Abstract: PROBLEM TO BE SOLVED: To enhance the drive feeling by a drive by changing the output characteristic from a drive power apparatus. SOLUTION: Torque maps, indicating relations between output from an engine 30 and output from a motor are stored in a plurality of ROMs 64, the torque map is selected based on the operation of a mode selection switch 74 by a driver, and the output from the engine 30 and an output from the motor 40 are set based on the selected torque map, pedal depression on the accelerator pedal and the number of rotations of drive shaft 54 in order to control the engine 30 and motor 40. When a dashboard which switch 76 is turned on, the motor 40 is driven with an output which exceeds the rated output only within a short-period of time to provide an output exceeding the output that is preset with the selected torque map. The drive feeling by a driver can be improved by selecting the desired torque map and operating the dashboard switch 76.

Abstract: PROBLEM TO BE SOLVED: To surely decide engine start, without impairing accelerating performance, even if it is mounted in a so-called hybrid car equipped with a single motor and a single engine. SOLUTION: A start deciding device is applied to a drive device in which a motor 34 directly coupled with an engine 32 is formed so as to start the engine 32, where the driving force of the motor 34 is changed in the decremental direction, after the fuel supply to the engine 32 and ignition therein are commenced. If the engine revolving speed rises regardless of this change, decision is made that the engine 32 has attained the completely combusted condition.
