ABSTRACT:
A method for controlling a hydraulic pump driven by an engine, including measuring a temperature of at least one of the engine and a hydraulic fluid, comparing the measured temperature with a first predetermined temperature to judge as to whether the measured temperature is higher than the first predetermined temperature or not, comparing the measured temperature with a second predetermined temperature to calculate a difference between the measured temperature and the second predetermined temperature, and decreasing an output flow rate of the hydraulic pump by a degree according to the difference between the measured temperature and the second predetermined temperature, when the measured temperature is judged to be higher than the first predetermined temperature.
