All-weather automobile radar anti-collision driving system

Abstract

The invention relates to a radar anti-collision driving system. The system is characterized in that: two sides of the front part of an automobile are provided with anti-side collision laser range finders; the front part is also provided with sonar horns; a sonar transducer is connected with the back of the sonar horns; the sonar transducer is connected with a syndrome all-weather automobile signal processor through an amplifier and a diode detector; a thermal infrared imager is arranged in the front of a cab; a digital signal processor TMS 320240 is adopted in hardware of a driving expert control system and the hardware integrates high-speed signal processing capacity of a DSP and a peripheral circuit suitable for motor control into a whole to directly control speed reduction, steering and braking of the automobile; and a driving expert system adopts an artificial intelligent forward inference engine program and programs by using an artificial intelligent language, namely an LISP language or a MATLAB language. The all-weather automobile radar anti-collision driving system can realize all-weather precise measurement and positioning of targets in front of the automobile, and automatically adjust speed, steering, and braking to fulfill the aim of safe driving.

Description

1. Technical field [0001] The invention relates to an all-weather automotive radar collision avoidance driving system. 2. Background technology [0002] With the increasing number of automobiles and the gradual development of expressways, automobile traffic accidents have increased sharply. Its main reason one is heavy rain and fog weather, and the 2nd, driver's misoperation, thereby be badly in need of car all-weather (can normally work as heavy rain and fog situation) accurate detection radar assisted driving system. The problems existing in the current state of the art at home and abroad are: the microwave radar is too large and cannot locate the target; the millimeter wave and laser have poor anti-rain and fog capabilities, and the ultrasonic reversing radar has a working distance of only a few meters and cannot locate the target; About 50 meters, and the rain and fog weather does not work. 3. Contents of the invention [0003] This patent is based on my previous pat...
