Abstract: A vehicle body structure includes a roof rail structure, a pillar structure, a tube-like reinforcement member and an attachment assembly. The tube-like reinforcement member is shaped to include a first portion, a curved portion and a second portion such that the first portion is fixed within and extends along a portion of the roof rail structure and the second portion extends downward within and extends along an upper portion of the pillar structure. The attachment assembly includes a bracket and a positioning member disposed within the pillar structure. The bracket is fixedly attached to the pillar structure. The second portion of the tube-like reinforcement member extends through an oversized opening in the bracket. The tube-like reinforcement member is fixedly attached to the positioning member and the positioning member being fixedly attached to the bracket.

Abstract: Methods and systems for providing remote support and negotiating problem situations of autonomous operation of vehicles based on signal states and vehicle information are described. A system comprises a memory and a processor configured to execute instructions stored in the memory to: assign vehicles to support queues based on state data, generate a map display including locations of the vehicles, and generate a state display including the support queues, vehicle manager indicators corresponding to the support queues and state indicators corresponding to the state data.

Abstract: Methods and systems for controlling a vehicle are herein disclosed. A method includes receiving vehicle data and external data from a vehicle control system of a vehicle and generating an environment representation of an area of the transportation network proximate to the vehicle location. The method includes displaying the environment representation in a GUI and receiving a solution path via the graphical user interface, the solution path indicating a route and one or more stop points. The method includes transmitting the route to the vehicle including a respective geolocation of each of the one or more stop points. The vehicle receives the route and begins traversing the transportation network based on the solution path. The method includes receiving updated vehicle data and/or updated external data from the vehicle and updating the environment representation based thereon. The method includes displaying, the updated environment representation via the graphical user interface.

Abstract: Autonomous vehicle operational management may include traversing, by an autonomous vehicle, a vehicle transportation network. Traversing the vehicle transportation network may include generating an autonomous vehicle operational control environment for operating scenario-specific operational control evaluation module instances. A scenario-specific operational control evaluation module instance may be an instance of a respective scenario-specific operational control evaluation module. A scenario-specific operational control evaluation module may model a respective distinct vehicle operational scenario. A scenario-specific operational control evaluation module instance may generate a respective candidate vehicle control action responsive to the respective corresponding distinct vehicle operational scenario. Traversing the vehicle transportation network may include operating a scenario-specific operational control evaluation module instance, receiving a first candidate vehicle control action from the first scenario-specific operational control evaluation module instance, and traversing a portion of the vehicle transportation network based on the first candidate vehicle control action.

Abstract: A vehicle air handling system includes an air duct housing, a particulate sensor, a first air blower and an electronic controller. The air duct housing has an air inlet and a passenger compartment vent. The particulate sensor is configured to detect a particulate level of particulates in the air duct housing. The first air blower is disposed in the air duct housing to move air within the air duct housing. The electronic controller is operatively coupled to the particulate sensor and the first air blower. The electronic controller is configured to operate the first air blower to reverse an air direction of the first air blower away from the passenger compartment vent upon detection of the particulate level of the particulates in the air duct housing being equal to or greater than a predetermined particulate threshold level in the air duct housing.

Abstract: Traversing a vehicle transportation network, by a vehicle, may include determining vehicle operational information, determining a metric location estimate for the vehicle using the vehicle operational information, determining operational environment information of a portion of the vehicle transportation network, determining a topological location estimate for the vehicle within the vehicle transportation network using the metric location estimate and the operational environment information, and traversing the vehicle transportation network based on the topological location estimate for the vehicle. The operational environment information can include sensor data of a portion of the vehicle transportation network that is observable to the vehicle. The sensor data can comprise remote vehicle location data. To determine the metric location estimate, a non-linear loss function with a Kalman filter may mitigate effects of un-modeled sensor error(s). Techniques using Hidden Markov Models and the Earth Mover's Distance to determine the topological location estimate are also described.

Abstract: An outer door panel and an inner door panel are fixed to one another defining a cavity therebetween. A door handle assembly is fixedly attached to the outer door panel, with at least a portion of the door handle assembly overlaying an inboard surface of the outer door panel within the cavity. An inboard portion of the door handle assembly has a connection structure. An upwardly extending bracket within the cavity is fixed to an upper end and a lower end of at least one of the inner door panel or the outer door panel. The upwardly extending bracket is spaced apart from the door handle assembly. A vibration absorbing member has a first end fixed to the connection structure of the door handle assembly and a second end attached to the upwardly extending bracket at a location spaced apart from upper and lower ends of the upwardly extending bracket.

Abstract: A membrane electrode assembly for a fuel cell comprises a proton exchange membrane having an anode side and a cathode side. An anode catalyst layer is on the anode side of the proton exchange membrane and a cathode catalyst layer is on the cathode side of the proton exchange membrane. Each of the anode catalyst layer and the cathode catalyst layer comprises a metal alloy. A gas diffusion layer is on each of the anode catalyst layer and the cathode catalyst layer opposite the proton exchange membrane. A sacrificial intercalating agent is between the proton exchange membrane and one of the anode catalyst layer and the cathode catalyst layer, the sacrificial intercalating agent having sulfonate sites that attract metal cations resulting from dissolution of the metal alloy prior to the metal cations reaching the proton exchange membrane.

Abstract: Trajectory planning for an autonomous vehicle is disclosed. A method for planning a trajectory for an autonomous vehicle includes determining a coarse driveline from a first location to a second location; determining a strategic speed plan for the coarse driveline; removing lateral discontinuities in the coarse driveline based on the strategic speed plan to generate an adjusted coarse driveline; and generating lateral constraints around the adjusted coarse driveline and a discrete-time speed plan based on observed objects.
