Accelerating Reinforcement Learning via MPC Solver-Gradient Guidance for Weights-varying MPC

The paper introduces Solver-Gradient Guided Reinforcement Learning (SG‑RL), a method that augments standard RL with bounded gradients from a differentiable MPC solver to adapt cost‑function weights online. SG‑RL integrates solver‑gradient guidance into PPO through actor‑update scaling, policy loss, advantage estimation, and value‑function learning, achieving comparable or superior closed‑loop performance while requiring up to 70.6% fewer samples. Experiments on two autonomous racing platforms with intentional model mismatch demonstrate that SG‑RL outperforms both RL and gradient‑based policy learning baselines and generalizes zero‑shot to unseen environments.

Guiding End-to-End Driving Models with Endpoint-Constrained Trajectory Optimization

The paper introduces Endpoint-Constrained Optimization (ECO), a lightweight postprocessing layer that corrects intermediate waypoints of end-to-end driving policies while preserving the predicted endpoint. ECO does not require maps, privileged simulator state, or additional training, and can be applied to a wide range of waypoint-emitting policies. Experiments on two closed-loop simulators show that ECO significantly improves closed-loop performance, achieving top results in the HUGSIM Closed-Loop Driving Challenge and boosting scene scores on AlpaSim.

TerraZero: Procedural Driving Simulation for Zero-Demonstration Self-Play at Scale

arXiv:2607. 13028v1 Announce Type: cross Abstract: Training robust autonomous driving agents requires a simulator that is fast enough for reinforcement learning at scale, realistic enough to ground behavior in real-world map structure, and diverse enough to cover the safety-critical long tail that logged data rarely contains.

SlackDrive: Reclaiming Runtime Slack for Adaptive Driving Inference

SlackDrive is a pre‑inference compute allocator that dynamically selects the compute budget for each driving control step by reusing the realized latency from previous inferences. By profiling a small set of discrete budgets once, it estimates the current compute state online and chooses the highest‑utility budget that stays within the admissible latency envelope. On the NAVSIM v2 benchmark with DriveDreamer‑Policy, SlackDrive boosts latency‑constrained EPDMS performance by 21.7% compared to the best baseline, while full‑budget and token‑pruning approaches exceed the latency limits under runtime contention.
