<P>PROBLEM TO BE SOLVED: To provide a control method for construction machinery capable of increasing to be power supplied to a hydraulic-pressure generation machine in response to increase of a hydraulic-pressure load while maintaining a suitable operation condition of an internal combustion engine even at rapid increase of the hydraulic-pressure load. <P>SOLUTION: In the control method for construction machinery for operating by driving the hydraulic-pressure generator 12 with the internal combustion engine 10, an increase rate of output of the internal combustion engine 10 is set to a designated value. An output upper limit value of the internal combustion engine 10 calculated from the designated value of the increase rate and required power calculated from hydraulic-pressure output requested from the hydraulic-pressure generator 12 are compared. When a requested power exceeds the output upper limit value, the output of the internal combustion engine 10 is restrained to be the output upper limit value or below. <P>COPYRIGHT: (C)2009,JPO&INPIT |
