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: 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.

Abstract: A braking system suitable for use on an automated vehicle includes a ranging-sensor, a braking-actuator, and a controller. The ranging-sensor detects reflections indicative of objects present in a field-of-view proximate to a host-vehicle. The braking-actuator controls movement of the host-vehicle. The controller is in communication with the ranging-sensor and the braking-actuator. The controller determines a region-of-interest within the field-of-view and defines an occupancy-grid that segregates the field-of-view into an array of grid-cells. The controller further determines a repeatability-of-detection of each of the grid-cells based on reflections detected by the ranging-sensor. The controller further determines that a rigid-object is present in the field-of-view when each of a string of the grid-cells are characterized by the repeatability-of-detection greater than a repeatability-threshold. The controller activates the braking-actuator when the string intersects the region-of-interest.

Abstract: A trailer-detection system includes a radar sensor, an angle detector, 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 trailer towed by a host-vehicle. The angle-detector is used to determine a trailer angle relative to the host vehicle of the trailer towed by the host vehicle. The camera is used to detect a lane marking of a roadway traveled by the host vehicle and trailer. The controller is in communication with the radar sensor, the angle detector, and the camera. The controller is configured to determine when the trailer is departing from a travel lane of the roadway based on the radar signal, the trailer angle, and the lane marking.

Abstract: A trailer detection system is configured to determine a presence of a trailer towed by a host-vehicle. The system includes a camera and a controller. The camera is used to capture an image of an area behind a host vehicle. The controller is in communication with the camera. The controller is used to detect a position of an edge in the image and determine that the edge is associated with a trailer towed by the host vehicle when the position of the edge moves less than a movement threshold.

Abstract: A driver-fatigue warning system includes a speed-limit-detection-means, a speed-sensor, an alert-device, and a controller. The speed-limit-detection-means detects a speed-limit of a roadway traveled by a host-vehicle. The speed-sensor detects a speed of the 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 speed-limit-detection-means, the speed-sensor, and the alert-device. The controller determines a change of the speed-limit of the roadway based on the speed-limit-detection-means. The controller determines that a speed-change has occurred based on the speed-sensor when a variation in the speed is greater than a variation-threshold. The controller does not increment a count of occurrences of the speed-change when the speed-change correlates with the change of the speed-limit, and activates the alert-device when the count of occurrences of the speed-change exceeds a change-threshold indicative of driver-fatigue.

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 cross traffic detection system suitable for use on an automated vehicle includes an object-detector, an alert-device, and a controller. The object detector is used to determine locations of moving objects relative to a host vehicle. The alert device is used to alert an operator of the host vehicle to the location of the moving objects. The controller is in communication with the object detector and the alert device. The controller determines a first trail of a first moving object based on the locations of the first moving object, and determines a road model based on a polynomial of the first trail. The controller also determines a second trail of a second moving object, assigns a lane number to the second moving object based on the road model, and activates the alert device when the path of the second moving object resides in the lane-number overlain by a conflict zone.

Abstract: A warning system for an automated vehicle includes an object-detector, a location-detector, a transceiver, and a controller. The object-detector is used to determine a separation-distance to a target-vehicle from a host-vehicle. The location-detector is used to provide global-positioning-system-coordinates (GPS-coordinates) of the target-vehicle. The transceiver is used to transmit a proximity-warning to the target-vehicle. The controller is in communication with the object-detector, the location-detector, and the transceiver. The controller is configured to operate the transceiver to transmit the proximity-warning when the separation-distance between the host-vehicle and the target-vehicle is less than a distance-threshold. The proximity-warning includes the GPS-coordinates of the target-vehicle and the separation-distance.
