  • Patent number: 12103561
    Abstract: Techniques relating to monitoring map consistency are described. In an example, a monitoring component associated with a vehicle can receive sensor data associated with an environment in which the vehicle is positioned. The monitoring component can generate, based at least in part on the sensor data, an estimated map of the environment, wherein the estimated map is encoded with policy information for driving within the environment. The monitoring component can then compare first information associated with a stored map of the environment with second information associated with the estimated map to determine whether the estimated map and the stored map are consistent. Component(s) associated with the vehicle can then control the object based at least in part on results of the comparing.

  • Publication number: 20240311172
    Abstract: Managing execution of eBPF program capabilities is provided. A comparison of a currently in use helper-id list with an allowable helper-id list of an eBPF program is performed. It is determined whether a set of unallowable helper-ids exists that is included in the currently in use helper-id list but not in the allowable helper-id list based on the comparison. A blocked helper-id list of the eBPF program that includes the set of unallowable helper-ids and a corresponding unallowable capability of each respective unallowable helper-id is generated in response to determining that the set of unallowable helper-ids does exist. The set of unallowable helper-ids and the corresponding unallowable capability of each respective unallowable helper-id is removed from bytecode of the eBPF program in order to have only allowable helper-ids remain in the bytecode along with corresponding allowable capabilities of the eBPF program.

  • Patent number: 12091001
    Abstract: The present technology is directed to training and the use of a machine learning model to measure the safety of an autonomous vehicle (AV) driving in simulation. An AV management system can run a simulation of an AV autonomously piloting itself and collect simulation driving data. Further, the AV management system can parse the simulation driving data into kinematic and semantic environmental features and output a simulation safety score of the simulation based on the kinematic and semantic environmental features. The simulation safety score indicates a probability of a safety critical event such as a collision or a near-miss between the AV and the at least one simulated object in the simulation.
