lncreasing ofacting frequency ofpower steering systems in cars causes the difficulties in registering of phenomena proceeding between tire and roadway.Modem sensors give new measuring possibilities, including in their range the frequencies caused by the above mentioned appliances.Increasing of measurements frequency causes increasing of registered signals' noises, limiting signals' legibility.Usage ofsignal filtration multiplies legibility ofaccelerations signals and limits to minimum losing ofessential data contained in the signal.ln this papet there is described the influence of tiltration with Chebyshev tiltet of 4-th and 6-th orders on accuracies of car movement parameters measurements carried out with acceleration sensors and piezo-gyroscopoe.Road tests were verified by measurements of path traveled by car and its instantaneous speed.There were carried aut the signals statistical analysis and determined measuring accuracy of designed appliance basing on comparison of measured path, speed and acceleration values.
