Abstract
Disclosed is to a method for compensating noise of a crank sensor in a vehicle. When noise is applied to a crank sensor, information of a crank is predicted based on information input up to now without canceling engine synchronization. The method for compensating noise of a crank sensor includes: judging an engine stroke based on an ignition angle and, based on amount of compensation determined accordingly, creating virtual information of a crank, when judgment of fault of crank signal occurs discontinuously.
