This paper describes the architecture and use of a multisensor system for estimating a driver’s fatigue level. These sensors are an element of the integrated system for monitoring a driver’s behavior, also including the measurement of environmental conditions and driving technique. Sensors described in the paper are designed to work under simulated and real conditions (when driving a vehicle). To estimate the level of driver fatigue, we used a subsystem for measuring eye closing frequency and oculomotor activity (Eye Activity Monitoring Subsystem), a personal medical set and a non-contact electrocardiography signal measurement module. In addition, for comparison purposes, we used commercial solutions called faceLAB 5 (system for tracking and testing eye activity) and FlexComp (system for measuring physiological activity). The paper presents a description of the sensors, their communication with the LoggerBox master device, and their location in the car. It also presents a typical test procedure and sample signals recorded during driving.
