Abstract

An integrated tire monitoring system for an agricultural vehicle control system comprises at lease one sensor integrally coupled to at least one tire on a farm vehicle; an external reader for obtaining tire revolution speed data from the sensor during each revolution of the tire; input means for delivering the tire revolution speed data to a vehicle control unit, the vehicle control unit calculating vehicle speed based on the inputted tire revolution speed data and outputting at least one control signal. The reader may input tire pressure data from the sensor into the vehicle control unit for the calculation of pressure adjusted vehicle speed. The sensor may store tire specific identification data accessible by the external reader and one or more control signals from the vehicle ECU may be used to control speed between a plurality of vehicle wheels; engine speed; wheel slippage; and/or tire air pressure. The vehicle control unit may further evaluate work efficacy of the vehicle based upon the calculated vehicle speed and communicate display data of the results to an operator of the vehicle.
