Intelligent lane change assisting system and method based on information fusion

The invention provides an intelligent lane change assisting system and method based on information fusion. Two 24 GHz millimeter-wave radar devices installed on the left side and the right side of the tail end of a vehicle are mainly used for detecting information of target vehicles behind the vehicle in real time. When a certain overlapping region exists in the acting ranges of the left millimeter-wave radar sensor and the right millimeter-wave radar sensor, one target vehicle can appear and is detected by the left millimeter-wave radar sensor and the right millimeter-wave radar sensor at the same time, detected targets need to be treated through the data fusion technology, all the targets detected in the coverage area are subjected to fusion treatment, whether the targets are targets in a left lane or targets in a right lane or targets running behind the vehicle in a current lane and the danger degrees of the target vehicles relative to the vehicle in the lane change process, i.e., whether the target vehicl
