Motion Adaptive-EPS Control: Overview

The motion adaptive-EPS control performs the steering torque correction control coordinated with the VSA system to stabilize the vehicle when the steering is unstable. The EPS system determines the state of the vehicle based on the data calculated by the VSA modulator-control unit, and the data from the yaw rate signal and the acceleration signal. When the system determines that the vehicle behavior is abnormal, the EPS control unit calculates the correction current based on vehicle behavior and corrects the steering torque. The motion adaptive-EPS control is stopped in the event of failure in the VSA system.
