Automobile sub-limit performance maneuvers and measures were developed for investigating the influence of vehicles-in-use steering, suspension, and brake system degradation and tire factors on vehicle handling. The maneuvers and performance measures are directed at vehicle static and dynamic stability characteristics, vehicle controllability, driver workload, and vehicle path stability under unbalanced force or moment disturbance inputs. The NHTSA automobile simulation was modified to incorporate various steering and suspension degradations and was employed to guide selection of maneuver and component degradation levels for full-scale vehicle testing. A multi-vehicle test plan was outlined to extend the current vehicle data base, to refine the maneuvers and procedures developed in this program, and to initiate development of meaningful acceptability criteria for vehicles-in-use sub-limit performance testing.
