Problems solved by technology

[0008] The present invention is proposed to solve the above-mentioned problems, and its purpose is to provide a smart key system and its operation method, which can reflect the RF noise intensity confirmed in the area where RF noise is serious to the indoor / outdoor position judgment standard of the remote control key, and can prevent Misjudgment of the presence of the remote control key even when the remote control key registered in the vehicle does not exist, and delays in response to user requests

Embodiment Construction

[0021] The smart key system of the present invention includes: a remote control key; and SMK ECU, when transmitting an existence confirmation request signal to the remote control key, the RSSI value of the received RF noise is measured through the RF communication module, and the measured RSSI value of the RF noise is not When the presence / absence judgment reference value of the remote control key is reached, the RSSI value of a response signal received from the remote control key corresponding to the presence confirmation request signal is measured, and the RSSI value of the measured response signal exceeds the presence / absence value. When judging the reference value, it is recognized that the remote control key registered in the vehicle exists.

[0022] The SMK ECU is characterized in that when the measured RSSI value of the RF noise exceeds the presence / absence judgment reference value of the remote control key, the RSSI value of the RF noise is stored and compared with the ...

Abstract

The present invention relates to a smart key system and an operating method thereof. The smart key system according to the present invention is characterized in that the intensity of RF noise confirmed in an area where RF noise is serious is reflected on the indoor / outdoor position discrimination criterion of the remote control key, and it is possible to prevent registration in the vehicle. Even when the remote control key does not exist, it is judged that there is a remote control key, and there is a slow response to the user's request.

Description

technical field [0001] The present invention relates to an intelligent key system and its operation method, and more particularly, relates to an intelligent key system and its operation method which improve the identification error of a fob (Fob). Background technique [0002] The traditional smart key system takes a long time to confirm the location of the remote control key. The existence confirmation of the remote control key is performed first, and the position confirmation of the remote control key is performed only when the presence of the remote control key is confirmed. [0003] For example, in the case of registering two or more remote keys in the traditional smart key system, it takes a lot of time to confirm the positions of all the registered remote keys. After the user operates the function, it takes several seconds to activate the corresponding function. [0004] Therefore, the user needs to wait for several seconds from the time when the smart key system confi...
