Abstract

The invention discloses an automobile anticollision intelligent early warning system based on millimeter-wave radars. The automobile anticollision intelligent early warning system based on the millimeter-wave radars comprises an automobile body, the millimeter-wave radars, a Beidou satellite positioning system, an inertial navigation system, automobile door trigger switches, automobile lock control switches and a main control module, wherein the millimeter-wave radars, the Beidou satellite positioning system, the inertial navigation system, the automobile door trigger switches, the automobilelock control switches and the main control module are arranged on the automobile body; the millimeter-wave radars are uniformly installed on the periphery of the automobile body; the Beidou satellitepositioning system, the inertial navigation system and the millimeter-wave radars are correspondingly and electrically connected with a signal amplifier, a demodulator and the main control module in sequence; the automobile door trigger switches are installed on opening handles on the inner parts of four automobile doors of the automobile body and are connected with the main control module; and the automobile lock control switches are installed at hinge joint positions of the four automobile doors of the automobile body and the automobile body to restrict the opening and closing of the automobile doors. According to the automobile anticollision intelligent early warning system based on the millimeter-wave radars, the conception is original, the detection reliability is high, the algorithmic complexity and the equipment cost of the complete set of the system are reduced greatly, the detection accuracy is improved greatly on year-on-year basis, and the safety of driving is improved.

Description

technical field [0001] The invention relates to the technical field of vehicle detection and road traffic early warning, in particular to an intelligent vehicle anti-collision early warning system based on millimeter wave radar. Background technique [0002] With the improvement of people's living standards, the demand for cars is increasing, and there are more and more traffic accidents, especially frontal rear-end collisions and side collisions of cars account for a very large proportion, especially in bad road conditions and weather case. Car rear-end collisions caused by cars with limited vision in blind spots, side collisions with other vehicles or pedestrians also account for a large proportion. Over the past few decades, people have mainly studied passive safety technologies (safety equipment systems that protect occupants when an accident occurs), such as airbags and seat belts. There is little research on active safety technology (effective equipment to avoid traf...
