摘要：
This automotive vehicle power-steering system can positively compensate for resistance to the return of a steering linkage from an operating position to its neutral rest position after the vehicle turns a corner, and can enhance a steerability of the vehicle. The system includes a controller ordering a power-assist actuator to reduced the steering angular deviation of a steering wheel to zero when the controller receives a zero-level signal from a steering torque sensor and non-zero-level signal from a steering angular deviation sensor. The method for the system includes a step of controlling the power-assist actuator to generate a return-assist force counteracting the resistance and variable according to vehicle conditions.
