Reversing radar

The reversing radar is a safety auxiliary device when the vehicle is parked or reversing, and can inform the driver of the obstacles in the surroundings with sound or more intuitive display, and cancels the driver's parking, reversing and starting the vehicle. Confused and help the driver clear the flaws of the blind spots and blurred vision, improve driving safety.

In general, a reversing radar consists of an ultrasonic sensor (commonly known as a probe), a controller, and a display (or buzzer). Reversing radar generally adopts the principle of ultrasonic distance measurement. Under the control of the controller, the sensor emits ultrasonic signals. When an obstacle is encountered, an echo signal is generated. After the sensor receives the echo signal, it is processed by the controller and judged. The position of the obstacle is displayed by the display and other warning signals are issued to get a timely warning so that the driver can know what to do when he is reversing the car, making reversing easier. In the past few years, with the development of technology and changes in user needs, reversing radar has undergone roughly six generations of development.

First generation: Reminder by horn when reversing. "Reverse, please note!" Presumably many people still remember this sound. This is the first generation of reversing radar products. Now only a small portion of commercial vehicles are still in use. As long as the driver hangs upside down, it will ring, alerting people around. In a sense, it does not directly help the driver, not the real parking sensor. The price is cheap, basically belongs to eliminated products.

The second generation: the use of a buzzer sounds different drivers. This is the real beginning of a reversing radar system. When reversing, the buzzer will start working if there is an obstruction at 1.8 meters to 1.5 meters behind the car. The more buzzing the beeps, the closer the vehicle is to the obstacle. However, there are no voice prompts and there is no distance display. Although the driver knows that there are obstacles, he can't be sure how far the obstacles are from the car, and it does not help the driver.

The third generation: digital bands show specific distances or distance ranges. This generation of products is a lot more advanced than the second generation and can show the distance of the obstacle behind the car. 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. There are two display modes for this generation of products. The digital display products display distance numbers. The band display products are distinguished by three colors: green represents the safety distance, yellow represents the warning distance, and red represents the dangerous distance. It is necessary to stop the reversing. The third generation of products combines digital and band, but it is more practical, but it is not very beautiful to install in the car.

The fourth generation: LCD screen dynamic display. This generation of products has a qualitative leap, especially when the screen display begins to appear dynamic display systems. Do not hang reverse, as long as the car is started, the car pattern will appear on the monitor and the distance around the obstacles around the vehicle, the color is clear and beautiful, beautiful appearance, can be directly affixed to the dashboard, the installation is very convenient. However, although the appearance of the liquid crystal display is exquisite, the sensitivity is high, and the anti-interference ability is not strong, so false alarms are also more.

Fifth generation: Magic mirror reversing radar. Combining the advantages of previous generations of products, using the latest bionic ultrasound radar technology, coupled with high-speed computer control, can accurately detect obstacles within 2 meters within 24 hours, and use different levels of voice prompts and intuitive display to remind the driver . Magic mirror reversing radar can integrate functions such as rear-view mirror, reversing radar, hands-free telephone, temperature display, and air pollution display in the car, and has designed the voice function. Because its shape is a reversing mirror, it can be installed directly in the position of the rearview mirror in the car without occupying the space inside the car. And the color styles are varied and can be matched according to individual needs and interior decoration.

The sixth generation: integrated audio and video systems. It has added a lot of functions on the basis of the fifth generation of products, and it belongs to the sixth generation of products, which is specially produced for high-end cars. From the appearance point of view, this system is more refined and elegant than the fifth-generation product; from a functional point of view, it not only has all the features of the fifth-generation product, but also integrates the audio-visual system that is available in high-end cars and can be displayed on the monitor. Watch DVD video.

At present, there are as many as 20 reversing radar brands on the market, ranging in price from a hundred dollars to one or two thousand dollars. The selection of reversing radars can be considered from the following aspects: function, performance, appearance, quality, installation, and price.
