Reversing radar is a parking safety auxiliary device for cars. It can inform the driver of the surrounding obstacles by sound or more intuitive display, eliminating the trouble caused by the driver looking around when parking and starting the vehicle, and helping the driver to eliminate the defects of blind spots and blurred vision, thus improving driving safety.
After five years of development, the reversing radar system has undergone six generations of technical improvements. Whether in terms of structure and appearance, or in terms of performance and price, these six generations of products have their own characteristics. The most commonly used are digital display, screen display and magic mirror reversing radar. The first
generation of reversing horns reminds
"Pay attention when reversing"! I believe many people still remember this sound. This is the first generation of reversing radar products. Now only a small number of commercial vehicles are still using it. As long as the driver puts the reverse gear on, it will sound to remind people around to pay attention. In a sense, it does not directly help the driver and is not a real reversing radar.
Comment: When the car is in the reversing state, the voice prompts passers-by to be careful, but the price is cheap and it is an obsolete product.
The second generation of roarers prompts
that this is the real beginning of the reversing radar system. When reversing, if there is an obstacle 1.8 meters to 1.5 meters behind the car, the roarer will start working. The more urgent the roar, the closer the vehicle is to the obstacle.
Comments: There is no voice prompt and no distance display. Although the driver knows there is an obstacle, he cannot be sure how far the obstacle is from the car, which is not very helpful for the driver.
The third-generation digital band display is
much better than the second generation. It can display the distance between the obstacle behind the car and the car body. If it is an object, it starts to display at 1.8 meters; if it is a person, it starts to display at a distance of about 0.9 meters.
This generation of products has two display modes. The digital display product displays the distance number, while the band display product is distinguished by three colors: green represents the safe distance, indicating that the obstacle is more than 0.8 meters away from the car body; yellow represents the warning distance, indicating that the distance to the obstacle is only 0.6~0.8 meters; red represents the dangerous distance, indicating that the distance to the obstacle is less than 0.6 meters, and you must stop reversing.
Comments: The third-generation product combines digital and band, but it is more practical, but it is not very beautiful when installed in the car.
The fourth generation of LCD screen display
products has a qualitative leap, especially the screen display began to appear dynamic display system. No need to put the reverse gear, just start the car, the car pattern and the distance of obstacles around the vehicle will appear on the display.
Comments: Dynamic display, clear and beautiful colors, beautiful appearance, can be directly pasted on the dashboard, very convenient to install. However, although the LCD display has a delicate appearance, it has high sensitivity and weak anti-interference ability, so there are more false alarms.
The fifth generation of magic mirror reversing radar
combines the advantages of previous generations of products, adopts the latest bionic ultrasonic radar technology, and is equipped with high-speed computer control. It can accurately detect obstacles within 2 meters all day and night, and remind the driver with different levels of sound prompts and intuitive displays.
The magic mirror reversing radar integrates multiple functions such as rearview mirror, reversing radar, hands-free phone, temperature display and in-car air pollution display, and designs voice function. It is a more advanced reversing radar system on the market.
Comments: Because its appearance is a reversing mirror, it can be directly installed in the position of the reversing mirror in the car without taking up space in the car.
The sixth generation of new products has more powerful functions. The
sixth generation of products has added many new functions based on the fifth generation, and is specially produced for high-end cars.
Comments: From the appearance point of view, this system is more refined and elegant than the fifth generation product; from the functional point of view, in addition to all the functions of the fifth generation product, it also integrates the audio and video system of high-end cars, and can watch DVD images on the monitor.
