Abstract: An output shaft is arranged to be lateral and parallel to engine input shafts and a motor input shaft. An engine side gear mechanism for transmitting a power of the engine input shafts to the output shaft is provided. A motor side gear mechanism for transmitting a power of the motor input shaft to the output shaft is provided. An input side clutch engages and disengages the engine input shafts and the motor input shaft. When the input side clutch is engaged, the power transmission between a position where the engine side gear mechanism is arranged on the engine input shafts and a position where the motor side gear mechanism is arranged on the motor input shaft is invariably possible.

Abstract: Power generated by an engine is inputted to a carrier of a first planetary gear mechanism. Power generated by a motor is inputted to a sun gear of a second planetary gear mechanism. Power from a ring gear of the first planetary gear mechanism and power from a carrier of the second planetary gear mechanism are combined and transmitted to an axle of driving wheels. While power input from the engine to the carrier of the first planetary gear mechanism is maintained, rotation of a sun gear of the first planetary gear mechanism is restricted with a first clutch, a second clutch or a first brake. While power input from the motor to the sun gear of the second planetary gear mechanism is maintained, rotation of a ring gear of the second planetary gear mechanism is restricted with a second brake or a third clutch.

Abstract: When an arriving electric vehicle arrives at a car park with parking spaces, a parking state detection means in a parking and power charging system detects the presence of empty parking spaces. An assignment means assigns a ranking of charging performance to each detected empty parking space so that the empty parking space having the charging device of a higher charging performance has a higher ranking of charging performance on the basis of descending order of charging performance of the charging devices. A communication means obtains vehicle parameters of the arriving electric vehicle. A parking space instruction means instructs the arriving electric vehicle to move to and be parked in the empty parking space having the ranking of charging performance selected on the basis of the vehicle parameter such as necessity to charge or degree to easily charge the on-vehicle battery mounted on the arriving electric vehicle.
