[0005]
When measuring by ultrasonic echo, the sound wave is emitted and received by the probe, and the sound wave runs at the speed of sound, because the sound wave has phenomena such as reflection and refraction, so the ultrasonic radar is more interfered and the early warning effect is poor

The application provides an automotive anti-rear-end-collision early-warning method. A microwave radar sensor monitors a distance of a suspicious object arranged at the rear end of a vehicle; when thedistance of the suspicious object is monitored to be less than a preset first threshold, the following steps is performed: the microwave radar sensor obtains the distance of the suspicious object inreal time to obtain a distance sequence; the microwave radar sensor obtains the distance of the suspicious object in real time to obtain a first speed sequence; the speed of the vehicle is obtained inreal time to obtain a second speed sequence; steering data of the vehicle are obtained in real time to obtain a steering data sequence; according to the distance sequence, the first speed sequence, the second speed sequence, and the steering data sequence, a rear-end collision probability of the suspicious object is determined; and if the rear-end collision probability is greater than a second threshold, alarming is carried out. According to the provided method, the microwave radar sensor monitors the suspicious object and early warning is carried out based on the distance of the suspicious object, the speed of the suspicious object, the speed of the vehicle, and the steering data of the vehicle.
Description
technical field [0001] The present application relates to the technical field of radar data processing, in particular to an early warning method for preventing rear-end collisions of automobiles. Background technique [0002] In recent years, frequent traffic accidents in our country have caused casualties and property losses. The severe social situation has made people pay more and more attention to automobile safety. [0003] With the rapid development of computer technology, communication, and electronic technology, it has become possible to use electronic technology to detect vehicle driving environment and prevent traffic accidents through early warning. [0004] At present, most vehicles use ultrasonic waves, lasers, infrared rays, etc. to measure the distance between obstacles and cars. [0005] When measuring by ultrasonic echo, the sound waves are emitted and received by the probe, and the sound waves run at the speed of sound. Because the sound waves have phenomen...
