Load estimation system for a tire

A load estimation system for a tire, the tire including a pair of sidewalls extending to a circumferential tread and supporting a vehicle, the system comprising:

• a sensor being mounted to the tire, wherein the tire is a front tire;
• an inflation pressure of the tire being measured by the sensor;
• a footprint formed by the tread, the footprint including a footprint length, wherein the footprint length is measured by the sensor;
• a processor in electronic communication with the sensor;
• a vehicle loading state estimator in electronic communication with the processor and determining a loading state of the vehicle, wherein the vehicle loading state estimator employs the measured inflation pressure and a ratio of the measured footprint length of the front tire to a second footprint length, wherein the second footprint length is a footprint length of a rear tire, and the loading state of the vehicle distinguishes between an empty, half laden, and fully laden vehicle state;
• an inflation correction factor for at least one of the front tire and the rear tire being determined from the loading state of the vehicle;
• a pressure correction module in electronic communication with the processor, the pressure correction module receiving the measured footprint length, the measured inflation pressure, and the inflation correction factor, wherein the pressure correction module determines an adjusted footprint length;
• a de-noising module in electronic communication with the processor, the de-noising module receiving the adjusted footprint length to generate a filtered footprint length;
• a wear correction module in electronic communication with the processor, the wear correction module receiving the filtered footprint length and correcting for wear of at least one of the front tire and the rear tire to generate a wear-corrected footprint length;
• a load determination model in electronic communication with the processor, the load determination model receiving the wear-corrected footprint length and determining an estimated load on at least one of front tire and the rear tire;
• and
• a vehicle control system in electronic communication with the processor, the vehicle control system receiving the estimated load on at least one of the front tire and the rear tire.
