A use index IDX indicative of a degree of use of external charging is calculated and transmitted to a vehicle external system. The vehicle external system provides a service or imposes a penalty based on the use index IDX. In a case where the degree of use of external charging is determined to be low based on the use index IDX, if the vehicle external system provides a non-preferential service or imposes a heavy penalty as compared with a case where the degree of use of external charging is determined to be high, a driver or an owner of a vehicle takes an action by which the use index is determined to indicate, a high degree of use of external charging. As a result, the use of external charging can be promoted.

A synchronous electric machine includes a stator having a plurality of teeth with first and second active surfaces; first and second stator windings having respective series of first and second coils wound on said teeth; first and second rotors having respective series of first and second permanent magnets with alternate polarities and facing said respective first and second active surfaces; wherein the first coils and the second coils of each stator winding are arranged in pairs, with two coils of each pair offset from each other by a predetermined angle; and wherein, during operation as a motor, two first coils of each pair produce concordant torque contributions on the first rotor and discordant torque contributions on the second rotor and two second coils of each pair produce concordant torque contributions on the second rotor and discordant torque contributions on the first rotor.

A hybrid power module efficiently delivers both hydraulic power and electric power. The hybrid power module may regenerate and store energy for later use. The module includes and engine and an electric motor for driving a hydraulic pump. The electric motor is operable as a starter motor for the engine and as an assist motor cooperating with the engine to power the hydraulic pump to improve dynamic response of the hydraulic pump. The module also includes an electric power source which may have an energy storage unit, and the electric motor may be operated as an electric generator providing electric energy to the energy storage unit.

A startup control device includes a vehicle temperature sensor configured to sense a temperature of the vehicle, a vehicle startup controller configured to select the second vehicle startup mode in a low temperature state in which the temperature of the vehicle is equal to or smaller than at least a first temperature judgment value when the request of the startup of the vehicle is sensed, and to select the third vehicle startup mode in an extremely low temperature state in which the temperature of the vehicle is equal to or smaller than a second vehicle temperature judgment value which is smaller than the first temperature judgment value when the request of the startup of the vehicle is sensed.

A hybrid-power driving system (HPDS) (100, 200) includes an engine, a motor, and a transmission. The HPDS may include a single clutch and the transmission can provide at least five forward speed ratios and can provide for at least one reverse speed ratio. The transmission can include three synchronizers and multiple gearwheels that are used in multiple speed ratios. In addition to a pure engine driving mode and a pure motor driving mode, the HPDS can operate using a hybrid-power driving mode (HDM). In the HDM, the HPDS can provide for shifting of gears without power interruption to the output shaft or half-axles and wheels of a vehicle. In the HDM, the continuous power being output can be achieved by keeping a synchronizer engaged with a gearwheel for two consecutive speed ratios.

A transmission for a hybrid vehicle includes a planetary gear set including at least three rotary members of which one is connected to an engine. A first anti-rotator selectively restricts rotation of the rotary member connected to the engine. A first motor generator is connected to another one of the rotary members of the planetary gear set. A second motor generator is connected to the remaining one of the rotary members of the planetary gear set. An output shaft has a first output gear thereon, which is externally engaged with the rotary member connected to the first motor generator. A second anti-rotator selectively restricts rotation of the rotary member connected to the second motor generator.

A power module assembly includes opposing end caps collectively having coolant ports and a row of cards that each have a major side defining a projection extending across the card. A side panel extends between the end caps such that the panel and row define a channel in fluid communication with the ports and configured to convey coolant directly across the cards. The side panel defines a groove that receives the projections.

A method according to an exemplary aspect of the present disclosure includes, among other things, selectively powering a heating device to augment heating of an engine oil associated with an engine of a vehicle in a manner that influences an oil quality value of the engine oil.

A planetary gear mechanism has a sun gear disposed to a rotating shaft, a plurality of pinion gears, a carrier supporting the plurality of the pinion gears, a ring gear meshing with the pinion gear on the outer diameter side of the carrier and a case holding the ring gear on the outer diameter side thereof. The ring gear is slidable in the axial direction of the rotating shaft with respect to the case. The planetary gear mechanism has a load transmission member abutting to an inner diameter side end portion of the ring gear and holding the carrier and the ring gear so as to be relatively rotatable. The load transmission member transmits an axial load from the ring gear to the carrier.

Provided a transmission including a first shaft, a second shaft connected thereto via a shift gear mechanism provided to a first shaft and generating a rotary output corresponding to a selected shift gear, a planetary gear mechanism, a transmission case for housing the planetary gear mechanism and a mounting member for fixing a ring gear of the planetary gear mechanism to the case. To the mounting member, an abutment support portion is formed for supporting the case by abutting to an inter-shaft portion positioned between the first shaft and the second shaft in the case.
