摘要： When the shift position is changed to the drive position, the amount of oil that is supplied to an automatic shift unit is increased by a larger amount as the standby hydraulic pressure is lower. Therefore, even if the standby hydraulic pressure is decreased, the required hydraulic pressure is more easily achieved when the shift position is changed to the drive position. Therefore, it is possible to decrease the standby hydraulic pressure without slowing down the response to the automatic shift unit to the hydraulic pressure and reducing the useful life of the automatic shift unit. Thus, the amount of electricity consumed by the electric oil pump is reduced. As a result, it is possible to enhance the fuel efficiency.

摘要翻译： 当换档位置改变为驱动位置时，供给到自动换档单元的油量随着备用液压压力的降低而增加较大的量。 因此，即使在备用液压降低的情况下，当换挡位置变为驱动位置时，也能够更容易地实现所需的液压。 因此，可以在不使对自动换档单元对液压的响应减慢的同时降低备用液压并且降低自动换档单元的使用寿命。 因此，电动油泵消耗的电量减少。 结果，能够提高燃料效率。

摘要： A first reduction section of a hybrid power unit reduces an output of a motor when a transmission is shifted. A charge determining section determines whether charging of a battery is permitted. If the charge determining section determines that charging of the battery is not permitted in a period where the first reduction section reduces the output of the motor, a second reduction section reduces a power generation amount of a generator. Therefore, a shift shock is reliably prevented without generating response delay in an output rotation in the hybrid power unit.

摘要： A control system of a vehicular drive system is provided with a controller that reduces regeneration torque of a second motor when an automatic transmission that is shifted down during coasting is in an inertia phase. By reducing the regenerating torque of the second motor during the inertia phase, the amount of work required for producing regeneration torque of the second motor is reduced, and the rotational speed of a power transmitting member coupled to a differential unit can be easily raised, whereby shift shock at the time of shifting is favorably reduced.

摘要： A control device for hybrid vehicle is provided with property alter means 88 that is operative based on whether or not an EV running mode is set and alters a given property used for determining demanded output torque TOUTt of a transmission mechanism 10 by referring to an accelerator opening Acc. This suppresses occurrence of engine startup to meet a requirement for the EV running mode to be initiated. The property alter means 88 alters the given property such that during an EV running mode turn-on state, demanded output torque TOUTt determined based on the accelerator opening Acc has a lower value than that set for an EV running mode turn-off state. That is, this causes a drop in sensitivity of demanded output torque TOUTt determined based on the accelerator opening Acc. Thus, the occurrence of engine startup induced upon depressive operation of an accelerator pedal during the EV running mode is suppressed.
