Summary:

Recently steering technology focuses on not only driver's convenience, fuel efficiency, environment friendliness but also improved vehicle stability. Therefore Active Front Steering (AFS) has been widely studied as latest technical trend in steering system. This system can enhance vehicle stability by making additional road wheel angle (called superimposed angle') based on the vehicle state information such as vehicle speed, steering angle, yaw rate and lateral acceleration.While occurring superimposed steering angle, driver may feel the reaction torque which is caused from abnormal changes of steering effort with AFS mechanism installed. To solve this problem it is required to reduce steering output load in case of superimposed steering by increasing steering assist of rack assist type electric power steering. This paper describes the control method that is compensated reaction torque. And its effect of compensation is validated from test results
