AI Technical Summary
In existing technologies, the video captured by vehicle cameras during vehicle accidents cannot be obtained quickly and accurately, and due to storage space limitations, it is impossible to fully record the vehicle's operating data and video at the time of the accident, resulting in a lack of objective basis for accident analysis and liability determination.
When a vehicle accident occurs, the accident data recorder (EDR) is triggered to acquire operational data and instruct the video recording module to collect target videos inside and outside the vehicle. After preprocessing using the communication module, the data is merged and sent to the server to form a complete vehicle accident record.
It enables the simultaneous recording of vehicle operation data and video at the time of an accident, improving the objectivity and calculation efficiency of accident analysis and liability determination, and avoiding the tedious process of manually acquiring data separately.

[0038] The present disclosure will now be described in further detail with reference to the accompanying drawings. The same reference numerals in the drawings denote elements that have the same or similar functions. Although various aspects of embodiments are shown in the drawings, they are not necessarily drawn to scale unless specifically indicated otherwise.
[0039] Furthermore, to better illustrate this disclosure, numerous specific details are set forth in the following detailed description. Those skilled in the art will understand that this disclosure can be practiced without certain specific details. In some instances, methods, means, components, and circuits well known to those skilled in the art have not been described in detail in order to highlight the main points of this disclosure.
[0040] like Figure 1 , Figure 2 As shown, this disclosure provides a vehicle accident recording system, including an accident data recorder (EDR), a video recording module, and a communication module, wherein:
[0041] EDR is used to acquire vehicle operating data when the vehicle triggers a target event, and to send an accident occurrence indication to the video recording module.
[0042] The video recording module is used to acquire target videos of the vehicle's interior and / or exterior captured by the vehicle-mounted camera during the corresponding time period, based on the time information in the accident occurrence instruction, upon receiving an accident occurrence instruction.
[0043] The communication module is used to preprocess the running data and target video, and send the preprocessed target data, which is used as a vehicle accident record, to the server.
[0044] According to the embodiments of this disclosure, it should be noted that:
[0045] The EDR, video recording module, and communication module are all located in the vehicle.
[0046] The target event can be understood as any event that endangers vehicle safety, such as a vehicle collision, sudden and violent deceleration of the vehicle, or the deployment of airbags.
[0047] Operational data can be understood as any vehicle data that EDR can acquire, without specific limitations. For example, operational data includes crucial vehicle data such as throttle, brake, vehicle speed, acceleration, and airbag information. Operational data provides information on vehicle dynamic parameters, such as real-time vehicle speed, acceleration, and engine speed within 5 seconds before a collision, helping to reconstruct the vehicle's state at the moment of the accident. Operational data can capture driver actions, including brake pedal travel, throttle opening, steering wheel angle, and gear position, to determine if the driver's actions were compliant. Operational data monitors the status of safety systems, recording seatbelt buckle status, airbag deployment time, and anti-lock braking system intervention timing, assessing the effectiveness of safety measures. Operational data provides environmental and event information, including collision direction and impact intensity data, assisting in the analysis of accident causes.
[0048] The accident occurrence indication triggers the video recording module to acquire and store target videos of the vehicle's interior and / or exterior captured by the vehicle's onboard camera during the corresponding time period. Based on the accident occurrence indication, the video recording module stores the target videos of the vehicle's interior and / or exterior captured by the vehicle's onboard camera during the corresponding time period to prevent them from being periodically deleted or overwritten by other videos.
[0049] The video recording module can be any communication module, controller, or storage chip in the vehicle that has storage capabilities; there are no specific limitations, as long as it can store the target video. An accident notification can also be simultaneously sent to the communication module, enabling the communication module to acquire operational data and the target video.
[0050] The communication module can communicate with the EDR and video recording modules via Ethernet, communication bus, or wireless methods. The communication module also communicates with the server wirelessly. Based on instructions sent by the EDR and video recording modules, the communication module can proactively acquire operational data from the EDR and target video from the video recording modules. Alternatively, based on instructions sent by the EDR and video recording modules, the communication module can control the EDR to send operational data and control the video recording modules to send target video. The EDR and video recording modules can also proactively send operational data and target video to the communication module.
[0051] In some accident analysis processes, it is necessary to understand the external and / or internal environments of the vehicle at the time of the traffic accident. Since vehicle-mounted cameras typically only collect video from inside and outside the vehicle, they cannot quickly and accurately obtain video of the accident. Furthermore, videos from inside and / or outside the vehicle are usually stored for only a short time and are periodically deleted or overwritten by other videos due to storage space and time limitations. Therefore, it is impossible to simultaneously obtain the operational data acquired by the EDR (Electronic Data Recording) module and the target video collected by the video recording module at the time of the traffic accident. According to the technology of this disclosure embodiment, at the same time as the accident, the target video of the vehicle and the operational data collected by the EDR are recorded simultaneously. Using the preprocessing of the communication module, the two are directly merged into complete target data for vehicle accident recording and sent to the server. This allows for a more complete reproduction of the accident situation, providing objective evidence for vehicle accident analysis and liability determination. Moreover, it eliminates the need for manual intervention to separately acquire operational data and target video, improving computational efficiency.
[0052] In one implementation, the video recording module is used for:
[0053] Upon receiving an accident occurrence indication, obtain the time information from the accident occurrence indication.
[0054] Based on the time information, determine the first time period for EDR to acquire runtime data.
[0055] Based on the first time period, determine the corresponding second time period, wherein the second time period includes at least the start and end times of the first time period.
[0056] Acquire target videos of the vehicle's interior and / or exterior collected during the second time period.
[0057] According to the embodiments of this disclosure, it should be noted that:
[0058] The second time period can be the same as or longer than the first time period. At a minimum, the second time period corresponding to the target video must cover the first time period for EDR data acquisition.
[0059] In one implementation, the communication module is used for:
[0060] Based on the time dimension, multiple frames of the running data and the target video are matched and merged into target data. The target data contains all the information of both the running data and the target video.
[0061] The target data, which will be used as a vehicle accident record, will be sent to the server.
[0062] Based on the technology disclosed herein, it should be noted that:
[0063] While sending target data to the server, the communication module can also store the target data so that it can be retrieved later in response to other commands.
[0064] According to the technology of the embodiments of this disclosure, the running data and the target video can be time-aligned to facilitate post-processing such as accident analysis after being sent to the server.
[0065] like Figure 3 As shown, this disclosure provides a method for recording vehicle accidents, applied to a video recording module, the method including:
[0066] Step 301: Upon receiving an accident occurrence indication from the Accident Data Recorder (EDR), acquire the target video footage of the vehicle's interior and / or exterior captured by the onboard camera during the corresponding time period, based on the time information in the accident occurrence indication. The accident occurrence indication is a command generated by the EDR when the vehicle triggers a target event to acquire the vehicle's operational data.
[0067] Step S302: Interact with the communication module to enable the communication module to preprocess the running data and target video, and send the preprocessed target data used as vehicle accident records to the server.
[0068] The EDR, video recording module, and communication module are all located in the vehicle.
[0069] The target event can be understood as any event that endangers vehicle safety, such as a vehicle collision, sudden and violent deceleration of the vehicle, or the deployment of airbags.
[0070] Operational data can be understood as any vehicle data that EDR can acquire, without specific limitations. For example, operational data includes crucial vehicle data such as throttle, brake, vehicle speed, acceleration, and airbag information. Operational data provides information on vehicle dynamic parameters, such as real-time vehicle speed, acceleration, and engine speed within 5 seconds before a collision, helping to reconstruct the vehicle's state at the moment of the accident. Operational data can capture driver actions, including brake pedal travel, throttle opening, steering wheel angle, and gear position, to determine if the driver's actions were compliant. Operational data monitors the status of safety systems, recording seatbelt buckle status, airbag deployment time, and anti-lock braking system intervention timing, assessing the effectiveness of safety measures. Operational data provides environmental and event information, including collision direction and impact intensity data, assisting in the analysis of accident causes.
[0071] The accident occurrence indication triggers the video recording module to acquire and store target videos of the vehicle's interior and / or exterior captured by the vehicle's onboard camera during the corresponding time period. Based on the accident occurrence indication, the video recording module stores the target videos of the vehicle's interior and / or exterior captured by the vehicle's onboard camera during the corresponding time period to prevent them from being periodically deleted or overwritten by other videos.
[0072] The video recording module can be any communication module, controller, or storage chip in the vehicle that has storage capabilities; there are no specific limitations here, as long as it can store the target video.
[0073] The communication module can communicate with the EDR and video recording module via Ethernet, communication bus, or wireless methods. It also communicates with the server wirelessly. Based on instructions sent by the EDR and video recording module, the communication module can actively retrieve operational data from the EDR and target video from the video recording module. Alternatively, based on instructions sent by the EDR and video recording module, the communication module can control the EDR to send operational data and control the video recording module to send target video.
[0074] In some accident analysis processes, it is necessary to understand the external and / or internal environments of the vehicle at the time of the traffic accident. Since vehicle-mounted cameras typically only collect video from inside and outside the vehicle, they cannot quickly and accurately obtain video of the accident. Furthermore, videos from inside and / or outside the vehicle are usually stored for only a short time and are periodically deleted or overwritten by other videos due to storage space and time limitations. Therefore, it is impossible to simultaneously obtain the operational data acquired by the EDR (Electronic Data Recording) module and the target video collected by the video recording module at the time of the traffic accident. According to the technology of this disclosure embodiment, at the same time as the accident, the target video of the vehicle and the operational data collected by the EDR are recorded simultaneously.

This allows for a more complete reproduction of the accident situation, providing objective evidence for vehicle accident analysis and liability determination. Moreover, it eliminates the need for manual intervention to separately acquire operational data and target video, improving computational efficiency.

[0076] Upon receiving an accident occurrence indication from the accident data recorder (EDR), the time information in the accident occurrence indication is retrieved.
[0077] Based on the time information, determine the first time period for EDR to acquire runtime data.
[0078] Based on the first time period, determine the corresponding second time period, wherein the second time period includes at least the start and end times of the first time period.
[0079] Acquire target videos of the vehicle's interior and / or exterior collected during the second time period.
[0080] According to the embodiments of this disclosure, it should be noted that:
[0081] The second time period can be the same as or longer than the first time period. At a minimum, the second time period corresponding to the target video must cover the first time period for EDR data acquisition.
[0082] like Figure 4 As shown, this disclosure provides a method for recording vehicle accidents, applied to a communication module, the method including:
[0083] Step S401: Acquire vehicle operating data, wherein the operating data is the data acquired by the Accident Data Recorder (EDR) when the vehicle triggers the target event.
[0084] Step S402: Acquire target videos inside and / or outside the vehicle, wherein the target videos are target videos inside and / or outside the vehicle captured by the vehicle camera during the corresponding time period, acquired by the video recording module when it receives an accident occurrence indication sent by EDR, based on the time information in the accident occurrence indication.
[0085] Step S403: Preprocess the running data and target video, and send the preprocessed target data, which will be used as vehicle accident records, to the server.
[0086] According to the embodiments of this disclosure, it should be noted that:
[0087] The EDR, video recording module, and communication module are all located in the vehicle.
[0088] The target event can be understood as any event that endangers vehicle safety, such as a vehicle collision, sudden and violent deceleration of the vehicle, or the deployment of airbags.
[0089] Operational data can be understood as any vehicle data that EDR can acquire, without specific limitations.

Operational data provides environmental and event information, including collision direction and impact intensity data, assisting in the analysis of accident causes.
[0090] The accident occurrence indication triggers the video recording module to acquire and store target videos of the vehicle's interior and / or exterior captured by the vehicle's onboard camera during the corresponding time period. Based on the accident occurrence indication, the video recording module stores the target videos of the vehicle's interior and / or exterior captured by the vehicle's onboard camera during the corresponding time period to prevent them from being periodically deleted or overwritten by other videos.
[0091] The video recording module can be any communication module, controller, or storage chip in the vehicle that has storage capabilities; there are no specific limitations here, as long as it can store the target video.
[0092] The communication module can communicate with the EDR and video recording module via Ethernet, communication bus, or wireless methods. It also communicates with the server wirelessly. Based on instructions sent by the EDR and video recording module, the communication module can actively retrieve operational data from the EDR and target video from the video recording module. Alternatively, based on instructions sent by the EDR and video recording module, the communication module can control the EDR to send operational data and control the video recording module to send target video.
[0093] In some accident analysis processes, it is necessary to understand the external and / or internal environments of the vehicle at the time of the traffic accident. Since vehicle-mounted cameras typically only collect video from inside and outside the vehicle, they cannot quickly and accurately obtain video of the accident.
