Electric power steering system for vehicles
An electric power steering system for vehicles is described comprising: an input shaft operatively connected to a steering wheel; an output shaft operatively connected to a steered wheel; an electric motor for operatively supplying auxiliary torque to the output shaft; steering torque detection means for detecting steering torque acting on the input shaft; driving control means for feeding the electric motor with a motor drive signal based on an output signal from the steering torque detecting means; steering angle detection means for detecting a steering angle of the steering wheel; and correction means for gradually decreasing the motor drive signal to reduce the auxiliary torque to be developed at the electric motor, when the steering angle of the steering wheel is detected to be exceeding a predetermined angle by the steering angle detection means, the predetermined angle being slightly less than a maximum steering angle of the steering wheel.
