PURPOSE: A system for detecting a wheel track of a vehicle is provided to reliably detect the wheel track by storing an acceleration information during a normal drive and an acceleration information just before and after the accident. CONSTITUTION: A system for detecting a wheel track of a vehicle includes a high frequency filter(20) for filtering a high frequency band by amplifying an analog signal input from an acceleration detector and a low frequency filter(30) for filtering a low frequency band and correcting "0" point displacement. An amplifier(40) removes noise contained in the filtered low frequency and amplifies the same. A first A/D converter(50) converts the amplified analog signal into a digital signal and stores the same in a memory address. A second A/D converter(60) converts the analog signal from the high frequency filter into a digital signal and stores the same in a memory address.
