Abstract: Systems and methods for managing environmental conditions for an autonomous vehicle are disclosed. In one aspect, an autonomous vehicle includes a perception sensor configured to generate perception data indicative of a condition of the environment, a network communication transceiver configured to communicate with an oversight system and an external weather condition source, a non-transitory computer readable medium, and a processor. The processor is configured to: receive the perception data from the at least one perception sensor, receive an indication of current weather conditions from the external weather condition source, determine a current environmental condition severity level from a plurality of severity levels based on the perception data and the indication of current weather conditions, modify one or more driving parameters that that govern a range of actions that can be autonomously executed by the autonomous vehicle, and navigate the autonomous vehicle based on the modified driving parameters.

Abstract: A control device associated with an autonomous vehicle detects that a person is altering traffic on a road using a hand signal. The control device determines an interpretation of the hand signal. The control device determines a proposed trajectory according to the interpretation of the hand signal. The control device transmits the proposed trajectory to an oversight server. The oversight server determines whether the hand signal is in use to alter the traffic. The oversight server also determines whether the proposed trajectory causes the autonomous vehicle to go out of a pre-mapped area where the autonomous vehicle is able to autonomously travel. In response to determining that the hand signal is in use and that the proposed trajectory does not cause the autonomous vehicle to go out of the pre-mapped area, the oversight server transmits an instruction that indicates to perform the proposed trajectory to the control device.

Abstract: An autonomous vehicle (AV) includes features that allows the AV to comply with applicable regulations and statutes for performing safe driving operation. An example method includes detecting that a group of motorcycles is operating on a roadway on which the AV is located. The group of motorcycles are each located within a pre-determined distance away from one another. The method further includes determining an aggregate footprint area that surrounds respective locations of the group of motorcycles. The method further includes causing navigation of the autonomous vehicle that avoids penetration of the aggregate footprint area based on transmitting navigation instructions to one or more subsystems of the autonomous vehicle.

Abstract: Systems and methods for situational behavior of an autonomous vehicle are disclosed. In one aspect, an autonomous vehicle includes at least one perception sensor configured to generate perception data indicative of at least one other vehicle on a roadway, a non-transitory computer readable medium, and a processor. The processor is configured to determine that the other vehicle is violating one or more rules of the roadway based on the perception data, tag the other vehicle as a non-compliant driver, and modify control of the autonomous vehicle in response to tagging the other vehicle as a non-compliant driver.

Abstract: A lead autonomous vehicle (AV) includes a sensor configured to observe a field of view in front of the lead AV. Following AVs are on the same road behind the lead AV. A processor of the lead AV is configured to detect a road closure. The processor overrides driving instructions of the lead AV, such that the lead AV is stopped at first location coordinates. The processor sends a first message to an operation server, indicating that the road closure is detected. The operation server update the first portion of the map data, reflecting the road closure. The operation server determines whether re-routing is possible for each AV. If re-routing is possible is possible for that AV, the operation server sends re-routing instructions to the AV. If re-routing is not possible is possible for that AV, the operation server sends pulling over instructions to the AV.

Abstract: A lead autonomous vehicle (AV) includes a sensor configured to observe a field of view in front of the lead AV. Following AVs are on the same road behind the lead AV. A processor of the lead AV is configured to detect a road structural change on the particular road. The processor updates driving instructions of the lead AV to navigate through the structural change using driving instructions related to the structural change. The processor sends a first message to the operation server indicating that the structural change is detected. The operation server updates the first portion of the map data, reflecting the structural change. The operation server sends the updated map data to the one or more following AVs.

Abstract: A control device associated with an autonomous vehicle detects that a construction worker is altering traffic on a road using a construction zone-related hand signal to divert the traffic from a construction site. The control device determines an interpretation of the construction zone-related hand signal. The control device determines a proposed trajectory for the autonomous vehicle according to the interpretation of the construction zone-related hand signal. In certain embodiments, the control device may navigate the autonomous vehicle according to the interpretation of the construction zone-related hand signal. In certain embodiments, the control device may transmit the proposed trajectory to an oversight server for confirmation. In certain embodiments, the oversight may confirm or override the proposed trajectory.

Abstract: A lead autonomous vehicle (AV) includes a sensor configured to observe a field of view in front of the lead AV. Following AVs are on the same road behind the lead AV. A processor of the lead AV is configured to detect a construction zone. The processor sends a first message to an operation server, indicating that the construction zone is detected. The processor updates driving instructions of the lead AV to navigate around the construction zone. While navigating around the construction zone, the processor sends sensor data associated with the construction zone to the operation server. The operation server determines an extent of the construction zone. If the operation server determines that the construction zone is extensive, it sends re-routing instructions to the AVs. If the operation server determines that the construction zone is not extensive, it sends instructions to navigate around the construction zone to the AVs.

Abstract: A control subsystem, method, computer program product and autonomous vehicle are provided to respond to an unknown object on a carriageway along which an autonomous vehicle is to travel. In this regard, sensor data is received from at least one vehicle sensor. The sensor data includes location coordinates of the object on the carriageway. The sensor data is evaluated to determine whether the object is known or unknown. If unknown, the size of the object is determined and a motion plan is defined for the autonomous vehicle depending upon the size of the object and the location coordinates of the object relative to the autonomous vehicle. The motion plan that is defined is dependent upon the size of the object with different motion plans being defined for differently sized objects. Driving instructions for the autonomous vehicle are then updated based upon the motion plan that is defined.
