Abstract: Batch routing of autonomous vehicles is disclosed. A method may include maintaining a plurality of vehicle state data object instances that respectively correspond to a plurality of autonomous vehicles. The method includes obtaining a traffic condition location and determining a group of autonomous vehicles from the plurality of autonomous vehicles where the current route of each autonomous vehicle intersects the traffic condition location. The method also includes determining two or more subgroups of autonomous vehicles, and for each subgroup, determining a respective avoidance waypoint corresponding to the subgroup that is not on the current route of the autonomous vehicle. For each autonomous vehicle in the subgroup, the method includes determining an updated route based on the current route of the autonomous vehicle and the respective avoidance waypoint, generating a control instruction based on the updated route, and transmitting the control instruction to the autonomous vehicle.

Abstract: Autonomous vehicle operation with explicit occlusion reasoning may include traversing, by a vehicle, a vehicle transportation network. Traversing the vehicle transportation network can include receiving, from a sensor of the vehicle, sensor data for a portion of a vehicle operational environment, determining, using the sensor data, a visibility grid comprising coordinates forming an unobserved region within a defined distance from the vehicle, computing a probability of a presence of an external object within the unobserved region by comparing the visibility grid to a map (e.g., a high-definition map), and traversing a portion of the vehicle transportation network using the probability. An apparatus and a vehicle are also described.

Abstract: Methods and vehicles may be configured to gain experience in the form of state-action and/or action-observation histories for an operational scenario as the vehicle traverses a vehicle transportation network. The histories may be incorporated into a model in the form of learning to improve the model over time. The learning may be used to improve integration with human behavior. Driver feedback may be used in the learning examples to improve future performance and to integrate with human behavior. The learning may be used to create customized scenario solutions. The learning may be used to transfer a learned solution and apply the learned solution to a similar scenario.

Abstract: Autonomous vehicle operational management including blocking monitoring may include traversing, by an autonomous vehicle, a vehicle transportation network. Traversing the vehicle transportation network may include operating a blocking monitor instance, which may include identifying operational environment information including information corresponding to a first external object within a defined distance of the autonomous vehicle, determining a first area of the vehicle transportation network based on a current geospatial location of the autonomous vehicle in the vehicle transportation network and an identified route for the autonomous vehicle, and determining a probability of availability for the first area based on the operational environment information. Traversing the vehicle transportation network may include traversing a portion of the vehicle transportation network based on the probability of availability.

Abstract: Methods, apparatuses, and non-transitory computer readable storage media for a smart tutorial that adapts may assist in the operation of a vehicle including generating a situational profile that includes driver identity data, vehicle state data, or extra-vehicular state data. The situational profile is compared to assistance profiles that include aggregate identity data, aggregate vehicular state data, or aggregate extra-vehicular state data. The assistance profiles correspond to assistance instructions. Based on the comparison, similarity values corresponding to the assistance profiles are generated based on the comparison between the situational profile and the assistance profiles. The greatest similarity value corresponds to the assistance profile that is most similar to the situational profile. In response to the usage frequency value exceeding a usage frequency threshold value, the assistance instruction that corresponds to the assistance profile that is most similar to the situational profile may be selected.

Abstract: A vehicle battery temperature control system includes a battery (14), a housing (16), a heat exchanger (18) and a sensor (32). The battery (14) has a heat sink (20). The housing (16) has a chamber (24) that contains the battery (14) and saturated liquid coolant (26) that substantially immerses the heat sink (20) to receive the thermal energy to cause a phase change of the coolant (26) from a liquid to a vapor. The heat exchanger (18) removes thermal energy from the vapor to change the vapor to liquid, and returns the liquid to the chamber (24). Either a valve (38, 40) selectively conveying coolant (26) between the chamber (24) to an air-conditioning system or a heating device (52) is controlled based on a characteristic of the coolant (26) detected by the sensor (32) to remove or provide thermal energy to or from the coolant (26) based on a relationship between the characteristic of the coolant (26) and a threshold.
