Abstract: In a method for exchanging navigation data between a portable device and a head unit of a vehicle, implemented in a portable device that includes one or more processors executing a navigation service application and a companion application, the navigation service application sends a destination to a navigation server, and receives first navigation data from the navigation server. The first navigation data describes at least one of a plurality of steps for navigating between a source and the destination. A companion application invokes a navigation application programming interface (API) of the navigation service application, at by using a syntax and a list of parameters specific to the navigation API to obtain, from the navigation service application, the first navigation data, and sends the first navigation data to the head unit to cause the head unit to display navigation information indicating at least the one of the plurality of navigation steps.
Abstract: A rotary locking joint that has zero backlash is provided to secure a camera mast mounted on a vehicle in a deployed position. The joint is passive to lock while being easily releasable. The joint prevents rotation of the mast in one direction, with a hard stop element that prevents further rotation of the mast in the opposite direction. The locking joint includes a pawl member configured to rotate about a pawl rotation axis. The pawl member is maintained in place in the locked position via a torsion spring to ensure contact with a base portion of the mast. To release the joint, the pawl member is rotated in the opposite direction to remove a geometry interference condition. A sensor is arranged to detect whether the pawl member is in an unlocked position relative to the mast.

Abstract: An apparatus and method are disclosed for performing loop closing on one or more paths to be optimized. The paths may include poses associated with imagery obtained by a vehicle. The apparatus may identify candidate intersections from the paths based on their proximity, and may further determine relative poses from the poses of the paths using structure-from-motion techniques. The apparatus may then apply a partitioning schema to the paths to be optimized to obtain individual partition cells. The partition cells may then be sent to one or more client devices for optimizing the paths included in the partition cells. When the apparatus receives a set of optimized paths from the client devices, the apparatus may re-partition the paths to be optimized to ensure that non-optimized portions of paths are optimized.

Abstract: Embodiments described herein may relate to methods and systems for supplying auxiliary power to an unmanned aerial vehicle (UAV) with different flight modes. In particular, the system may determine that a UAV is operating in a first flight mode. Responsively, the system may cause the UAV to draw power from a first power source at a first power level while operating in the first flight mode. Subsequently, the system may determine that the UAV switched from operating in the first flight mode to operating in a second flight mode. Responsively, the system may cause the UAV, while operating in the second flight mode, to continue drawing power from the first power source at the first power level and draw power from a second power source at a second power level, where the UAV consumes power at a higher rate during the second flight mode than during the first flight mode.

Abstract: Methods and systems for alignment of light detection and ranging (LIDAR) data are described. In some examples, a computing device of a vehicle may be configured to compare a three-dimensional (3D) point cloud to a reference 3D point cloud to detect obstacles on a road. However, in examples, the 3D point cloud and the reference 3D point cloud may be misaligned. To align the 3D point cloud with the reference 3D point cloud, the computing device may be configured to determine a planar feature in the 3D point cloud of the road and a corresponding planar feature in the reference 3D point cloud. Further, the computing device may be configured to determine, based on comparison of the planar feature to the corresponding planar feature, a transform. The computing device may be configured to apply the transform to align the 3D point cloud with the reference 3D point cloud.

Abstract: An unmanned aerial vehicle (UAV) is disclosed that includes a retractable payload delivery system. The payload delivery system can lower a payload to the ground using an assembly that secures the payload during descent and releases the payload upon reaching the ground. The assembly can also include a bystander communication module for generating cues for bystander perception. While the assembly securing the payload is being lowered from the UAV, the bystander communication module can generate an avoidance cue indicating that bystanders should avoid interference with the assembly. The assembly also includes sensors that generate data used, at least in part, to determine when the descending assembly is at or near the ground, at which point the assembly releases the payload. The bystander communication module can then cease the avoidance cue and the UAV can retract the assembly.

Abstract: An autonomous vehicle detects a tailgating vehicle and uses various response mechanisms. For example, a vehicle is identified as a tailgater based on whether its characteristics meet a variable threshold. When the autonomous vehicle is traveling at slower speeds, the threshold is defined in distance. When the autonomous vehicle is traveling at faster speeds, the threshold is defined in time. The autonomous vehicle may respond to the tailgater by modifying its driving behavior. In one example, the autonomous vehicle adjusts a headway buffer (defined in time) from another vehicle in front of the autonomous vehicle. For example, if the tailgater is T seconds too close to the autonomous vehicle, the autonomous vehicle increases the headway buffer to the vehicle in front of it by some amount relative to T.

Abstract: Implementations are directed to causing a computing device to transmit an audio data stream, via a communication channel, to a vehicle computing device of a vehicle. Various implementations include one or more vehicle speakers driven by the vehicle computing device to render audible output. Additionally or alternatively, various implementations include determining whether the audible output is captured by at least one microphone of a vehicle interface device within the vehicle. In many implementations, the vehicle interface device is communicatively coupled to the computing device.
Abstract: To reduce the effects of traffic jams, a traffic reduction system identifies road segments having more a threshold amount of traffic. The traffic reduction system also receives an indication of a current location of a client device operating in a vehicle and compares the current location to the locations of the identified road segments to determine whether the vehicle is on or approaching the road segment. If the vehicle is on or approaching the road segment, the traffic reduction system determines a target speed for the vehicle to maintain an equal distance between the vehicle and the vehicle in front of the vehicle and the vehicle and the vehicle behind the vehicle. The traffic reduction system then provides the target speed to the client device for display on a user interface. By maintaining equal distances between vehicles in front of and behind each other, the amount of traffic dissipates.
Abstract: Methods and systems for implementing steering-based scrub braking are described. A computing device or system assisting in the control of a vehicle may be configured to make a determination to reduce a speed of the vehicle or enhance the stability of a vehicle that is traveling in a given direction. The computing device may provide instructions to turn a pair of wheels or any combination of wheels of the vehicle in a direction away from parallel to the given direction in which the vehicle is traveling and in opposite directions to each other so as to reduce the speed of the vehicle. In an example, the computing device may estimate a range to execute speed reduction of the vehicle.
