A longitudinal control method and system for an automatic driving vehicle, the method comprises: detecting the longitudinal mode that the vehicle is currently in; in a follow mode, according to the correspondence between different working conditions and different control algorithms of the pre-configured vehicle in the follow mode, matching the control algorithm corresponding to the current working condition, and controlling the automatic driving vehicle to follow the motion according to the matched control algorithm; in a cruise mode, obtaining the current vehicle speed of the present vehicle in the cruise mode, and calculating a relative speed difference between the current vehicle speed and an allowable maximum vehicle speed of the present vehicle; and correcting so that the changing amplitude of the relative speed difference during the control period is within a preset range, calculating the acceleration of the present vehicle according to the corrected relative speed difference, and adjusting the vehicle speed of the present vehicle in the cruise mode on the basis of the acceleration of the present vehicle. The longitudinal control method and system for the automatic driving vehicle improve the efficiency, security and comfort of the entire longitudinal control algorithm.
