Understand that Chedi released the automobile active safety testing system： covering 16 scenarios in 3 dimensions.

On July 20th, 2024, Chedi Summer Test was closed. The data shows that China brand new energy vehicles keep ahead in all test results in this summer’s test. In terms of battery life, the overall battery life achievement rate of pure electric vehicles increased by 5% compared with 2023, and all group test champions were won by China brand; In terms of active safety, there are 7 models with the highest test speed of 80km/h in rainy night, all of which are China brand models; In terms of intelligent cockpit, the 17 models with voice interaction scores exceeding the average are all China brand models.

At the closing ceremony, Know Car Emperor officially released the automobile active safety testing system. Relying on the test site, the future active safety measurement of Knowing Car Emperor will cover 16 test scenarios in three dimensions, including forward active safety, backward active safety and extreme weather scenarios, and evaluate the active safety performance of vehicles in a multi-dimensional and complex traffic environment in 360 degrees without dead ends. In 2024, there will be more than 100 vehicles that know the active safety of Chedi.

According to reports, in 2024, it was more open and transparent to understand the test standards jointly built by Chedi Summer Test and car companies. More than 50 car company technicians and industry experts from 20 brands participated in or observed the whole test process on the spot to witness the progress of China’s new energy vehicle industry. Xu Haidong, deputy chief engineer of China Automobile Industry Association, said: "The summer test of knowing the car emperor in 2024 reflects the global leadership of China’s new energy vehicles in terms of battery life and intelligent network connection, and shows the whole industrial chain layout of China automobile enterprises. China will eventually give birth to top automobile manufacturing enterprises."

China brand has performed well, and its active safety performance has improved significantly.

In 2024, the summer test of knowing the car was held in Wuhan, and the parallel environment of high temperature and heavy rain was closer to the actual car use scene of users in summer. At the same time, relying on the professional test site Wuhan Intelligent Networked Automobile Test Site, it provides users with more professional and practical reference.

In the actual test, China brand new energy vehicles performed well as a whole. In terms of endurance energy consumption, the average endurance of pure electric vehicles participating in the test is about 500 kilometers, and the average endurance achievement rate is about 70%. Users have basically bid farewell to endurance and mileage anxiety. All the group test champions were won by China brand, among which Wenjie M9 and Deep Blue S7 won the championship of pure battery life and fuel consumption without electricity for extended range/plug-in hybrid vehicles respectively. Xiaomi SU7 won the first place in the cruising range and endurance achievement rate of pure electric cars; Haobo HT and Jiyue 01 won the first place in the cruising range and endurance achievement rate of pure electric SUV/MPV respectively.

Active safety is another key content of this summer test. In the subject design, Zhiche Di and Central South University released the "Road Traffic Accident Scenario Analysis Report for Autopilot Testing", which screened out typical scenarios prone to traffic accidents from professional data and real cases. In this summer test, the car-knowing emperor tested the forward and backward scenes. The test results show that compared with the summer test in 2023, the overall improvement of China brand in active safety is obvious. However, in the face of complex environment, there is still room for improvement in the vehicle’s active safety capability. When driving, we should not take it lightly because the vehicle has active safety configuration.

In the forward scene of "encountering a faulty car on a rainy night", only 16 of all 35 test cars passed the test at the minimum speed of 60km/h, and the passing rate was less than 50%. Seven models, such as Wujie M7, Weilai ET5, Aouita 12, Zhijie S7, Wenjie M9, Tucki G6 and Tengshi N7, passed the test with a top speed of 80 km/h. From the million-dollar level to the 100,000-dollar level, Baojun Yunyun showed excellent intelligent driving ability in the test. The backward test simulates the scene of "reversing children crossing". Compared with the forward scene, only 6 out of 35 cars passed the test, with a passing rate of only 17.14%. The backward active safety capability of new energy vehicles needs to be improved due to the imperfect white list database of backward active safety targets and limited recognition ability of sensing hardware.

Another highlight of this summer test is that Ma Qinghua, the champion driver of WTCR, was invited as a tester to test the lap speed of all vehicles and test their ultimate performance. In the end, Zhiji L6 won all the test vehicle championships with a lap time of 2 minutes and 15.06 seconds, while Lectra 08 EM-P won the SUV championship with a lap time of 2 minutes and 19.87 seconds. In addition, in the summer test, subjects such as wetland braking, intelligent cockpit and vehicle privacy were tested, and the vehicle handling, safety and use experience were comprehensively investigated.

Public live broadcast, car enterprise supervision, and create a weather vane for China automobile evaluation.

Up to now, Knowing Car Emperor has accumulated nearly 3,500 test models, which is the first car content platform in the industry to build a full-scale and systematic test at room temperature and extreme environment, and can provide users with the most comprehensive, real and professional car product evaluation in the industry. Compared with previous tests, all the core subjects of the 2024 Chezhidi Summer Test were broadcast live, and all the test vehicles were purchased by Chezhidi at his own expense to ensure that the test process was open and fair.

In order to make the test standard more credible, Chedi has invited car companies, third-party experts and users to participate in this summer test. Before the official start of the summer test, we had a full discussion with the heads of R&D, engineering and testing teams from 20 automobile brands on the whole details of the summer test subjects, standards, equipment and processes. During the summer test, more than 50 technicians from automobile enterprises visited the site and directly participated in the test or observed it on the spot. After the official test, some car companies brought their own vehicles to conduct repeated tests on the spot to quickly improve their products.

Wang Ruoran, the person in charge of the original test of Chedi, said that "openness" has brought more challenges to the summer test, but it has also made the test more diverse in perspective and richer in content. Knowing Chedi’s summer test can stand the scrutiny of all parties with a magnifying glass. Testing is not to find "standard answers", but to work together to create value for users.

Professor Tsinghua University Song Jian, who watched Chedi’s summer test in 2024, said: "Chedi conducted the test based on a comprehensive and in-depth understanding of the principle, structure and use of the car. The test method was advanced, the test equipment was excellent, and the test site was professional. After long-term and patient experiments, objective and practical test data were obtained. It can play an important role for consumers to purchase vehicles and the healthy development of the automobile industry. " As a professional stage for China’s new energy vehicles to show their strength, knowing how to test cars in summer has become a weather vane in the industry.

The vehicle active safety testing system was released, covering 16 scenarios in 3 categories.

At the closing ceremony, Know Car Emperor officially released the automobile active safety testing system. The system will cover 16 test scenarios in three categories: forward active safety, backward active safety and extreme weather, and evaluate the active safety performance of vehicles in a multi-dimensional and complex traffic environment in 360 degrees without dead ends.

According to reports, safety is one of the topics that users are most concerned about when buying a car. The "Insight Report on New Energy Vehicle Consumption" released by Chedi and China Automobile Association shows that safety is one of the three most concerned factors for new energy vehicle users when buying a car. The data also shows that in the past two years, the number of visits to the measured data of active safety of Chedi increased by 117% year-on-year, and the number of active safety searches increased by 54%.

Since 2019, Chedi has taken the lead in the industry to start active safety measurement and continuously upgrade the testing system. From 2019 to 2020, Chezhidi explored the earliest active safety testing system in China with reference to the E-NCAP standard, and carried out four tests on 146 vehicles, including AEB rear-end static fake vehicle, AEB children’s ghost probe, vehicle-to-vehicle dynamics and children’s pedestrian crossing. From 2021 to 2023, there will be 201 test models and 10 test subjects for the active safety measurement system of Chedi.

In 2024, Zhiche Di’s active safety test will be fully upgraded in terms of test scenarios, test sites and test tools. It is estimated that the number of active safety measured vehicles will reach more than 100, covering all popular new energy vehicles. Relying on the professional test site, I know that Chedi will simulate various working conditions such as expressway, urban road and rain and fog environment in the test; And relying on the DEMatrix high-precision vehicle driving state analysis system that understands the original research of Che Di, the collision speed can be accurately judged in real time. Make the test process more professional and the test conclusion more accurate.

Wang Ruoran said that in 2024, the car emperor planned to test 450 models, covering 100% of popular new cars; At the same time, new cross-country and track measurement lists were added; The test content will be expanded to 7 dimensions and 40 subjects. In the future, Know Car Emperor will continue to invest in safety testing to provide more comprehensive and professional vehicle safety reference for automobile users.
