    Abstract: A ground-classifier system that classifies ground-cover proximate to an automated vehicle includes a lidar, a camera, and a controller. The lidar that detects a point-cloud of a field-of-view. The camera that renders an image of the field-of-view. The controller is configured to define a lidar-grid that segregates the point-cloud into an array of patches, and define a camera-grid that segregates the image into an array of cells. The point-cloud and the image are aligned such that a patch is aligned with a cell. A patch is determined to be ground when the height is less than a height-threshold. The controller is configured to determine a lidar-characteristic of cloud-points within the patch, determine a camera-characteristic of pixels within the cell, and determine a classification of the patch when the patch is determined to be ground, wherein the classification of the patch is determined based on the lidar-characteristic and the camera-characteristic.

    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 crosswalk navigation system for operating an automated vehicle in an intersection includes an intersection-detector, a pedestrian-detector, and a controller. The intersection-detector is suitable for use on a host-vehicle. The intersection-detector is used to determine when the host-vehicle is proximate to an intersection and determine when the intersection includes a cross-walk. The pedestrian-detector is suitable for use on the host-vehicle. The pedestrian-detector is used to determine a motion-vector of a pedestrian relative to the cross-walk. The controller is in communication with the intersection-detector and the pedestrian-detector. The controller is configured to determine a travel-path of the host-vehicle through the intersection, determine when the pedestrian will pass through an intersect-location where the travel-path intersects the cross-walk based on the motion-vector, and operate the host-vehicle to enter the intersection before the pedestrian passes through the intersect-location and to arrive at the intersect-location after the pedestrian passes through the intersect-location.

    Abstract: A scanning lidar suitable for use on an automated vehicle includes a laser, a beam-steering means, and a controller. The laser generates a pulsed laser beam. The beam-steering means steers the pulsed laser beam in a direction within a field-of-view of the lidar. The field-of-view is characterized as rectangular-shaped. The controller is in communication with the laser and the beam-steering means. The controller coordinates operation of the laser and the beam-steering means such that the lidar is characterized by an angular-resolution. The controller operates the beam-steering means in accordance with a first rectangular spiral pattern characterized by an aspect-ratio that corresponds to the field-of-view. The first rectangular spiral pattern causes a scan-segment to be skipped during a present-scan of the field-of-view due to the aspect-ratio. As such, the field-of-view is not scanned entirely at the angular-resolution.

    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: An automated vehicle radar system capable of self-calibration includes an antenna, a transceiver, and a controller. The antenna broadcasts a radar-signal and detects a reflected-signal reflected by an object. The transceiver determines a distance, an angle, and a range-rate of the object relative to the antenna based on the radar-signal and the reflected-signal. The controller determines a speed of a host-vehicle; determines when the object is stationary based on the speed, the angle, and the range-rate; stores in a memory a plurality of detections that correspond to multiple instances of the distance, the angle, and the range-rate as the host-vehicle travels by the object; selects an ideal-response of angle versus range-rate based on the speed; determines a calibration-matrix of the system based on a difference between the plurality of detections and the ideal-response; and adjusts an indicated-angle to a subsequent-object in accordance with the calibration-matrix.
