Title:
STEERING CONTROL METHOD AND STEERING CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/075278
Kind Code:
A1
Abstract:
In this steering control method, a front-wheel slip angle is estimated, and: when the road surface on which a vehicle is travelling is a low-μ road surface and the axial force difference between a feedback axial force and a standard axial force or a feedforward axial force is less than a first prescribed value, a steering reaction force based on the feedforward axial force is applied (S6); when the road surface is a low-μ road surface and the axial force difference is greater than or equal to the first prescribed value, a steering reaction force based on the feedback axial force is applied (S9); when the road surface is not a low-μ road surface and the front-wheel slip angle is less than a third prescribed value, a steering reaction force based on the feedforward axial force is applied, (S12); and when the road surface is not a low-μ road surface and the front-wheel slip angle is greater than or equal to the third prescribed value, a steering reaction force based on the feedback axial force is applied (S13).
