FUNCTIONAL DESCRIPTION
1 System Components
The KMC GH F/L System is a vehicle remote keyless entry (RKE) system. 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 KMC GH F/L vehicles.
The system is composed of the following ones:
- transmitter with 4 buttons (doors locking, door unlocking, panic, and trunk release)
System Operation:
To serve a remote keyless entry system for the KMC GH F/L 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:
Remote keyless Entry:
The RKE transmitter transmits at 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
