Abstract
An infrastructure-device status-verification system suitable for use by an automated vehicle includes a transceiver, an object-detector, and a controller. The transceiver is suitable to install on a host-vehicle. The transceiver is used to receive an indicated-status of an infrastructure-device. The object-detector is suitable to install on the host-vehicle. The object-detector is used to determine a detected-status of the infrastructure-device. The controller is in communication with the transceiver and the object-detector. The controller determines a confirmed-status of the infrastructure-device based on the indicated-status and the detected-status. The system provides for increased confidence and security regarding information about the status of an infrastructure-device such as the traffic-signal (e.g. red, yellow, and green), thereby avoid miss-information caused by, for example, hacking or spoofing of V2I communications from the infrastructure-device, and overcome instances when the field-of-view between the object-detector and the infrastructure-device 26 becomes occluded after the confirmed-status has been established or determined.
