The embodiment of the invention relates to the technical field of intelligent driving, and particularly discloses an alarm and control method for danger when a vehicle goes out of a high-speed ramp. According to the embodiment of the invention, road section detection and surrounding traffic participation detection are carried out; when the vehicle is in a high-speed ramp leaving state and there is no traffic participant on an adjacent lane, calculating a first required acceleration a1, and comparing the first required acceleration a1 with the acceleration a0 of the vehicle at a0lt; if a1, danger alarm or danger control processing is carried out; when the vehicle is in a high-speed ramp leaving state and traffic participants exist in adjacent lanes, calculating a second required acceleration a2, and comparing the second required acceleration a2 with the acceleration a0 of the vehicle at a0lt; and a2, carrying out danger alarm or danger control processing. The system can give an instructive alarm to a driver, or control the vehicle when the driver is allowed, can avoid traffic accidents caused by driving out of the ramp, guarantees the safety of the body and property of the driver, and improves the driving feeling.
