A Model for Identifying Fatigue Status of Vehicle Drivers Based on Driving Operation

Taking the monitoring of vehicle drivers' fatigue status as the object of study, some methods for it were introduced. An idea to establish identifying model for fatigue was presented by combining drivers' operation with their physiological indexes. Through a large number of experiments on vehicle driving simulator, parameters of driving operation and physiological indexes were collected at the same time. Then, a relation model between driving operation and physiological indexes of drivers was set up by analysis; the least square method was used to identify the coefficient of this model. The result shows that using the physiological indexes of drivers can well identify their fatigue status and find out the relationship between their driving operation and their fatigue status. This research is helpful to the establishment of the relation model between driving operation and fatigue status of drivers.
