1. |
Passive unlock
The system allows the user to access (unlock) the vehicle without performing
any actions with the SMART KEY FOB. This feature could be different
depending on platform as follows:
|
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 release ESCL and 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.

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. |
External Receiver
The SMART KEY FOB’s response is received via the external RF receiver,
which is connected to the SMK ECU via a serial communication Line.
The SMK ECU provides a connector pin for the serial communication Line.
|
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 trunk/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 trunk/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 "b_TailgateOption == On" and "b_TailgateLockUnlockOption == 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 "b_TailgateOption == On" and "b_TailgateLockUnlockOption == 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 "b_TailgateOption == On" and "b_TailgateLockUnlockOption == 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.
|
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.
