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 KEY FOB (without interior trunk and hat shelf detection) • LF-RF communication (based on Siemens’ SMART KEY system) • passive access trunk/tailgate via the trunk lid switch at the trunk • max. 2 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 Weitergabe sowie Vervielfältigung dieser Unterlage, Verwertung und Mitteilung ihres Inhalts nicht gestattet, soweit nicht ausdrücklich zugestanden. Zuwiderhandlungen verpflichten zu Schadenersatz. Alle Rechte vorbehalten, insbesondere für den Fall der Patenterteilung oder GM-Eintragung 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. 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 covers the vehicle’s interior and a set of exterior antennas that covers 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. Inductive antennas in and at the vehicle radiate the electromagnetic 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 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. 1.3 System Overview / Block Diagram ECU sends LF challenge via exterior antenna Weitergabe sowie Vervielfältigung dieser Unterlage, Verwertung und Mitteilung ihres Inhalts nicht gestattet, soweit nicht ausdrücklich zugestanden.
