PROBLEM TO BE SOLVED: To prevent the stopping of the operation of a prime mover when a drive shaft is suddely stopped during the time when control for obtaining the locked sate of the output shaft and the drive shaft of the prime mover and the control for making the difference of the number of revolutions constant are performed. SOLUTION: In a power transmission apparatus 20, which is linked to a crank shaft 56 of an engine 50, a clutch motor 20 and an assist motor 40 are provided and controlled with a controller 80. The controller 80 controls the operation for obtaining the electromagnetic locked state of an outer rotor 32 and an inner rotor 34 of the clutch motor 30, detects the state that a drive shaft 22 is suddenly stopped by quick braking and the like during the control for making the difference in number of revolutions constant based on the OFF state of accelerator pedal 64 and the number of revolutions of the engine 50, zeroes the torque of the clutch motor 30 and removes the load of the engine 50. As a result, the stopping of the operation and the reverse rotation of the engine 50 can be prevented. |
