<P>PROBLEM TO BE SOLVED: To provide an equipment-mounted working vehicle with a constitution eliminating the need to increase an output of an engine even if trying to increase operating forces or operation speeds of hydraulic working machines, for reducing the generation of noise or exhaust gas. <P>SOLUTION: A traveling body 10 with the hydraulic working machines (a boom 30, an earth auger device 40 or the like) is a hybrid vehicle capable of traveling by a power source HV comprising the engine EG and an electric motor M for applying an assist output to the output of the engine EG, and a hydraulic pump P for supplying pressure oil to the hydraulic working machines is driven by the motor source HV. When an output target value of the power source HV is set according to loads of the hydraulic working machines or the like at the time of driving the hydraulic pump P by the power source HV, the assist output of the electric motor M required for making the output of the power source HV correspond to the output target value is calculated while the output of the engine EG is kept at a prescribed output (a fixed output), and the electric motor M is operated and controlled so that the calculated assist output is applied to the output of the engine EG. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
