Automobile active anti-collision early warning system based on millimeter-wave radars

The invention discloses an automobile active anti-collision early warning system based on millimeter-wave radars. The automobile active anti-collision early warning system mainly comprises a signal acquiring and processing module I, an automobile information acquiring module II, a judgment recognition module III, a man-machine interaction module IV and an execution system module V. The signal acquiring and processing module I utilizes the millimeter-wave radars I-1 to obtain the speed, a distance and an azimuth angle of a target X relative to an automobile Z and outputs the information processed by a processor I-2. The automobile information acquiring module II utilizes an ABS wheel speed sensor II-1 to obtain the automobile speed and road adhesion coefficient of the automobile Z and outputs the information processed by an auxiliary II-2. The judgment recognition module III judges the type of the target X, transmits the target type to the man-machine interaction module IV and transmits a control strategy to the execution system module V. By taking corresponding avoidance control measures, the automobile active anti-collision early warning system can remind a drive to take the measures so as to ensure safe and comfortable driving in advance of enough time, effectively recognize a dangerous target, remind the driver and improve the system safety.
