VEHICULAR BEHAVIOR CONTROL DEVICE

PROBLEM TO BE SOLVED: To provide a vehicular behavior control device capable of suppressing a vehicle rolling not attributable to the steering. SOLUTION: A vehicle 10 has a toe rigidity changeable device 200 capable of changing the toe rigidity of a rear suspension 20. The toe rigidity changeable device 200 has a change valve 220, and can employ a first change state in which the toe rigidity is relatively high and a second change state in which the toe rigidity is relatively low by controlling the changing position of the change valve 220. When it is discriminated in the rolling suppressing control that the vehicle 10 is in a rolling state, an ECU 100 controls the change state of the change valve to the second change state. As a result, the toe rigidity of the rear suspension 20 is degraded, and generation of the lateral force in right and left rear wheels is suppressed. By suppressing the lateral force of the rear wheels, the rolling of the vehicle 10 is suppressed. COPYRIGHT: (C)2009,JPO&INPIT
