VEHICLE TAMPERING PROTECTION SYSTEM

摘要

A method of providing a vehicle monitoring system (10) for ensuring accurate vehicle mileage readings is provided. Microprocessor (20) receives data from a data bus (30) and a satellite communicator (40) regarding the current veloci ty of the vehicle. After a duration of relatively stable velocity, a velocity difference is calculated between the vehicle speed signal (36) and the satellite speed signal (43). The velocity difference is compared to an allowable tolerance. The vehicle monitoring system may communicate out of tolerance conditions to the vehicle operator through an instrument display (50) and a fleet manager through a fleet office (60).
