The invention discloses a voice broadcast auxiliary driving method for real-time traffic signal lamp detection and recognition. The method comprises the following steps: acquiring real-time video information in front of a vehicle; the real-time video information is preprocessed; traffic signal lamp detection is carried out; traffic signal lamp identification is carried out by combining a preprocessing result; identifying the signal state of the traffic signal lamp; the recognition result of the signal state recognition is sent to the voice broadcast module; and broadcasting the identification result in real time. Real-time video information is obtained through the camera in the vehicle, the area image is obtained through preprocessing, whether traffic signal lamp detection is carried out or not is judged by associating the area image with the navigation map, and when traffic signal lamp detection needs to be carried out, the preprocessed area image is used for carrying out traffic signal lamp state recognition. Whether traffic signal lamp detection needs to be carried out or not can be judged in advance, the recognition speed is improved through a regional image mode, and efficient driving process auxiliary driving can be carried out.
