Abstract
Disclosed are various embodiments for calculating or estimating dynamic tire loads from acceleration data. A virtual footprint length can be calculated from acceleration data obtained from the inertial unit of the vehicle. Dynamic tire loads or dynamic vehicle load data can be calculated from the virtual footprint length that is calculated from the acceleration data obtained from the inertial unit.

A method, comprising:
- receiving, from a sensor, a plurality of footprint length measurements for a tire;
- receiving, from an inertial unit, a plurality of acceleration data corresponding to a plurality of axes;
- filtering the plurality of footprint length measurements to remove statistical outlier data samples;
- generating virtual footprint length parameters based upon the plurality of footprint length measurements and the acceleration data;
- and
- generating a virtual footprint length function from which a virtual footprint length of the tire can be calculated from the acceleration data, the virtual footprint length of the tire being calculated without a footprint length measurement from the sensor.
A system, comprising:
- a computing device comprising a processor and a memory;
