Title: Vehicle height control system
Inventor: OKIMURA KOTARO
IPC: B60G17/015
Filed: 2020-03-26
Abstract: To improve a vehicle height control system, for example, being the shortening of a time necessary for vehicle height control.SOLUTION: In a vehicle height control system, vehicle height control is sequentially performed stepwise at each wheel of a part of a plurality of wheels. For example, a vehicle height is made to approximate a target vehicle height at each set value one by one at each of a part of the wheels, however, in this case, when a vehicle height difference between a temporary target vehicle height and a final target vehicle height is larger than a second set value which is smaller than a first set width with a vehicle height which is apart from a measurement vehicle height by the first set width as the temporary target vehicle height, the temporary target vehicle height is set as a control target vehicle height, and when the vehicle height difference is equal to, or smaller than the second set value, the final target vehicle height is set as the control target vehicle height. Therefore, when the vehicle height difference between the temporary target vehicle height and the final target vehicle height is equal to, or smaller than the second set value, the number of times of the switching of control objective wheels in the vehicle height control can be reduced compared with the case that the temporary target vehicle height is set as the control target vehicle height, and a time necessary for the vehicle height control can be thereby shortened by an amount of the reduction.SELECTED DRAWING: Figure 5
