Description

{SYSTEM FOR AUTOMATIC AUTHENTICATION OF CAR SHARING USER}

The present invention relates to a car sharing user automatic authentication system, and more specifically, to a car sharing user automatic authentication system that automatically performs user authentication between a vehicle and a user terminal when a user approaches a vehicle equipped with a digital tachograph (DTG) terminal, thereby allowing a car sharing service to be provided.

When a user travels or goes on a business trip abroad or to another region; when multiple users want to share a single vehicle through a car-sharing service in the city; when a company that operates vehicles including taxis, trucks, and buses wants to entrust the work of assigning and managing vehicles to drivers; when a user wants to use a variety of vehicles that apply new technologies or have high specifications for a desired period of time, the forms of vehicle use are very diverse and have changed.

For example, when traveling or going on a business trip abroad or to another region, you visit a local car rental company and rent a car for a certain period of time. In this case, you have to visit the rental company directly, sign up for insurance, receive the car key, pick up the car yourself, use it, and also visit yourself to return it, which is very inconvenient.

In addition, as new and diverse business models are developed, the need to share vehicles among people who live and work in similar areas or have similar commuting routes is increasing in urban areas.

However, if you want to share your vehicle with others, there are many and complex issues to deal with, such as costs, insurance, fuel costs, vehicle maintenance, and handing over and receiving the vehicle keys. This situation is an obstacle to the activation of the service.

Meanwhile, business operators who rent out vehicles including trucks, buses, passenger cars, taxis, and two-wheeled vehicles need various management methods for sharing vehicles, but there is no solution yet.

In addition, many domestic and foreign automobile companies are competing to release new cars every year, and users have always had a desire to drive new and good cars. In this case, the newer and better the car, the higher the price that ordinary people cannot afford, so many users use the car by leasing or renting it for a set period of time and paying the cost to the leasing or rental company.

These vehicle leases are usually processed as long-term contracts lasting several years, while vehicle rentals are processed as daily contracts. Therefore, it is very inconvenient for users who want to use a vehicle for a short period of time to use vehicle leases or vehicle rentals.

To solve this problem, services have been recently introduced that allow users to use shared vehicles for short periods of time when needed, make reservations for vehicle use using an app installed on their smartphones without having to visit a specific location and fill out complicated paperwork to lease or rent a vehicle, and easily rent the vehicle from various locations in the city.

However, since the car rental service allows anyone other than the user who made the reservation to use the vehicle by only knowing the specific authentication number provided when making the reservation, there was a problem that the vehicle could be used indiscriminately, and if an accident occurred while the vehicle was being driven by someone other than the user who made the reservation, the insurance would not be processed properly. In addition, if the authentication number used for the rental service was leaked through hacking or other means, there was a high risk that it could be used for crimes as well as vehicle theft.

In particular, the installation of DTG terminals is becoming mandatory for vehicles used for passenger and freight transport, such as buses, trucks, and taxis. The DTG terminal records the vehicle's operating records, including the vehicle's GPS location, speed, braking status, traveled distance, engine revolutions per minute (RPM), and impact amount to the vehicle, in units of seconds, and in the event of an accident, records the vehicle's operating records in units of shorter time (e.g. 0.01 seconds).

The vehicle driving records saved in this way can be analyzed as driving data such as speeding, idling, sudden braking, sudden deceleration, and sudden acceleration, and can be used to correct the driver's driving habits to encourage safe driving, or to increase the efficiency of vehicle operation such as fuel saving.

The above vehicle operation records are required to be regularly and mandatorily submitted to a transportation administration agency such as the Korea Transportation Safety Authority. Accordingly, a communication module is attached to the DTG terminal and the vehicle operation records are submitted to a transportation administration agency such as the Korea Transportation Safety Authority via a control server.

However, the communication module equipped in the above DTG terminal is only used to submit the vehicle operation records to the relevant organizations and is not being used for any other purpose.

Therefore, in the present invention, when a user approaches a vehicle equipped with a DTG terminal, the vehicle and the user terminal automatically perform a communication connection with each other through wireless communication such as Bluetooth, and perform user authentication through an authentication code issued from a vehicle sharing management server according to a vehicle sharing reservation, thereby confirming whether the user who has reserved the vehicle sharing service is the correct one and providing the vehicle sharing service.

In addition, the present invention enables the authentication code provided from the vehicle sharing management server to the DTG terminal and the user terminal to be changed periodically or aperiodically, and, in the process of changing the authentication code, when the vehicle is located in a communication failure area (a shaded area), the user terminal can be used as a relay to change the authentication code of the DTG terminal without the user's intervention.

Next, prior inventions existing in the technical field of the present invention will be briefly explained, and then technical matters that the present invention seeks to achieve differently from the prior inventions will be described.

First, Korean Patent Publication No. 2021-0085706 (July 8, 2021) relates to a method for dispatching a shared vehicle, a method for relocating a shared vehicle, a car sharing method, and a car sharing system suitable therefor, and is a prior art invention relating to car sharing, including: a user terminal which is possessed by a member who is a user who wishes to share a shared vehicle and performs a membership application, a car sharing application, and authentication; a car sharing control server which manages vehicle information of a shared vehicle, manages personal information of users, processes car sharing applications, delivery requests, and ride-sharing requests for the shared vehicle, and manages a parking status and a location-based driving status; and a vehicle terminal which is installed in a shared vehicle and communicates with the car sharing control server through a communication network, obtains location information from a GPS satellite, and provides the current location to the car sharing control server together with the parking status.

That is, the above Korean Patent Publication No. 2021-0085706 describes a method and system for searching for available shared vehicles in real time without reservation and using them, and freely parking and returning them at locations other than bases.

However, since the present invention allows the DTG terminal and the user terminal to perform user authentication through wireless communication such as Bluetooth, and the authentication code used when performing the user authentication can be changed periodically or aperiodically, and the user terminal can be used as a repeater to change the authentication code of the DTG terminal without the user intervening when the vehicle is located in a communication-impaired area (shaded area) when the authentication code is changed, there is a significant difference in configuration between the Korean Patent Publication No. 2021-0085706 and the present invention.

In addition, Korean Patent No. 2325599 (2021.11. 08.) relates to a method and system for a digital key sharing service for vehicles, and is a prior invention regarding a method and system including a digital key registration step in which a management server generates a terminal and vehicle digital key through user authentication in response to a request for digital key registration through a dedicated app of a mobile terminal, and the mobile terminal stores the terminal digital key in a secure area separated from the general area, and a digital key usage step in which, when the mobile terminal approaches or tags the vehicle, an authentication token is generated using the terminal digital key stored in the secure area, and the vehicle device operates the vehicle digital key registered from the management server to verify the authentication token, thereby locking or unlocking the vehicle door.

That is, the above Korean registered patent No. 2325599 describes a method and system that can secure the security of digital keys while improving user convenience by providing a master-slave digital key sharing service that allows setting of access rights for each user using a mobile terminal operated with a general operating system and a security operating system.

On the other hand, the present invention performs user authentication by forming a communication channel between a DTG terminal and a user terminal, and an authentication code used for user authentication can be changed periodically or aperiodically, and the authentication code of the DTG terminal can be changed by utilizing the user terminal as a repeater without the user intervening when the vehicle is located in a communication-impaired area (a shaded area), so that the technical configuration of the Korean Patent No. 2325599 and the present invention are clearly different.

The present invention was created to solve the above problems, and the purpose of the present invention is to provide a vehicle sharing user automatic authentication system that automatically performs user authentication through wireless communication including Bluetooth between the vehicle and the user terminal when the user approaches a vehicle equipped with a DTG terminal, thereby allowing the user to receive vehicle sharing services.

In addition, another purpose of the present invention is to provide a vehicle sharing user automatic authentication system that allows use of a vehicle to be restricted by changing only the authentication code of the DTG terminal while leaving the authentication code of the user terminal as it is during the process of changing the authentication code for using the vehicle sharing service on the DTG terminal and the user terminal in the vehicle sharing management server.

In addition, the vehicle sharing user automatic authentication method is characterized in that, when the vehicle sharing management server transmits the changed authentication code to the vehicle sharing user automatic authentication device and the DTG terminal to update each, the authentication code stored in the vehicle sharing user automatic authentication device is left as is, and only the authentication code of the DTG terminal is updated, thereby restricting the use of the vehicle.

In addition, the vehicle sharing user automatic authentication method is characterized by further including a vehicle sharing reservation step in which the user terminal confirms vehicle information available for vehicle sharing service use provided from the vehicle sharing management server, provides reservation data including usage time, cost, payment method, pick-up location, and return location input by the user to the vehicle sharing management server, and performs a vehicle sharing reservation.

In addition, a vehicle sharing user automatic authentication device according to one embodiment of the present invention includes a first receiving unit that receives an authentication code considering a vehicle and a user terminal of a user who will use the vehicle from a vehicle sharing management server; and a user authentication unit that performs user authentication with a DTG terminal equipped in the vehicle by the user's user terminal; and is characterized in that it enables communication connection between the user terminal and the DTG terminal and enables the user to drive the vehicle through the authentication code.

In addition, the vehicle sharing user automatic authentication device further includes a first communication unit for connecting the DTG terminal equipped in the vehicle and the user terminal of the user through short-range communication; and the first communication unit is characterized by including forming a communication channel through Bluetooth pairing with the DTG terminal located at a close distance from the vehicle sharing user automatic authentication device.

In addition, the vehicle sharing management server is characterized in that, when transmitting the changed authentication code to the vehicle sharing user automatic authentication device and the DTG terminal to update each, the authentication code stored in the vehicle sharing user automatic authentication device is left as is and only the authentication code of the DTG terminal is updated, thereby restricting the use of the vehicle.

In addition, the vehicle sharing user automatic authentication device is characterized by further including a vehicle sharing reservation unit that performs a vehicle sharing reservation by providing reservation data including usage time, cost, payment method, pick-up location, and return location input by the user who has confirmed vehicle information available for vehicle sharing service provided from the vehicle sharing management server to the vehicle sharing management server.

In addition, a vehicle sharing user automatic authentication system according to one embodiment of the present invention includes a vehicle sharing user automatic authentication device; a DTG terminal; and a vehicle sharing management server; wherein the vehicle sharing user automatic authentication device receives an authentication code from the vehicle sharing management server that takes into account a vehicle and a user terminal of a user who will use the vehicle, and performs user authentication with the DTG terminal using the user terminal, thereby enabling communication connection between the user terminal and the DTG terminal and allowing the user to drive the vehicle through the authentication code.

According to the vehicle sharing user automatic authentication system of the present invention as described above, when a user who has reserved a vehicle sharing service receives a vehicle at a predetermined location, the DTG terminal and the user terminal form a communication channel between each other through wireless communication such as Bluetooth at a close range, and the DTG terminal receives an authentication code from the user terminal to perform user authentication, thereby confirming whether the user who has reserved the vehicle sharing service is correct, thereby preventing a user other than the person who has reserved the vehicle from indiscriminately using the vehicle or having the vehicle stolen.

In addition, the present invention has the effect of maximally suppressing vehicle theft due to authentication code leakage or hacking by periodically or aperiodically changing the authentication code for using the vehicle sharing service provided from the vehicle sharing management server to the DTG terminal and user terminal.

In addition, the present invention, when a vehicle is located in a communication-impeded area (i.e., a shadow area) such as a tunnel or underground and normal communication is not possible during the process of transmitting an authentication code for use of a vehicle sharing service from a vehicle sharing management server to a DTG terminal and a user terminal, by changing the authentication code by communicating with the DTG terminal in a state in which the user of the user terminal cannot intervene, not only can the authentication code be smoothly changed, but also there is an effect in which no error occurs in user authentication using the authentication code.

In addition, the present invention has the effect of enabling emergency use of a vehicle to be restricted when the vehicle leaves a designated area or is used for crimes, by changing only the authentication code of the DTG terminal without changing the authentication code of the user terminal during the process of changing the authentication code for using the vehicle sharing service in the DTG terminal and the user terminal in the vehicle sharing management server.

Hereinafter, preferred embodiments of the vehicle sharing user automatic authentication system of the present invention will be described in detail with reference to the attached drawings. The same reference numerals presented in each drawing represent the same members. In addition, specific structural and functional descriptions of the embodiments of the present invention are merely illustrative for the purpose of explaining embodiments according to the present invention, and unless otherwise defined, all terms used herein, including technical or scientific terms, have the same meaning as generally understood by a person having ordinary skill in the art to which the present invention belongs. Terms such as those defined in commonly used dictionaries should be interpreted as having a meaning consistent with the meaning they have in the context of the related art, and are preferably not interpreted in an ideal or excessively formal meaning unless explicitly defined herein.

FIG. 1 is a drawing for explaining the configuration of a vehicle sharing user automatic authentication system according to one embodiment of the present invention.

As illustrated in FIG. 1, the present invention comprises a vehicle sharing user automatic authentication device (100), a DTG terminal (200), a vehicle sharing management server (300), a database (400), etc.

The above vehicle sharing user automatic authentication device (100) refers to an app installed on a user terminal such as a smartphone or tablet PC.

At this time, the vehicle sharing user automatic authentication device (100) is not implemented in the form of an app on a user terminal such as a smartphone, but is configured as an independent wearable device so that the user can wear it on a body part or carry it around.

The above-described vehicle sharing user automatic authentication device (100) communicates with the vehicle sharing management server (300) through a network, and allows the user to make a reservation related to vehicle sharing. That is, a user who has confirmed vehicle information that can use the vehicle sharing service provided by the vehicle sharing management server (300) can transmit reservation data including the usage time, cost, payment method, pick-up location, and return location input or selected to the vehicle sharing management server (300) to make a reservation for a shared vehicle.

In addition, the vehicle sharing user automatic authentication device (100) receives and stores an authentication code according to a vehicle sharing reservation from the vehicle sharing management server (300).

At this time, the authentication code provided by the vehicle sharing management server (300) is generated by considering the vehicle used for vehicle sharing and the user terminal of the user who will use the vehicle, and can perform the role of a smart key that can unlock the vehicle or start the engine, and is also provided simultaneously to the DTG terminal (200) equipped in the vehicle to be used by the user together with the vehicle sharing user automatic authentication device (100).

Thereafter, when a user carrying the vehicle sharing user automatic authentication device (100) approaches a vehicle parked at a designated location at a reserved time, a communication connection is established between the vehicle sharing user automatic authentication device (100) and the DTG terminal (200) equipped in the vehicle. At this time, it is preferable that the communication connection between the vehicle sharing user automatic authentication device (100) and the DTG terminal (200) is performed through Bluetooth pairing using BLE (Bluetooth Low Energy), and it is to be noted that various communication methods such as Zigbee and beacon can be applied in addition to this.

Next, the vehicle sharing user automatic authentication device (100) transmits the authentication code provided from the vehicle sharing management server (300) to the DTG terminal (200), and the authentication code received from the vehicle sharing user automatic authentication device (100) at the DTG terminal (200) is compared with the authentication code provided from the vehicle sharing management server (300) and stored to check whether they match, and if the authentication codes match as a result of the check, the user authentication is completed to check whether the user who made the vehicle sharing reservation is correct. When the user authentication is completed in this way, the user can unlock the vehicle, start the engine, and drive.

By performing user authentication using the user terminal owned by the user and the DTG terminal equipped in the vehicle, the vehicle can be prevented from being used indiscriminately or illegally because the person making the reservation is different from the actual user. In addition, there is no need to prepare separate equipment for user authentication, and normal insurance processing can be performed even if an accident occurs while the vehicle is being driven.

Meanwhile, it is preferable to use the phone number of the user terminal for communication connection between the vehicle sharing user automatic authentication device (100) for using the vehicle sharing service and the DTG terminal (200), and to use an authentication code for user authentication that has performed a vehicle sharing reservation. However, it is also possible to perform communication connection or user authentication through an authentication code, the phone number of the user terminal, the user's driver's license, or a combination thereof.

In addition, the above authentication code may use authentication codes with different depths or multiple authentication codes depending on the user's level of use of the shared vehicle.

Here, using authentication codes with different depths means that, for example, when opening a car door or trunk, the authentication code used for user authentication (i.e., the authentication code provided by default according to the car sharing reservation) is used, and when starting the car, an authentication code that includes license information in addition to the authentication code is used. In other words, an authentication code with a deeper depth (e.g., number of bits) is used depending on the importance of the car use.

Additionally, using multiple authentication codes means using different authentication codes for opening doors or trunks, starting the engine, etc.

In addition, the vehicle sharing user automatic authentication device (100) can perform vehicle sharing registration on the vehicle sharing management server (300). That is, a vehicle owner can perform vehicle sharing registration to allow others to use his or her vehicle through vehicle sharing, or a company that operates vehicles including taxis, trucks, and buses can perform vehicle sharing registration to entrust the task of assigning and managing vehicles to drivers.

The above DTG terminal (200) is a device mounted on a vehicle to record and store in real time the vehicle operation record including the speed, location information (GPS), braking, travel distance, engine revolutions per minute (RPM), impact amount to the vehicle, or a combination thereof, when the vehicle is being operated. At this time, the vehicle operation record recorded and stored in real time according to the vehicle operation can be regularly submitted to a traffic administration agency such as the Korea Transportation Safety Authority through a communication means owned by the vehicle.

In particular, when a user possessing the vehicle sharing user automatic authentication device (100) approaches the vehicle, the DTG terminal (200) performs a communication connection between the two via wireless communication and performs user authentication using an authentication code provided from the vehicle sharing management server (300).

This is one of the main features of the present invention. In the present invention, when a user receives a vehicle at a predetermined location, a communication channel is formed between the vehicle sharing user automatic authentication device (100) and the DTG terminal (200). Then, the DTG terminal (200) compares an authentication code provided from the vehicle sharing user automatic authentication device (100) through the communication channel with a previously stored authentication code to confirm whether the user who has reserved the vehicle sharing is correct, and allows the vehicle to be used based on the confirmed user authentication status.

In addition, the DTG terminal (200) may receive information about the phone number of the user terminal together with the authentication code from the vehicle sharing management server (300). In this case, when the user approaches the vehicle location to receive the reserved vehicle, the DTG terminal (200) receives the phone number of the user terminal broadcast from the user terminal, compares it with the phone number of the previously registered user terminal, and performs a communication connection (e.g., Bluetooth pairing) with the user terminal depending on whether or not they match. In other words, a specific vehicle (DTG terminal) can access one of a number of user terminals (i.e., a vehicle sharing user automatic authentication device installed in the form of an app) through short-range communication. In this way, a communication connection must first be established between the vehicle sharing user automatic authentication device (100) and the DTG terminal (200) before user authentication can be performed using the authentication code provided from the vehicle sharing management server (300).

Meanwhile, unlike the method described above, the user terminal (i.e., the vehicle sharing user automatic authentication device) may receive information about the DTG terminal from the vehicle sharing management server (300) in addition to the authentication code. In this case, when the user approaches the vehicle to receive the reserved vehicle, the vehicle sharing user automatic authentication device (100) scans the peripheral equipment by entering information about the DTG terminal, and performs a communication connection with the DTG terminal (200) of the vehicle. In other words, a specific user terminal (i.e., the vehicle sharing user automatic authentication device installed in the form of an app) can access one of a number of vehicles (DTG terminals) through short-range communication. After the communication connection is established between the vehicle sharing user automatic authentication device (100) and the DTG terminal (200), user authentication using the authentication code can be performed.

That is, the communication connection (communication session connection) through Bluetooth pairing between the vehicle sharing user automatic authentication device (100) and the DTG terminal (200) can be selectively performed with the DTG terminal (200) as a master or with the vehicle sharing user automatic authentication device (100) as a master depending on the usage environment of the vehicle sharing service.

The above vehicle sharing management server (300) is a server computer operated directly or by a business operator providing a vehicle sharing service. When a vehicle sharing service is reserved from the vehicle sharing user automatic authentication device (100), it generates an authentication code according to the vehicle sharing reservation and transmits and stores the generated authentication code to the vehicle sharing user automatic authentication device (100) and the DTG terminal (200) equipped in the reserved vehicle.

That is, when a user wishes to pick up a vehicle at a predetermined location, a communication connection is made between the vehicle sharing user automatic authentication device (100) and the DTG terminal (200) using the authentication code, the phone number of the user terminal, etc., and the DTG terminal (200) compares the authentication code provided from the vehicle sharing user automatic authentication device (100) with the authentication code stored in the vehicle sharing management server (300) to confirm whether the user is the one who made the reservation.

At this time, the vehicle sharing management server (300) can periodically or aperiodically change and update the authentication code provided to the vehicle sharing user automatic authentication device (100) and the DTG terminal (200) according to the user's vehicle sharing reservation.

This is one of the main features of the present invention. In order to fundamentally block illegal use due to leakage or hacking of the authentication code generated according to the user's vehicle sharing reservation, the authentication code is changed periodically and the changed authentication code is provided to the vehicle sharing user automatic authentication device (100) and the DTG terminal (200), respectively.

Meanwhile, in a situation where communication is impossible, such as when the vehicle is located in a communication-impaired area (shaded area) such as a tunnel or underground, the vehicle sharing management server (300) can communicate with the DTG terminal (200) by using the vehicle sharing user automatic authentication device (100) as a relay without the user intervening (or without the user being aware of it).

For example, in the process of providing an authentication code that is frequently changed from the vehicle sharing management server (300) to the vehicle sharing user automatic authentication device (100) and the DTG terminal (200), when communication with the DTG terminal (200) of the corresponding vehicle is impossible, the vehicle sharing management server (300) can update the DTG terminal (200) by providing the changed authentication code to the vehicle sharing user automatic authentication device (100) possessed by the user driving the vehicle as a relay and communicating with the DTG terminal (200).

In addition, when the vehicle sharing management server (300) updates by changing the authentication code and providing it to the vehicle sharing user automatic authentication device (100) and the DTG terminal (200), the authentication code of the vehicle sharing user automatic authentication device (100) can be left as is and only the authentication code of the DTG terminal (200) can be changed, thereby restricting the continued use of the vehicle.

For example, a user may be prevented from driving a particular vehicle if it leaves the operator's jurisdiction or country, or if it is used in a crime.

In addition, the vehicle sharing management server (300) can store and manage information on vehicle sharing registration input from the vehicle sharing user automatic authentication device (100) in the database (400). For example, information on vehicle sharing registration by individuals who own vehicles, vehicle sharing registration by companies that operate vehicles such as taxis, trucks, and buses, etc. can be stored and managed.

The above database (400) stores and manages reservation status for each vehicle and user related to the use of vehicle sharing services.

In addition, the above database (400) stores and manages information on vehicle sharing registration by dividing it by individual and company.

FIG. 2 is a diagram for explaining the processing flow of a vehicle sharing user automatic authentication system according to one embodiment of the present invention.

As illustrated in FIG. 2, the vehicle sharing user automatic authentication device (100) initiates a communication connection with the vehicle sharing management server (300) by operating a pre-installed app according to the operation of a user who wishes to make a vehicle sharing reservation.

Next, the vehicle sharing user automatic authentication device (100) displays currently available reservation information (e.g., information such as time, vehicle pick-up location, cost, and payment method) on the screen so that the user can confirm it, performs a vehicle sharing reservation according to the selection of the user who confirmed it, and transmits information about the corresponding vehicle sharing reservation to the vehicle sharing management server (300) (①).

Then, the vehicle sharing management server (300) generates an authentication code used for user authentication according to the vehicle sharing reservation performed by the vehicle sharing user automatic authentication device (100), and transmits the generated authentication code to the vehicle sharing user automatic authentication device (100) and the DTG terminal (200) equipped in the corresponding vehicle through the network, and stores and manages the same (②).

Here, the authentication code provided by the vehicle sharing management server (300) may be changed periodically or irregularly. When the authentication code is changed, the vehicle sharing management server (300) provides the changed authentication code to the vehicle sharing user automatic authentication device (100) and the DTG terminal (200) to update them.

At this time, if it is confirmed that the changed authentication code is not normally provided to the DTG terminal (200) and updated (for example, meaning that an ack signal indicating that the changed authentication code has been received is not returned), the vehicle sharing management server (300) can update the DTG terminal (200) by providing the changed authentication code to the DTG terminal (200) via the vehicle sharing user automatic authentication device (100) (②-1).

Now, in the process of storing and managing authentication codes (including updated changed authentication codes) according to vehicle sharing reservations in the vehicle sharing automatic authentication device (100) and the DTG terminal (200), when a user approaches the vehicle at the time reserved for vehicle use, the vehicle sharing automatic authentication device (100) and the DTG terminal (200) equipped in the vehicle perform wireless communication with each other to form a communication channel (③).

For example, when a user approaches a vehicle location to pick up a reserved vehicle, the DTG terminal (200) receives the user terminal's phone number broadcast from the vehicle sharing user automatic authentication device (100), compares it with the phone number of a previously registered user terminal, and performs a communication connection with the user terminal based on whether or not it matches.

In addition, it is also possible to check a Bluetooth-based device in the vicinity based on information about a DTG terminal of a specific vehicle provided from the vehicle sharing management server (300) in the vehicle sharing user automatic authentication device (100) and perform automatic pairing with a DTG terminal (200) of a specific vehicle to be used for vehicle sharing.

In this way, after the vehicle sharing user automatic authentication device (100) and the DTG terminal (200) are connected to each other through Bluetooth pairing or the like and a communication channel is formed, the authentication code stored in the vehicle sharing user automatic authentication device (100) is transmitted to the DTG terminal (200) (④).

Next, the DTG terminal (200) compares the authentication code received from the vehicle sharing user automatic authentication device (100) with the previously stored authentication code to determine whether they match, and if they match, confirms that the user has been authenticated, unlocks the vehicle, starts the engine, and allows the vehicle to be driven (⑤).

FIG. 3 is a block diagram showing in detail the configuration of a vehicle sharing user automatic authentication device according to one embodiment of the present invention.

As shown in FIG. 3, the vehicle sharing user automatic authentication device (100) is configured to include a first communication unit (110), a vehicle sharing reservation unit (120), a first receiving unit (130), a user authentication unit (140), a first update unit (150), a connection relay unit (160), a memory (170), etc.

When an app for using a vehicle sharing service is executed, the first communication unit (110) communicates with the vehicle sharing management server (300) and transmits and receives data related to vehicle information, reservation data, and authentication codes according to vehicle sharing reservations that can use the vehicle sharing service with the vehicle sharing management server (300).

In addition, the first communication unit (110) enables the user terminal of the DTG terminal (200) equipped in the vehicle to connect via short-range communication when a user using the vehicle sharing service approaches the vehicle. That is, a communication channel is formed through Bluetooth pairing between the vehicle sharing user automatic authentication device (100) and the DTG terminal (200) located in close proximity, and an authentication code for using the vehicle sharing service is transmitted to the DTG terminal (200) via the formed communication channel, thereby enabling user authentication for using the vehicle.

For example, when a user approaches a vehicle to receive a reserved vehicle and then scans the surrounding equipment by entering information about the DTG terminal, the first communication unit (110) can form a communication channel with the DTG terminal (200) of the vehicle. In other words, a communication channel can be formed with the vehicle sharing user automatic authentication device (100) as a master and the DTG terminal (200) through Bluetooth pairing.

At this time, the formation of the communication channel can utilize various wireless communication methods such as Zigbee and beacon in addition to Bluetooth, and when forming the communication channel, the user terminal's phone number, the authentication code, etc. can be used.

In addition, the first communication unit (110) receives data on a changed authentication code related to a vehicle sharing service from the vehicle sharing management server (300) connected to the network through communication and transmits the data to the first update unit (150).

The above vehicle sharing reservation unit (120) displays vehicle information that can use the vehicle sharing service, which is provided from the vehicle sharing management server (300) through the first communication unit (110), on the screen, and provides reservation data including time, cost, payment method, pick-up location, and return location, which is input by a user who confirms the information, to the vehicle sharing management server (300) through the first communication unit (110) to perform vehicle sharing reservation.

The first receiving unit (130) receives an authentication code that takes into account the vehicle and the user terminal of the user who will use the vehicle from the vehicle sharing management server (300) through the first communication unit (110), and stores the received authentication code in the memory (170).

The user authentication unit (140) performs user authentication by providing an authentication code according to a vehicle sharing reservation stored in the memory (170) to the DTG terminal (200). That is, by transmitting the authentication code to the DTG terminal (200) through a communication channel formed through the first communication unit (110), the user of the vehicle can be authenticated.

At this time, the authentication code may be used alone or together with the phone number of the user terminal to establish a communication connection (i.e., establish a communication channel) between the vehicle sharing user automatic authentication device (100) and the DTG terminal (200) and to authenticate the user who can drive the vehicle. In addition, as explained above, authentication codes with different depths (i.e., authentication codes with different bit numbers) or multiple authentication codes may be used depending on the degree of use of the vehicle.

The first update unit (150) receives a periodically or aperiodically changed authentication code from the vehicle sharing management server (300) through the first communication unit (110), and updates the changed authentication code by storing it in the memory (170).

At this time, the user authentication unit (140) transmits the authentication code updated through the first update unit (150) to the DTG terminal (200) through the communication channel formed by the first communication unit (110). Accordingly, the DTG terminal (200) performs additional user authentication based on a comparison with the authentication code provided and updated from the vehicle sharing management server (300), thereby enabling continuous use of the vehicle sharing service.

The above connection relay unit (160) performs a function that allows the vehicle sharing management server (300) to connect to the DTG terminal (200) through a user terminal when the DTG terminal (200) cannot communicate with the vehicle sharing management server (300) or is in a shaded area (e.g., tunnel, underground, etc.) for a long period of time.

For example, when the authentication code changed in the vehicle sharing management server (300) is transmitted to the vehicle sharing user automatic authentication device (100) and the DTG terminal (200) to update each, if communication with the DTG terminal (200) fails and the changed authentication code provided from the vehicle sharing management server (300) is not received, the changed authentication code can be provided to the DTG terminal (200) via the vehicle sharing user automatic authentication device (100).

At this time, the above-mentioned connection relay unit (160) must prevent the user from accessing the data provided by the vehicle sharing management server (300). In addition, it may relay to the DTG terminal (200) in a state in which the user is not aware (e.g., hidden app operation).

The above memory (170) stores various operation programs used in the vehicle sharing user automatic authentication device (100), and stores and manages authentication codes (including updated authentication codes) according to vehicle sharing reservations.

FIG. 4 is a block diagram showing in detail the configuration of a DTG terminal according to one embodiment of the present invention.

As shown in Fig. 4, the DTG terminal (200) is configured to include a vehicle operation record unit (210), a second communication unit (220), a second receiving unit (230), a user authentication processing unit (240), a second update unit (250), a memory (260), etc.

The above vehicle operation record unit (210) stores in real time operation record information regarding speed, location, braking, travel distance, engine status, etc. when the vehicle is being operated, and provides the stored operation record information to a relevant organization (not shown) that manages and supervises the operation record through the second communication unit (220).

The second communication unit (220) forms a communication channel through Bluetooth pairing with the vehicle sharing user automatic authentication device (100) as a user for using the vehicle sharing service approaches, and receives data on an authentication code for using the vehicle sharing service from the vehicle sharing user automatic authentication device (100) through the formed communication channel and transmits the data to the second receiving unit (230).

For example, when the second communication unit (220) receives a user terminal's phone number broadcast from a user terminal (i.e., a vehicle-sharing user automatic authentication device) owned by a user approaching a vehicle location to take over a reserved vehicle, the second communication unit (220) compares the phone number of the user terminal with the phone number of the previously registered user terminal to check whether they match, and if they do, a communication channel can be formed with the user terminal through Bluetooth pairing. In other words, a communication channel can be formed with the vehicle-sharing user automatic authentication device (100) through Bluetooth pairing, with the DTG terminal (200) as a master.

In addition, the second communication unit (220) communicates with the vehicle sharing management server (300) through a network and receives data on authentication codes (including changed authentication codes) for each user related to the vehicle sharing service from the vehicle sharing management server (300).

The second receiving unit (230) receives an authentication code that takes into account the vehicle and the user terminal of each user who will use the vehicle from the vehicle sharing management server (300) through the second communication unit (220), and stores the received authentication code in the memory (260).

In addition, the second receiving unit (230) receives an authentication code for user authentication of the vehicle from the vehicle sharing user automatic authentication device (100) through the communication channel formed by the second communication unit (220), and transmits the received authentication code to the user authentication processing unit (240).

When the authentication code for user authentication is transmitted from the second receiving unit (230), the user authentication processing unit (240) compares it with the authentication code for user authentication of the corresponding vehicle received from the vehicle sharing user automatic authentication device (100), and if the authentication codes match as a result of the comparison, authenticates the user who has reserved vehicle sharing, and provides the authentication result to the vehicle control module (e.g., ECU) so that the vehicle can be driven by opening the vehicle door, starting the vehicle, etc.

In addition, the user authentication processing unit (240) compares the authentication code updated through the second update unit (250) with the updated authentication code received from the vehicle sharing user automatic authentication device (100) through the communication channel formed by the second communication unit (220), and enables continuous use of the vehicle sharing service based on the result of the comparison.

The second update unit (250) receives an authentication code (i.e., an authentication code for each user who has reserved a vehicle sharing service) that is changed periodically or aperiodically from the vehicle sharing management server (300) through the second communication unit (220), and updates the changed authentication code by storing it in the memory (260).

The above memory (260) stores various operation programs used in the DTG terminal (200), and stores and manages authentication codes for each user according to vehicle sharing reservations (including updated authentication codes).

FIG. 5 is a block diagram showing in detail the configuration of a vehicle sharing management server according to one embodiment of the present invention.

As shown in Fig. 5, the vehicle sharing management server (300) is configured to include a third communication unit (310), a vehicle sharing reservation processing unit (320), an authentication code generation unit (330), an authentication code provision unit (340), an authentication code update processing unit (350), a communication failure check unit (360), etc.

The third communication unit (310) communicates with the vehicle sharing user automatic authentication device (100) through a network, and transmits and receives data related to vehicle information, reservation data, and authentication codes according to vehicle sharing reservations that can use the vehicle sharing service with the vehicle sharing user automatic authentication device (100).

In addition, the third communication unit (310) communicates with the DTG terminal (200) equipped in each vehicle through a network, and transmits and receives data related to the authentication code of each user who has made a vehicle sharing reservation to each DTG terminal (200).

In addition, the third communication unit (310) transmits an authentication code that changes periodically or aperiodically based on the control of the authentication code provision unit (340) to each of the vehicle sharing user automatic authentication device (100) and the DTG terminal (200).

The above vehicle sharing reservation processing unit (320) provides vehicle information that can use the vehicle sharing service to the vehicle sharing user automatic authentication device (100) that is connected to communication via the third communication unit (310), performs vehicle sharing reservations for each user based on reservation data input from the vehicle sharing user automatic authentication device (100), and stores and manages information about vehicle sharing reservations in the database (400).

When a specific user makes a car sharing reservation through the vehicle sharing reservation processing unit (320), the above authentication code generation unit (330) generates an authentication code according to the car sharing reservation and transmits the generated authentication code to the authentication code provision unit (340).

The above authentication code providing unit (340) transmits the authentication code generated by the above authentication code generating unit (330) to the vehicle sharing user automatic authentication device (100) and the DTG terminal (200) through the third communication unit (310).

The above authentication code update processing unit (350) changes the authentication code provided to the vehicle sharing user automatic authentication device (100) possessed by the user who has made the vehicle sharing reservation and the DTG terminal (200) equipped in the specific vehicle to be used by the user when the time comes to change the authentication code or when it needs to be changed, and then updates the changed authentication code by providing it to the vehicle sharing user automatic authentication device (100) and the DTG terminal (200) through the third communication unit (310).

Meanwhile, when the authentication code update processing unit (350) updates the changed authentication code by transmitting it to the vehicle sharing user automatic authentication device (100) and the DTG terminal (200), the authentication code stored in the vehicle sharing user automatic authentication device (100) is left as is, and only the authentication code of the DTG terminal (200) is updated, thereby restricting the use of the vehicle.

The above communication failure confirmation unit (360) confirms whether the vehicle sharing management server (300) is in a state where direct communication with the DTG terminal (200) via the network cannot be performed, and if the confirmation result indicates a failure state where communication with the DTG terminal (200) is not connected, information about this is provided to the authentication code update processing unit (350). That is, the authentication code changed by the authentication code update processing unit (350) is first transmitted to the vehicle sharing user automatic authentication device (100) located in close proximity to the DTG terminal (200), and the changed authentication code is provided to the DTG terminal (200) forming a communication channel with the vehicle sharing user automatic authentication device (100).

Next, an embodiment of a vehicle sharing user automatic authentication method according to the present invention configured as described above will be described in detail with reference to FIGS. 6 and 7. At this time, the order of each step according to the method of the present invention may be changed depending on the usage environment or a person skilled in the art.

FIG. 6 is a flowchart showing in detail the operation process of a vehicle sharing user automatic authentication method according to one embodiment of the present invention.

As illustrated in Fig. 6, the vehicle sharing user automatic authentication device (100) performs a communication connection to the vehicle sharing management server (300) via a network according to the user's app execution (S110).

Next, the vehicle sharing user automatic authentication device (100) receives vehicle information that can use the vehicle sharing service from the vehicle sharing management server (300), and provides reservation data including the usage time, cost, payment method, pick-up location, and return location entered by the user who confirmed the information to the vehicle sharing management server (300) to perform a vehicle sharing reservation (S120).

When a vehicle sharing reservation is made by a user through the above step S120, the vehicle sharing management server (300) generates an authentication code that takes into account the vehicle and the user terminal of the user who will use the vehicle (S130), and transmits the generated authentication code to the vehicle sharing user automatic authentication device (100) and the DTG terminal (200) equipped in the vehicle (S140).

After the authentication code according to the vehicle sharing reservation is stored in the vehicle sharing user automatic authentication device (100) and the DTG terminal (200) through the above step S140, when the user approaches the vehicle at the time reserved for vehicle use, it is determined whether a communication connection is established between the vehicle sharing user automatic authentication device (100) and the DTG terminal (200) (S150).

For example, it is determined whether the vehicle sharing user automatic authentication device (100) forms a communication channel with the DTG terminal (200) through Bluetooth pairing with itself as the master, or whether the DTG terminal (200) forms a communication channel with the vehicle sharing user automatic authentication device (100) through Bluetooth pairing with itself as the master.

If a communication channel is formed between the vehicle sharing user automatic authentication device (100) and the DTG terminal (200) as determined in step S150, the vehicle sharing user automatic authentication device (100) transmits an authentication code stored and managed in step S140 to the DTG terminal (200) through the communication channel to request user authentication (S160).

Next, the DTG terminal (200) determines whether user authentication is complete by comparing the authentication code provided from the vehicle sharing user automatic authentication device (100) with the authentication code stored and managed through step S140 (S170).

If the user authentication is not completed as determined through the above step S170, the DTG terminal (200) notifies that the user authentication is not completed and terminates the vehicle sharing service (S171).

In addition, if user authentication is completed as determined through the above step S170, the DTG terminal (200) grants the user control authority to open and close the vehicle door, start the vehicle, etc., so that the user can drive the vehicle (S180).

Meanwhile, the authentication code according to the vehicle sharing reservation stored and managed by each of the vehicle sharing user automatic authentication device (100) and the DTG terminal (200) can be updated periodically or aperiodically by the vehicle sharing management server (300). In other words, the authentication code can be changed and managed periodically to prevent vehicle theft or illegal use due to leakage or hacking of the authentication code.

In this process, when the vehicle is located in a communication-disabled area such as a tunnel or underground and normal communication with the DTG terminal (200) is not possible, the vehicle sharing management server (300) can change the authentication code by using the vehicle sharing user automatic authentication device (100) as a relay to communicate with the DTG terminal (200) while preventing user intervention.

FIG. 7 is a flowchart showing in detail the operation process of updating an authentication code changed to a DTG terminal by relaying it through a vehicle sharing user automatic authentication device according to one embodiment of the present invention.

As shown in Fig. 7, the vehicle sharing management server (300) determines whether the authentication code provided to each of the vehicle sharing user automatic authentication device (100) and the DTG terminal (200) has been changed (S210).

If the authentication code is changed as determined in the above step S210, the vehicle sharing management server (300) provides the changed authentication code to each of the vehicle sharing user automatic authentication device (100) and the DTG terminal (200) (S220), and determines whether the vehicle sharing user automatic authentication device (100) and the DTG terminal (200) have confirmed receipt of the changed authentication code (S230).

If the reception of the authentication code is not confirmed as a result of the judgment in step S230 above, the vehicle sharing management server (300) determines whether the DTG terminal (200) is located in a communication failure area and communication is not possible (S240).

If it is determined in step S240 that communication with the DTG terminal (200) is not possible, the vehicle sharing management server (300) first transmits the changed authentication code to the vehicle sharing user automatic authentication device (100) (S250).

Next, the vehicle sharing user automatic authentication device (100) transmits the changed authentication code received from the vehicle sharing management server (300) to the DTG terminal (200) that has formed a communication channel so that it can be updated (S260).

Meanwhile, although not shown in the above-described Figure 7, when the vehicle sharing management server (300) updates the changed authentication code by transmitting it to the vehicle sharing user automatic authentication device (100) and the DTG terminal (200), the authentication code stored in the vehicle sharing user automatic authentication device (100) may be maintained as is, and only the authentication code of the DTG terminal (200) may be updated, thereby restricting the use of the vehicle.

In this way, the present invention performs user authentication through wireless communication such as Bluetooth between a DTG terminal and a user terminal at close range when a user who has reserved a car sharing service receives the vehicle at a predetermined location, thereby confirming whether the user who has reserved the car sharing service is the one who has reserved it. Therefore, it is possible to prevent other users who are not the person who reserved the vehicle from using it indiscriminately.

In addition, since the present invention changes the authentication code for using the vehicle sharing service provided from the vehicle sharing management server to the DTG terminal and user terminal periodically or aperiodically, vehicle theft due to authentication code leakage or hacking can be prevented to the greatest extent possible.

In addition, the present invention enables the authentication code to be changed by communicating with the DTG terminal in a state where the user of the user terminal cannot intervene when the vehicle is located in a communication failure area during the process of changing the authentication code of the DTG terminal and the user terminal in the vehicle sharing management server, so that the authentication code can be changed smoothly and an error does not occur in user authentication using the authentication code.

In addition, since the present invention can change only the authentication code of the DTG terminal without changing the authentication code of the user terminal in the process of changing the authentication code of the DTG terminal and the user terminal in the vehicle sharing management server, the use of the vehicle can be urgently restricted when the vehicle leaves a certain area or is used for a crime, etc.

As described above, the present invention has been described with reference to the embodiments illustrated in the drawings, but these are merely exemplary, and those with ordinary knowledge in the field to which the technology pertains will understand that various modifications and equivalent other embodiments are possible.
