In addition, the terms described below are terms defined in consideration of functions in the present invention, and may vary depending on the intention or custom of the user or operator. Therefore, definitions of these terms should be made based on the content throughout this specification.

Figure 1 is an example diagram for explaining a system in which a route guidance service method is performed according to an embodiment of the present invention, and Figures 2 to 4 are flow charts for explaining a route guidance service method according to an embodiment of the present invention. With reference to this, the route guidance service method according to this embodiment will be described as follows.

The navigation system 100 includes a control unit, a display unit, an input unit, a location information receiver, a communication unit, and a map DB to provide route guidance.

For example, the display unit may include a display device and display route guidance.

The input unit may receive input from the user. For example, the input unit can receive input of a destination or waypoint from the user, and can also be configured to receive control commands for the navigation device.

This input unit may be configured in the form of a touch screen, and in this case, the input unit and the display unit may be integrated. However, the present invention is not limited to this method, and various types of input units may be possible. For example, the input unit may be composed of an input device such as a touch pad or microphone.

The location information receiver can receive information about the location of the navigation device. In other words, the location information receiver allows the current location of the navigation device to be determined using a satellite navigation system such as GPS.

The communication unit may perform communication of the server 110. For example, the communication unit may communicate with the server 110 using a mobile communication network, etc. However, the communication method of the Ministry of Communications is not limited to this.

Map DB stores map data. For example, the map DB may store road links, properties of each link, node list of intersections for each link, coordinates of each node, etc. as map data, and the control unit uses this map data to perform route navigation. It can be done.

Alternatively, the control unit may be configured to receive the searched route from the server 110 through the communication unit and guide the route.

However, the navigation 100 according to the present invention is not limited to the above-described configuration, and performing route guidance using the above-described location information in a navigation device corresponds to a technology widely known in the technical field to which the present invention pertains. Therefore, a detailed description of this will be omitted.

The server 110 can provide a route guidance service in conjunction with the navigation 100, and a detailed description of the operation of the server 110 will be described later.

As can be seen in FIG. 2, the navigation 100 and the server 110 may first perform a process of identifying the user's driving pattern.

Specifically, when a route departure occurs (S200), the navigation system 100 transmits route departure information to the server 110 (S210). That is, if a route deviation occurs while the vehicle is in operation, the navigation system 100 transmits information related to the route deviation to the server 110, allowing the server 110 to analyze the pattern of branch points where the user is vulnerable.

At this time, the route deviation information transmitted by the navigation system 100 may include user identification information, departure point information, and route information.

That is, in this embodiment, analyzing the user's driving pattern is performed for each user, so when transmitting route deviation information, the navigation system 100 can also transmit user identification information that allows the user to be identified.

In addition, this route deviation information includes information on the point of departure and route information related to the departure, including the intersection where the departure occurred and what type of route deviation (for example, the normal route was a left turn, but the type of route deviation occurred due to driving straight). So that you can find out if it was there.

Next, the server 110 analyzes the route departure information and calculates the user's driving vulnerability pattern (S220). For example, the server 110 may pattern vulnerable driving patterns by dividing them into road types at intersections and escape route types.

Specifically, there may be a plurality of road types. For example, type 1 may be an intersection with a left turn only lane, and type 2 may be an intersection with a turn junction.

Deviation path types can also be classified in the same way. For example, there may be a type where the normal path was a left turn, but a deviation from the path occurred due to driving straight.

In addition, the server 110 may analyze the user's driving vulnerability pattern by further considering the degree of congestion at the intersection, and the degree of congestion may be divided into high, medium, and low.

In other words, the server 110 can analyze the route departure information to determine the type in which the user is likely to deviate from the route. For example, should a left turn route be driven at an intersection where there is a left turn only lane? Cases where users are unable to enter the left turn lane due to heavy road congestion and deviate from the route can be analyzed as a type of user likely to deviate from the route.

Meanwhile, in the present invention, an intersection is a concept that includes not only intersections of three or more intersections, but also junctions of overpasses or underpasses, and highway interchanges.

After the above step (S220), the server 110 converts the analyzed pattern into a database (S230). That is, the server 110 stores the driving vulnerability pattern calculated in step S220 so that it can be used for later route guidance.

Next, as shown in FIG. 3, the navigation system 100 and the server 110 may perform a process of identifying an expected departure point and providing information about it when providing route guidance.

Specifically, when a route search is requested from the navigation 100 (S300), the server 110 performs a route search to the destination (S310).

At this time, the navigation 100 may transmit a request including user identification information and destination information to the server 110. That is, as described above, since patterned guidance information is provided for each user in this embodiment, the navigation system 100 can transmit a route search request including user identification information to the server 110.

Afterwards, the server 110 performs a route search to the transmitted destination and, for example, may determine the route based on the shortest distance or minimum time. However, since the server 110 performing this path search is a widely known technology in the technical field to which the present invention belongs, a detailed description thereof will be omitted.

Next, the server 110 determines the expected departure point within the path searched in step S310 (S320). That is, the server 110 can identify a point where the user is likely to deviate from the route, that is, an expected departure point, within the route to the destination, based on the above-described driving vulnerability pattern.

Specifically, the server 110 may identify the expected departure point by comparing the road type of the intersection within the route to the destination and the path type at the intersection with the driving vulnerability pattern described above.

For example, if a left turn must be performed at an intersection (intersection road type) where there is a left turn only lane (escape route type) and the user's driving pattern is vulnerable, the server 110 allows the user to make a left turn within the route to the destination. If there is a point where a left turn must be made at an intersection with only available lanes, that point can be identified as the expected departure point.

Therefore, there may be multiple expected departure points, and the user's driving vulnerability pattern may also be multiple.

After the step (S330), the server 110 transmits information about the route discovered in the step (S310) and the expected departure point identified in the step (S320) to the navigation device 100 (S330). At this time, the information about the expected departure point may include not only location information of the expected departure point, but also detailed guidance information about the point.

For example, such detailed guidance information may be provided 1km before the point: “The lanes where left turns are possible are lanes 1 and 2. Please move lanes in advance.”, “Traffic congestion is heavy before entering the intersection.” It may be information that provides guidance, etc.

The navigation system 100, which has received information about the expected departure point, can reduce the possibility of the vehicle deviating from the route by providing detailed guidance along with route guidance. This will be described in more detail with reference to FIG. 4 as follows.

The navigation system 100 first provides route guidance to the destination (S400). That is, the navigation 100 can provide route guidance using a route discovered by itself or a route transmitted from the server 110.

Next, the navigation 110 determines whether the expected departure point has been reached (S410). At this time, reaching the expected departure point may mean being located at a point where the remaining distance to the expected departure point is less than a certain distance.

As a result of the determination in the above step (S410), if the expected departure point has been reached, the navigation 100 provides detailed guidance on the point (S420). In other words, the navigation system (100) 1km before the expected departure point says, “The lanes where left turns are possible are lanes 1 and 2. Please move lanes in advance.”, “Traffic congestion is heavy before entering the intersection.” By providing detailed guidance, etc., you can prevent users from leaving the route.

Meanwhile, as a result of the determination in step S410, if the expected departure point has not been reached and the destination has not been reached (S430), the navigation system 100 returns to step S400 and continues to provide route guidance.

As such, the route guidance service method according to an embodiment of the present invention calculates the user's driving vulnerability pattern, uses this to identify the expected departure point within the route, and provides detailed guidance for the point, thereby determining the possibility of the vehicle deviating from the route. so that it can be reduced.

The present invention has been described with reference to the embodiments shown in the drawings, but these are merely exemplary, and those skilled in the art will recognize that various modifications and other equivalent embodiments are possible therefrom. You will understand. Therefore, the scope of technical protection of the present invention should be determined by the scope of the patent claims below.
