Title:
STEERING CONTROL DEVICE AND STEERING CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2021/065408
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a steering control device and a steering control method that can reduce the drive load of a driver during low-speed driving. The present invention comprises a calculation device that activates a steering wheel actuator 7 on the basis of the operation amount of a steering 3 to change the steering angle of wheels 11, and calculates the control amount of the steering wheel actuator 7. The calculation device controls the steering wheel actuator 7 by a first gain in which a ratio of the actual steering angle of the wheels 11 to a steering angle δ changes when the steering 3 is turned. Furthermore, when the steering 3 is turned back, the steering wheel actuator 7 is controlled by a second gain different from the first gain.
