On the last day of this year's National Day holiday, a new M5 car with the intelligent driving function turned on when it drove to a bend of Binhe Expressway, it hit and killed 11 sheep who accidentally crossed the overtaking lane without emergency braking, and then hit the guardrail and continued to drive forward for more than 100 meters. Finally, the owner was able to stop by pressing on the brakes.

In the face of the owner's doubts, Mr. Lu, the dealer said that the vehicle had detected an obstacle, the speed of the vehicle had been reduced from 106 yards to 98 yards, and the automatic emergency braking had limitations for the shorter obstacles ahead.
The AITO user care center said that it attaches great importance to the problems of users and has expedited the handling department.
Car owner: The intelligent driving function did not brake urgently and killed 11 sheep
"When I bought this car, I liked the intelligent driving function." Mr. Lu said that the new M5 extended range MAX car was purchased at the end of August this year, and the configuration plus the intelligent driving function cost a total of about 270,000 yuan.
Before the incident, Mr. Lu had been using the intelligent driving system, and when the vehicle drove to a place with a large turn, it did not slow down significantly, but crashed straight into a flock of sheep in the overtaking lane, and then crashed into the guardrail on the side of the road. Eleven sheep were killed in the accident. "I quickly stepped on the brakes and pulled the steering wheel before I braked the car to a stop." Mr. Lu said.
After the incident, Huawei's backend detected that the vehicle had suffered a traffic accident, and a staff member called to inquire, and then Mr. Lu contacted the insurance company and called the police. "I've seen the monitoring on the highway and the brake lights haven't come on, and the ABS system hasn't worked. The insurance company could have come and tow the car, but Huawei said they would."
Mr. Lu told The Paper that the shepherd could not be found at that time, and the traffic police ruled that he should bear full responsibility, saying that the insurance company could pay later.
The road traffic accident identification made by the Dali Expressway Traffic Police Brigade of the Traffic Police Detachment of the Dali Prefecture Public Security Bureau states: At 11:52 on October 7, Mr. Lu drove a small new energy vehicle in the direction of Binchuan at 61 kilometers and 480 meters of Binhe Expressway in Heqing County, Dali Prefecture, Yunnan Province. The driver, Mr. Lui, was injured; The party, Mr. Lui, is fully responsible.

In the evening of the same day, Mr. Lu felt a lot of pain in his neck and back, so he went to the hospital for a CT scan and MRI. According to the outpatient medical records of the First People's Hospital of Yunnan Province, after a number of examinations, Mr. Lu was preliminarily diagnosed with multiple injuries to his body, including his neck and chest, and the hospital recommended that relevant auxiliary examinations be improved, such as symptomatic treatment for hemostasis, dehydration, pain relief, and hospitalization for observation.
Dealer: The vehicle has detected an obstacle and its speed has dropped from 106 yards to 98 yards
Kunming Hengwei Automobile Sales & Service Co., Ltd. is the dealer of this car. At first, the company's staff suggested that after the vehicle was repaired, according to Yunnan customs, a piece of red cloth could be hung on Mr. Lu's rearview mirror, and the matter would be settled.
The staff of the above-mentioned company told The Paper that Mr. Lu found that the distance from the sheep to the car should be about 110 meters to 120 meters, but he did not take the initiative to step on the brakes or adjust the direction, according to the speed at that time, the car traveled an average of more than 30 meters per second on the highway. questioned whether Mr. Lu had a problem with fatigue driving, "Under normal circumstances, when I use the driver assistance function, I will definitely take the initiative to slow down or brake when I find an emergency in front of me, but he doesn't notice it." Driver assistance functions are not the same as autonomous driving, and the driver should always keep an eye on the front and take over and deal with any unexpected situation immediately. ”
The police arrived at the scene to deal with it.
According to the official website of the new M5, the car is equipped with 1 lidar, 3 millimeter-wave radars, 11 lateral and forward-facing visual perception high-definition cameras, and 12 ultrasonic radar fusion perception systems. "The omnidirectional anti-collision system composed of forward, sideways and backward active safety supports a variety of road conditions, automatic emergency braking, active deviation correction and risk avoidance, making driving safer."
"In just four seconds after seeing the sheep and crashing, the car had detected a possible obstacle in front of it, and the speed of the car had dropped from 106 yards to 98 yards." The above-mentioned staff told The Paper that Mr. Lu braked only 5 seconds after hitting the sheep. In the official test, the normal braking distance needs to be 35 meters when braking down at a speed of 100 kilometers per hour, not to mention his short braking distance.
"From radar detection to automatic emergency braking 'AEB', there are limitations in the middle of the journey, such as poor weather conditions, radar or camera areas are blocked, and it can lead to inaccurate data." The staff member cited that there are short things in front of them, such as small animals or children, which belong to the blind spot of the radar, including the target in front of them is in a turn, and if this thing is short or an animal, the radar may not be able to detect it, and Mr. Lu's situation is in line with the latter.
The application for a four-year warranty extension was rejected by the owner
Immediately after the vehicle was involved in the accident, they got in touch with Mr. Lui to ask if anyone had been injured or needed on-site assistance. Mr Lui responded that he had suffered some minor injuries but that he was fine. Subsequently, the company arranged for a tow truck to transport the vehicle from Dali to Kunming. The next day, the vehicle arrived at the store, and on October 9, a staff member was sent to visit the hospital.
According to the above-mentioned staff, the vehicle was repaired through insurance in accordance with the normal process, and was handed over to Mr. Lu after the test drive confirmed that there were no problems. Maybe Mr. Lu felt that the company was not sincere, and they applied for an extension of the warranty, which originally had a warranty of 100,000 kilometers for four years, and extended it to 160,000 kilometers for eight years.
"I can't continue to drive this car because it's likely to endanger my life on the next drive." As for the solution proposed by the car company, Mr. Lu clearly rejected it.
In his opinion, the crash could have been avoided if the vehicle's intelligent driving system had automatically slowed down when cornering and had been able to activate the emergency braking function immediately when it encountered a flock of sheep in front of it. However, after hitting the sheep and the guardrail, the car did not automatically slow down and stop, but continued to drive forward, and finally relied entirely on manual foot brakes to stop, which is completely different from the previous publicity of the car company.
Based on this situation, Mr. Lui suspected that there might be a problem with the car's emergency braking system, and he demanded that the dealer either refund the purchase price of the car in full or replace it with a brand new model of the same model, and compensate him for the mental distress and lost work he suffered as a result.
Regarding Mr. Lu's request, the above-mentioned staff said that according to the current process, it is basically impossible to achieve, "reasonable demands, the store will try its best to fight, but if the owner's requirements are too high, we really can't do anything." ”
AITO Customer Care Center: The department has been expedited to deal with it
On October 13, the customer service staff of the AITO User Care Center told The Paper that they attach great importance to the user's problems and have immediately urged the user's situation and demands to the processing department, and need to wait patiently.
Is it difficult for vehicle radar to detect low animals? The customer service staff of the AITO user care center explained that at present, when encountering but not limited to the following scenarios, the system may miss detection, false detection, and failure to detect obstacles in time due to various factors such as front occlusion or the type of target ahead, location, and occurrence time, resulting in the system not warning and braking or not warning and braking in time; Poor weather conditions, such as rain, snow and fog, etc., where there is a large vehicle in front of the vehicle blocking a detection area of the vehicle's radar or camera; There is an obstruction or obstacle in front of the vehicle, and the light ratio contrast with the front sight environment is not strong, resulting in unclear, inaccurate and incomplete obstacle identification; There are pedestrians/two-wheelers carrying large objects in front of the vehicle, and pedestrians/two-wheelers in front of the vehicle moving slowly into the lane or running in the opposite direction towards the vehicle; The self-vehicle or the target in front of it is in a curve, and there is a target in front of the self-vehicle that can only be detected after the self-vehicle changes lanes, and other scenarios beyond the inspection conditions and scope of the self-vehicle radar or camera.
When a vehicle hits an obstacle, does it trigger AEB for emergency braking? The customer service staff of the AITO user care center said that AEB is a driving assistance function, which is not designed to avoid collisions, but can only minimize the degree of collision by trying to reduce the driving speed, and the degree of reduction of vehicle speed or the degree of frontal collision of the vehicle when braking will be affected by many factors such as the speed of the vehicle, the distance between the obstacle type and the obstacle, the driving environment, and the delay in system response.
High-speed maintenance unit: the uneven road section of the incident cannot be installed with welded mesh
On October 12, the staff of the Binhe Expressway Management Unit explained to The Paper that local villagers are generally used to raising sheep on a free-range basis. Due to the uneven terrain of the road where the incident occurred, it was impossible to install welded mesh, and although all the isolation nets have been set up around the high-speed land, there are still some gaps, so that the sheep can cross and then go up to the high-speed road.
In the dash cam, the sheep appear in the passing lane.
The staff of the custody unit also mentioned that villagers sometimes choose to cross the highway in order to collect fungi or herd sheep, and even do not hesitate to destroy the isolation net. In order to solve this problem, the custody unit, local government, police station, road administration, traffic police and other departments have gone deep into the village to carry out publicity and education work, requiring villagers to stay away from the highway when grazing livestock.
"We have issued a notice to the construction unit asking them to carry out a second or even third reinforcement work. At present, two quarantine measures have been completed in some areas. In addition to this, they have also set up warning signs in specific areas to explicitly prohibit villagers from destroying the quarantine facilities, according to the staff of the custodial unit. At the same time, the highway department has recently asked the management and maintenance unit to conduct a comprehensive investigation again, and will conduct a review and inspection.
