  • Patent number: 11921504
    Abstract: Techniques for generating simulations to evaluate an update to a controller. The controller may be configured to control one or more functionalities of an autonomous and/or a semi-autonomous vehicle. A simulation computing system may receive a request to evaluate a first controller. The simulation computing system may generate a simulation based on data associated with a previous operation of the vehicle in an environment, the previous operation being controlled by a second controller (e.g., standard for evaluation, control version, etc.). The simulation computing device may cause the first controller to control a simulated vehicle in the simulation and may determine whether to validate the update to the controller based on a difference between first metrics associated with a control of the simulated vehicle by the first controller and second metrics associated with a control of the vehicle by the second controller.

  • Patent number: 11912302
    Abstract: This application relates to techniques for determining whether to engage an autonomous controller of a vehicle based on previously recorded data. A computing system may receive, from a vehicle computing system, data representative of a vehicle being operated in an environment, such as by an autonomous controller. The computing system may generate a simulation associated with the vehicle operation and configured to test an updated autonomous controller. The computing system may determine one or more first time periods associated with the vehicle operations that satisfy one or more conditions associated with engaging an autonomous controller and one or more second time periods associated with the vehicle operations that fail to satisfy the one or more conditions. The computing system may enable an engagement of the autonomous controller during the one or more first time periods and disable the engagement during the one or more second time periods.

  • Patent number: 11897506
    Abstract: A vehicle may include an active ride comfort tuning system that reactively and/or proactively alters a parameter of a system of the autonomous vehicle to mitigate or avoid interruptions to ride smoothness. For example, the comfort tuning system may alter a parameter of a drive system, suspension, and/or a trajectory cost function. The comfort tuning system may alter the parameter based at least in part on detecting and/or receiving a comfort indication, determined based on sensor data, user input, or the like.

  • Publication number: 20230334470
    Abstract: A delegate interoperability network for may include a plurality of delegates instantiated on a plurality of different blockchains. The delegate network may enable blockchain interoperability by receiving, at a first delegate instantiated on a first blockchain, a request to initiate, on a second blockchain, a blockchain action on behalf of a user. The method further includes generating, by the first delegate, a unique delegate network address associated with the user and the first blockchain. The method further includes determining, by the first delegate, whether the second blockchain has sufficient gas token liquidity to complete the blockchain action. The method further includes based at least in part on determining that the second blockchain has sufficient gas token liquidity, sending, to a second delegate instantiated on the second blockchain, a first message to initiate the blockchain action.

  • Patent number: 11780466
    Abstract: A vehicle may include an active ride comfort tuning system that reactively and/or proactively alters a parameter of a system of the autonomous vehicle to mitigate or avoid interruptions to ride smoothness. An indication that a ride smoothness interruption occurred at a vehicle may be generated at the vehicle and/or at a remote computing device. The remote computing device may determine an altered parameter for controlling how the vehicle operates and a ruleset for when the vehicle should implement the altered parameter in place of a nominal parameter.

  • Patent number: 11738777
    Abstract: This application relates to techniques for dynamically determining whether to engage an autonomous controller of a vehicle. A computing system may receive a request to engage the autonomous controller (e.g., autonomous mode) of the vehicle. In some examples, the request may be received from a simulation computing system configured to test an updated autonomous controller in a simulation. Based on a determination that conditions associated with engaging autonomy are satisfied, the computing system engages the autonomous controller. Based on a determination that conditions associated with engaging autonomy are not satisfied, the computing system disables the engagement of the autonomous controller such that the vehicle is controlled according to an initial operational mode (e.g., manual mode, semi-autonomous mode, previous version of the autonomous controller, etc.).

  • Publication number: 20230097121
    Abstract: Techniques for aggregating costs associated with one or more heat maps to control a vehicle in an environment are discussed herein. A vehicle computing device can implement a model to determine heat maps and respective cost information for different features of the environment based on sensor data. The vehicle computing device can output a planned trajectory for the vehicle based on combining the heat maps. The techniques can also include determining a rationalization or root cause detailing reasons why the planned trajectory was determined.

  • Patent number: 11603095
    Abstract: Techniques for controlling a vehicle based on a collision avoidance algorithm are discussed herein. The vehicle receives sensor data and can determine that the sensor data represents an object in an environment through which the vehicle is travelling. A computing device associated with the vehicle determines a collision probability between the vehicle and the object at predicted locations of the vehicle and object at a first time. Updated locations of the vehicle and object can be determined, and a second collision probability can be determined. The vehicle is controlled based at least in part on the collision probabilities.

  • Patent number: 11541909
    Abstract: Determining whether another entity is coordinating with an autonomous vehicle and/or to what extent the other entity's behavior is based on the autonomous vehicle may comprise determining a collaboration score and/or negotiation score based at least in part on sensor data. The collaboration score may indicate an extent to which the entity is collaborating with the autonomous vehicle to navigate (e.g., a likelihood that the entity is increasingly yielding the right of way to the autonomous vehicle based on the autonomous vehicle's actions). A negotiation score may indicate an extent to which behavior exhibited by the entity is based on actions of the autonomous vehicle (e.g., how well the autonomous vehicle and the entity are communicating with their actions).

  • Publication number: 20220185266
    Abstract: A vehicle computing system may implement techniques to improve collision prediction and avoidance between a vehicle and objects in an environment. A vehicle computing system of the vehicle generates a relevance polygon associated with a planned path of the vehicle based at least in part on a speed associated with the vehicle traveling through the environment. The vehicle computing system identifies objects in the environment and determines whether the objects are located within a boundary of the relevance polygon. Based on a determination that an object is within the boundary, the vehicle computing system determines that the object is relevant to the vehicle and includes data associated therewith in vehicle control planning considerations.
