In recent years, car-sharing services are rapidly spreading, and car-sharing users and target vehicles are also rapidly increasing.

Car-sharing is a kind of rental car service that rents a desired car for the required amount of time. The biggest difference from a general rental car is that you do not face the vehicle owner or car-sharing service provider, but reserve a vehicle through the service app and use the key. The advantage is that you can open the car door with your smartphone without a lock.

As described above, since the user uses the vehicle without confronting the service provider, it is impossible to exchange the digital key. In addition, in order to control the vehicle door with a smartphone, a vehicle control device is installed in the vehicle, and the vehicle digital key is used to control the vehicle. embedded in the device.

However, when the digital key is placed inside the vehicle as described above, the battery of the digital key is easily discharged due to the continuous communication action between the vehicle and the digital key, and there is a problem in that the risk of theft is high.

In addition, network communication connecting the service app and the server is very important because all processes of the car sharing service are processed through the service app. In other words, in order for the user to use the service smoothly, communication between the user's smartphone and the server is essential. Circumstances may arise that make it impossible.

As shown in FIG. 1 , the vehicle control system includes an application 10 , a service server 20 , and a vehicle 30 .

The application 10 may be a service app installed in a user's terminal (hereinafter, referred to as a user terminal) using a vehicle rental service so that the user can control the vehicle during the rental period. A user may receive a service app from an external server such as an App Store and install it on his/her terminal.

Here, the user terminal may be connected to the service server 20 or the vehicle 30 through a network such as a mobile phone, a smart phone, a personal digital assistant (PDA), a portable multimedia player (PMP), a tablet PC, etc., and includes a camera and may be any type of handheld-based wireless communication device capable of input/output of various information through the screen. All operations of the application 10 related to the vehicle control method based on the virtual code for authentication of the present invention, which will be described below, may be equally performed in the user terminal in which the application 10 is installed.

The service server 20 may be a server that provides a vehicle rental service or a server that provides a user authentication solution using a virtual code for authentication. According to an embodiment, the service server 20 may collect various vehicle data generated while a user using a vehicle rental service operates a vehicle during a vehicle rental period.

The vehicle 30 is a vehicle rented by a user for a specific period (rental period), and during the rental period, the vehicle 30 may be controlled according to various control request signals received from the application 10 installed in the user terminal.

The vehicle 30 may include a vehicle on/off control device 32 , a signal output control device 34 , and an OBD terminal 36 .

The vehicle on/off control device 32 may be a device mounted inside the vehicle 30 and connected to the OBD terminal 36 inside the vehicle 30 .

The vehicle on/off control device 32 may transmit various vehicle data generated while the user who has rented the vehicle uses the vehicle to the service server 20 . Through this, the service server 20 may check how the user is using or has used the vehicle 30 .

The vehicle on/off control device 32 may control the vehicle according to various control requests received from the application 10 . Specifically, the vehicle on/off control device 32 may control operations including door opening/closing, trunk opening/closing, window opening/closing, emergency light on/off, and light on/off.

The signal output control device 34 is a device mounted inside the vehicle 30 and connected to the vehicle on/off control device 32 by wire or wirelessly, and the signal output control device 34 maintains the shape of the FOB key therein. It can be stored as is (i.e. without disassembling the FOB key).

The signal output control device 34 receives a control request from an application installed in a specific user terminal so that the digital key located in the signal output control device 34 controls the starting of the vehicle 30 on/off only when user authentication is completed. can do.

According to the embodiment, the signal output control device 34 maintains the external connection blocking operation state as a default value, so that the digital key (FOB key) stored therein sends the first signal (eg, LF signal) from the vehicle 30 . ) may not be received. Then, when the user authentication is completed, the external connection blocking operation of the signal output control device 34 is released, and the digital key (FOB key) receives the first signal (eg, LF signal) sent from the vehicle 30 and , a second signal (eg, an RF signal) is transmitted in response thereto. The ignition of the vehicle may be controlled to be on or off according to the second signal of the digital key (FOB key).

Here, according to an embodiment, the operation of blocking the connection to the outside may be an operation (jamming operation) of blocking a signal output from the vehicle from being transmitted to the inside of the signal output control device.

According to an embodiment, the operation of blocking the connection with the outside may include an operation of blocking the supply of power to the digital key. Specifically, the signal output control device 34 is connected to a battery (eg, a battery) of the digital key (FOB key), and may serve as a switch for controlling the on/off of the power of the battery supplied to the digital key. The signal output control device 34 maintains the power of the battery in the off state by default (to prevent current from flowing), and only allows the power of the battery to be turned on when user authentication is completed (to allow current to flow), and the digital key ( FOB key) to control the starting of the vehicle.

When user authentication is completed, a current flows in the electrode, and accordingly, the power of the digital key is turned on so that the digital key can receive the first signal (eg, LF signal) sent from the vehicle 30 . In addition, the digital key transmits a second signal (eg, an RF signal) in response to the first signal, so that the ignition of the vehicle can be controlled to be on or off according to the second signal of the digital key (FOB key) do.

In this way, selectively operating the digital key through a jamming operation of the signal output control device 34 or power-off of the digital key, if there is no jamming operation or power-off, the digital stored inside the vehicle 30 The key continues to output the second signal in response to the first signal sent from the vehicle 30 (even when there is no control request from the user), and accordingly, the battery of the digital key is quickly consumed and a malfunction occurs. Because there is, it is to prevent such a problem situation from occurring.

The OBD terminal 36 is connected to the vehicle on/off control device 32 to perform operations including vehicle opening/closing, trunk opening/closing, window opening/closing, emergency light on/off, and light on/off from the vehicle on/off control device 32 . A door, a window, a trunk, etc. of the vehicle 30 may be opened or closed by receiving CAN DATA, and an emergency light, a light, etc. may be turned on or off.

Here, the application 10 , the service server 20 , and the vehicle 30 may transmit/receive various information through a communication network (not shown). Specifically, data transmission/reception between the application 10 (more specifically, the user terminal in which the application 10 is installed) and the service server 20 and the service server 20 and the vehicle 30 (more specifically, vehicle on/off control) Data transmission/reception between the device 32) and data transmission/reception between the application 10 (more specifically, a user terminal in which the application 10 is installed) and the vehicle 30 (more specifically, the vehicle on/off control device 32) may be performed through the communication network (not shown).

In this case, as the communication network (not shown), various types of communication networks may be used, for example, wireless LAN (WLAN), Wi-Fi, Wibro, Wimax, High Speed Downlink Packet Access (HSDPA). ) or wired communication methods such as Ethernet, xDSL (ADSL, VDSL), HFC (Hybrid Fiber Coax), FTTC (Fiber to The Curb), and FTTH (Fiber To The Home) can be used. have.

On the other hand, the communication network (not shown) is not limited to the communication method presented above, and may include all types of communication methods widely known or to be developed in the future in addition to the above-described communication methods.

In addition, data transmission and reception between the application 10 (in more detail, the user terminal in which the application 10 is installed) and the vehicle 30 (in more detail, the vehicle on/off control device 32) is performed through short-range wireless communication (for example, , Bluetooth).

In addition, the vehicle on/off control device 32 and the signal output control device 34 may be connected through short-range wireless communication (eg, Bluetooth) to transmit/receive data.

When a user rents a vehicle, the user may be registered in the service server 20 and the vehicle 30 .

According to an embodiment, the application 10 may transmit user identification information to the service server 20 and the vehicle 30 . Here, the user identification information may be a member code given when a user subscribes to the application 10 , but is not limited thereto. Thereafter, the application 10 may transmit authority information to the service server 20 and the vehicle 30 . The service server 20 and the vehicle 30 may complete user registration by matching and storing authority information in an area where user identification information is stored.

When a user subscribes to the application 10 , the application 10 and the service server 20 may store a virtual code generating function for authentication for the corresponding user and start driving. Then, when the user requests a rental for a specific vehicle 30 , a search algorithm corresponding to the virtual code generation function for authentication for the specific user is provided to the specific vehicle 30 to the specific vehicle 30 . can be registered for.

According to an embodiment, the application 10 may transmit user identification information to the service server 20 . Here, the user identification information may be a member code given when a user subscribes to the application 10 , but is not limited thereto. Thereafter, the application 10 may transmit authorization information to the service server 20 . The service server 20 may complete the registration for the user by matching the authority information to the area in which the user identification information is stored. In addition, the service server 20 transmits registration-related data for the user to the vehicle 30 so that the vehicle 30 stores the data so that the user is also registered in the vehicle 30 .

When the user's vehicle rental contract is completed through these processes, the user can use the vehicle 30 . Hereinafter, a process performed when the user uses the vehicle 30 during the rental period will be described in detail.

Referring to FIG. 2 , the user may request control of the door of the vehicle 30 through the application 10 installed in the user terminal ( S110 ).

Then, when a control request for the door of the vehicle is received from the application 10, the vehicle on/off control device 32 verifies the control request (S120), and according to the verification result, the door of the vehicle opening and closing can be controlled (S130).

At this time, the verification is performed in different ways when communication is possible between the user terminal in which the application 10 is installed and the service server 20 and when communication between the user terminal and the service server 20 is impossible. .

According to an embodiment, when communication is possible between the application 10 and the service server 20, it is generated by the service server 20 and transmitted to the application 10 and the vehicle on/off control device 32, respectively. Verification may be performed based on the provided virtual code for authentication.

The user may request a vehicle control request through the application 10 while being separated from the vehicle 30 by a certain distance or more, for example, by selecting “open door”. In this specification, a series of processes performed when the vehicle control request is “door open” is described, but “door closed (closed), “window open/closed”, “trunk open/closed”, “emergency light on” The same process as “door open” may be performed for all vehicle control requests such as “/off” and “light on/off”.

Referring to FIG. 3 , in response to a control request from the application 10 , the service server 20 may generate a virtual code for authentication and provide it to the application 10 and the vehicle on/off control device 32 , respectively ( S1111 and S1112). At this time, the authentication virtual code transmitted to the application 10 is referred to as a first authentication virtual code, and the authentication virtual code transmitted to the vehicle on/off control device 32 is referred to as a second authentication virtual code.

In this case, the service server 20 may serve as a virtual code generating means for authentication.

The service server 20 serves to generate one or more detailed codes based on user identification information.

The virtual code generation function for authentication includes one or more detailed code generation functions. For example, when the virtual code for authentication includes a plurality of detailed codes, the virtual code generating function for authentication generates a plurality of detailed codes by using the plurality of detailed code generating functions and combines the plurality of detailed codes. A first virtual code for authentication is generated by using a code combining function.

In this case, the virtual code for authentication is generated for each unit count by the virtual code generating means for authentication, that is, a dedicated program installed in the service server 20 , and may mean one time password (OTP).

In one embodiment, the service server 20 may use the user identification information as one of the seed data of the virtual code generation function for authentication. As a specific example, the service server 20 uses one detailed code generating function to generate each detailed code by using user identification information as seed data of each detailed code generating function. In this case, the service server 20 may generate each detailed code using a time point or count value at which vehicle control is requested from the application 10 .

In one embodiment, the service server 20 may generate the first code and the second code, including the first function and the second function as the detailed code generation function. At this time, the service server 20 only includes a first function for generating a first code and a second function for generating a second code as a detailed code generating function in order to increase security. Correlation data may not be included.

The service server 20 serves to generate a virtual code for authentication by combining one or more detailed codes using the virtual code generation function for authentication. In an embodiment, the virtual code for authentication is generated by combining a plurality of detailed codes according to a specific rule. The virtual code generation function for authentication includes a rule for combining a plurality of detailed codes (that is, a detailed code combining function). That is, the service server 20 may combine one or more detailed codes using the detailed code combining function included in the virtual code generating function for authentication.

Various methods may be applied as a method of generating one virtual code for authentication by combining a plurality of detailed codes. As an example of the detailed code combination function, the service server 2 may generate the first virtual code for authentication by alternately arranging an N-digit first code and an N-digit second code. Also, as another example, the detailed code combining function may be a function of combining the second code after the first code. As the number of detailed codes included in the authentication virtual code increases, various detailed code combining functions may be generated.

In addition, in one embodiment, when the virtual code for authentication is generated by a combination according to a specific rule of the first code and the second code, the first code and the second code search the storage location of the user identification information in the search algorithm. Each can play a role for For example, the first code sets the starting point of the storage location search, and the second code searches from the starting point to the storage location of the user identification information (ie, the area in which the user identification information is stored) according to a specific search method. Set the path. Thereafter, when the service server 20 provides the first virtual code for authentication normally generated for each unit count, the vehicle on/off control device 32 sets the search path corresponding to the second code from the starting point corresponding to the first code. It is determined that the moved point is an area in which user identification information is stored. A specific method of searching for a storage location of user identification information based on the first code and the second code constituting the virtual code for authentication will be described later.

As an embodiment of the method in which the service server 20 generates a detailed code, the service server 20 generates a new detailed code for each unit count, and accordingly, the service server 20 generates a new authentication virtual code for each unit count. create The virtual code for authentication newly generated for each unit count is not duplicated. Specifically, the service server 20 ensures that the virtual code for authentication newly generated for each unit count is not duplicated during the rental period determined according to the rental contract of a specific user, and is not duplicated between users using the vehicle rental service. can be set.

As a specific embodiment of preventing duplicate generation of virtual codes for authentication, when generating N-digit first or second codes with M characters, the detailed code generating function included in the virtual code generating function for authentication is MN Codes can be generated as a first code or a second code, and each code is matched for each count from an initial time point at which the detailed code generating function is driven. For example, when the unit count is set to 1 second, different MN codes are matched every second from the time when the detailed code generating function is first driven. In addition, if the period using the specific detailed code generation function is set to a time length shorter than the time length corresponding to the MN count (eg, MN seconds when 1 count is 1 second), the first code or the second code is the use period The same code is not generated over and over again. That is, when the count increases as time passes, when the user makes a vehicle control request to the service server 20 at a specific point in time, the service server 20 provides a code value matched to the count corresponding to the specific point in time. It can be generated with 1 code or 2nd code.

Specifically, when using uppercase letters of the alphabet and numbers from 0 to 9 as characters that can be included in the code (that is, using 36 characters), and allocating 6 digits to the first code and the second code, the service server ( 20) may provide 366 codes as the first code and the second code. In this case, the service server 20 may provide the first code and the second code changed for each count by matching each code for each count.

As another specific embodiment for preventing the duplicate generation of the virtual code for authentication, when the use period of the function for a specific user elapses, a function that generates the first code or the second code (that is, the first function or the second function) ) or change the matching relationship between the first code and the second code to generate a virtual code for authentication different from the previous use cycle. When the virtual code for authentication is combined with the first code generated by the first function and the second code generated by the second function, when the first code generation function or the second code generation function is changed, the service server 20 ) may apply a virtual code generation function for authentication that generates a first virtual code for authentication different from the previous period as the order in which the first code or the second code appears differs from the previous use period to the new use period. In addition, the service server 20 prevents the same code as the first virtual code for authentication used in the previous use period from appearing as the first virtual code for authentication of each count in the new use period (that is, generated according to the first function) The first function and the second function may be selected so that the matching relationship between the first code and the second function generated according to the first code and the second function is not included in the matching relationship included in the previous use period in all counts of the new use period) . That is, after the use cycle in which MN codes can be applied once has elapsed, the virtual code for authentication of the new use cycle is not generated by adjusting or updating the virtual code generation function for authentication, which overlaps with the previous use cycle. The creation function can be applied.

In addition, in another embodiment, the virtual code generating function for authentication (or detailed code generating function), any one of a plurality of enumeration rules for arranging M characters in ascending order is applied. That is, the service server 20 may apply various rules for listing M characters in ascending order to the detailed code generation function included in the virtual code generation function for authentication. For example, a listing rule that lists uppercase letters of the alphabet in ascending order is A, B, C,… , can be in the order of Z, A, C, B,… , may be in the Z order. As the listing rules are different in the virtual code generating function for authentication, the order in which the codes are matched for each count is changed from the initial time when the virtual code generating function for authentication is driven.

In the above description, the service server 20 generates the virtual code for authentication, but in more detail, the virtual code for authentication is generated using a dedicated program for generating the virtual code for authentication included in the service server 20. can

Referring back to FIG. 3 , the application 10 may transmit the first virtual code for authentication received from the service server 20 to the vehicle on/off control device 32 ( S1113 ).

The vehicle on/off control device 32 may perform verification using the first virtual code for authentication received from the application 10 and the second virtual code for authentication received from the service server 20 . At this time, according to the embodiment, when the vehicle on/off control device 32 receives the second authentication virtual code from the service server 20 , the control information corresponding to the vehicle control request by the user terminal 20 is provided. can be received together. Alternatively, according to an embodiment, when the vehicle on/off control device 32 receives the first authentication virtual code from the user terminal 10 , the control information corresponding to the vehicle control request by the user terminal 20 is also included. may receive. Alternatively, according to an embodiment, the virtual code for authentication generated by the service server 20 may be generated using not only user identification information but also control information.

That is, the vehicle on/off control device 32 may serve as a virtual code verification means for authentication. The vehicle on-off control device 32 determines whether the first authentication virtual code and the second authentication virtual code match, and the first authentication virtual code and the second authentication virtual code match. If it is determined, opening and closing of the door of the vehicle may be permitted.

Specifically, the vehicle on/off control device 32 extracts user identification information from each of the first virtual code for authentication and the second virtual code for authentication, and performs user authentication through whether the extracted user identification information matches each other. can be done

In one embodiment, the vehicle on/off control device 32 receives a user authentication request by receiving the first authentication virtual code and the second authentication virtual code generated by the dedicated program (the service server includes the dedicated program). .

The vehicle on/off control device 32 serves to extract one or more detailed codes included in the first virtual code for authentication and the second virtual code for authentication, respectively.

In one embodiment, the vehicle on/off control device 32 includes a detailed code combining function included in the virtual code generating function for authentication. Accordingly, when the first virtual code for authentication and the second virtual code for authentication each include a plurality of detailed codes, the vehicle on/off control device 32 applies the detailed code combination function to obtain the first authentication virtual code and the second authentication code. 2 It is possible to extract a plurality of detailed codes from the virtual code for authentication. For example, when generating a virtual code for authentication in which two detailed codes (ie, a first code and a second code) are combined in the service server 20 , the vehicle on/off control device 32 is configured for the first authentication The first code and the second code may be separated from each other by applying a detailed code combination function in each character array of the virtual code and the second virtual code for authentication.

The vehicle on/off control device 32 performs a role of searching for user identification information in a search algorithm based on one or more extracted detailed codes. Here, the search algorithm is matched to the authentication virtual code generation function used when the service server 20 generates the authentication virtual code. Various methods may be applied as a method of searching the storage location of user identification information based on each detailed code in the vehicle on/off control device 32 . In order for the vehicle on/off control device 32 to search for a storage location based on a plurality of detailed codes, a correlation may be included between the detailed codes.

Here, the storage location means a point (count) on the track corresponding to the time when registration is requested by the user. That is, when a track for a corresponding user is driven in the vehicle on/off control device 32 and registration is requested by a specific user at a specific time, a count corresponding to the corresponding time (ie, the registration time from the last driving time of the track) The corresponding user identification information is stored in the elapsed count) and registered. In addition, in the area where the corresponding user identification information is stored, the permission information of the corresponding user is matched and stored.

More specifically, when the user completes the subscription to the application 10, the driving of the track for the corresponding user starts, and when the user requests registration for car rental after a certain time has elapsed after the subscription, at the time of the registration request on the track User identification information is stored at the corresponding point, and registration is completed. After the corresponding vehicle band contract is over, if the user wants to rent a second vehicle after that, the user identification information is stored at the point corresponding to the second registration request time on the same track for the user terminal 10 to complete the registration. can

When the virtual code for authentication consists of the first code and the second code, in an embodiment having a correlation between the detailed codes, the vehicle on/off control device 32 determines a search start point corresponding to the first code and , a point moved along the search path corresponding to the second code from the search start point may be found as a storage location of the user identification information. That is, the detailed code may include a first code for setting a search start point and a second code for setting a search path from the search start point to a storage location of the user identification information according to a specific search method. have.

In addition, in another embodiment, as the service server 20 provides a new authentication virtual code for each unit count, the vehicle on/off control device 32 is based on the first code and the second code that are changed for each count. It is possible to search the storage location of user identification information by setting the search start point and search path.

Also, as another embodiment, the vehicle on/off control device 32 may include a search algorithm to find a storage location of the user identification information using a plurality of detailed codes having a correlation. The search algorithm is an algorithm that makes it possible to search for a storage location (area where user identification information is stored) when each detailed code included in the virtual code for authentication is applied, and is used when the service server 20 generates the virtual code for authentication. It matches the virtual code generation function for authentication.

For example, when the virtual code for authentication includes a first code for determining a search start point of a storage location and a second code for suggesting a direction of a storage location from the search start point, the search algorithm corresponds to the first code. It is an algorithm that adjusts so that when a direction corresponding to the second code is indicated at a point, a storage location matching the registration time of the user is placed at the corresponding location.

As the search algorithm is used, the vehicle on/off control device 32 may search the storage location of the user identification information even if the first code and the second code included in the virtual code for authentication are changed. Various methods may be applied to the search algorithm, and specific examples will be described later. However, the search algorithm is not limited to the example described later.

For example, referring to FIG. 4 , the search algorithm is a k-shaped (k is MN) moving along a track in which MN codes corresponding to the first code are listed, and the vertices of the k-shaped are on the first code track. When the code moves while corresponding to the point where the code is arranged, each vertex of the k-shaped is matched with the storage location of the user identification information, and the point where the first code track (ie, the first track) and the k-shaped corresponds is the first code It may be a starting point for searching a storage location corresponding to . At this time, the vehicle on-off control device 32 may apply the k-shaped rolling movement so that the vertices of the k-shaped are in contact with the point corresponding to the extracted first code. Through this, the vehicle on/off control device 32 controls the angle corresponding to the second code at the position on the first track in which the k-gon is in contact (for example, a specific angle obtained by dividing 180 degrees into MN pieces to face the vertex of the k-gon). ), it is possible to search for the vertices of the k-shape, which is a storage location in which user identification information corresponding to the virtual code for authentication is stored.

Specifically, as shown in FIG. 4, the vehicle on-off control device 32 moves the k-shaped to a point corresponding to the first code (that is, each vertex of the k-shaped and each point on the track in turn contact each other) move). Thereafter, the vehicle on/off control device 32 searches for a vertex corresponding to the storage location of the user identification information by indicating the angular direction corresponding to the second code.

When the user identification information is searched by the vehicle on/off control device 32 using the first and second codes of the first virtual code for authentication and the second virtual code for authentication in the search algorithm, respectively, the two It is determined whether or not the user identification information of the two dogs matches. When two pieces of user identification information match, it is determined that user authentication is complete, and an operation for door opening/closing control can be performed.

Specifically, if the verification is successful, the vehicle on/off control device 32 inputs the door opening/closing related CAN data corresponding to the received control information to the OBD terminal 36 inside the vehicle 30 to control the vehicle. The door can be opened and closed.

According to an embodiment, when communication between the application 10 and the service server 20 is impossible, based on the authentication virtual code generated by the application 10 and provided to the vehicle on/off control device 32 . Verification may be performed.

A user may request a vehicle control request, for example, by selecting “open door” through the application 10 installed in the user terminal while being separated from the vehicle 30 by a certain distance or more. In this specification, a series of processes performed when the vehicle control request is “door open” is described, but “door closed (closed), “window open/closed”, “trunk open/closed”, “emergency light on” The same process as “door open” may be performed for all vehicle control requests such as “/off” and “light on/off”.

Referring to FIG. 5 , when the application 10 determines that communication between the user terminal and the service server 20 is impossible, the application 10 transmits a door control request signal including control information to the vehicle on/off control device 32 . At this time, the application 10 may generate a virtual code for authentication (S1121), and transmit the generated virtual code for authentication to the vehicle on/off control device 32 (S1122). The vehicle on/off control device 32 may receive the virtual code for authentication (S1123). According to an embodiment, the vehicle on/off control device 32 may receive the control request signal and the virtual code for authentication sequentially, but may also receive the control request signal and the virtual code for authentication together.

In this case, the application 10 may serve as a means for generating a virtual code for authentication.

The application 10 serves to generate one or more detailed codes based on user identification information.

The virtual code generation function for authentication includes one or more detailed code generation functions. For example, when the virtual code for authentication includes a plurality of detailed codes, the virtual code generating function for authentication generates a plurality of detailed codes by using the plurality of detailed code generating functions and combines the plurality of detailed codes. A virtual code for authentication is generated using the code combination function.

In this case, the virtual code for authentication is generated for each unit count by the virtual code generating means for authentication, that is, a dedicated program included in the application 10 , and may mean one time password (OTP).

In one embodiment, the application 10 may use the user identification information as one of the seed data of the virtual code generation function for authentication. As a specific example, the application 10 uses one detailed code generating function to generate each detailed code by using user identification information as seed data of each detailed code generating function. In this case, the application 10 may generate each detailed code using a time point or count value when the user requests vehicle control.

As an embodiment, the application 10 may generate the first code and the second code, including the first function and the second function as the detailed code generation function. At this time, the application 10 only includes a first function for generating a first code and a second function for generating a second code as a detailed code generating function in order to increase security, and the correlation between the first code and the second code Data on relationships may not be included.

The application 10 performs a role of generating a virtual code for authentication by combining one or more detailed codes using the virtual code generation function for authentication. In an embodiment, the virtual code for authentication is generated by combining a plurality of detailed codes according to a specific rule. The virtual code generation function for authentication includes a rule for combining a plurality of detailed codes (that is, a detailed code combining function). That is, the application 10 may combine one or more detailed codes using the detailed code combining function included in the virtual code generating function for authentication.

Various methods may be applied as a method of generating one virtual code for authentication by combining a plurality of detailed codes. As an example of the detailed code combination function, the application 10 may generate a virtual code for authentication by alternately arranging an N-digit first code and an N-digit second code. Also, as another example, the detailed code combining function may be a function of combining the second code after the first code. As the number of detailed codes included in the authentication virtual code increases, various detailed code combining functions may be generated.

In addition, in one embodiment, when the virtual code for authentication is generated by a combination according to a specific rule of the first code and the second code, the first code and the second code search the storage location of the user identification information in the search algorithm. Each can play a role for For example, the first code sets the starting point of the storage location search, and the second code searches from the starting point to the storage location of the user identification information (ie, the area in which the user identification information is stored) according to a specific search method. Set the path. Then, when the virtual code for authentication normally generated for each unit count is provided in the application 10, the vehicle on/off control device 32 moves from the starting point corresponding to the first code along the search path corresponding to the second code. A point is determined as an area in which user identification information is stored. A specific method of searching for a storage location of user identification information based on the first code and the second code constituting the second virtual code for authentication will be described later.

As an embodiment of the method in which the application 10 generates a detailed code, the application 10 generates a new detailed code for each unit count, and accordingly, the application 10 generates a new authentication virtual code for each unit count. . The virtual code for authentication newly generated for each unit count is not duplicated. Specifically, the application 10 is set so that the newly generated authentication virtual code for each unit count is not duplicated during the rental period determined according to the rental contract of a specific user, and is not duplicated between users using the vehicle rental service. can be

As a specific embodiment of preventing duplicate generation of virtual codes for authentication, when generating N-digit first or second codes with M characters, the detailed code generating function included in the virtual code generating function for authentication is MN Codes can be generated as a first code or a second code, and each code is matched for each count from an initial time point at which the detailed code generating function is driven. For example, when the unit count is set to 1 second, different MN codes are matched every second from the time when the detailed code generating function is first driven. In addition, if the period using the specific detailed code generation function is set to a time length shorter than the time length corresponding to the MN count (eg, MN seconds when 1 count is 1 second), the first code or the second code is the use period The same code is not generated over and over again. That is, when the count increases as time passes, when the user makes a vehicle control request through the application 10 at a specific time, the application 10 returns a code value matching the count corresponding to the specific time to the first It can be generated with a code or a second code.

Specifically, if uppercase letters of the alphabet and numbers 0 to 9 are used as characters that can be included in the code (that is, 36 characters are used), and 6 digits are assigned to the first code and the second code, respectively, the application (10 ) may provide 366 codes as the first code and the second code. In this case, the application 10 may provide the first code and the second code changed for each count by matching each code for each count.

As another specific embodiment for preventing the duplicate generation of the virtual code for authentication, when the use period of the function for a specific user elapses, a function that generates the first code or the second code (that is, the first function or the second function) ) or change the matching relationship between the first code and the second code to generate a virtual code for authentication different from the previous use cycle. When the virtual code for authentication is combined with the first code generated by the first function and the second code generated by the second function, when the first code generation function or the second code generation function is changed, the application (10) may apply to the new use cycle a virtual code generation function for authentication that generates a virtual code for authentication different from the previous cycle as the order in which the first code or the second code appears is different from the previous use cycle. In addition, the application 10 prevents the same code as the virtual code for authentication used in the previous use cycle from appearing as the virtual code for authentication of each count in the new use cycle (that is, the first code generated according to the first function and The first function and the second function may be selected so that the matching relationship of the second code generated according to the second function is not included in the matching relationship included in the previous use period in all counts of the new use period). That is, after the use cycle in which MN codes can be applied once has elapsed, the virtual code for authentication of the new use cycle is not generated by adjusting or updating the virtual code generation function for authentication, which overlaps with the previous use cycle. The creation function can be applied.

In addition, in another embodiment, the virtual code generation function for authentication (or detailed code generation function), any one of a plurality of listing rules for arranging M characters in ascending order is applied. That is, the application 10 may apply various rules for listing M characters in ascending order to the detailed code generation function included in the virtual code generation function for authentication. For example, a listing rule that lists uppercase letters of the alphabet in ascending order is A, B, C,… , can be in the order of Z, A, C, B,… , may be in the Z order. As the listing rules are changed in the virtual code generating function for authentication, the order in which codes are matched for each count is changed from the initial time when the virtual code generating function for authentication is driven.

In the above, it has been described that the application 10 generates the virtual code for authentication, but in more detail, the virtual code for authentication can be generated using a dedicated program for generating the virtual code for authentication included in the application 10. .

Referring back to FIG. 5 , the vehicle on/off control device 32 may perform verification using the virtual code for authentication received from the application 10 .

That is, the vehicle on/off control device 32 may serve as a virtual code verification means for authentication. The vehicle on/off control device 32 searches for user identification information based on the received virtual code for authentication, extracts stored authorization information matching the searched user identification information, and corresponds to the extracted authorization information. Opening and closing of the door of the vehicle may be permitted only when the virtual code for authentication is received within a time range.

That is, the vehicle on/off control device 32 permits opening and closing of the door of the vehicle only when the vehicle control request is requested during the user's rental period. That is, even if verification of the virtual code for authentication is completed (that is, even if the request is received from a registered user), vehicle control may not be performed if the request is not requested within the rental period. Since this is a case where communication with the service server 20 is not possible, the vehicle 30 directly determines whether a corresponding request is received within a time range allowed for a specific user. In the case of communication with the service server 20, if the time of the control request from the user is not included in the rental period, the service server 20 may determine this and not generate the authentication virtual code itself. And, when the control request is not received within the allowed time range, the vehicle 30 or the service server 20 may provide a notification to the user terminal informing that the contract period is over.

Specifically, the vehicle on/off control device 32 extracts user identification information from the virtual code for authentication, and determines whether the extracted user identification information matches the information of the user registered in the vehicle 30, and the virtual image for authentication. User authentication may be performed based on whether the code reception time is included in a time range corresponding to the extracted user identification information and the matched authorization information.

In one embodiment, the vehicle on/off control device 32 receives a user authentication request by receiving a virtual code for authentication generated by a dedicated program (the application 10 includes the dedicated program).

The vehicle on/off control device 32 serves to extract one or more detailed codes included in the virtual code for authentication, respectively.

In one embodiment, the detailed code extraction unit (not shown) includes a detailed code combining function included in the virtual code generation function for authentication. Accordingly, when the virtual code for authentication includes a plurality of detailed codes, the vehicle on/off control device 32 may extract a plurality of detailed codes from the virtual code for authentication by applying the detailed code combining function. For example, when generating a virtual code for authentication in which two detailed codes (ie, a first code and a second code) are combined in the user terminal 10 , the vehicle on/off control device 32 is a virtual code for authentication The first code and the second code can be separated from each other by applying the detailed code combination function in the character array of .

The vehicle on/off control device 32 performs a role of searching for user identification information in a search algorithm based on one or more extracted detailed codes. Here, the search algorithm is matched to the authentication virtual code generation function used when generating the authentication virtual code in the application 10 . Various methods may be applied as a method for the storage location search unit (not shown) to search the storage location of the user identification information based on each detailed code. In order for the storage location search unit (not shown) to search for a storage location based on the plurality of detailed codes, a correlation may be included between the detailed codes.

Here, the storage location means a point (count) on the track corresponding to the time when user registration is requested by the user. That is, when a track for a corresponding user is driven in the vehicle on/off control device 32 and registration is requested by a specific user at a specific time, a count corresponding to the corresponding time (ie, the registration time from the last driving time of the track) The corresponding user identification information is stored in the elapsed count) and registered. In addition, in the area where the corresponding user identification information is stored, the permission information of the corresponding user is matched and stored.

More specifically, when the user completes the subscription to the application 10, the driving of the track for the corresponding user starts, and when the user requests registration for car rental after a certain time has elapsed after the subscription, at the time of the registration request on the track User identification information is stored at the corresponding point, and registration is completed. After the contract is over, if the user wants to rent a car for the second time, the registration can be completed by storing the user identification information at a point corresponding to the time of the second registration request on the same track for the user.

In addition, in another embodiment, as the application 10 provides a new authentication virtual code for each unit count, the vehicle on/off control device 32 is based on the first code and the second code that are changed for each count. The storage location of user identification information can be searched by setting the search start point and search path.

Also, as another embodiment, the vehicle on/off control device 32 may include a search algorithm to find a storage location of the user identification information using a plurality of detailed codes having a correlation. The search algorithm is an algorithm that makes it possible to search for a storage location (area where user identification information is stored) when each detailed code included in the virtual code for authentication is applied. It matches the virtual code generation function for authentication.

For example, referring to FIG. 4 , the search algorithm is a k-shaped (k is MN) moving along a track in which MN codes corresponding to the first code are listed, and the vertices of the k-shaped are on the first code track. When the code moves while corresponding to the point where the code is arranged, each vertex of the k-shaped is matched with the storage location of the user identification information, and the point where the first code track (ie, the first track) and the k-shaped corresponds is the first code It may be a starting point for searching a storage location corresponding to . In this case, the storage location search unit (not shown) may apply the k-shaped rolling movement so that the vertices of the k-shaped are in contact with the point corresponding to the first code extracted by the detailed code extraction unit (not shown). Through this, the storage location search unit (not shown) determines the angle corresponding to the second code at the position on the first track where the k-gon is in contact (for example, a specific angle obtained by dividing 180 degrees into MN pieces to face the vertex of the k-gon). ), it is possible to search for the vertices of the k-shape, which is a storage location in which user identification information corresponding to the first virtual code for authentication is stored.

When the user identification information is searched for by using the first code and the second code of the virtual code for authentication in the search algorithm by the vehicle on/off control device 32 , the searched user identification information is the user registered in the vehicle 30 . It is determined whether it is the same as identification information. Then, it is determined whether the reception time of the virtual code for authentication is included within the rental period through the authority information matched to the searched user identification information. If the user identification information is the same and the reception time is within the rental period, it is determined that the user authentication is completed and an operation for door opening/closing control may be performed.

If the verification is successful, the vehicle on/off control device 32 inputs the door opening/closing related CAN data corresponding to the received control information to the OBD terminal 36 inside the vehicle 32 to open and close the door of the vehicle. can make it happen

According to the embodiment, the vehicle on-off control device 32 receives the virtual code for authentication from the application 10 (reception time) and the virtual code for authentication generates a virtual code generation function for authentication in the application 10. It can also play a role of verifying the virtual code for authentication by comparing the generated time (the time of generation) using the .

Referring to FIG. 6 , the vehicle on/off control device 32 determines the generation time of the authentication virtual code generated by the application 10 and the reception time of the authentication virtual code received from the application 10 . It can be determined that the virtual code for authentication is a normal code only when it is within the error range.

Referring back to FIG. 2 , the signal output control device 34 determines whether to release the connection blocking operation with the outside according to the verification result, and the vehicle located inside the signal output control device 34 according to the determination result. The digital key of (30) may control the starting of the vehicle (30) (S140).

Specifically, after the verification is successful, when information on opening/closing of the vehicle door is received from the vehicle on/off control device 32, the signal output control device 34 may release the connection blocking operation with the outside. have. Accordingly, the digital key can control the vehicle start on or off. Here, the operation of blocking the connection with the outside may include an operation of blocking transmission of a signal output by the vehicle to the inside of the signal output control device and an operation of blocking power supply to the digital key.

According to an embodiment, after the verification is successful, the vehicle on/off control device 32 determines the distance between the application 10 and the vehicle 30 based on the signal strength according to the control request, and When the determined distance is within a preset distance, information on opening/closing of the vehicle door may be transmitted to the signal output control device 34 . Accordingly, the signal output control device 34 may release the connection blocking operation with the outside.

At this time, as described above, the jamming operation prevents the digital key from outputting a second signal in response to the first signal sent by the vehicle 30 by interfering with the communication between the digital key and the vehicle 30, Blocking is to keep the power of the digital key in the off state by preventing the current from flowing to the digital key.

Accordingly, in the jamming operation of the signal output control device 34 or the battery power cut-off state, the first signal (eg, LF signal) transmitted by the vehicle 30 is blocked, and the digital key of the vehicle 30 is The first signal is not transmitted. Thereafter, when the jamming operation or blocking of the signal output control device 34 is released by receiving information on door opening and closing from the vehicle on/off control device 32 , the first signal sent by the vehicle 30 is transmitted to the vehicle. It is transmitted to the digital key of 30 , and the digital key of the vehicle 30 outputs a second signal (eg, an RF signal) in response to the first signal to turn on the ignition of the vehicle 30 . Or you can control it off.

In the conventional digital key-related technology, in order to remotely control the vehicle, it is inevitable to dismantle the provided digital key (FOB key), and there is a limitation that network communication between the user terminal and the server is essential. In addition, only functions such as doors and lights of the vehicle can be controlled, and it was impossible to control the start-up according to the manufacturer's policy. However, according to the present invention, without the need to disassemble the digital key (FOB key), the digital key is stored in a bolt device, and functions such as doors and lights can be remotely controlled by mounting the bolt device to the vehicle, and network communication Even in this difficult environment, it is possible to control through user authentication without difficulty, and when user authentication is completed, the digital key can be used within the scope of the manufacturer's policy by controlling the ignition through the digital key stored in the bolt device.

8 is a flowchart of a vehicle control vehicle control method based on a virtual code for authentication according to another embodiment of the present invention.

As shown in FIG. 7 , the vehicle control system includes an application 10 , a service server 20 , and a vehicle 30 .

Since the application 10 and the service server 20 are the same as those described with reference to FIG. 1 , a detailed description thereof will be omitted.

The vehicle 30 is a vehicle rented by a user for a specific period (rental period), and the vehicle 30 may include a signal output control device 34 and an OBD terminal 36 . Since the OBD terminal 36 is the same as that described with reference to FIG. 1 , a detailed description thereof will be omitted. In this case, the signal output control device 34 may refer to the same device as the above-described signal output control device 34 . A detailed description of the signal output control device 34 is the same as that described with reference to FIGS. 1 to 6, and thus will be omitted.

The signal output control device 34 is a device mounted inside the vehicle 30 and connected to the OBD terminal 36, and the signal output control device 34 includes a digital key (more specifically, a FOB key) therein. It can be kept intact (ie without disassembling the FOB key).

In this case, the signal output control device 34 may communicate with the application 10 and the service server 20 through a communication network (not shown). In this case, as the communication network (not shown), various types of communication networks may be used, for example, wireless LAN (WLAN), Wi-Fi, Wibro, Wimax, High Speed Downlink Packet Access (HSDPA). ) or wired communication methods such as Ethernet, xDSL (ADSL, VDSL), HFC (Hybrid Fiber Coax), FTTC (Fiber to The Curb), and FTTH (Fiber To The Home) can be used. have.

The signal output control device 34 may verify the control request from the application 10 , and determine whether to release the connection blocking operation with the outside according to the verification result.

In the above, a vehicle control method through user authentication when a user who rented a vehicle directly uses the vehicle has been described. Hereinafter, a vehicle control method through user authentication when a rented vehicle is used by someone other than the user will be described.

In case of use by others, the case where the user's family uses the vehicle rented by the user, provides a valet service for the vehicle rented by the user, or provides a valet service for the vehicle owned by the user may include, but is not limited to.

According to an embodiment, when the same application as the application installed by the user is installed in a terminal used by another person, the user provides the virtual code for authentication generated in the user's application as the application of the other person, so that the other person can use the vehicle can be made available. In this case, the user and other's terminals may transmit and receive signals or information through short-range communication such as Bluetooth, but the communication method is not limited thereto.

In this way, the virtual code for authentication received as an application of another person is provided to the vehicle on/off control device (or signal output device) of the vehicle, so that the verification of the virtual code for authentication can be performed. And by performing user authentication through verification, the other person can use the vehicle. Since the generation and verification method of the virtual code for authentication is the same as described above, a detailed description thereof will be omitted.

In this case, the virtual code for authentication generated by the user's application may include a fixed virtual code and validity period information. Different fixed virtual codes are generated according to usage types (ie, for valet, family, corporate, etc.), and an expiration period for each fixed virtual code may be set. For example, if a user generates a virtual code for authentication for valet use, others who have been provided with the virtual code for authentication may use the virtual code for authentication and use the vehicle only during the valid period (for example, 3 hours). be able to

According to an embodiment, when the same application as the application installed by the user is not installed in a terminal used by another person, the user provides a registered blank card to another person, and the other person provides the blank card to the vehicle through NFC tagging can be used

Here, the registered blank card means a blank card to which the authority for the control request of the vehicle is granted through the user's application. The vehicle on/off control device (or signal output control device) may receive the control request from the blank card to which the authority is granted through NFC tagging.

As described above, the validity period for the empty card may be set at the time of registering the empty card, and when the validity period expires, the vehicle using the empty card becomes impossible.

That is, when the other person tags the blank card provided by the user through an NFC reader attached to the vehicle (eg, the side of the windshield), the vehicle on/off control device (or signal output control device) inside the vehicle It is possible to generate and verify a virtual code for authentication based on the blank card-related information received from the NFC reader. That is, it is verified whether it is a registered blank card. Since the generation and verification method of the virtual code for authentication is the same as described above, a detailed description thereof will be omitted.

More specifically, the user can keep at least one blank card inside the vehicle, and register the blank card in his/her application whenever necessary (every time using valet). Afterwards, the vehicle on/off control device inside the vehicle generates a virtual code for authentication based on the blank card information (serial number, etc.) received through NFC tagging and performs verification, so that the blank card is the user It is possible to determine whether the card is registered for the vehicle of

For example, if the application is not installed on the terminal of a parking attendant who performs valet parking, a digital key must be handed to perform valet parking, and in this case, a vehicle theft accident may occur. Therefore, in the present invention, by providing the parking agent with the blank card with the validity period set instead of the digital key, the parking agent can use the vehicle only for a limited time.
