PROBLEM TO BE SOLVED: To monitor minute change in a wheel state and prevent giving a driver an uncomfortable feeling with respect to controllability and stability even when a difference occurs between states of right and left wheels, in a toe angle variable control type vehicle. SOLUTION: In the rear wheel toe angle variable control type vehicle V, right and left electric actuators 11R, 11L for individually changing toe angles with respect to right and left rear wheels 5R, 5L are provided. The rear wheel toe angle variable control type vehicle V is provided with a yaw rate sensor 14, a lateral acceleration sensor 15 and an electric power detection means 19a for detecting drive electric power of the right and left electric actuators 11 individually. When the right and left rear wheels 5 are changed to toe-in by driving the right and left electric actuators 11, the states of right and left rear wheel tires 4 are determined by a tire state determination part 22, based on detection results of the yaw rate sensor 14, the lateral acceleration sensor 15 and the electric power detection part 19a. In accordance with the determined tire states, control gain of the right and left electric actuators 11 is set by a control gain setting part. COPYRIGHT: (C)2009,JPO&INPIT |
