Classification: CPC B | IPC B

Claim 6:
7. A vehicle height control method comprising:
acquiring pressure data on a pressure inside an air tank storing compressed air and obstacle data on an obstacle in front of a vehicle;
calculating a target vehicle height based on the obstacle data; and
calculating a required forward-moving distance required for controlling a vehicle height to reach the target vehicle height based on the pressure of the compressed air inside the air tank, determining a vehicle height control timing, and controlling the vehicle height at the vehicle height control timing,
wherein the obstacle data includes a height of the obstacle and a distance from the vehicle to the obstacle, and
the determining a vehicle height control timing includes:
setting a required time to reach the target vehicle height based on the pressure of the compressed air and calculating the required forward-moving distance using the required time and a current vehicle speed of the vehicle;
calculating a difference value between the distance from the vehicle to the obstacle and the required forward-moving distance; and
determining a time point at which the difference value is less than or equal to a threshold distance as the vehicle height control timing.
