  1. AEBS/LDWS-07-05 20100913 Driver Reaction Time

  2. AEBS-warning (audible/haptical) Recognition Of warning Focus on event Base re- action time Moving foot Brake res- ponse time Pressure Built up ABS braking time Starting muscular reaction Brake pressure increase Touch brake pedal Event Recognition Start ABS-Control Event analysing Vehicle stop 0,48s 0,45s 0,19s 0,05s 0,17s ??? 1,34s 1,12s M 0,93s 1,17s „Kölner-Modell“ The „Kölner-Modell“ was defined in 1982 and is still today legal basis for the German legal practice for traffic jurisdiction for passenger cars. (Burkhardt)

  3. Shorter Longer • Anticipation of a incident • Age of the driver • Gender (female) • Medicine, alcohol • Wrong shoes • Imminent danger • More than one alternatives • Visibility conditions (darkness, low sun…) • Driver distraction (accident, fire, woman…) Influence factors Subjective!!

  4. Overview of research results

  5. CLEPA opinion:to give the driver a realistic chance, to react on the warning, we propose a warning time of min. 2s before the system reacts with emergency braking
