: For the second vehicle that only provides positioning authority, the model analysis and processing is not performed, and it is directly transmitted to the information feedback and vehicle control unit, and broadcasted to this type of second vehicle in a traffic group through the message sending and receiving middleware. At the same time, in order to warn all vehicles connected to the cloud platform, it will also broadcast to other vehicles authorized with the maximum authority. The difference is that control analysis will not be performed here for the second vehicle that only provides positioning authority. The AI ​​processing large model is configured in the data analysis and processing unit to determine the control and / or warning information for each vehicle.

[0083] Optionally, the system 200 further includes:

[0084] A vehicle position information processing unit, for determining, when the first vehicle includes a plurality of first vehicles, a first vehicle at a same accident scene according to the accident location information in the received accident scene data of the plurality of first vehicles;

[0085] A data correction unit is used to fuse and correct the accident scene data of the first target vehicle with the accident scene data collected from all first vehicles except the first target vehicle at the same accident scene, so as to obtain more accurate accident scene data of the first target vehicle. The first target vehicle is any first vehicle at the same accident scene.

[0086] Optionally, the system 200 further includes:

[0087] A permission request unit, used to request data acquisition permission from the vehicle terminal based on the user privacy agreement;

[0088] The authority determination unit is used to determine the authority scope authorized by the vehicle terminal according to the feedback information received from the vehicle terminal.

[0089] Optionally, a data analysis and processing unit includes:

[0090] A first analysis and processing unit, configured to determine whether there is a safety risk in driving the first vehicle by analyzing the accident scene data and driving data of the first vehicle;

[0092] a second analysis and processing unit, configured to determine control information of the second vehicle by analyzing the future motion trajectory of the first vehicle, environmental data and driving data of the second vehicle;

[0093] The early warning unit is used to warn the first vehicle and the second vehicle when there is no safety risk.

[0094] Optionally, the accident scene data and driving data collected by the first vehicle are issued by the first vehicle when it analyzes the environmental data collected by itself and determines that an accident has occurred in the current environment, or the accident scene data and driving data collected by the first vehicle are actively issued by the user.

[0095] Optionally, the system 200 further includes:
