System configulation1.1 Scope of SMART KEY SYSTEMThe 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 doorhandles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 device1.2 short description of the SYSTEM1.2.1 General Definition of SMART KEYThe SMART KEY system is a system that allows the user to access and operate avehicle in a very convenient way. To access the vehicle, no traditional key or remotecontrol 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 KEYFOB receives this request, SMART KEY FOB automatically sends a response to thevehicle. 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-stopbutton in the dash board.After triggered, the vehicle sends out a request in a limited range(especially interiorregion). If the SMART KEY FOB receives this request, SMART KEY FOBautomatically sends a response to the vehicle. Then the system decides whether toperform a particular action (terminal status change…) or to remain inactive.1.2.2 Wireless CommunicationElectromagnetic waves are used to exchange information between the vehicle and theSMART KEY FOB. Both, vehicle and SMART KEY FOB are equipped with a transmitter,a receiver and several antennas.

For the up-link from the vehicle to the SMART KEY FOB, a magnetic fieldwith 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 ArchitectureThe system is designed as an optional system, making it possible to equip vehicles of thesame car-Line with different levels of access control systems.The system is suitable to be integrated into an existing architecture that provides centrallocking functions with standard remote control. This proposal assumes that the followingfunctions / devices are already present in the vehicle’s architecture.Central locking system (latch / motor – drivers etc.)Standard body control functionsWarning buzzer

The power of thecarrier is adjustable by software, which means, it is possible to set the power level ofthe antenna driver for every LF-telegram (e.g. power level stored in the EEPROM) incase of PASE LF Antenna.And also the signal for immobilizer antenna is ASK modulated signal. Amplitude ShiftKeying for write and AM/PM for the read operation. The receiver charteristics(amplifiergain, filter cutoff frequencies) can be optimized to system and transponderrequirements.
