1. System configulation

1.1 Scope of SMART KEY SYSTEM

The System offers the following features:

• passive access for two doors, driver side and passenger side as well as trunk/tailgate

• passive start after interior detection of the SMART KE Y FOB (without inter ior trunk and

hat shelf detection)

• LF-RF communication

• passive access trunk/tailgate via the trunk lid switch at the trunk

• max. 3 SMART KEY FOBs can be handled by the system

• communication to the engine management system via a single line interface

• communication to the ESCL via a single line interface

1.2 Short description of the SYSTEM

1.2.1 General Definition of SMART KEY

The SMART KEY system is a system that allows the user to access and operate a
vehicle in a very convenient way. To access the vehicle no traditional key or remote
control unit is needed.

The user carries a SMART KEY FOB which itself does not require any conscious
actions by the user (e.g. operate a button).

After being triggered the vehicle sends out a request in a limited range. If the
SMART KEY FOB receives this request, it automatically sends a response to the
vehicle. Then the system decides whether to perform a particular action (unlocking,
locking…) or remain inactive.

1.2.2 Wi

Electromagnetic waves are used to exchange information between the vehicle and the
SMART KEY FOB. Bot h, vehicle and SMART KEY F OB are equipped with a transm itter,
a receiver and several antennas.

1.2.3 Concept Description

With this concept it is poss ible to have a set of interior antennas that covers the vehicle’s
interior and a set of exterior antennas that covers the vehicle’s exterior.
For an unambiguous sep aration between the vehicle’s interior and exterior it is sufficient
that at least one area is c overed exactly by the corresponding operating ranges of the
antennas.

reless Communication

The funct

ions of the SMART KEY system have to be provided in a clearly defined and
limited range. For th e up-link from the ve hicle to the SMART KEY FOB, a magnetic f ield
with a frequency of 125 k Hz and ASK modulation is used. In ductive antennas in and at
the vehicle radiate the electrom agnet ic energy.

echnical 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.
