System and device with vertical and rotary wheel-velocity-measuring for determining vehicle displacement

摘要

A device for determining the displacement of a vehicle on wheels which are connected to a body via a wheel suspension. The device includes apparatus for measuring a quantity which is indicative of the instantaneous vertical velocity of a wheel relative to the body. Using this quantity, the vertical component of the wheel displacement is eliminated so that in the event of a bumpy road surface a higher accuracy is obtained for determining the displacement of the vehicle body.
