摘 要：In the field of advanced driver assistance systems,researchers and developers make great efforts to reduce drivers workload and to keep it on an ideal level *** the course of these efforts the physiological detection of workload,also in commercial vehicles,is coming more and more to the fore.A total of 44 driving situations have been identified in an exploratory survey of truck drivers which are relevant for the resulting driver *** includes various driving situations as well as driving maneuvers and traffic situations,such as high traffic density or different weather *** regard to objectively measurable parameters,these 44 situations were examined in a study with 37 professional truck drivers in the dynamic truck driving simulator of the Institute of Automotive *** addition to the changes in pupil dilation the electrodermal activity and a subjective assessment based on the Rating Scale of Mental Effort(RSME)were used in order to detect the mental *** results were validated in a field trial subsequent to this driving simulator *** the selection of the test course,particular attention was paid to a high degree of similarities between realworld and simulated roadway *** evaluation of the electrodermal activity measured in the real traffic study as an indicator for mental workload revealed the *** most demanding activity during the performed study was making phone calls,whereby the participants were confronted with a planning *** attention to an accessing car was also a high demanding task with anticipatory requirements with respect to the car driver s *** routine tasks such as crossing intersections,the evaluation of electrodermal activity does not lead to statistical differences between the investigated *** contrast,a self-report measurement of mental workload conducted in parallel shows sufficient sensitivity and therefore significant differences between th
