2 is a conceptual diagram illustrating an operation of a server according to an embodiment, and FIG. 3 is a conceptual diagram illustrating an operation of a vehicle according to an embodiment.

A traffic server can form an infrastructure that continuously collects and reflects traffic information, such as V2I and C-ITS.

The traffic server can collect autonomous driving-related data by composing a system consisting of a central server and a local device with multi-channel cameras and communication functions in a place similar to a crossroad with a complex road shape.

Meanwhile, the service server can calculate autonomous driving parameters suitable for regional characteristics and provide them to the vehicle in real time.

The traffic server can select a driving area in which the vehicle travels, and provide a system at the corresponding point similar to the camera for collecting traffic information currently installed on each road to collect data.

Meanwhile, the service server primarily identifies the vehicle model and the type of the installed autonomous driving system through real-time communication with each autonomous vehicle, and determines whether the current system is active or manual operation, etc. can be collected

Even if the traffic server is not an autonomous vehicle, it can identify the vehicle type through the camera to determine the vehicle between Lv0~2, collect driving pattern data, and perform statistical collection of traffic conditions. Meanwhile, the driving pattern data may be included in the traffic situation information in which the traffic server is formed.

The service server may generate the autonomous driving-related data parameter set based on the traffic law information and the traffic condition information of the driving area formed by the traffic server by the above-described method.

The service server may also transmit this parameter set to the vehicle. Drivers can receive this set of data parameters when entering a driving area to modify the autonomous driving parameters of their existing vehicles.

The traffic server can collect information on autonomous and non/semi-autonomous vehicles based on cameras and sensors provided in the driving area, and can collect statistical data by sending traffic situation information to the service server, and perform analysis can do.

The traffic server continuously collects and processes data from devices at the driving area using wireless communication, and short-term statistical data can be continuously derived through analysis.

The traffic server can derive long-term statistical data such as the number of past accidents or accident types in the driving area from the database of each country.

Meanwhile, the service server may calculate regional/national driving characteristic data by performing these steps for the traffic law information of the driving area of the traffic server and the traffic condition information of the driving area.

In addition, the service server may receive information of the vehicle driving in the driving area, and may form first and second parameters capable of modifying the driving parameters of the vehicle by comparing the information of the vehicle with the information provided by the traffic server.

Specifically, the first parameter may be generated by comparing vehicle information and the traffic law information.

In addition, the second parameter may be formed by comparing the vehicle information and the traffic condition information of the driving area.

Meanwhile, the traffic situation information includes the regular traffic situation, and includes driving characteristics of local drivers in the driving area and information on the traffic order guide.

The characteristics of the local driver may also include information on national characteristics and driving habits of the corresponding driving area.

Meanwhile, the service server may provide the first parameter and the second parameter formed by the above-described operation to the vehicle.

In addition, the vehicle may receive the first parameter and the second parameter and use it to modify the autonomous driving parameters of the existing vehicle. A detailed operation related thereto will be described later.

In addition, the service server may continuously perform feedback of such long-term statistical data.

The service server may apply a unique weight that meets the environmental regulations for each country/city to the first parameter and the second parameter to provide it to the vehicle.

The service server may request transmission of the vehicle's unique weight by linking GPS information and legal information of the driving area in which the vehicle is traveling.

On the other hand, when the vehicle receives parameters from the service server, the sign recognition technology can be changed for each driving country.

The service server may apply a unique factor in consideration of the driving characteristics of local drivers. For example, when the vehicle drives in the Busan area and in the Seoul area in Korea, the unique factor may be transmitted differently.

Meanwhile, the service server can provide the vehicle with control logic that varies parameters even between countries that drive on the right and on the left. Referring to FIG. 3, the vehicle basically performs real-time operation through sensor data and camera data as before. can be done

In the vehicle, a separate logic may analyze the accumulated statistical data inside to determine the vehicle driving pattern.

Specifically, the vehicle may perform autonomous driving based on autonomous driving parameters.

The vehicle may receive the first parameter and the second parameter from the service server. Meanwhile, the vehicle may modify autonomous driving parameters based on the parameters received by the user from the service server.

The vehicle may proceed with vehicle operation based on the modified autonomous driving parameters. In addition, the vehicle may provide feedback to the service server based on driver's feedback and data matching with actual traffic conditions.

Meanwhile, the operations described with reference to FIGS. 2 and 3 are merely exemplary for explaining the operation of the present invention, and there is no limitation on the parameters provided by the server and the operation of the vehicle using the parameters.

4 and 5 are diagrams for explaining a driving situation of a vehicle according to an exemplary embodiment.

Referring to FIGS. 4 and 5 , the vehicle V4-300 requires a different driving pattern because the driving conditions in the city or the surrounding area, or in a region with low traffic volume or traffic congestion, are different even within the same country.

When the width of the road on which the vehicle V4-300 is traveling changes, when the curvature changes greatly or when the downhill is severe, or when classified as an accident-prone area, a system parameter for driving control is required differently from the existing ones.

Accordingly, in such a case, the traffic server and the service server may form a parameter set by continuously collecting traffic law information and traffic situation information of a corresponding area.

In this specification, a corresponding parameter set is defined as a first parameter and a second parameter.

Meanwhile, referring to FIG. 5 , each country (N1, N2) has different legislation on autonomous driving, and even in neighboring countries, national characteristics and driving habits are often very different, so self-driving system parameters that reflect this are also needed. In the present invention, the vehicle may use the second parameter reflecting national characteristics and driving habits.

The service server may manage the first parameter and the second parameter as a parameter set, and the data based thereon may be continuously collected and processed through the above-described system and reflected through continuous analysis and feedback.

On the other hand, the vehicle V5-300 may also receive from the server the driving direction of a different vehicle for each country (N1, N2), sign information, and first and second parameters to which traffic laws and regulations are applied, from the server even in this case, based on this Autonomous driving may be performed by changing autonomous driving parameters of an autonomous driving vehicle that is already in operation.

Also, the service server may generate a second parameter based on the traffic situation information ( 1004 ).

The service server may transmit the first parameter and the second parameter to the vehicle ( 1005 ).

Meanwhile, if the driver of the vehicle agrees to receive the first parameter and the second parameter ( 1006 ), the vehicle may receive the first parameter and the second parameter to change the current autonomous driving parameter of the vehicle ( 1007 ).

The computer-readable recording medium includes any type of recording medium in which instructions readable by the computer are stored. For example, there may be a read only memory (ROM), a random access memory (RAM), a magnetic tape, a magnetic disk, a flash memory, an optical data storage device, and the like.
