Problems solved by technology

[0005] The air suspension adjusts the vehicle height (vehicle height) by utilizing the compressed air stored in the air tank, which causes the vehicle height control speed to vary according to the pressure of the air remaining in the air tank, and therefore, will be later or earlier than The vehicle height needs to be controlled at the point of time when the vehicle height needs to be controlled, thus reducing the ride comfort

Abstract

The invention relates to an apparatus and method for controlling height of a vehicle. The apparatus includes an information acquisition device that acquires pressure data on a pressure inside an air tank storing compressed air and obstacle data on an obstacle in front of a vehicle, and a controller that calculates a target vehicle height based on the obstacle data, calculates a required distance required to reach the target vehicle height based on the pressure of the compressed air inside the air tank, and determines a vehicle height control timing, thereby resolving a problem that the vehicle height is unnecessarily quickly controlled compared to the position of the obstacle, or is controlled after the vehicle passes through the obstacle to reduce the ride comfort.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of priority to Korean Patent Application No. 10-2020-0073108 filed in the Korean Intellectual Property Office on June 16, 2020, the entire contents of which are hereby incorporated by reference. technical field [0003] The present invention relates to a device and method for controlling vehicle height. Background technique [0004] In order to improve the ride comfort of users riding in vehicles, the role of suspension is emerging, which can support stable and comfortable driving regardless of road conditions. Generally, when the vehicle is running, the suspension utilizes springs to dampen vibrations or shocks transmitted from the road surface. In recent years, there has been a growing trend to install air suspension, which has improved performance compared to existing suspensions. [0005] The air suspension adjusts the vehicle height (vehicle height) by utilizing the compressed...
