Method and System for Demonstrating Discrepancies in Speedometers in Vehicles
First Claim
1. Method for demonstrating discrepancies in speedometers in vehicles, comprising the steps:
- a) measuring the speed of the vehicle with an external measuring device,b) sending information about speed from the external measuring device to a receiver in the vehicle;
c) comparing the information of speed received from the external measuring device with information of speed according to the speedometer of the vehicle;
d) making the information about possible discrepancies available to a user.

Abstract
The invention relates to a method and a system to demonstrate discrepancies in the speedometer of a vehicle. In a preferred embodiment, the method and the system further comprise the possibility of adjusting or calibrating the speedometer with the use of demonstrated discrepancies automatically or after approval by the user. The speed of the vehicle is measured with an external measuring device and the information about the speed is sent to a receiver in the vehicle. By comparing received information about speed with information of speed according to the speedometer of the vehicle information about possible discrepancies is made available to a user.

15. A method for demonstrating discrepancies in speedometers in vehicles, where the speed according to vehicle speedometer is compared with the vehicle speed information from a second measuring device, for optionally adjusting the vehicle speedometer to a corrected speed based on the measured speed discrepancies, comprising the steps:
-
a) measuring the speed of the vehicle with an external measuring device, b) continuously sending said measured information about speed from the external measuring device to a receiver in the vehicle, c) comparing said information of speed received from the external measuring device with the information of speed according to the speedometer of the vehicle, d) making available said information about possible speed discrepancies to the vehicle user, and adjusting the speedometer adjustment automatically or by approval by the user, and e) using the information about discrepancy to calculate wear on the tires of a car, motorbike, moped or other vehicle by comparing the discrepancy of the speedometer. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22)
