Route guidance method using fixed route running vehicle infomation

The present invention relates to a route guidance method using fixed route driving vehicle information. When guiding a route to a driver in a navigation system, the driver is confused by using fixed route driving vehicle information that travels on the same route as the route the driver will proceed. It relates to a route guidance method using fixed route driving vehicle information for generating guide information for easy junctions and providing them to a driver.

In general, a navigation system identifies a road network between an origin and destination and provides an optimal route for various moving objects including vehicles. To this end, the navigation system detects the driving position of the moving object by means of information transmitted by GPS (Global Positioning System) satellites and sensors such as a gyroscope and a speed sensor installed in the vehicle, and displays a map according to the detected current position. .

Through this, vehicle users can check the current location of the moving object and the shortest or optimal path from the current location to the destination using the navigation system, and plan the route the moving object will travel in advance according to the guidance of the navigation system,

By driving, the given road network can be used efficiently.

However, such a conventional navigation system allows the driver to easily recognize the turning point through an enlarged view of the bifurcation when the driver has to turn at the bifurcation, but the driver recognizes the turning point only by guiding the enlarged view of the bifurcation. There were limits to what could be done.

As a prior art for improving this, 'a HUD-based road guide providing apparatus and method' in Korean Patent Application Laid-Open No. 2015-0094382 has been proposed, which will be described with reference to FIG. 1 as follows.

The route generator generates a route to the destination (21), and thereafter, the controller displays a virtual preceding vehicle traveling along the route generated by the route generator, but the virtual preceding vehicle travels ahead of the own vehicle by a reference distance The augmented reality HUD (Head Up Display) is controlled to appear as if it were (22).

Thereafter, the augmented reality HUD displays a virtual preceding vehicle under the control of the controller (23), the controller adjusts the reference distance based on the speed of the own vehicle, and the controller adjusts the distance from the current position to the left/right turn point (hereinafter , the remaining distance) of the virtual preceding vehicle

By controlling the augmented reality HUD to display the blinking cycle of the lights differently, a virtual preceding vehicle is created on the augmented reality HUD, and then the virtual preceding vehicle is induced to a preset destination by linking with the location of the own vehicle, so that the driver By following the virtual preceding vehicle, it was designed to show the effect of making it easier to reach the destination.

However, this conventional technique has a disadvantage in that the sense of reality is lowered by generating a virtual preceding vehicle that is not related to the driving of the actual vehicle and following the vehicle to the driver.

The present invention devised in order to solve the problems of the prior art as described above has an object to provide route guidance that conforms to the actual driving environment by guiding the driver to follow a fixed-route driving vehicle that travels on an actual road.

2 is a basic configuration diagram for implementing a route guidance method using fixed route driving vehicle information according to the present invention. As shown in FIG. 2 , the present invention has a navigation 100 for guiding a route to a driver, and an image sensor module 150 and a remote server 200 integrated in the navigation 100 as a basic configuration.

Here, the navigation device 100 is a terminal that generally guides the optimal route, the shortest route, etc. from the starting point to the destination according to the destination set for the driver. In the present invention, the image sensor module 150 is essential.

In addition, the remote server 200 is a system in which information of a vehicle traveling on a fixed route is built into a database (DB), more preferably a Bus Information System (BIS), and the navigation 100 It serves to provide information of a vehicle traveling on a fixed route at the request of the navigation device 100 at the request of the navigation device 100 .

3 is a configuration diagram illustrating a detailed configuration of a navigation system according to the present invention. As shown in FIG. 3 , the detailed configuration of the navigation device 100 of the present invention is exemplified, and the map data DB 110 necessary for route guidance is provided, and the vehicle for generating guidance information to the user using the map data DB 110 is provided. It includes a location determination unit 140 for grasping current location information, and a control unit 120 that controls the overall configuration of the navigation device 100 .

In addition, a route search unit 160 that searches for a route according to the setting of the current location and destination of the vehicle and a guide information generator 130 that generates guide information for guiding a searched route to the driver according to the searched route are provided. and additionally, an image sensor module 150 for acquiring one or more second vehicles to be followed in order to generate guide information at a junction in the present invention.

4 is a flowchart for implementing the route guidance method using fixed route driving vehicle information according to the present invention. As shown in FIG. 4 , for the route guidance method using the fixed route driving vehicle information, first, the user transmits the current location and the driving route of the first vehicle being driven to the remote server ( S100 ), and the current of the first vehicle The location is acquired by a dead rocking (DR) system by GPS or a sensor system, and the driving route is the calculated optimal driving route to the destination set by the navigation system 100 .

The remote server 200 searches for a second vehicle that travels on one or more fixed routes matching the current location of the first vehicle and the calculated optimal driving route to the destination and provides the second vehicle as the first vehicle (S110).

Here, the second vehicle is a bus operating a regular route, and information collected about a vehicle operating a regular route by a Bus Information System (BIS) constructed and operated by most local governments is used. .

In addition, when the remote server 200 searches for the second vehicle, it is selected and provided based on the operation information database of the second vehicle built by the bus information system (BIS).

In general, this operation information database can utilize the information of the second vehicle collected to guide the arrival time of the bus at the bus stop, and based on this, information of the preceding vehicle and the following vehicle related to the current location of the first vehicle It is possible to obtain

Here, in the case of a preceding vehicle, it is information of a vehicle approaching a bus stop in a driving direction from a driving position of the first vehicle, and in the case of a following vehicle, it is information of a vehicle approaching the bus stop through which the first vehicle travels.

Here, in the general case, it is common to utilize the information of the preceding vehicle, but the following vehicle has a more stable operation of the bus, which is the second vehicle, compared to the operation of the first vehicle, and there is a possibility of overtaking the first vehicle. It is more preferable that the information of

As described above, from among the information on the second vehicle searched and provided by the remote server 200, an exception vehicle filtering is performed to distinguish a second vehicle suitable for route guidance and a second vehicle not suitable for route guidance (S120). In the case of a vehicle traveling in the exclusive bus lane, it is appropriate to exclude this exception vehicle filtering because it is inappropriate for the guidance of the first vehicle when following it because the driving method is different from the following target for driving guidance of the first vehicle. do.

Thereafter, a second vehicle with high guidance suitability for the first vehicle is selected from among one or more second vehicles transmitted from the remote server 200 ( S130 ), and when there is a second vehicle with high guidance suitability, fixed route driving The guidance is performed using a vehicle (S140), and when there is no second vehicle with high guidance suitability, the existing route guidance in the navigation device 100 of the first vehicle is used (S150).

Here, when a second vehicle with high guidance suitability exists, route guidance is performed by generating guidance information from the first vehicle so that the first vehicle follows the second vehicle.

In the case of such route guidance, in general, it is preferable that any one or more of the display corresponding to the function of the navigation device 100, the guidance by sound, and the head-up display is performed.

In addition, it is preferable that the guide information for the first vehicle is guide information about a junction, which in a normal case utilizes the guide information generated by the navigation 100 and clearly provides guidance on a point where the driver is easy to confuse. In order to do this, the guidance is made based on the guidance of the junction rather than the overall driving path of the first vehicle.

Here, the second vehicle that is selected and provided by the remote server 200 based on the driving information is the first vehicle located within the range of the radius from the current location where the first vehicle is driving to the junction where the guide information is to be generated. As information of the second vehicle is provided, it is limited to a case in which the traveling direction of the first vehicle and the traveling direction of the second vehicle coincide.

This means that the information of the second vehicle located within the range where the distance to the junction is the radius is not appropriate for performing route guidance of the first vehicle when the traveling direction of the first vehicle and the traveling direction of the second vehicle are opposite to each other. so excluded.

As such, it is necessary to select an optimal second vehicle to be utilized for route guidance of the first vehicle from among the second vehicles located within the range where the distance from the remote server 200 to the provided junction is the radius, which is the first vehicle. Select from among the second vehicles acquired by the image sensor module 150, which is generally a camera mounted on the first vehicle among the second vehicles, to facilitate recognition in the actual environment of the driving.

The operation of the image acquisition module is not a regular operation, but starts an operation a certain distance before the location of the junction that is easily confused by the driver of the first vehicle, and this distance is the same as setting a distance for guiding a specific point in conventional navigation. In the same way, let the user make a choice.

Here, when there are a plurality of second vehicles acquired by the image sensor module 150 , the selection of a target for the first vehicle to follow is determined by the second vehicle having the largest size among the images acquired by the image sensor module 150 . Selecting a vehicle is easier for the driver of the first vehicle to recognize because the following target is close to the assumption of the first vehicle.

In contrast, when the traveling speed of the first vehicle is different from that of the second vehicle among the second vehicles acquired by the image sensor module mounted on the first vehicle, the guide target junction is taken in consideration of the traveling speed of the second vehicle. It is also possible to select the second vehicle estimated to be located at the closest distance to the second vehicle having high guidance suitability.

Although it is common to select the second vehicle preceding the first vehicle as the following target, when the running speed of the second vehicle following is higher than that of the first vehicle, the turning point at which the following vehicle should be guided to the first vehicle rather than the preceding vehicle There is a case in which the second vehicle drives first, and in this case, a case in which the following second vehicle is more suitable for guidance is considered.

In this case, it is more preferable that the image sensor module 150 of the first vehicle has a function of photographing not only the front but also the rear.

Although the present invention has been illustrated and described with reference to preferred embodiments as described above, it is not limited to the above-described embodiments, and those of ordinary skill in the art to which the invention pertains within the scope not departing from the spirit of the present invention Various changes and modifications will be possible.
