Abstract
An ECU executes a program including the steps of carrying out fluctuation suppression control in a case where a request to start an engine has been made, a rotation mode has been selected, and a motor is being driven and canceling fluctuation suppression control in a case where a full drive mode has been selected and engagement between a pinion gear and a ring gear has been completed.
Claims9
An engine starting device, comprising:
- a starter for start of an engine;
- equipment coupled to a crankshaft of said engine and causing load of said engine to fluctuate;
- and
- a control device for said starter,
- said starter including
- a second gear that can be engaged with a first gear coupled to said crankshaft of said engine,
- an actuator for moving said second gear to a position of engagement with said first gear in a driven state, and
- a motor for rotating said second gear,
- said control device being capable of individually drive each of said actuator and said motor,
- said control device having a rotation mode in which said motor is driven prior to drive of said actuator, and
- said control device suppressing fluctuation of the load of said engine and said equipment before said actuator is driven, while said rotation mode is being executed.
An engine starting method, an engine being provided with a starter for starting said engine, equipment coupled to a crankshaft of said engine and causing load of said engine to fluctuate, and a control device for a starter, said starter including a second gear that can be engaged with a first gear coupled to said crankshaft of said engine, an actuator for moving said second gear to a position of engagement with said first gear in a driven state, and a motor for rotating said second gear, each of said actuator and said motor being able to individually be driven, comprising the steps of:
- driving said actuator and said motor in a rotation mode in which said motor is driven prior to drive of said actuator;
- and
- suppressing fluctuation of the load of said engine and said equipment before said actuator is driven, while said rotation mode is being executed.
