CTOnews.com September 19 news, NGP is Xiaopeng's auxiliary driving system Navigation Guided Pilot abbreviation, it is through the car camera, laser radar, millimeter wave radar, high-precision GPS to the environment around the vehicle to sense, so as to control the vehicle automatic driving system, this function has been open to Xiaopeng P5 and other models, but today there are reports that this function seems to have some problems.

According to China Consumer News, in April this year, Mr. Xie spent more than 230,000 yuan to buy a Xiaopeng P5 car, and paid 12,500 yuan on the day of picking up the car to buy NGP intelligent navigation assistance driving package, but surprisingly, this car repeatedly appeared in the high-speed driving state NGP automatic exit situation.

On July 4, Mr. Xie was driving his car at a speed of about 90km/h on Beijing Southeast Sixth Ring Road. The car suddenly gave an alarm,"Please take over immediately, NGP has exited," and the display screen immediately popped up prompts such as "Traffic sign recognition function unavailable,""NGP has exited,""Lane departure warning function failure,""Lane departure inhibition function failure," etc. At the same time, the speed dropped rapidly from about 90 km/h to about 50 km/h.

This is the first time that NGP has exited the vehicle. The staff of Xiaopeng 4S Store said that it may be that the three-eye camera located in front of the rearview mirror in the car is dirty, resulting in NGP function exit. But Mr. Xie raised an objection to this: the camera is sealed in the frame and people can't touch it. How can it be dirty?

Later, when Mr. Xie drove his car on Beijing's expressway, NGP automatically exited many times. Mr. Xie contacted Xiaopeng Company and 4S Store for many times, and the other party analyzed a variety of possibilities: it may be that the camera is dirty, it may also be caused by sunlight, and there may be loopholes in NGP software system. 4S Store proposes to update the software system, but there is no guarantee that the problem of NGP automatic exit can be solved after updating the system.

China Consumer News contacted Xiaopeng Company, which responded that it was "high-speed NGP withdrawal due to interference from the three-eye camera." Xiaopeng company also said, Because the vehicle driving process, Three-eye camera in a certain angle encounter strong light direct, Produce blind spot error, This situation belongs to normal optical physics phenomenon, Not camera quality problem. A staff member of Xiaopeng also said that when facing bright light, the car's three-eye camera will prompt that the line of sight is blocked, and then exit NGP. Forced withdrawal from assisted driving is to avoid drivers relying too much on assistance technology and causing misjudgment in technical amblyopia scenarios.

Mr. Xie can't accept this. He said that when the car is driving on the road, the three-eye camera located at the top of the windshield will inevitably be illuminated by strong light. If there is no sign to quit because of strong light, the auxiliary driving system will be too fragile. Moreover, in the case of dazzling sunlight, the driver's line of sight is blocked, and it is precisely when the driving assistance system needs to play a role that the design of exiting from the strong light is contrary to the actual demand.

In addition, Mr. Xie also said that before using the NGP system, car owners need to learn the NGP usage specifications and test, and only after passing the test can they use the system. However, neither the study video nor the exam mentioned that bright light exposure might cause NGP withdrawal. Mr. Xie believes that NGP withdraws without warning, causing high-speed vehicles to stall suddenly, which poses a great potential safety hazard. It is hoped that Xiaopeng Company can change its design concept and solve the problem that strong light irradiation will lead to NGP withdrawal as soon as possible.

CTOnews.com learned that recently Xiaopeng Automobile also announced that the city NGP has begun to pilot in Guangzhou and will be pushed to some Xiaopeng P5 users in the near future. From then on, Xiaopeng's assisted driving function can cover 90% of the user's travel scenarios, and the data shows that the urban NGP traffic efficiency is close to 90% of the manual navigation time.
