Zusammenfassung:The invention discloses a method and a device for determining a risk level of a lane changing behavior of an intelligent vehicle. The method comprises: comprehensively evaluating the risk level of the lane changing behavior of an intelligent vehicle from a safety index, an efficiency index and a comfort index; calculating the lane changing behavior risk comprehensive evaluation indexes of vehicles in a target vehicle communication range before and after lane changing of the target vehicle through lane changing microscopic information; and according to historical data percentage division of the vehicle lane changing behavior risk comprehensive evaluation indexes, determining risk levels corresponding to the current comprehensive evaluation indexes in the two databases so as to determine the current lane changing behavior risk level of the target vehicle. According to the invention, the interaction between the lane changing vehicle and all vehicles in the passing range is comprehensively considered, the lane ch
