ABSTRACT:
Disclosed is an engine starting apparatus which suppresses engine vibrations and noises during engine cranking and reduces consumption of electric power supplied for engine cranking. When an engine starts to rotate to produce its torque, electric power supplied to a starter motor for engine cranking is reduced gradually so that a sum of torques produced by the starter motor and the engine may be prevented from increasing excessively. In the case a generator/motor is used for engine starting, operation of the generator/motor is switched from motor operation to generator operation for suppressing excessive speed rise when engine starting is completed.
