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: A positioning tool is disclosed that is configured for use with a front-end module (FEM) of a vehicle to align the FEM with a hood of the vehicle. The positioning tool includes: a body; a receiving member that is connected to the body and configured for engagement with the hood of the vehicle; and at least one engagement member that is supported by the body. The at least one engagement member is configured to interface with the FEM such that movement of the positioning tool causes corresponding movement of the FEM, whereby the FEM is aligned relative to the hood of the vehicle upon closure of the hood of the vehicle.

Abstract: An apparatus for traversing a vehicle transportation network by an autonomous vehicle (AV) includes a human-autonomy teaming manager. The manager includes a first processor configured to initiate a dialogue associated with a predefined dynamic task sequence that is responsive to a condition experienced by the AV while traversing from a starting location to an ending location within the vehicle transportation network. The sequence is one of a plurality of predefined dynamic task sequences that uses multiple agents to resolve the condition. The manager receives, from an interface accessible to a human agent, an input responsive to the dialogue. The input confirms the sequence as a selected predefined dynamic task sequence or selects an other of the plurality of predefined dynamic task sequences as the selected predefined dynamic task sequence. The manager delegates tasks of the selected predefined dynamic task sequence to resolve the condition.

Abstract: Object avoidance by an autonomous vehicle (AV) is disclosed. A method includes detecting a first object along a coarse driveline of a drivable area of the AV; receiving a predicted path of the first object; determining, based on the predicted path of the first object, an adjusted drivable area; and determining a trajectory of the AV through the adjusted drivable area. A system includes a trajectory planner configured to detect a first object along a coarse driveline of a drivable area of the AV; receive a predicted path of the first object; determine, based on the predicted path of the first object, an adjusted drivable area; and determine a trajectory of the AV through the adjusted drivable area.

Abstract: A vehicle door assembly includes an inner door panel that partially defines a cavity therein, a door handle assembly, a main reinforcing bracket, a first reinforcing bracket and a vibration absorbing member. The first reinforcing bracket has an upper end fixedly attached to the main reinforcing bracket and to a rearward area of the inner door panel within the cavity below the door handle assembly. The vibration absorbing member has an outboard surface, an inboard surface and a main projection that extends forward from the main body. The main projection is fixed to the first reinforcing bracket such that the main body is rearward of the first reinforcing bracket. The outboard surface is shaped and dimensioned to correspond to the overall shape of the inboard portion of the door handle assembly.

Abstract: A vehicle tire assembly having a plurality of flexible spoke portions that extend from an outer annular ring to and inner annular ring. Adjacent pairs of the flexible spoke portions define a plurality of gaps therebetween. A plurality of electro-active members, are disposed radially inward from the outer annular ring and radially outward of the inner ring. The plurality of electro-active members are configured such that in the absence of an electric current flowing therethrough, the plurality of electro-active members flex in response to flexing of the plurality of flexible spoke portions. In the presence of an electric current flowing through the plurality of electro-active members, the plurality of electro-active members become more rigid and less flexible adding corresponding stiffness to the plurality of flexible spoke portions.

Abstract: An evaporative emission control system for a vehicle includes an engine, a fuel tank connected to the engine and a reversible purge pump connected between the fuel tank and the engine. Fuel vapor generated in the fuel tank is supplied to the engine. The purge pump is operable in a first direction to supply the fuel vapor from the fuel tank to the engine and a second direction to supply air to the fuel tank. A purge control valve is connected between the reversible purge pump and the engine to control a flow of the fuel vapor to the engine.
