The development of driver assistance systems following usability criteria

Increasing numbers of intelligent driver assistance systems are now being installed in motor vehicles to support drivers. In order to ensure that the stress reduction benefits obtained from these systems are not nullified or even outweighed by new stresses at the vehicle's man-machine interfaces, the systems' control concepts must be designed to high ergonomic standards. This paper seeks to identify design weaknesses in assistance systems by presenting criteria that must, on the one hand, be observed when designing the control concept of a new assistance system and, on the other hand, be applied when assessing the man-machine interfaces of assistance systems already installed in a vehicle.
