Abstract

fetched live from OpenAlex

The aim of this paper is to obtain efficient operation of the components in the series-parallel drivetrain in order to develop an optimal power distribution system. This will be done through the use of efficiency maps of the electric motor and the engine. Based on the information obtained about the speed and torque characteristics, the aim would be to operate the motor and the engine in a defined region of speed and torque. An added objective of the strategy is the capability to maximize the energy captured through regenerative braking. This technique will be demonstrated by simulating the power distribution for an actual driving cycle in order to obtain better understanding of the procedure and achieve realistic optimization.

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.
