VEHICLE REMOTE CONTROL KEY SYSTEM AND SIGNAL PROCESSING METHOD

摘要

A vehicle remote control key system and a method of processing a signal in the system are provided. The system includes a remote control key that is configured to send out a radio frequency (RF) signal that includes an identification (ID) and operation information to remotely control a target vehicle based on a remote control key operation. In addition, a controller is configured to determine whether the ID of the received RF signal is available and perform the remote control when the ID is available. and the controller retransmits the RF signal to a vehicle in the vicinity of the target vehicle when the ID is unavailable and increases a count bit, which stores the number or times of retransmission in a frame, by one when retransmitting the RF signal.
