Long hours behind the wheel often lead to reduced focus and slower reaction times. This becomes one of the main causes of road accidents. To minimize the danger, cars are increasingly being equipped with special devices capable of detecting signs of driver fatigue.
These systems, known as fatigue detectors, are designed to continuously monitor the driver’s condition. They analyze a range of parameters: blink frequency, eye movements, head position, and even changes in driving style. These technologies are especially relevant for truck and bus drivers who spend many hours on the road.
The operating principle of such devices is based on the use of sensors and cameras that record even the slightest deviations from normal behavior. The system compares the collected data with preset norms and, if signs of fatigue or drowsiness are detected, it immediately triggers an alert. This is usually an audible, visual, or vibration warning aimed at refocusing the driver’s attention on the road or prompting them to take a break.
Modern fatigue detectors can operate in real time, using advanced algorithms to process information. They not only track blink rates or head nods, but also monitor sudden steering movements, changes in trajectory, and other factors that may indicate a drop in concentration.
The cost of such devices varies depending on their functionality. Basic models, limited to simple alarm signals, cost around 60–70 euros. More advanced versions equipped with cameras and facial recognition systems can range from 300 to 400 euros. For professional transport, the price can reach 600–700 euros, especially when it comes to comprehensive fleet solutions.
Installing a fatigue detector requires certain skills. It is recommended to contact specialized service centers to avoid installation errors. If the driver chooses to install the device independently, it is important to select a spot with a clear view of the face, thoroughly clean the surface, and connect the power correctly. After installation, calibration and alert settings must be configured.
The system may occasionally malfunction. Signs of failure include frequent false alarms, a lack of signals in clear cases of fatigue, error messages on the dashboard, spontaneous shutdowns, or problems with the camera and sensors. In such cases, diagnostics are recommended, and the equipment should be replaced if necessary.
The use of fatigue detectors is becoming standard in new vehicles and is a mandatory safety feature in commercial transport. These technologies help reduce the number of accidents caused by inattentiveness and make roads safer for everyone.
