PURPOSE: A device for controlling the height of a vehicle is provided to control the height of the vehicle only at a straight running by deciding the rotation or the straight driving with a steering angle sensor. CONSTITUTION: A height sensor(10) detects the height of a vehicle between a chassis and a car shaft. A steering angle sensor(20) detects a steering angle according to the movement of a steering wheel. A controller(30) offers a control command to control the height of the vehicle by deciding as a straight driving when the steering angle is under a critical value and over a specific time. An air compressor(40) generates compressed air according to the control command. A control valve(50) passes or isolates the compressed air. An air spring(60) controls the height of the vehicle according to the compressed air. Thereby, the reduction of the safety and the inclination of the height are prevented.
