ABSTRACT
Recently various driving support systems, including Adaptive Cruise Control (ACC) and Adaptive Front Lighting System (AFLS), have been introduced to improve safety and reduce driver stress. These systems are based on a hypothesis from traditional cognitive sciences that assumes that driving operations are performed by a three-step process: cognition, decision-making, and operation. In current driver assistant systems (some of which are listed above), these three steps are replaced by on-vehicle sensors, ECUs, and actuators, respectively. For example, on-vehicle sensors perform the cognition of such physical variables as distance from obstacles, velocity, or acceleration. Then, ECUs integrate the sensor outputs and finally control actuators.
