The invention discloses an automobile active safety early warning system and method based on human-vehicle-road multi-information fusion. The system comprises an information sensing module, a state monitoring module, a threshold value adjusting module, a safety early warning module and an active control module which are communicated with one another. Firstly, vehicle state information is obtained in real time through an information sensing module, the obtained vehicle state information is monitored in real time through a state monitoring module, and all state index values are calculated and processed according to the obtained vehicle state information; the threshold value adjusting module determines the safety threshold value of each state index based on a fuzzy control model according to the current lane type and driver characteristics; the safety early warning module determines an early warning level and a corresponding early warning mode according to each state index and a safety threshold thereof; and the active control module intervenes in active front wheel steering control after triggering the primary safety early warning. According to the method, the overall driving safety is improved by fusing the multi-source information, the accident rate is reduced, and the method has remarkable significance in improving the road traffic safety.
