Abstract
A steered shaft of a steered mechanism is rigidly fixed to a vehicle body. Steering-stiffness is reduced by a lowpass filter for filtering a steered angle detected by a steered angle sensor. A deviation between a target steered angle and the filtered steered angle detected by the steered angle sensor is input to a PID control unit. A gain setting unit sets each of gains for PID control at a low value to thereby reduce steering-stiffness. The PID control unit outputs a target current. A drive circuit performs, e.g., PID control of the steering actuator.
