VEHICLE DRIVELINE CONTROL SYSTEM AND METHOD, AND MOTOR VEHICLE COMPRISING SUCH A SYSTEM

摘要

A control system for a vehicle operable to control a driveline of a vehicle to vary and amount of torque coupling between first and second groups of one or more wheels, the control system being operable automatically to cause application of brake torque to a wheel of the first or second groups of one or more wheels in response to detection of loss of traction of one or more wheels, wherein if the amount of brake torque or brake pressure of a braking system employed to apply the brake torque exceeds a threshold value in response to the detection of loss of traction, the control system is operable to cause the driveline to reduce the amount of torque coupling between the first and second groups of wheels.

1. A system for a vehicle, the system being operable to:
control a driveline of a vehicle to vary an amount of driveline torque coupling between first and second groups of one or more wheels; and in response to a detection of a loss of traction of one or more wheels cause a stability control system to apply a brake torque to a wheel of the first or second groups of one or more wheels in order to induce a corrective yaw to the vehicle to maintain an intended path of travel; wherein the system is configured such that, when the brake torque applied and/or a brake pressure of a braking system employed to apply the brake torque exceeds a non-zero threshold value, the system causes the driveline to reduce the amount of driveline torque coupling between the first and second groups of wheels.
