PURPOSE: A height control system of a vehicle is provided to improve the safety of passengers by uniformly maintaining the height of the vehicle. CONSTITUTION: An ECU(Electronic Control Unit) discriminates a normal traveling by detecting signals from a brake operating sensor(3), a brake operation position sensor(5) and a car speed sensor(7). In braking a vehicle, the ECU checks the brake operating sensor(3). In turning off the brake operating sensor(3), the ECU maintains the normal state by operating a discharge solenoid valve(21) and discharging supplied compressed air in a shock absorber(17). The ECU checks a speed of the vehicle. Otherwise, the ECU controls as the normal traveling state by discriminating as the vehicle is completely stopped. The ECU operates a clutch(11) when the speed is not zero. A compressor(13) generates the compressed air by the clutch(11). The brake efficiency is improved by driving the compressor(13) with reserve driving force of an engine(9). The compressed air is stored in an air tank(15). The ECU checks an operation of a brake pedal(1). The ECU operates a solenoid valve(19) when the operation of the brake pedal(1) is over a specific value. A front height of the vehicle is raised by supplying the compressed air into the shock absorber(17) through a pipe(18).
