Can inform the drivers surrounding obstacles with sound or more intuitive display, relieve the drivers parking, reversing, and starting vehicles.Defects, improve driving safety.What is the principle of reversing radar?Are there any blind spots in the reversing radar?Lets take a look with Xiaobian below
Principles of folding detection
The reversing radar is designed and developed based on the principle of bats that bats in the night without colliding with any obstacles.The probe is installed on the rear bumper. According to different prices and brands, the probe has two, three, four, six, eight, ten, and twelve, which is mainly installed on the front and rear bumpers.The probe can radiate at a maximum level of 120 degrees vertical 70 degrees, and search for targets up, down, left and right.Its biggest advantage is that it can explore obstacles that are difficult to see from the rear window than the bumper than the bumper, and report to the police, such as flower bed, road shoulders, and children who are playing behind the car.
The displayer of the reversing radar is installed on the rearview mirror, and it constantly reminds the driver how much distance is there when the object is behind. At the dangerous distance, the bee tweee began to tweet.The obstacles are approaching and parking in time.
When the gear rod is hung into the reverse gear, the reversing radar automatically starts to work, and the range of the ranging range is about 0.2 to 1.8 meters. Therefore, it is very practical to the driver when parking.
Reversing radar is equivalent to ultrasonic probe. Overall, ultrasonic probe can be divided into two categories: one is to produce ultrasonic waves by electrical methods, and the other is to produce ultrasonic waves in mechanical methods. In view of the more commonly used pieces of voltage ultrasonic generators,It has two electrical chips and a resonance plate. When the polarity is added with pulse signals, the frequency is equal to the inherent shock frequency of the piezoelectric chip, the pressure chip will resonateThis process of electrical signal has become the working principle of ultrasonic probe.In order to better study the ultrasonic and use, people have designed and manufactured many ultrasonic soundtakers, and ultrasonic probes are used to use on the use of car reversing radars.
This principle is used in a non -contact detection technology. It is used in the range of ranging simple, convenient and fast, easy to control real -time control, and the accuracy of the distance meets industrial practical requirements.The reversing radar is used for the ranging from the ranging. At a certain moment, the ultrasonic signal is issued. When the shot signal wave after encountering the measured object is received, it is received by the reversing radar.Calculating the transmission speed in the medium, this can calculate the distance between the probe and the detected object.
Blind radar blind area
Detective blind zone
Although the reversing radar brings us a lot of convenience, it cannot be excessively dependent, because the radar also has a blind spot. In the following cases, the radar will not respond:
Too low obstacles
Generally speaking, obstacles below the probe center may be ignored by the probe, and the closer the distance between the obstacle distance, the closer the distance between the parking space, this height value will be reduced, and the risk will increase.
Overdid obstacle
Due to the narrow sound wave signal emitted by the radar probe, there is a large blind spot in the detection of finer obstacles. Some roads are used to block the isolation pile of the vehicle. The cable steel cables on the electric pole are dangerous items.
The radar is used to detect obstacles, and there is a ditch behind the car, so the radar will never respond.
Parking skills
Non -"font parking space parking skills
1. Lock a parking space you want to park, and then continue to drive forward,
2. Adjust the horizontal distance between your car and parking line to about 1.5 meters.
3. The next step is to fill the direction, and then reverse the position,
4. If it is a large MPV, the starting position of the entry should be driven forward half of the parking space, and then the car can be reversed.
Line parking space parking skills
1. After selecting the parking space, drive the car forward, keep parallel to the car in front of the parking space, and control the horizontal distance at 30-50 cm at the same time.
2. After that, keep the direction unchanged and start to reverse slowly. When the external mirror on the right side is parallel with the B -pillar of the car,
3. When the straight line where your body is located and the straight line of the parking space is 45 degrees, stop reversing,
4. Then just pour in the left and full directions, but pay attention to the speed of speed.
Parking tips for oblique parking space
1. First of all, first determine the parking space you are entering. When driving the car to the left rear mirror is right to the left line of the next parking space, hit the steering wheel slowly.
2. Continue to move forward.
3. Pass the car, return to the wheel, slowly reverse the car, and stop the parking space smoothly.
