Technical specifications 5.1. NFC Sensor Functions

- NFC Function : Read/Write function of NFC Smartcards/Smartphones. 5.2. Misuse Protections After 20 lock/unlock activations in less than 10 seconds the sensor deactivates detection functions for 30s. After 20 NFC activations with wrong TAG in less than 10 seconds the sensor deactivates NFC function for 30s. 5.3. NFC Reader Principle The NFC principle is based on electromagnetic coupling between 2 devices at close distance (few cm). The PCD emits an electromagnetic field on a 13.56 Mhz carrier. It will power the PICC via Induction. The PCD can transmit data via Miller Coding and receive data back via Load modulation.

Operational mode description 7.1. Functionnal mode The DHS is designed to send information to the CAN bus on following user events:

- When a card or a smartphone is detected closed to the NFC pad 7.2. NFC test mode Test mode NFC is activated when setting CAN signal on CAN bus When the car driver put his smartphone close to the door handle (*), then the authenticated signal is sent to the BCM.

(*) and authenticated 7.3. Actuation test The actuator test is activated by CAN signal. The DHS shall perform the actuator test requirement as described below :

1. It shall turn on the antenna for a delay set to 10sec., and look for an external device with RF discovery polling rate as short as possible 2. If it finds an appropriate counterpart (NFC-A Type 4), it shall activate and send the SELECT command. 3. It shall feedback the result by changing the parameter "authenticated NFC-counterpart"

The DHS Application shall execute the actuator test (when requested) at any time regardless of the Misuse or K15 State and ESM (Energy Saving Mode) The field is turned on during the complete duration of the actuator test.

"Including regulatory notices for FCC and user manual requirements for EU. In the case of EU, this is not reviewed by the NB, but EU requirements must be included before marketing the product in EU. "

Refer to Testing Tool instruction chapter. 9. Homologation setup 9.1. General Test conditions General test conditions valid for all tests :

- All materials within 100mm around the door handle sensor during the test process (includes Handle fixations - Sensor fixture / Holder, sockets, base plate, -, actuation system robot, arms, -, tester mechanics, ) shall be made of non conductive material and as electrostatic neutral as possible

- Conductive environment (Robot, arms, jig walls, etc ) shall be at least 100mm away from

-

Door Handle Assembly throughout the test sequence (except for Targets themselves). The DHS shall have its dedicated power supply. This power supply shall be a low noise linear power supply (switch mode power supplies are prohibited)

- No noise shall be visible by oscilloscope on DHS supply line.

Test Box procedure Before to start any test, check for each LED and corresponding output that sensor is working fine:

-

approach TAG against NFC area => check NFC function 11.3.1. Test box function:

To set the sensor in normal mode, as it is in vehicle configuration without communication with BCM, let the switch in position RF-OFF. To set the sensor in RF Discovery mode, set the switch in position RF-ON. The sensor will send continuous WUPA as described in chapter actuator test. To check no loss of detection Tag provided by continental shall lay against the DHS in front of NFC Area as describe in chapter NFC detection area. To exit the sensor from RF Discovery mode, set the switch in position RF-OFF. The sensor will exit from this mode to normal mode in about 1s.
