Abstract
The invention relates to a device for measuring the movement of a self-guided vehicle, that comprises onboard thereof: at least one accelerometer provided with a measurement axis arranged in the longitudinal direction of a potential main rectilinear movement of the vehicle, a first tachometer provided on an axle upstream from the vehicle in the longitudinal direction, a second tachometer provided on a second axle downstream from the vehicle in the longitudinal direction, wherein measure signals from the accelerometer and from the first and second tachometers are supplied to a computing unit. Accordingly, it is advantageously possible to determine the speed and the position of the vehicle on a vehicle route while taking into account an adhesion loss of at least one of the axles as well as an exact slope and turn effect on a vehicle route that does not remain rectilinear and changes horizontally and/or vertically.
