Method for determining the speed of a vehicle having more than one axle taking into account the interval between two measurements and the distance between the two axles

摘要

The method involves detecting when a first wheel (6) drives over an uneven road surface (4), The first wheel is associated with a first axis (5) of the vehicle (1). The uneven surface is driven over at a first time. It is then detected when a second wheel (4) of the vehicle, associated with a second axle (7), drives over the uneven surface (4) at a second time. The vehicle speed is determined from the time intervals between the first and second times and the distance between the first and second axis. Independent claims also cover an apparatus for carrying out the method.
