To restrain a vehicle lower part from interfering with a road surface when adjusting a vehicle height in a vehicle height adjustment device.SOLUTION: A vehicle height adjustment device 10 has a vehicle height adjustment part 46, a prediction part 40 and a vehicle height control part 42. Among these, the vehicle height adjustment part 46 adjusts a vehicle height to either one of a first state and a second state. This first state is a state where the vehicle height is set to a prescribed height, and the second state is a state where the vehicle height is made lower than the first state. The prediction part 40 predicts whether or not a driving battery 24 (a lower part) of a vehicle 12 interferes with the road surface in the second state. The vehicle height control part 42 controls the vehicle height adjustment part 46 so as to take either one of the first state and the second state. When the prediction part 40 predicts interference the driving battery 24 of the vehicle 12 with the road surface, the vehicle height adjustment part 46 limits transfer to the second state from the first state. Thus, the interference of the driving battery 24 of the vehicle 12 with the road surface can be restrained when lowering the vehicle height.SELECTED DRAWING: Figure 2

    【課題】車高調整装置において、車高調整時に車両下部が路面に干渉するのを抑制することができる。【解決手段】車高調整装置10は、車高調整部46と、予測部40と、車高制御部42とを有しており、このうち車高調整部46は、車高を第1状態と第2状態とのいずれか一方に調整する。この第1状態は、車高が所定の高さとされた状態であり第2状態は、第1状態よりも車高が低くされた状態である。予測部40は、第2状態において車両12の駆動用バッテリ24(下部)が路面に干渉するか否かを予測する。車高制御部42は、第1状態と第2状態とのいずれか一方をとるように車高調整部46を制御する。また、車両12の駆動用バッテリ24の路面への干渉が予測部40により予測された際は、車高調整部46が第1状態から第2状態へ移行するのを制限する。したがって、車高を下げた際に車両12の駆動用バッテリ24が路面に干渉するのを抑制することができる。【選択図】図2
