Stabilizer device
First Claim
1. A stabilizer system comprising a stabilizer bar;
- a stabilizer control portion which corresponds to the stabilizer bar and is controllable, based on a running condition of a vehicle, to control an elastic force of the stabilizer bar; and
a control-rule changing portion which changes, when the stabilizer system is brought into an unusual, special state, a control rule according to which the stabilizer control portion is controlled.

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 portion 20 is abnormally fixed to a damping-force producing mode, the rear-wheel-side stabilizer control portion 22 is controlled to the damping-force producing mode. In the case where the front-wheel-side stabilizer control portion 20 is abnormally fixed to an elastic-force producing mode, the rear-wheel-side stabilizer control portion 22 is 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.

14. A suspension system comprising
a stabilizer bar; -
a stabilizer control portion which changes an elastic force of the stabilizer bar;
a different control portion than the stabilizer control portion; and
an abnormality-related rolling-characteristic control portion which controls, when an abnormality occurs to one of the stabilizer control portion and the different control portion, a rolling characteristic of a vehicle, by controlling the other of the stabilizer control portion and the different control portion.

15. A steering-angle-control apparatus for controlling a steering angle of at least one of a front wheel and a rear wheel, based on a state of a steering member that is operated by a driver, the steering-angle control apparatus comprising;
a control-rule changing portion which changes, when an abnormality occurs to a stabilizer control portion which controls an elastic force of a stabilizer bar, a control rule according to which the steering angle of said at least one of the front and rear wheels is controlled.

16. A relative-movement control apparatus for controlling a relative movement of a first member and a second member, the relative-movement control apparatus being provided between the first and second members and being switchable to a relative-movement inhibiting mode in which the relative-movement control apparatus inhibits the relative movement of the first and second members, and a damping-force producing mode in which the relative-movement control apparatus allows the relative movement of the first and second members so as to produce a damping force, the improvement comprising
when an abnormality occurs, the relative-movement control apparatus is switched to a pre-selected one of the relative-movement inhibiting mode and the damping-force producing mode.
