4hw.com.cn: cars are becoming more and more popular. More and more people are thinking about how to start a favorite car. However, there are always some problems when buying a car, such as which configurations are useful and which are not. We have also ushered in a new wave of knowledge. In this issue, we still talk about the auxiliary configuration of vehicles.
Parking radar and reversing radar
The parking radar and reversing radar have the same principle. The reversing / parking radar can inform the driver of the surrounding obstacles with sound or more intuitive display, relieve the driver of the trouble caused by left and right visitation when reversing, and help the driver to clear the blind angle of vision and the lack of blurred vision, so as to improve the safety of reversing.
There are different types of parking and reversing radar prompts for different models. Some only have voice prompts, some have virtual image displays, and some have automatic parking and image functions. We will talk about these later.
For the radar with sound and analog display, the owner should have a familiar process at the beginning of use. For example, someone can hold the template behind the radar and slowly push it towards the radar. The personnel in the car can compare the actual distance with the external personnel according to the sound prompt or simulated real distance. After multiple comparisons, they will master the display distance of sound and analog radar. Of course, the radar is a machine after all. When reversing, it's better to get off the car and observe the driving environment to avoid unnecessary collision damage.
Some models with forward radar can be flexibly applied by car owners, especially when buying MPV and cross-border models, which can't see the front of the car, the models with front radar can help a lot in and out of the side and keep the distance between cars. As for the opening mode and speed of the radar, please read the operation manual in advance to prevent misoperation!
Visual reversing radar
In fact, the principle of the visual reversing radar is the same as that of the reversing radar. The difference is that the reversing image can see the image behind the vehicle through the display screen in the vehicle. The visual reversing radar can be divided into those with and without driving tracks, and some functions with obstacle display, which should be treated differently for new car users.
As there are some errors between the display of reversing image and the actual distance, it is recommended to adopt the same method as ordinary reversing radar to get familiar with the display distance and prevent unnecessary collision and scratch.
For the novice, the visual reversing radar with driving track and obstacle display function is more practical.
Panoramic camera
In order to solve the problem that the reversing image system can not take full care of the surrounding perspective, some manufacturers have developed panoramic cameras. The core of this system is to add multiple cameras at the front and side of the vehicle, so as to obtain real-time images around the vehicle.
It should be said that the model with panoramic camera improves the safety of vehicle moving and reversing, ensures the safety of surrounding environment and reduces the possibility of accidents for drivers.
