AI Technical Summary

Technical Problem

When individual slave devices in a car audio system fail or are missing, the remaining slave devices become unusable, resulting in low maintenance efficiency.

Method used

Multiple slave devices are detected through the in-vehicle audio system to identify the faulty slave device, and the SLOT configuration file of the normal slave device upstream of the faulty slave device is updated to ensure communication transmission between the master device chip and the normal slave device.

Benefits of technology

Discover faulty slave equipment in a timely manner, improve maintenance efficiency, and ensure the normal operation of normal slave equipment.

Abstract

The present invention discloses a method, device, vehicle, and medium for troubleshooting an in-vehicle audio bus, which is applied to an in-vehicle audio system, wherein the in-vehicle audio system has a master device chip and slave devices connected in series on the audio bus. The method comprises: detecting multiple slave devices to determine the faulty slave device, updating the SLOT configuration file of the normal slave device upstream of the faulty slave device, and performing communication transmission between the master device chip and the normal slave device according to the updated SLOT configuration file. The present invention can detect multiple slave devices through the in-vehicle audio system to determine the faulty slave device, and when an individual slave device is abnormal, it can be discovered in time, thereby improving maintenance efficiency; the present invention can update the SLOT configuration file of the normal slave device upstream of the faulty slave device, and can perform communication transmission between the master device chip and the normal slave device according to the updated SLOT configuration file, thereby not affecting the normal operation of the remaining normal slave devices.
