【Pacific Automotive Network Industry Channel】A few days ago, 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, and gave users some suggestions for using the car.
The CCRT Driver Assistance Assessment includes two dimensions: performance performance (whether the evaluation system has reached the L2 level of assisted driving level) and driver interaction (whether the evaluation system can ensure the correct use of driving). The former is divided into sub-evaluations of intelligent driving, intelligent parking and intelligent emergency avoidance, and the latter contains sub-evaluations of system prompts and driver monitoring.
In addition, some models also provide optional packages of driver assistance software, and the effect of "raising points" varies from car to car, providing users with better suggestions when purchasing optional packages.
From the sub-category point of view, the performance performance score averaged 87.3%, and the overall driver interaction was weak, with an average of only 54.7%, especially the new power brand, which needed to pay more attention to the interaction ability with the driver. 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.
The intelligent parking project is based on the big data of Chinese driving scenes to select 6 types of large scenarios common in the daily parking environment for evaluation, covering different parking space shapes, space parking spaces, and different parking spaces with different parking spaces in horizontal, vertical and oblique directions. 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.
Emergency avoidance is also an important assessment index of performance in CCRT assisted driving. These include unexpected road construction, traffic accidents, and "ghost probes" in complex road sections, which often make car owners nervous. CCRT tests show that the overall performance of the 6 models is not good, with an average score of only 41.5%, of which the Tesla Model 3 score rate is 74%, while the BMW iX3, the representative of traditional car companies, has a scoring rate of only 4.2%.
The above test data shows that under the impetus of 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. In this regard, experts believe that intelligent driving is still in the stage of assisted driving, for ordinary consumers, should adhere to the principle of prudence and moderation to choose and buy cars, which is the key to the safe use of intelligent driving systems.
