Abstract
One of the main reasons for accidents especially on freeways is
falling too short of a safe headway distance. This behavior is
often unintentional and caused by a lack of attention and the
driver's inability for precise distance estimation.
Within TÜV Rheinland's PROMETHEUS project "Integrated
MMI-Solution for LOngitudinal COntrol (IMMIS-LOCO)' a driver
assistance concept based on a visual display, an active gas pedal
and an autonomous brake system (ITT Automotive Europe) is realized
in an experimental vehicle. If the driver violates predefined
distance limits, the assistance system presents a tactile warning
(kick) on the active gas pedal combined wit a visual explanation
(pictogram) on the display. If the driver does not increase
distance the gas pedal is pushed back and the autonomous brake
system is activated. This intervention can always be controlled and
overridden by the driver. Based on field trials on German motorways
(Autobahn) with "naive subjects" driver acceptance and
safety consequences will be estimated. Layout of display, gas pedal
and brake system and experimental results will be presented
