Through extensive real-vehicle calibration and validation, the proposed approach effectively regulates target speed differentials, leading to a significant improvement in vehicle propulsion efficiency. This research not only advances overall driving performance but also establishes a foundational framework for future adaptive control of clutch torque transfer characteristics.
