To accurately correct a wheel diameter of a vehicle by a general-purpose method.SOLUTION: A wheel diameter correction device uses data including right and left wheel angular speeds which are acquired by right and left wheel speed sensors of a vehicle and a vehicle body angular speed at vehicle turning which is acquired by a yaw rate sensor fitted to the vehicle to estimate a wheel diameter of the vehicle on the basis of a simultaneous equation relating to the wheel angular speeds, the vehicle body angular speed and a wheel diameter.SELECTED DRAWING: Figure 3

    【課題】汎用的な手法により、車両の車輪径を精度よく補正できる。【解決手段】車輪径補正装置は、車両の左右の車輪速センサによって得られる左右の車輪角速度と、前記車両に取り付けたヨーレートセンサによって得られる、前記車両の旋回時における車体角速度とのデータを用いて、前記車輪角速度と、前記車体角速度と、車輪径とに関する連立方程式に基づいて、前記車両の車輪径を推定する。【選択図】図3
