SYSTEM OVERVIEW
The immobilizer active antenna is suited to be used in combination with potentially two [X52] BCMs (one from Continental and one from CK) and 1 key module from Renault. System integration with competitor product is not assumed by Continental. Validation for additional combinations can be quoted upon request. The whole immobilizer function is accomplished by the mutual authentication between key and BCM while the active antenna is playing a role of charging transponder in key and data modulation (demodulation) in the communication path. The typical immobilizer system with active antenna can be referenced as below:
Magnetic field generation:
The active antenna contains base station for driven antenna coil which
generates the LF field for charging transponder as well as carrying the
modulated data.
Serial communication with BCM:
The active antenna is connected to BCM via synchronous serial link. LF
communication data is converted to baseband signals by active antenna and
transmitted in half-duplex mode between transponder and BCM on this interface.
The component of IMMO_ANT is to be installed on Vehicle lockset, the IMMO_ANT
will be driven by BCM to generate magnetic filed which can charge TxP and
works as carrier of data transition. In Renault_X52_IMMO vehicle IMMO_ANT has
no function of illumination. the immobilizer circuit contains a voltage
regulator, a serial interface, a base station IC and an LF antenna. The serial
interface is the communication interface for the communication with the BCM.
The BCM sends the data for initialization and authentication to the Base
station IC. The active antenna contains the ABIC1 immobilizer base station IC,
a ceramic resonator for clock generation, and a voltage regulator for
stabilization of power input.It needs to be connected to the BCM for the
communication function as well as to battery supply and ground. The Base
station IC generates the signals for the transmission to the transponder in
the key and drives the antenna. After transmission the base station IC
receives the answer from the transponder and sends the answer to the BCM. The
software in the BCM controls the complete communication.
