1 is a view for explaining a fingerprint authentication controller 100 according to an embodiment of the present invention. 2 is a block diagram of a fingerprint authentication controller 100 according to an embodiment of the present invention.

The fingerprint authentication controller 100 according to an embodiment of the present invention is inserted into the vehicle system 1 and configured to be detachable and attached.

At this time, it is preferable that the fingerprint authentication controller 100 is designed to be finished so as to feel unity with the vehicle.

As an example, the fingerprint authentication controller 100 may be positioned on a handle for opening and closing a door of a vehicle so that a fingerprint is recognized when the door is opened or closed. As another example, it may be designed and implemented in various directions, such as being inserted into a steering wheel in a vehicle to noise the steering wheel and simultaneously detecting a fingerprint.

At this time, the fingerprint authentication controller 100 operates in a normal mode and performs a general fingerprint authentication function, but when detached, the fingerprint authentication controller 100 can be used as a Fob key.

In one embodiment, the fingerprint authentication controller 100 may be detached only by a registered driver, and is activated with a Fob key only when detached by a registered driver.

That is, the fingerprint authentication controller 100 cannot be initially detached by a third party other than the registered driver, and is not activated with the Fob key even if it is forcibly detached.

The fingerprint authentication controller 100 includes a communication module 110, a fingerprint scanner 120, a memory 130, and a processor 140.

The communication module 110 transmits and receives data to and from the vehicle. The communication module 110 may include both a wired communication module and a wireless communication module.

In this case, when the fingerprint authentication controller 100 is detached from the vehicle, it may be activated by the registered driver with the Fob key, and in this case, of course, it is possible to transmit and receive data to and from the vehicle through a wireless communication module.

On the other hand, even if it is forcibly removed by a third party other than the registered driver, the wireless communication module is activated instead of the power being cut off, and a warning of theft or theft is notified through data transmission/reception with the vehicle and user terminal. I can.

The fingerprint scanner 120 scans a driver's or a third person's fingerprint.

That is, the fingerprint scanner 120 scans a fingerprint of a driver registered in advance so that the vehicle can be driven in a normal mode.

In this case, the general mode refers to a mode in which the owner of the vehicle or the rented driver can perform all actions to control his or her vehicle, such as starting a vehicle, personalization service, payment, and so on.

Meanwhile, the registered driver's fingerprint information may be stored in a fingerprint scanner, but may be stored in a memory for storage security.

In addition, the fingerprint scanner 120 may enable the Fob key to be activated only to the authorized third party by scanning the fingerprint of the third party authorized by the registered driver.

On the other hand, when a fingerprint of an unauthorized third party is scanned, a warning notification of theft or theft may be provided through data transmission/reception with the vehicle and the user terminal.

A program for driving with the Fob key based on the fingerprint scan result is stored in the memory 130, and the processor 140 executes the program stored in the memory 130. Here, the memory 130 collectively refers to a nonvolatile storage device and a volatile storage device that continuously maintains stored information even when power is not supplied.

Magnetic computer storage devices such as NAND flash memory, hard disk drives (HDDs) such as cards, and optical disc drives such as CD-ROMs, DVD-ROMs, etc. I can.

As the processor 140 executes the program stored in the memory 130, when entering a third-party use mode that can be used by a third party from a general mode that is available only to a registered driver, the fingerprint scanner 130 registers it. It checks whether or not the fingerprint of the driver is normally detected, switches to the third-party use mode, and activates the fingerprint authentication controller 100 so that it can be used with the Fob key as it is confirmed that the fingerprint authentication controller 100 is in a detachable state from a built-in state in the vehicle.

In addition, an embodiment of the present invention may provide notification of authentication status or various operation modes through the display unit 150 such as a display or LED.

In addition, when the fingerprint authentication controller 100 is inserted into the vehicle through the charging unit 160 including wired/wireless charging and a battery, charging is performed through wired charging, and charging is performed using various wireless charging functions even in the detached state. It is possible.

Hereinafter, a method of utilizing the fingerprint authentication controller 100 performed in the vehicle system 1 and the fingerprint authentication controller 100 according to an embodiment of the present invention will be described in more detail with reference to FIG. 3.

3 is a flowchart of a method of utilizing a fingerprint authentication controller according to an embodiment of the present invention.

In the method of using a fingerprint authentication controller according to an embodiment of the present invention, first, a user enters a third-party use mode that can be used by a third party from a general mode that is available only to a registered driver (S110).

In an embodiment, in order to enter the third-party use mode, a registered driver may enter the third-party use mode by controlling the navigation or the UI of the cluster in the normal mode state.

By controlling the vehicle navigation or the UI of the cluster, a new fingerprint can be registered or a fingerprint can be deleted, and various setting processes can be performed such as authentication function, Fob function activation, vehicle function activation and restriction setting in the third-party use mode. have.

In another embodiment, a registered driver in the normal mode state may enter the third party use mode as the fingerprint authentication controller 100 is detached from or detached from the fingerprint authentication controller 100.

In addition, it is preferable that a third party use mode can be entered in an emergency state such as a state in which the engine is turned off, a vehicle failure state, and the like, not in the normal mode.

Next, it is checked whether or not the registered driver's fingerprint is normally detected (S120), and if the result is normal, it switches to a third-party use mode (S130).

If, as a result of the verification, it is not the registered driver's fingerprint, the process of requesting a normal fingerprint may be performed again by returning to the entering state of the third party use mode.

Next, as the third party use mode is switched, the detached fingerprint authentication controller 100 is activated to be used as a Fob key (S140).

In one embodiment, in the third party use mode, the detached fingerprint authentication controller 100 operates in the same way as the existing Fob key, and the fingerprint is not registered just by holding the detached fingerprint authentication controller 100. It may be possible to drive a vehicle by a third party.

In one embodiment, the present invention allows the fingerprint of a third party accepted by the registered driver to be recognized through the fingerprint authentication controller 100, and the fingerprint authentication controller 100 detached only to the recognized third party can be used as a Fob key. Can be activated to do so.

That is, in an embodiment of the present invention, an arbitrary third party may be able to use the Fob key by simply detaching the fingerprint authentication controller 100 by a registered driver, and by further reducing the range, the registered driver By allowing a third party's fingerprint to be scanned, only the third party can be activated with the Fob key only when the third party's fingerprint is recognized.

In an embodiment, in a state in which the third party use mode is switched, one or more of a plurality of functions of the vehicle may be activated or restricted by a setting of a registered driver for reasons of security or the like or by a setting registered in advance.

For example, it is possible to activate or limit vehicle performance, that is, speed, media function, seat setting, storage lock, driving distance, speed, location tracking function, etc. through the in-vehicle cluster or the navigation UI.

That is, if the permitted third party is a family member, it is not necessary to restrict the function, but if the valet service employee or a third party is a third party, there may be problems such as theft of a vehicle or leakage of personal information.

In this case, the above problem can be prevented by limiting functions such as limiting the vehicle so as not to travel over a certain distance or limiting the speed of the vehicle to travel over a certain speed.

Meanwhile, according to an embodiment of the present invention, when the driver leaves the seat position, a process of requesting to recognize a fingerprint again may be additionally performed.

For example, in the process of delivering a vehicle to a third party who is a valet service employee in a normal mode state, when a registered driver leaves the seat position, the third party may request a process of recognizing a fingerprint.

If the registered fingerprint authentication is not performed, functions such as vehicle speed and steering wheel manipulation may be restricted.

However, in the state of switching to the third party use mode, the process of recognizing a fingerprint by a registered driver or a third party may be omitted.

As described above, an embodiment of the present invention makes it impossible for a third party to operate in the normal mode, and enables a third party to drive only when the mode is switched to the third party use mode, thereby securing higher security. can do.

In the above description, steps S110 to S140 may be further divided into additional steps or may be combined into fewer steps, according to an embodiment of the present invention. In addition, some steps may be omitted as necessary, or the order between steps may be changed. In addition, even if other contents are omitted, the contents already described in FIGS. 1 to 2 are also applied to the method of utilizing the fingerprint authentication controller of FIG. 3.
