With the development of intelligent and automated trucks, the standards of trucks today are no longer the same. At the Beijing Auto Show in 2018, Foton Daimler unveiled the Auman EST 2.0 Super Truck, setting off a surge of upgrades to the high-end logistics market. Compared with other competitors, the reporter found that Auman EST2.0 has good strength in automation, intelligence, comfort and economy, especially in automation and intelligence, but it also takes the lead.
Auman EST2.0 Super Heavy Duty Truck was used as the masterpiece of Futian Daimler. Many active safety configurations were assembled. The reporter found that assistive driving technologies such as FCW collision warning, LKA lane keeping assist system, AEB automatic emergency braking system, ACC cruise control, etc. Auman EST2.0 can be seen, quite rich.

Standing in front of the car, we can see that in addition to the aerodynamic design of the front, LED daytime driving lights, the golden Fukuda standard with a bottom lamp, there is also a high position camera hanging on the front windshield, see Like driving recorder, in fact, it also integrates a distance camera, with the microwave radar below the license frame, which is a set of highly integrated, complete AEB automatic emergency braking system.

It has to be said that in recent years, the wide application of electronic stability programs such as ABS and ESP in trucks, together with newer brake systems and retarders, has increased the overall safety of trucks by a further step. Vehicles have become more available in extreme conditions. Control, braking distance is shorter. However, traffic accidents are sudden. When a driver can't make emergency brakes quickly because of drowsiness, devastation or other reasons, then no matter how powerful the electronic stability system and braking system is, it is no use. In order to provide better intelligent solutions, AEB automatic emergency braking system came into being.
AEB automatic emergency braking system
AEB (Autonomous Emergency Braking) is an automotive active safety technology that consists of three major modules, including the control module (ECU), ranging module, and brake module. The core of the ranging module includes radar, face recognition technology and video system. It can completely distinguish the specific object in front of the vehicle, whether it is a moving car or a stationary object.
AEB Control Module (ECU)
AEB work process:
· Somewhat wrong, prepare early (radar measures the distance to the vehicle or obstacle, and then use the data analysis module to compare the measured distance with the alarm distance and safety distance).
· It's a little dangerous, so let's shout it! Buddy! Be careful! (When the distance is less than the alarm distance, a warning light is issued to alert the driver)
· No response? Let's take a brake with you! (Start automatic implementation of engine brake control or service brake control)
· The distance is a bit closer, then step on it! (Continued braking while alerting the driver)
Can't hold it, step on it! (If the driver has not taken corresponding measures at this time, the AEB control system will calculate and confirm that the collision has been unavoidable according to the current situation, and will automatically perform emergency braking until the vehicle stops.)
AEB work process
In terms of current technology, advanced AEB systems can be operated at relatively high speeds, such as within 40 and 50 kilometers per hour, and can be stopped in an emergency situation. Ordinary, you can brake within 30 kilometers per hour; entry-level, can stop within 20 kilometers per hour. However, not all AEBs can recognize pedestrians, even if the recognition vehicles cannot achieve a 100% recognition rate. However, some European manufacturers already have pedestrian collision prevention technology.
Heavy trucks with AEB system are tested
In addition to dealing with front-end chasing and pedestrians, this system is also quite effective for another type of situation: the notorious Gasser. People like Garceouse are often pinpointed. If you don't pay much attention to the distance to the vehicle in front, you have to plug it in. If you react slowly and beat it half-a-time, you may get rubbed. Plus, the blind area of ​​the truck itself is very large. It caused an accident. At this time, if there is an automatic braking system, such events can be largely avoided.
All in all, the automatic emergency braking system is not a 100% anti-stalking system, but it can reduce the probability of rear-end collisions with a high probability. As long as the brakes are applied, even if the rear-end collision is not stopped, the consequences will be lower than without a brake. With the maturity of technology, it is believed that the AEB system will be more reliable and bring more safe travel to truck drivers.
However, for the intelligent and automated development of trucks, the AEB automatic emergency system plays an irreplaceable role. According to the active safety configuration carried by Auman EST2.0, it is not difficult to see that this type of automation and intelligent equipment of the AEB system is in line with the current market demand for assisted driving, and is also an important part of realizing automatic driving in the future.
