What does dms mean? Attachment: Detailed explanation of DMS system

php Xiaobian Yuzai will introduce to you the meaning and detailed explanation of the DMS system. DMS, Dealer Management System, translated as dealer management system, is a software system specially designed for automobile dealers. It achieves comprehensive management and control of dealer business by integrating various business modules, such as inventory management, sales management, customer relationship management, etc. The role of the DMS system is to improve the operational efficiency and management level of dealers and help dealers better manage various aspects such as car sales and after-sales services. In this article, we will explain the functions and advantages of the DMS system in detail to help readers better understand and apply the system.

The eyes are too small to open Xiaopeng?

Recently, a topic "The car owner was mistakenly judged as sleeping while driving by the autonomous driving due to his small eyes" topped the hot search on a social platform. The cause of the incident was that a car blogger @DerekTLM posted a post on the social platform and addressed Xiaopeng Motors CEO He Xiaopeng, saying, "I really just have small eyes and didn't fall asleep while driving! If you don't optimize this problem, then small eyes are not worthy of it." Use NGP?"

It turned out that he used Xpeng's assisted driving function when driving a Xpeng car. Because his eyes were small, the system misjudged him as sleeping while driving, resulting in deductions for his intelligence driving points. Car blogger Chang Yan also encountered a similar situation. The Xpeng P7 he purchased would prompt him to sleep, and Lantu FREE would turn on the cold air in winter to prevent fatigue driving. The ET7 he recently purchased also frequently prompts him to feel tired and distracted, which bothers him.

Why is there a miscarriage of justice?

DMS is responsible for this. The full name of DMS is Driver Monitor System. Let’s look at the picture above. This is the driver’s perspective of a Xiaopeng P7. The small light on the steering wheel is used to illuminate the driver’s face. The red box below is a camera that monitors facial, body, and eye movements; there are also other lights inside the steering wheel. There are torque sensors that monitor your hand movements; they form a DMS that can remind you to concentrate on driving when your mind wanders.

Why does DMS identify small eyes as being distracted? There is a high probability that the proportion of visual recognition is too high. At present, vehicle-mounted DMS is still in its early stages. The mainstream perception solution is based on visual perception. The basis for DMS judgment may only be superficially based on the above-mentioned eye closure size, eyeball movements, and hand movements. etc., so misjudgments are prone to occur.

At the end of last year, Xpeng Motors launched the “Intelligent Driving Score” function on the APP. Simply put, the system will calculate the driving score based on driving It scores the driver's driving behavior, which has the effect of supervising driving, improving driving safety and driver's safety awareness. This small-eyed car owner raised questions because his smart driving points were mistakenly deducted.

Corner case from a group with small eyes

I immediately followed up, very quickly, 7 On the afternoon of March 26, He Xiaopeng contacted Liu Yilin, deputy general manager of Xiaopeng's Internet Center. Both Liu Yilin and the official Weibo responded that relevant personnel of autonomous driving products had received optimization requirements overnight and would actively optimize immediately. Although there may not be many people with small eyes, when assisted driving is turned on, misjudgments by the DMS still have an impact on driving safety. After receiving special needs, we immediately started an optimization project for such a group. Simply speaking, this attitude is quite "new force".

The importance of DMS

In the future, with advanced deep learning algorithms, 3D imaging, optical lenses, With the technological development of infrared cameras and even various sensors placed on seats, DMS will be even smarter. Let me make a loose analogy: if autonomous driving is the perception of the outside of the car, then DMS is the perception of the driver inside the car. Today, DMS technology is still stuck in a pure visual solution similar to Tesla, and has not yet developed to Multimodal perception.

We all remember that when we were learning to drive in a driving school, the instructor always sat next to you and stared at you. This is "everyone drives together." When there is no instructor around and you need safer and easier driving, " "Human-machine co-driving" is a function that provides timely help for technological development. As of May 21, the cumulative mileage of Xpeng Motors NGP users reached 5,019,689km. With the increase in the use of assisted driving, He Xiaopeng said this at the 2022 China Electric Vehicles 100 Forum: "The second half of intelligent driving will soon arrive, and starting from 2023, it will enter the era of "human-machine co-driving"."

Before we really let go of our hands on the steering wheel and let the car drive, we will still be in a state of human-machine co-driving for a long time. DMS plays an important role in human-machine co-driving. So far, many car companies have not paid attention to this area. Maybe this seemingly funny little incident will become a milestone that prompts Xiaopeng to start paying attention to DMS research and development.

Okay, that’s it for today. I hope it can help you to a certain extent. After carefully reading this article about what dms means "Attachment: Detailed explanation of DMS system", I feel that I have learned a lot. Help share.
