Abstract
This article proposes a trailer-axle arrangement for a long combination vehicle, i.e., a B-train double with trailer tridem-axle groups, in which the lead-axle of each group is an active trailer steering axle, and the two rear-axles are passive trailer steering axles. Given this trailer-axle arrangement, a cost-effective active trailer steering system is devised. It is assumed that in low-speed curved-path negotiations, a passive trailer steering system, e.g., self- or command-steering, will operate, while in high-speed operations, the active trailer steering system is to be activated. For the active trailer steering control, three controllers are evaluated, which are designed using the linear quadratic regulator, linear quadratic Gaussian, and µ-synthesis techniques. The performance of these designs is assessed using closed-loop simulation. The insightful findings from this study will provide guidelines for designing active trailer steering systems for long combination vehicles.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
