An ideal L9 owner in Xiangyang, Hubei Province said
The driver assistance system is turned on at high speeds
The vehicle is moving
A pickup truck image on a billboard at a height was detected
Sudden sudden braking leads to a rear-end collision
According to the traffic police, the owner of the car bears full responsibility for the accident. The owner believes that the accident occurred due to the reason of the vehicle, and the new car that has not yet been licensed has become an accident car, and requires the manufacturer to compensate 20,000 yuan.

On May 10, the relevant person in charge of Li Auto replied to reporters that the cause of the accident was the misidentification of the picture as a real car, "it is indeed a system misidentification, and the software system will be improved in the future."
For compensation, the Li Auto 4S store proposed a cash compensation plan of 4,000 yuan, but has not yet reached an agreement with the car owner.
The damage to the vehicle involved
Liu Hao, an analyst in the automotive industry, told reporters that at present, intelligent driving technology is generally in the L2 stage, and the systems and algorithms of various brands are not mature enough to replace the driver to fully control the vehicle.
According to the national recommended standard of "Classification of Automobile Driving Automation", the L2 driving automation level is combined driving assistance, the target and event detection and response subjects are the driver and the system, and the responsible subject is still the human driver.
In this accident
Ideal L9 after turning on the assisted driving system
There are no obvious obstacles
The AEB (Emergency Braking Function) is activated suddenly
This condition is known as the "ghost brake"
The principle of AEB is through cameras, radar, etc
Sensors detect the distance of obstacles ahead in real time
The distance that will be measured
Compare with alarm distance and safety distance
If the distance is less than the safe distance
The AEB system starts and makes the car brake automatically
Liu Hao said that the ghost brake is related to the vehicle's perception system. Among the sensors, millimeter-wave radar is not good at identifying static objects, and the camera is greatly affected by the external environment. Nowadays, the vision + radar fusion scheme is commonly used, and there is an inaccurate identification.
It is understood that the ideal L9 Pro version of the model is equipped with 10 cameras, 12 ultrasonic radars and 1 millimeter-wave radar; The Ideal L9 Ultra is equipped with 11 cameras, 12 ultrasonic radars, 1 millimeter-wave radar, and 1 lidar.
This is not the first time that Li Auto has been misidentified

The emergency brake was rear-ended by a vehicle behind him
March 2023
An ideal L9 owner posted a video saying
When it worships its ancestors in the cemetery
The radar inside the vehicle showed a figure around the vehicle
But in fact, there were no pedestrians passing by outside the car

Li Auto responded that this is a defect in the visual perception algorithm, and there is a certain probability that the rearview camera will be interfered with by water droplets in a rainy night environment. At present, the algorithm research and development has added the negative sample annotation data of halo images for this kind of scene, and the algorithm is being verified internally, and it is expected that the algorithm will be updated in the next version to optimize this problem.
