It was the aim of this research to develop a warning strategy for a driving assistance system which gives information to the driver about a pending critical driving situation relating to the friction potential. The safety margin, respectively the use of the friction potential in the lateral direction, was primarily used as the most important safety parameter for the development of information, support and warning strategies. The human information processing and control mechanisms used during car driving were considered in the search and for evaluation of possibilities to inform the driver. The visual, auditory and haptic (kinesthetic and tactile) channels have been considered. An active accelerator pedal yielded the best result to transmit information to the driver. The most detectable signals were the combination of haptic and acoustic signals, which gave the best support for the driver. (A)
