Document Type and Number:
Japanese Patent JP2962683
Kind Code:
B2
Abstract:
An electric power steering apparatus includes a controller for controlling power assist of an electric motor so as to reduce a manual steering force required of the driver. The controller includes two closed control loops, one operating on the basis of a steering torque and the other on the basis of a differential value of the steering torque. The second closed control loop includes a differential torque compensator for compensating for the differentiated steering torque in such a manner as to increase the proportion of an assist torque developed in accordance with the change of the steering torque while keeping a desired degree of stability of operation of the steering system.
