The invention discloses a lane changing assistance early warning system. A right rear radar sensor and a left rear radar sensor used for detecting the two sides of the rear area are arranged on the two sides of a vehicle respectively, the right rear radar sensor and the left rear radar sensor output detection signals to a main control unit through a CAN bus, and the main control unit outputs a warning signal to a warning control unit. The early warning system is realized based on a lane changing assistance control unit of a single-chip microcomputer system and the DSP-based millimeter-wave radar sensors installed on the two sides of the rear area of the vehicle, and communication between the lane changing assistance control unit and the millimeter-wave radar sensors is achieved through the CAN bus; furthermore, the early warning system can be expanded by adding algorithms and radar modules, the expandability of the system is improved, and then an active safe system capable of achieving rear collision prevention, door opening warning and front collision prevention is obtained.
