APPARATUS AND METHOD FOR STARTING ENGINE OF MILD HYBRID ELECTRIC VEHICLE
First Claim
1. An apparatus for starting an engine of a mild hybrid electric vehicle, the apparatus comprising:
- an ignition switch including a plurality of contact points;
a mild hybrid starter &
generator (MHSG) including a stator and a rotor internally disposed within the stator, and configured to start the engine or generate electricity according to an output of the engine;
a MHSG wheel rotating integrally with the rotor, and having at least three teeth on a circumference thereof;
a MHSG position detector detecting positions of the teeth; and
a controller configured to determine a top dead center (TDC) of a predetermined cylinder according to a signal of the MHSG position detector, and to rotate the MHSG to start the engine.
