Abnormity recording method of vehicle, vehicle-mounted cabin system and storage medium

By using the SOC module in the vehicle to encode abnormal event information into event frames and compress system frames, the problem of existing tools being unable to save critical data in a timely manner is solved. This enables rapid recording of abnormalities and reset of the vehicle cockpit system, reducing storage pressure and impacting user experience.

AI Technical Summary

Technical Problem

Existing tools cannot save critical on-site information in a timely manner when there is a sudden failure of the underlying software, which makes it impossible to resolve after-sales issues. They also occupy a large amount of storage space and rely on cloud statistics, which cannot save effective key data at the moment of failure.

Method used

The SOC module encodes abnormal event information into event frames and compresses system frames into status briefs, which are then transmitted to the microcontroller unit for storage, ensuring a 100% success rate in saving the data. The data is then sent back to the third storage unit when the SOC module restarts, reducing storage pressure and lowering bandwidth costs.

Benefits of technology

It enables rapid recording and reset of the in-vehicle cockpit system after an abnormal event occurs, reducing the impact on user experience, minimizing after-sales issues with no information to analyze, and avoiding reliance on cloud statistics.

Abstract

The embodiment of the invention relates to a vehicle abnormity recording method, a vehicle-mounted cabin system and a storage medium, the vehicle abnormity recording method is applied to the vehicle-mounted cabin system, and the method comprises the steps that when an abnormal event occurs, abnormal event information is coded into an event frame through an SOC module, and the event frame is stored in a first storage unit; reading a system frame representing state information of the SOC module through the SOC module, compressing the system frame into a first state brief report and compressing the event frame into a second state brief report, and transmitting the first state brief report and the second state brief report to a microcontroller unit; storing the received first state brief report and the second state brief report in a second storage unit through the microcontroller unit; according to the invention, after the exception occurs, the exception information can be quickly recorded without occupying a large storage space and depending on the cloud.
