Vehicle front ranging monitoring system
Working principle of vehicle front ranging monitoring system
The English full name of the vehicle Front ranging monitoring system is Front.
Auxiliary, the system uses both camera and radar for detection. The radar is responsible for detecting the farthest range in front of the vehicle150m, and the camera is responsible for the vehicle dynamics within 55m in front. The fusion of radar and camera signals can identify vehicles, pedestrians and bicycles. When the system detects an obstacle within a safe distance and judges that it may collide with it, the warning light in the instrument in front of the steering wheel, similar to the brake light, will light up first to remind the driver to pay attention. If the risk is high, it will give a sharp buzzer alarm. If the risk of collision is still increasing after warning, AEB automatic emergency braking system will be used. Without warning, the system will actively intervene in emergency braking to avoid or mitigate accidental collision and minimize collision damage. Escort the safety of car owners on urban roads.
Here are two screenshots of this feature introduced in ID4. X electronic vehicle manual as a gesture.

Main components of vehicle front ranging monitoring system
Medium range radar
The English abbreviation MRR is millimeter wave radar. Its main function is to measure the distance. The working principle of radar sensor is the echo time of bat ranging.
Flight (abbreviated as TOF) measurement method measures the distance between the obstacle in front and the vehicle itself. The frequency of medium-range radar for vehicles is generally 24GHZ, and the measuring range is about150m. Another well-known application of this radar is adaptive cruise (ACC) detection. That is to say, it can be used not only for ACC function in the long-distance detection range, but also for the detection of the front ranging monitoring system in the short distance such as 30-50.

Multifunctional camera
Forward-looking multi-functional high-definition camera plays an important role in automobile assisted driving. It can detect objects and people in front of the car at any time. Thanks to image recognition and artificial intelligence calculation, multi-kinetic camera can be used in lane keeping system, traffic sign recognition system, intelligent headlight system and distance monitoring system mentioned today.
Multifunctional camera
Take Volkswagen ID4 as an example. Take X as an example, the medium-range radar is installed behind the middle bumper in front of the vehicle, and the multi-function camera is integrated in the inner rearview mirror bracket above the windshield of the vehicle.
Forward ranging monitoring system and CNCAP and CIASI
As an important test content of vehicle auxiliary safety index, the front monitoring system is involved in the tests of CNCAP and CIASI, two major domestic automobile safety rating agencies.
Taking CIASI test as an example, there are five auxiliary safety tests for vehicles, 1, vehicle-to-vehicle emergency braking; 2. Pedestrians and drivers brake urgently; 3. Lane assistance system; 4. Headlight system; 5. Emergency rescue service system. The full score is 1 14, of which 1, 2 is related to the front ranging monitoring system, accounting for 78 points.
ID4。 X of SAIC Volkswagen
Pro Extreme Long Life Edition is equipped with a front ranging monitoring system. 202 1, item 1 scored 2 1 (out of 22), and item 2 scored 53 (out of 56). The data and picture contents are in official website, CIASI.

Setting of distance measurement monitoring system in front of vehicles
The distance monitoring system in front of the vehicle is turned on by default, but it can also be set in the central control screen of the vehicle.
Go, ID4. X, for example, the setting interface is as shown in the figure.
