Drowsiness and fatigue sensing system based on driver's physiological signals

Road accidents and casualties caused by fatigue are an important societal and economical problem for the EU. Driver fatigue countermeasures may be directed at drivers, companies, road infrastructure and vehicles. The solution developed in HARKEN project is a nonintrusive sensing system of driver's heart and respiration embedded in the seat cover and the safety belt of a car. It detects the mechanical effect of heart and respiration activity, filter and cancel the noise and artefacts expected in a moving vehicle (vibration and body movements), and calculate the relevant parameters, which are delivered in a readable format to integrate it in a fatigue detector. Redundant measures of vibrations and artefacts that may distort these signals are used to improve their quality by means of adaptive filters, programmed in a signal processing unit.
