Abstract: A vehicle is provided that may combine multiple estimates of an environment into a consolidated estimate. The vehicle may receive first data indicative of the region of interest in an environment from a sensor of the vehicle. The first data may include a first accuracy value and a first estimate of the region of interest. The vehicle may also receive second data indicative of the region of interest in the environment, and the second data may include a second accuracy value and a second estimate of the region of interest. Based on the first data and the second data, the vehicle may combine the first estimate of the region of interest and the second estimate of the region of interest.

Abstract: A method and apparatus are provided for optimizing one or more object detection parameters used by an autonomous vehicle to detect objects in images. The autonomous vehicle may capture the images using one or more sensors. The autonomous vehicle may then determine object labels and their corresponding object label parameters for the detected objects. The captured images and the object label parameters may be communicated to an object identification server. The object identification server may request that one or more reviewers identify objects in the captured images. The object identification server may then compare the identification of objects by reviewers with the identification of objects by the autonomous vehicle. Depending on the results of the comparison, the object identification server may recommend or perform the optimization of one or more of the object detection parameters.

Abstract: Disclosed herein are systems and methods for providing supplemental identification abilities to an autonomous vehicle system. The sensor unit of the vehicle may be configured to receive data indicating an environment of the vehicle, while the control system may be configured to operate the vehicle. The vehicle may also include a processing unit configured to analyze the data indicating the environment to determine at least one object having a detection confidence below a threshold. Based on the at least one object having a detection confidence below a threshold, the processor may communicate at least a subset of the data indicating the environment for further processing. The vehicle is also configured to receive an indication of an object confirmation of the subset of the data. Based on the object confirmation of the subset of the data, the processor may alter the control of the vehicle by the control system.

Abstract: An autonomous vehicle detects a tailgating vehicle and uses various response mechanisms. 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 responds 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. In this regard, 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: The present disclosure is related to an antenna system for a vehicle, such as a vehicle that has a non-metallic roof. The antenna system includes two metallic supports coupled to the roof. Additionally, the antenna system includes a first MIMO antenna pair. A first antenna of the first MIMO antenna pair is coupled to a first support of the two metallic supports, and a second antenna of the first MIMO antenna pair is coupled to a second support of the two metallic supports. The antenna system further includes a second MIMO antenna pair. A first antenna of the second MIMO antenna pair is coupled to the first support of the two metallic supports, and a second antenna of the second MIMO antenna pair is coupled to the second support of the two metallic supports. Yet further, the two metallic supports of the antenna system are physically separated from each other.

Abstract: A vehicle configured to operate in an autonomous mode is provided. The vehicle is configured to obtain an indication of a final destination, and, if the final destination is not on a pre-approved road for travel by the vehicle, the vehicle is configured to determine a route from the vehicle's current location to an intermediary destination. The vehicle is further configured to determine a means for the vehicle user to reach the final destination from the intermediate destination.
Abstract: A system and method is provided of providing recommendations to a user of a vehicle. In one aspect, the vehicle navigates autonomously and the sensors provide information that is based on the location of the vehicle and output from sensors directed to the environment surrounding the vehicle. In further aspects, both current and previous sensor data is used to make the recommendation, as well as data based on the sensors of other vehicles.

Abstract: An example method of fabricating a waveguide antenna may involve providing a first metal layer with waveguide channels formed therein. The method may also involve selecting at least one coupling surface on the first metal layer that is proximate to at least edges of the waveguide channels. The method may also involve removing respective oxidation layers from second and third metal layers. The method may also involve providing, to the selected at least one coupling surface, a fusible metal material and a reactive metal foil between surfaces of the first and second metal layers and between surfaces of the first and third metal layers. The method may also involve coupling the layers together by igniting the reactive metal foil so as to locally provide heat to the surfaces of the layers and melt the fusible metal material, and then cooling the melted fusible metal material.
Abstract: A method and apparatus are provided for determining the location of a vehicle. According to one aspect the method and apparatus the movements of motor rotors in a vehicle are monitored and used to determine speed, travel distance and/or travel path of a vehicle may be determined. Using various navigation techniques, the distance and travel path may then be used to determine the vehicle's location. Furthermore, movements of the motor rotors may also be used to report the positions of the steering and drive systems for the purpose of informing the vehicle controller as a method of feedback.

Abstract: The invention relates to collecting different images using different camera parameters. As an example, a single camera may capture two different types of images: a dark exposure for light emitting objects and a normal exposure for passive objects. The camera may first capture an image. This first image may be processed to determine the ideal camera settings for capturing the average intensity of the environment. Fixed offset values may be added to these ideal camera settings and the dark exposure may be captured. The ideal camera settings are then used to capture a normal exposure, which in turn may be processed to determine new ideal camera settings. Again, the fixed offset values may be added to the new ideal camera settings and a dark exposure is captured. This process may repeat continuously and periodically, and the resulting images may be processed to identify emissive and passive objects.
