<div class="section abstract"><div class="htmlview paragraph">Testing was conducted in daytime and nighttime conditions at four speeds – 35, 50, 55, and 60 miles per hour (mph) – to evaluate the performance of the audible and visual forward collision warning (FCW) system in a WABCO OnGuardACTIVE collision mitigation system (CMS) while approaching a foam stationary vehicle target (SVT). Testing measured the time to collision (TTC) values utilizing a VBOX data acquisition system as well as an “analog” system utilizing synced cameras and a reference line painted on the test track. WABCO Toolbox was utilized to download OnGuard data from the Freightliner after each test; this data was then compared to the data acquired by the VBOX data acquisition system. The results of the testing provide valuable information to collision investigators on the performance of the WABCO OnGuardACTIVE Collision Mitigation System on stationary vehicles. In addition, a review of the data imaged from the OnGuardACTIVE’s radar using WABCO Toolbox will be compared to the testing data.</div></div>
<div class="section abstract"><div class="htmlview paragraph">The Bendix Wingman Advanced – a radar-only collision mitigation system (CMS) available on commercial vehicles – was evaluated in two separate test series to determine its performance in simulated stationary vehicle rear collision scenarios. In the first series of tests, evaluations were conducted in daytime and nighttime conditions at two speed ranges – 35 and 45-50 miles per hour (mph) – to evaluate the performance of the audible and visual forward collision warning (FCW) system in a Bendix Wingman Advanced CMS while approaching a stationary vehicle target (SVT) in a 2018 International 4300. Two years later, a second test series was conducted with a 2019 International 4300 traveling between 15 – 55 mph in low light and nighttime conditions approaching the SVT to evaluate the Bendix Wingman Advanced CMS on the truck. Both test series sought to determine the maximum speed the system would warn prior to the test driver swerving around the SVT. The tests utilized a foam stationary vehicle target built using Euro NCAP specifications as a guide. Testing measured the time to collision (TTC) values utilizing VBOX data acquisition equipment as well as an “analog” system utilizing synced cameras and a reference line painted on the test track. The TTC at the left evasive steering maneuver by the test driver to avoid the stationary vehicle target was typically between 1.0 – 1.5 seconds. The results of the two series of tests provide valuable information about the performance of the Bendix Wingman Advanced CMS approaching stationary vehicles in rear collision scenarios.</div></div>
