Abstract: A system comprises a headlight mounted on an autonomous vehicle. The headlight is configured to illuminate at least a portion of a road the autonomous vehicle is on. The system further comprises a control device associated with the autonomous vehicle. The processor obtains information about an environment around the autonomous vehicle. The processor determines that at least a portion of the road should be illuminated if the information indicates that an illumination level of the portion of the road is less than a threshold illumination level. The processor adjusts the headlight to illuminate at least the portion of the road in response to determining that at least the portion of the road should be illuminated.

Abstract: Disclosed are devices, systems and methods for compensating radar measurements of a vehicle. One exemplary method includes generating a set of velocity hypotheses of a target object based on a first measurement data obtained from sensors mounted on the vehicle; generating cluster velocity estimates by applying a clustering algorithm to a second measurement data obtained from the sensors; and providing one or more selected velocity hypotheses from the set of velocity hypothesis as compensated radar measurements for the target object based on the cluster velocity estimates.

Abstract: A gateway processor coordinates communication among an autonomous vehicle components boundary domain, a vehicle boundary domain, and an oversight server. The gateway processor receives a message from the oversight server. The gateway processor determines a priority level, a domain tag data, and destination data associated with the message. The priority level indicates a scheduling requirement associated with the message. The domain tag data indicates that the message is associated with a particular domain from among the autonomous vehicle components boundary domain, the vehicle components boundary domain, or the security domain. The destination data indicates that the message is designated to a particular component within the particular domain. In response, the gateway processor schedules the message to be transmitted to the particular domain. The gateway processor routes the message to the particular component.

Abstract: A mobile terminal system includes equipment used to establish a terminal site with at least one landing pad sized and shaped to accommodate an autonomous vehicle of a fleet. A control subsystem determines that an autonomous vehicle of the fleet is in-bound to the established terminal site. After determining the in-bound autonomous vehicle, landing instructions are determined that indicate a landing pad in which the in-bound autonomous vehicle is to stop and a route that the in-bound autonomous vehicle is to travel along to reach the landing pad. The landing instructions are provided to the in-bound autonomous vehicle. The landing instructions cause the in-bound autonomous vehicle to travel along the route to the landing pad.

Abstract: The disclosed technology enables an in-vehicle control computer located in an autonomous vehicle to control torque applied by an engine in the autonomous vehicle. An example method of autonomous driving operation includes sending, by a computer located on the vehicle, instructions to one or more devices located on the vehicle that cause the vehicle to perform autonomous driving related operations in accordance with the instructions, where the sending the instructions includes sending a set of torque related values over time to control an engine located in the vehicle, where the set of torque related values are not converted to control parameters indicative of positions associated with an accelerator pedal located in the vehicle; receiving an indication that indicates that the accelerator pedal is depressed from an undepressed position; and causing, in response to the receiving the indication, the vehicle to not perform additional autonomous driving related operations.

Abstract: A power management system is disclosed for managing power in a vehicle. The system may include a power distribution unit (PDU) communicably coupled to a power controller unit located in the vehicle. The power controller unit comprises a microcontroller configured to: receive, from the PDU, a temperature value that indicates a temperature of the PDU, one or more voltage values from the one or more voltage sensors, or one or more current values from the one or more current sensors, perform a determination that the temperature value, the one or more voltage values, or the one or more current values are below one or more of their respective pre-determined threshold values, and send, after the determination, a health status message to a computer located in the vehicle, where the health status message indicates that the PDU is operating in a safe operating condition.

Abstract: Systems and methods for detecting physical infrastructure related to navigation of an autonomous vehicle are disclosed. In one aspect, the autonomous vehicle includes a perception sensor configured to generate perception data, a non-transitory computer readable medium, and a processor. The processor is configured to determine a minimal risk condition (MRC) maneuver for the autonomous vehicle to execute, identify a safe zone in which the autonomous vehicle is able to execute the MRC maneuver by coming to a stop based on the perception data, identify one or more exclusion zones within the safe zone based on the perception data, and control the autonomous vehicle to execute the MRC maneuver including stopping outside of the exclusion zone.

Abstract: A high precision digital map is pre-developed and stored in a memory of an in-vehicle control computer on an autonomous vehicle. The digital map is updated by the in-vehicle control computer with detected roadway data that is a fusion of roadway perception data from at least one perception sensor on the autonomous vehicle and real time GPS signal from at least one GPS receiving devices on the autonomous vehicle. The updated digital map is transferred to a remote oversight system via a network communication subsystem, and the oversight system distributes the updated digital map to other autonomous vehicles connected over the network communication subsystem.

Abstract: A system includes an autonomous vehicle and an oversight server. The oversight server obtain sensor data from the autonomous vehicle. The sensor data may include a location of the autonomous vehicle. The oversight server determines that one or more criteria apply to the autonomous vehicle based on the sensor data. The one or more criteria includes a geofence area, a particular time window, and a credential associated with a third party. The oversight server grants remote access to the autonomous vehicle in response to determining that the one or more criteria apply to the autonomous vehicle.
