Recently, an Ideal ONE in Qingdao was involved in a serious rear-end collision on the G18 Expressway. At around 22:00 on September 22, the owner of the car suddenly merged with the car in front of him on the expressway back to Qingdao, resulting in the car he was driving. The Lili ONE had no time to brake and collided with the rear of the front truck. After the accident, the entire A-pillar of Ideal was deformed. My mother, who was sitting in the passenger seat, was seriously injured and was being treated in the hospital. However, because the vehicle was in the assisted driving state of Ideal at that time, all major automotive media came to eat. Gua, as a new power company that just went public not long ago, Ideal has had a lot of accidents recently. Following a broken axle and spontaneous combustion, there was another high-speed collision with a truck in front.
The owner of the car in the accident also raised three major questions:
1. Why was it not recognized that the vehicle in front was changing lanes when assisted driving was turned on?
2. The car owner stated that the relative speed of the two vehicles at the moment of impact was about 30km/h. Why is the A-pillar of the vehicle so fragile?
3. The vehicle’s airbag did not deploy, the front windshield was shattered, and there was glass powder in the ear canals and eyes of the front passenger. What are the vehicle’s protective measures for the people inside?
At this point, Li Auto released a description of the incident through its official Weibo. The traffic control department determined that the large truck was fully responsible for the accident due to illegal merging. Although the user used the Ideal ONE assisted driving system in this accident, Li Auto later issued an official statement on Ideal assisted driving. So far, the Ideal assisted driving system has limitations in recognizing vehicles in the next lane that have entered the main lane. It cannot be identified as the main target when the vehicle in the next lane merges into 1/5 of the vehicle body.
This is also a limitation of the current L2-level assisted driving system. L2-level assisted driving still focuses on the driver. To control the vehicle, it cannot completely replace the driver in making decisions. Users are also asked to use the assisted driving system of Ideal ONE safely. ”
In this accident, because the rear of the large truck was not properly installed with a protective device that complied with national requirements and was too high, when Ideal ONE rear-ended the large truck, the A-pillar directly jammed the cargo box. The A-pillar becomes the main stress point, and the A-pillar cannot withstand such a large impact alone.
In a subsequent Weibo statement, the official also listed three models with BMW X7, Audi Q7, and Volvo XC90. Comparison of the material strength of the A-pillar materials of a luxury SUV, and said, "Although the A-pillar of the Ideal ONE uses 1500MPA ultra-high-strength steel, domestic and foreign tests and actual road traffic accidents have shown that: passenger cars are prone to drilling when they occur. In the event of a collision with a truck, if the rear protection device of the truck does not meet the standards, the A-pillar of the passenger car cannot withstand the direct collision or squeeze of the cargo box. ”
As for the situation where the airbag has not deployed, it actually depends on the scene. From the picture above, you can clearly see that the front face of the accident vehicle is almost intact, while the general impact will It hit the front part of the car first. No one expected that the car in front would collide with the A-pillar. In this regard, Li Auto also responded. In this accident, the A-pillar of the vehicle was separately squeezed, and the longitudinal beam of the front cabin of the vehicle was , the front finger beam, the anti-collision beam and the energy-absorbing box did not undergo significant deformation. This situation does not belong to the protection scenario of the airbag.
The airbag sensor cannot detect sufficient deceleration due to its limited position. As a result, the airbag did not activate, and none of the current models on sale were equipped with airbag sensors in the A-pillar. In this collision, the rear of the large truck was squeezed into the body, and even if the airbag was deployed, it would not provide any protection. " If any media friends still doubt this, they can conduct public comparison crash tests under the same working conditions with models of the same level. We are willing to provide Ideal ONE support for free. ”
I also posted a picture of the bent A-pillar of another vehicle to prove my innocence. At this point, the ideal high-speed car accident incident has come to an end. This is also a wake-up call for everyone. It has not been fully realized yet. Before fully autonomous driving, any car company's assisted driving requires manual intervention. Your own safety cannot be completely left in the hands of the machine. Just like in this incident, if the car owner has been taking over the steering wheel, this time The incident should be completely avoidable.
