Abstract
A street sign authentication arrangement for a motor vehicle includes an RFID tag reader for reading information encrypted on a street sign encountered by the motor vehicle. An electronic processor is communicatively coupled to the RFID tag reader, and verifies, based on the information read from the street sign, that the information was encrypted by an authorized entity. The processor controls movement of the motor vehicle based on the information read from the street sign if the processor is able to verify that the information was encrypted by the authorized entity. The processor refrains from controlling movement of the motor vehicle based on the information read from the street sign if the processor is not able to verify that the information was encrypted by the authorized entity.
Claims18
A street sign authentication arrangement for a motor vehicle, the arrangement comprising:
- an image-capturing device configured to capture an image of a street sign encountered by the motor vehicle;
- an RFID tag reader configured to read information encrypted on the street sign;
- and
- an electronic processor communicatively coupled to the RFID tag reader and to the image-capturing device, the electronic processor being configured to:
- recognize the street sign in the captured image;
- cause the RFID tag reader to read the information encrypted on the street sign in response to recognizing the street sign in the captured image;
- and
- control movement of the motor vehicle based on the information read from the street sign.
A motor vehicle, comprising:
- an image-capturing device configured to capture an image of a street sign encountered by the motor vehicle;
- an electronic tag reader;
- and
- an electronic processor communicatively coupled to the image-capturing device and the electronic tag reader, the electronic processor being configured to:
- cause the electronic tag reader to read information encrypted on a tag on the street sign in response to the image-capturing device capturing the image of the street sign;
- and
- control movement of the motor vehicle based on the information read from the street sign.
A street sign authentication method for a motor vehicle, the method comprising the computer-implemented steps of:
- capturing an image of a street sign encountered by the motor vehicle;
- recognizing the street sign in the captured image;
- reading information encrypted on the street sign, wherein the information encrypted on the street sign is read in response to the recognizing of the street sign in the captured image;
- and
- automatically controlling movement of the motor vehicle based on the information read from the street sign.
