A method of providing driving simulation based on V2X communication, and a method of providing driving guide and advertisement contents using it

The present invention relates to a method for providing a driving simulation based on V2X communication, and a method for providing a driving guide and advertisement content using the same. More specifically, the present invention provides a driving guide for the safe driving of a driver by allowing the user to experience driving that is almost similar to the real road environment in which he/she wants to experience driving a car according to the actual driving environment and driving scenario on a virtual map. On the other hand, it relates to a method of exposing customized advertisement contents among advertisement information collected from advertisers to users who enjoy driving practice or driving games on a virtual map.

Vehicles have been developed from the development of mechanical devices to the combination of electronic devices as a means of providing people with rapid spatial mobility. Electronic devices mounted on vehicles were initially used for vehicle control, but are gradually providing telematics, multimedia services, and Internet services, and are ultimately developing into autonomous vehicle technology for intelligent vehicles.

Along with the development of such vehicles, intelligent transport system (ITS) technology linked to roads is being developed, and recently, cooperative ITS technology in which vehicles and road infrastructure are fused is being actively researched.

Meanwhile, the V2X (Vehicle to Everything) vehicle safety system is a technology that provides safety services to all vehicles driving in an ITS environment through V2V (Vehicle to Vehicle) or V2I (Vehicle to Infrastructure)-based cooperative communication. Verification and evaluation through experiments are required.

However, in general, verification and evaluation of systems and services in real road environments requires a lot of time and money. That is, testing through actual driving requires a lot of cost, time, and labor loss, and it is difficult to repeatedly test the same scenario, and there is a risk that human accidents may occur. In addition, repeated tests are required in situations requiring the same results depending on the situation, but this is not possible in the actual driving test.

In order to perform effective integrated verification and evaluation, a method for solving the above problems and limitations is required, and an integrated simulation system capable of providing many advantages as an alternative to this is required.

In particular, in the case of driving simulation using a virtual map, it is possible to experience various events that may occur on a specific real road based on the real road environment, and through this, experience to prevent accidents in advance can be accumulated. In addition, by providing various events that are difficult to experience in real life beyond learning through the above driving simulation according to systematic scenarios, driving can be provided as content that can be enjoyed like a game.

The WAVE communication standard uses a dedicated frequency band of 5.9GHz and is composed of IEEE 802.11p and IEEE 1609.x standards.

Here, IEEE 802.11p includes a physical layer and a MAC layer for wireless transmission, and IEEE 1609.x includes an upper multi-channel layer, a networking layer, an authentication security layer, and an application service layer mounted on IEEE 802.11p.

WAVE communication has a maximum data transfer rate of 27Mbps in a 200km/h high-speed moving environment, and a radio wave coverage of up to 1km and 100msec.

It aims at short packet latency, short radio link access and PER = 0.1 communication performance.

In addition, the RF frequency band has a radio technology standard so that the ITS system does not receive radio wave interference by using the ITS dedicated frequency band rather than the ISM band concept.

In addition, in consideration of the use of public services, the radio wave output can be increased up to 44.8 dBm (about 30 Watt), and the channel bandwidth is changed from the 20 MHz band to the 10 MHz band by doubling the symbol time of the transmitted signal to improve the propagation delay spread and It was made to have more robust characteristics in timing.

Here, the software on the kernel includes a device driver, MAC transmission/reception function, routing function, IP packet function, WSMP safety message function, management function, authentication and security protocol function, etc., and application service software includes vehicle safety service, cooperative autonomous driving service and a driver interface, and the like.
