PROBLEM TO BE SOLVED: To make it possible to detect a ground non-contact wheel without giving an influence onto vehicle behavior.SOLUTION: In a wheel condition determination treatment according to one embodiment of the present invention, a ground non-contact wheel estimation part 5a estimates a ground non-contact wheel candidate based on the detection result of a load sensor 2, and a ground non-contact wheel determination part 5b applies a driving force of a prescribed value or lesser, which does not give an influence onto vehicle behavior, to a wheel estimated as a ground non-contact wheel candidate estimated by the ground non-contact wheel estimation part 5a. In the case that a wheel is rotated in association of application of the driving force, it is determined that the wheel is a ground non-contact wheel. Thus, a ground non-contact wheel can be detected without giving an influence onto vehicle behavior.SELECTED DRAWING: Figure 1
【課題】車両挙動に影響を与えることなく不接地車輪を検出すること。【解決手段】本発明の一実施形態である車輪状態判定処理では、不接地車輪推定部5aが、荷重センサ2の検出結果に基づいて不接地車輪候補を推定し、不接地車輪判定部5bが、不接地車輪推定部5aによって不接地車輪候補と推定された車輪に車両挙動に影響を与えない所定値以下の駆動力を付与し、駆動力の付与に伴い車輪が回転した場合、その車輪を不接地車輪と判定する。これにより、車両挙動に影響を与えることなく不接地車輪を検出することができる。【選択図】図1
