Abstract
There is provided a tire ground contact pattern specifying method and an apparatus thereof for specifying a tire ground contact pattern usable to perform the stable control of a running vehicle. Using a sensor unitmounted in each tireof a vehicle, accelerations generated in X, Y and Z directions are sensed and at the same time, a low frequency noise component and high frequency noise component added to the Z axis direction acceleration signal are extracted. Digital values being the sensing result are transmitted as digital information to a monitor deviceby radio wave. The monitor devicecompares many pieces of tire ground contact pattern information preliminarily stored with the digital information to thereby specify a tire ground contact pattern. A stability control unitperforms, based on the acceleration values and the information on tire ground contact pattern obtained, the correction control of driving of a sub-throttle actuatoror a brake drive actuator
