ABSTRACT:
There is provided a vehicle drive control system performing the stability control of a vehicle by highly accurately and easily sensing accelerations generated in each tire and sensing a tire ground contact pattern, a sensor unit thereof and a tire. Using a sensor unit100mounted in each tire2of a vehicle1, 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 device200by radio wave. The monitor device200compares many pieces of tire ground contact pattern information preliminarily stored with the digital information to thereby specify a tire ground contact pattern and output the information to a stability control unit700. The stability control unit700performs, based on the acceleration values and the information on tire ground contact pattern obtained, the correction control of driving of a sub-throttle actuator412or a brake drive actuator640.
