Patent ID: 8055423

Claim:
A motor vehicle drive control system providing control means which drives each drive actuator of an engine throttle, a steering, and brakes according to detection result of operation states of a motor vehicle to perform stability control at the time of motor vehicle traveling, comprising: a plurality of sensor units which are provided in the front and rear, and left and right of a motor vehicle body respectively, wherein the sensors are arranged to detect a first acceleration generated in a fore-and-aft direction of the motor vehicle body, a second acceleration generated in a left-and-right direction of the vehicle body, and a third acceleration generated in an up-and-down direction of the motor vehicle body, to convert the detection result into digital values, and transmit digital information including the digital values; and a monitoring device which receives the digital information transmitted from the sensor units, and acquires the detection result of the first to third accelerations of every sensor unit, wherein the control means has means of performing correction control of drive of a predetermined drive actuator among the respective drive actuators on the basis of the detection result of the first to third accelerations acquired by the monitoring device, wherein a sensor unit is provided in each of a plurality of bodies of rotation, which are the wheels or which are bodies of rotation provided in a motor vehicle body side for mounting the wheels, and rotates with the respective wheel, and wherein each sensor provided in a body of rotation is arranged to detect accelerations in three mutually orthogonal directions, being (i) a rotary direction of the tire of the respective wheel, (ii) a direction of the axis of rotation of the respective wheel and (iii) a direction orthogonal to the axis of rotation of the respective wheel.
