PROBLEM TO BE SOLVED: To measure the slip ratio of a tire when a car body travels on a road surface.SOLUTION: A slip ratio measurement device (10) includes: a plate (14) buried in a road surface (22) with which a tire (12) comes into contact; at least three or more load sensors (16) for measuring the load acting on the plate (14); and wheel speed measuring means for measuring the wheel speed of the tire. This slip ratio measurement device (10) can determine a tire load center of gravity (G) and a locus (GT) of the tire load center of gravity, and, on the basis of them, can determine the ground speed and slip ratio.SELECTED DRAWING: Figure 1
【課題】車体が路面走行の際のタイヤのスリップ率を計測する。【解決手段】スリップ率計測装置(10)は、タイヤ(12)が接地する路面(22)に埋設されるプレート(14)と、プレート(14)に作用する荷重を計測する少なくとも3以上の荷重センサ(16)と、タイヤの車輪速度を計測する車輪速度計測手段とを備える。このスリップ率計測装置(10)によれば、タイヤ荷重重心(G)及びタイヤ荷重重心の軌跡(GT)を求めることができ、これらから、対地速度及びスリップ率を求めることができる。【選択図】図1
