Automated vehicle operation to compensate for sensor field-of-view limitations
Abstract
An operating system for an automated vehicle equipped with limited field-of-view sensors is provided. The system includes an object-detector and a controller. The object-detector detects objects proximate to a host-vehicle. A field-of-view of the object-detector is characterized by a preferred-portion of the field-of-view, where the preferred-portion is characterized as preferred for using the object-detector. The controller is in communication with the object-detector. The controller steers the host-vehicle to align the preferred-portion with a detected-object. The system optionally includes an intersecting-road-indicator that indicates an intersecting-road connected to an intersection approached by the host-vehicle, and the controller is in communication with the intersecting-road-indicator. The controller designates an intersecting-road as the detected-object, and steers the host-vehicle to align the preferred-portion of the object-detector with the intersecting-road when the host-vehicle approaches the intersection.
