Abstract: A method for vehicle tracking and localization includes receiving, by a controller, odometry data from a sensor of the first vehicle; geospatial data from a Global Positioning System (GPS) device of the first vehicle; inertial data from an inertial measurement unit (IMU) of the first vehicle; estimating an estimated-current location of the first vehicle and an estimated-current trajectory of the first vehicle using the odometry data from the sensor, the geospatial data from the GPS device, and the inertial data from the IMU of the first vehicle; inputting the inertial data into a Bayesian Network to determine a predicted location of the first vehicle and a predicted trajectory of the first vehicle, and updating the Bayesian Network using the estimated-current location and the estimated-current trajectory of the first vehicle using the odometry data and the geospatial data.

Abstract: A method for controlling an automatic liftgate in a vehicle includes detecting a garage door frame of a garage using a front camera or a rear camera mounted on the vehicle, determining a garage height of the garage door frame, determining whether the vehicle has entered the garage, and setting a custom height to which the automatic liftgate can open to the garage height of the garage door frame when the vehicle has entered the garage.

Abstract: A system and method to distinguish between a lane change and a turn of a vehicle as an intended movement of the vehicle based on a driver-initiated motion toward an adjacent lane that is adjacent to a lane occupied by the vehicle include obtaining input from one or more sources. The one or more sources include a sensor system or a communication system. The method also includes processing the input from the one or more sources to obtain indirect information that indicates a direction of travel in the lane adjacent or to obtain direct information specific to a location of the vehicle, determining whether the lane change or the turn is more likely to be the intended movement based on the indirect information or the direct information, and modifying an action of a vehicle system based on the determining whether the lane change or the turn is more likely.

Abstract: Embodiments include methods, systems and computer readable storage medium for determining an attack on a vehicle network and an estimated source location of an attacker. The method includes receiving, by a processor, a plurality of messages. The method further includes analyzing, by the processor, each of the plurality of messages to determine that each of the plurality of messages is suspicious. The method further includes determining, by the processor, that an attack is occurring in response to a determination that multiple messages of the plurality of messages are suspicious. The method further includes localizing, by the processor, a source location for the attack using an angle of arrival associated with each of the plurality of suspicious messages to determine a source intersection. The method further includes notifying, by the processor, one or more vehicles of the attack.

Abstract: A system and method of controlling operation of a host device in real-time, the host device operatively connected to an optical device and a radar device. The optical device is configured to obtain visual data of at least one object. The object is located at an incline, relative to the host device, the incline being characterized by an elevation angle (ϕ) and an azimuth angle (θ). The radar device is configured to obtain radar data, including a radial distance (r) of the object from the host device, the azimuth angle (θ), and a range rate (dr/dt). The controller is programmed to determine a time-to-contact for the host device and the object based at least partially on a 3-D position and 3-D velocity vector. The operation of the host device is controlled based at least partially on the time-to-contact.

Abstract: A method and apparatus for trailer recognition are provided. The method includes detecting a face of a trailer in a first and second image, taken at first and second distances respectively, generating a bounding box around the face of the trailer in the first and second images, determining a first and second set of feature points in the bounding boxes of the first and second images, determining a correspondence between the first set of feature points and the second set of feature points and a correspondence between corners of the bounding boxes and estimating at least one dimension of the trailer by performing a least squares analysis to solve for three-dimensional real world coordinates of the first and second set of features points and the corners of the bounding boxes. The method may assist an operator of a vehicle in aligning the vehicle hitch with a trailer coupler.

Abstract: A method and apparatus for determining ground clearance of a structure are provided. The method includes removing reflection points caused by noise from first reflection point information based on temporal persistency and generating second reflection point information, extracting visual features from an image of a camera based on convolutional neural network, projecting the second reflection point information onto the image, generating region proposals based on the projected second reflection point information and the image, the region proposals indicating potential horizontal structures above a path, detecting stationary horizontal structure above a path based on the generated region proposals, and determining distance between ground and the detected stationary horizontal structure based on the projected reflection point information and the image.

Abstract: Examples of techniques for overlaying on an in-vehicle display road objects associated with potential hazards are disclosed. In one example implementation, a method may include: responsive to detecting a presence of a detected vehicle in proximity to the local vehicle, determining, by a processing device, a position of the detected vehicle, a speed of the detected vehicle, and a time to the local vehicle of the detected vehicle; determining, by the processing device, whether the detected vehicle, in proximity to the local vehicle, represents a potential hazard to the local vehicle based on the position of the detected vehicle, the speed of the detected vehicle, and a time to the local vehicle of the detected vehicle; and responsive to determining that the detected vehicle, in proximity to the local vehicle, represents a potential hazard to the local vehicle, overlaying, by the processing device, a warning indicium on the in-vehicle display.
