How to read the reversing instrument
With the continuous development of automobile technology, reversing sensors (reversing radar or reversing images) have become one of the important configurations of modern vehicles. It not only helps drivers complete reversing operations more safely, but also effectively reduces the occurrence of traffic accidents. This article will combine the hot topics and hot content in the past 10 days to give you a detailed introduction to the functions, usage and purchase suggestions of the reversing camera.
1. Functions and types of reversing instruments
Reversing instruments are mainly divided into two types: reversing radar and reversing images, each of which has its own focus on function:
| Type | Function | Advantages and Disadvantages |
|---|---|---|
| Reversing radar | Detect obstacles with ultrasonic waves and sound alarms | Low price and simple installation; but cannot display the specific location of obstacles |
| Reversing image | Display the rear view of the vehicle in real time through the camera | Intuitive and clear; but the price is higher and the installation is complicated. |
2. How to use the reversing instrument
1.Use of reversing radar: - When reversing, the radar will automatically detect obstacles behind you. - The closer to the obstacle, the higher the frequency of the alarm sound. - Pay attention to distinguishing the alarm sounds of different radars to avoid misjudgment.
2.Use of reversing image: - After engaging reverse gear, the central control screen will automatically display the rear image. - Pay attention to the auxiliary lines in the screen (such as trajectory lines and distance lines). - Avoid relying entirely on images, and still need to combine rearview mirror observation.
3. Suggestions for purchasing reversing instrument
Based on popular discussions and user feedback in the past 10 days, the following are the key indicators for purchasing a reversing camera:
| indicator | Suggestions | Popular brand reference |
|---|---|---|
| Detection distance | Choose a range of 1.5-2.5 meters to cover common reversing scenarios | Iron General, Hao Di |
| Display clarity | The resolution is at least 720P, and infrared function is required at night | Xiaomi, 70mai |
| Installation method | Give priority to non-destructive installation products to avoid damaging the original vehicle wiring. | 360, stare and shoot |
4. Frequently Asked Questions and Solutions of Reversing Instruments
1.False positive problem: Rain or snow may cause false alarms from the radar, so it is recommended to clean the sensor regularly. 2.Picture delay: The low-priced reversing image may be delayed, so you need to pay attention to the chip performance when purchasing. 3.Installation location: The camera should be installed in the center, preferably about 50-70 cm above the ground.
5. Future Trend: Intelligent Reversing System
The recently discussed smart reversing technology has begun to integrate AI algorithms, such as: - Automatic recognition of pedestrians and emergency braking - 3D panoramic image synthesis technology - Remote viewing of reversing images via mobile APP. These functions will become the core competitiveness of the next generation of reversing instruments.
Summary: Reversing instruments are an important tool to improve driving safety. Proper selection and use can significantly reduce the rate of reversing accidents. It is recommended that car owners choose products with matching functions based on their own budget and needs, and perform regular maintenance to ensure their normal operation.
