This is the moment when intelligent driving "new forces" and "old scholars", "new national tide" and "hot foreign goods" are on the same stage, Tesla Model3, Weilai EC6, BYD Han EV, Xiaopeng P7, BMW ix3, and Nezha U Pro, after undergoing VARIOUS TESTS of CCRT, ushered in a focused horizontal evaluation with highlights.
On December 29, CHINA AUTOMOBILE Evaluation held the "CCRT Assisted Driving Evaluation and Analysis Meeting", which was presided over by Li Xiangrong, deputy director of China Automobile Evaluation, and Zhou Boya, director of the Technical Management Department of China Automobile Evaluation, based on the evaluation results of 6 popular models, conducted auxiliary driving evaluation and analysis for mainstream automotive media, focusing on the problems that consumers are concerned about.
As the finale event in the field of automobile evaluation in 2021, the experts of China Automobile Center have concentrated on the interpretation of the auxiliary driving performance of 6 popular smart cars on the market, and the lineup is typical and representative.
CCRT driver assistance evaluation includes performance performance (evaluation system whether it reaches the L2 level of assisted driving level) and driver interaction (evaluation system can ensure the correct use of driving), the former is divided into intelligent driving, intelligent parking and intelligent emergency risk avoidance sub-evaluation, the latter contains system prompts and driver monitoring sub-evaluation. From the perspective of indicator settings, it contains multiple elements of people, cars and environment, and covers the whole process of consumer cars. According to CCRT evaluation data, the average score rate of smart driving of the six popular models is 67.2%, and the overall performance is not good.
Some models offer optional packages of driver assistance software, and the effect of "raising points" varies from car to car.
From the sub-category, the performance performance score averaged 87.3%, and the overall driver interaction was weak, with an average of only 54.7%. Experts pointed out that this also reveals the current situation of intelligent driving functions that some car owners "can't understand and use well".
Among the performance performance, the overall performance of intelligent driving performance is better, the average scoring rate is 91.7%, and some vehicles have insufficient recognition and response to typical Chinese driving behaviors such as emergency cut avoidance of the front car, sharp deceleration of the front car, plug intrusion of the front car, slowing down of the two-wheeled vehicle, and occupation of the road by the target car.
Intelligent parking is one of the functions with high attention and obvious perception. Based on the big data of Chinese driving scenes, CHINA Automobile Center selects 6 types of large scenarios common in daily parking environment for evaluation, covering different parking space shapes, space parking spaces and different parking spaces construction methods of horizontal, vertical and oblique parking spaces.
Its inspection criteria, popularly speaking, can be summarized as 4 "no" - the identification is not accurate, the parking is not fast, the parking is not crooked, and the parking is not biased. Judging from the CCRT evaluation results, the overall level of intelligent parking of the 6 models is average, with an overall average score of 65.0%, and the intelligent parking performance advantages of some models are obvious.
Emergency avoidance is also an important assessment index of performance in CCRT assisted driving. Unexpected road construction, traffic accidents, and "ghost probes" in complex road sections often make car owners nervous. Can driver assistance systems handle it? CCRT tests showed that the 6 models performed poorly overall, with an average score of only 41.5%.
In terms of driver interaction, the driver's monitoring ability is weak. For example, some models have strong intelligent driving ability, but allow drivers to take off their hands for a long time, which has certain safety risks.
Looking at the above data, driven by market demand and scientific and technological innovation, intelligent driving technology can be rapidly commercialized, but there is still some room for improvement in actual performance.
The main "lost points" point: insufficient adaptation to the Chinese scene
According to reports, the loss of points in the auxiliary driving test, at the driving scene end, mainly occurs in the front car encounters a stationary vehicle emergency cut out, the front car is plugged at a low speed, there is an accident cone barrel on the road, the faulty vehicle is placed horizontally, and the parking scene such as parking in an oblique parking space and a narrow parking space. At the consumer end, it is manifested as unclear description of the function of the manual, incomplete early warning mechanism for hand off, unclear display of functional status and insufficient attention monitoring function.
"The crux of the matter is that they have not been fully adapted to China's road traffic scene. 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. Zhou Boya said that although the momentum of intelligent driving cars is strong, it still faces the problem of uneven product safety performance and excessive publicity of some companies, which is the focus of CCRT's driving assistance evaluation.
It is understood that CCRT is based on 1 million kilometers of traffic big data, setting evaluation items and standards around typical traffic scenarios in China. At the same time, CCRT also takes into account the driver's experience and cognitive abilities. For example, in the test of the ability to follow the car, the safety and comfort of the driver and occupants are comprehensively considered, not only the ability of the vehicle to avoid collisions is measured, but also the impact strength brought by the brakes is taken into account.
Expert Pulse Assisted Driving: Eagerly anticipated, calm use
Under the positive guidance of national policies, the acceleration of traditional car companies, and the large-scale entry of new forces and IT giants, the prospect of intelligent driving cars in China is very broad, and it is only a matter of time before they "enter the homes of ordinary people". However, various traffic accidents in intelligent driving occur from time to time, leaving some people in a wait-and-see state. In this regard, CCRT experts give eight words of advice - eagerly anticipated, calm use.
Experts believe that intelligent driving is still in the stage of assisted driving, for ordinary consumers, should adhere to the principle of prudence, moderation to choose and buy a car, which is the key to the safe use of intelligent driving system.
From consumption decisions to the entire closed loop of everyday use of cars, CCRT provides data and knowledge worth referencing. In the car selection process, "understand" the manufacturer's publicity. We see that there is a running division level publicity on the market, but from the actual test, there is a certain amount of "moisture", intelligent driving is still in the auxiliary stage, far from "automatic"; in the car purchase process, some manufacturers provide intelligent driving optional packages. CCRT verifies whether it is worth it or not through a comparative test before and after the optional installation, and the results are also different. In the car use link, we found that the intelligent performance of some models in unexpected situations did not meet consumer expectations, and even had certain safety risks. I hope that everyone will use it moderately according to the results of the model.
Since its inception, CCRT (China Automobile Consumer Research and Evaluation) has taken an independent and impartial standpoint, and has carried out testing and evaluation of automobile intelligence, electrification, occupant health, driving performance, perception quality and other dimensions from the perspective of consumers. In the future, with the further popularization of intelligent driving functions and the application of more advanced autonomous driving products, China Automobile Evaluation will also upgrade the relevant evaluation procedures, and plans to launch China's automatic driving evaluation procedures next year. At that time, CHINA AUTOMOBILE Evaluation will be in more dimensions, for people to buy and drive intelligent cars, to create an authoritative reference with the times.
