• Abstract:
  The report describes the forward collision warning (FCW) and subject vehicle (SV) braking onset. Three vehicles, a 2017 Mercedes E300, a 2018 Nissan Leaf, and a 2017 Volvo S90, were evaluated using the Global Vehicle Target Revision E in three rear-end crash scenarios: lead vehicle stopped, lead vehicle moving, and lead vehicle decelerating. The vehicles were evaluated in three levels of automation, levels 0, 1, and 2 (crash imminent braking only, adaptive cruise control enabled, and adaptive cruise control plus lane centering control enabled). Based on available data from the three vehicles used in this study, SV braking onset timing does not appear to have been affected by POV offset during tests performed in automation levels 1 or 2 (i.e., tests performed with ACC enabled).
