Abstract:
A steering-control system for an automated vehicle includes an object-detector and a controller. The object-detector is suitable for use on a host-vehicle. The object-detector is used to detect an other-vehicle approaching the host-vehicle, and to detect a stationary-object that defines a roadway traveled by the host-vehicle. The controller is in communication with the object-detector and adapted to operate the host-vehicle. The controller is configured to steer the host-vehicle towards a centered-position of a travel-lane of the roadway when a projected-path of the other-vehicle approaches the host-vehicle to a minimum-distance between the other-vehicle and the host-vehicle greater than a distance-threshold. The controller is also configured to steer the host-vehicle towards a biased-position of the travel-lane to increase the minimum-distance when the projected-path approaches the host-vehicle to less than the distance-threshold if the host-vehicle remains in the centered-position.
Abstract:
A method for operating a radar system on a vehicle to reduce nuisance alerts caused by a stationary structure proximate to the vehicle. The method includes determining a stationary count indicative of the number of targets detected by the radar system that are within a travel path of the vehicle and are classified by the radar system as stationary, and indicating that the vehicle is proximate to a stationary structure if the stationary count is greater than a count threshold.
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 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.
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:
A radar object detection system includes a first sensor and a controller. The first sensor emits a first radar signal toward a first area about a vehicle, and outputs a first signal indicative of detected targets proximate to the vehicle. The controller receives the first signal from the first sensor, determines when a trailer is connected to the vehicle based on the first signal, defines a shadow-zone that corresponds to a first portion of the first area obstructed by the trailer from being viewed by the first sensor, and ignores detected targets within the shadow-zone that are indicated by the first signal.
Abstract:
A radar object detection system includes a radar sensor and a controller. The radar sensor is configured to emit a radar signal toward a defined area proximate to the vehicle, and output a reflection signal indicative of a detected target present in the defined area. The controller is configured to receive the reflection signal from the radar sensor, determine if the detected target corresponds to a trailer towed by the vehicle, and define an exclusion zone characterized as occupied by the trailer and thereby excluded from the defined area where objects can be detected.
