TRACTION CONTROL SYSTEM AND SENSOR UNIT FOR THE SAME |
摘要 |
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). |
