AI Technical Summary
When a vehicle is equipped with both front-wheel steering and rear-wheel steering systems, a malfunction in the front-wheel steering system can cause the vehicle to lose its steering ability, increasing the probability of accidents and threatening driving safety.
In the event of a front-wheel steering system failure, the rear-wheel steering system drives the rear wheels to rotate based on sensor signals from the front-wheel steering system, maintaining the vehicle's steering capability and ensuring that the driver's steering intentions are realized.
It effectively avoids collisions with other vehicles during subsequent driving, ensures the driving safety of electric vehicles, and improves the consistency of the driver's control logic and the safety of the vehicle.
