Abstract
This paper proposes a robust model predictive control (MPC) approach for the design of Adaptive Cruise Control (ACC) systems. ACC enables a vehicle to follow a preceding vehicle autonomously and without any additional input form the driver. A reliable ACC must be able to handle driving constraints especially due to safety requirements of the car-following. In practice, constraint handling can be achieved by solving a constrained moving horizon control problem with optimizing a cost function using a prediction of the preceding vehicle's motion. However, uncertainty in the measured data and modeling errors can result in constraint violation and harsh undesired accelerations. The proposed Tube-based MPC ACC uses a tube resulted from bounded additive uncertainties in the system, to achieve robust control with guaranteed constraint handling. Simulations performed on a high-fidelity vehicle model in car-following scenario shows that the designed robust ACC is able to handle defined constraints while following a preceding vehicle in the presence of radar delay, modeling errors and disturbances.

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
