A hill start assist control (HAC) method and system for vehicles is provided to prevent malfunction and sensitive operation of an HAC function, generated due to misrecognition of a flat road as a hill when the vehicle is accelerated after braking on the flat road, caused by use of a value sensed by an acceleration sensor in determination of a hill. For this purpose, a corrected gradient, in which a tilt of the vehicle in the pitch direction is reflected in a gradient acquired from the value sensed by the acceleration sensor, is used as an actual road gradient value.
