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.

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 Editor : CU Jun Version: 0.1 Document name Project code ECO / DF No. Aug. 26. 2011 File: User Manual for SMK2.7 Rev1.doc Identification No. : Document No. Page 4 / 12 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).

SMK 2.7 ECU reads the inputs (Door Lock/unlock, SSB SW, ESCL unlock status, PARK position Switch, Brake input SW etc.), controls the outputs (e.g. exterior or interior antennas, terminal control output, ESCL power, Immobilizer antenna), and communicates via the CAN/LIN (depends on the vehicle) as well as a single line interface to further devices of the car. For the communication with the SMART KEY FOB, SMK 2.7 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. Or for immobilizer communicaiton, SMK 2.7 ECU sends 125Khz LF signal to SSB's immobilizer antenna, and receives Response from Immobilizer antenna. The main functional blocks of the SMK 2.7 ECU are: Power supply Microcontroller with FLASH Memory Single Line Interface to ESCL Single Line Interface to EMS Input stage LF antenna amplifier/driver Immobilizer Antenna output ESCL power supply Terminal Control(ACC, IGN1/2, Start Rly) CAN communication with Other ECU Immobilizer communication The LF antenna amplifier/driver generates a 125 kHz sinusoidal carrier signal, which is distributed to the different antennas. The signal for Interior antenna and exterior antenna 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) in case of PASE LF Antenna. And also the signal for immobilizer antenna is ASK modulated signal. Amplitude Shift Keying for write and AM/PM for the read operation. The receiver charteristics(amplifier gain, filter cutoff frequencies) can be optimized to system and transponder requirements.
