HUF13145 Door Handle with NFC User Manual

HUF13145 Door Handle with NFC

General description of the door-handle

The Door-Handle HUF13145 with NFC is equipped with sensors that enable users of a car with passive entry system to lock/unlock the doors by carrying the key fob or an authorised NFC-Device with them.

NFC-Reader:
When an NFC-Device approaches to the NFC-Antenna, the door handle sends a signal to the electronic control unit to initiate the authorisation sequence for unlocking or locking the door.

Communication Interfaces

Following picture shows a simplified diagram of the system.

The door-handle communicates with the Electronic Control Unit (ECU) by using one-wire interface and with the NFC-Device by using Near Field Communication.

• Communication with the NFC-Device
  • Near Field Communication between the door-handle and the NFC-Device.
• Communication with the ECU
  • Bidirectional communication with the ECU during the NFC-authorisation sequence
