Patent number: 6550569Abstract: 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.Type: GrantFiled: November 20, 2001Date of Patent: April 22, 2003Assignee: Mando CorporationInventors: Seong Joo Kim, Seong Kyu Kim, Dai Jong Chung, Wan Seop Kim

Patent number: 6505704Abstract: An electric power steering system includes a torque detection unit, an anti-lock brake system electronic control unit (ABS ECU), an electric power steering control unit and an electric power steering motor. The torque detection unit senses a manual steering torque applied to a steering wheel and detects a braking power difference torque. The ABS ECU outputs an ABS operational signal which provides information on a sharp braking operation of the vehicle. The electric power steering control unit generates a motor current in response to the manual steering torque and outputs a modulated motor current if the ABS operational signal is provided. The electric power steering motor reduces unnecessary movements of the steering wheel caused by a difference in road surface frictional forces of the left and the right driving wheels based on the modulated motor current.Type: GrantFiled: September 27, 2001Date of Patent: January 14, 2003Assignee: Mando CorporationInventors: Seong Joo Kim, Seong Kyu Kim, Dai Jong Chung, Wan Seop Kim
