Abstract:

To provide damper operation for controlling an active roll in a vehicle.

A roll control system including a first damper and a second damper having fluid, respectively, is provided. A pump connects the first and second dampers mutually to let the fluid flow between them. A motor is connected with the pump and is linked to a control device, which is constituted to give orders to the motor, drive the pump, and let the fluid flow in the desired direction by responding to a roll signal between a first actuator and a second actuator. The pump supplies the fluid from either of the first and second dampers to the other of them by responding to the driving by the motor. This roll control system can be used for a front axle and a rear axle to improve the stability of the whole vehicle. In one embodiment, one motor in common is used to drive the first and second pumps accompanying with the front axle and the rear axle, respectively.
