Abstract
Hybrid electric vehicle includes an engine, a first electric motor, a second electric motor, an electric power storage device, and a control device. The control device is configured to control the engine and the first electric motor so that the engine is operated at a first predetermined engine speed while outputting a predetermined torque, and to control the second electric motor so that a driving force based on a required driving force is output, when the rapid catalyst warm-up is executed when the engine is idle off.
Claims11
A hybrid electric vehicle, comprising:
- an engine including an exhaust gas control device provided with a catalyst that controls exhaust gas and an in-cylinder injection valve, the exhaust gas control device being attached to an exhaust system;
- a first electric motor that is mechanically connected to an output shaft of the engine and that is configured to generate electricity;
- a second electric motor that is configured to input and output power for traveling;
- an electric power storage device that is configured to exchange electric power with the first electric motor and the second electric motor;
- and
- a control device configured to control the engine, the first electric motor, and the second electric motor,
- wherein
- the control device is configured to, while rapid catalyst warm-up, in which fuel is injected in a compression stroke or an expansion stroke in the engine and the engine is operated with an ignition timing being retarded so as to warm up a catalyst of the exhaust gas control device, is being performed during idle-off in which an idling operation of the engine is not instructed and the engine is operated,
- control the engine and the first electric motor to operate the engine at a first predetermined engine speed while the engine outputs predetermined torque, and
- control the second electric motor to output a driving force based on a required driving force for travelling.
