Motion Adaptive-EPS Control

Overview 

Motion adaptive-EPS control performs the steering torque correction control coordinated with VSA system for stabilizing 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 sensor and the acceleration sensor. When the system determines that the vehicle behavior is abnormal, the EPS control unit calculates the correction current based on the vehicle behavior and corrects the steering torque.The motion adaptive-EPS control is stopped in the event of failure in the VSA system.

Mitigates Oversteer Control 

When oversteer occurs, it compensates for steering torque to steer in the countersteer direction, and enhances vehicle control.

Mitigates Understeer Control 

When understeer occurs, it compensates for steering torque to control oversteer, then holds the tire grip to enhance vehicle control.

Stabilizes Braking on Road Surfaces With Different Friction Coefficients Control 

When the vehicle behavior is abnormal while braking on an uneven road surface, it compensates for steering torque to enhance vehicle control.
