Fahrer- und situationsspezifische Einflußfaktoren bei AICC-Fahrerassistenzsystemen

AICC (Autonomous Intelligent Cruise Control) systems, are investigated in the European PROMETHEUS and DRIVE projects, should support the driver in longitudinal vehicle control (speed and distance control). Driver- and situationspecific effects to be considered when developing or evaluating AICCs have been analyzed. Driving experiments were performed, whereby subjects' distance keeping behavior was monitored. Traffic situations relevant for AICC systems were identified and classified. The results of the subsequent situation analysis reveal driver- and situation-specific characteristics, e.g., in frequency and duration of various AICC situations, in distance distribution when following, and in minimum distance when approaching a preceding vehicle. From situation analysis, consequences were derived showing off capabilities and limitations of AICC systems on principle and of an "active gas-pedal" AICC in particular.
