Provided is an automatic drive control method for a vehicle in which, as a target control quantity for automatically controlling a rudder angle of front wheels, a target control quantities Δθptj of a pinion angle for the current cycle to the c-th cycle are calculated by prediction according to parameters for trajectory control based on a driving situation of the vehicle; and when a magnitude of a target control quantity Δθpt1 for the current cycle is less than a preliminarily set reference value P and it is determined that the probability is high that the target control quantity Δθptj has a sign identical to a sign for the current cycle and the magnitude thereof increases to the reference value P or above by the c-th cycle at the latest, the magnitude of the target control quantity Δθpt1 for the current cycle is increasingly corrected to the reference value P.
