Vehicle tampering protection system
First Claim
1. A method of providing a vehicle monitoring system for ensuring accurate vehicle distance travel data comprising the steps of:
- recording vehicle odometer data in a wireless communication device;
receiving vehicle velocity data signals from a remote satellite system;
measuring vehicle velocity after a duration of vehicle operation at a substantially stable speed;
calculating a velocity difference between a vehicle velocity measured on-board and a vehicle velocity as determined from data signals received from a remote satellite system; and
communicating any condition whereby an absolute value of said velocity difference is greater than an allowable tolerance.

Abstract
A method of providing a vehicle monitoring system for ensuring accurate vehicle miileage readings. A comparison is made between velocity measurements from several sources to detect unauthorized modifications made to a vehicle in an effort to ensure accurate vehicle odometer readings. The vehicle velocity measured on-board is compared with vehicle velocity data signals received from a remote satellite system in light of an allowable tolerance. The system will detect changes in the vehicle such as tire size or tampering with the vehicles on-board measurement devices. The system may communicate out of tolerance conditions to the vehicle operator and the fleet manager.
