The invention relates to a speed synchronization control method of a road roller, which comprises the following steps of: based on vehicle parameters of the road roller, establishing a relation between a displacement value of a front-drive driving pump and a displacement value of a rear-drive driving pump as a dependent variable and an independent variable; by controlling the displacement value of the front-drive running pump and the displacement value of the rear-drive running pump, the front-drive running pump and the rear-drive running pump are controlled to synchronously control the rotating speed of the front-drive motor and the rotating speed of the rear-drive motor; and according to the rotating speed of the front-drive motor and the rotating speed of the rear-drive motor, a road rolling wheel and a driving wheel reach the consistent target speed. The invention further discloses a control system for realizing the control method and the road roller with the driving system. Through the relation between the independent variable and the dependent variable, the displacement values of the front-drive traveling pump and the rear-drive traveling pump change along with the independent variable, so that the traveling speeds of the road rolling wheels and the traveling wheels can be accurately synchronized.

    本发明涉及一种压路机的速度同步控制方法,包括:基于压路机的车辆参数,建立前驱行驶泵的排量值和后驱行驶泵的排量值为因变量和自变量的关系;通过控制前驱行驶泵的排量值和后驱行驶泵的排量值,控制前驱行驶泵和后驱行驶泵同步控制前驱马达的转速和后驱马达的转速;根据所述前驱马达的转速和所述后驱马达的转速,令压路轮和行驶轮达到一致的目标速度。还包括实现控制方法的控制系统和具有该行驶系统的压路机。通过自变量和因变量的关系,使得前驱行驶泵和后驱行驶泵的排量值跟随变化,使得压路轮和行驶轮的行驶速度能够精准同步。
