System configuration
Scope of SMART KEY SYSTEM
The System offers the following features:
- passive access for two doors, driver side and passenger side as well as trunk/tailgate
- passive start after interior detection of the SMART KEY FOB (without interior trunk and hat shelf detection)
- LF-RF communication
- passive access trunk/tailgate via the trunk lid switch at the trunk
- max. 4 SMART KEY FOBs can be handled by the system
- communication to the engine management system via a single line interface
- communication to the ESCL via a single line interface
Short description of the SYSTEM
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 user carries a SMART KEY FOB which itself
does not require any conscious actions by the user (e.g. operate a button).
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.
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.
Concept Description
With this concept, it is possible to have a set of interior antennas that
covers the vehicle’s interior and a set of exterior antennas that covers the
vehicle’s exterior.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. Inductive antennas in
and at the vehicle radiate electromagnetic energy.
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 a higher frequency
