ABSTRACT:
An electric power steering device for vehicles comprises an electric motor connected to a steering shaft and serving as a servomotor for producing assisting steering power. Torque sensors are adapted to sense steering torque on the steering shaft. A vehicle speed detecting means is adapted to detect the actual vehicle speed. A controller is adapted to control the state of energization of the electric motor such that the output torque of the motor is changed in accordance with the change in the steering torque on the steering shaft and that the energization of the motor is stopped when the actual vehicle speed is increased beyond a predetermined threshold speed which is adjustable by a vehicle speed setting means such as a variable resistor.
