ABSTRACT:
An arrangement of a vehicular suspension system is disclosed in which each drive circuit which outputs a drive current to a corresponding one of the actuators installed on each shock absorber is arranged at a position adjacent to the corresponding one of actuators. Thus, transmission of signals from each drive circuit to the corresponding one of the actuators is unaffected by electrical disturbance. In addition, a length of a wire connected between the corresponding one of the actuators and the drive circuit can be shortened. The generation of noises causing the electromagnetic wave interference can be prevented. In another preferred embodiment, a printed circuit board containing each drive circuit is mounted in a casing of the corresponding one of the actuators of the shock absorbers.
