    Abstract: A system and method of controlling auxiliary vehicle functions via one or more touchpads on the vehicle steering wheel is disclosed. In response to receiving a user input at one of the touchpads, the vehicle performs a corresponding action depending on the region of the touchpad in which the input was received and the context in which the vehicle is currently operating. During operation, the vehicle displays, on a display screen of the vehicle (e.g., the HUD), a contextual control image indicating which actions will be performed in response to various inputs entered at one or more of the touch pads on the steering wheel. In this way, the steering wheel can accept an input for a variety of auxiliary functions.

    Abstract: Generally described, one or more aspects of the present application correspond to techniques for dynamic management of the timing of data transfer between a connected vehicle and a remote computing system. For example, during navigation a connected vehicle may switch between connections to a number of different networks, each having different parameters (cost, bandwidth, quality, etc.). The disclosed techniques can use inputs including vehicle location, available networks, and data transfer timing requirements to optimize data transfer with respect to one or more of these parameters.

    Abstract: Systems and methods for providing visual assistance during an autonomous driving maneuver are disclosed. The vehicle includes one or more sensors, one or more processors, and a memory including instructions, which when executed by the one or more processors, cause the one or more processors to perform a method that includes determining available positions of the vehicle based on sensor data received from the one or more sensors, receiving input indicating a selected position of the available positions of the vehicle, providing instructions to autonomously maneuver the vehicle to the selected position based on the sensor data and the selected position, the autonomous maneuver including one or more steps, and providing for display an autonomous driving maneuver user interface including a graphical indicator of a current step of the autonomous maneuver and a graphical indicator of a destination position of the current step.

    Abstract: Battery module communication system with improved enclosure sealing is disclosed. When applied to an electric vehicle, a battery data communication system disclosed herein includes module enclosures having partial transformers, such as coils, contained inside the enclosures having inter-module interfaces. The inter-module interfaces can engage with one another to form transformers without the module enclosures having wire holes to connect data communication circuits contained in the respective module enclosures.

    Abstract: Features of a vehicle navigation system are discussed in this disclosure. In particular, systems and methods for identifying glare-prone areas and establishing a route that avoids one or more of the identified glare-prone areas that are determined to be likely to degrade visibility of an environment outside of the vehicle. In some embodiments, the navigation system can be configured to calculate the likely duration of a trip and then based on sun angle data identify locations where glare is likely to be problematic. In some embodiments, the navigation system can also be configured to choose routes that avoid bright sources of light that could adversely affect visual acuity at night.

    Abstract: The present invention is related to systems and methods for detecting an occluded object based on the shadow of the occluded object. In some examples, a vehicle of the present invention can capture one or more images while operating in an autonomous driving mode, and detecting shadow items within the captured image. In response to detecting a shadow item moving towards the direction of vehicle travel, the vehicle can reduce its speed to avoid a collision, should an occluded object enter the road. The shadow can be detected using image segmentation or a classifier trained using convolutional neural networks or another suitable algorithm, for example.

    Abstract: Improved processing of sensor data (e.g., LiDAR data) can be used to distinguish between free space and objects/hazards. Autonomous vehicles can use such information for performing autonomous driving and/or parking operations. LiDAR data can include a plurality of range measurements (e.g., forming a 3D point cloud). Each of the range measurements can correspond to a respective LiDAR channel and azimuth angle. The processing of LiDAR data can include identifying one or more paths as candidate ground paths based on one or more path criteria. The processing of LiDAR data can also include identifying one or more of the plurality of range measurements as ground points or non-ground points based on the one or more paths identified as candidate ground paths and based on one or more point criteria.

    Abstract: The present disclosure is related to enhanced vehicle localization using speed bump detection. In some examples, a vehicle of the present disclosure can estimate its location using GNSS and/or dead reckoning techniques. However, especially in scenarios where GNSS reception is poor, the uncertainty in the vehicle's location can be too large to accurately control the vehicle in a fully- or partially-autonomous driving mode. To reduce uncertainty in the vehicle's location, the vehicle can locate one or more features included in map information received by or stored on the vehicle. In some embodiments, a speed bump is included in the map information. The speed bump can be detected by one or more sensors, such as a motion sensor or one or more suspension level sensors, of the vehicle. The vehicle can determine its location using the detected position of the speed bump and the map information.
