SIEMENS Automotive systems Corp. SASCO Page 3 of 5 FUNCTIONAL DESCRIPTION 1 System Components This is a remote keyless entry (RKE) system of a vehicle for TG/EN/BH of HMC. It consists of the Stand alone- type receicer(SRx) which is corresponding the RKE transmitter. SRx has implemented on board with RF generic receiver device The described system is a radio-frequency remote controler for central doors locking / unlocking, trunk release and panic activities. This system will be a part of the equipment of the HMC TG/EN/BH vehicles. The system is composed of the following ones: - transmitter with 3/4 buttons (doors locking, door unlocking, trunk release and panic) *Panic is applied just for 4buttons variant. System Operation: To serve a remote keyless entry system remote keyless entry function is provided by the RF system of the SRx and the RKE transmitter. The functions are operated as below. Remote keyless Entry: The RKE transmitter transmits at 433.92 MHz for Europe ( or 315MHz for NA, CHN) an FSK modulated data signal to the SRx. The RF system of SRx receives this encrypted RF signal. The SRx send the signal to corresponding the host Body control module through single wired K-line bus then the host module broadcasts the requested remote commands to the appropriate control modules in the vehicle through CAN –communication line . In general the following functions are provided: - Lock the doors - Unlock the doors - Release the trunk - Panic Alam (applying just for 4button) RF KeyIdentifierStart codeRFemissionSRxreceiverHostBCM CommunicationLine
