The invention discloses a control method and a control system for the curve speed of an automatic driving vehicle in rainy days. In order to effectively prevent huge potential safety hazards caused by overspeed driving of a driver, the research purpose of the invention is to design an active speed-limiting control system which can identify the safety posture of the vehicle in real time and can actively early warn or decelerate. The system mainly has the functions of identifying a vehicle driving safety state in real time, pre-judging a driving behavior, giving an alarm signal in real time and actively implementing braking and deceleration, and the vehicle auxiliary driving active limit control system expands the sensing ability of a driver by utilizing a modern information technology and a sensing technology. When external information (such as turning radius and gradient) is transmitted to a driver, the identified vehicle condition information is comprehensively utilized, the safety degree of the current running condition of the vehicle is judged, and measures can be automatically taken to control the vehicle in an emergency, so that the vehicle actively avoids danger, and safe driving of the vehicle is ensured or the injury degree of an accident is reduced to the greatest extent.
