Functional description
The radio frequency transceiver is part of a remote keyless entry system of a
vehicle central door locking system.
This vehicle central door locking system consist out of
•
Remote control key with UHF transmitter (NOT part of the MQB BCM)
•
Radio frequency transceiver with PCB-Antenna (part of the MQB
BCM)
•
Door ECU, which can drive the car door locks to lock or unlock the car
(NOT part of the MQB BCM)
•
Door locks for the central door locking functionality (NOT part of the
MQB BCM)
The transceiver has a self-polling mode and is permanently scanning for valid
key data, with matching characteristics.
(Note: This data are typically received, when a valid remote control key is in
range and one of its push-buttons is pressed.)
When the data are matching the characteristics, the transceiver will hand over
this data to the micro controller of the MQB BCM.
With the help of this micro controller, it is validated, whether this data have
been transmitted from the authorized remote control key. When the validation
was successful, the MQB BCM will send this information via a CAN-network to
the door ECU.
This door ECU will drive the connected door lock according to the wish of the
operator, who pressed the push button of the remote control key. Hence the
doors will be locked or unlocked.
