PURPOSE: A control method of a vehicle wheel is provided to reduce deviation between a measure speed and an actual speed by sensing the speed of a vehicle wheel using a waveform with two or more cycles. CONSTITUTION: A waveform generated by the rotation of a tone wheel(40) is inputted for a preset cycle. A speed of a vehicle wheel is calculated by using the waveform with two or more cycles when the edge of the waveform is smaller than a reference number. The edge data of the waveform is obtained for the preset cycle. The edge data includes falling time data and rising time data of the waveform. |
