Title:
MOTORIZED POWER STEERING DEVICE, CONTROL DEVICE USED FOR MOTORIZED POWER STEERING DEVICE, AND CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2021/029330
Kind Code:
A1
Abstract:
In the present invention, a processor executes, in accordance with a program, the following processes: acquiring a steering torque, a vehicle speed, a steering angle, and a motor rotational speed; generating a base assist torque on the basis of the steering torque and the vehicle speed; generating a self-aligning torque compensation torque on the basis of the steering torque, the vehicle speed, the motor rotational speed, and the base assist torque; generating an active return torque on the basis of the vehicle speed and the steering angle; generating a motor loss torque compensation torque on the basis of the motor rotational speed; and generating a torque command value to be used for controlling motor driving, the generation being on the basis of the base assist torque, the self-aligning torque compensation torque, the active return torque, and the motor loss torque compensation torque.
