3 is a flow chart illustrating a method for securing and maintaining a vehicle according to an exemplary embodiment of the present invention. As shown in FIG. 3 , the method for securing and maintaining a vehicle may include a plurality of steps S30 to S39. In some embodiments, the method of FIG. 3 may be performed by the electronic device 200 of FIG. 2 , and FIG. 3 will be described with reference to FIG. 2 below.

Referring to FIG. 3 , whether or not seating may be detected in step S30 . For example, the seating sensor 230 may generate a third signal SIG3 indicating the occupant's seating when detecting the occupant's seating, and the processing circuit 250 may identify the occupant's seating based on the third signal SIG3. can As shown in FIG. 3 , when the seating of the occupant is detected, step S31 may be subsequently performed.

In step S31, biometric information of the occupant may be obtained. In some embodiments, the processing circuit 250 may drive the biosensor 210 when a seated occupant is detected. For example, the processing circuit 250 may control power to be supplied to the biosensor 210 when a seated occupant is detected, or may set the biosensor 210 to a normal mode. The biometric sensor 210 may detect biometric information of a passenger seated in the driver's seat and may generate a second signal SIG2. The processing circuit 250 may obtain biometric information of the occupant through the second signal SIG2.

In step S32, authentication of the passenger may be attempted based on identification information (ID). For example, the processing circuit 250 may obtain the identification information (ID) by accessing the memory 260, and attempt to authenticate the passenger by comparing the biometric information and the identification information (ID) obtained in step S31. can

In step S33, whether the authentication of the passenger is successful or not may be determined. For example, the processing circuit 250 may determine that the authentication of the occupant is successful if the biometric information obtained in step S31 matches the identification information (ID), while the biometric information obtained in step S31 is the identification information. If it is different from (ID), authentication of the passenger may be determined as failure. As shown in FIG. 3 , if authentication succeeds, step S34 may be subsequently performed, while if authentication fails, step S37 may be subsequently performed.

When authentication of the occupant succeeds, that is, when the occupant is determined to be a valid driver, starting of the vehicle may be allowed in step S34. For example, processing circuitry 250 may permit an action to start the vehicle by an authenticated occupant, such as turning an inserted key or pressing a start button to start the vehicle. In some embodiments, the processing circuit 250 may control the output device 280 to output an output signal OUT informing the passenger of successful authentication of the passenger.

In step S35, it may be determined whether or not the vehicle is started. In some embodiments, when the occupant gets out of the driver's seat before starting the vehicle in a state in which authentication is completed after seating, step S30 may be performed again. For example, the processing circuit 250 may identify that an authenticated passenger has left the driver's seat based on the third signal SIG3 provided by the seating sensor 230 and invalidate the passenger's authentication accordingly. there is. After the authenticated passenger leaves the driver's seat, the processing circuit 250 may reattempt the authentication of the passenger when the same or a different passenger sits back in the driver's seat by performing step S30 again. As shown in FIG. 3 , when the vehicle is started, step S36 may be subsequently performed.

In step S36, the biosensor 210 may be set to power saving mode. For example, the processing circuit 250 may set the biosensor 210 used for authentication of the occupant to a power saving mode when the vehicle is started by the authenticated occupant, and accordingly, the biosensor 210 Power consumption can be reduced. The biosensor 210 may be controlled to consume low power in a power saving mode, or may have zero power consumption because the supplied power is cut off.

If authentication of the occupant fails, that is, if the occupant is determined to be an illegitimate driver, starting of the vehicle may be disallowed in step S37. For example, processing circuitry 250 may block the vehicle from starting even when an unauthorized occupant takes an action to start the vehicle, such as turning an inserted key or pressing a start button.

In step S38, the output signal OUT may be output. For example, the processing circuit 2500 may control the output device 280 to output an output signal OUT informing the passenger of the passenger's authentication failure.

In step S39, a first message may be transmitted to the terminal. For example, the processing circuit 250 transmits a message indicating the authentication failure of the passenger to the central server 120 and/or terminal 130 of FIG. 1 through the communication module 270 in order to inform the outside of the authentication failure of the passenger. 1 message can be provided. Accordingly, the administrator of the central server 120 of FIG. 1 and/or the owner of the terminal 130 can identify that an illegal passenger has boarded the vehicle, and can take appropriate follow-up measures.

4 is a message diagram illustrating a method for securing and maintaining a vehicle according to an exemplary embodiment of the present invention. Specifically, the message diagram of FIG. 4 shows operations of the vehicle 410 and the terminal 420 communicating with each other over time. In some embodiments, operations of vehicle 410 may be performed by an electronic device included in vehicle 410 (eg, 200 of FIG. 2 ).

Referring to FIG. 4 , in step S41 , the vehicle 410 may determine whether the authentication of the occupant has failed. As described above with reference to FIG. 3 , when a passenger sits in a driver's seat, authentication of the passenger may be attempted based on biometric information of the passenger. If the passenger's biometric information is different from the pre-stored identification information (ID), the passenger's authentication may be determined to fail.

In step S42, the vehicle 410 may transmit a first message to the terminal 420, and the terminal 420 may receive the first message from the vehicle 410. As described above with reference to FIG. 3 , the first message may indicate that an illegitimate occupant of vehicle 410 has been seated in the driver's seat.

In step S43, the terminal 420 may transmit a second message to the vehicle 410, and the vehicle 410 may receive the second message from the terminal 420. For example, a user of the terminal 420, that is, a valid driver of the vehicle, may identify that a passenger who has not been registered in advance in the vehicle 410 sits in the driver's seat of the vehicle 410 based on the first message. The user of the terminal 420 may apply an input to the terminal 420 in order to allow a passenger currently in the vehicle 410 to drive the vehicle 410, and the terminal 420 responds to the user's input. A second message may be transmitted to the vehicle 410 . In some embodiments, in order for the user of the terminal 420 to identify the passenger, the first message may include an image generated by photographing the passenger's face.

At step S44, the vehicle 410 may be allowed to start. For example, based on the second message received in step S43, the vehicle 410 may identify that the current occupant is not a pre-registered legitimate driver, but is a driver authorized to drive the vehicle 410 from the legitimate driver. . Accordingly, the vehicle 410 can be started, and the occupant can start the vehicle.

In this released state, the stopped parking state can be identified. As shown in FIG. 5 , when the vehicle is parked or stopped, step S52 may be subsequently performed.

In step S52, it can be determined whether an abnormality has been detected. For example, the processing circuit 250 may drive the abnormality detection sensor 240 and identify whether or not an abnormality has occurred in the vehicle based on the fourth signal SIG4 provided from the abnormality detection sensor 240. .
