The present invention relates to a method and an apparatus for determining a drowsy state of a vehicle driver. According to an embodiment of the present invention, the method for determining the drowsy state of the vehicle driver, which is conducted by the apparatus for determining the drowsy state of the vehicle driver, comprises the following steps of: calculating a normal drowsy index, which is a reference for determining a drowsy state, when the vehicle is normally driving, by learning driving patterns of the driver in a longitudinal direction and a transverse direction; collecting the driving patterns of the driver in a longitudinal direction and a transverse direction, when the vehicle is currently driving, to calculate a current drowsy index, which shows drowsy characteristics of the current driver, to analyze the current drowsy index calculated based on the calculated normal drowsy index, and to determine the drowsy state of the driver; and generating a drowsy driving warning to the driver when the driving pattern of the driver is determined as a drowsy driving. The present invention aims to provide a method and apparatus for determining the drowsy state of a vehicle driver, which are able to determine drowsy driving without an additional machine apparatus, and generate a warning.
