SMART KEY REMOTE CONTROLLER AND LOW POWER OPERATING METHOD OF THE SAME

A low power operating method for a smart key remote controller of a vehicle , wherein the method includes connecting the smart key remote controller to a smart key control system in a vehicle based on a first frequency signal, after the connection, acquiring a vibration detection value through a vibration detection sensor, checking a strength of the first frequency signal (a received signal strength indicator (RSSI)) received after the connection, determining whether the vibration detection value is greater than or equal to a preset vibration value and the strength of the first frequency signal is greater than or equal to a preset signal strength value, and when a determination result is satisfied, activating a module corresponding to a second frequency signal.
