In recent years, with the gradual popularization of assisted driving technology, it not only provides convenience for people’s daily travel, but also brings some new safety risks.
Frequently reported traffic accidents make the safety of auxiliary driving a hot topic of public opinion.
Among them, whether it is necessary to be equipped with auxiliary driving system sign lights outside the vehicle to clearly indicate that the driving status of the vehicle has become the focus of attention.
What is the auxiliary driving system sign light, the so-called auxiliary driving system sign light refers to a special lamp installed on the outside of the vehicle.
Through the specific installation location and color, it clearly indicates to other vehicles and pedestrians on the road that the auxiliary driving system is controlling the operation of vehicles, so as to enhance the perception and interaction of road users.
The purpose of this paper is to improve the safety of road traffic and reduce the traffic accidents caused by misjudging the driving status of vehicles.
Its working principle is based on the internal sensor and control system of the vehicle, when the vehicle turns on the auxiliary driving function, the system will automatically activate the sign lights to remind other road users to pay attention.
There are few applications of auxiliary driving system sign lights dominated by car enterprises, ideal L9 models equipped with auxiliary driving system lights and ideal L7 models equipped with auxiliary driving system lights.
At this stage, because there is no mandatory national standard requirements, among the models on sale in the domestic automobile market, only the models under the ideal car are actively equipped with auxiliary driving system sign lights, and the color of the light is blue-green.
Take the ideal L9 as an example, the whole car is equipped with five sign lights, four at the front and one at the rear (the ideal L7 has two).
This sign light is available on both the ideal AD Pro and AD Max models.
It is understood that in the default state, when the vehicle turns on the auxiliary driving system, the sign lights will be lit automatically.
It is important to note that this feature can also be turned off manually.
From an international perspective, there are no relevant standards or norms for the sign lights of the auxiliary driving system in various countries, and most of them are assembled by automobile companies on their own initiative.
In the case of Mercedes-Benz, for example, after being allowed to sell vehicles with Drive Pilot in California and Nevada in the United States, it took the lead in adding turquoise lights in Mercedes-Benz S-Class and Mercedes-Benz EQS models, which will be turned on at the same time to remind other vehicles and pedestrians on the road, as well as traffic law enforcement officers.
It is not difficult to find that despite the rapid development of assisted driving technology around the world, there are still some deficiencies in relevant supporting standards, and the vast majority of automobile enterprises focus on technology research and development and product marketing.
insufficient attention has been paid to key configurations related to road safety, such as auxiliary driving system lights.
It is imperative to improve road driving safety and install auxiliary driving system sign lights.
Mercedes-Benz EQS models equipped with auxiliary driving system sign lights (source: Mercedes-Benz official), in fact, the most fundamental reason for installing auxiliary driving system sign lights is to reduce the incidence of traffic accidents and improve road driving safety.
From a technical point of view, although the current domestic auxiliary driving system does not reach the L3 level of “conditional autopilot”, it is very close in terms of actual function.
Before that, some car companies said that the auxiliary driving level of their new car was L2.99999. Class, infinitely close to L3.
Zhu Xichan, a professor at the Automotive School of Tongji University, believes that the installation of driving assist system sign lights is meaningful for intelligent networked vehicles, and now many L2 + vehicles actually have L3 capabilities.
some drivers will form L3 use habits in the actual use of the car, such as selling for a long time, off-foot driving, and so on, which will cause some safety risks.
Therefore, when turning on the driving assistance system, it is necessary to give a clear hint to other road users outside.
Earlier this year, a car owner turned on the auxiliary driving system while driving at high speed.
as a result, when changing lanes, he mistook the billboard in front of him for an obstacle and then slowed down to a stop, causing the rear-end vehicle to avoid rear-end collision.
Just imagine, if the owner’s vehicle is equipped with an auxiliary driving system sign light and is turned on by default, it is bound to give a clear indication to the surrounding vehicles that I have turned on the auxiliary driving system.
After being prompted, drivers of other vehicles will be alert and take the initiative to stay away from or maintain a greater safe distance, which may be able to avoid the occurrence of this accident.
In this regard, Kerry Saichi Consulting Senior Vice President Zhang Yue believes that it is necessary to install external signs for vehicles with driving assistance functions.
At present, the penetration of vehicles equipped with L2+ driving assistance system is increasing, and there is a high probability of driving vehicles with L2+ system turned on on the road, but it is impossible to judge from the outside.
If there is a sign light outside, other vehicles on the road will have a clear understanding of the driving condition of the car, which will cause vigilance and will be more careful when following or parallel with the car to maintain a reasonable safe distance.
In fact, similar warnings are not uncommon.
The most well-known is the “internship logo”.
According to the requirements of the provisions on the Application and use of Motor vehicle driver’s license, the driver of a motor vehicle shall be an internship period of 12 months after obtaining a driver’s license, during which time he shall paste or hang a uniform pattern of “internship sign” on the back of the vehicle.
It is believed that most experienced drivers have the same feeling, but those who encounter the “internship sign” on the rear windshield of the vehicle show that the driver is a “novice”, so they generally stay away from this kind of vehicle.
or set aside enough safe distance when following the car or overtaking.
The same is true for the assisted driving system.
The car is a closed space.
If there is no obvious hint outside the vehicle, other vehicles and pedestrians cannot clearly judge whether the vehicle is being driven by a person or by the auxiliary driving system.
It is easy to lead to negligence and misjudgment, thus increasing the risk of traffic accidents.
The standard needs to be improved the sign lights of the auxiliary driving system should have laws to follow, so, since the auxiliary driving system sign lights are so important, does the country have any relevant policies and regulations to regulate them? In fact, at the present stage, only the local regulations issued by Shenzhen, the regulations on the Administration of Intelligent Network cars in Shenzhen Economic Special Economic Zone, have clear requirements for the configuration of sign lights, stipulating that “in the case of self-driving, cars with self-driving mode should be equipped with external indicators of self-driving mode as a hint.
” However, this rule is only valid for three types of intelligent Internet-connected cars with conditional self-driving, highly self-driving and fully self-driving, that is, only for models of L3 and above.
In additionIn September 2021, the Ministry of Industry and Information Technology issued “Automobile and trailer Optical signal Devices and Systems” (draft for soliciting opinions).
As a national compulsory standard, it added the requirement of “self-driving sign lights”.
The proposed implementation date is July 1, 2025.
However, the country’s mandatory standards are also aimed at models of L3 and above.
It is undeniable that the development of L3 autopilot has begun to speed up, but at this stage, the domestic mainstream auxiliary driving system is still concentrated in L2 or L2 +.
According to the data of the Federation of passengers, from January to February 2024, the loading rate of L2 and above auxiliary driving functions of new energy passenger vehicles reached 62.
5%, of which L2 still accounted for a large proportion.
Lu Fang, chief executive of Lantu Automobile, said earlier at the Summer Davos Forum in June that “L2-level auxiliary driving is expected to be widely available within three to five years.
” It can be seen that for a long time in the future, L2 and L2 + vehicles will still be the main body of the market.
Therefore, it is called on the relevant national departments to fully take into account the actual market situation when formulating relevant standards, and bring the auxiliary driving system sign lights into the category of national compulsory standards, at the same time, unify the number, color, position and priority of sign lights, in order to improve road driving safety.
In addition, the Ministry of Industry and Information Technology is also called on the Ministry of Industry and Information Technology to include sign lights equipped with auxiliary driving system as a condition for new car access in the “measures for the Management of Road Motor vehicle production Enterprises and Product access permits”.
As one of the safety inspection items that must be passed before the vehicle is put on the market.
The positive significance behind the sign lights of the auxiliary driving system, as one of the safety configuration of the vehicle, the introduction of the sign lights of the auxiliary driving system can promote the overall standardized development of the auxiliary driving technology through the formulation of a series of technical specifications and standards.
For example, through the design of the color and flashing mode of the sign lights, we can further distinguish different levels of auxiliary driving systems, such as L2, L3 and so on, so as to accelerate the popularization of auxiliary driving systems.
For consumers, the popularity of auxiliary driving system signs will enhance the transparency of the entire intelligent Internet connection automobile industry, so that consumers can directly understand which vehicles are equipped with auxiliary driving systems, enhance their awareness and understanding of the assisted driving system, and enhance trust and acceptance.
For car companies, the auxiliary driving system sign light is undoubtedly an intuitive embodiment of product leadership, for example, when consumers see a vehicle equipped with auxiliary driving system sign lights, it will naturally be associated with high-tech, safety and other positive image, so as to increase the willingness to buy.
In addition, from the macro level, with the global development of intelligent network automobile technology, international technical exchanges and cooperation are becoming more and more frequent.
Judging from the current situation, countries around the world do not have clear regulations and unified standards for the sign lights of the auxiliary driving system.
As an important participant in the field of intelligent network automobile technology, China can lead and promote the standardization process of auxiliary driving technology around the world by taking the lead in formulating strict auxiliary driving system sign light standards.
it will help to further enhance China’s position in the international standardization system.
Conclusion: it looks like a small auxiliary driving system sign light, but the influence behind it is not to be underestimated.
It is not only related to the safety and order of road traffic, but also plays a vital role in promoting the benign development of auxiliary driving and even autopilot technology.
It is believed that with the continuous improvement of relevant regulations and standards, the sign lights of the auxiliary driving system can be fully popularized and applied, laying a solid foundation for building a more intelligent and safe urban intelligent transportation in the future.
