Title:
STEERING CONTROL DEVICE, STEERING CONTROL METHOD, AND STEER-BY-WIRE SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/053368
Kind Code:
A1
Abstract:
The present invention pertains to a steering control device, a steering control method, and a steer-by-wire system. In one embodiment thereof, the steer-by-wire system has a first actuator that applies torque to a steering operation input member and a second actuator that applies steering force to wheels. If a deviation amount of the steering angle of the wheels relative to the operation position of the steering operation input member is not less than an acceptable amount when the system has been turned on, the first actuator is controlled such that the deviation amount decreases when the vehicle speed is not more than a threshold, and the second actuator is controlled such that the deviation amount decreases when the vehicle speed is more than the threshold. Therefore, it is possible to prevent control for adjustment of the operation position and the steering angle from adversely affecting on vehicle maintenance or vehicle travel.
