The automotive manufacturers are trying to increase the number of innovative solutions for road traffic safety. However, despite the advanced technical and technological achievements the human factor represents an important role as well, such as the drivers of health status, age, decision-making ability, carelessness, threat detection capabilities. The evolution of technology makes it possible to monitor the vital physiological parameters; hence related risks could be estimated and reduced.
Researches have shown that heart rate variability (HRV) is related to current human condition. The heart rate variation is observed based on the ECG (electrocardiogram) signal.
The present study aims to develop a system, such a system that uses the ECG signal for further human behavior conclusions and transmits the measured values through the CAN (Controller Area Network) communication interface, widely used in modern cars. The implemented device is capable to send the measured signal via Bluetooth to the computer software, and allows of course to store the measured values.
