Abstract
An engine starting apparatus has a reverse-rotation detection sensor for detecting the reverse rotation of an engine. A control apparatus for controlling the engine starting apparatus performs such control that a starter motor is not rotated while the reverse rotation of the engine is detected by the reverse-rotation detection sensor, even if receiving a predetermined engine start command.
Claims9
An engine starting apparatus comprising:
- a motor for transmitting a torque to an engine of a vehicle to rotate the engine;
- and
- a motor controlling device for prohibiting rotation of said motor if the engine runs in reverse rotation.
An engine starting method used for an engine starting apparatus comprising:
- a motor for transmitting a torque to an engine of a vehicle to rotate the engine;
- and a motor controlling device for prohibiting rotation of said motor if the engine runs in reverse rotation, said motor controlling device controlling, in accordance with a start command, said motor to start the engine which is stopped while the vehicles stops,
- said engine starting method comprising:
- a first process of receiving the start command;
- a second process of judging whether or not the engine runs in the reverse rotation if the start command is received;
- and
- a third process of controlling said motor to start the engine if it is judged in said second process that the engine does not run in the reverse rotation.
