Honda HR-V: EPS System Description - 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.
