A system constructed in accordance with the present invention compares the rate of change of the yaw rate and the rate of change of the steering wheel or steering control position. If the steering wheel is turned to the right and the vehicle is in a forward gear, then the vehicle ***yaw rate will go to the right***. If the steering wheel is turned to the right and the vehicle is in reverse gear, the vehicle yaw rate will go to the left. Upon vehicle start up, the direction is set to unknown. Once vehicle speed, steering wheel turn and vehicle yaw reach preselected thresholds, a determination of the vehicle direction can be made by comparing the sign of the steering wheel angle change and the sign of the yaw rate change. If the signs match, then the vehicle is in a forward gear. If the signs do not match, then the vehicle is in reverse.
