Behavioral Aspects of Driver Assistance Systems

Weller, Gert / Schlag, Bernhard

Abstract Driving a car is a task that requires predominantly cognitive resources. Which resources are required exactly and to which amount they are required depends on the characteristics of the situation. The situation comprises the driver, the vehicle, and the environment. Advanced driver assistance systems (ADAS) change the situation and thus the task of driving a car in several aspects. These changes have an impact on the driver and mainly concern workload, situation awareness, and mental models. Changes therein can result in behavioral changes subsumed under the term behavioral adaptation. Behavioral adaptation can be negative or positive or even both depending on the perspective. However, when developing and designing ADAS, the nature of the aforementioned changes resulting in behavioral adaptation must be understood and must be taken into account. Behavioral changes must further be an integral part of evaluating the effect of such systems. Because of the constant technological progress, ADAS increasingly constitute a step toward full automation. Therefore, experiences in other domains in which automation has reached higher levels than in passenger cars must also be taken into account. This chapter provides the basis to understanding such ADAS-related effects.
