Abstract
A system and method for detecting vehicle movement based on the measurement of the torque value on a vehicle drivetrain is disclosed. The system includes a torque sensor for measuring the torque on a vehicle drivetrain. This measured torque is utilized by a control module, with various other measured vehicle parameters, to determine if the conditions are such that vehicle movement may occur or has already begun. Possible vehicle movement is indicated when either the measured torque value exceeds a threshold value and changes towards zero, or big noise spikes are present in the torque sensor output signal.
