1. System configulation

1.1 Scope of HI IBU System

IBU(Integrated Body control unit) integrate BCM, Smart Key system and TPMS receiver in one ECU

1.1.1 Smart key system offer following feature

 passive access to two doors and trunk; driver side, passenger side, and trunk/tailgate  passive start after interior detection of the SMART KEY FOB.  LF-RF communication (based on Continental’s SMART KEY system)  passive access/locking of the two front doors via a toggle push button in the door

handles

 passive access trunk/tailgate via the trunk lid switch at the trunk  immobilizer backup solution integrated into IBU  communication to the engine management system via a single line interface  communication to the ESCL via a single line interface  block of the steering column by the ESCL device

1.1.2 BCM functions offer following feature

 BCM functions are for user convenience and warning for user safety  BCM functions directly or indirectrly control Lamps, Indicators, Rear curtain, Steering

wheel heat and relay

 BCM function s receive inputs by wire or communication (CAN, LIN)

1.1.3 TPMS receiver functions offer following feature

 Process receive data from TPMS sensor  Do display or warning according to received TPMS sensor data

1.2 short description of the SYSTEM

1.2.1 General Definition of IBU

The SMART KEY system is a system that allows the user to access and operate a vehicle in a very convenient way.

The SMART KEY system is triggered by pressing a push button in the door handle or by pressing a start-stop button in the dash board.

After triggered, the vehicle sends out a LF telegram to all antenna output. And then Smartkey FOB measures the power of each antenna, and sends this information to SMARTKEY UNIT(IBU). From this information, Smart Key unit determines the location of SMART KEY FOB and decides whether to perform a particular action (unlocking, locking…) or to remain inactive.
