Smartphones, smart tablets, smart TVs, smart glasses…almost everything that can be used in our daily life now has smart attributes. Smart social interaction, smart home, smart wearables, smart shopping, smart office, and smart travel, the six major intelligences are making up our smart life. Little did we know that the scenes that appeared in movies in the past are gradually being realized.
What is the hottest topic in smart life right now? I am afraid that smart cars are at the top of the list, as they are the most technically difficult and require a very high investment. With the State Council officially announcing "Made in China 2025", the development of smart cars has become even more important.
In Made in China 2025, smart cars and the development of automobile intelligence have given clearer requirements and set a benchmark. Two goals are mentioned in it. One is to master the overall technology and key technologies of intelligent assisted driving by 2020, and initially establish an independent R&D system and production supporting system for intelligent networked cars; the other is to make progress in assisted driving and simultaneously establish an independent R&D system for smart cars.
After years of development, smart car technology has been continuously innovated, and many of the cars we see on the road every day already support L2 level smart assisted driving. During the Smart Expo in August this year, the three major events of the 2019 i-VISTA "China Telecom 5G Cup" autonomous driving car challenge, urban traffic scenarios, innovative applications, and commercialization progress, are more challenges to the future L3~L4 high-level autonomous driving car technology.
However, having said that, ordinary consumers can now only use L2 intelligent assisted driving. This level of intelligent driving is mainly to assist the driver, which includes the five major ADAS auxiliary systems (ACC, AEB, LDW, BSD, APS).
However, the ADAS products currently sold on the market lack unified standards and vary in product performance, consumer acceptance, and adaptability to Chinese working conditions. Against this background, the China Smart Car Index was officially born.
The China Smart Car Index System evaluates smart connected cars from the perspective of consumers in a neutral, fair, professional and authoritative manner, providing consumers with better products and user experience, and bringing consumers a better new life with smart connected cars. At the same time, it guides vehicle manufacturers, system suppliers, and hardware and software suppliers to continuously improve and optimize the design of ADAS products and smart connected cars, and promote technological progress in the entire automotive industry.
The i-VISTA Intelligent Vehicle Index successfully released the framework of the intelligent connected vehicle evaluation system in May 2017, and officially released the 2018 version of the evaluation procedures and management methods in May 2018, and released a total of 25 models in three batches. Then, on the eve of the Chongqing International Auto Show in June this year, the first batch of evaluation models in 2019 was released, with a total of 30 models. After nearly two years of investigation, research, and formal testing, the i-VISTA Intelligent Vehicle Index has made steady progress and has received widespread attention and high recognition in the industry.
As technology innovates, standard thresholds will be further improved.
After nearly nine months of repeated testing, technical research, and expert review, the 2020 version of the i-VISTA China Intelligent Vehicle Index Evaluation Procedure was officially released yesterday.
The 2020 version of the evaluation procedures will be divided into four sub-indices: smart driving, smart parking, smart safety, and smart interaction. Among them, the smart driving and smart parking evaluation procedures officially launched this time will be the first L2 automatic driving assistance system evaluation procedures and will become a new benchmark for smart car testing and evaluation.
The entire regulation is still divided into two categories: intelligent driving assistance and intelligent parking assistance.
The intelligent driving assistance module includes L1 adaptive cruise control ACC, L2 traffic jam assistance TJA and highway assistance HWA systems. The intelligent driving assistance evaluation procedure is evaluated from six aspects, including single-lane longitudinal control capability, single-lane lateral control capability, single-lane longitudinal and lateral combined control capability, lane change assistance capability, related functions, and user manual. The evaluation object is upgraded to L2 driving assistance system.
The intelligent parking assistance evaluation procedure evaluates the parking capabilities of seven major scenarios, including double-boundary vehicles/parallel parking spaces with white markings, double-boundary vehicles/white markings/vertical parking spaces with square pillars, and double-boundary vehicles/diagonal parking spaces with white markings. The evaluation object is upgraded to L2 parking driving assistance systems.
Overall, the 2020 version of the new regulations has become more demanding and strict, and the difficulty has increased after adding more scenario tests.
Compared with the 2018 version of the evaluation regulations, the 2020 version of the regulations further highlights the advantages of smart cars in improving driving comfort, safety and user experience. Combining the research results of China Automotive Research Institute on China's natural driving data and China's traffic accident data, the revised and upgraded smart driving and smart parking regulations have five main highlights:
First, for the first time, a comprehensive evaluation will be conducted on the adaptive cruise control ACC, automatic emergency braking AEB, traffic jam assistance TJA, and highway automatic driving assistance HWA that provide drivers with daily driving assistance, fully covering L1~L2 automatic driving assistance functions and filling the gap in the industry.
Secondly, the intelligent driving regulations have for the first time introduced evaluation scenarios for cutting in from the front vehicle and driving from a straight road into a curve, which reflect the typical road traffic characteristics in China, and are closer to the actual daily car use environment of Chinese consumers.
Third, the intelligent driving regulations have added the evaluation of the driver status monitoring system DMS, a safety-related functional module, to further convey the safety-oriented design and development concept of smart cars to consumers and the industry.
The addition of scores for three related functions, namely head-up display, driver monitoring, and C-V2X, is an important highlight of this version of the regulations. The head-up display installation rate is higher than the driver monitoring system, and the driver monitoring system installation rate is higher than C-V2X. The test model equipped with this function is considered a plus point. Although the score of the plus point is not high, it is still very necessary.
Taking the driver monitoring system as an example, it is very easy to fall asleep when using L2 intelligent assisted driving under high-speed conditions. This is the biggest feeling I had during the test drive. With a driver monitoring system, the driver's status can be monitored at all times, including the degree of eye opening and blinking frequency. When danger is likely to occur, the system will prompt the driver to avoid danger.
Fourth, a review process for vehicle user manuals has been added, with special requirements that the manuals must clearly specify the system's scope of use, activation conditions and restrictions, driver responsibilities and other information to prevent companies from over-promoting and misleading consumers to abuse L2 functions.
Fifth, the intelligent parking regulations for the first time added the parking capacity evaluation of square pillar vertical parking spaces, added vertical parking space limiters, increased the scoring weight of white marked parking spaces, and fully covered L1~L2 automatic parking functions.
This scene is very interesting and is also very common in underground parking garages. It greatly tests the recognition accuracy of the on-board sensors. Unlike double-boundary marking parking spaces that use cameras for detection and double-boundary vehicle parking spaces that use radar and other distance sensors for detection, square column vertical parking spaces require simultaneous detection of the white lines on the ground and the square columns. If you are not careful, there is a risk of scratches. Therefore, in terms of the scoring criteria, this project is a full score of 6 points, which is one of the highest-scoring items in the smart parking project.
Summary: Compared with the 2018 version of the regulations, the 2020 version of the new regulations is not only more difficult, but also has many requirements in terms of details. For example, the requirements for the main vehicle deceleration limit and the main vehicle deceleration speed change rate limit are added to the intelligent driving assistance evaluation. Obviously, this pays more attention to the driving experience and the riding experience.
The release of the 2020 version of the new intelligent index evaluation procedures will further promote the continuous updating and improvement of new technologies for smart cars. For consumers, it means fewer pitfalls in terms of car intelligence. The China Smart Car Index will help you read the "User Manual" that you usually don't read; the China Smart Car Index will also test whether the function is a gimmick or real use fairly and impartially...
There are many benefits for consumers. At the same time, it can also guide vehicle manufacturers, system suppliers, hardware and software suppliers to continuously improve and optimize the design of ADAS products and intelligent connected vehicles, promote technological progress in the entire automotive industry, and make application contributions to promoting the realization of the national automotive industry's medium- and long-term development plan, helping China transform from a major automotive country to a powerful automotive country, and realizing the dream of a powerful intelligent connected vehicle country.
