Reports from The GreatAuto
Some people commented that the current intelligent driving assistance market is full of charms and demons. Every car company wants to put an intelligent gold note on its automotive products in the new era, but not every one of them has the ability to use intelligent driving assistance that is really easy to use.
Miserable and miserable, many consumers have become guinea pigs without knowing it. Looking at the news report, the front foot rider A just summoned the "seemingly safe" parking function, but there was a scratch, and the rear foot was assisted by the so-called pilot B, and an unexpected accident occurred.
Obviously, the original intention of the development of intelligent driving is to save worry and effort, but the result is that many consumers have become expensive and undesirable because of lack of awareness.
The lack of unified third-party evaluation standards, the lack of results under unified conditions, the lack of guidance and supervision of the correct use of functions, and the fact that only the car companies themselves talk about themselves in functional publicity are the most fundamental reasons for this situation.
After a few years of wild development in the market, fortunately, there is now a unified third-party evaluation standard for this problem, which is the "CCRT Assisted Driving Evaluation". It is organized by China Automobile Evaluation, and its credibility and professionalism are worthy of consumer trust. The "CCRT Assisted Driving Evaluation" is also enough to evaluate the advantages and disadvantages of the current uneven level of intelligent driving on the market.
Of course, considering that this new thing is not well understood by many consumers, we will make a brief introduction.
What is the CCRT Driver Assistance Assessment?
What are the details of its evaluation?
One sentence describes CCRT and assisted driving evaluation.
CCRT, which is the China Automobile Consumer Research and Testing Center established by the China Automobile Center, and the "CCRT Assisted Driving Evaluation" is that the center has begun to carry intelligent driving assistance for the majority of new models at present, but the market does not have a unified tripartite evaluation standard, which is difficult for consumers to quantify the gap between different models, and intuitively displays it through a unified evaluation system.
It is not only a credible, fair and objective third-party test, but also a test that can directly give consumers car purchase suggestions through data results.
Therefore, the CCRT driver assistance evaluation is designed from the beginning to be close enough to our daily car life. Not only is there 1 million kilometers of traffic big data, but also evaluation projects and standards are set around typical traffic scenarios in China.
At the same time, in order to show the details of the performance of different label functions, CCRT also fully considers the driver's experience and cognitive ability. For example, in the test of the ability to follow the car, in addition to safety, it also comprehensively considers the comfort of the driver and occupants, not only measures the ability of the vehicle to avoid collisions, but also takes into account the impact intensity brought by the system's instantaneous active braking, and this difference in physical feeling is almost avoided by car companies in the publicity link at this stage.
In terms of specific detailed design, CCRT driver assistance evaluation mainly contains two dimensions of performance performance and driver interaction, the former is to evaluate whether the system reaches the L2 level of assisted driving, including intelligent driving, intelligent parking and intelligent emergency risk avoidance sub-evaluation; while the latter driver interaction is to evaluate whether the driver can ensure that the driver is using the system correctly, including system prompts and sub-evaluation of driver monitoring. From the perspective of index settings, CCRT assisted driving evaluation includes multiple elements of people, vehicles and environment, and covers the whole process of consumer car use.
In addition, for the current market intelligent model purchase, basically are the basic configuration + optional program, for this type of driving assistance software optional package, will lead to intelligent assistance effect varies from car to car, CCRT assisted driving evaluation is also fully taken into account, will carry out the same car in different optional package configuration under the differentiated evaluation, and give a summary of the results of the comparison, for your daily purchase of a car, you need to add money to select to which extent, has full guiding significance.
After the test, experts sincerely recommend:
Eagerly anticipated, calmly used
Having said all this, whether the CCRT assisted driving assessment can detect the difference must be what you are more concerned about.
Data speaking, on December 29, China Automobile Evaluation held the "CCRT Assisted Driving Evaluation and Analysis Meeting", and the evaluation results of the first batch of 6 popular models, including Tesla Model3, WEIO EC6, BYD Han EV, Xiaopeng P7, BMW ix3, and Nezha U Pro, were released.
One word review, the test is accurate enough and fierce enough!
According to CCRT evaluation data, the average scoring rate of intelligent driving of the 6 popular models is only 67.2%, the average has just passed, and the overall performance is not good; the performance difference between different brands is significant, and even the same model, under different optional packages, there is also a qualitative difference!
For example, Tesla Model 3, for a long time, many consumers have believed that Tesla's intelligent driving is the first in the industry, and its "hugely expensive" 30,000 2 plus EAP and 60,000 4 plus FSD optional bags are worth the money.
But the test data is very "punching face", the overall scoring rate of smart driving in 6 models, Tesla Model 3 ranked second from the bottom, spent 24% more money on the car price, and after installing an FSD optional bag worth 60,000, only increased by 4.8% in the basic No-cost Autopilot score rate.
It's a bit of an "IQ tax" feeling; in contrast, the bare car is less than 160,000, and the Nezha U pro, which comes standard with intelligent driving and full-featured, is not much worse than Tesla's ability to evaluate.
This time, the surprise test of popular smart models also found more "fatal" problems.
From the data point of view, at this stage, the intelligent auxiliary driving function of smart models generally performs poorly in response to unexpected situations, such as the scenario 1 we said in the above figure, many old drivers have feelings:
When driving normally with the car, sometimes the front car will find a stationary obstacle and will quickly change lanes to cut out, and then we, as the rear car, either observe the rear car and follow the lane change, or immediately slow down or brake after observation; but for intelligent assisted driving, after the front car suddenly cuts out, the camera or millimeter wave radar will instantly lose the main following target, whether it can accurately identify the front stationary obstacle in a short period of time, and make braking or avoidance actions is a great test of algorithm and computing power.
The average scoring rate of 64.8% shows that the technology is not satisfactory at this stage.
In addition, these 6 cars in other daily scene tests, but also the performance of relatively general, especially when simulating the most deadly "ghost probe" traffic accident scene, because the speed of the car, leaving the system with a short response time, as long as there is a detail that is not done well, it is a fatal accident.
Test results, the overall performance of the 6 models is not good, the average score is only 41.5%, the average score directly failed.
In other test items, such as intelligent parking, the test results are obviously not as mythical as you see on the network publicity, in addition to a very few models performing well, the overall average score rate is only 65%, just passed the level, and once by the mythical Tesla with a score rate of 47.8%, but also confirmed what we said at the beginning, some car owners with automatic parking and summoning parking function, will also rub the reality of the vehicle next to them.
Considering that these 6 models basically represent the benchmark and head level of intelligent driving of the current mass production car, in this regard, CCRT experts have given consumers eight words of intelligent driving use suggestions - eagerly anticipating, calm use.
Of course, as we said above, the CCRT intelligent driving evaluation also includes a driver interaction evaluation, which will involve whether consumers can use the function correctly, whether the system has supervision and early warning punishment mechanisms when it is used incorrectly, etc.; and this time for the test of these 6 models, it did find many problems.
Taking the national mandatory requirements, L2 level automatic assisted driving can not be taken off as an example, only BMW won a full score, and the rest of the models scored less than ideal.
Attention monitoring is also a lot of problems, there have been reports before, there are owners in the automatic assisted driving function, thinking that the vehicle is already automatic driving, although the hands are still on the steering wheel, but closed eyes to recuperate, eventually led to the accident, and this time the "surprise inspection" found that only Weilai configured the attention monitoring function and performed well, Nezha although configured with related functions, but the monitoring effect is weak; as for other models, there is no attention monitoring ability, It is easy for car owners to have excessive trust and dependence on the intelligent driving system, which may have potential safety hazards.
So in general, in terms of the results of this CCRT intelligent driving evaluation, the test effect is very good, and it also intuitively exposes the gap and shortcomings of the majority of car companies in intelligent driving at this stage; of course, in view of the differentiated performance of different car companies in different test scenarios, Zhou Boya, director of the Technical Management Department of China Automobile Evaluation, also expressed his own views, "The crux of the problem is that they have not fully adapted to China's road traffic scenes." We recommend that manufacturers prescribe the right medicine, optimize the safety and security mechanism, and improve functional coverage. At the same time, it also continues to call on manufacturers to make accurate and detailed user guidelines. ”
Write at the end:
2021 has been regarded by many people as the first year of the intelligent development of the whole vehicle, and with technological progress and larger-scale loading and mass production, the era of universal intelligent driving will accelerate from 2022.
In this context, CHINA AUTOMOBILE Center took the lead in making due social responsibilities and launched a completely fair and impartial, objective and neutral CCRT intelligent driving evaluation, which can not only provide a unified test platform for car companies to continue to optimize technology and solve defects, but also provide enough meaningful reference materials for consumers when buying and choosing cars, which is a good test that is truly multi-faceted and beneficial.
Of course, at this stage, intelligent driving technology is changing rapidly, and we also hope that CCRT can continue to follow the forefront of technological development, constantly update and improve its own evaluation details, and bring more, better and more reference results to consumers, which will be waited for by everyone.
