Abstract
When a vehicle is in a traveling state having a low necessity to quickly increase required traveling torque, high-rotational-speed engine starting unit that reduces an emission amount of particulate matter emitted during engine starting starts the engine. Since quick torque response is not required when the vehicle is in the traveling state having the low necessity to quickly increase the required traveling torque, the high-rotational-speed engine starting unit starts the engine, so that increase of the emission amount of particulate matter emitted during engine starting can be curbed.
Claims8
A control system of a hybrid vehicle that has an engine and a motor as driving force sources, and is configured to be able to stop and start the engine during traveling, comprising
- a plurality of engine starting units that starts the engine, the engine starting units including a first engine starting unit that curbs increase of an emission amount of particulate matter emitted during starting of the engine,
- wherein the first engine starting unit starts the engine, when the hybrid vehicle is in a traveling state having a low necessity to quickly increase traveling torque of the hybrid vehicle.
