Integrated torque and roll control system
First Claim
1. A fluid control system for a motor vehicle having at least one drive axle having left and right axle shafts each provided with a wheel mounted thereon, said fluid control system comprising:
- a vehicle torque control system including at least one fluidly operated clutch provided to regulate a drive torque distribution between said wheels of said motor vehicle in order to improve traction and stability of said motor vehicle on a drive surface;
a vehicle body roll control system including at least one fluidly operated force device operatively connecting sprung and unsprung masses of the motor vehicle and provided to tilt a vehicle body relative to a vehicle chassis so as to counteract a rollover-inducing force; and
a common source of a fluid pressure provided to operate both said vehicle body roll control system and said vehicle torque control system;
said torque control system further including a left axle disconnect clutch provided to selectively disconnect a torque transfer from a prime mover of the motor vehicle to the left wheel thereof, a right axle disconnect clutch provided to selectively disconnect a torque transfer from the prime mover of the motor vehicle to the right wheel thereof, and left and right clutch actuators each provided for selectively operating corresponding one of said left and right clutches between a disengaged condition and an engaged condition in response to the fluid pressure from said common source of the fluid pressure.

Abstract
An integrated control system for a motor vehicle including at least one drive axle having left and right axle shafts each provided with a wheel mounted thereon. The integrated control system comprises a vehicle torque control system, a vehicle body roll control system, and a common source of a fluid pressure provided to operate both the vehicle body roll control system and the vehicle torque control system. The vehicle torque control system includes at least one fluid actuated clutch provided to regulate a drive torque distribution between the wheels of the motor vehicle in order to improve traction of the motor vehicle on a drive surface. The vehicle body roll control system includes at least one force device provided to tilt a vehicle body relative to a vehicle chassis so as to counteract a rollover-inducing force.
