Abstract

An engine synchronization method may include: detecting teeth numbers of crank teeth installed on a crankshaft based on a pulse signal generated from a crankshaft position sensor; calculating a tooth period between a falling edge and a next falling edge of the pulse signal generated from the crankshaft position sensor and detecting a missing tooth based on the calculated tooth period; determining whether the detected missing tooth is an actual missing tooth based on a tooth number detected at the time of detecting the missing tooth; and performing synchronization control of an engine when it is determined that the detected missing tooth is the actual missing tooth.
