PURPOSE: An apparatus for automatic control of a horizontal state of a vehicle is provided to drive four jacks simultaneously for reducing management time and perform precise control of the horizontal state. CONSTITUTION: An apparatus for automatic control of a horizontal state of a vehicle includes a power supply(116) for generating a predetermined power supply voltage, front left and right jacks(102,108) and rear left and right jacks(104,106) respectively mounted at a corresponding position on a bottom part of the vehicle for supporting the vehicle, a sensor box(114) having sensing elements respectively sensing inclinations of a roll shaft and a pitch shaft of the vehicle, a main controller(110) having an A/D converter(404) to convert inclinations sensed by the sensing elements to digital signals, a speaker(402) for generating a warning sound, a panel switch(406) for applying an operation instruction, a panel lamp(408) for informing of an operation state, and a processor(400) for outputting a dangerous inclination state with the speaker if output signals of the A/D converter deviate from a predetermined range, a power supply signal, a remote operation signal, and a speed instruction signal, and computing positions of the jacks according to encoder signals, and a servo controller(112) having a relay(450) for connecting or non-connecting power supply according to the power supply signal, and a servo control module(460) to be supplied with the power supply via the relay for operating in an enable state according to the remote operation signal to drive the jacks according to the speed instruction signal and supplying a resolver signal after converting to the encoder signal to the processor.
