| Abstract | From a methodological perspective, the telematics-based, large-scale data collection technique has strengths for evaluating safety systems, including cost, sample size, drivers using their own vehicles, ability to look at long-term effects, data efficiency, and the ability to get “rapid-turnaround” large-scale results. These strengths are particularly notable for examining rare events such as last-second automatic braking (or steering), near crash, or crash events. This type of telematics-based data collection is also helps under-stand impacts of safety systems that are rapidly emerging globally. The ability to collect data rapidly at this scale (in this case, ~1 million miles of driving data per month), especially when events are rare, is critical to understanding the real-world performance of these and future vehicle systems. This field study report uses high-priority data addressing driver assistance actions and corresponding driving behavior associated with production crash avoidance-equipped passenger vehicles. A prior year-long study addressed forward collision warning (FCA) and lane departure warning (LDW) technologies by capturing data from almost 2,000 vehicles. This report focuses on automatic emergency braking (AEB) and dynamic brake support (DBS) systems offered by GM as “Front Automatic Braking” (FAB) and “Intelligent Brake Assist” (IBA), respectively. These systems are jointly referred to as the Collision Preparation System (CPS). The goal of this field study, focused on examining a production FAB and IBA system, is to study system behavior, driver behavior, safety-relevant findings, and observations on system performance and maturity. As in the prior work, this study made use of the unique telematic capability of GM’s OnStar-equipped vehicles to gather data in participating vehicles. Data was captured on 1,021 production vehicles (all MY 2015 Cadillacs) equipped with FAB and IBA from consenting vehicle owners over a 1-year period; the vehicles involved operated in 46 of 50 States. |
