Patent attributes
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.
