Title:
ELECTRIC POWER STEERING DEVICE, CONTROL DEVICE USED IN ELECTRIC POWER STEERING DEVICE, AND CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2021/029328
Kind Code:
A1
Abstract:
A processor according to an embodiment executes: acquiring a steering torque detected by a steering torque sensor and a vehicle speed detected by a vehicle speed sensor; changing a gain and a phase applied to the steering torque according to a steering frequency when a driver steers a steering wheel; determining the magnitude of an assist torque on the basis of the steering torque and the vehicle speed to which the gain and the phase are applied; and generating, on the basis of the determined assist torque, a torque command value used to control the driving of a motor.
