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 detect ion of the SMART KEY FOB (without interior trunk an d
hat shelf detection)
• LF-RF communication
• passive access trunk/tailgate via the trunk lid switch at the trunk
• max. 4 SMART KEY FOBs can be handled by the system
• communication to the engine management system via a single line interf ace
• communication to the ESCL via a single line interf ace

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 Wireless Communication

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 ve hicle’s interior and exteri or it is sufficient that at least one area is covered exactly by the correspond ing operating ranges of the antennas.
The functions of the SMAR T KEY system have to be provided in a clearl y 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.

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 fr om the SM ART KE Y FO B to th e v ehicle, t he st andar d radio fr equenc y (RF) is used (similar to the classic remote control functions) with FSK modulation.
