Description and operation

Description
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 does not require any conscious actions by the user (e.g. operate a RKE 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 Electrical Steering Column Lock (ESCL) is released. Again, a communication between the vehicle and the SMART KEY FOB is needed before any actions will be performed.
The System offers the following features :
Passive unlock via 4 doors
Passive locking via4 doors
Passive start
Passive access trunk via the trunk lid switch at the trunk
Max. 2 fobs can be handled by the system
Immobilizer backup antenna driver integrated into SSB for TP authentication (i.e. limp home mode)
Communication with engine management system
Communication with SRX
LF-RF communication
1.
Passive unlock
The system allows the user to access (unlock) the vehicle without performing any actions with the SMART KEY FOB.
2.
Passive locking
The system allows the user to lock the vehicle by pushing a button on door handle with the SMART KEY FOB.
3.
Button start
The system allows the user to switch the power modes (Off, Accessory, Ignition), as well as to start and stop the vehicle’s engine without performing any actions with the SMART KEY FOB. See Button Engine Start system specification.
4.
LIMP HOME Mode
Additionally, the system offers so called “limp home mode”, which is the user can operate all vehicle functions by pushing the key into the SSB.
Smart Key ECU (SMK ECU)
The SMK ECU manages all functions related to “Passive Unlock”, “Passive Lock” and “Passive Authorization for Engine Start Operation”.
It reads the inputs (Push button in door handle, Start Stop Button (SSB), PARK position Switch), controls the outputs (e.g. exterior and interior antennas), and communicates via the CAN as well as a single line interface to further devices of the car.
For communication with the SMART KEY FOB, SMK ECU generates a request (challenge) as an encoded and modulated 125kHz 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 SRX
Single Line Interface to EMS
Input stage
LF antenna amplifier/driver
CAN communication with BCM
The LF antenna amplifier/driver generates a 125kHz sinusoidal carrier signal which is distributed to the different antennas.
Smart Key FOB
The system supports up to 2 SMART KEY FOBs.
The main functions of the SMART KEY FOB are :
Passive functionality: receives LF-challenge and sends automatically RF response.
Classic RKE function by action up to 4 push buttons.
Transponder-functionality in case of a flat battery or a disturbed communication.
Antennas
1.
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 (or 134.2) 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 or tailgate.
Up to three antennas cover the vehicle’s interior and the trunk or tailgate interior: two in the passenger compartment and one in the tailgate room or trunk.
2.
Bidirectional Immobilizer Antenna (for Limp Home):
The Immobilizer Backup Antenna is used for sending and receiving data: it emits a magnetic field (125 - 135 kHz challenge) and receives changes in the field strength (response of Transponder).
3.
Receiver
The SMART KEY FOB’s response is received via the RF receiver.
Door Handle
The front door handles of the two doors (driver door / passenger door) are equipped with emitting LF-antennas to emit the 125kHz signals. The front door handles are also equipped with a push button.
Push Button
The push button in door handle serves as a trigger to indicate the user’s intent to unlock or lock the vehicle.
The push buttons are installed at front doors, integrated into the door handles.
Another button is installed at the trunk or tailgate lid.
Operation
Passive Functions
The system allows the user to access the vehicle without having to perform any actions (e.g. RKE button pressing) with the SMART KEY FOB. It is sufficient that a valid SMART KEY FOB is located within a defined and limited range with respect to the vehicle. So the system is capable of detecting and authenticating a SMART KEY FOB in the ranges as specified below.
Operating Range
The SMART KEY FOB receives and interprets a challenge sent from the vehicle via the exterior antennas in a free space range of min. 0.7m measured around the exterior antennas which are integrated in the door handles; refer to the below given picture. The trunk or tailgate access range is also min. 0.7m measured from the antenna position.
The SMART KEY FOB receives and interprets a challenge sent from the vehicle via the exterior antennas in a free space range of min. 0.7m measured around the exterior antennas which are integrated in the door handles; refer to the below given picture
Passive Access (Passive Entry)
Push the door handle button when all doors locked indicates the operator’s intent to access the vehicle and thus triggers the system for unlock
Passive Locking (Exit)
Pressing one of the push buttons in the door handles when one of the following condition is fulfilled:
At least one door is unlocked and two_steps timer is not running or
Two_steps timer is running and one of the push button except Front Left side is triggered
indicates the operator’s intent to lock the vehicle and thus triggers the system for a lock.
Passive Trunk Warning (Sedan only)
Whenever the trunk is closed, SMK ECU uses a suitable search strategy to avoid trunk buzzer warning by a fob outside the vehicle. Then SMK searches for a SMART KEY FOB in the interior of the trunk. If a valid SMART KEY FOB is found in the trunk, the SMK ECU activates SMK external buzzer (TBD) to inform the user that the trunk has been closed with a fob inside the trunk.
SMK will send the trunk open command to BCM for trunk reopening if trunk reopening bit is set(BK)For this functionality, a “valid” SMART KEY FOB means any SMART KEY FOB that belongs to the vehicle, even if it’s DEACTIVATED.
   
A blind spot in the trunk similar to any RF disturbance may lead to no trunk warning. Due to the penetration of the bumper antenna into the trunk area the lid may open without an Identification Device outside.
A blind spot in the trunk similar to any RF disturbance may lead to no trunk warning
Smart Trunk
When a user with a valid Smart Key in possession stands in the vicinity of the rear bumper (within LF antenna range) for over 3 seconds, the trunk is opened.
   
Function is set through the User Setting Mode (USM) in the Cluster.
1.
Rear bumper antenna detects valid Smart Key in the vicinity.
2.
When a valid Smart Key enters the rear bumper antenna range, alert buzzer and hazard lamp is activated 1 time to acknowledge detection.
   
Smart Key Unit can detect a Smart Key within 0.7-1 m of the rear bumper.
If the Smart Key stays inside the detection range, alert buzzer and hazard lamp is activated 1 time every second throughout the duration of the Smart Key remaining in the detection range.
3.
If the Smart Key remains in the rear bumper detection range (antenna range) for over 3 seconds, alert buzzer and hazard lamp is activated 2 times and the trunk is opened.

Failsafe Functions (Backup For Limp Home)
In case of a discharged battery of the SMART KEY FOB or disturbed transmission, the following functions are available:
Unlocking / locking of doors or trunk (or tailgate depending of the vehicle configuration): use of mechanical key
User Information Functions
ID OUT Warning
1.
Preconditions :
(ACC or IGN1) & (any door open or trunk open)
2.
Event:
The last opened door is closed
3.
SMK action :
SMK searches for a SMART KEY FOB in the interior.
If no valid SMART KEY FOB is found, the SMK activates external buzzer and also sends ID OUT warning via CAN (exterior buzzer warning and internal buzzer warning).
If a door is opened and closed again during terminals on and inside valid fob, SMK re-enables the authentication and stops the warning. If the terminal is in ACC, SMK shall turn on immobilizer lamp.
   
If there is a LF error (LF overheating or LF antenna failure), the system will have the same behavior as it is with no fob found.
Fob Battery Low Voltage Detection
To detect fob low battery condition, certain battery voltage measurement and low voltage detection strategy are implemented into fob. The measurement of the battery voltage will be done if fob button is pressed or if a LF measurement command is received.
Learning Description
In this chapter, the learning procedure for SMK and FOBs is described.
For the learning of the SMK and FOBs, it's necessary to have a connection to the diagnostic tool.
Learning Mode
Whatever the mode, the learning procedures are managed by the SMK.
Prior to start learning service, Fob-In signal must be active and the vehicle secret code (called as PIN code) should be known.
Teaching Mode
This mode is used by the dealers in order to replace SMK and/or the set of keys, or to register additional keys for an existing system. That means the system already has been learnt with certain PIN Code. The PIN Code is fixed for the life time of the vehicle, therefore the same PIN Code must be used in this mode. Otherwise learning will be failed
Teaching Mode Procedure Description (Step By Step)
Objective : Key teaching procedure at service station
Initial state :
SMK replacement: SMK is not learnt and SMART FOB are already learnt with same PIN code
Additional or new keys teaching: SMK are already learnt with same PIN code

Starting After Replacing (Virgin Start)
Starting is possible by following process after replacing new smart key unit, FOB key.
It is for starting at virgin condition
All related parts are virgin condition (Smart key, ECM)
Press brake pedal in P or N range
Push the start button once with virgin smart key.
