<P>PROBLEM TO BE SOLVED: To make a configuration of a hybrid system equipped with a motor generator so as to function as generating equipment and also function as electric equipment, and automatically switchable between an operating form to perform power generation and an operating form to perform engine assistance. <P>SOLUTION: The motor generator 40 is operated as electric equipment at start time of an engine 2. Start of the engine is completed when revolving speed of the engine and revolving speed of the motor generator which operates as the electric equipment reaches predetermined revolution speeds respectively, and when change per time rate of the revolution speed of the engine exceeds given values from the start to the completion of the engine. When operating speed from a neutral position of an operating tool exceeds a predetermined rate before the lapse of predetermined time after the completion of start of the engine, the motor generator is operated as electric equipment, and when the predetermined time is lapsed without the operating speed exceeding the predetermined speed, the motor generator is operated as the generating equipment. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
