摘　　要：自行式液压平板车是大型工程设备运输的关键设备,运输对象以超高、超宽、超重为重要特征,其运输过程需保证运行的安全性。针对自行式液压平板车工作中出现的虚腿情况,提出了一种四点支撑的液压平台调平方法,即"面追逐式"误差控制法,并对自动调平过程中控制逻辑进行了设计。实车试验表明,该方法可以有效预防平板车自动调平过程中虚腿的产生,提高了车辆运行的安全性。Self-propelled hydraulic transporter is the key device of large-scale equipment. As the feature of the equipment is high, wide and overweight, it is important to ensure their safety during transport operation. A new method of four-point support called ＂flat chasing style ＂ leveling strategy was proposed according to the weak leg of self-propelled hydraulic transporter. The control logic of the automatic leveling process was designed. The test on the self-propelled hydraulic transporter shows that this method can prevent the situ- ation of weak leg effectively and progress the speed and safety of automatic leveling process.
