Abstract
Crosswind disturbances may cause rollover or lane departure of truck and centre-axle-trailer (TCAT) combinations. To increase the safety of TCATs, a crosswind model is introduced and a 3 degrees of freedom (DOF) yaw-plane model is generated for developing a lateral stability control technique. Numerical simulation is conducted to examine the resulting dynamic responses under varying crosswind disturbances. To verify the 3-DOF model, the simulation results under a single lane-change (SLC) manoeuvre under a crosswind disturbance are compared against those based on the corresponding nonlinear TruckSim model. To effectively reject crosswind disturbances, a braking torque distribution strategy is proposed, by which the direct yaw moment control (DYC) is implemented using a fuzzy-PID algorithm. The simulation shows that the directional performance of TCAT is improved when the DYC activates under crosswind disturbances. The proposed active safety technique can reduce the risk of crosswind-induced instabilities of TCATs.

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
