What is a Driver monitoring system?

by Fms International Fleet Management Solutions

A driver monitoring system is a real-time system that collects observable information about drivers and tests their ability to perform dynamic driving tasks safely.

 

In the literature, several methods for driving monitoring have been discussed. Among them, sensor-based and non-contact (such as camera-based driving monitoring systems) are the best choices.

 

However, camera-based solutions, which use physiological signals, outperform sensor-based solutions due to their contactless application. Also, they are not expensive to use in real life.

Therefore, using camera-based surveillance to assess attention seems to be an appropriate approach.

 

It can detect if the driver is alert, monitoring the road, distracted, or preoccupied with dynamic driving tasks. Its functions may also include monitoring the use of driving controls, infotainment system use, and face tracking to assess driver gaze and drowsiness.

The driver's state is mainly estimated by eye statistics, blinking, gaze direction, yawning, and head rotation.

 

How does distracted or drowsy driving occur?

 

The driver monitoring system is specifically designed to check for both states - drowsiness and distraction.

 

Distraction

 

Several factors can lead to driver distraction. When distracted, they lose focus on dynamic driving tasks, resulting in a higher risk of collision.

 

Distraction can be divided into three categories: visual distraction, auditory distraction, and mechanical distraction.

 

Visual distraction is associated with staying away from the road. Gaze and eye statistics are widely used to detect distracted drivers, as they are a simple and effective way to check if the driver is looking at the road.

 

Auditory distraction involves responding to an incoming telephone ring.

 

Mechanical distraction is related to the driver's body posture during dynamic driving tasks. Head orientation was also used to determine their level of distraction. So some Distraction monitoring system helps reduce accidents due to driver fatigue and distraction

 

Drowsiness

 

According to the National Sleep Foundation, almost half of American adult drivers admit to feeling drowsy while driving. Additionally, more than 40% of drivers admit to having happened at least once in their driving career.

 

The data shows how common drowsy driving is.

 

Every day, these drivers put themselves at risk. Drowsiness can be detected in drivers when they lack the motivation to engage in dynamic driving tasks and instead seek comfort at rest.

 

Drowsy driving is similar to drunk driving, according to the National Safety Council. If the driver is fatigued, the chances of a crash are tripled.

 

Why should one use a DMS?

 

To develop an efficient driver condition monitoring system, every aspect of a human being must be analyzed, from his/her race, facial hair, glasses, and more!

 

It must have been a tedious task, but the results of this analysis provided surprising results and helped save lives.

 

Think, for example:

 

After a tiring day at work and a little sleepy, the driver attention monitoring system will check your eye stats and remind you to take a break and have a cup of coffee!

 

From the speakers, you will play music and have fun with your family. Suddenly, you turn to talk to your child, and the DMS detects your head movements and body patterns to signal you to focus on driving. Its handwheel function ensures that you actively control the drive. It's better to be safe than sorry, right?

 

With these points in mind, we've been hard at work developing our driver monitoring system that provides reliable drowsiness and inattention detection with just one low-powered camera in the car!

 

The Future

 

Driver monitoring systems have become an integral part of all vehicle designs. This is an opportunity to go further than others. It can lead to higher levels of security, which in turn lead to bigger sales.
