Patent ID: 10052948

Abstract:
Embodiments of the present invention provide a motor vehicle controller comprising a computing device, the controller being configured to command a first releasable torque transmitting device of a drive-line to switch between a released condition in which a first releasable torque transmitting device substantially prevents transmission of torque from an input to an output portion thereof, and an engaged condition in which a releasable torque transmitting device allows torque transmission from an input portion to an output portion thereof. The controller may be configured to receive information indicative of: a speed of wheels of a first axle; a speed of wheels of a second axle; and a terrain over which a vehicle is driving. The controller may be configured, in response to a detected disparity between the speed of wheels of said first and second axle when said first releasable torque transmitting device is switched to said engaged condition, in dependence upon said received information indicative of the terrain over which the vehicle is travelling, either: output a signal to automatically cause said first releasable torque transmitting device to perform a reconnect operation comprising momentarily resuming the released condition, and then subsequently resuming the engaged condition, or maintain said first releasable torque transmitting device in said engaged position.
