Real-World Driving CO2 Emissions and Engine Thermal Efficiency Evaluation of Hybrid Vehicles: A Regression-Based Parameter Identification Approach

Real-world driving tests reflect vehicle performance in everyday use, but extracting energy conversion data from extensive measurements remains challenging. The study compared a hybrid electric vehicle and a plug-in hybrid electric vehicle, with the latter operated in charge-sust...

Multibody dynamic modelling and guided reinforcement learning for a novel air suspension system of semi-trailers

Vehicle vibrations during long-haul logistics transportation can significantly degrade ride comfort and increase the risk of cargo damage. To address this issue, this paper proposes a novel torsion-beam air suspension configuration and a guided reinforcement learning–based semi-a...
