Abstract:
Although dynamic driving simulators are widely used in the automotive development process, they are not commonly used for the evaluation of drivetrain drivability. One reason is the limited simulator workspace which requires most maneuvers to be scaled down. However, a tip-in/back-out maneuver, which is often used for drivability assessment, can be implemented in a driving simulator without downscaling. Characteristics of the maneuver are high transient torques which cause comfort reducing oscillations, so called shuffle. In this paper two experiments are reported on the dynamic driving simulator of the Institute for Mechatronic Systems in Mechanical Engineering (IMS) to investigate the absolute perception threshold above which shuffle is recognized. For this purpose, a method is introduced to mathematically approximate recorded tip-in/back-out maneuvers for the implementation on a simulator control. With the method an isolated online manipulation of maneuver parameters, e. g. the shuffle amplitude, is possible. The investigations reveal, that the maximum acceleration due to the tip-in masks the shuffle and hence has a major impact on the perception threshold.
