The invention discloses a vehicle forward collision avoidance system based on infrared laser aid. The vehicle forward collision avoidance system based on infrared laser aid comprises an infrared laser, a camera, a DSP (Digital Signal Processor) data processor, a controller, an early warning device and a speed reduction executing mechanism, wherein the infrared laser and the camera are respectively connected with the DSP data processor; the DSP data processor is connected with the controller; and the early warning device and the speed reduction executing mechanism are respectively connected with the controller. According to the invention, Through the adoption of the vehicle forward collision avoidance system based on infrared laser aid, a target vehicle can be detected and a real-time distance between two vehicles can be calculated through the coordination of the camera and the laser; a forward collision avoidance purpose is realized through using the executing mechanism to control the vehicle to reduce the speed under hazardous conditions; problems that vehicle detection and identification function loss, low vehicle distance detection accuracy or the like caused by the traditional millimeter-wave radar or single camera technology are solved; and real-time performance, robustness and accuracy of the system under actual road environments are improved.
