A model based filtering technique for driver's heart rate monitoring using seat-embedded vibration sensors

In this paper we consider the driver's heart rate monitoring problem for safety driving. To detect the heart rate of the driver, we adopt seat-embedded piezoelectric sensors. This sensor measures the body vibration caused by the heart beat but the signal also contains the large amount of car body vibration according to the road conditions. For this problem, we propose a heart rate detection system based on the ARX model based filtering technique.
