BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a smart key recognition apparatus.
3 is a diagram illustrating a method of transmitting and receiving signals between a smart key recognition apparatus and at least two or more smart keys according to an embodiment of the present invention.
4 is a flowchart illustrating a smart key recognition method according to an embodiment of the present invention.

Hereinafter, an embodiment of a smart key recognition apparatus and method according to the present invention will be described with reference to the accompanying drawings.

In this process, the thicknesses of the lines and the sizes of the components shown in the drawings may be exaggerated for clarity and convenience of explanation. In addition, the terms described below are defined in consideration of the functions of the present invention, which may vary depending on the intention or custom of the user, the operator. Therefore, definitions of these terms should be made based on the contents throughout this specification.

FIG. 2 is a diagram illustrating a schematic configuration of a smart key recognition apparatus according to an embodiment of the present invention. Referring to FIG.

2, the smart key recognizing apparatus 100 includes an RF receiving unit 110, a control unit 120, an LF transmitting unit 130, and a storage unit 140. As shown in FIG.

The RF receiving unit 110 receives an RF signal from the smart key 210 or 220 through an RF antenna (not shown).

The control unit 120 receives one RF signal having the largest RF power (RF power) among the RF signals received through the RF receiving unit 110, and demodulates the RF signal into a digital signal.

The LF transmitting unit 130 periodically transmits LF data to the periphery through an LF antenna (not shown).

The control unit 120 transmits (or broadcasts) LF data through the LF transmitting unit 130 to check the presence or absence of the smart key 210 or 220 in the vicinity.

In this case, the control unit 120 includes RF power setting information for each smart key in the LF data.

For example, the controller 120 does not include the RF output setting information in the LF data when the user previously registered the smart key, or includes the RF output setting information set in default, In case of more than two, RF power setting information is included in LF data according to the number of registered smart keys.

The control unit 120 may manage the RF power setting information according to the smart key in the form of a lookup table.

The storage unit 140 stores RF power setting information for each smart key in the form of a lookup table.

At this time, the RF power setting information for each smart key may be managed as a fixed value without changing the set value (RF output) once. However, in the present embodiment, the battery consumption of the smart key may be reduced, (RF POWER) setting information according to the smart key in order to stably receive the RF signal of the smart key.

For example, the controller 120 may set the RF power setting information of the most recently connected smart key (e.g., frequently used smart key) to the lowest level to reduce battery consumption of the smart key. Or RF power setting information of the most recently connected smart key (for example, a frequently used smart key) to the highest level, thereby stably receiving the RF signal from the smart key.

The controller 120 may rearrange the RF power setting information for each smart key when the smart key that has been recently connected is changed (i.e., the RF output for each smart key may be totally reset).

3 is a diagram illustrating a method for transmitting / receiving a signal between a smart key recognition apparatus and at least two or more smart keys according to an embodiment of the present invention.

In the present embodiment, it is assumed that at least two smart keys 210 and 220 are registered in the smart key recognizing device 100.

Accordingly, the smart keys 210 and 220 receive the LF data from the smart key recognition apparatus 100 and simultaneously RF-respond to the received LF data.

At this time, according to the present embodiment, the LF data includes RF power setting information for each smart key.

Accordingly, each of the smart keys 210 and 220 receiving the LF data changes its own RF output (RF POWER) according to the RF power setting information for each smart key included in the LF data. That is, it responds with an RF output (RF POWER) corresponding to the RF power setting information for each smart key included in the LF data.

Accordingly, the smart key recognition apparatus 100 receives the RF response of the smart key 210 or 220 having the largest RF power (RF POWER).

That is, in the conventional case (when the RF output per smart key is the same), two or more RF responses in the common time slot collide, the smart key recognizer 100 fails to receive the RF response and acquires the RF response in the next time slot . In this embodiment, however, even if at least two smart keys respond at the same time in the common time slot, the RF response of the smart key having the highest RF output can be received, so that the smart key can be quickly recognized in the common time slot.

As described above, since the smart key is quickly recognized, the smart key responsiveness (i.e., reaction rate) is improved and the user's convenience is improved.

4 is a flowchart illustrating a smart key recognition method according to an embodiment of the present invention.

As shown in FIG. 4, the control unit 120 detects at least two smart key registrations (S101).

If at least two smart keys are registered as described above, different RF power setting information is registered in the internal storage unit 140 in the form of a lookup table according to the number of registered smart keys (S102) .

The RF power setting information for each smart key is set differently.

The RF output RF power of the first smart key is set to A (W) and the RF output RF power of the second smart key is set to B (W), assuming that three smart keys are registered, for example, , And the RF output (RF POWER) of the third smart key can be set to C (W).

The size of each RF output is assumed to be A (W) <B (W) <C (W). However, the size of the RF output is not set in the registration order, and it can be set randomly regardless of the registration order.

Even if three smart keys are registered as described above, the user can carry one or two of them, and one of them is mainly used.

Accordingly, the controller 120 detects the most recently connected smart key (S103).

The controller 120 sets the RF power setting information of the most recently connected smart key to the lowest value (S104).

For example, assuming that the most recently connected smart key is the third smart key and the smart key connected the longest ago is the second smart key, the controller 120 sets the RF output (RF POWER) of the third smart key to A (W), the RF output (RF POWER) of the first smart key is set to B (W), and the RF output (RF POWER) of the second smart key is set to C (W).

Also, depending on the option, the RF output setting information of the most recently connected smart key (for example, frequently used smart key) may be set to the highest value.

As described above, the controller 120 updates the RF power setting information for each smart key based on the order in which the smart key is connected (e.g., the most recent connection, the longest connection, etc.) (Or broadcast) the LF signal (or LF data) including the RF power setting information to the surroundings (S105).

Accordingly, even if at least two smart keys respond simultaneously in the common time slot, the controller 120 can recognize the smart key quickly by receiving the RF response of the smart key responding with the highest RF output, thereby improving the user's convenience .

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, I will understand the point. Accordingly, the technical scope of the present invention should be defined by the following claims.
