1. A system for determining speed of a vehicle having a wheel rotatably mounted thereto for facilitating vehicle movement relative to a road surface, the system comprising:
- a sensor configured for mounting to the wheel, the sensor configured for sensing centripetal acceleration of the wheel and generating a signal indicative of sensed centripetal acceleration, the sensor arranged to wirelessly transmit the signal;
an electronic control unit configured for receipt of data associated with the wheel, the electronic control unit further configured to receive the signal from the sensor mounted to the wheel and determine speed of the vehicle based on the sensed centripetal acceleration from the signal received and from the data associated with the wheel; and
the electronic control unit further configured for receipt of replacement data associated with a replacement wheel substituted for the wheel and operative to determine speed of the vehicle based on sensed centripetal acceleration and on the replacement data.

Abstract
The present invention is a system for determining vehicle speed. The system has a sensor mounted on a wheel rotatably mounted on the vehicle for sensing centripetal acceleration of said wheel. The sensor generates a signal indicative of the sensed centripetal acceleration, and is arranged to wirelessly transmit the signal. The system additionally has an electronic control unit mounted on the vehicle. The electronic control unit is arranged to receive the signal and determine the speed of the vehicle based on the sensed centripetal acceleration.
