Description |
• | Passive unlock via 4 doors |
• | Passive locking via4 doors |
• | Passive start |
• | Passive access tailgate via the tailgate lid switch at the tailgate |
• | 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. |
• | 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 |
• | Passive functionality: receives LF-challenge and sends automatically RF response. |
• | Classic RKE function by action up to 3 push buttons. |
• | Transponder-functionality in case of a flat battery or a disturbed communication. |
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 trunk 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. |
Operation |
Operating Range |
• | 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 |
|
1. | Preconditions : All
terminals OFF & at least one door open & locking status is not
locked checked by SMK periodically every 100ms, as long as CAN/LIN
active. |
2. | Event: At least 1 door knob status changed from unlock to lock. |
3. | SMK actions :
If no fob or no TP has been found, no action is required. If
any valid fob or valid TP has been found, SMK unlocks the vehicle by
sending a CAN Key Reminder unlock message with the fob number. If any valid fob has been found, SMK unlocks the vehicle by sending a CAN/LIN Key Reminder unlock message with the fob number. |
1. | Preconditions : All
terminals OFF & any door (including tailgate) open & no FOB-IN
& no locking status (checked by SMK periodically every 100ms, as
long as CAN/LIN active) |
2. | Vehicle action : Closing last door or tailgate with knobs locked state, or with a locking in progress |
3. | SMK actions : Before elapsing 500ms after the closing if all doors are locked then :
If no fob has been found, no action is required. If any valid fob or valid TP has been found, SMK sends unlock command via CAN and activates ext. buzzer warning. If any valid fob has been found, SMK sends unlock command via CAN/LIN and activates ext. buzzer warning. |
1. | If
terminal state is ACC or IGN and all doors are closed and that user
triggers a SMK lock, a search is started at the exterior of the vehicle
from the side of the trigger. |
2. | If no valid Fob is found no action is required, but if a valid Fob is found then a Buzzer warning shall be started. |
3. | If
"tailgate Option == On" and "tailgate LockUnlockOption == On" are
fullfilled, Lock warning is including tailgate as a door and tailgate
lockunlock knob as a door unlock switch. |
1. | If
terminal state is OFF and not all doors are closed and that user
triggers a SMK lock, a search is started at the exterior of the vehicle
from the side of the trigger. |
2. | If no valid Fob is found no action is required, but if a valid Fob is found then a Buzzer warning shall be started. |
3. | If
"tailgate Option == On" and "tailgate LockUnlockOption == On" are
fullfilled, Lock warning is including tailgate as a door and tailgate
lockunlock knob as a door unlock switch. |
1. | If
terminal state is OFF and ATWS is considered as Disarmed and all doors
are closed and that user triggers a SMK lock, a search is started at
the Interior of the vehicle; |
2. | if
no valid Fob is found the search for SMK locking will be started, but
if a valid Fob is found then a Buzzer warning shall be started. |
3. | If
"tailgate Option == On" and "tailgate LockUnlockOption == On" are
fullfilled, Lock warning is including tailgate as a door and tailgate
lockunlock knob as a door unlock switch. |
1. | If
terminal state is ACC or IGN and vehicle speed is less than 3km/h, a
periodic search (every 3s) is done at the interior of the vehicle to
check that the valid fob is still in the in the vehicle. |
2. | If no valid Fob is found a Warning is started, but if a valid Fob is found then no action is started. |
• | Unlocking / locking of doors or trunk (or tailgate depending of the vehicle configuration): use of mechanical key |
ID OUT Warning |
1. | Preconditions :
|
2. | Event: The last opened door is closed |
3. | SMK action : SMK searches for a SMART KEY FOB in the interior.
|
|
– | 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 |
• | 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. |
