[0023] In order to make the purpose, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present disclosure.

[0024] In the related technologies, DVR is becoming more and more popular in automobiles. Before the electrification and intelligence of automobiles, most cars used external independent DVR settings due to the limitations of the hardware capabilities of the automobile's own on-board system, but the reliability of external independent DVRs is often criticized by users. With the development of automobile electrification and intelligence, the hardware performance of the automobile's own on-board system has rapidly improved, and some built-in DVR solutions have begun to appear. The built-in DVR solution can reuse the on-board camera as a data source. With the powerful encoding capability of the on-board system and the rich body information obtained by the on-board system, it can provide users with a better experience.

[0025] In related technologies, the vehicle computer system is generally composed of a high-reliability instrument system (such as a real-time operating system) and a feature-rich entertainment system. The DVR function of the vehicle computer is usually developed on the vehicle's entertainment system because of file storage, network transmission, and development efficiency. In some actual work scenarios, the vehicle's entertainment system carries too many entertainment tasks, which may cause various problems such as freezes, DVR application crashes, encoder abnormalities, and file input and output abnormalities.

[0026] In view of this, one or more embodiments of the present disclosure can jointly complete the encoding and packaging of camera data based on a highly reliable vehicle instrument system and a multifunctional vehicle entertainment system, thereby improving the stability and reliability of the driving recording function.

[0027] See also Figure 1 A driving recording method provided in an embodiment of the present disclosure can be applied to a vehicle instrument system and may include the following steps.

[0028] S1: Acquire and encode video data to generate encoded data.

[0029] In this embodiment, the camera data can be obtained through the vehicle-mounted camera device as the data source of the driving record. Subsequently, the vehicle instrument system can select a preset encoding standard (such as H.264 encoding, H.265 encoding, VP9 encoding, etc.) to encode the acquired camera data to form encoded data. Encoding the camera data can compress the data size and reduce the demand for storage space; it can improve the efficiency of data transmission; it can also adapt to the vehicle environment, such as jitter and rapid movement during vehicle driving, to ensure the stability and reliability of the data.

[0030] S2: Distribute the encoded data to a vehicle entertainment system so that the vehicle entertainment system encapsulates the encoded data.

[0031] In this embodiment, the encoded data is a kind of video data, which can be further encapsulated by the vehicle entertainment system to form a target file (such as MP4 file, MOV file, AVI file). The encapsulation process is an important part of video production and distribution, which can ensure the availability and accessibility of video content. The target file can be a widely supported multimedia container format, which can contain video, audio, subtitles and metadata, and can be compatible for playback on multiple devices and platforms. By utilizing the rich functional characteristics of the vehicle entertainment system, the encoded data is encapsulated, which is conducive to the management and call of driving record data.

[0032] S3: Distribute the encoded data to a backup module, so that the backup module caches the encoded data.

[0033] In this embodiment, the coded data can be distributed not only to the vehicle entertainment system for packaging, but also to the backup module for caching. The backup module can be a submodule included in the vehicle entertainment system, or a module of other devices that the vehicle entertainment system can access and manage. By caching the coded data in the backup module, the coded data is backed up to a certain extent to prevent data loss in unexpected situations.

[0034] In some embodiments, after receiving the coded data, the backup module can cache the coded data in a buffer queue. The length of the buffer queue can be configured according to actual needs. When the data in the buffer queue is full, when new coded data arrives, the backup module can delete the oldest coded data from the buffer queue and store the new coded data in the buffer queue. According to the set length of the buffer queue, the buffer queue can store coded data of a specified time length before the current moment. For example, if the length of the buffer queue is set to 1200, if the frame rate of the coded data is 30fps, 40s of coded data can be cached.

[0035] S4: Monitoring status information reported by the vehicle entertainment system.

[0036] In this embodiment, the vehicle entertainment system can send some status information to the vehicle instrument system. In this way, the vehicle entertainment system can indicate the correct operation of its own system and the correct operation of related application functions in the system. The status information reported by the vehicle entertainment system can be reported according to a predetermined time period. For example, the vehicle entertainment system can periodically send heartbeat information to the vehicle instrument system. If the heartbeat information is interrupted, it can be considered that the vehicle entertainment system has crashed or is stuck. The status information reported by the vehicle entertainment system can also be reported immediately after a predetermined event is triggered. For example, the vehicle entertainment system can immediately send a warning message to the vehicle instrument system when the encapsulation of coded data fails. Through this warning message, it can be reflected that the coded data is received incorrectly, the coded data cannot be encapsulated, and the target file formed by the encapsulated coded data is abnormal.

[0037] S5: When the status information indicates that the encapsulation function of the vehicle entertainment system for the coded data is abnormal, storing the coded data cached in the backup module.

[0038] In this embodiment, when the encapsulation function of the vehicle entertainment system for the coded data is abnormal, the vehicle instrument system can store the coded data cached in the backup module in time. Using the stored coded data, the data can be retrieved and restored when the vehicle entertainment system returns to normal.

[0039] Specifically, the vehicle instrument system can monitor and analyze abnormal information reported by the vehicle entertainment system. When abnormal information occurs and it is determined that data loss may occur, the vehicle instrument system can command the backup module to write the cached encoded data to a preset data storage area (such as a preset disk space).

[0040] It should be noted that the coded data distributed to the backup module after an exception occurs will also be stored in a pre-set data storage area until the exception is resolved, and the file writing operation on the cached data in the backup module will not be stopped.

[0041] In some embodiments, the status information reported by the vehicle entertainment system includes first status information and second status information. If the first status information reported by the vehicle entertainment system is monitored, the coded data cached in the backup module is stored to generate a first emergency file. The first status information may indicate that the encapsulation function of the vehicle entertainment system for the coded data is abnormal. If the second status information reported by the vehicle entertainment system is monitored, the first emergency file is sent to the vehicle entertainment system for encapsulation. The second status information may indicate that the encapsulation function of the vehicle entertainment system for the coded data has returned to normal.

[0042] Specifically, the first status information may indicate a system crash or freeze of the vehicle entertainment system, or an application function abnormality in the system, such as an error in receiving coded data, failure to encapsulate coded data, or an abnormality in the target file formed by encapsulating coded data. When the first status information is detected, the vehicle instrument system needs to save the coded data in the current backup module and the coded data that subsequently enters the backup module to generate a first emergency file.

[0043] When the vehicle entertainment system and the application functions within the system resume normal operation, the vehicle instrument system can resend the coded data stored in the first emergency file to the vehicle entertainment system for packaging and processing. Optionally, when the coded data in the first emergency file is processed by the vehicle entertainment system, the vehicle instrument system can instruct to delete the temporarily stored first emergency file.

[0044] In some embodiments, the status information reported by the vehicle entertainment system includes third status information and fourth status information. If the third status information reported by the vehicle entertainment system is monitored, the encoded data cached in the backup module is stored to generate a second emergency file. The third status information can indicate that the vehicle entertainment system has detected an abnormal vehicle body state. If the fourth status information reported by the vehicle entertainment system is monitored, the second emergency file is sent to the vehicle entertainment system for packaging. The fourth status information can indicate that the vehicle entertainment system has detected that the vehicle body state has returned to normal.

[0045] Specifically, the third state information may indicate abnormal vehicle body information such as collision, side sliding, emergency stop, etc. When the third state information is detected, the vehicle instrument system needs to save the coded data in the current backup module and the coded data subsequently entered into the backup module to generate a second emergency file.

[0046] When the vehicle body returns to normal, the vehicle instrument system can resend the coded data stored in the second emergency file to the vehicle entertainment system for packaging. Optionally, when the coded data in the second emergency file is processed by the vehicle entertainment system, the vehicle instrument system can instruct to delete the temporarily stored second emergency file.

[0047] In a practical application example, when a vehicle's pre-collision warning occurs, the vehicle entertainment system needs to report this information to the vehicle instrument system in a timely manner. The driving record application of the vehicle instrument system will save the coded data in advance to avoid the driving record video not being stored after the vehicle entertainment system crashes due to a collision.

[0048] See also Figure 2 A driving recording method provided in an embodiment of the present disclosure can be applied to a vehicle entertainment system and may include the following steps.

[0049] S21: receiving coded data distributed by a vehicle instrument system, wherein the coded data is generated by encoding acquired camera data by the vehicle instrument system.

[0050] In this embodiment, the specific process of the vehicle instrument system acquiring and encoding the camera data is described in the above step S1, which will not be repeated here.

[0051] S22: Encapsulate the encoded data to generate a target file.

[0052] In this embodiment, the encoded data is a kind of video data, which can be further encapsulated by the vehicle entertainment system to form a target file (such as MP4 file, MOV file, AVI file). The encapsulation process is an important part of video production and distribution, which can ensure the availability and accessibility of video content. The target file can be a widely supported multimedia container format, which can contain video, audio, subtitles and metadata, and can be compatible for playback on multiple devices and platforms. By utilizing the rich functional characteristics of the vehicle entertainment system, the encoded data is encapsulated, which is conducive to the management and call of driving record data.

[0053] S23: Reporting status information to the vehicle instrument system, wherein the status information indicates whether the encapsulation function of the vehicle entertainment system for the encoded data is abnormal, so that the vehicle instrument system can store the encoded data cached in the backup module when the status information indicates that the encapsulation function of the vehicle entertainment system for the encoded data is abnormal.

[0054] In this embodiment, for the specific description of the vehicle instrument system reporting the status information, please refer to the relevant description of step S4 above, which will not be repeated here.

[0055] In this embodiment, when the encapsulation function of the vehicle entertainment system for the coded data is abnormal, the vehicle instrument system can be instructed to store the coded data cached in the backup module in time by reporting status information. The stored coded data can be used to retrieve and restore the data when the vehicle entertainment system returns to normal.

[0056] In some implementations, the first state information may be reported to the vehicle instrument system. The first state information may indicate that the encapsulation function of the vehicle entertainment system for the coded data is abnormal, so that the vehicle instrument system can store the coded data cached in the backup module and generate a first emergency file when acquiring the first state information.

[0057] In some implementations, the second state information may be reported to the vehicle instrument system, which may indicate that the encapsulation function of the vehicle entertainment system for the encoded data has returned to normal, so that the vehicle instrument system can send the first emergency file to the vehicle entertainment system for encapsulation when acquiring the second state information.

[0058] Specifically, the first status information may indicate a system crash or freeze of the vehicle entertainment system, or an application function abnormality in the system, such as an error in receiving coded data, failure to encapsulate coded data, or an abnormality in the target file formed by encapsulating coded data. By reporting the first status information, the vehicle instrument system may be instructed to save the coded data in the current backup module and the coded data that subsequently enters the backup module, and generate a first emergency file.

[0059] When the vehicle entertainment system and the application functions within the system resume normal operation, the second status information can instruct the vehicle instrument system to resend the encoded data stored in the first emergency file to the vehicle entertainment system for packaging processing.

[0060] In some implementations, the third state information may be reported to the vehicle instrument system. The third state information may indicate that the vehicle entertainment system detects an abnormal vehicle body state, so that when the vehicle instrument system obtains the third state information, it can store the coded data cached in the backup module and generate a second emergency file.

[0061] In some implementations, the fourth state information may be reported to the vehicle instrument system, which may indicate that the vehicle entertainment system has detected that the vehicle body state has returned to normal, so that when the vehicle instrument system obtains the fourth state information, it can send the second emergency file to the vehicle entertainment system for packaging.

[0062] Specifically, the third state information may indicate vehicle body abnormality information such as collision, side sliding, emergency stop, etc. By reporting the third state information, the vehicle instrument system may be instructed to save the coded data in the current backup module and the coded data subsequently entering the backup module to generate a second emergency file.

[0063] When the vehicle body status returns to normal, by reporting the fourth status information, the vehicle instrument system can be instructed to resend the coded data stored in the second emergency file to the vehicle entertainment system for packaging processing.

[0064] A driving recorder system provided by one embodiment of the present disclosure may include a vehicle instrument system and a vehicle entertainment system.

[0065] The vehicle instrument system can acquire and encode the camera data to generate encoded data; the encoded data can be distributed to the vehicle entertainment system so that the vehicle entertainment system can encapsulate the encoded data; the encoded data can also be distributed to the backup module so that the backup module can cache the encoded data.

[0066] The vehicle entertainment system can receive the encoded data distributed by the vehicle instrument system; and can encapsulate the encoded data to generate a target file.

[0067] In the driving recorder system, the vehicle entertainment system can report status information to the vehicle instrument system. The status information can reflect whether the encapsulation function of the vehicle entertainment system for the coded data is abnormal. The vehicle instrument system can monitor the status information reported by the vehicle entertainment system. When the status information indicates that the encapsulation function of the vehicle entertainment system for the coded data is abnormal, the vehicle instrument system can store the coded data cached in the backup module.

[0068] For a practical example, see Figure 3 The overall design of a driving recorder system is divided into two parts: services running on the vehicle instrument system and services on the vehicle entertainment system.

[0069] Specifically, the service on the vehicle instrument system side completes the following functions: acquiring and encoding camera data; distributing the encoded data to the driving record service on the vehicle entertainment system side; distributing the encoded data to the backup module; and using the status monitoring module to monitor the execution status of the driving record service on the vehicle entertainment system side.

[0070] The service on the vehicle entertainment system side completes the following functions: receiving the coded data distributed by the vehicle instrument system; encapsulating the coded data and saving it as a target file; using the status reporting module to report the heartbeat information of the vehicle entertainment system and the abnormal body information to the vehicle instrument system.

[0071] For a practical example, see Figure 4 ,The driving record system utilizes two subordinate systems and the logic of ,backing up the coded data is as follows.

[0072] The driving record service of the vehicle instrument system will distribute the coded data to the backup module managed by the vehicle instrument system when distributing the coded data to the vehicle entertainment system. After receiving the coded data, the backup module will cache the coded data in the buffer queue. The length of the buffer queue can be configured according to demand. When the buffer queue is full and new coded data arrives, the oldest coded data will be deleted from the buffer queue and the new coded data will be stored. According to the set length of the buffer queue, the buffer queue can store coded data of a specified time length before the current moment. For example, if the length of the buffer queue is set to 1200 and the frame rate of the coded data is 30fps, 40s of data can be cached.

[0073] For a practical example, see Figure 5 ,The driving record system utilizes two subordinate systems and the logic of ,monitoring abnormalities is as follows.

[0074] The status reporting module of the driving record service of the vehicle entertainment system can always report the following information in the background:

[0075] 1. The vehicle entertainment system periodically sends heartbeat information to the vehicle instrument system. If the heartbeat is interrupted, it means that the driving record service on the vehicle entertainment system side has crashed, is stuck, or the entire vehicle entertainment system is stuck.

[0076] 2. The vehicle entertainment system detects whether the coded data is received normally. If the coded data is not received within the specified time (set by the user), a timeout message will be reported to the vehicle instrument system.

[0077] 3. The vehicle entertainment system detects whether the MP4 file generated after encapsulating the encoded data is normal. If the input and output ports of the MP4 file are abnormal, a timeout message will be reported.

[0078] 4. Detect abnormal vehicle body information. For example, when a pre-collision warning occurs, this information needs to be reported to the driving record service of the vehicle instrument system in a timely manner. The driving record service of the vehicle instrument system will save the coded data in advance to avoid crashes that cause the vehicle entertainment system to crash and to avoid driving record data not being stored.

[0079] In this application example, the status monitoring module corresponding to the driving record service of the vehicle instrument system will detect and analyze abnormal information. When abnormal information occurs and it is determined that data loss may occur, the vehicle instrument system will command the backup module to write the backed-up coded data to the disk. After the abnormal information occurs, the coded data distributed to the backup module will also be written to the disk. The file writing operation of the coded data in the backup module will not be stopped until the abnormality is resolved.

[0080] For a practical example, see Figure 6 ,The driving record system utilizes two subordinate systems and the logic of data ,recovery after an abnormal state occurs is as follows.

[0081] After an exception occurs, when the driving record service of the vehicle entertainment system resumes normal operation, the driving record service of the vehicle instrument system will send the coded data saved in the emergency file to the driving record service of the vehicle entertainment system. After receiving the coded data saved in the emergency file, the driving record service of the vehicle entertainment system will extract the coded data, encapsulate it and save it. The logic is as follows:

[0082] 1. After the driving record service of the vehicle entertainment system is normal, it will perform self-check and report system information to the driving record service of the vehicle instrument system.

[0083] 2. The driving record service of the vehicle instrument system will check whether there are emergency files.

[0084] 3. If there is an emergency data file, the driving record service of the vehicle instrument system will send the emergency file to the driving record service of the vehicle entertainment system. After receiving the data in the emergency file, the driving record service of the vehicle entertainment system will encapsulate and save it as an MP4 file.

[0085] 4. The driving record service of the vehicle instrument system will delete the emergency files of the vehicle instrument system after all emergency files have been transmitted and the driving record service of the vehicle entertainment system has processed the data in the emergency files.

[0086] 5. When all emergency documents have been processed, the driving record service of the vehicle instrument system and the driving record service of the vehicle entertainment system will continue the normal driving record process.

[0087] The technical solution provided by one or more embodiments of the present disclosure fully utilizes the high stability of the instrument system and the rich development ecology of the entertainment system without adding additional hardware circuits, and splits the driving record application based on the entertainment system into the instrument system and the entertainment system. The data is backed up in the two systems, which greatly enhances the stability of the driving record application under abnormal conditions.

[0088] According to the technical solution provided by one or more embodiments of the present disclosure, the operations of obtaining and encoding camera data by the driving record application are placed in the instrument system, which is more efficient and occupies less hardware resources than placing them in the entertainment system.

[0089] In one or more embodiments of the present disclosure, the instrument system and the entertainment system have backups for the driving record data. When the entertainment system is abnormal, the instrument system with high feasibility can still save the driving record data.

[0090] According to the technical solution provided by one or more embodiments of the present disclosure, after the abnormality is eliminated and the entertainment system is restored, the backup data of the instrument system can be restored to the entertainment system.

[0091] The technical solution provided by one or more embodiments of the present disclosure can address the file input and output problems caused by the freezing of the entertainment system, the high load of the entertainment system, and the loss of driving record data when the driving record application on the entertainment system side crashes.

[0092] The technical solution provided by one or more embodiments of the present disclosure acquires and encodes the camera data through the vehicle instrument system, making full use of the stability and reliability of the vehicle instrument system to ensure the continuous acquisition of the encoded data; encapsulates the encoded data through the vehicle entertainment system, and utilizes the rich functionality of the vehicle entertainment system to perform various types of processing and calling on the encapsulated encoded data. In addition, the backup module is used to cache the encoded data, so that when an abnormality occurs in the vehicle entertainment system, the cached data can be stored in time to ensure that the encoded data will not be lost, which is conducive to the later data retrieval and recovery.
