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.

First claim

The invention claimed is:

1. A device for determining when the absolute mileage of a vehicle has been manipulated comprising:
a first sensor for determining a first absolute mileage of the vehicle in accordance with a first method;
a display configured to display the first absolute mileage K1 in the vehicle;
a second sensor for determining a second absolute mileage K2 of the vehicle in accordance with a second method based upon provided satellite navigation data, wherein the second method is difference from the first method;
a storage device configured to store the second absolute mileage in the vehicle; and
a comparator for determining a difference between the first absolute mileage and the second absolute mileage, wherein, when the difference exceeds a prescribed limiting value the comparator generates a warning signal, and stores this warning signal in the storage device.

2. The device according to claim 1 , wherein the display is configured to display the generated warning signal.

3. The device according to claim 1 wherein the limiting value is selected from a range of 10% of K1 to 75% of K1, or measures 20% of K1, 30% of K1, 40% of K1, 50% of K1, or 60% of K1.

4. The device according to claim 1 , wherein the storage devices is inaccessible from an interface for connecting a data system inside the vehicle.

5. The device according to claim 1 , wherein the storage device comprises a code-protected storage device such that the storage device can only be written by the second sensor and can only be read by at least one of the comparator or an external reading device.

6. The device according to claim 1 , wherein the first sensor comprises:
a sensor for acquiring revolution data from at least one of a wheel, a gear or a shaft of the vehicle; and
a calculator for determining a traveled distance based on the revolution data acquired by the sensor; and
an adder for summing the traveled distance to determine the first absolute mileage.

7. The device according to claim 1 , wherein the second sensor comprises a receiver module selected from the group consisting of a GPS receiver, a Galileo receiver and a GLONASS receiver.

8. The device according to claim 1 , wherein the comparator determines the difference D upon starting up of the vehicle.

9. The device according to claim 1 further comprising a transmitter configured to transmit the generated warning signal to a central station.

10. A vehicle in combination with a device according claim 1 .
