Subjective factors such as fatigued driving, distracted driving, and aggressive driving have become the leading causes of road accidents and deaths. Although global car companies are working hard towards the beautiful vision of autonomous driving, we have to admit that we are still in the stage of “human-machine co-driving”. How to help drivers drive safer, more comfortable and more convenient is precisely the driving force. The functions required by the employee safety and health monitoring system (DMS).
In the past month or two, new energy smart cars have gained enough attention. Recently, some car bloggers were judged by assisted driving as “driving to sleep” because of their small eyes, and related topics once topped the hot search. Many netizens with small eyes said that this is simply a “backstab” from technology, which is really solid!
Today, Iron and Steel would like to talk to you about this intelligent monitoring technology that can determine the driver’s driving status and its current situation that needs to be “optimized”!
There are thousands of roads, and safety is the first priority. Safety is the most basic requirement of driving, therefore, the intelligent assisted driving system is the first to have a safety monitoring system.
The driver safety and health monitoring system (DMS) is one of the components of the intelligent car assisted driving system, and you may have heard it by other names, such as fatigue/distraction warning system.
It mainly monitors the driver’s state in real time and continuously through the in-vehicle camera, such as quantifying the degree of eye opening and closing and mouth opening and closing degree of the driver, so as to judge the current driving state of the driver. Once it is found that the driver is distracted and fatigued, it will give an early warning through voice and other methods to improve driving safety.
DMS is an important part of current in-vehicle camera systems…
Intelligent monitoring to ensure driving safety
In order to cope with more real driving situations, car companies usually match infrared cameras and infrared fill lights, so that even at night, even if the owner wears sunglasses, effective monitoring can still be performed.
From a technical safety point of view, DMS is a trustworthy and necessary driving assistance function. However, in the case of “small-eyed car owners” being misjudged, it is enough to show that DMS and even intelligent assisted driving still need continuous optimization and iteration.
Aiming at the problem that DMS collects information in a relatively simple way, the automotive industry is already taking action, and car companies are trying to improve by introducing more sensors.
For example, adding a torque sensor to the steering wheel can confirm whether the driver is driving normally. Through the shared data of the wearable device, or integrating biosensors such as heart rate monitoring and eye tracking on the steering wheel, the driver’s status can be further confirmed, ensuring safety while reducing errors. sentence.
Human-machine co-driving, more convenient in the future
In addition to helping the driver maintain state in multiple directions, improving the intelligence of the car’s own monitoring is also an optimization direction.
At present, some AI algorithm companies are trying to integrate vehicle DMS with intelligent cockpit domain, intelligent driving domain and intelligent interactive functions; in order to cope with the complex driving environment, technologies such as 3D distance measurement and motion trajectory prediction are also being used by car companies and capital. focus on.
Before the family car achieves fully autonomous driving, human-machine co-driving is the current theme. New technologies such as DMS must not only ensure safety, but also ensure practicability and convenience before they are favored by consumers.
