Abstract
A smart phone comprises an NFC antenna and a signal-send unit that communicates with the NFC antenna. The smart phone further comprises an NFC tag containing identification information. The smart phone is configured so that the signal-send unit transmits identification information to an ECU mounted within a vehicle, allowing remote control of the vehicle. The transmitted signals sent by the smart phone are encrypted by a third party.

A control system with a smart phone for a vehicle, the control system comprising an Engine Control Unit (ECU) positioned in the vehicle, and the smart phone comprising a Near Field Communication (NFC) antenna, an NFC tag, a signal-receive unit and a signal-send unit,
- the NFC tag contains identification information comprising at least one of an identification number or encryption information;
- the NFC tag is configured to communicate with the NFC antenna;
- the NFC antenna is configured to communicate with the signal-receive unit and the signal-send unit;
- and
- the control system is configured to execute a first series of steps:
- the ECU sends a challenge to the smart phone;
- the smart phone receives the signal via the signal-receive unit;
- the signal-receive unit relays the challenge to the NFC antenna;
- the NFC antenna relays the challenge to the NFC tag;
- the NFC tag sends a response corresponding to the challenge to the NFC antenna;
- the NFC antenna forwards the response to the signal-send unit;
- the signal-send unit forwards the response via the smart phone to the ECU, the ECU being configured to control the vehicle upon receiving the response to the challenge from the smart phone.
