Night Intelligent Assisted Driving System

Abstract

The invention relates to an intelligent night driver-assistance system.An infrared camera acquires a front road condition image of a vehicle in real time and transmits the image to a master control module through an image processing chip, a millimeter-wave radar transmits a detected target distance signal to the master control module, the master control module identifies information of the front road condition image of the vehicle and perform judgment in real time, starts an infrared light supplementing LED to improve the brightness of a target area and keeps original brightness of other areas when determining that the running safety of the vehicle is threatened, reduces the brightness of a target vehicle area for dazzle prevention, transmits processed image information to an image processing module in real time and displays the information through a displayer when determining that same-direction or opposite-direction target vehicles runs on the aspect of the front road condition of the vehicle; the master control module calculates and analyzes the received target distance signal and sends the real-time information of the road condition and alarm information to a voice prompting module.The intelligent night driver-assistance system can increase a detection distance and improve the imaging quality under the poor lighting conditions, such as night and rainy, snowy and haze days.

Description

technical field [0001] The invention relates to an intelligent assisted driving system at night, which belongs to the technical field of intelligent assisted driving of motor vehicles. Background technique [0002] With the continuous development of the economy and society and the improvement of people's living standards, people are increasingly dependent on cars for travel, and the accompanying traffic safety issues have become increasingly prominent. Under harsh conditions such as night, rain, snow, and haze, the driver's sight distance becomes smaller and the field of vision becomes narrower; when turning or changing lanes, the A-pillar between the front windshield and the front door glass will form a visual blind spot; When the two vehicles meet, if the other vehicle fails to turn off the high beam in time, it will cause a large blind spot for the driver. All of the above situations may cause the driver to misjudge and operate improperly, resulting in frequent accidents...
