Description

Technical Field

[0001] This invention relates to the field of vehicle data processing technology, and in particular to a vehicle data processing system and method. Background Technology

[0002] As the number of vehicles continues to increase, so do vehicle accidents. The causes of these accidents vary, so it is necessary to identify the party responsible for the accident.

[0003] In related technologies, vehicles typically use their own cameras to record information about objects ahead at the moment of an accident. This information is then uploaded to the cloud, and the cause of the accident is determined by analyzing the information about vehicles, pedestrians, and obstacles ahead at the moment of the accident. However, the lack of protection for the target information during data upload makes it susceptible to problems such as data leakage, theft, and modification, resulting in serious impacts or security vulnerabilities in the data upload process. Summary of the Invention

[0013] Furthermore, the vehicle-related data includes: the motion data of the target vehicle and the obstacle data surrounding the target vehicle.

[0014] Furthermore, the system also includes: the EDR control module, configured to, in response to the target feedback data including collision-related data associated with the EDR event, determine a first total amount of the collision-related data, and send the first total amount of data to the host computer through the diagnostic module; the host computer is further configured to, upon receiving the first total amount of data, generate a data upload instruction, and send the data upload instruction to the EDR control module through the diagnostic module; the EDR control module is further configured to, in response to the data upload instruction, acquire the collision-related data associated with the EDR event, and call a preset data upload interface to upload the collision-related data to the host computer; the host computer is further configured to, receive the collision-related data uploaded by the EDR control module, determine a second total amount of the collision-related data, and, if the second total amount of data is consistent with the first total amount of data, display the collision-related data.

[0015] Furthermore, the system also includes: the EDR control module includes a data acquisition unit, a data processing unit, and a data storage unit; wherein, the data acquisition unit is used to acquire vehicle operation data of the target vehicle according to preset rules; the data processing unit is used to determine collision-related data associated with the EDR event from the vehicle operation data, and store the collision-related data in the data storage unit.

[0016] Furthermore, the data processing unit further includes: after determining the collision-related data associated with the EDR event from the vehicle operation data, clearing the data storage unit, and storing the collision-related data in the data storage unit.

[0017] Furthermore, the data processing unit further includes: preprocessing the collision-related data according to the data type of the collision-related data, and storing the preprocessed collision-related data in the data storage unit.

[0018] Furthermore, the system also includes: the EDR control module, used to determine the preset prompt information as the target feedback data when performing the data recording operation of the EDR event.

[0019] According to another aspect of the present invention, a vehicle data processing method is provided, applied to a vehicle data processing system, the vehicle data processing system including a host computer, a diagnostic module, and an EDR control module, the EDR control module including a shooting unit, a processing module, and an image transmission unit, the method comprising:

[0020] The host computer receives a data acquisition request from the target user and sends the data acquisition request to the diagnostic module. The data acquisition request carries the user attribute information of the target user.

[0021] In response to the received data acquisition request, the diagnostic module generates a random key, generates first verification data based on the random key and the user attribute information carried in the data acquisition request, and sends the random key to the host computer.

[0022] The host computer receives the random key sent by the diagnostic module, generates second verification data based on the random key and the user attribute information, and sends the second verification data to the diagnostic module.

[0023] If the first verification data and the second verification data are consistent, the diagnostic module sends the data acquisition request to the EDR control module.

[0024] The EDR control module generates target feedback data corresponding to the data acquisition request, and feeds the target feedback data back to the host computer through the diagnostic module, and displays the target feedback data through the host computer.

[0025] The technical solution of this invention involves a host computer receiving a data acquisition request from a target user for an EDR event and sending the request to a diagnostic module. The data acquisition request carries the target user's user attribute information, enabling authentication based on the request and improving the protection of the target's feedback data. The diagnostic module, in response to the received data acquisition request, generates a random key and, based on the random key and the user attribute information carried in the data acquisition request, generates first verification data and sends the random key to the host computer, thereby verifying the legitimacy of the data acquisition request and ensuring its security. The host computer can also receive the random key sent by the diagnostic module and, based on the random key and user attribute information, generate second verification data and send the second verification data to the host computer. Data is sent to the diagnostic module. Similarly, the host computer and the diagnostic module calculate and verify the data respectively, thereby verifying the legitimacy of the user's identity in the data acquisition request. This ensures the security of the data acquisition request and improves the security and integrity of data storage. The diagnostic module can also send the data acquisition request to the EDR control module if the first and second verification data match, allowing the acquisition of target data based on a legitimate request and ensuring data acquisition security. The EDR control module generates target feedback data corresponding to the data acquisition request and feeds it back to the host computer through the diagnostic module. The host computer then displays the target feedback data, effectively ensuring the security and accuracy of the data upload process. Therefore, this technical solution, through the above methods, can accurately, securely, and efficiently transmit target feedback data to the host computer, enabling accurate analysis of events based on the transmitted data and making the analysis results more realistic and reliable.

[0042] Example 1

[0043] Figure 1This invention provides a schematic diagram of a vehicle data processing system according to Embodiment 1. This embodiment is applicable to scenarios involving secure transmission of automotive EDR data. The system includes: a host computer 101, a diagnostic module 102, and an EDR control module 103. The host computer 101 can receive a data acquisition request from a target user for an EDR event and send the data acquisition request to the diagnostic module. The data acquisition request carries the user attribute information of the target user. The diagnostic module 102 can generate a random key in response to the received data acquisition request, generate first verification data based on the random key and the user attribute information carried in the data acquisition request, and send the random key to the host computer. The host computer 101 can also receive the random key sent by the diagnostic module, generate second verification data based on the random key and the user attribute information, and send the second verification data to the diagnostic module. If the first verification data and the second verification data are consistent, the diagnostic module 102 can also send the data acquisition request to the EDR control module. The EDR control module 103 can generate target feedback data corresponding to the data acquisition request, feed the target feedback data back to the host computer through the diagnostic module, and display the target feedback data through the host computer.

[0044] like Figure 1 As shown, the host computer 101 is used to receive a data acquisition request from the target user for an EDR event and send the data acquisition request to the diagnostic module, wherein the data acquisition request carries the user attribute information of the target user; the diagnostic module 102 is used to respond to the received data acquisition request, generate a random key, generate first verification data based on the random key and the user attribute information carried in the data acquisition request, and send the random key to the host computer; the host computer 101 is also used to receive the random key sent by the diagnostic module, generate second verification data based on the random key and the user attribute information, and send the second verification data to the diagnostic module; the diagnostic module 102 is used to send the data acquisition request to the EDR control module if the first verification data and the second verification data are consistent; the EDR control module 103 is also used to generate target feedback data corresponding to the data acquisition request, feed the target feedback data back to the host computer through the diagnostic module, and display the target feedback data through the host computer.

[0045] EDR events typically refer to events such as emergency braking or collisions that occur in a vehicle. Generally, when an EDR event occurs, the vehicle's intelligent driving control device can record and lock data for the period before and after the event to store important data. User attribute information typically includes at least one of the following: username, user ID, verification password, and biometric information. First verification data refers to the verification data calculated by the diagnostic module. Second verification data refers to the verification data calculated by the host computer. Target feedback data may specifically include collision-related data or preset prompt information. Collision-related data is obtained by the EDR control module after recording the EDR event data; it can serve as positive feedback to instruct subsequent data transmission operations. Preset prompt information indicates that the EDR control module is performing EDR event data recording operations but cannot transmit data; it can serve as negative feedback to indicate that the EDR control module cannot transmit data.

[0046] Specifically, this technical solution verifies the data acquisition request sent by the host computer by comparing the first verification data generated by the diagnostic model with the second verification data generated by the host computer. If the verification matches, the data acquisition request is sent to the EDR control module. The target feedback data corresponding to the acquisition request is then obtained from the EDR control module and uploaded to the host computer. This achieves secure and accurate transmission of the target feedback data, preventing data theft and tampering, and effectively protecting data privacy.

[0047] EDR control module 103 is used to acquire collision-related data associated with the EDR event without performing data recording operation for the EDR event, and to determine the collision-related data as target feedback data.

[0048] The collision-related data can include vehicle-related data within a first time period before the target time of the collision, and vehicle-related data within a second time period after the target time. Specifically, the vehicle-related data can include the target vehicle's motion data and surrounding obstacle data. Motion data can include information such as vehicle speed, braking distance, direction of movement, and distance. Surrounding obstacle data can include information such as the positions of other vehicles, pedestrians, the distance between pedestrians and the target vehicle, and the distance between other vehicles and the target vehicle. The target vehicle can be understood as the vehicle for which EDR event data transmission is required.

[0049] Specifically, based on the data acquisition request sent by the diagnostic module to the EDR control module, the response status of the EDR control module is determined. If a positive response is received from the EDR control module, it is considered that the EDR control module has not performed the data recording operation of the EDR event. At this time, the EDR control module 103 can acquire the collision association data associated with the EDR event, identify the collision association data as the target feedback data, and feed the target feedback data back to the host computer. Thus, when the EDR control module 103 is idle, it can complete the secure transmission of the target feedback data and protect the privacy of the data.

[0050] The EDR control module 103 is further configured to respond to target feedback data, including collision-related data associated with the EDR event, determine a first total amount of collision-related data, and send the first total amount of data to the host computer through the diagnostic module; the host computer 101 is further configured to generate a data upload command after receiving the first total amount of data, and send the data upload command to the EDR control module through the diagnostic module; the EDR control module 103 is further configured to respond to the data upload command, acquire the collision-related data associated with the EDR event, and call a preset data upload interface to upload the collision-related data to the host computer; the host computer 101 is further configured to receive the collision-related data uploaded by the EDR control module, determine a second total amount of collision-related data, and display the collision-related data if the second total amount of data is consistent with the first total amount of data.

[0051] The first total data volume refers to the number of bytes of collision-related data directly calculated from the EDR control module. The second total data volume refers to the number of bytes of target feedback data calculated at the host computer.

[0052] Specifically, firstly, the EDR control module 103, in response to a data acquisition request, generates target feedback data corresponding to the data acquisition request and calculates the first total data volume of collision-related data associated with the EDR event. This first total data volume is then sent to the host computer via the diagnostic module. Secondly, upon receiving the first total data volume, the host computer generates a data upload command and sends it to the EDR control module via the diagnostic module. This allows the EDR control module to call a preset data upload interface to upload the collision-related data associated with the EDR event to the host computer. Finally, the host computer calculates the received total collision-related data volume and a second total data volume, and displays the collision-related data by comparing the first and second total data volumes. This technical solution, through the above steps, enables rapid and accurate uploading of target feedback data in response to a data acquisition request, and ensures the accuracy and integrity of the data transmission process by comparing the data volume.

[0053] The EDR control module 103 may further include a data acquisition unit, a data processing unit, and a data storage unit; wherein, the data acquisition unit is used to acquire vehicle operation data of the target vehicle according to preset rules; the data processing unit is used to determine collision-related data associated with the EDR event from the vehicle operation data, and store the collision-related data in the data storage unit.

[0054] The target vehicle refers to a vehicle that has experienced a driving cycle-based driving event. The data collection methods used in accordance with preset rules can include at least one of the following: time-based periodic collection, feature-event-based triggering collection, condition-based intelligent collection, and driving cycle-based collection. Vehicle operation data can include at least one of the following: vehicle location data, vehicle status data, powertrain data, and fault information.

[0055] Specifically, the EDR control module may further include a data acquisition unit, a data processing unit, and a data storage unit. The data acquisition unit can collect vehicle operation data of the target vehicle according to preset rules, and the data processing unit can use the vehicle operation data to determine the collision correlation data associated with the EDR event, thereby storing the collision correlation data in the data storage unit. Through this technical step, vehicle operation data can be stored in a timely and accurate manner for analysis and processing of vehicle operation status, emergency events, and other situations.

[0056] The data processing unit is further configured to, after determining the collision-related data associated with the EDR event from the vehicle operation data, clear the data storage unit and store the collision-related data in the data storage unit.

[0057] Specifically, after the data processing unit can identify the collision-related data associated with the EDR event from the vehicle operation data, it can also clear all the data in the data storage unit, thereby storing only the identified collision-related data in the data storage unit. This can effectively reduce the pressure on the data storage unit and ensure that the data storage unit always stores the latest EDR event information, thus improving the utilization efficiency of the data storage unit.

[0058] The data processing unit is further configured to preprocess the collision-related data according to the data type of the collision-related data, and store the preprocessed collision-related data in the data storage unit.

[0059] Preprocessing mainly refers to at least one of the following operations on collision-related data: cleaning, transformation, reconstruction, and encryption.

[0060] The specific data processing unit preprocesses different types of collision-related data according to the data type of the collision-related data, and then stores the cleaned and encrypted collision-related data into the data storage unit, thereby realizing the encryption processing of the data and improving the protection of the collision-related data.

[0061] The EDR control module is used to determine the preset prompt information as the target feedback data when performing the data recording operation of the EDR event.

[0062] Specifically, based on the data acquisition request sent by the diagnostic module to the EDR control module, the response status of the EDR control module is determined. If a negative response is received from the EDR control module, it is assumed that the EDR control module is performing data recording operations for the EDR event. The preset prompt information corresponding to the negative response is then used as the target feedback data, and the target feedback data is sent to the host computer through the diagnostic module. This enables the host computer to continuously issue data upload commands, thereby completing the upload operation of the collision-related data associated with the EDR event.

[0063] The technical solution of this invention involves a host computer receiving a data acquisition request from a target user for an EDR event and sending the request to a diagnostic module. The data acquisition request carries the target user's user attribute information, enabling authentication based on the request and improving the protection of the target's feedback data. The diagnostic module, in response to the received data acquisition request, generates a random key and, based on the random key and the user attribute information carried in the data acquisition request, generates first verification data and sends the random key to the host computer, thereby verifying the legitimacy of the data acquisition request and ensuring its security. The host computer can also receive the random key sent by the diagnostic module and, based on the random key and user attribute information, generate second verification data and send the second verification data to the host computer. Data is sent to the diagnostic module. Similarly, the host computer and the diagnostic module calculate and verify the data respectively, thereby verifying the legitimacy of the user's identity in the data acquisition request. This ensures the security of the data acquisition request and improves the security and integrity of data storage. The diagnostic module can also send the data acquisition request to the EDR control module if the first and second verification data match, allowing the acquisition of target data based on a legitimate request and ensuring data acquisition security. The EDR control module generates target feedback data corresponding to the data acquisition request and feeds it back to the host computer through the diagnostic module. The host computer then displays the target feedback data, effectively ensuring the security and accuracy of the data upload process. Therefore, this technical solution, through the above methods, can accurately, securely, and efficiently transmit target feedback data to the host computer, enabling accurate analysis of events based on the transmitted data and making the analysis results more realistic and reliable.

This vehicle data processing method can be executed by the vehicle data processing system of the above embodiments. Technical features that are the same as or similar to those in the foregoing embodiments will not be repeated here. Figure 2 As shown, the vehicle data processing method may specifically include:

[0066] S210. The host computer receives a data acquisition request from the target user and sends the data acquisition request to the diagnostic module, wherein the data acquisition request carries the user attribute information of the target user.

[0067] S220. In response to the received data acquisition request, the diagnostic module generates a random key, generates first verification data based on the random key and the user attribute information carried in the data acquisition request, and sends the random key to the host computer.

[0068] S230. The host computer receives the random key sent by the diagnostic module, generates second verification data based on the random key and the user attribute information, and sends the second verification data to the diagnostic module.

[0069] S240. If the first verification data and the second verification data are consistent, the diagnostic module sends the data acquisition request to the EDR control module.

[0070] S250. The EDR control module generates target feedback data corresponding to the data acquisition request, and feeds the target feedback data back to the host computer through the diagnostic module, and displays the target feedback data through the host computer.

[0071] In some embodiments, optionally, generating the target feedback data corresponding to the data acquisition request further includes:

[0072] The data acquisition request is sent to the EDR control module.

[0073] If the EDR control module does not perform the data recording operation for the EDR event, it acquires the collision association data associated with the EDR event and identifies the collision association data as the target feedback data.

[0074] The collision association data includes vehicle association data within a first time period before the target time of the vehicle collision, and vehicle association data within a second time period after the target time. The vehicle association data includes the motion data of the target vehicle and the surrounding obstacle data.

[0075] In some embodiments, optionally, the step of feeding back the target feedback data to the host computer through the diagnostic module and displaying the target feedback data through the host computer includes:

[0076] The first total data volume is determined based on the target feedback data, and the first total data volume is sent to the host computer through the diagnostic module;

[0077] Based on the received first total amount of data, a data upload instruction is generated and sent to the EDR control module through the diagnostic module;

[0078] By responding to the data upload command, the collision-related data associated with the EDR event is obtained, and a preset data upload interface is called to upload the collision-related data to the host computer;

[0079] The second total data volume is determined based on the received collision association data. The first total data volume is compared with the second total data volume. If the second total data volume is consistent with the first total data volume, the collision association data is displayed.

[0080] In some embodiments, optionally, before generating the target feedback data corresponding to the data acquisition request, the method further includes:

[0081] Vehicle operation data of the target vehicle is collected according to preset rules;

[0082] Collision-related data associated with the EDR event are determined from the vehicle operation data, and the collision-related data is stored in the data storage unit.

[0083] In some embodiments, optionally, after determining the collision association data associated with the EDR event from the vehicle operation data, the method further includes:

[0084] The data storage unit is cleared, and the collision-related data associated with the EDR event is stored in the data storage unit.

[0085] In some embodiments, optionally, storing the collision-related data in the data storage unit further includes:

[0086] Based on the data type of the collision association data, the collision association data is preprocessed so that the preprocessed collision association data is stored in the data storage unit.

[0087] In some embodiments, optionally, generating the target feedback data corresponding to the data acquisition request further includes:

[0088] The data acquisition request is sent to the EDR control module;

[0089] If the EDR control module is performing a data recording operation for the EDR event, it will determine the preset prompt information as the target feedback data.

[0090] In the technical solution of this invention embodiment, the host computer receives a data acquisition request from a target user and sends the data acquisition request to the diagnostic module. The data acquisition request carries the target user's user attribute information, enabling authentication based on the data acquisition request to improve the protection of the target feedback data. The diagnostic module, in response to the received data acquisition request, generates a random key and generates first verification data based on the random key and the user attribute information carried in the data acquisition request, and sends the random key to the host computer. Authentication is performed using the generated verification data to ensure the legitimacy of the data acquisition request and improve the protection of the target feedback data. The host computer receives the random key sent by the diagnostic module, generates second verification data based on the random key and the user attribute information, and sends the second verification data to the diagnostic module. Authentication is performed using the generated verification data to improve the protection of the target feedback data. If the first verification data and the second verification data are consistent, the diagnostic module sends the data acquisition request to the EDR control module. This effectively ensures the legitimacy of the data acquisition request and prevents the target feedback data from being leaked or stolen. The EDR control module generates target feedback data corresponding to the data acquisition request and transmits this data to the host computer via the diagnostic module. The host computer then displays the target feedback data, ensuring the accuracy and integrity of the uploaded target feedback data and preventing unauthorized acquisition or tampering. Therefore, this technical solution, through the above method, can accurately, securely, and efficiently transmit target feedback data to the host computer, enabling accurate analysis of EDR events based on the transmitted data, resulting in more reliable and accurate analysis results.

[0091] Example 3

[0092] Embodiment 3 of the present invention provides a flowchart of an optional example of a vehicle data processing method. To better illustrate the technical solution provided by this embodiment, this embodiment uses the following... Figure 3A , Figure 3B and Figure 3C The accompanying drawings illustrate the technical solutions in the embodiments of this application clearly and completely. Specific implementation methods can be found in the description of these embodiments. Technical features that are the same as or similar to those in the foregoing embodiments will not be repeated here.

[0093] The overall implementation of this technical solution can be found in the following example: Figure 3A As shown.

[0094] Step 1: When the host computer receives a data acquisition request for an EDR event from the target user, it sends the data acquisition request to the diagnostic module. Upon receiving the data acquisition request, the diagnostic module generates a random key and calculates the first verification data based on the random key and the data acquisition request. The diagnostic module then sends the random key to the host computer, which calculates the second verification data using a unified security algorithm based on the random key and the data acquisition request. The diagnostic module compares the first and second verification data; if they are the same, it sets the data acquisition request to 1; otherwise, it sets it to 0.

[0095] Step 2: After setting the data acquisition request to 1, the diagnostic module sends a data acquisition request to the EDR control module; the overall implementation logic of Step 2 can be as follows: Figure 3B As shown.

[0096] A. If the EDR system is idle at this time, the EDR control module will send a positive response to the diagnostic module and check whether there is a new EDR event in the data storage unit (an EDR time will be stored once for each emergency braking).

[0097] 1. If a new EDR event exists, the previous EDR event data is deleted, and the target feedback data memory size corresponding to the new EDR event is sent to the diagnostic module. The diagnostic module sends the target feedback data memory size to the host computer. After receiving it, the host computer sends a data upload command to upload the target feedback data memory size, so that the EDR control module calls the preset data upload interface to upload the target feedback data corresponding to the EDR event to the host computer.

[0098] 2. If no new EDR event exists, the system directly checks if an EDR event exists in the data storage unit. If it does, the memory size of that EDR event is sent to the host computer. Based on the data upload command sent by the host computer, the system completes the upload operation for the target feedback data corresponding to the EDR event. It's understandable that when no new EDR event exists, the system still records the closest EDR event. In this case, the closest EDR event can be uploaded again based on the data retrieval request, which can be applied to different users' retrieval requests for the same EDR event.

[0099] B. If the EDR system is recording data for the EDR event at this time, the EDR control module will return a negative response to the diagnostic module. After receiving the negative response, the host computer can continuously send the same data acquisition request to the EDR control module to complete the acquisition of the target feedback data corresponding to the EDR event.

[0100] Step 3: When the upload is complete, the host computer calculates the received data packet memory size L2 and compares it with the data packet memory size L1 sent by the diagnostic module. If L1 = L2, the upload is complete; otherwise, the above steps are repeated. The comparison of data packet memory sizes in Step 3 can be found in... Figure 3C As shown.

[0101] This technical solution, through the above method, can accurately, securely, and efficiently transmit target feedback data to the host computer, thereby enabling accurate analysis of EDR events based on the transmitted data, making the analysis results more realistic and reliable.

[0102] It should be understood that the various forms of processes shown above can be used, with steps reordered, added, or deleted. For example, the steps described in this invention can be executed in parallel, sequentially, or in different orders, as long as the desired result of the technical solution of this invention can be achieved, and this is not limited herein.
