METHOD FOR CONTROLLING A HYDRAULIC PUMP OF A WHEEL LOADER
The present invention relates to a method for controlling a hydraulic pump of a wheel loader, and to this end, the present invention provides a method for controlling a hydraulic pump, capable of improving acceleration performance of the wheel loader by reducing a flow rate of the hydraulic pump when there is a request for improving the acceleration performance of the wheel loader in a situation in which an increase in injection amount of fuel is not allowed due to limits on fume production during a travel-combined acceleration of the wheel loader, and further, provides a method for sequentially controlling a pump flow rate which is a sequential control performed by firstly reducing a flow rate of a fan pump that is not directly related to the working machine, and then secondly reducing the flow rate of the pump of the working system which drives a working machine as necessary, thereby improving the acceleration performance of the wheel loader by reducing torque of the working system while minimally influencing working performance when the engine reaches a rating limit in a transition state.
