Abstract
In response to an operation stop instruction of an engine, the technique of the invention carries out control to make the engine stop at a specific position that is far from a first compression stroke at a subsequent start of the engine, for example, at a target stop position θt set at a top dead center of a piston in a proximate compression stroke, which is immediately before the first compression stroke. In the first compression stroke at the subsequent start of the engine, the revolving speed of the engine stopped at the specific position is significantly higher than the revolving speed of the engine stopped at a position close to the first compression stroke. Such control thus ensures a smooth compression stroke at the subsequent start of the engine.
Claims20
A driving apparatus, comprising:
- an internal combustion engine;
- a torque output device that outputs a torque to an output shaft of said internal combustion engine;
- and
- a controller that controls said internal combustion engine to stop operations of said internal combustion engine in response to an operation stop instruction of said internal combustion engine, while controlling operations of said torque output device on the basis of a first compression stroke at a subsequent start of said internal combustion engine as a standard, in order to make said internal combustion engine stop at a target stop position that is different from the standard by a predetermined angle.
An automobile, comprising:
- an internal combustion engine;
- a torque output device that outputs a torque to an output shaft of said internal combustion engine;
- and
- a controller that controls said internal combustion engine to stop operations of said internal combustion engine in response to an operation stop instruction of said internal combustion engine, while controlling operations of said torque output device on the basis of a first compression stroke at a subsequent start of said internal combustion engine as a standard, in order to make said internal combustion engine stop at a target stop position that is different from the standard by a predetermined angle.
