Waste heat recovery via combined cooling and power cycle (CCP-WHR) has become a promising energy-saving solution for refrigerated trucks owing to its capability for miniaturization, high efficiency, and multi-load supply. To ensure safety, stability, and efficiency under transient driving conditions, CCP-WHR needs to be adapted and coordinated with the complex and extreme fluctuations in energy conversion and transmission of the engine, which are difficult to explore in existing steady-state research. In this study, we establish a dynamic vehicle model for a refrigerated truck with CCP-WHR that can accurately track the driving cycle and adjust the operating mode. The dynamic characteristics, including vehicular operational performance (engine speed, torque, and waste heat parameters) and CCP-WHR output benefits (net work and cooling capacity), are analyzed with driving and load-carrying conditions as critical operating parameters. The comprehensive energy-saving performance of the entire vehicle is evaluated based on the proposed indicators. A refrigerated truck equipped with CCP-WHR demonstrated high adaptability to highway, suburban, and synthetic road conditions. Apart from achi
