This system consists of a Stand alone- type of receicer(SRx) with corresponding a RKE transmitter. SRx has implemented on board with RF generic receiver device The described system is a radio-frequency remote control for central doors locking /
unlocking, trunk release and Panic activity of an automotive vehicle. This system will be a part of the equipment of the HMC TG vehicles. The system is composed of the following ones:
System Operation:
To serve a remote keyless entry system for the HMC TG RKE system. Remote keyless entry function is provided by the RF system of the SRx and the RKE transmitter. The operation of these functions are as follows:
transmitter with 4 buttons (doors locking, door unlocking, and trunk release) Identifier RF Key Start code RF emission Communication Line Host BCM SRx receiver Remote keyless Entry:
The RKE transmitter transmits at 433.92 MHz for ECE ( or 315MHz for NA) 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 car
- Unlock the car
- Unlock the trunk of the car
- Panic C:\Documents and Settings\james_kwon\My Documents\? ? ? ? ? -
