ABSTRACT:
A suspension control system for an automotive vehicle is provided which utilizes variable damping force shock absorbers for modifying damping force characteristics. Each of the shock absorbers has an electric motor adapted for varying an effective fluid flow restriction established by an orifice when modifying the damping force characteristics. When the electric motor is energized to initialize an angular position thereof upon starting the suspension control, operating torque of the motor is decreased below a preselected level for reducing reaction force from a stopper when an output shaft of the motor is urged into engagement with the stopper arranged at an original angular position of the motor.
