Abstract:
A roll control system is provided that includes first and second dampers each having fluid. A pump fluidly interconnects the first and second dampers. A motor is connected to the pump. A controller is in communication with the motor. The controller is configured to command the motor to drive the pump and transfer fluid between the first and second actuators in a desired direction in response to a roll signal. The pump provides fluid from one of the first and second dampers to the other of the first and second dampers in response to being driven by the motor. The roll control system can be used on front and rear axles to provide improved overall stability for the vehicle. In one example, a common motor is used to drive first and second pumps, which are respectively associated with the front and rear axles.
