Abstract: A driver-fatigue warning system suitable for use in an automated vehicle includes a camera, an alert-device, and a controller. The camera renders an image of a lane-marking and of an object proximate to a host-vehicle. The alert-device is operable to alert an operator of the host-vehicle of driver-fatigue. The controller is in communication with the camera and the alert-device. The controller determines a vehicle-offset of the host-vehicle relative to the lane-marking based on the image. The controller determines an offset-position of the object relative to the lane-marking based on the image. The controller determines that a lane-departure has occurred when the vehicle-offset is less than a deviation-threshold. The controller does not count occurrences of lane-departures when the offset-position is less than an offset-threshold, and activates the alert-device when the count of the occurrences of lane-departures exceeds a crossing-threshold indicative of driver-fatigue.

Abstract: A trailer-detection system includes a radar-sensor, an angle-detector, and a controller. The radar-sensor is used to detect an other-vehicle present in a blind-zone proximate to the host-vehicle. The angle-detector is used to determine a trailer-angle relative to a host-vehicle of a trailer being towed by the host-vehicle. The controller is in communication with the angle-detector and the radar-sensor. The controller is configured to determine a trailer-presence of the trailer based on the radar-signal and the trailer-angle.

Abstract: An automated braking system for use on an automated vehicle includes a braking-actuator, a ranging-sensor, a digital-map, and a controller. The braking-actuator controls movement of a host-vehicle. The ranging-sensor detects a distance, a direction, and an elevation of targets in a field-of-view of the ranging-sensor. The field-of-view includes a roadway. The digital-map defines a travel-route of the host-vehicle and specifies a gradient of the roadway. The controller is in communication with the braking-actuator, the ranging-sensor, and the digital-map. The controller determines that a first-collection of the targets above a horizon is an overpass when the gradient indicates that the roadway descends below the overpass. The controller disregards the first-collection of targets associated with the overpass when the gradient is indicated, and activates the braking-actuator when the controller determines that a second-collection of targets from below the horizon are an obstruction on the travel-route beneath the overpass.

Abstract: This document describes techniques and systems for target of interest selection on roadway ramps. When a host vehicle transitions from a roadway to a ramp, a quantity of lanes of the ramp is determined from a map stored in a driving system of the host vehicle. If there are multiple lanes, then a standard driving scheme may be employed. This standard driving scheme may prioritize a target directly in front of the host vehicle to be a target of interest. However, if the ramp has a single lane, a first target leading the host vehicle, but not necessarily directly in front of the host vehicle is determined to be the target of interest. Driving systems, such as adaptive cruise control, may base driving decisions on the target of interest. By determining the target of interest in this manner, uncertainty due to predictions and complexity of calculations may be reduced.

Abstract: A blind-spot detection system includes an angle-detector, a radar-sensor, and a controller. The angle-sensor is used to determine a trailer-angle relative to a host-vehicle of a trailer being towed by the host-vehicle. The radar-sensor is used to detect an other-vehicle present in a blind-zone proximate to the host-vehicle. The controller is in communication with the angle-detector and the radar-sensor. The controller is configured to adjust a sensing-boundary that defines the blind-zone based on the trailer-angle.

Abstract: A braking-system suitable for use on an automated vehicle 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 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 bottom-edge of the field-of-view and a boundary of a conflict-zone, where the boundary corresponds to a portion of the bottom-edge. The a braking-actuator used to control movement of the host-vehicle. The controller determines a height of the object, determines a distance to the object, determines a range-rate of the object when the object is in the field-of-view, and activates the braking-actuator when an estimated-distance to the object is less than a distance-threshold, the height of the object is greater than a height-threshold, and the object has crossed the boundary and thereby enters the conflict-zone.

Abstract: A navigation-system for use on an automated vehicle includes a perception-sensor and a controller. The perception-sensor detects objects present proximate to a host-vehicle and detects a gradient of an area proximate to the host-vehicle. The controller is in communication with the perception-sensor. The controller is configured to control the host-vehicle. The controller determines a free-space defined as off of a roadway traveled by the host-vehicle, and drives the host-vehicle through the free-space when the gradient of the free-space is less than a slope-threshold and the objects can be traversed.

Abstract: A guidance system, for use on an automated vehicle includes a camera, a vehicle-to-vehicle transceiver, and a controller. The camera detects a lane-marking on a roadway and detects a lead-vehicle traveling ahead of a host-vehicle. The vehicle-to-vehicle transceiver receives a future-waypoint from the lead-vehicle, wherein the future-waypoint defines a future-route of the lead-vehicle along the roadway. The controller is in communication with the camera and the vehicle-to-vehicle transceiver. The controller determines a projected-path for the host-vehicle based on the lane-marking. The controller also determines a lead-path of the lead-vehicle based on the camera. The controller steers the host-vehicle according to the lead-path when the lane-marking is not detected and the lead-path corresponds to the projected-path. The controller steers the host-vehicle according to the projected-path while the lane-marking is not detected and the future-waypoint does not correspond to the projected-path.

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.
