ABSTRACT:
A method and system, according to one embodiment of the present invention, provide a means to accurately determine the velocity of a vehicle. An initial estimation of the velocity of the vehicle is calculated based on rates of rotation of a plurality of wheels on the vehicles. If any of the wheels on the vehicle are in a brake control, or traction control, situation, the initial estimation is modified based on an acceleration of the vehicle to generate a modified estimation of the velocity of the vehicle.
