Excavator traveling high-low speed switching control method and system
The invention further discloses an excavator traveling high-low speed switching control method. The excavator traveling high-low speed switching control method comprises the following steps that S1, the traveling speed of an excavator is detected and compared with the speed reference section; S2, load pressure of a traveling motor of the excavator is detected, and the load pressure is compared with the pressure reference section; S3, driving state information of the traveling motor is detected; and S4, when the traveling motor is in a driving state, the traveling speed of the excavator is located in the low-speed reference section, and the load pressure of the traveling motor is located in the low-pressure reference section, the driving mode of the traveling motor is controlled to be a high-speed driving mode; when the traveling motor is in a driving state, the traveling speed of the excavator is located in the high-speed reference section, and the load pressure of the traveling motor is located in the high-pressure reference section, the driving mode of the traveling motor is controlled to be a low-speed driving mode; and otherwise, the current driving mode of the traveling motor is kept unchanged. According to the excavator traveling high-low speed switching control method, the switching is convenient, stable and reliable. The invention further discloses an excavator traveling high-low speed switching system.
本发明还公开了一种挖掘机行走高低速切换控制方法，包括如下步骤：S1、检测挖掘机的行走速度，并与速度基准区段比较；S2、检测挖掘机行走马达的负载压力，并与压力基准区段比较；S3、检测行走马达的驱动状态信息；S4、当行走马达处于驱动状态、挖掘机的行走速度位于低速基准区段内且行走马达的负载压力位于低压基准区段内时，将行走马达的驱动模式控制为高速驱动模式；当行走马达处于驱动状态、挖掘机的行走速度位于高速基准区段内且行走马达的负载压力位于高压基准区段内时，将行走马达的驱动模式控制为低速驱动模式；否则，保持行走马达的当前驱动模式不变。切换方便、平稳，可靠。本发明还公开了一种挖掘机行走高低速切换系统。
