Suspension leveling control method and suspension leveling control device

The invention discloses a control method for suspension leveling and a suspension leveling control device. The suspension leveling control device communicates with a plurality of displacement sensors, the displacement sensors are arranged on a plurality of suspension oil cylinders respectively, and each suspension oil cylinder controls one suspension. The control method comprises the following steps: acquiring calibration ranges and set heights of a plurality of suspensions; judging whether the set height is within the calibration range or not; under the condition that the set height is within the calibration range, the actual height of each suspension is determined according to the displacement information, sent by the multiple displacement sensors, of the multiple suspension oil cylinders; and each suspension is leveled according to the comparison result of the actual height of each suspension and the set height. The all-terrain crane can be effectively prevented from tipping over, and the cross-country pas
