1. System configulation
1.1 Scope of SMART KEY SYSTEM
The System offers the following features:
passive access to two doors and trunk; driver side, passenger side, and trunk/tailgate
passive start after interior detection of the SMART KEY FOB
(without interior trunk detection)
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 SMK 2.7
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
1.2 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 SMART KEY system is triggered by pressing a push button in the door handle.
After triggered, the vehicle sends out a request in a limited range. If the SMART KEY
FOB receives this request, SMART KEY FOB automatically sends a response to the
vehicle. Then the system decides whether to perform a particular action (unlocking,
locking…) or to remain inactive.
In a similar manner, the SMART KEY system is triggered by pressing a start-stop
button in the dash board.
After triggered, the vehicle sends out a request in a limited range(especially interior
region). If the SMART KEY FOB receives this request, SMART KEY FOB
automatically sends a response to the vehicle. Then the system decides whether to
perform a particular action (terminal status change…) 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

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).
