ABSTRACT:
A power steering device uses a control value set in accordance with a vehicle's detected steering torque to control an actuator, which generates steering assistance power. When the vehicle appears to be on a collision course with an obstacle detected in its steering direction, the control value is modified so as to inhibit the steering. The control value after the modification for the steering inhibition is a function of the control value prior to the modification. When the detected value of the steering torque is greater than the preset value, the function is modified such that the degree of steering inhibition is increased by comparison with a situation in which the detected torque is less than the preset value.
