What Principle Does the Reversing Radar Use?

1 Answers

Reversing radar operates on the principle of ultrasonic distance measurement, which is designed and developed based on how bats fly at high speeds in the dark without colliding with any obstacles. The reversing radar consists of components such as ultrasonic sensors (probes), a controller, and a display (or buzzer). Under the control of the controller, the sensor emits ultrasonic signals. When encountering an obstacle, an echo signal is generated. The sensor receives the echo signal, and the controller processes the data to determine the position of the obstacle. The display then shows the distance and issues other warning signals, providing timely alerts. This allows drivers to have a clear "measure" while reversing, making the process easier and safer. The reversing radar is an auxiliary device for car parking. It informs the driver about obstacles behind the vehicle through sound or a more intuitive display, eliminating the troubles caused by nearsightedness when parking or starting the vehicle. It also helps drivers eliminate blind spots, enhancing driving safety. After installing a reversing radar, the driver no longer needs to look back to know if there are obstacles behind the car. It can also display the exact distance of obstacles and provide timely warnings within a dangerous range, avoiding hazards caused by poor rear visibility. It is particularly useful for unseen steps, low walls, railings, parking in tight spaces, and nighttime reversing. In the past, reversing radar products were only suitable for installation on sedans and became standard equipment for high-end cars. Now, new-generation reversing radars have seen significant improvements in probes, making them compatible with various vehicle types such as station wagons, MPVs, jeeps, or off-road vehicles with added bumpers. This has led to the gradual popularization of reversing radars in other vehicle categories. Additionally, modern reversing radars not only provide audible alerts but also allow optional displays to show the scene behind the vehicle, indicating distance and judging direction. The sound alarm features an adjustable switch, allowing users to increase, decrease, or turn off the sound based on personal preference.

How to check if ETC is working properly?

ETC status can be checked through the following methods: 1. Remove the card and insert the chip side into the electronic tag. When you hear a "beep" sound and the electronic tag screen displays "Debit Card" or "Balance", it means you can normally pass through the ETC lane. 2. If the ETC card insertion shows messages like "Electronic Tag Invalid" or "No Card Inserted" on the electronic tag, it indicates an abnormality with the electronic tag. You need to visit an ETC service outlet for reactivation and reinstallation. 3. Additional information: ETC works through dedicated short-range communication between the vehicle-mounted electronic tag installed on the windshield and the microwave antenna in the ETC lane at toll stations. It uses computer networking technology for background settlement processing with banks, allowing vehicles to pay highway or bridge tolls without stopping at toll stations.
