The Bendix Wingman Fusion – a radar and camera collision mitigation system (CMS) available on commercial vehicles – was evaluated in two separate test series to determine its performance in simulated rear collision scenarios. In the first series of tests, evaluations were conducted in daytime, nighttime, and rainy conditions between 15 to 58 miles per hour (mph) to evaluate the performance of the audible and visual forward collision warning (FCW) system in a first-generation Bendix Wingman Fusion CMS while approaching a stationary live vehicle target (SLVT) in a 2017 Kenworth T680. A second test series was conducted with a 2017 Kenworth T680 traveling at 50 mph in daytime conditions approaching a decelerating vehicle to evaluate the Bendix Wingman Fusion CMS on the truck. Both test series sought to determine the maximum distance the system would warn prior to the test driver swerving around the SLVT or moving vehicle target.

The purpose of this paper is to demonstrate the differences in braking capability of the different types of tires through data collected from single variable testing. The only variable in these tests was the type of tire installed. Three different tire types; summer, all season, and winter, all of the same size, were tested in moderate ambient temperature on wet and dry asphalt surface with a single vehicle. The braking tests were conducted with ABS actived and deactivated for modulated and locked wheel friction comparison of the tire types. Accident reconstructionists rely on accurate friction coefficients to calculate speeds from skid and yaw marks left at a collision scene. Maximum effort braking performance, whether locked wheel or ABS modulated, is influenced mainly by the road to tire interaction and is affected by the type of tire. High performance, “Summer”, tires are increasingly available as Original Equipment Manufacturer fitment.
