Information about Reverse Parking Sensors

Typically, Reverse Parking Sensors by the ultrasonic sensors (commonly known as probes), controller and display (or buzzer), etc. components. Reversing radar generally use the principle of ultrasonic ranging, under the control of the controller by the ultrasonic sensor firing signals when encountering obstacles, the resulting echo signals, sensors received echo signal by the controller, data processing, determine obstacle location, the distance from the monitor display and send to other warning signals, timely warning, so that motorists be aware of when reversing to make reversing easier. In a few years time, as technology development and user needs change, reversing radar, after a roughly six-generation development.



The first generation Reverse Parking Sensors through the speaker reminded. "Reversing Please note that"! Must have a lot of people still remember the sound, which is reversing radar, the first generation of products, and now only a small part of the commercial vehicles still in use. As long as the driver hung up reverse, it will ring to remind the attention of people around. In a sense, it is not directly help the driver, not a true reversing radar. Cheap, basic products are eliminated.

The second generation: The buzzer different voice prompts the driver. This is the real beginning of reversing radar system. Reverse, if the rear 1.8 m -1.5 m obstructions buzzer will start working. Buzzing sound more urgent, said the vehicle away from the barrier closer. But there is no voice prompts, nor from the show, although the drivers know there are obstacles, but obstacles are not sure how far away from the car on the driver very helpful.

Third Generation: Digital-band show a specific distance or distance range. This generation than the second-generation improved a lot, you can display rear obstacle distance from the body. If it is an object, at 1.8 m starting to show; if the people at a distance of about 0.9 m starting to show. This generation of products are two kinds of display, digital display products, from the figures show, while the band display products from the three kinds of color difference: green represents a safe distance; yellow warning distance; red dangerous distance, to stop reversing. The third generation of digital and band together, but more practical, but it is not installed in the car beautiful.
