possible, but just as the unlock sensor there is only a LIN or UART signalization for the lock
touch.
Keyless access is enabled by activating the sensors on the door handle in combination with
the door handle-ECU, whereby the vehicle can be unlocked or locked.
1.1.2 Function NFC:
To enable communication with an NFC device, the door handle electronics CA + NFC has a
highly integrated transceiver IC for contactless communication at 13,56MHz for automotive
applications. This reader has a gateway function, the possibility to buffer required data and
various diagnostic information can be provided as well.
The data is transferred to the NFC device according to ISO/IEC 14443-A and the data
transmission to the vehicle is realized via LIN-Bus interface. ECP is implemented to
communicate with Apple NFC devices.
In LPCD mode the door handle electronics checks the magnetic field for amplitude or phase
change. This LPCD polling takes place in adjustable interval lengths.
1.2 Environmental conditions
- Operating temperature range: -40 to +85°C
- Storage temperature range: 40 to +105°C
- Repainting temperature: 110°C for 1h, 130°C for 0,25h
- Room temperature: +23°C ± 5°C
- Air humidity: 25% to 90%
- Test temperature for EOL-Test: Room temperature
1.3 General manufacturing instructions
- At the beginning of the production process, the serial number is marked on the
PCB.
- An unacceptable deflection of the board while placing components must be
avoided.
- PCB separation is a particularly critical process. Torsional stress during separation
and impact stress during punching shall be avoided.
- The method for depanelling must ensure that no components be damaged. An
evidence of the equipment manufacturer is necessary.
- The soldering process should be reflow soldering and selective wave soldering.
- Active cooling of the board after soldering is not permitted.
- The components specifications concerning the temperature gradients must be
adhered.
- A reworking of a SMD component with a soldering iron is prohibited.
