Electric power steering apparatus

摘要

An electric power steering apparatus comprising dead zone detecting device for detecting whether a detected value of a steering torque is no more than a predetermined value, that is, in a dead zone or not, steering angular velocity detecting device for detecting the rotation speed of a steering wheel, and motor braking device for braking a motor by short-circuiting the terminals of the motor by the PWM control corresponding to the rotation speed of the steering wheel detected by the steering angular velocity detecting device when the detected value of the steering torque is detected to lie in the dead zone.
