The car collision avoidance warning system is mainly used to assist the driver to avoid major traffic accidents such as high-speed and low-speed rear-end collisions, unintentional deviation from the lane at high speeds, and collisions with pedestrians. Helping the driver like a third eye, continuously detecting the road conditions in front of the vehicle, the system can identify and judge various potential dangerous situations, and use different sound and visual reminders to help the driver avoid or slow down collision accidents.
The car collision avoidance warning system is based on intelligent video analysis and processing, and its warning function is realized through dynamic video camera technology and computer image processing technology. The main functions are: vehicle distance monitoring and rear-end collision warning, forward collision warning, lane departure warning, navigation function, and black box function.Compared with the existing automobile anti-collision warning systems at home and abroad, such as ultrasonic anti-collision early warning systems, radar anti-collision early warning systems, laser anti-collision early warning systems, infrared anti-collision early warning systems, etc., the functions, stability, accuracy, humanization, The price has incomparable advantages. All-weather, long-term stable operation, greatly improving the comfort and safety of car driving.
1) Vehicle distance monitoring and early warning: the system continuously monitors the distance to the vehicle in front, and provides three levels of vehicle distance monitoring alarms according to the proximity to the vehicle in front;
2) Vehicle crossing line warning: When the turn signal is not turned on, the system generates a line crossing alarm about 0.5 seconds before the vehicle crosses various lane lines;
3) Forward Collision Warning: The system warns the driver that a collision with the vehicle in front is about to occur. When the possible collision time between the vehicle and the vehicle in front is within 2.7 seconds at the current driving speed, the system will generate sound and light warnings;
4) Other functions: black box function, intelligent navigation, leisure and entertainment, radar warning system (optional), tire pressure monitoring (optional), digital TV (optional), rear view (optional).
The current automobile forward collision warning millimeter wave radar mainly has two frequency bands of 24GHz and 77GHz. The Wayking 24GHz radar system mainly realizes short-range detection (SRR), which has been widely used in plant protection drones as height-fixed radars, while the 77GHz system mainly realizes long-range detection (LRR), or the two systems are used in combination to achieve long and short distances detection.
