In new solutions of anti-lock systems in cars there can be observed the tendency of increasing of their acting frequency. It causes difficulties in registration of phenomena proceeded between a tire and a roadway using traditional measuring systems of which registration frequencies are too small. Quick development of acceleration's micro-sensors and piezo-gyroscopes creates new measuring possibilities including in its range frequencies generated by ABS appliances. Together with measurements frequency increasing there follows increasing of registered signals noises, what caused decreasing of their readability. Counteraction of this disadvantageous phenomenon requires using of signal filtration, which increasing readability of obtained accelerations courses does not cause loosing of important information included in this signal. In this article there is described a new measuring appliance based on acceleration microchips and a piezo-gyroscope cooperating with digital recorder and with original software. Here are shown results of road measuring tests of automobile's kinematical features and described influence of digital filters usage on accuracy of vehicle motion parameters.
