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.
Claims20
A street sign authentication arrangement for a motor vehicle, the arrangement comprising:
- an RFID tag reader configured to read information encrypted on a street sign encountered by the motor vehicle;
- and
- an electronic processor communicatively coupled to the RFID tag reader, the electronic processor being configured to:
- verify, based on the information read from the street sign, that the information was encrypted by an authorized entity;
- and
- control 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;
- and
- refrain 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.
A street sign authentication method for a motor vehicle;
- the method comprising;
- reading information encrypted on a street sign encountered by the motor vehicle;
- determining, based on the information read from the street sign, whether the information was encrypted by an authorized entity;
- controlling movement of the motor vehicle based on the information read from the street sign if it was determined that the information was encrypted by the authorized entity;
- and
- refraining from controlling movement of the motor vehicle based on the information read from the street sign if it was determined that the information was not encrypted by the authorized entity.
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;
- determine, based on the information read from the street sign, whether the information was encrypted by an authorized entity;
- control movement of the motor vehicle based on the information read from the street sign if it is determined that the information was encrypted by the authorized entity;
- and
- refrain from controlling movement of the motor vehicle based on the information read from the street sign if it is determined that the information was not encrypted by the authorized entity.
