Title:
CONTROL DEVICE FOR POWER STEERING DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/055805
Kind Code:
A1
Abstract:
Provided is a control device for a power steering device capable of obtaining a stable steering feeling near a stroke end. When, alongside steering operation of a steering wheel, the steering angle approaches a stopper angle, the control device for a power steering device calculates, on the basis of a steering torque signal, a stopper torque, which is steering power in the direction opposite the direction in which the steering angle approaches the stopper angle and calculates, on the basis of the vehicle driving state and the stopper torque, a motor command signal for driving an electric motor.
