Abstract
A device for determining if the absolute mileage of a vehicle has been manipulated is disclosed. The device includes a first sensor to determine a first absolute mileage of the vehicle and a second sensor to determine a second absolute mileage of the vehicle. The first and second sensors differ in terms of the sensor and computing method for determining the first and second absolute mileage. For example, the first sensor may be a convention mileage device and the second sensor may be a GPS-enabled device. A comparator determines a difference between the first and second absolute mileage. If the difference exceeds a prescribed limiting value, the comparator generates a warning signal, and stores this warning signal in the storage device. A display is used to display the first absolute mileage in the vehicle.
