AI Technical Summary

Technical Problem

In the prior art, vehicles are prone to instability due to the inner wheel slip rate breaking through the limit when cornering, and the adaptive cruise system cannot cope with driver intervention, especially in new energy vehicles, multi-motor driving methods are not fully utilized.

Method used

By obtaining the vehicle's motion parameters and inherent attribute parameters, the lateral driving torque limit value of the four wheels, especially the braking torque intervention amount of the inner wheel, the brake actuator is used to control the longitudinal force of the inner wheel, limit the slip rate, and prevent the wheel from being subjected to force to break through the limit.

Benefits of technology

Effectively control the stability of the vehicle when cornering, prevent the wheel slip rate from exceeding the limit, and ensure vehicle safety and driving stability.
