AI Technical Summary

Technical Problem

A failure of the grounding point in the vehicle's power supply circuit can lead to a power outage, which negatively impacts the vehicle's control safety, and there is no effective solution in the current technology.

Method used

By detecting the electrical parameters of the main power supply circuit, the power supply status is determined and the system switches to the redundant power supply circuit when an abnormality occurs. At the same time, a self-repair operation is performed, including loosening and tightening the elastic connectors, to restore the normal power supply of the main power supply circuit.

Benefits of technology

This avoids interruptions in the main power supply circuit, improves vehicle driving safety, and ensures the stability and reliability of the power supply circuit.
