Title:
AUTOMOBILE
Document Type and Number:
Japanese Patent JP2005105950
Kind Code:
A
Abstract:

To suppress exhaust emission from an internal combustion engine and suppress the occurrence of catalyst odor from a catalyst in an inert state by suppressing load on the internal combustion engine immediately after starting.

In a hybrid automobile having an engine and a motor connected to the engine, when the residual capacity of a battery becomes less and charging to a battery is requested when the automobile is stopped with a shift position at a P range, the charging to the battery is retained and the warmup operation of the engine is continued until a load operation prohibiting time tref set as a time shorter as a cooling water temperature Tw in engine starting is higher is passed (S140). After the load operation prohibiting time tref is passed, a power from the engine is regenerated by the motor and the charging to the battery is started (S150). By this, load on the engine during the warmup operation can be suppressed to suppress the exhaust emission and suppress the occurrence of catalyst odor from the catalyst in the inert state.
