    摘要： When an engine is driven on a different type of fuel (for example, ethanol-containing fuel) from a reference fuel (for example, gasoline) and the engine torque is thus greater than that produced when the engine is driven on the reference fuel, a differential state control device expands a non-differential range compared to that at the time when the reference fuel is used. Thus, in the case where a plurality of types of fuel including the reference fuel are supplied to the engine, the advantage of switching a power distribution mechanism between a differential enabled state and a non-differential state can be fully utilized in correspondence with engine torque characteristics which may vary in accordance with the type of fuel for the engine. As a result, the fuel consumption rate can be reduced in correspondence with the plurality of types of fuel supplied to the engine, for example.

    摘要翻译： 当发动机从参考燃料（例如汽油）在不同类型的燃料（例如含乙醇的燃料）上被驱动时，发动机转矩大于在发动机对参考燃料的驱动时产生的转矩， 差分状态控制装置与使用参考燃料时相比扩展非差动范围。 因此，在将包含基准燃料的多种燃料供给到发动机的情况下，能够根据发动机转矩充分利用在差动启动状态与非差动状态之间切换配电机构的优点 可根据发动机的燃料类型而变化的特性。 结果，能够例如与供给发动机的多种燃料相对应地减少燃料消耗率。

    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 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 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.
