3.Outline of the system
Existing BCM, SMK, TPMS receiver integrated ECU as well as smart key function. Body
and TPMS related control unit (integrated PDM, RF Receiver). It controls the power
operation mode (ACC, IGN1, IGN2, START) of the vehicle according to the operation of
the START / STOP button when the card key / FOB is successfully authenticated.
Various Lamp, Indicator, Rear Curtain, Side mirror, Relay control related to BCM function
Directly and indirectly, and performs a warning and display function for processing data
received from the TPS sensor.
3.1. IBU WSMK
Smart Key System
The smart key unit controls the smart key system. When the user inputs the door handle
or the start button, the smart key unit transmits the LF signal (134.2 KHz) to the smart
key FOB and receives the signal (433 MHz) from the FOB to perform a related function .
● Terminal control function: Control terminal (IGN1, IGN2, ACC) power when inputting
start / stop button
● Immobilizer function: Function for emergency start or RKE key authentication when
discharging FOB battery
● Start stop button LED lighting control
● Electrical steering colume lock (ESCL) control function - excluding domestic / North
American / Canadian specifications
BCM function System
BCM function is a function for user convenience / warning, and it can directly or indirectly
control various indicators, sensor power, hot wire and relay control through
communication or switch input. It also performs Immobilizer function.
● Terminal control function: IGN1, IGN2, ACC power control
● Immobilizer function: Perform function for RKE Key authentication
● Head lamp washer relay control function - Optional function
● Indicator control function
● Auto light control function
● Puddle & Pocket Lamp control function
● Solenoid control function (ATM)
● PAS power control function
● LIN communication
● Chassis CAN communication (500kbps)
● Body CAN communicaton (500kbps)
3.2. LF Antennas:
Inductive antennas in and at the vehicle are used to transform the current, driven by the
SMK antenna driver, into a magnetic field (134.2 kHz), which is the carrier for the SMK
challenge.
Two antenna covers the vehicle’s interior. One antenna covers the interior of the Trunk.
Two antennas in the Door Handles (Left side and Right side) cover the area around the
doors. One antenna in the rear bumper covers the area around the trunk for access to
the trunk. Those antennas are based on ferrite core and have a pair of twisted copper
cables from antenna to pin header.
3.3. Transponder Antenna:
Built in the Start Stop Button to communicate with the transponder by a base
station and using wireless communication :(134.2kHz)
3.4 Installation in vehicle
The Smart Key ECU is installed inside the vehicle.
