工程机械先导手柄与发动机转速的自动协同控制

Automatic Collaborative Control of Pilot Handle and Engine Speed of Engineering Machinery

针对目前工程机械的先导手柄与发动机转速的控制弊端,分析研究了发动机转速半自动控制与发动机转速自动控制,运用先导手柄直接控制发动机转速变化的控制系统,不仅减少了脚踏油门的控制、降低操作强度以及减少发动机空载时的燃油损耗,还优化了手柄位移与发动机转速间的控制关系。发动机转速随手柄位移变化,降低发动机转速阶跃变化对系统的冲击,使控制过程更流畅。并在协同控制实现方法及注意事项等方面进行了系统性分析。

According to the control shortcomings of the pilot handle and engine speed of engineering machinery,the semi-automatic control and automatic control of engine speed were analyzed and studied.The pilot handle was used to directly control the change of engine speed.The control system not only reduces the control of pedal accelerator,reduces operating strength,reduces the fuel loss of engine,and optimizes the control relationship between the handle displacement and engine speed.The engine speed changes with the handle displacement,which reduces the impact of the engine speed step change on the system and makes the control process more smooth.And the realization method and attention of collaborative control were systematically analyzed.
