Experimental Examination of Selected Maneuvers That May Induce On-Road Untripped,211 Light Vehicle Rollover. Phase 2 of NHTSA's 1997-1998 Vehicle Rollover Research 211 Program

摘要

This report documents the results of testing potential maneuvers to measure on-211u001eroad, untripped, rollover propensity. Twelve test vehicles, covering a wide range 211u001eof vehicle types and classes were used. Three vehicles from each of the following 211u001ecategories were tested: passenger cars, light trucks, vans, and sport utility 211u001evehicles. The vehicles were tested with candidate vehicle characterization and 211u001euntripped rollover propensity maneuvers. The vehicle characterization maneuvers 211u001ewere designed to determine fundamental vehicle handling properties while the 211u001euntripped rollover propensity maneuvers were designed to produce two-wheel lift 211u001efor vehicles with relatively higher rollover propensity potential. The vehicle 211u001echaracterization maneuvers were Pulse Steer, Sinusoidal Sweep, Slowly Increasing 211u001eSteer, an Slowly Increasing Speed. The rollover propensity maneuvers were J-Turn, 211u001eJ-Turn with pulse Braking, Fishhook No. 1 and No. 2, and Resonant Steer.
