ABSTRACT:
A stabilizer system including stabilizer control portions which change respective elastic forces of front-wheel-side and rear-wheel-side stabilizer bars. When an abnormality occurs to one of the stabilizer control portions, the other control portion is controlled according to a changed control rule corresponding to the abnormality. In the case where the front-wheel-side stabilizer control portion20is abnormally fixed to a damping-force producing mode, the rear-wheel-side stabilizer control portion22is controlled to the damping-force producing mode. In the case where the front-wheel-side stabilizer control portion20is abnormally fixed to an elastic-force producing mode, the rear-wheel-side stabilizer control portion22is controlled according to a normal control rule. Since the control rule is changed according to the nature of the abnormality, the vehicle can enjoy improved running stability.
