Description

A system and method for provisioning of driving path information, and a mobile terminal for generating of driving path guide message having a vehicle driving route information providing system, a vehicle driving route information providing method, and a guidance message generating function.

The present invention relates to a vehicle driving route information providing apparatus, and more particularly, to a vehicle driving route information providing apparatus that receives a request for providing route information from a mobile terminal, based on a starting route and a destination information selected by a subscriber. Each guide point and a guide code corresponding to the guide message are generated and transmitted to the mobile terminal. When the guide point and the guide code are received, the mobile terminal outputs a guide message according to the corresponding guide code. The present invention relates to a vehicle driving route information providing system.

Recently, traffic congestion has become a big social issue due to the increase of automobiles and the complexity of traffic environment. This traffic congestion not only wastes driver's time but also wastes unnecessary energy. Moreover, in the case of freight vehicles, the timely delivery of goods, but there is a problem that the logistics costs increase due to traffic jams.

In addition, in the case of a driver, there are various driving routes in order to reach a destination, and it is necessary to select an optimum route according to the traffic information in such a driving route to drive a vehicle. By doing so, the driver can reduce unnecessary effort due to driving and can reduce fatigue.

Recently, in order to provide convenience to the driver while solving the above problems, a vehicle navigation system has been widely used. The vehicle navigation system detects the position of the vehicle by using a location tracking device attached to the vehicle, and provides the driver with information on the driving route by using map information and traffic information. One such conventional technique is Korean Patent Application No. 10-2001-0045851. The conventional vehicle navigation apparatus as described above will be briefly described with reference to the drawings.

1 is a view showing a schematic configuration of a vehicle navigation system according to a conventional embodiment.

As shown in the figure, a conventional navigation system is composed of a service platform for providing a service and a mobile terminal for requesting a service connected to the service platform via a wireless network. First, in order to use the service, the subscriber accesses the service platform through the mobile terminal and then requests a route guidance service (S10). In this case, the service platform receiving a service request from the mobile terminal receives information about a source and a destination from the mobile terminal.

Then, the service platform extracts the entire route data based on the source and destination information input by the subscriber through the mobile terminal and generates information on each node of the route data (S20). As such, when the generation of the information on each node is completed, the service platform transmits the generated node information to the mobile terminal requesting the service (S30).

FIG. 2 is a diagram illustrating an example of a structure of data (path guide data) transmitted from a service platform to a mobile terminal according to the conventional embodiment shown in FIG. 1.

As shown in the figure, the route guide data is divided into an entire route information section and a node information section. The node information unit is divided by the number of each node constituting the whole.

In this case, the full path information unit includes a general data field for the total data size, the total number of path nodes, the total path length, and the entire path. Each node information is composed of header information, coordinate information, interpolation point data coordinates (1 to n), link guidance information, driving information, intersection name, and road number field. The link guidance information is composed of an entry link angle, an exit link angle, and an adjacent link angle field, and the driving information is composed of a distance to an end point and a distance to a next node.

FIG. 3 is a diagram illustrating an example of a process of processing and displaying route guide information in a mobile terminal according to the conventional embodiment illustrated in FIG. 1.

As shown in the figure, it is assumed that the current position of the vehicle is A, and moves in the vehicle's movement induction direction B via the node # 1. At this time, the information of the node # 1 received by the mobile terminal is composed of a coordinate, entry link angle, entry link angle, adjacent link angle, distance to the end point, distance to the next node, intersection name, road number field.

First, the mobile terminal detects the position of the vehicle by a global positioning system (GPS) and calculates a distance from the vehicle based on the coordinate information of the node # 1 included in the node # 1 information (S41). At this time, the mobile terminal calculates the distance between the node # 1 and the vehicle, for example, 100m.

Subsequently, the mobile terminal generates a guide code based on an entry link angle, an exit link angle, and an adjacent link angle included in the node # 1 information. For example, if the entry link angle is -80 ° and the exit link angle is 45 °, the mobile terminal determines that the vehicle's movement induction direction B is right with respect to the current position A of the vehicle, and corresponds to "right turn". Generate a guide code (S42).

As described above, when the distance between the node # 1 and the vehicle is calculated and a guide code is generated, the mobile terminal combines the distance and the guide code and outputs a voice message "It is a right turn in front of 100 meters" (S44). The mobile terminal calculates the remaining distance to the destination based on the distance to the end point included in the node # 1 information and the distance between the current vehicle and the node # 1, calculates the required time, and displays it on the display (S45). . Accordingly, the driver can drive the vehicle by referring to the voice message and the information displayed on the display.

However, the conventional method of generating the guide code with reference to the link guidance information included in the node information has a problem that the path guidance data transmitted from the service platform to the mobile terminal becomes large. That is, in the related art, since the mobile terminal extracts a guide message previously stored in the mobile terminal by referring to the entry link angle and the exit link angle among the route guidance data received from the service platform, the route guidance transmitted from the service platform to the mobile terminal. The size of the data increases, and the size of the route guide data increases as the distance between the starting point and the destination input by the subscriber increases, so that the field for storing information about each node increases. Furthermore, as the number of adjacent roads connected to each node in the path increases, the number of fields representing angles increases proportionally. Therefore, according to the conventional method as described above, there is a problem that the data transmitted through the wireless network becomes large, and the transmitted data occupies a large amount of memory of the mobile terminal.

In addition, as described above, the conventional mobile terminal has a problem in that process resources of the mobile terminal are excessively occupied because each node must perform a guide code generation process to output a guide message.

Accordingly, the present invention has been proposed to solve the above-mentioned problems, and sets in advance a guide point to generate a guide message on a path selected by the subscriber, and generates a guide code to be generated at the set guide point in advance. An object of the present invention is to provide a vehicle driving route information providing system that can be transmitted to a terminal.

The present invention also provides a mobile terminal capable of receiving a guide point and a guide code from the vehicle driving route information providing system, and generating a guide message according to a corresponding guide code when the guide point and the guide code correspond to a location included in the received guide point. There is a purpose.
