PROBLEM TO BE SOLVED: To overcome a risk such that, in a hybrid vehicle that is provided with a plurality of prime bars of an engine and an electric motor and that is designed to normally travel by driving the engine continuously and to increase the driving force, by driving the electric motor when a traveling load of a certain level or more occurs to the vehicle, the motor becomes incapable of assisting the driving force of the engine properly unless a detecting device for detecting the traveling load of the vehicle detects the load accurately. SOLUTION: In the vehicle of the structure above, an oil pressure-detecting device 27 that detects the pressure of oil is provided in a piping route 26 between a hydraulic pump 15 driven by the engine 3 and a hydraulic valve 16. This oil pressure-detecting device 27 is interlocked and associated with a transforming device 28 that supplies electric power to the oil pressure detecting device 27 and the motor 23. When the oil pressure-detecting device detects an oil pressure drop of a certain level or less, the transforming device 28 drives the motor 23 to assist the driving force of the engine 3. |
