REAR WHEEL TOE ANGLE CONTROL DEVICE AND REAR WHEEL TOE ANGLE CONTROL METHOD OF VEHICLE

摘要

PROBLEM TO BE SOLVED: To further improve traveling stability by providing a stable steering operation feeling regardless of a change in a traveling environment such as a rainfall and use of an emergency spare tire. SOLUTION: A parameter having a correlation with tire grip force of a vehicle is detected, and when determining that the tire grip force of the vehicle is reduced by a change in the grip force correlation parameter, a toe angle of right and left rear wheels is controlled in the toe-in direction as compared with nonesuch case.
