摘　　要：针对全液压平地机在小油门工况下行驶和作业时"游车"的问题,在进行原因深入剖析之后,运用关联发动机转速、功率以及扭矩等系统参数的液压主泵和马达排量调节的控制策略,成功解决了机器"游车"的问题,使得机器在小油门工况下行驶和作业平稳,速度不来回波动。既节能减排、降低油耗和提高发动机的工作效率,同时也改善了机器操作的舒适性。Aiming at the problem of the speed fluctuation in small throttle condition,the reasons are analyzed . The control strategy is proposed based on associating hydraulic pump and hydraulic motor output volume with engine speed,torque, power and other system parameters,the problem of speed fluctuation is solved successfully,the machine traveland operation becomes steady under small throttle condition. Energy conservation,reduction,work efficiency improvement,comfortable operation, are realized.
