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.

1.2.2 Wireless Communication

Electromagnetic waves are used to exchange information between the vehicle and the

SMART KEY FOB. Both, vehicle and SMART KEY FOB are equipped with a transmitter,

a receiver and several antennas.

1.2.3 concept Description

With this concept it is possible to have a set of interior antennas that cover the vehicle’s

interior and a set of exterior antennas that cover the vehicle’s exterior.

For an unambiguous separation between the vehicle’s interior and exterior it is sufficient

that at least one area is covered exactly by the corresponding operating ranges of the

antennas.

The functions of the SMART KEY system have to be provided in a clearly defined and

limited range. For the up-link from the vehicle to the SMART KEY FOB, a magnetic field

with a frequency of 125 kHz and ASK modulation is used.

Technical aspects of 125 kHz – magnetic field:

 virtually no reflections,

 cubical decrease of field strength  allows good range control,

 released frequency band (ISM),

 high penetration,

 low quiescent current demand due to 125 kHz input stage (SMART KEY FOB),

 less sensitive for detuning compared to higher frequency.

For the down-link from the SMART KEY FOB to the vehicle, the standard radio frequency

(RF) is used (similar to the classic remote control functions) with FSK modulation.

1.2.4 System Architecture

The system is designed as an optional system, making it possible to equip vehicles of the

same car-Line with different levels of access control systems.

The system is suitable to be integrated into an existing architecture that provides central

locking functions with standard remote control. This proposal assumes that the following

functions / devices are already present in the vehicle’s architecture.

 Central locking system (latch / motor – drivers etc.)

 Standard body control functions

 Warning buzzer

 Indicators

 Lamps

 Wiper control system

 TPMS warnging and display

 Convenience equipments

1.2.5 Main Functions

 The system allows the user to access and exit (unlock and lock) the vehicle without

performing any actions with the SMART KEY FOB.

 The system allows the user to control ESCL lock/unlock, to operate relaies to provide

power(Off, Accessory, Ignition) to other ECU, and to start/stop the vehicle’s engine

without performing any actions with the SMART KEY FOB.

 Additionally, the system offers the user can operate all vehicle functions by contacting

the Fob to the Start/stop button, which have Immobilizer antenna(terminal control

fuction), and by inserting the mechanical key blade into the door handle(Passive

access function).

2.3 HI IBU ECU

IBU ECU manages all functions related to “Passive Access”, “Passive Unlocking” ,

“Passive Authorization for Operation”, "Terminal control" .

IBU ECU reads the inputs (Door Lock/unlock, SSB SW, ESCL unlock status, PARK

position Switch, Brake input SW etc.), controls the outputs (e.g. exterior or interior

antennas, terminal control output, ESCL power, Immobilizer antenna), and

communicates via the CAN (depends on the vehicle) as well as a single line interface

to further devices of the car.

For the communication with the SMART KEY FOB, IBU ECU generates a request

(challenge) as an encoded and modulated 125 kHz signal at the inductive antenna

outputs and receives the SMART KEY FOB’s response via the RF receiver.

Or for immobilizer communicaiton, IBU ECU sends 125Khz LF signal to SSB's

immobilizer antenna, and receives Response from Immobilizer antenna.

The main functional blocks of the IBU ECU are:

 Power supply

 Microcontroller with FLASH Memory

 Single Line Interface to ESCL

 Single Line Interface to EMS

 Input stage

 LF antenna amplifier/driver

 Immobilizer Antenna output

 ESCL power supply

 Terminal Control(ACC, IGN1/2, Start Rly)

 CAN communication with Other

 ECU Internal receiver(433Mhz)

 Rear curtain control

 Steering wheel heat control

 Head lamp wahser relay control

 Indicators control

 TPMS data receiver

 Lamps control

 High speed CAN communication

 Low speed CAN communicaton

 LIN communication

The LF antenna amplifier/driver generates a 125 kHz sinusoidal carrier signal, which is

distributed to the different antennas.

The signal for Interior antenna and exterior antenna is 100%-ASK modulated by

switching on and off the carrier (the data is Manchester encoded). The power of the

carrier is adjustable by software, which means, it is possible to set the power level of

the antenna driver for every LF-telegram (e.g. power level stored in the EEPROM) in

case of PASE LF Antenna.

And also the signal for immobilizer antenna is ASK modulated signal. Amplitude Shift

Keying for write and AM/PM for the read operation. The receiver charteristics(amplifier

gain, filter cutoff frequencies) can be optimized to system and transponder

requirements.
