## 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.

## Claims

### Claim 1

An infrastructure-device status-verification system suitable for use by an automated vehicle, said system comprising:
a transceiver suitable to install on a host-vehicle, said transceiver used to receive an indicated-status of an infrastructure-device proximate to the host-vehicle;
an object-detector suitable to install on the host-vehicle, said object-detector used to determine a detected-status of the infrastructure-device; and
a controller in communication with the transceiver and the object-detector, wherein the controller determines a confirmed-status of the infrastructure-device based on the indicated-status and the detected-status.

### Claim 2 (depends on 1)

The system in accordance with claim 1, wherein the object-detector is a camera, the infrastructure-device is a traffic-signal operable to selectively emit a light characterized by a color, and the detected-status and the indicated-status are indicative of the color emitted by the traffic signal.

### Claim 3 (depends on 1)

The system in accordance with claim 1, wherein the object-detector is one of a radar-unit and a lidar-unit, the infrastructure-device is a gate operable to a state including an open-state that allows traffic to pass by the gate and a closed-state that prevents traffic from passing by the gate, and the detected-status and the indicated-status are indicative of the state of the gate.

### Claim 4 (depends on 1)

The system in accordance with claim 1, wherein the controller maintains the confirmed-status based only on the indicated-status for a, occlusion-time when a field-of-view between the object-detector and the infrastructure-device becomes occluded.

### Claim 5 (depends on 1)

The system in accordance with claim 1, wherein the controller maintains the confirmed-status based only on the detected-status for an interruption-time when reception of the indicated-status by the transceiver is interrupted.
