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: A fuel cell system includes: an AC impedance measuring unit which measures an AC impedance of a fuel cell at a scavenging start and which measures an AC impedance of the fuel cell when a predetermined time has elapsed from the scavenging start; a scavenging execution time estimation unit which estimates a scavenging execution time based on the AC impedance measured at the scavenging start, the AC impedance measured at a time when the predetermined time has elapsed from the scavenging start, and the predetermined time; and an error processing unit which forcibly terminates scavenging processing if no AC impedance can be measured at the time when the predetermined time has elapsed from the scavenging start.

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.

Abstract: Provided is a fuel cell system which can accurately detect the water state of a fuel cell to appropriately control the water content of the fuel cell. Based on an FC outlet temperature detected by a temperature sensor, an FC outlet temperature change speed detection unit detects an FC outlet temperature change speed for a unit time. If the FC outlet temperature change speed detection unit judges that the detected FC outlet temperature change speed is lower than a change speed reference value stored in a memory, an impedance measurement instruction is transmitted to an impedance calculation unit. On receiving the impedance measurement instruction from the FC outlet temperature change speed detection unit, the impedance calculation unit performs the impedance measurement for the second time. In consequence, it is possible to realize such scavenging control as to keep the water content of a fuel cell at an appropriate level by the minimum number of impedance measurement times (e.g., twice).

The impedance comparator compares a measured impedance value supplied from an impedance operation unit with the impedance reference value and performs scavenging control based on the comparison result.
