Abstract
A power outputting apparatus is provided with an engine, a clutch motor connected to a crank shaft thereof, and an assist motor connected to the crank shaft or a drive shaft by a switch apparatus. At a time of moving a vehicle backward, an operation characteristic of the engine is set to a characteristic on a low torque side in place of a characteristic at a time of moving forward (a characteristic giving priority to an efficiency). In addition, a torque Tm larger than an engine torque Te and in a reverse direction is output from the assist motor. As a result, a high torque is output to the drive shaft while an electric power is regenerated by the clutch motor, whereby the vehicle can be backward moved.
