Abstract: An autonomous vehicle includes a detection system for identifying the presence changes in wind incident on the autonomous vehicle, particularly wind gusts. The detection system may include one or more wind sensors, particularly those configured to detect wind incident on the vehicle from a direction that is transverse or perpendicular to the direction of motion of the autonomous vehicle. Additionally, systems may be present that correlate the detected wind gusts to changes in the behavior of the autonomous vehicle. The autonomous vehicle may react to the detected wind gusts by altering the vehicle's trajectory, by stopping the vehicle, or by communicating with a control center for further instructions.

Abstract: An integrated housing assembly mountable on a roof of a vehicle, such as a semi-trailer truck. The integrated housing assembly includes a main enclosure that includes four sides, a top panel, and a bottom panel. One of the four sides is a front panel that is inclined towards the ground. The main enclosure includes one or more cavities. A front panel of the integrated housing assembly includes one or more openings to allow cameras or sensors to be placed within the one or more cavities and behind the one or more opening. The cameras or sensors cameras can be clamped at a downward angle within multiple lock apparatus. The angled front panel and the inclined cameras or sensors within the lock apparatus allow the cameras or sensors to obtain images or sensor data from one or more regions of interest at some distance from the front of the vehicle.

Abstract: A system comprises an autonomous vehicle (AV) and a control device operably coupled with the AV. The control device receives, from an operation server, a command to navigate the AV to avoid an expected road condition. The control device receives, from sensors of the AV, sensor data comprising location coordinates of a plurality of objects ahead of the AV. The control device determines whether at least one object from the plurality of objects impedes performing the command. In response to determining that at least one object impedes performing the command, the control device updates the command, such that the updated command comprises one or more navigation instructions to avoid the at least one object while performing the command. The control device navigates the AV according to the updated command.
