Abstract
A vehicle tire load sensing system includes distance sensors mounted on the vehicle near each tire. The distance sensors generate distance signals representing a distance from the sensor to a track that is left in the soil during forward vehicle travel. Pressure sensors generate tire pressure signals. A temperature sensor senses the ambient temperature. A control unit receives the distance signals, the pressure signals and the temperature signals. The control unit compensates the distance signals as a function of the sensed temperature. The control unit generates filtered distance signals, and determines a tire deflection value from the filtered distance signal. The control unit determines the tire load as a function of the tire deflection value, the pressure signal and stored information relating tire load to tire deflection and tire pressure.
