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.

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 (125 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 column 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 communication (500kbps)

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 (125 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.

Transponder Antenna:

Built in the Start Stop Button to communicate with the transponder by a base station and using wireless communication :(125 kHz)
