PROBLEM TO BE SOLVED: To effectively avoid the running impossibility of a vehicle.SOLUTION: A vehicle height adjustment device 20 is provided which includes an air supply-discharge unit for supplying-discharging air to left-right air springs 24L and 24R provided respectively in left-right driving wheels 16L and 16R of a vehicle 1. The vehicle height adjustment device 20 further include: a pair of left-right number-of-revolutions sensors 30L and 30R for detecting a number of revolutions of the left-right driving wheels 16L and 16R; a pair of left-right internal pressure sensors 31L and 31R for detecting internal pressure of the left-right air springs 24L and 24R; an idling wheel determination part 41 for determining whether or not any one of the left-right driving wheels 16L and 16L is in an idling state based on a detection value of the number-of-revolutions sensors 30L and 30R and the internal pressure sensors 31L and 31R; and an idling wheel ground-contact control part 42 for causing the driving wheels 16L and 16R determined to be in the idling state to contact with ground by supplying the air to the air springs 24L and 24R of the driving wheels 16L and 16R determined to be in the idling state.
【課題】車両の走行不能を効果的に回避する。【解決手段】車両1の左右駆動輪16L,16Rにそれぞれ設けられた左右エアスプリング24L,24Rに対してエア給排を行うエア給排ユニットを備えた車高調整装置20であって、左右駆動輪16L,16Rの回転数を検出する左右一対の回転数センサ30L,30Rと、左右エアスプリング24L,24Rの内圧を検出する左右一対の内圧センサ31L,31Rと、回転数センサ30L,30R及び、内圧センサ31L,31Rの検出値に基づいて左右駆動輪16L,16Rの何れか一方が空転状態にあるか否かを判定する空転輪判定部41と、空転状態と判定された駆動輪16L,16Rのエアスプリング24L,24Rに対してエアを供給して接地させる空転輪接地制御部42とを備えた。【選択図】図2
