Abstract
A vehicle has an engine and an on-board computer that controls the function of the engine. The on-board computer also provides diagnostic information, including instantaneous vehicle speed. The vehicle has an odometer that is present in the passenger compartment. The invention samples the instantaneous vehicle speed from the on-board computer and determines the distance traveled by the vehicle. The sampling rate can be adjusted depending on the speed of the vehicle. The odometer information can be sent off the vehicle by way of a transceiver.
