Information related to the destination (H) at the start of the vehicle running and the place information (P) And can be utilized for the above-described navigation destination estimation algorithm. The controller 120 may obtain the user's weight information for easy user identification.

As described above, the vehicle 100 can acquire information related to the number of times of use of the buttons of the driver's seat memory system M and position information of the vehicle convenience apparatus 140 when the specific smart key 200 is used.

8, it is possible to know the frequency of utilization of the smart key 2000 and the buttons of the driver's seat memory system M during a predetermined number of times of sampling. When the number of smart keys 200 provided to one vehicle 100 is several However, since the driver's seat position information suitable for a specific user is determined, the frequency of the button usage of the driver's seat memory system M can be determined, And the type of the smart key 200 may be combined to identify the user.

Information shown in the first column and the second column in FIG. 8 shows information using the buttons of the driver's seat storage system while the user uses the first smart key. Assuming that the user has boarded the vehicle 10 times, the first column uses Button 1 of the driver's seat memory system (M) 5 times and Button 2 5 times, while using the first smart key. The second column uses Button 1, Button 8, and Button 2 twice, using the first smart key. The third column uses the 2nd smart key and the 2nd button 9th and 1st button 1 times. The fourth column uses the 2nd smart key and the 1st button 6th and the 2nd button 4th I used it.

Referring to the table shown in FIG. 8, it is possible to utilize the information of the second and third columns in order to identify a user who uses a specific button while using the specific smart key 200. The information in the first and fourth columns is difficult to identify the user because the number of times using the first button and the second button is similar.

은 2번 버튼을 사용한 횟수를 의미한다. 신뢰도는 정보의 정확도를 의미한다. 도8에 제시하고 있는 정보를 기초로 신뢰도를 계산하면, 두 번째와 세 번째 칸의 신뢰도가 가장 높으며, 이를 기초로 사용자를 식별 할 수 있는 정보를 획득 할 수 있다. Referring to Equation (1), P denotes reliability,

Means the number of times the button 1 is used.

Means the number of times the button 2 is used. Reliability refers to the accuracy of information. When the reliability is calculated based on the information shown in FIG. 8, the reliability of the second and third cells is the highest, and information capable of identifying the user can be obtained based on the reliability.

On the other hand, the user may not use the button of the driver's seat memory system M. In this case, the user identification information can be derived based on the change in the position of the vehicle convenience apparatus 140, rather than the number of times the button is used. For example, if the user 1 moves the seat forward by being small in shape, if the user 1 has the smart key 1 and continuously moves the seat forward, the control unit 120 controls the information of the smart key 1 and the sheets 18L, The user 1 can be identified based on the information for moving the user 1 forward. The positions of the mirrors 14L and 14R or the sheets 18L and 18R desired by a specific user may have an error, so that the positions within a certain range are regarded as the same positions. In addition, the above-described degree of user identification may include weight information measured by the vehicle. The number of methods for identifying the user described in FIG. 8 is only one embodiment of the present invention, and is not limited thereto.

9A and 9B are diagrams of smart keys for performing communication with the vehicle 100 when the number of smart keys 200 is different according to an embodiment.

The communication unit 130 of the vehicle 100 senses the smart key 200 and acquires the authentication information of the smart key 200 when the driver having the smart key 200 approaches the vehicle 100. [ The obtained information is transmitted to the control unit 120 and the control unit 120 may illuminate the emergency light in accordance with the type of the smart key 200. For example, when the user having the first smart key 200a The emergency light can be lighted up twice a long time when the user approaches the smart key 200b and the emergency light can be lighted up four times when the user having the second smart key 200b approaches the smart key 200b. The communication unit 130 can transmit the user identification information to the control unit 120 at the same time that the user opens the door 15L of the vehicle 100. When the door 15L is closed, The position of the seat 18L and the mirrors 14L and 14R can be adjusted by using the button of the driver's seat memory system M. During the position adjustment, The driver can open the door 15 through the unlock button The operation is based on the RF frequency and the operation in which the vehicle 100 senses the smart key 200 is based on the LF frequency and the operation based on the RF frequency can be controlled at a greater distance, The user can open the door of the vehicle 100 by using the unlock button before sensing the smart key 200. In this case the vehicle 100 recognizes the smart key 200 through the LF signal However, it is possible to recognize the smart key 200 based on the RF signal of the smart key 200.

FIG. 9B is a diagram for explaining an operation of recognizing a user based on two smart keys 200 to two vehicles 100. FIG.

Referring to FIG. 9B, two smart keys 200a and 200b may be provided in one vehicle 100. FIG. 9B shows the first smart key 200a held by the driver and the second smart key 200b carried by the passenger. When the vehicle 100 recognizes the second smart key 200b first, it prepares to set the vehicle 100 device 140 of the vehicle 100 in accordance with the second smart key 200b. In one embodiment, the emergency light adapted to the second smart key 200b may be turned on. However, since the driver possesses the first smart key 200b, a problem arises if the set value is set to the second smart key 200b. In this case, the driver holds the first smart key 200a and simultaneously opens the door of the vehicle 100 using the smart key 200 button or the door 15L handle located on the door 15L of the vehicle 100. In this case, (15L). The vehicle 100 can recognize the smart key 200 again at this time and recognize the first smart key 200a again in the embodiment shown in FIG. 8B. Through this process, the vehicle 100 can newly recognize the first smart key 200a in the second smart key 200b.

On the other hand, when unlocking is performed using the smart key 200 button located on the trunk and not on the driver's door 15L and on the passenger's door 15L, The control unit 120 does not assign the ID of the smart key 200 since it is not necessary to adjust the smart key 200. [ Therefore, an operation such as lighting the above-described emergency light is not performed, and an operation of driving the vehicle 100 apparatus 140 based on previously stored information is also not executed.

10-12 are flowcharts according to one embodiment.

10 is a flowchart showing the order in which the control unit 120 acquires the identification information.

Referring to FIG. 10, the vehicle 100 may detect the identification information of the smart key 200 (500). The vehicle 100 that identifies the type of the smart key 200 confirms the locked state of the door 15L after boarding the driver (501). When the user uses the buttons of the driver's seat memory system M after boarding, the matching information is acquired based on the frequency of use of the button and the identification information of the smart key 200 acquired earlier (504). If the user does not use the button of the driver's seat memory system M, the matching information may be obtained (503) based on adjusting the position of the vehicle convenience device 140. Matching information with low reliability among the matching information obtained based on the above-described operation is removed (505). The highly reliable matching information is stored in the storage unit (506).

11 is a flowchart showing a procedure for controlling the vehicle 100 apparatus based on the obtained information.

Referring to FIG. 11, when the smart key 200 approaches the vehicle 100 (600), the smart key 200 and the vehicle 100 are matched (601). Communication between the smart key 200 and the vehicle 100 is possible at the LF or RF frequency. After the smart key 200 and the vehicle 100 are matched, the user is identified based on the information stored in advance and the identification information of the smart key 200 (602). Based on the identified information, the control unit 120 can control the vehicle 100 apparatus (603). The type of the vehicle comfort apparatus 140 is not limited.

FIG. 12 is a flowchart showing a procedure for controlling the vehicle 100 when there are two or more smart keys 200. FIG.

Referring to FIG. 12, the first smart key 200a and the second smart key 200b can simultaneously access the vehicle 100 (700). The first smart key 200a and the vehicle 100 can communicate with each other using the LF or RF frequency and can be unlocked using the first smart key 200a. However, since the user using the unlock button may or may not be driving, the vehicle 100 determines whether or not the driver is the driver holding the second smart key 200b until the door 15L of the vehicle 100 is closed (703). If the second smart key 200b is recognized until the door 15L is closed, the second smart key 200b is matched with the vehicle 100 again (704). In this case, the vehicle convenience apparatus 140 is controlled based on the identification information of the second smart key 200b (705). On the other hand, when the user of the first smart key 200a using the unlock button is the driver, the controller 140 controls the vehicle convenience apparatus 140 based on the identification information of the first smart key 200 (706).

On the other hand, if the unlock button of the smart key 200 is not used, the smart key 200 is matched with the first smart key 200a approaching the vehicle 100 (707). The controller 120 determines whether the user holding the first smart key 200a opens the door 15L of the driver's seat (S708). When the owner of the first smart key 200a opens the door 15L, the device 100 is controlled based on the identification information of the first smart key 200a (709). However, when another user, that is, a user having the second smart key 200 opens the door 15L, the second smart key 200b, not the first smart key 200a, (710). In this case, the control unit 120 controls the vehicle 100 based on the identification information of the second smart key 200b rather than the first smart key 200a (711).
