Abstract
There is an electric power steering apparatus comprising: an electronic control circuit to output a drive signal having a vehicle velocity response characteristic and steering response characteristic in accordance with the vehicle velocity, steering torque, and steering direction; and a motor for assisting a steering force which is made operative by the drive signal. The electronic control circuit has a braking control circuit to short-circuit between both terminals of the motor when the steering operation is stopped and the supply of the drive signal to the motor is stopped while the vehicle is running at a high speed. With this apparatus, when the steering operation is suddenly stopped when the vehicle is running at a high speed, the inertia rotation of the motor can be rapidly reduced. The yawing of the vehicle body due to the inertia rotation can be effectively prevented.
