2 is a diagram illustrating wireless charging of a smart key system according to an embodiment of the present invention.

Referring to FIG. 2, a smart key device 1000 having a wireless charging function may be mounted on a vehicle. The Pawkey 2000 and the smartphone 3000 as a power receiving device can be carried by the driver of the vehicle. For example, when the driver is driving the vehicle, the Pawkey 2000 and the smart phone 3000 are stored in a predetermined position of the vehicle, Can be provided.

Meanwhile, the wireless charging method between the smart key device 1000 having the wireless charging function, the Pawkey 2000, and the smartphone 3000 can use electromagnetic induction method and / or self resonance method. The electromagnetic induction method may use a protocol established by a standard body such as PMA (Power Matters Alliance) or WPC (Wireless Power Consortium).

3 is a conceptual diagram illustrating communication and wireless charging of a smart key system according to an embodiment of the present invention.

3, the smart key device 1000 can communicate with the Paw key 2000, the smart phone 3000, and the tablet PC 4000, and the smart key device 1000 can communicate with the Paw key 2000, The smartphone 3000, and the tablet PC 4000, as shown in FIG.

The smart key device 1000, the Paw key 2000, the smartphone 3000 and the tablet PC 4000 are connected to a power transmission unit having a specification required by the standard groups to implement a wireless charging function, Or a power receiving unit (Power Receive Unit). In addition, each of the smart key device 1000, the POBKEY 2000, the smartphone 3000, and the tablet PC 4000 may be equipped with a communication module suitable for each.

These functions of the smart key system require continuous communication between the smart key device 1000 and the Pov key 2000. In particular, in the case of the passive start function, the smart key device 1000 searches for the Pawkey 2000 and recognizes that the Pawkey 2000 is in the vehicle so that the button can be started.

However, standard organizations such as PMA and WPC have specified that "277 to 357 kHz" and "110 to 205 kHz" should be used as wireless charging frequencies, respectively. However, since the frequency used for the LF communication is approximately "125 to 134 kHz" and the frequency used for the RF communication is approximately "315 to 433 kHz", the smart key device 1000 can wirelessly charge the Povkey 2000 Frequency interference may occur when communicating with each other while providing the same.

[ Although not shown, the smart key device 1000 that can be mounted on a vehicle may further include a configuration for performing a function of the above-described smart key system, for example.

The communication module 101 may communicate with the Pawkey 2000 at a first frequency. Specifically, the communication module 101 can communicate with the Pov key 2000 through LF and RF communication. The smart key device 1000 and the POD key 2000 can perform the functions of the smart key system described above. When the frequency communicating with the pod key 2000 is switched from the first frequency to the second frequency under the control of the control module 105 to be described later, the communication module 101 uses the second frequency, ). ≪ / RTI >

Further, the communication module 101 can communicate with at least one power receiving device.
