ABSTRACT:
In steering control for individually controlling wheel steering angles α1, α2, α3, and α4of a vehicle in accordance with a condition equation for forming a prescribed mode, one of the condition equation variables is used as a steering command value S. In a process for changing the command value S from a value S1to a value S2, for transitioning the steering angles α1, α2, α3, α4from values [α1, α2, α3, α4]S1corresponding to the steering command value S1, to values [α1, α2, α3, α4]S2corresponding to the steering command value S2, the steering angles α1, α2, α3, α4are changed toward incremental transition steering angles [α1, α2, α3, α4]S1+ΔScorresponding to a steering command value (S1+ΔS), which is the steering command value S1to which an incremental steering command value ΔS has been added. After the steering angles α1, α2, α3, α4reach their incremental transition steering angles and steering angle conformance is detected, the angles are changed toward incremental transition steering angles [α1, α2, α3, α4]S1+nΔScorresponding to a steering command value (S1+nΔS), which is the steering command value to which an incremental steering command value ΔS has been added [n times] in succession. This is repeated as many times as required to change the steering angles α1, α2, α3, α4from [α1, α2, α3, α4]S1to [α1, α2, α3, α4]S2.
