| 发明名称 | Method of controlling a hydraulic system | ||
| 摘要 | A method of controlling a hydraulic system having a variable displacement pump operatively coupled to an engine. The method includes detecting a speed of the engine, and determining a desired power value of the pump. The method also includes identifying an allowable power value that may be expended by the pump at the detected speed. The method also includes selecting a pump power value. The selected pump power value is the lower of the allowable power value and the desired power value. The method further includes adjusting the pump to deliver the selected pump power value. | ||

| 主权项 | 1. A method of controlling a hydraulic system having a variable displacement pump operatively coupled to an engine, comprising: detecting a speed of the engine; determining a desired power value of the pump based on user input; identifying an allowable power value that may be expended by the pump based on a map that indicates the allowable power value at the detected speed; selecting a pump power value, the selected pump power value being the lower of the allowable power value and the desired power value; and adjusting the pump to deliver the selected pump power value. | ||
