AI Technical Summary
During the automobile production process, fault codes left over from speaker testing due to improper installation can lead to diagnostic errors and low production efficiency. Current technology requires waiting for the entire vehicle to go into sleep mode before powering on again for initialization, which is time-consuming.
After the vehicle is powered on, the information central processing module and system-on-a-chip generate pin level control commands to automatically initialize the digital signal processor (DSP) and realize speaker on/off detection, avoiding waiting for the whole vehicle to go into sleep mode.
This reduces speaker on/off diagnostic time, improves production efficiency, avoids diagnostic errors, and enhances overall vehicle production efficiency.
