Has Electronic Stability Control Reduced Rollover Crashes?
Vehicle rollovers are one of the most dangerous crash modes in the US – accounting for 35% of all occupant fatalities annually. Electronic Stability Control (ESC) has been estimated to have an effectiveness of 16.7% for all non-rear-end crashes and 56.2% for all control loss crashes and thus has great promise to alleviate the rollover problem. The objectives of this research were (1) to estimate the effectiveness of ESC in preventing rollover crashes and (2) to identify cases which ESC did not prevent the rollover to prioritize advanced countermeasure development. All passenger vehicles and light trucks and vans that experienced a rollover from 2006 to 2015 in the National Automotive Sampling System Crashworthiness Database System (NASS/CDS) were analyzed. Each rollover was assigned a crash scenario based on the crash type, pre-crash maneuver, and pre-crash events.
