DISPOSITIF DE COMMANDE DE DIRECTION ASSISTEE ELECTRIQUE

摘要

The device has a torque detector (3) detecting deflection torque applied by a driver of a vehicle to electric power steering. A three-phase direct current motor (4) delivers a force of assistance to the steering. An input processing section receives a deflection torque signal from the detector. A processing unit (20) has an applied voltage calculation section to calculate applied voltage on the motor based on the signal and an applied voltage limitation section (23) to limit the voltage to a preset limit value or less than the preset limit value corresponding to the direction of the signal.
