Recently, Ideal claimed that its AEB can brake at a speed of 120km h, and Yu Chengdong announced that Huawei's AEB can brake at a speed of 80km h. These two buddies kicked off the AEB race.
So I want to ask, is it really safer to have a higher stopping speed on AEB?Are these two players misleading?
First of all, the braking speed is a design logic problem, different brands have different design concepts, not that the higher the braking speed, the more advanced the technology. Volvo, for example, was the first to introduce AEB technology, which is designed to brake at speeds below 60 km/h, because secondary hazards caused by high-speed braking are also considered.
Secondly, I think this should be looked at by scenario, the first scenario is acceptable if there are pedestrians (pets), two-wheelers, three-wheelers and four-wheelers in front of them, because major safety accidents can be avoided.
In the second scenario, if there are tree branches, cardboard boxes and plastic bags in front of you, this scenario stops at high speed, which is of little significance.
In the third scenario, if there are many vehicles trailing at high speed behind the car, high-speed braking may cause a serious rear-end accident. Whether or not it is time to brake depends on the specific situation at the time, not a one-size-fits-all high-speed braking...
The best way to solve the third scenario is to call the police in time, including the first pair of drivers to remind him to take over the vehicle, remind him to brake or change lanes in time. Second, call the car behind me and remind me to brake. Third, give an alarm (double flashing or honking) to obstacles or pedestrians and vehicles in front of them to remind them to take measures in time.
Therefore, AEB braking can not simply increase the speed as high as possible, but also cooperate with a comprehensive alarm mechanism.
Allowing the driver to actively control the vehicle to avoid obstacles is much more important than simple high-speed braking, much smarter, much safer, and the user experience will be better.
Therefore, the higher the AEB braking speed, the better, on the contrary, the alarm mechanism before the AEB starts, the more comprehensive the better. This is the ideal of the AAB OTA value of the like, from the content of the press conference, it is a warning to vehicles, pedestrians, cyclists, tricycles, and general obstacles before the launch of the AEB. This design concept is safe and reasonable, but the actual performance still needs to be measured.
In addition, I still think that 120km/h braking is not a good design, and if someone in the car is not wearing a seat belt, someone may fly out. The experience for the driver will not be great either.
When it comes to Huawei's AEB generalization capabilities, instead of braking at high speed on tree branches, cartons, and plastic bags, and letting less smart cars make judgments, it is better to call the driver in various ways. Let smarter people do the judgment and execution.
Of course, the combination of stronger generalization capabilities and more comprehensive alarm mechanisms will definitely make AEB both safe and smart.
Am I right?Welcome to discuss the bricks....
