BRIEF DESCRIPTION OF THE DRAWINGS

[0039] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings required for use in the embodiments or the description of the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative work.

[0040] Figure 1 It is a flowchart of a vehicle video recording method according to Embodiment 1 of the present invention.

[0041] Figure 2 It is a specific flow chart of a vehicle video recording method according to Embodiment 1 of the present invention. DETAILED DESCRIPTION

[0042] The following descriptions of the embodiments refer to the accompanying drawings to illustrate specific embodiments in which the present invention may be implemented.

[0043] Please refer to Figure 1 As shown, the first embodiment of the present invention provides a vehicle video recording method, comprising the following steps:

[0044] When a vehicle fault is detected, determine whether there is a corresponding functional safety mechanism for the fault;

[0045] If there is no corresponding functional safety mechanism for the fault, start the off-vehicle video recording;

[0046] If the fault has a corresponding functional safety mechanism, the activation state of the functional safety mechanism and the vehicle safety integrity level to which the functional safety mechanism belongs are further determined, and the outdoor video recording is started or the indoor and outdoor video recordings are started simultaneously according to the determination result.

[0047] It can be seen from the above steps that the present invention realizes vehicle video recording based on functional safety, which not only covers a wider range of scenarios, but also improves the accuracy and applicability of video recording, and effectively avoids the situation where key video data cannot be recorded when an emergency occurs.

[0048] Specifically, please combine Figure 2 As shown, the embodiment of the present invention monitors the fault status of the vehicle in real time through the central control unit (CCU). It can be understood that in modern intelligent vehicle systems, the CCU is mainly responsible for receiving, processing and monitoring various information of the vehicle to ensure the safety and normal operation of the vehicle.

[0049] After the driver takes his seat and starts the vehicle, the vehicle will enter a ready state. At this stage, each system of the vehicle will perform a self-check to ensure that all components are in normal working condition. The CCU's information receiving module begins to receive information from various sensors of the vehicle. This information includes but is not limited to vehicle speed, engine status, battery power, temperature and pressure of various liquids, etc. After receiving this information, the CCU's monitoring module monitors the various states of the vehicle in real time. By comparing the preset safety range with the received real-time data, the monitoring module can quickly detect any abnormalities or faults.

[0050] If the monitoring module detects a fault, it will immediately notify the analysis module. This fault may be an abnormal sensor reading, a component performance degradation, or any other situation that does not meet the preset safety range. The analysis module will perform a functional safety mechanism check, that is, determine whether there is a corresponding functional safety mechanism for the fault.

[0051] It should be noted that the Functional Safety Mechanism is a series of preset response strategies and measures designed to ensure that the vehicle can remain in a safe state when encountering specific faults and avoid unacceptable risks to vehicle safety. The purpose is to reduce or eliminate the serious consequences caused by the fault, thereby protecting passengers, pedestrians and the vehicle itself.

[0052] Functional safety mechanisms usually include the following aspects:

[0053] (1) Fault detection: Ability to identify potentially dangerous faults in the system and provide appropriate responses when faults occur.

[0054] (2) Redundant design: Redundant components or systems are used in critical systems to ensure that when the primary system fails, the redundant parts can take over the functions and maintain safe operation.

[0055] (3) Fault tolerance: Designing the system so that it can enter a safe state when a fault is detected, for example, by limiting vehicle performance to avoid hazardous situations.

[0056] (4) System isolation: Ensure that a fault in one system does not cause dangerous faults in other systems, that is, the fault is isolated within a certain range.

[0057] (5) Diagnostic coverage: Ensure that the system can diagnose and report potential safety issues so that repairs can be performed before the problem becomes serious.

[0058] (6) Safe state: defines the safe state of the system in the event of a fault, which does not increase the risk, such as parking or limiting power output.

[0059] The design and implementation of functional safety mechanisms follow international standards, such as ISO 26262 "Functional Safety of Road Vehicles". This standard defines the Automotive Safety Integrity Level (ASIL), which is divided into four levels: A, B, C and D, according to the risk and severity of potential hazards. D is the highest level, which means the highest level of safety requirements are required.

[0060] In the vehicle video recording of the embodiment of the present invention, the functional safety mechanism involves monitoring the key systems of the vehicle (such as brakes, steering, engine management system, etc.), and triggering video recording when a fault that may affect the safety of the vehicle is detected, so as to analyze and determine the cause of the accident afterwards.

[0061] (I) Processing procedure when there is no corresponding functional safety mechanism for the fault:

[0062] If there is no corresponding functional safety mechanism for the fault, the CCU sends a control command to the Information Domain Controller (IDC). After receiving the control command from the CCU, the IDC system sends a video recording command to the Digital Video Recorder (DVR). After receiving the video recording command from the IDC, the DVR immediately starts the external video recording function and starts recording the environment and conditions outside the vehicle, providing important video evidence for subsequent fault analysis or accident investigation.

[0063] (II) If the fault has a corresponding functional safety mechanism, the following is the processing procedure:

[0064] The CCU first checks whether the functional safety mechanism related to the fault has been activated.

[0065] 1. For the case where the functional safety mechanism is not activated:

[0066] If the corresponding functional safety mechanism is not activated, the CCU sends a control instruction to the IDC. After receiving the control instruction from the CCU, the IDC sends video synchronization recording instructions to the DVR and the Occupancy Monitoring System (OMS) respectively. After receiving the video recording instruction from the IDC, the DVR immediately starts the outdoor video recording function and starts recording the environment and conditions outside the vehicle; after receiving the video recording instruction from the IDC, the OMS immediately starts the indoor video recording function and starts recording the environment and conditions inside the vehicle. In other words, the vehicle needs to record the video inside and outside the vehicle at the same time at this time, so as to analyze the cause of the failure later or for accident investigation.

[0067] 2. For situations where the functional safety mechanism has been activated:

[0068] If the functional safety mechanism has been activated, the CCU's judgment module will further determine the automotive safety integrity level ASIL to which this functional safety mechanism belongs.

[0069] If the ASIL level of the activated functional safety mechanism is C or D (i.e., a level with higher safety requirements), the CCU will issue a control command to the IDC. After receiving the control command from the CCU, the IDC will issue video synchronization recording commands to the DVR and OMS respectively. After receiving the video recording command from the IDC, the DVR immediately starts the external video recording function and starts recording the environment and conditions outside the vehicle; after receiving the video recording command from the IDC, the OMS immediately starts the internal video recording function and starts recording the environment and conditions inside the vehicle. In this way, under high-level safety requirements, as much information as possible about the inside and outside of the vehicle can be collected for subsequent analysis of the cause of the failure or for accident investigation.

[0070] If the ASIL level of the activated functional safety mechanism is A or B (i.e. relatively low safety requirements), the CCU will also send control instructions to the IDC. After receiving the control instructions from the CCU, the IDC only sends a video recording instruction to the DVR. After receiving the video recording instruction from the IDC, the DVR immediately starts the external video recording function and begins to record the environment and conditions outside the vehicle, providing important video evidence for subsequent fault analysis or accident investigation. In other words, under low-level safety requirements, in-vehicle video recording is not necessary, so the OMS will not be started to record in-vehicle video.

[0071] After the video is recorded, the vehicle communication unit T-Box transmits the recorded video data to the remote server (i.e., the cloud) via a wireless network. Users can set up an associated account for the T-Box in the cloud. Once the video is uploaded to the cloud, the system will synchronize it with the account, and users can access and manage these videos on different devices through this account.

[0072] It can be seen from the above that most of the existing driving video emergency recording technologies use G-sensor changes to trigger emergency video recording, manually trigger vehicle APP emergency video recording, voice trigger emergency video recording, and airbag collision signal trigger emergency video recording. The video recording method proposed in the present invention is based on functional safety design and no longer relies on traditional triggering methods. It can realize emergency video recording in more scenarios, thereby improving the reliability and accuracy of video recording.
