The sensor module 300, navigation device 400, braking device 500, steering device 600, etc. may correspond to general configurations required for autonomous driving control.

The self-driving control device 100 groups a plurality of self-driving vehicles based on a blockchain method to create at least one group, and stores vehicle information of each of the plurality of self-driving vehicles in each group. can be shared between autonomous vehicles. At this time, blockchain is a data distribution processing technology that distributes and stores all data subject to management by all objects participating in the network.

The communication unit 110 is a hardware device implemented with various electronic circuits to transmit and receive signals through wireless or wired connections. In the present invention, it performs in-vehicle communication through can communication, etc., and the communication module 200 ), sensor module 300, navigation device 400, braking device 500, steering device 600, etc. can be communicated.

The storage unit 120 may store grouping information acquired by the processor 140, information shared through inter-vehicle communication, etc.

The storage unit 120 has a flash memory type, a hard disk type, a micro type, and a card type (e.g., a Secure Digital Card (SD Card) or an eXtream Digital Card (XD Card). Memory such as RAM (Random Access Memory), SRAM (Static RAM), ROM (Read-Only Memory), PROM (Programmable ROM), EEPROM (Electrically Erasable PROM), and magnetic memory (MRAM) , Magnetic RAM, magnetic disk, and optical disk type memory.

The display unit 130 can display information about the own vehicle and grouped vehicles. At this time, the display unit 130 may display only the vehicle maker information of the vehicles grouped to protect personal information. The display unit 130 may be implemented as a head-up display (HUD), cluster, AVN (Audio Video Navigation), etc. Additionally, color input, etc. can be received directly from the user through the cluster's USM (User Setting Menu) menu. In addition, the display unit 130 includes a liquid crystal display (LCD), a thin film transistor liquid crystal display (TFT LCD), a light emitting diode (LED), and an organic light emitting diode (OLED, Organic LED). ), active OLED (AMOLED, Active Matrix OLED), flexible display, bent display, and 3D display.

FIG. 2 is a diagram for explaining a grouping process during driving of an autonomous driving control device according to an embodiment of the present invention, FIG. 3 is an example of matrix-type grouping according to an embodiment of the present invention, and FIG. 4 is a diagram illustrating This is an example diagram in which a plurality of groupings are created by the autonomous driving control device according to an embodiment of the present invention.

Referring to FIG. 2 , when displaying vehicles as blocks (rectangles), the autonomous driving control device 100 may group adjacent vehicles based on the own vehicle 101 in a matrix manner.

Referring to FIG. 3, the autonomous driving control device 100 is grouped in a 3*3 matrix method as in 301, a 3*5 matrix method as in 302, or a 5*5 matrix method as in 303. You can do this, and the size of the grouping can be changed as needed. At this time, examples such as those based on a 3*3 matrix are not limited to this, and the size of the matrix can be changed at any time.

Referring to FIG. 4, group 2 can be configured so that some of the vehicles in group 1 that have already been grouped overlap, and grouping can be performed so that some of the vehicles included in group 2 can configure group 3. In this way, multiple groups can be connected like a ring.

Additionally, the processor 140 may create a plurality of groups including the own vehicle when grouping the own vehicle with surrounding vehicles that have similar driving directions and destinations as the own vehicle while driving. The processor 140 can share vehicle driving information among the vehicles in the grouped group, and if there is a vehicle with a communication error among the vehicles in the grouped group, a fail safety mode is set to the vehicle with the communication error. ) can be requested to enter. At this time, fail-safety is a technology that allows safe driving by installing additional devices or systems in preparation for vehicle breakdowns and malfunctions. In self-driving vehicles, the proportion of electronic devices is high and the vehicle has to handle tasks on its own without a driver, making fail safety technology even more important.

When the processor 140 receives a request to enter the fail safety mode from another vehicle, the processor 140 may enter the fail safety mode and continue autonomous driving control based on vehicle driving information shared from the other vehicle.

Additionally, when the processor 140 detects a communication abnormality in the own vehicle, it can enter the own vehicle into a fail safety mode and continue autonomous driving control based on shared vehicle driving information of surrounding vehicles.

In this way, the processors 140 of grouped autonomous vehicles heading to the same destination share vehicle driving information such as driving speed, driving direction, and driving destination, and continuously update each other's driving information periodically. Accordingly, when a communication error occurs in one or more of the vehicles in the group, the processor 140 uses the shared vehicle driving information of other vehicles to control the autonomous driving to continue safely.

The processor 140 may create a new group including the first group and the second group among at least one group, and, according to a predetermined ratio, some of the vehicles included in the first group and those included in the second group. You can create a new group containing some of the vehicles you have purchased.

Figure 5 is an example of grouping at the time of shipment of an autonomous driving control device according to an embodiment of the present invention, Figure 6 is an example of regrouping a plurality of groups according to an embodiment of the present invention, and Figure 7 is an example of the grouping of an autonomous driving control device according to an embodiment of the present invention. This is a diagram to explain a method of regrouping a plurality of groups according to an embodiment of.

Referring to FIG. 5, the autonomous driving control device 100 can randomly group a plurality of vehicles being shipped. Figure 5 shows an example of performing a total of five groupings: group 1, group 2, group 3, group 4, and group 5.

Referring to FIG. 6, the autonomous driving control device 100 may connect the five groups grouped in FIG. 5 to create new groups 6, 7, and 8. That is, the autonomous driving control device 100 can configure group 6 by connecting group 1 and group 3, group 7 by connecting group 2 and group 4, and group 8 by connecting group 3 and group 5. there is. Accordingly, Group 6 and Group 8 are connected with Group 3 as a common denominator, and ultimately Group 1, Group 3, Group 5, Group 6, and Group 8 may include overlapping vehicles. In this way, the group is expanded by connecting multiple groups to create a new group, and through this expansion, the group that shares vehicle information can be expanded. In addition, vehicles being shipped store each other's information, so that if a problem such as vehicle information manipulation occurs in the future, it is possible to determine whether the vehicle information has been manipulated using the own vehicle information stored in another vehicle. Additionally, the autonomous driving control device 100 may periodically monitor communication signal values of grouped vehicles to determine whether hacking has occurred.

Referring to FIG. 7, 401 shows an example of creating 5 groups as shown in FIG. 5, and 402 is a method of creating group 6 by connecting group 1 and group 3 in the -1 manner, in which the 4 devices of group 1 An example of grouping a vehicle and one vehicle of group 3 is disclosed. In 403, an example of grouping three vehicles in group 1 and two vehicles in group 3 is disclosed when group 6 is created by connecting group 1 and group 3 in the -2 method. In this way, you can create an infinite number of groups by creating new groups using existing groups.

When the processor 140 designates a vehicle among a plurality of autonomous vehicles in one of at least one group as the main communication vehicle that communicates with the outside,

External communication data can be transmitted to surrounding vehicles grouped with the own vehicle. Additionally, the processor 140 can sequentially change and designate surrounding vehicles grouped with the host vehicle as the main communication vehicle according to a predetermined cycle.

In this way, grouping is performed at the time of vehicle shipment to prevent manipulation of vehicle information if another vehicle has vehicle information. At this time, to protect personal information, vehicle information may not be disclosed to each vehicle user, but only to the vehicle manufacturer.

Figure 8 is a diagram for explaining a variable method of vehicle communication between grouped vehicles according to another embodiment of the present invention. When the autonomous driving control device 100 communicates with the outside, there is a high possibility of being hacked by external communication. Accordingly, only one vehicle (101) among the grouped vehicles is allowed to communicate with the external transmitting device (201), and the vehicle that communicates with the outside transmits information from the outside to the remaining vehicles (102, 103, 104) in the group. The received information is transmitted, and the information transmitted by the remaining vehicles (102, 103, and 104) is transmitted to the outside. At this time, the vehicle that communicates with the outside can be randomly changed among the vehicles in the group according to a predetermined cycle. In other words, if one vehicle continues to communicate with the outside as the main vehicle, the possibility of that vehicle being hacked from the outside increases, so all vehicles in the group take turns becoming the main vehicle and communicating with the outside to minimize external hacking. can do.

In this way, the present invention can increase driving stability by preventing vehicle control errors caused by hacking, etc. by grouping vehicles and sharing vehicle information using a blockchain method, and can prevent manipulation of vehicle records in the event of an accident, thereby providing autonomy. By further strengthening the security of driving vehicles, marketability can be enhanced.

Hereinafter, a blockchain-based autonomous driving control method according to an embodiment of the present invention will be described in detail with reference to FIG. 9. Figure 9 is a flowchart for explaining a blockchain-based autonomous driving control method according to an embodiment of the present invention, and shows a method of performing grouping while driving and autonomous driving of grouped vehicles. Hereinafter, it is assumed that the autonomous driving control device 100 of FIG. 1 performs the process of FIG. 9. Additionally, in the description of FIG. 9, operations described as being performed by the autonomous driving control device 100 may be understood as being controlled by the processor 140 of the device 100.

Referring to FIG. 9, when the autonomous driving control device 100 starts the vehicle and starts driving (S101), it determines whether the vehicle is currently in autonomous driving mode (S102). If the vehicle is not currently in the autonomous driving mode, that is, in the normal driving mode, the autonomous driving control device 100 maintains the current driving mode (S103).

Meanwhile, if the vehicle is currently in autonomous driving mode, the autonomous driving control device 100 checks the driving direction and destination of the own vehicle (S104). At this time, the autonomous driving control device 100 can check the driving direction and destination of the own vehicle in conjunction with the navigation device 400.

Next, the autonomous driving control device 100 determines whether there are surrounding vehicles driving autonomously around the road on which the own vehicle is traveling (S105). At this time, the autonomous driving control device 100 may attempt to communicate with a surrounding vehicle and, if communication is successful, determine that a surrounding vehicle exists.

Accordingly, if there are no surrounding vehicles driving autonomously around the road on which the own vehicle is traveling, the current driving state is maintained (S106). On the other hand, when there are surrounding vehicles driving autonomously around the road on which the own vehicle is traveling, the autonomous driving control device 100 determines whether the driving direction and destination of the surrounding vehicles are similar to the driving direction and destination of the own vehicle (S107). That is, the autonomous driving control device 100 can compare the driving direction and destination of its own vehicle with the driving direction and destination of surrounding vehicles using driving information received from surrounding vehicles.

Accordingly, if the driving direction and destination of the surrounding vehicle are different from the driving direction and destination of the own vehicle, the autonomous driving control device 100 terminates without performing grouping. On the other hand, if the driving direction and destination of the surrounding vehicle are similar to the driving direction and destination of the own vehicle, the autonomous driving control device 100 groups the surrounding vehicle and the own vehicle (S108). At this time, grouping may be based on a matrix, as shown in FIGS. 2 to 4, but the shape and number of the matrix may change depending on the number of surrounding vehicles.

The autonomous driving control device 100 shares driving records with the vehicles in the grouped group (S109), periodically communicates with the grouped vehicles, and determines whether a communication error occurs (S110). At this time, communication abnormalities may include cases where data transmission and reception fail.

At this time, if a communication error occurs in one of the grouped vehicles, the autonomous driving control device 100 may request the vehicle in which the communication error occurred to enter the fail safety mode. Additionally, when determining that a communication error has occurred in the own vehicle or receiving a notification from a vehicle in the group that a communication error has occurred in the own vehicle, the autonomous driving control device 100 enters the own vehicle into the fail safety mode (S111).

Afterwards, the autonomous driving control device 100 of the vehicle that has entered the fail safety mode can continue to control autonomous driving using the driving records shared with surrounding vehicles (S112).

In this way, the present invention groups vehicles with similar driving directions and destinations by communicating with surrounding vehicles while the vehicle is driving, and shares driving information among the grouped vehicles, so that one of the grouped vehicles can be damaged by hacking, etc. Even if a communication error occurs, safe driving is possible by continuing autonomous driving based on previously shared vehicle driving information.

In addition, the present invention shares driving information between a plurality of grouped vehicles, so that even if one of the grouped vehicles has its vehicle information deleted by hacking, etc., the actual vehicle information can be recovered based on the shared driving information of other vehicles. You can.

Accordingly, the present invention manipulates the records of the vehicle when an accident occurs to disguise that the accident occurred due to a vehicle control error, or manipulates the records of the other vehicle to disguise the accident as the other party's mistake, but the vehicle driving information is already present in the grouped vehicle. is shared, so these operations can be easily identified.
