A method for compensating a flow rate at a neutral position of an operation lever of construction equipment is adapted so that when RPM of an engine becomes different, an actuator (40) can be identically driven according to an operating amount (Pi) of the operation lever (60). The method comprises the steps of: setting a first flow rate (q) related to the operation lever and a second flow rate (qn) related to the engine; evaluating whether the operation lever is at the neutral position, and controlling the hydraulic pump to discharge a minimum flow rate; when the operation lever (60) is not at the neutral position and when the second flow rate (qn) for compensating the engine rpm is more than the first flow rate (q) for the operation lever, controlling the hydraulic pump to discharge the second flow rate (qn) for compensating the engine rpm; and when the operation lever is not located at the neutral position and when the first flow rate (q) for the operation lever is more than the second flow rate (qn) for compensating the engine rpm, controlling the hydraulic pump to discharge the flow rate (q) corresponding to the operating amount (Pi) of the operation lever (60). <IMAGE> |
