[0002] With the rapid increase in car ownership, traffic accidents are becoming more frequent. Video footage of emergencies, especially before and after traffic accidents, is crucial for determining the cause of the accident and assigning traffic responsibility.

[0003] Emergency video recording is mostly triggered by changes in acceleration sensor values, manual activation of the vehicle's infotainment app or voice commands, or airbag collision signals. Existing emergency video recording methods are suitable for scenarios involving significant changes in vehicle acceleration or airbag deployment in a collision. Furthermore, during emergencies, due to stress and fear, drivers / passengers are unlikely to manually activate the infotainment app or voice commands to begin emergency video recording, thus limiting the app's effectiveness.

Attached Figure Description

[0039] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0040] Figure 1 This is a flowchart illustrating a vehicle video recording method according to an embodiment of the present invention.

[0041] Figure 2 This is a schematic diagram illustrating the specific process of a vehicle video recording method according to an embodiment of the present invention. Detailed Implementation

[0042] The following description of the embodiments is taken with reference to the accompanying drawings, which illustrate specific embodiments in which the invention can be implemented.

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

[0044] When a vehicle malfunction is detected, it is determined whether a corresponding functional safety mechanism exists for the malfunction.

[0045] If there is no corresponding functional safety mechanism for the aforementioned fault, then start recording external video.

[0046] If a corresponding functional safety mechanism exists for the fault, the activation status of the functional safety mechanism and the vehicle safety integrity level to which the functional safety mechanism belongs are further determined, and external video recording is started or internal and external video recording is started simultaneously according to the determination result.

[0047] As can be seen from the above steps, 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, effectively avoiding the situation where key video data is not recorded when an emergency occurs.

[0048] Specifically, please combine Figure 2 As shown, this embodiment of the invention uses a Central Control Unit (CCU) to monitor the vehicle's fault status in real time. It is understood that in modern intelligent vehicle systems, the CCU is primarily responsible for receiving, processing, and monitoring various vehicle information to ensure the vehicle's safety and normal operation.

[0049] After the driver is seated and starts the vehicle, it enters a "Ready" state. During this phase, all vehicle systems perform self-checks to ensure all components are functioning correctly. The CCU's information receiving module begins receiving information from various vehicle sensors. This information includes, but is not limited to, vehicle speed, engine status, battery charge, and the temperature and pressure of various fluids. Upon receiving this information, the CCU's monitoring module monitors the vehicle's various states in real time. By comparing the received real-time data with preset safety ranges, the monitoring module can quickly detect any anomalies or malfunctions.

[0050] If the monitoring module detects a fault, it will immediately notify the analysis module. This fault could be abnormal sensor readings, a performance degradation of a component, or any other situation that deviates from the preset safety range. The analysis module will then perform a functional safety mechanism check to determine whether the fault falls under the corresponding functional safety mechanism.

[0051] It should be noted that functional safety mechanisms are a series of pre-set response strategies and measures designed to ensure that a vehicle remains in a safe state when it encounters a specific malfunction, avoiding unacceptable risks to the vehicle's safety. The aim is to reduce or eliminate the serious consequences of the malfunction, thereby protecting passengers, pedestrians, and the vehicle itself.

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

[0053] (1) Fault detection: It can identify potential dangerous faults in the system and provide an appropriate response when a fault occurs.

[0054] (2) Redundancy design: Use redundant components or systems in critical systems to ensure that the redundant parts can take over the functions and maintain safe operation when the main system fails.

[0055] (3) Fault tolerance: Design the system to enter a safe state when a fault is detected, for example, by limiting vehicle performance to avoid dangerous situations.

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

[0057] (5) Diagnostic coverage: Ensure the system can diagnose and report potential security issues so that repairs can be carried out before the problems become serious.

[0058] (6) Safety state: Defines the safe state of the system under fault conditions, which does not increase the risk, such as stopping or limiting power output.

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

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

[0061] (a) Procedures for handling faults when no corresponding functional safety mechanism exists:

[0062] If no corresponding functional safety mechanism exists for the fault, the CCU sends a control command to the Information Domain Controller (IDC). Upon receiving the control command from the CCU, the IDC system sends a video recording command to the Digital Video Recorder (DVR). Upon receiving the video recording command from the IDC, the DVR immediately activates its external video recording function, beginning to record the external environment and conditions of the vehicle, providing crucial video evidence for subsequent fault analysis or accident investigation.

[0063] (II) Handling procedures when a corresponding functional safety mechanism exists for the fault:

[0064] The CCU first checks whether the functional safety mechanisms associated with the fault have been activated.

[0065] 1. For cases where functional safety mechanisms are not activated:

[0066] If the corresponding functional safety mechanism is not activated, the CCU sends a control command to the IDC. Upon receiving the control command from the CCU, the IDC sends simultaneous video recording commands to both the DVR and the Occupancy Monitoring System (OMS). Upon receiving the video recording command from the IDC, the DVR immediately activates its external video recording function to begin recording the external environment and conditions; upon receiving the video recording command from the IDC, the OMS immediately activates its internal video recording function to begin recording the internal environment and conditions. In other words, the vehicle needs to record both internal and external video simultaneously for subsequent analysis of the cause of the malfunction or for use in accident investigations.

[0067] 2. For cases where functional safety mechanisms are already activated:

[0068] If a functional safety mechanism has been activated, the CCU's decision module will further determine the Automotive Safety Integrity Level (ASIL) to which this functional safety mechanism belongs.

[0069] If the activated functional safety mechanism belongs to ASIL level C or D (i.e., a higher safety requirement level), the CCU will send a control command to the IDC. Upon receiving the control command from the CCU, the IDC will send simultaneous video recording commands to the DVR and OMS respectively. Upon receiving the video recording command from the IDC, the DVR immediately activates the external video recording function to begin recording the external environment and conditions of the vehicle; upon receiving the video recording command from the IDC, the OMS immediately activates the internal video recording function to begin recording the internal environment and conditions of the vehicle. In this way, under high safety requirements, as much information as possible about the inside and outside of the vehicle is collected for subsequent analysis of malfunction causes or for use in accident investigations.

[0070] If the activated functional safety mechanism belongs to ASIL level A or B (i.e., relatively low safety requirements), the CCU will also send control commands to the IDC. Upon receiving the control commands from the CCU, the IDC only sends video recording commands to the DVR. Upon receiving the video recording commands from the IDC, the DVR immediately activates the external video recording function, beginning to record the external environment and conditions of the vehicle, providing crucial video evidence for subsequent fault analysis or accident investigation. In other words, under low safety requirements, in-vehicle video recording is not necessary, therefore the OMS (Optical Management System) will not be activated for in-vehicle video recording.

[0071] After video recording is complete, the in-vehicle communication unit T-Box transmits the recorded video data to a 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 that account, allowing users to access and manage these videos on different devices using this account.

[0072] As can be seen from the above, most existing emergency video recording technologies for vehicles use G-sensor changes to trigger emergency video recording, manual triggering via vehicle-mounted app, voice triggering, or airbag collision signal triggering. The video recording method proposed in this invention is based on functional safety design and no longer relies on traditional triggering methods. It can record emergency videos in more scenarios, thereby improving the reliability and accuracy of video recording.
