1. A method for preventing unintended rolling movement of a motor vehicle, said method comprising the steps of:
- a. sensing whether a drive train of the vehicle is in a non-torque-transmitting mode whereby torque cannot be transmitted between an engine of the vehicle and at least one drive wheel of the vehicle to cause a transfer of power from the engine to the at least one drive wheel, wherein the drive train includes a manually-shiftable transmission and the drive train mode sensing step includes the step of sensing whether the manually-shiftable transmission is in a neutral position;
b. sensing whether speed of movement of the vehicle is less than a predetermined limit speed value;
c. engaging a vehicle braking system to prevent rolling movement of the vehicle when the drive train is in a non-torgue-transmitting mode and the speed of movement of the vehicle is less than the predetermined limit speed value.
