Method of measuring kinematic parameters of a land vehicle, device for implementation thereof and application to a railway vehicle.

摘要

Method and device for measuring the speed and acceleration of a vehicle by a digital method. A clock H delivers slow pulses HL and fast pulses HR. The latter are counted in a time counter CT. Distance pulses V supplied by a tachometric detector TY are counted in a distance counter CD. A gate A1 permits this counting during the presence of a pulse HL. The pulses HR, by virtue of a gate A2, are counted only between the start of the first counted pulse V and the start of the first uncounted pulse V. A processor CN carries out a division in order to supply the speed W. Application to the measurement of speed and acceleration on board vehicles, in particular railway vehicles. IMAGE
