System and method for monitoring vehicle mass tamper events

摘要

Abstract A system for detecting a mass tamper event affecting a vehicle mass record for a vehicle being monitored includes a body bounce frequency estimator configured to 5 estimate body bounce frequency for the vehicle and a mass estimator configured to k estimate a vehicle mass, m, according to the equation m = -2 where k is a constant Wb relating to a suspension system in the vehicle and Wit is the estimated body bounce frequency. A first comparator compares the estimated vehicle mass value with an alternative vehicle mass value and identifies a mass tamper event when the 10 estimated vehicle mass value differs from the alternative vehicle mass value by more than a pre-determined amount. An interface may be used to communicate mass tamper event data to a remote device. A system and method for recording vehicle mass data are also provided.
