An Experimental Examination of Double Lane Change Maneuvers That May Induce On-Road, Untripped, Light Vehicle Rollover 2003-01-1009

Phase IV of the National Highway Traffic Safety Administration's (NHTSA) rollover research program was performed during the spring through fall of 2001. The objective of this phase was to obtain the data needed to select a limited set of maneuvers capable of assessing light vehicle rollover resistance. Five Characterization maneuvers and eight Rollover Resistance maneuvers were evaluated [1].

This paper is “Volume 2” of a two-paper account of the research used to develop dynamic maneuver tests for rollover resistance ratings. Test procedures and results from four Rollover Resistance maneuvers are presented. The Consumers Union Short Course (CUSC), ISO 3888 Part 2, Ford Path Corrected Limit Lane Change (PCL LC), and Open-Loop Pseudo Double Lane Changes are discussed. Details regarding the NHTSA J-Turn, and the three fishhook maneuvers are available in “Volume 1” [2].

Each maneuver was evaluated based upon its Objectivity and Repeatability, Performability, Discriminatory Capability, and Appearance of Reality. For each maneuver evaluation factor, the authors assigned an adjectival rating of Excellent, Good, Satisfactory, Bad, or Very Bad.
