Abstract
A hybrid vehicle includes an engine, a motor generator capable of controlling the revolution speed of the engine, and an ECU configured to control ignition timing of the engine. The ECU modifies, in the case where the revolution speed of the engine is not controlled by the motor generator, the ignition timing for startup of the engine to a further timing advancing side, as compared to the case where the revolution speed of the engine is controlled by the motor generator.
Claims11
A hybrid vehicle comprising:
- an engine,
- a rotating electric machine capable of controlling a revolution speed of the engine, and
- a control device configured to control ignition timing for startup of the engine, wherein
- the control device modifies the ignition timing for startup of the engine depending on whether or not the revolution speed of the engine is controlled by the rotating electric machine, and
- a case where the revolution speed of the engine is controlled by the rotating electric machine corresponds to a state where load is applied to the engine from the rotating electric machine, such that the revolution speed of the engine is maintained at a predetermined revolution speed by torque of the rotating electric machine, and a case where the revolution speed of the engine is not controlled by the rotating electric machine corresponds to a state where load is not applied to the engine from the rotating electric machine, and the revolution speed of the engine is not maintained at the predetermined revolution speed by torque of the rotating electric machine.
A hybrid vehicle comprising:
- a power storage device,
- an engine,
- a first rotating electric machine capable of controlling a revolution speed of the engine,
- a second rotating electric machine generating traction driving power using electric power from the power storage device, and
- a control device configured to control ignition timing for startup of the engine, wherein
- the control device modifies the ignition timing for startup of the engine depending on whether or not the revolution speed of the engine is controlled by the rotating electric machine, and
- a case where the revolution speed of the engine is controlled by the rotating electric machine corresponds to a state where load is applied to the engine from the rotating electric machine, such that the revolution speed of the engine is maintained at a predetermined revolution speed by torque of the rotating electric machine, and a case where the revolution speed of the engine is not controlled by the rotating electric machine corresponds to a state where load is not applied to the engine from the rotating electric machine, and the revolution speed of the engine is not maintained at the predetermined revolution speed by torque of the rotating electric machine.
A control method of a hybrid vehicle including an engine and a rotating electric machine capable of controlling a revolution speed of the engine, the control method comprising the steps of:
- determining whether or not the revolution speed of the engine is controlled by the rotating electric machine, and
- modifying ignition timing for startup of the engine according to a determination result by the determining step, and
- a case where the revolution speed of the engine is controlled by the rotating electric machine corresponds to a state where load is applied to the engine from the rotating electric machine, such that the revolution speed of the engine is maintained at a predetermined revolution speed by torque of the rotating electric machine, and a case where the revolution speed of the engine is not controlled by the rotating electric machine corresponds to a state where load is not applied to the engine from the rotating electric machine, and the revolution speed of the engine is not maintained at the predetermined revolution speed by torque of the rotating electric machine.
