Abstract: A navigation system includes a digital-map, a global-positioning-system receiver, and one or more controller-circuits. The digital-map includes a record of global-positioning-system dead-zones. The global-positioning-system receiver indicates a position of a host-vehicle on the digital-map. The one or more controller-circuits are in communication with the global-positioning-system receiver and the digital-map. The one or more controller-circuits are configured to steer the host-vehicle. The one or more controller-circuits determine the position of the host-vehicle relative to the global-positioning-system dead-zone and determining whether a travel-path for the host-vehicle includes a lane-change to a desired-lane. In accordance with the determination by the one or more controller-circuits that the travel-path includes a lane-change and that the host-vehicle is outside of the global-positioning-system dead-zone, the one or more controller-circuits steer the host-vehicle to the desired-lane.

Abstract: A trailer-detection system includes a radar-sensor, a camera, and a controller. The radar-sensor is used to determine a range, and an azimuth-angle, of a radar-signal reflected by a feature of trailer towed by a host-vehicle. The camera is used to capture an image of the trailer. The controller is in communication with the radar-sensor and the camera. The controller is configured to determine a position in the image of a viewable-feature of the trailer, determine a trailer-width and a trailer-height of the trailer based on the position and a range and azimuth-angle to the viewable-feature indicated by the radar-sensor, and optionally determine the trailer-length based on the range and azimuth-angle of the radar-signal reflected by a hidden-feature.

Abstract: An automated speed control system includes a ranging-sensor, a camera, and a controller. The ranging-sensor detects a lead-speed of a lead-vehicle traveling ahead of a host-vehicle. The camera detects an object in a field-of-view. The controller is in communication with the ranging-sensor and the camera. The controller is operable to control the host-vehicle. The controller determines a change in the lead-speed based on the ranging-sensor. The controller reduces a host-speed of the host-vehicle when the lead-speed is decreasing, no object is detected by the camera, and while a portion of the field-of-view is obscured by the lead-vehicle.

Abstract: An object-detection system suitable for use on an autonomous vehicle includes a camera, a radar-sensor, and a controller. The camera detects a travel-lane of a roadway traveled by a host-vehicle. The radar-sensor detects targets in a field-of-view of the radar-sensor. The field-of-view includes the roadway, wherein the roadway defines a boundary of the roadway detected by the radar-sensor. The controller is in communication with the camera and the radar-sensor. The controller determines that a collection of targets is a stationary-object that defines a line. The controller classifies the stationary-object as an overpass when the line extends beyond the boundary of the roadway. The controller classifies the stationary-object as an impediment when the line overlays a portion of the travel-lane traveled by the host-vehicle and does not extend beyond the boundary of the roadway.

Abstract: A lane centering system for a vehicle includes a light detection and ranging (LIDAR) system configured to (i) emit light pulses towards raised pavement markers on a road along which the vehicle is traveling and (ii) receive light pulses reflected by the raised pavement markers that collectively form LIDAR point cloud data, and a controller configured to detect a set of lane lines defining one or more lanes on the road based on the LIDAR point cloud data, based on at least the detected set of lane lines; generate a polynomial curve corresponding to a center of a lane in which the vehicle is traveling, and control steering of the vehicle based on the polynomial curve to keep the vehicle centered within the lane.

Abstract: A lane assignment system includes a digital-map, a ranging-sensor, and one or more controller-circuits. The digital-map indicates a position of a host-vehicle traveling in a travel-lane on a roadway. The ranging sensor detects a lateral-distance to an other-vehicle traveling on the roadway proximate the host-vehicle. The one or more controller-circuits are in communication with the digital-map and the ranging-sensor. The one or more controller-circuits determine a lateral-variation of the lateral-distance, determine whether the lateral-variation is greater than a dynamic-threshold, determine whether a second-lane exists beyond a first-lane based on the digital-map, determine that the other-vehicle is traveling in the first-lane, and operate the host-vehicle in accordance with the other-vehicle traveling in the first-lane.

Abstract: In accordance with one embodiment, a braking-system suitable for use on an automated vehicle is provided. The braking-system includes a ranging-sensor, a braking-actuator, and a controller in communication with the ranging-sensor and the braking-actuator. The ranging-sensor is used to detect a range-rate, a range, and a direction of an object proximate to a host-vehicle when the object resides in a field-of-view of the ranging-sensor. The field-of-view defines a conflict-zone and a conflict-buffer separate from the conflict-zone. The braking-actuator is used to control movement of the host-vehicle. The controller determines a trail of the object based on the range and the direction. The controller further classifies the object as slow-moving based on a rate-threshold. The controller further determines a tangent-vector based on the trail. The controller activates the braking-actuator when the object is slow-moving, the object is detected within the conflict-buffer, and the tangent-vector intersects the conflict-zone.
