Driver Fatigue Detection System Explained
As the automotive industry continues to evolve, innovation and safety remain at the forefront of technological advancements. One such innovation is the driver fatigue detection system, a technology designed to prevent accidents caused by drowsy driving. Driver fatigue is a serious issue affecting millions worldwide, leading to road fatalities. The system can detect even the slightest signs of driver fatigue and alert the driver timely. Let’s learn more about the driver fatigue detection system in detail.
What is Driver Fatigue Detection System?
The dangers of drowsy driving cannot go unnoticed. It is widely known that drowsy drivers are a significant hazard to everyone on the road. Many technologies and programmes are aimed at making driving safer and reducing the likelihood of catastrophic road accidents caused by human error.
However, to combat driver drowsiness, automotive experts developed the driver fatigue detection system. Most advanced driver assistance systems (ADAS) come with a driver fatigue monitoring system. Such modern car safety feature detects drowsiness timely to avoid accidents caused by microsleep, tiredness, and inattentiveness.
How Does Driver Fatigue Detection Work?
The driver fatigue detection system is an innovative solution that uses advanced types of car sensors and cameras to detect early signs of driver fatigue by keeping a check on eye movements, head posture, and facial expressions.
Once the system detects that the driver’s motions are unpredictable and that they don’t appear aware, it starts to consider other factors as well. For instance, the drowsiness detector may examine the vehicle’s speed, the time of day, the weather, and other factors.
Following this, it can determine drowsy driving by calculating the driver’s tiredness index and start to act, such as alerting the driver through visual or audible warnings. It may even alert the driver through a vibrating steering wheel or even a vibrating driver’s seat.
It should be kept in mind that the driver fatigue management system only alerts the driver to take a break and not to keep them awake on lengthy journeys. After the warning, the driver should find a place to pull over and rest for some time.
Which Sleep Detection System Does My Car Have?
Usually, every new car model comes packed with a bundle of advanced features and technologies. Systems that track driver attention are referred to as ‘driver fatigue detection systems’ in general.
However, some automakers combine sleep-detection systems in cars with other features and give them distinctive titles. But the majority of features have self-explanatory names, such as driver attention alert, sleep detection, fatigue monitoring, and more.
Mercedes-Benz’s Attention Assist
This system uses a combination of sensors to analyse driving behaviour and assesses the driving techniques over 70 parameters. It considers external factors as well including crosswinds, road conditions and interactions with car controls.
If the system detects signs of fatigue, it will alert the driver by activating the coffee cup warning light on the dashboard, prompting the driver to take a break.
Land Rover’s Driver Condition Monitor
Land Rover’s Driver Condition Monitor is a feature of the Land Rover In-Control system. It can tell if the driver is getting sleepy and alerts them to stop driving and take a break.
Volvo’s Driver Alert Control
The Driver Alert Control identifies gradually declining driving ability. When the speed is greater than 65 km/h, the function is engaged, and it remains active as long as the speed is greater than 60 km/h.
The driver is informed by a ‘coffee cup’ indicator on the dashboard, an audible indication, and the text message ‘Time for a break Driver Alert’ if their driving becomes particularly erratic.
BMW’s Driver Alertness Monitoring
This system uses a camera to track the driver’s eye movements and detect signs of fatigue or drowsiness. If the system detects the driver becoming drowsy, it will alert the driver with an audible warning.
Audi’s Active Lane Assist
Audi’s Active Lane Assist uses a camera to monitor the driver’s position within the lane and detect changes in behaviour, such as swerving or drifting. If the system detects signs of drowsiness, it will alert the driver with audible and visual warnings.
Ford’s Driver Alert System
The Driver Alert System is part of the Ford Co-Pilot 360 suite. notices changes in the driving pattern and alerts the driver through the instrument cluster accordingly. The warning system works in two steps:
- The system first sends a temporary warning to the driver to take a break. This notice is only displayed briefly.
- The system then issues another warning that stays on the instrument cluster for a longer time if it notices a further decline in driving attention.
To dismiss the warning, simply push the ‘OK’ button on the steering wheel control.
This was all about the driver fatigue detection system. The algorithms used by such systems are highly advanced and can detect even subtle changes in the driver’s behaviour. Apart from the driver fatigue warning systems, there are certain gadgets that work as drowsy driver alert systems which are incorporated in headsets, headbands and eyewear as well. That said, as technology continues to evolve, it can be expected to see more advanced systems designed to improve driver safety on the road.
