Road roller control system and method and road roller
The invention provides a road roller control system which can provide various working modes including an economic mode and an efficient mode, and according to the selected working mode, an engine controller and a hydraulic controller respectively control the operation rotating speed of an engine and the motor displacement of a hydraulic system. Wherein the engine rotating speed in the economic mode is lower than the engine rotating speed in the efficient mode, the motor displacement in the economic mode is lower than the motor displacement in the efficient mode, and the ratio of the motor displacement of the hydraulic system to the running rotating speed of the engine is constant. Thus, according to the working requirements of the road roller, the working mode meeting the requirements can be selected, and when the required load is low, the low engine rotating speed and the low motor displacement are selected, so that resource waste is avoided, and the working cost of the road roller is reduced.
本申请提供了一种压路机控制系统，该系统能够提供包括经济模式和高效模式的多种工作模式，根据所选择的工作模式，发动机控制器和液压控制器分别控制发动机的运行转速以及液压系统的马达排量，其中经济模式中发动机转速低于高效模式中的发动机转速，经济模式中的马达排量低于高效模式中的马达排量，液压系统的马达排量与发动机的运行转速的比值恒定。如此，能够根据压路机的工作需求，选择符合需求的工作模式，当所需负荷较低时，选择较低的发动机转速和较低的马达排量，从而避免资源浪费，减少压路机的工作成本。
