Abstract: Various embodiments relate generally to autonomous vehicles and associated mechanical, electrical and electronic hardware, computer software and systems, and wired and wireless network communications to provide an autonomous vehicle fleet as a service. More specifically, systems, devices, and methods are configured to generate trajectories to influence navigation of autonomous vehicles. In particular, a method may include receiving path data to navigate from a first geographic location to a second geographic location, generating data representing a trajectory with which to control motion of the autonomous vehicle based on the path data, generating data representing a contingent trajectory, monitoring generation of the trajectory, and implementing the contingent trajectory subsequent to an absence of the trajectory.

Abstract: A lighting system of a vehicle may include light units and controllers for operating the light units. Each light unit is multifunctional in that the light unit may operate in various modes, which may be invoked at different times under varying circumstances. A light unit on the first end of a vehicle may operate as a headlight if the first end is the front end of the vehicle. On the other hand, the light unit may operate as a tail light if the first end is the rear end of the vehicle. Furthermore, the light unit may operate as a turn signal in either direction or brake light while the first end is the rear end of the vehicle. The light unit includes a lens array positioned to receive light from various light sources. The lighting system may operate in a fashion that allows for lighting redundancy on each end of the vehicle in the event of a lighting controller failure.

Abstract: A system for charging one or more batteries of a vehicle may include a charging box mounted to a vehicle to facilitate connection to a charge coupler from under the vehicle. The charge coupler may be configured to provide an electrical connection between an electrical power source and the charging box. A vehicle including the charging box may maneuver to a position above the charge coupler, after which electrical contacts of the charging box and the charge coupler may be brought into contact with one another. The charge coupler and/or the charging box may be configured to provide electrical communication between the electrical power source and the one or more batteries, so that the electrical power source may charge one or more of the batteries. Thereafter, the electrical contacts may be separated from one another, and the vehicle may maneuver away from the charge coupler.

Abstract: A system and method for determining whether a passenger is seated in a seating area and, based at least in part on detecting the passenger, engaging or disengaging a flap in a headrest. Such a headrest may span multiple seats so that a single headrest is used by multiple passengers. Each of one or more flaps in the single headrest may then be configured by the passenger to provide each passenger with their own privacy and comfort. By actively controlling the state of the flap, a uniform passenger experience may be created so that the flap is in the same state upon a passenger entering the vehicle. Further, examples of the headrest are designed and configured to couple directly, or indirectly, to a vehicle body, such that the headrest does not couple directly to a seat or passenger seating area.

Abstract: Vehicles may be composed of a relatively few number of “modules” that are assembled together during a final assembly process. An example vehicle may include a body module, a first drive module coupled to a first end of the body module, and a second drive module coupled to a second end of the body module. One or both of the drive modules may include a pair of wheels, a battery, an electric drive motor, and/or a heating ventilation and air conditioning (HVAC) system. One or both of the drive modules may also include a crash structure to absorb impacts. If a component of a drive module fails or is damaged, the drive module can be quickly and easily replaced with a new drive module, minimizing vehicle down time.

Abstract: A method for operating a fleet of vehicles may include determining a first set of parameters for operating a first vehicle as it travels to a destination, and determining a second set of parameters for operating a second vehicle. Consumption of the first set of parameters by the first vehicle may cause the first vehicle to accelerate, alter shocks and/or suspensions, and/or move into a free lane. Consumption of the second set of parameters by the second vehicle may cause the second vehicle to remain outside of a drive envelope of the first vehicle, between the first vehicle and the particular destination.

Abstract: Various embodiments relate generally to autonomous vehicles and associated mechanical, electrical and electronic hardware, computer software and systems, and wired and wireless network communications to provide an autonomous vehicle fleet as a service. In particular, a method may include monitoring a fleet of vehicles, at least one of which is configured to autonomously transit from a first geographic region to a second geographic region, detecting data indicating an event associated with the vehicle having a calculated confidence level, receiving data representing a subset of candidate trajectories responsive to detecting the event, which is associated with a planned path for the vehicle, identifying guidance data to select from one or more of the candidate trajectories as a guided trajectory, receiving data representing a selection of a candidate trajectory, and transmitting the selection of the candidate trajectory as of the guided trajectory to the vehicle.

Abstract: Techniques for assisting a passenger to identify a vehicle and for assisting a vehicle to identify a passenger are discussed herein. Also discussed herein are techniques for capturing data via sensors on a vehicle or user device and for presenting such data in various formats. For example, in the context of a ride hailing service using autonomous vehicles, the techniques discussed herein can be used to identify a passenger of the autonomous vehicle at the start of a trip, and can be used to assist a passenger to identify an autonomous vehicle that has been dispatched for that particular passenger. Additionally, data captured by sensors of the vehicle and/or by sensors of a user device can be used to initiate a ride, determine a pickup location, orient a user within an environment, and/or provide visualizations or augmented reality elements to provide information and/or enrich a user experience.

Abstract: An electrical system can include a power supply configured to provide electrical power to components at a time at which the electrical system experiences an electrical fault. The electrical system can include a first battery electrically coupled in parallel to a second battery via an electrical bus, whereby the first and second batteries can provide electrical power to a first electrical load and a second electrical load. Upon experiencing a fault, a first circuit element can electrically decouple the first battery and the second battery by opening a circuit provided by the electrical bus, thereby isolating the first battery from the second battery. Next, the battery experiencing the fault can include a second circuit element that can electrically decouple the battery experiencing the fault from a respective electrical load, while the battery isolated from the fault can continue to provide electrical power to components.

Abstract: Techniques for performing multiple simultaneous pose generation for an autonomous vehicle. For instance, a system that navigates the autonomous vehicle can include at least a first component that determines first poses for the autonomous vehicle using at least a first portion of sensor data captured by one or more sensors and a second component that determines second poses for the autonomous vehicle using at least a second portion of the sensor data. The first component may have more computational resources than the second component and determine poses at a different frequency than the second component. The system may generate trajectories for the autonomous vehicle using the first poses when the first component is operating correctly. Additionally, the system may generate trajectories for the autonomous vehicle using the second poses when the first component is not operating correctly.

Abstract: An arrangement of wheels for a bi-directional vehicle may decrease the drag coefficient for the vehicle regardless of a direction of travel of the vehicle. A pair of wheels, each wheel of the pair having a configuration of fins to promote a desired aerodynamic effect, when located at a leading end of the vehicle promotes airflow laterally outboard of the vehicle body. In contrast, the same pair of wheels, when located at a trailing end of the vehicle promotes airflow laterally inboard of the vehicle body.

Abstract: An occupant protection system for a vehicle may include an expandable curtain and/or an expandable bladder configured to be expanded from a stowed state to a deployed state. In the deployed state, the expandable curtain may include first and second sides configured to extend along respective portions of first and second interior sides of the vehicle. The expandable curtain may also include a transverse portion extending between the first and second sides, and the first and second sides, and the transverse portion of the expandable curtain may form a contiguous barrier. The expandable bladder when deployed may be supported by the expandable curtain during contact by an occupant. The occupant protection system may also include a deployment control system configured to cause the expandable curtain and/or the expandable bladder to expand to the deployed state. The occupant protection system may be used in vehicles having a carriage-style seating arrangement.

Abstract: Systems and processes for controlling a autonomous vehicle when the autonomous vehicle detects a disaster may include receiving a sensor signal from a sensor of a autonomous vehicle and determining that the sensor signal corresponds to a disaster definition accessible to the autonomous vehicle. The systems and processes may further include receiving a corroboration of the detected disaster and altering a drive mode of the autonomous vehicle or receiving an indication that the detected disaster was a false positive and returning to a nominal drive mode of the autonomous vehicle.

Abstract: A system for detachably coupling subassemblies to vehicles or other components is discussed herein. The system can include one or more driveshafts and worm drives to drive fasteners to couple the subassembly to the vehicle. The system can enable drive interfaces located in a substantially conventional location (e.g., located vertically on the bottom of the vehicle) to drive fasteners horizontally into the body or other subassembly. In this manner, fasteners can be hidden and to utilize blind holes in the body of the vehicle. The system can be partially disassembled in situ to enable parts replacement and fastener access in the event of a failure. The system can be used in conjunction with a robotic cart to enable subassemblies to be removed from the vehicle for service and repair. A portion of the system can also act as a portion of, or to reinforce, the crash structure of the vehicle.

Abstract: Systems, apparatus, and methods implemented in algorithms, software, firmware, logic, or circuitry may be configured to process data and sensory input in real-time to determine whether an object external to an autonomous vehicle may be a potential collision threat to the autonomous vehicle. The autonomous vehicle may be configured to deploy one or more bladders positioned external to the autonomous vehicle to absorb forces from an impact to the vehicle by the object. A perception system of the vehicle may receive a sensor signal and generate object data associated with the object. A planner system of the vehicle may process the object data to predict an impact time and an impact location on the vehicle. The planner system may cause a drive system of the vehicle to maneuver the vehicle to position an impact-absorbing structure and/or one or more bladders of the vehicle to coincide with the predicted impact location.
