Document Type and Number:
WIPO Patent Application WO/2015/174736
Kind Code:
A1
Abstract:
A smart key device, according to the present invention, comprises: a low frequency (LF) antenna for communicating with a fob key through an LF signal; a communication unit for communicating with a wireless charging device wirelessly charging an electronic device; and a control unit for confirming whether the LF signal is outputted from the LF antenna to the fob key if a wireless charging initiation signal is received from the wireless charging device according to a driver's input, and controlling the transmission of a wireless charging standby command to the wireless charging device through the communication unit if the LF antenna outputs the LF signal. Therefore, a malfunction of the smart key device caused by signal interference can be prevented, in advance, by preventing a simultaneous outputting of signals of low frequency bands outputted by an adjacent smart key device and a wireless charging device.
