Vehicles-in-Use Sub-Limit Maneuvers. Volume II: Multi-Vehicle Test Validation

摘要

The report presents results of a test program to validate applicability of six previously developed maneuvers in determining the influence of vehicle-in-use steering, suspension, and brake system degradations and tire factors on vehicle sub-limit handling. Six vehicles were tested which reflect subsystem design features and class size ranges representative of the majority of domestic and foreign vehicles-in-use in the United States. Test results show the maneuvers and procedures consistently produced measurable performance differences for the types and levels of subsystem degradations employed. The major handling decrement observed is nonlinear or discontinuous response for normal driver inputs (steer, brake, or throttle) which occurred for certain component degradations and vehicle acceleration levels.
