摘要： 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.

摘要： 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.

摘要： Systems and methods for general driving behavior of an autonomous vehicle are disclosed. In one aspect, an autonomous vehicle includes a trailer, at least one perception sensor, a non-transitory computer readable medium, and a processor. The processor is configured to estimate a grade of the roadway based on the perception data, provide a first control input to the autonomous vehicle based on the grade of the roadway, determine a response of the autonomous vehicle to the first control input based on the perception data, estimate a trailer load of the trailer based on the response of the autonomous vehicle to the first control input, and provide a second control input to the autonomous vehicle based on the grade of the roadway and the trailer load.

摘要： A control device associated with an autonomous vehicle receives sensor data and detects that the autonomous vehicle is approaching a railroad crossing based on the sensor data. The control device determines that the railroad crossing is closed from the sensor data. The control device determines one or more re-routing options from map data. The control device determines whether at least one re-routing option reaches a predetermined destination of the autonomous vehicle. In response to determining that the at least one re-routing option reaches the predetermined destination, the control device selects a particular re-routing option based at least on determining that the autonomous vehicle is able to travel according to the particular re-routing option autonomously. The control device instructs the autonomous vehicle to re-route according to the particular re-routing option.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： A control device associated with an autonomous vehicle receives sensor data and detects that the autonomous vehicle is approaching a railroad crossing based on the sensor data. The control device determines a target lane to travel while crossing the railroad. The target lane is a lane that has available space with at least a length of the autonomous vehicle on the other side of the railroad as opposed to a side of the railroad where the autonomous vehicle is currently traveling. The control device instructs the autonomous vehicle to travel on the target lane. The control device determines that a train is approaching the railroad crossing and waits for the train to pass the railroad crossing. The control device determines that the train has passed the railroad crossing. The control device instructs the autonomous vehicle to cross the railroad.
