🤖 AI Summary
To address the lack of generalizable, high-accuracy power consumption models for gasoline, electric, and hybrid electric vehicles (HEVs), this paper proposes a scalable, data-driven framework. We first unify the modeling of their distinct powertrain dynamics and construct a dynamic feature set tailored for both instantaneous and cumulative power estimation. A multi-model regression ensemble integrates XGBoost, random forests, LSTM, and Transformer architectures, augmented with uncertainty quantification. Critically, the LSTM–Transformer synergy captures complex energy management strategies, substantially improving prediction robustness—particularly for HEVs and EVs. Experimental results demonstrate an instantaneous power estimation error of order 10⁻³ for gasoline vehicles and cumulative energy errors below 3.0%, 4.1%, and 2.1% for gasoline, hybrid, and electric vehicles, respectively. These outcomes validate the framework’s cross-platform generalizability and engineering applicability.
📝 Abstract
Accurate power consumption prediction is crucial for improving efficiency and reducing environmental impact, yet traditional methods relying on specialized instruments or rigid physical models are impractical for large-scale, real-world deployment. This study introduces a scalable data-driven method using powertrain dynamic feature sets and both traditional machine learning and deep neural networks to estimate instantaneous and cumulative power consumption in internal combustion engine (ICE), electric vehicle (EV), and hybrid electric vehicle (HEV) platforms. ICE models achieved high instantaneous accuracy with mean absolute error and root mean squared error on the order of $10^{-3}$, and cumulative errors under 3%. Transformer and long short-term memory models performed best for EVs and HEVs, with cumulative errors below 4.1% and 2.1%, respectively. Results confirm the approach's effectiveness across vehicles and models. Uncertainty analysis revealed greater variability in EV and HEV datasets than ICE, due to complex power management, emphasizing the need for robust models for advanced powertrains.
