GENERAL

• In this document the Smart Keyless System [SKSJ is introduced.
• Smart Keyless System is the consequent development of well-known Remote Keyless Entry [RKEJ. The usage of the key fob by pressing the buttons is still possible, but not necessary any more to enter, lock, unlock the vehicle or to start it.
• The SKS system consists of Smart Key Device [SK□), RF and LF antennas and Smart Keyless Module [SKM ECUJ. Vehicle equipped with the SKS system provides very convenient and luxury features.
• The Model Nome of the described ECU is:
  • Smart Key Device [SKO)- Key Fob: SKO V1.3
  • Smart Key Module [SKM) – ECU: SKM V1.3

SKM Smart Key Module ECU
The SKM unit represents the main unit of the vehicle access system and is installed in the vehicle. Its function is communicotion, identificotion and awakening of SK□ modules by RKE, PEPS and Immobilizer protocols. Through CAN and LIN buses, it provides secure communicotion with in-vehicle systems. The integrated Power Management system ensures that the SKM is always in power efficient mode and only raises the sub-systems that ore essentially needed for the current system functionality.

SKM Smart Key Device Unit

• The SKD [Smart Key Device) module is a remote unit of SKS system which enables vehicle locking/unlocking functionality and provides o safe ignition of the vehicle even if the battery is not present in the module. It supports the conventional RKE functionality where the driver unlocks/locks the doors with pressing o button on the module. SK□ supports up to 5 mechanicol buttons for user vehicle interaction.
• In PEPS mode enables hands-free interaction with the vehicle which allows the driver to lock/unlock the vehicle doors and to start/stop the vehicle engine without performing any manual action either with the key fob or a mechanic□! key.

KEYLESS OPERATION AND FEATURES

• In the SKS (Smart Key System) the SKM ECU is connected with four LF Antennas positioned on the vehicle. Each antenna covers surrounding ore□ providing selective recognition of the key fob locotion in the vehicle vicinity. Other situations ore detected □s well, like the user approaching or leaving vehicle, entering vehicle, etc.
• The key fob (Smart Key Device) is to be found inside or outside the vehicle including the detection of the zone outside the vehicle (front, rear, left or right side).

PASSIVE ENTRY (UNLOCK)

• When the driver approaches the vehicle, the fob is identified using secure wireless communic□tion between the Smart Key Module (SKM) and the fob. A driver/passenger event (such □s contact with the door handles) triggers this outhenticotion. Once the fob hos been outhenticoted, the doors ore outomatically unlocked. This function is coiled passive entry (PE). Some operation principle is used for passive exit.
• Person with the SKD approaches to the locked vehicle. The side antenna is transmitting LF signal. If the magnetic field strength is high enough ( certain border is reached) the SKD stays □woke for additional LF communication by the other antennas driven sequentially. The additional LF communication guarantees the functionality, that only the valid key outside the vehicle outhenticotes the system to unlock the vehicle passively.
• The passive entry function allows the driver to unlock the vehicle’s doors without any user action on the key fob. Instead, user action is needed to trigger the system, such as approaching the door handle, touching the door handle, or pulling on it. When the cm hos detected this action, it starts the:
  • Outside fob locolizotion (search for fob outside the vehicle cobin, preferably by LFJ
  • Fob outhentication
• Finally, if □t least one paired key fob is locolized outside the vehicle cobin and outhenticoted, the vehicle outom□tic□lly unlocks its doors.
• If the magnetic field strength is not high enough (when SK□ is too for □way from the vehicle), the SK□ shuts down and waits for the next LF dot□. The vehicle remains locked.

PASSIVE LOCK

• The passive lock function allows the driver to lock the vehicle doors without any user action on the key fob.
• Before PEPS systems hod been introduced, the RKE function was used to lock vehicle doors. A button on the fob was dedicoted to door locking. With PEPS systems, lock button or o sensor is generally added on door handles to ovoid fob monipulotion. Users only hove to push this button or touch the handle to lock doors.
• Once this action is detected, the vehicle initiates:
  • Outside fob localization [search for fob outside the vehicle cabin)
  • Inside fob localization [search for fob inside vehicle cabin)
  • Fob authentication
• Finally, if at least one key fob is localized/authenticated outside the cabin and if no paired key fob is localized/outhenticoted inside the cabin, the vehicle locks its doors.
• Person with SKD is leaving the vehicle. The LF antenna is transmitting LF signal, which is recognized ond evaluated [RSSI measurement) by the SKD. If the magnetic field strength is high enough the SKD stays active for additional LF communicotion by the other LF antennas driven sequentially. The additional LF communicotion guarantees the functionality, that only the valid key outside the vehicle authenticates the system to lock the vehicle passively. If the SKD is left inside the vehicle, it won’t lock.

PASSIVE START

• When the driver presses the vehicle’s start/stop button, a new authentication process is executed. If the key fob is identified ond localized inside the car, the ignition procedure is started. This function is called passive start [PS).
• The passive start function allows the driver to start/stop the vehicle engine without the user interacting with the key fob. A start/stop engine button is added in the vehicle cabin (replacing the lock cylinder) which activates the passive start function. Once this action is detected, the vehicle initiates:
  • Inside fob localization (search for fob inside vehicle cabin, preferably by LFJ
  • Fob authentication
• Communication between o vehicle ond o fob is almost the some os for passive entry. The main difference between these two functions is that passive entry searches for fobs locoted outside the vehicle cabin, whereas passive start searches for fobs located inside the vehicle cabin. Finally, if ot least one paired key fob is localized inside the vehicle cabin ond authenticated, the vehicle enable/disable the driving system.

IMMOBILIZER
Immobilizer is o feature of the SKS system to provide the SKD authentication in case the SKD is not recognized or SKD battery is low. In this case SKD should be place on on interior LF ontenno.

SHORT RANGE LF COMMUNICATION
Short-range bidirectional LF communication is used for two different purposes. First, it serves os on immobilizer and second, it is used for system configuration for learning. During the learning process, the relevant doto for authentication [secret keys, length of challenge and response) or communication [modulation scheme, dot□ rote) ore transferred from the SKM to the key and stored in the SK□ key fob. In both coses, the SK□ operates with or without battery. The SKM control unit applies the magnetic field that supplies the circuit with power and is used for bidirectional communication.

AUTHENTICATION RANGE

• Localization is o key feature of any PE/PS system. Localization means the key is detected when near the vehicle and, depending on the strategy desired, con distinguish if the key is inside or outside the vehicle.
• Locolizotion is performed by measuring the LF signal level [RSSI) during communication with the vehicle. The RSSI is acquired by the fob and sent bock to the vehicle. The vehicle then analyses the dot□ to determine the fob’s position. Bemuse the spatial orientation of the key fob is not known, the RSSI measurement must be performed for the x, y, and z oxes using 30 coil inside the key fob.
• The vehicle hos four to six LF antennas. These antennas produce on LF magnetic field which covers the vehicle cabin os well os the perimeter near the vehicle. The primary goal is to localize o fob inside or outside the vehicle cabin.

INSIDE THE VEHICLE COVERAGE
The antennas inside the vehicle ore arranged so that the most common fob locations [such os seats) ore covered. Three antennas ore placed to cover both sides of the vehicle. In addition, each antenna’s LF power is adjustable so that o constant field strength matches the cabin perimeter.

OUTSIDE THE VEHICLE COVERAGE
For the passive entry function, LF antennas ore positioned to cover vehicle access paths. These paths ore:

• The left side of the vehicle
• The right side of the vehicle
• The trunk
• The front

RKE RMOTE KEY OPERATION

The RKE functionality support interaction with the vehicle over the six SKD buttons. When approaching or leaving your vehicle carrying the key fob, you do not need to point the key fob at your vehicle as you press o button, but you must be within operating range. Radio equipment on o similar frequency con affect the key. If this happens, move the key at least 30 cm away from other electronic devices [phone, laptop, etc).
