Safety air bag detonation control method and device based on multi-information fusion and terminal

The invention discloses a safety air bag detonation control method and device based on multi-information fusion and a vehicle-mounted intelligent network connection terminal, and the method comprises the steps: obtaining camera information and radar information of a vehicle before collision, and calculating ADAS pre-collision information; wherein the ADAS pre-collision information comprises the remaining time of the predicted collision occurrence of the vehicle and the relative speed of the predicted collision at zero moment; according to the ADAS pre-collision information, judging the danger level of an impending collision; wherein the collision danger levels comprise first-level collision danger, second-level collision danger, third-level collision danger and fourth-level collision danger; acquiring and processing acceleration information of the vehicle after collision; and when it is predicted that the danger level of the impending collision is second-level, third-level or fourth-level collision danger and
