abstract = { This paper presents a simulation-based human-in-the-loop methodology for the early-stage assessment of longitudinal shift comfort in two-speed battery electric vehicles. Representative upshift profiles are generated in a longitudinal MATLAB/Simulink model and reproduced in a dynamic driving simulator dedicated to longitudinal dynamics studies. Objective evaluation is based on vehicle acceleration and jerk criteria, while subjective assessment uses five-point Likert ratings of daily use acceptance, comfort, perceived acceleration interruption, and shift noticeability. Statistical analysis of the results confirms clear and systematic differences between the investigated configurations. Interruption-related metrics align particularly well with subjective ratings of perceived interruption and comfort, confirming traction continuity as the dominant contributor to shift comfort perception, whereas jerk contributes mainly to the noticeability of the shift event. The proposed approach therefore enables a development-oriented assessment of shift comfort before physical drivetrain prototypes are available and provides a basis for future work on a mathematical correlation model and on validation against a physical drivetrain.
