1. A vehicle monitoring system comprising:
- at least one internal sensor on a vehicle, the at least one sensor gathering internal vehicle data;
at least one external sensor on the vehicle, the at least one external sensor gathering external vehicle data;
a processor programmed to compare the internal vehicle data to the external vehicle data.

Abstract
A characterizes vehicle tire and road information using indirect internal vehicle information from emissions, infotainment, and communication subsystems. This approach to characterize vehicle tire and road information eliminates the need for additional sensors within the vehicle or infrastructure, while supporting the analysis across a broad base of existing vehicles. Several examples of this approach are described herein, although other uses could be implemented.
