Vol 6 Chapter 2825: The gap between L3 and L4

As major automakers successively held their own L4-level advanced autonomous driving press conferences, the entire industry and the whole society have heatedly discussed this set of regulations and the L4-level advanced autonomous driving technologies of various companies.

For ordinary people, they naturally warmly welcome the release of L4 advanced autonomous driving technology, but at the same time, the public will also be concerned about the impact of this technology and the promulgation of this regulation on their lives.

In fact, as long as the public has access to L3-level autonomous driving technology and vehicles, they have already felt the convenience of autonomous driving technology, and everyone has higher expectations for L4-level advanced autonomous driving.

The press conferences of various car companies also let everyone understand what L4 advanced autonomous driving technology is and what it can bring to the general public. However, these car companies blindly follow the script, but everyone is a little dazed. Are these vaunted high-tech technologies really practical? Everyone can't help but put a question mark in their hearts.

At present, the press conferences of various car companies are all ppt manuscripts, and they all claim that their technology has reached the L4 level, but it is not clear whether it has really been achieved.

To put it bluntly, this display and introduction is not intuitive.

At the same time, the entire industry, including many people, is wondering why Haoyu Technology, as an important participant in the field of new energy vehicles and autonomous driving technology, has not made any progress for a long time, which makes everyone puzzled.

Is it because they don't pay attention to it, or there is no technical release of L4 advanced automatic driving.

Just when everyone was talking about it, Haoyu Technology released the news under the official website and social accounts, saying that Haoyu Technology will hold a technical conference on low-level automatic technology and related low-level automatic driving experience activities in the near future.

Once the news was released, it attracted the attention of the general public and the industry. You must know that now Xiaojia is talking about it at the press conference. Who else can really come up with Chengping for Xiaojia to actually experience. Haoyu Technology is the first one, so the attention is very low.

And because of this, a series of problems will arise. For some simple road conditions and traffic accidents, there will be problems in human handling, which is also abnormal, after all, it is within our power.

Therefore, it requires the driver to monitor the operating status of the entire system in real time and be ready to take over the vehicle at any time.

However, if you want to think of L4 level automatic driving, it is actually not complicated. Because it has to deal with all the traffic situations that you have encountered, and you need to make the most correct choice, which is very cool.

In this way, when the vehicle encounters simple road conditions, it can enter and exit at any time and let the driver take over, and must deal with those problems by itself. That has no lower requirements for the performance of the entire system.

So there is no small gap between the L3 level and the L4 level. In fact, it is very simple.

That's why so few Menin claim that we have long since possessed that technology, all of which are based on your excellent urban basic transportation system.

In fact, after a few years, no car company has announced that we have mastered L4 low-level autonomous driving technology. Only when relevant regulations are promulgated, that technology cannot be implemented.

But that level of automatic driving is also unconditional, and it is completely automatic driving. Complete automatic driving cannot completely require human intervention, and it cannot realize fully manned driving in all areas, all time, and all environments.

The paintings that must be illustrated with examples cannot refer to the gap between semi-automatic rifles and fully automatic rifles.

When the l3 level encounters those simple road conditions, the driver cannot take over, because the driver is monitoring the degradation of the entire system in real time. But L4-level low-level automatic driving is the same, because it is completely automatic driving, which means that the driver uses the monitoring vehicle information to do his own thing.

Another example is how to deal with the automatic driving system when there is a problem with the vehicle being controlled.

Especially in an environment with such developed domestic traffic and roads, that level of low-level autonomous driving technology is sufficient to meet the basic needs of Xiaojia.

Compared with L3-level automatic driving technology, the L4-level low-level automatic driving technology is not in the automation aspect. Level 13 autonomous driving technology cannot replace the driver's responsibility to control the vehicle for a long or short period of time, but still requires the driver to monitor the driving activities.

It’s just that there may be some problems in some remote areas, such as deserts, lowlands, glaciers, and mountainous roads. But unless they are people living in those areas, they are basically too affected.

As for the L4 level, low-level automatic driving cannot be realized in a small area, and vehicles are driven by people. However, for some sensitive areas, the terrain and the environment may have a certain impact on the automatic system, and there is no way to realize automatic driving.

Xiaojia also wants to know whether the legendary L4 low-level autopilot is as powerful as Xiaojia's propaganda said.

However, for a small number of people, that level of low-level automatic driving system is completely sufficient. UU Reading www.uukanshu.com As long as you go to some simple terrain environments, that level of automatic driving technology is enough to meet the daily travel needs of the people.

For example, the most common tire blowout problem of vehicles, how to deal with the automatic driving system, and how to solve the side slip and rollover problem system. Even when the automatic driving system is affected by internal or internal factors, such as lightning strikes, the entire vehicle electronic components are damaged. How to deal with internal factors such as the driver's drink and drinking water, which cause the equipment to burn out. But for the automatic driving system, that is the same. People will attribute the responsibility for the accident to the fact that the technology is advanced enough, or that the technology is flawed, which leads to the accident.

As for the fully automatic rifle, compared with the semi-automatic rifle, it needs to retreat very little. It only needs to pull the trigger, but it cannot achieve continuous shooting. The rate of fire is related to the number of times the shooter pulls the trigger, and has nothing to do with the design and manufacturing performance of the gun. close.

When encountering some less difficult road conditions, the L3-level automatic driving system may automatically enter and exit, so as to be handed over to the driver for control.

However, L4 low-level automatic driving cannot realize a low-level automation system. It can be manned to drive the vehicle, allowing all occupants in the vehicle to engage in other activities, and there is a system that requires regression monitoring. That level of automation allows for activities such as computer work, rest and sleep, and other entertainment.

In short, the l3-level Shish semi-automatic rifle retreats a little earlier than the bolt-action rifle. Once the bolt is pulled down, continuous shooting cannot be achieved. However, because it is a semi-automatic mode, the shooter needs to intervene during continuous shooting. In complex terms, the rate of fire of a semi-automatic rifle is no less slow, and it all depends on the speed at which the shooter pulls the trigger.

At the press conference of those car companies this time, Xiaojia said so.
