Alle Rechte vorbehalten, insbe-sondere für den Fall der Patenterteilung oder GM-Eintragung 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 KEY FOB (without interior trunk and hat shelf detection) • LF-RF communication (based on Siemens’ 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 • max. 2 SMART KEY FOBs can be handled by the system • immobilizer backup antenna driver integrated into MSL • communication to the engine management system via a single line interface • communication to the MSL via a single line interface • block of the steering column by the MSL 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 user carries a SMART KEY FOB which itself does not require any conscious actions by the user (e.g. operate a button). The SMART KEY system is triggered by pressing a push button in the door handle. 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. In a similar manner the vehicle’s Mechatronic Steering Lock (MSL) is released. Again, a communication between the vehicle and the SMART KEY FOB is needed before any actions will be performed. 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.

Zuwiderhandlungen ver-pflichten zu Schadenersatz. Alle Rechte vorbehalten, insbe-sondere für den Fall der Patenterteilung oder GM-Eintragung 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. 1.2.4 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

It reads the inputs (Push button, MSL Knob Push Switch, PARK position Switch), controls the outputs (e.g. exterior and interior antennas), and communicates via the CAN/LIN (depends on the vehicle) as well as a single line interface to further devices of the car. For communication with the SMART KEY FOB, the SMK ECU generates a request (challenge) as an encoded and modulated 125 kHz signal at the inductive antenna outputs and receives the SMART KEY FOB’s response via the external RF receiver. The main functional blocks of the SMK ECU are: • Power supply • Microcontroller with FLASH Memory • Single Line Interface to MSL • Single Line Interface to SRX • Single Line Interface to EMS • Input stage • LF antenna amplifier/driver • LIN communication with BCM/ETACS (except EN, VQ ; CAN communication)

Zuwiderhandlungen ver-pflichten zu Schadenersatz. Alle Rechte vorbehalten, insbe-sondere für den Fall der Patenterteilung oder GM-Eintragung The LF antenna amplifier/driver generates a 125 kHz sinusoidal carrier signal which is distributed to the different antennas. The signal is 100%-ASK modulated by switching on and off the carrier (the data is Manchester encoded). The power of the carrier is adjustable by software, which means, it is possible to set the power level of the antenna driver for every LF-telegram (e.g. power level stored in the EEPROM). The LF antenna driver consists of a number of outputs with different switching features. 1. switch on/off driver door handle antenna 2. switch on/off passenger door handle antenna 3. switch on/off bumper antenna for access to the trunk 4. switch on/off interior antennae 5. switch on/off trunk antenna (except SUV) The SMK ECU comprises: • the electronics described above • a plastic housing Emitting LF Antennas: Inductive antennas in and at the vehicle are used to transform the current, driven by the SMK ECU antenna driver, into a 125 kHz magnetic field, which is the carrier for the SMART KEY challenge. Three antennas cover the vehicle’s exterior: two antennas in the Door Handles (DS and PS) cover the area around the doors; one antenna in the rear bumper covers the area around the trunk/tailgate. Up to three antennas cover the vehicle’s interior and the trunk interior: two in the passenger compartment and one in the trunk. (In case of SUV, Three antennas cover the vehicle’s interior and no trunk antenna) Those antennas are based on either Vitrovac™ or ferrite core and have twisted pair terminals on standard pin header.
