    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: When a transmission selector lever is operated from P or N range to D range, an input clutch to be engaged at the fifth gear position is temporally engaged to reduce shift shock when the engaging element for the first gear position is engaged. An oil pressure command value for actuating the input clutch is increased with a constant inclination from a start point oil pressure value, and the start point oil pressure value is lowered when the engine speed is low or when an oil temperature is high. Even if a timing of completion of filling of working fluid to the input clutch is fluctuated, the difference between the actual oil pressure and the oil pressure command value is suppressed to a small level and the occurrence of shock due to surge at the time of the filling completion is prevented.
