The present invention relates to a level control apparatus for a vehicle, which can adjust the operation speed of a level control cylinder by adjusting hydraulic pressure supplied to the level control cylinder through a level control valve according to the speed of a vehicle. The level control apparatus for a vehicle according to the present invention comprises: the level control cylinder moving up and down by receiving the hydraulic pressure and mounted on at least one lower link, which connects the vehicle and a working machine, to lift the lower link; the level control valve for supplying the hydraulic pressure to the level control cylinder; a tilt sensor installed in the vehicle to detect the tilt of the vehicle; a vehicle speed sensor for detecting the driving speed of the vehicle; and a control unit for controlling the operation of the level control valve according to the tilt value of the vehicle received from the tilt sensor and controlling the opening degree of the level control valve according to the driving speed of the vehicle received from the vehicle speed sensor. Accordingly, the level control apparatus for a vehicle according to the present invention can adjust the operation speed of the level control cylinder by adjusting the hydraulic pressure supplied to the level control cylinder through the level control valve according to the speed of the vehicle, thereby enabling the smooth level operation of the working machine. |
