Claims

[Scope of Utility Model Registration Claim] (a) Vehicle height detection means for detecting the actual vehicle height of a plurality of wheel parts; (b) Detecting the first part of the plurality of wheel parts to complete vehicle height adjustment first. (c) prediction means for predicting the amount of change in vehicle height of the first-arriving part after the adjustment is completed, which changes in accordance with the vehicle height adjustment change of the second-arriving part other than the first-arriving part; (d) a predetermined (e) a target setting means for setting a target vehicle height, and correcting the target vehicle height of the first arrival part in a direction to cancel the predicted value according to the predicted value from the prediction means; a calculation means for calculating a vehicle height control value for each wheel part in a direction that reduces the deviation based on the deviation between the target vehicle height and the actual vehicle height of each of the plurality of wheel parts; (f) a calculation result of the calculation means; A vehicle height control device comprising: adjustment means for independently adjusting the vehicle height of a plurality of wheel parts based on the following.
