Abstract
A method for operating an automobile electric power steering (EPS) system is provided. Whether or not the automatic adjustment of the steering angle is performed is decided based on a speed of the automobile and a rotational state of each wheel. A cooperative steering angle to cooperate a braking state of the automobile is set based on the decision and the speed of the automobile. A target steering angle is determined to adjust the steering angle based on the cooperative steering angle and a manual steering angle; and a feedback control on the steering angle is performed such that the steering angle of each wheel become to close to the determined target steering angle.
Claims3
A method for operating an automobile electric power steering (EPS) system capable of selectively adjusting a steering angle depending on a braking state of an automobile, comprising the steps of:
- making a decision about whether or not the automatic adjustment of the steering angle is performed based on a speed of the automobile due to the braking state and a rotational state of each wheel;
- setting a cooperative steering angle to cooperate the braking state based on the speed of the automobile and decision about whether or not the automatic adjustment of the steering angle is performed;
- determining a target steering angle for the automatic adjustment based on the cooperative steering angle and a manual steering angle of a steering wheel;
- and
- performing a feedback control on the cooperative steering angle such that the steering angle of said each wheel becomes close to the determined target steering angle.
