Abstract

The paper investigates the possibility of using the vibration signals of a vehicle to measure its speed. The principle of the method, the properties of the solution and some validation experimental results are presented. The method proves to be reliable, with a fair maximum error, but only works in some restrictive conditions: enough pavement excitation and a minimum speed of 20km/h. Fortunately, these conditions are satisfied by the system intended to use this method, which aims at diagnosing the pavement and the vehicle itself, while running at traffic speed.
