The invention discloses a vehicle body leveling method based on PLC control. The vehicle body leveling method based on PLC control comprises the steps that a vehicle body leveling system based on PLC control is firstly established; a PLC controller outputs current to control a proportional valve through a pulse output plate so as to enable four leveling vehicle legs to extend out and reach the ground, reads a pressure sensor signal through an A/D plate and determines whether the vehicle legs reliably reach the ground or not according to the situation that the pressure sensor signal reaches a set pressure value; the A/D plate reads a double-shaft tilt angle sensor signal to detect the leveling accuracy of a vehicle body and adjusts the elongation of the vehicle legs according to the leveling accuracy in real time till the set leveling accuracy is reached. The vehicle body leveling method based on PLC control has the advantages of being high in leveling accuracy, short in time and capable of meeting the leveling requirements of heavy vehicle loading devices including launching vehicles, fire fighting trucks and the like.
