Control device of hybrid vehicle |
摘要 |
It is provided a control device of a hybrid vehicle having a clutch in a power transmission path between an engine and a motor generator, the clutch controlling power transmission through the power transmission path depending on an engagement state, the hybrid vehicle interrupting the power transmission through the power transmission path by releasing the clutch during EV running while only the motor generator is used as a drive source for running, during the EV running while a release instruction for the clutch is output, if the engine being driven, a rotation speed of the engine is maintained within a predetermined rotation speed difference from a rotation speed of the motor generator. |

1. A control device of a hybrid vehicle having a clutch in a power transmission path between an engine and a motor generator, the clutch controlling power transmission through the power transmission path depending on an engagement state, the hybrid vehicle interrupting the power transmission through the power transmission path by releasing the clutch during EV running while only the motor generator is used as a drive source for running,
the engine being driven, such that a rotation speed of the engine is maintained within a predetermined rotation speed difference from a rotation speed of the motor generator during the EV running while a release instruction for the clutch is output, and wherein during the EV running, it is determined whether warm-up of a catalytic converter is needed, and the engine is driven when it is determined that the warm-up of the catalytic converter is needed. |
