    • Provided are a traction control system for readily and highly accurately detecting acceleration occurring in up/down, forward/backward, and left/right directions of a wheel to perform drive control of a vehicle and a sensor unit for the traction control system. A sensor unit (100) having an acceleration sensor is provided on a rotating body of a rotation mechanism section including each tire (300), and the acceleration sensor detects acceleration occurring as a tire (300) rotates, the acceleration occurring in X, Y, and Z directions including the rotating direction of the tire. The detected result in digital values is sent as digital information by an electromagnetic wave. The digital information is received by a monitor device (200) provided on each tire house, and acceleration values obtained through calculation are outputted to a drive control unit (700). The drive control unit (700) estimates the amount of strain of each tire (300) based on the obtained acceleration value and strain characteristics information memorized in advance, and the drive control unit (700) controls a sub-throttle actuator (412) to drive a sub-throttle (416) based on the estimated amount of tire strain and the result of detection of the rotational speed of each tire (300).
    • 提供了一种牵引力控制系统,用于容易且高精度地检测发生在车轮的向上/向下,向前/向后和向左/向右方向上的加速度,以执行车辆的驱动控制和用于牵引力控制系统的传感器单元。 具有加速度传感器的传感器单元(100)设置在包括轮胎(300)的旋转机构部的旋转体上,加速度传感器检测轮胎(300)旋转时的加速度,X,Y ,Z方向包括轮胎的旋转方向。 数字值的检测结果通过电磁波作为数字信息发送。 数字信息由设在每个轮胎车间的监视器装置(200)接收,并且通过计算获得的加速度值被输出到驱动控制单元(700)。 驱动控制部(700)基于所获得的预先存储的加速度值和应变特性信息来估计每个轮胎(300)的应变量,驱动控制部(700)将副节气门执行机构(412)控制为 基于估计的轮胎应变量和每个轮胎(300)的旋转速度的检测结果来驱动副节气门(416)。
