Abstract

fetched live from OpenAlex

Energy management for the dual-motor all-wheel drive (AWD) electric vehicles (EV) is a trendy topic. The objective of this study is to develop a strategy that transfers the traction forces between two electric motors installed at the front and rear axles in order to reduce battery usage as much as possible. This paper takes the advantages of dynamic programming (DP) to obtain the global optimal results for this challenge. The discrete-time system model is firstly deduced by a backward formalism method, then DP computation is applied based on a Matlab toolbox. With the proposed strategy, the remaining battery state of charge under the New European Driving Cycle (NEDC) is up to 85.25% while satisfying all system constraints. The proposed solution can be the benchmark for other researchers to develop their energy management strategies for the mentioned kind of EV.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
