Abstract

This paper focuses on a thorough summary of vital function measuring methods in vehicles. The focus of this paper is to summarize and compare already existing methods integrated into car seats with the implementation of inter alia capacitive electrocardiogram (cECG), mechanical motion analysis Ballistocardiography (BCG) and Seismocardiography (SCG). In addition, a comprehensive overview of other methods of vital sign monitoring, such as camera-based systems or steering wheel sensors, is also presented in this article. Furthermore, this work contains a very thorough background study on advanced signal processing methods and their potential application for the purpose of vital sign monitoring in cars, which is prone to various disturbances and artifacts occurrence that have to be eliminated.

Highlights

  • In the future, the majority of vehicles will probably be fully autonomous, so the driver will play a less significant role than today

  • The second application is based around sensory systems which monitor and regularly acquire the drivers vital signs to initiate split-second automatized decisions

  • This work mainly focuses on a thorough review of inconspicuous and contactless sensors used to monitor vital functions

Summary

Introduction

The majority of vehicles will probably be fully autonomous, so the driver will play a less significant role than today. Numerous researchers are currently working on various driver response systems, which can measure various life functions of the driver in order to monitor his/her alertness [2,6,7,8,11,12,13,14,15,16] These systems mainly detect fatigue, stress and the driver’s health condition. Advanced health monitoring systems in vehicles are, basically a necessary addition and are expected to attract further attention from insurance companies, healthcare providers or emergency services. These systems can basically react in two ways.
