The assisted driving system mistakenly mistook the billboard truck for a real car and braked suddenly, causing it to be rear-ended? Official customer service response

Release time:May 09, 2024 17:53 PM

Recently, an ideal car owner in Xiangyang, Hubei Province said that while driving the L9 he just purchased on the highway, the vehicle suddenly braked suddenly while driving, causing a rear-end collision. It is suspected that the assisted driving system detected a picture of a small truck on a high billboard at the time of the incident. The vehicle brakes automatically. On May 9, an upstream news reporter learned from Ideal officials that the relevant situation is currently being investigated and will respond as soon as possible. Automobile experts remind that the assisted driving system is not an autonomous driving system. The AI driving system with visual recognition still needs a long period of iterative training and testing of various scenarios before it can eventually catch up with the judgment of human drivers. Drivers should still pay attention to safety. .

Mr. Li from Xiangyang has seven or eight years of driving experience and is engaged in the second-hand car industry. In early April, he purchased an L9 at the local Lideal 4S store in Xiangyang. Mr. Li told upstream news reporters that on April 17, he went out to do errands with a few friends and turned on assisted driving on the highway. After the vehicle automatically changed lanes while driving, the vehicle suddenly stopped when passing a billboard across the road. The brakes were applied, causing a rear-end collision.

It can be seen from the driving recorder video provided by Mr. Li that when the vehicle passed a ramp that merged into the main road, it changed lanes from the right lane to the left express lane, then started to slow down from 120 kilometers per hour, and stopped at 120 kilometers per hour. The vehicle stopped under the billboard with a minivan pattern, and the entire process lasted 13 seconds.

Mr. Li introduced that an Envision SUV behind him could not avoid the collision and directly rear-ended the vehicle. The double airbags deployed. The owner suffered minor injuries to his hands and face, and the rear of his car was damaged. The traffic police determined that Mr. Li was fully responsible for the accident.

Mr. Li believes that the Ideal Assisted Driving System recognized the two pickup truck patterns on the billboard as real vehicles, which was the main reason for the accident. "After checking the background data, the 4S store master said that the cause of the accident was that the pattern was mistakenly recognized as a real car. The 4S store proposed a compensation plan of 4,000 yuan in cash."

However, Mr. Li believed that the accident was not caused by him. At that time, the new car had not yet been registered, so it directly became the accident car. He also assumed full responsibility for the accident. After calculating the damage and other expenses, he proposed a 20,000 yuan compensation, but was rejected by the 4S store. "After that, we couldn't reach an agreement, and the vehicle was never repaired. I called the local 12345 and the official Ideal customer service number, but I still haven't received a reply after such a long time."

On May 9, a reporter from Upstream News contacted the Li Auto Xiangyang Shenzhen Industrial Park Retail Center where Mr. Li purchased the vehicle, but the staff said they were not sure about the matter. The master responsible for Mr. Li’s vehicle inspection also never answered the phone. Ideal Auto The staff of the Xiangyang Automobile Sales Company also said they were not sure about the matter. Owners can ask Ideal official customer service for relevant background data.

A reporter from Upstream News called Ideal’s official customer service. The staff said that they had received relevant information before and were currently investigating the situation and would respond as soon as possible.

In the video related to the accident, some netizens questioned that the accident was caused by Mr. Li's unfamiliarity with assisted driving operations. It was not because of the car on the billboard that he stopped, but because people needed to take over the entrance and exit of the intersection, and the assisted driving system was merging when merging. He exited when he entered the ramp. The car owner did not take over or accelerator, and the car stopped. However, some netizens believe that the exit of the assisted driving system is still a problem with the Ideal Intelligent Driving System. Why is it that the car owner is blamed?

In response, Mr. Li said he ignored these comments. "My hands were always on the steering wheel. Even if the assisted driving was disabled, I did not press the brakes at that time, but the car automatically stopped. Moreover, the driver also said that the cause of the accident was system misrecognition."

Upstream news reporters noticed that according to the official account of "Kuaikan", on May 25, 2023, Mr. Shi from Ganzi, Sichuan, was driving an ideal L7 while driving normally on the road. Suddenly, the speed dropped from 80 kilometers per hour to more than 20 kilometers per hour, and then he stopped directly. . Mr. Shi said that there were no obstacles on the road at that time, only a large billboard with the Chinese sprinter Su Bingtian in a starting pose. Mr. Shi said that after contacting Ideal officials, they said that the laser radar recognized the figure preparing to start on the billboard as a real person in the middle of the road, so the emergency stop was made. Ideal after-sales customer service responded, saying that lidar has a visual perception effect. The situation of identifying a billboard when it stops depends on the vehicle environment at the time. The specific reasons require analysis and diagnosis by engineers.

According to Li Auto’s official website, L9’s ADMax smart driving uses the “BEV fusion algorithm” and uses “pure vision” for motion perception prediction, which means it relies almost exclusively on images collected by cameras for analysis. In addition, lidar and high-precision are added. Map information input as an aid.

In response to Mr. Li's experience, upstream news reporters interviewed relevant professionals, Lu Shuai, a professor and doctoral supervisor at the School of Electrical Engineering of Chongqing University, who has long been engaged in research and development in the new energy vehicle industry. He said that just like human drivers will misjudge in various rainy days, night and backlight scenarios, the current AI-assisted or autonomous driving systems for visual recognition still need a long time to iteratively train and test various scenarios before they can finally Matching the judgment of human drivers.

As an ideal car owner, Lu Shuai also confirmed that when driving on a ramp, there will be deceleration. When the curve is relatively large or the lane line is missing, the car will remind the driver to take over and exit the assisted driving system. "But I'm not sure whether the vehicle will automatically brake without assisted driving."

"But if the cause of Mr. Li's accident can be confirmed and the car on the billboard is indeed recognized as a real car, it means that the visual recognition algorithm may need to continue to iteratively train more abnormal scenes." Lu Shuai emphasized, "Even if It was a misunderstanding, but it at least ensured your safety and stopped the car.”

Lu Shuai reminded drivers that assisted driving at this stage is not truly autonomous driving and should not treat life safety as a child's play.
