  • Publication number: 20240246511
    Abstract: A system for key absence management in a vehicle configured to be started by an electronic key fob includes a key absence management controller that implements a method configured to authorize starting of the vehicle by monitoring presence and absence of the electronic key fob in the vehicle. If the controller finds the electronic key fob to be present in the vehicle, then the controller authorizes starting of the vehicle. If the controller finds the electronic key fob to be absent from the vehicle, then the controller authorizes starting of the vehicle based on detection of a keyless authority indicator. A vehicle configured to be started by an electronic key fob includes the system with the controller that implements the method.

  • Publication number: 20240249137
    Abstract: Disclosed are embodiments for a deep learning optimizer for fine-tuning while dynamically mitigating catastrophic forgetting. In some aspects, a method includes saving an original state of a model to a buffer, the original state comprising original weights of the model; apply new gradients to intermediate model states of the model during at least one intermediate training step of training of the model; calculate, at a final training step of the training, a displacement vector representing a difference between current weights of the model and the original weights of the model; responsive to the displacement vector and a final gradient of the final training step being inconsistent in terms of gradient direction, perform an orthogonal projection of the final gradient on the displacement vector to generate an orthogonal gradient; and applying the orthogonal gradient to the original state of the model at the final training step of the training.

  • Publication number: 20240246571
    Abstract: An AV may determine a degradation score based on data indicating a condition of an environment where the AV operates to provide a service. The degradation score may indicate a degradation in a performance of the AV (e.g., one or more sensors of the AV) under the condition. After determining that the degradation score is higher than a threshold, the AV may pause the service, e.g., by moving out of the traffic lane or pulling over. The AV may re-check the condition later and determine a new degradation score. After determining that degradation score is lower than the threshold, the AV may resume the service, e.g., by moving back to the traffic lane. The AV may determine that the degradation score is higher than another threshold and in response to the determination, stops where it is, e.g., in a traffic lane. The AV may request remote assistance or retrieval.
