To provide a rotation speed correction apparatus capable of eliminating influence of tire slippage, which changes depending on a wheel torque, from a rotation speed of a driving wheel tire.SOLUTION: Provided is a rotation speed correction apparatus that corrects a rotation speed of a driving wheel tire mounted on a vehicle, and includes a rotation speed obtainment unit, a comparative value calculation unit, a torque obtainment unit, and a rotation speed calculation unit. The rotation speed obtainment unit obtains the rotation speed of the driving wheel tire and a rotation speed of a following wheel tire mounted on the vehicle. The comparative value calculation unit calculates a comparative value between the rotation speed of the driving wheel tire and the rotation speed of the following wheel tire on the basis of the rotation speeds of the driving wheel tire and the following wheel tire. The torque obtainment unit obtains a wheel torque. The rotation speed calculation unit identifies a linear relationship between the comparative value and the wheel torque, and on the basis of the rotation speed of the following wheel tire and the linear relationship, calculates a rotation speed of the driving wheel tire in which influence of slippage has been eliminated.SELECTED DRAWING: Figure 3

    【課題】駆動輪タイヤの回転速度からホイールトルクに応じて変化するタイヤのスリップの影響をキャンセルすることができる回転速度補正装置を提供する。【解決手段】車両に装着された駆動輪タイヤの回転速度を補正する回転速度補正装置であって、回転速度取得部と、比較値算出部と、トルク取得部と、回転速度算出部とを備える回転速度補正装置が提供される。回転速度取得部は、駆動輪タイヤ及び車両に装着された従動輪タイヤの回転速度を取得する。比較値算出部は、駆動輪タイヤ及び従動輪タイヤの回転速度から、駆動輪タイヤの回転速度と従動輪タイヤの回転速度との比較値を算出する。トルク取得部は、ホイールトルクを取得する。回転速度算出部は、比較値とホイールトルクとの線形関係を特定し、従動輪タイヤの回転速度及び線形関係に基づいて、スリップの影響がキャンセルされた駆動輪タイヤの回転速度を算出する。【選択図】図3
