BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to a driving lane information providing apparatus and a method thereof, and more particularly, to an apparatus and method for providing a lane departure driving situation to a vehicle in real time.

Generally, vehicle navigation has a GPS receiving device and map data, and performs a function of guiding a route to a destination according to a route setting of a user. The vehicle navigation is generally mounted or installed in the vehicle, displays the position of the vehicle on the map on the map, and guides the traveling direction of the vehicle while moving on the map. Conventional navigation has provided a route by recognizing a road as a single lane, without considering the driving situation by car.

Such conventional navigation has an advantage in fast route search, but it does not reflect the driving situation according to the traffic lane, so the driver must directly determine the driving situation and drive the lane when traveling on the highway.

However, since the forward visibility of the driver is limited, the lane can not be determined in consideration of the overall road driving situation, so that it is difficult for the driver to select the optimum lane that smoothly flows the traffic flow.

In order to solve the problems of the prior art described above, it is an object of the present invention to provide, to a driver in real time, recommended driving lane information and traffic situation information for driving traffic optimization using traffic information of a vehicle and driving lane information do.

The objects of the present invention are not limited to the above-mentioned objects, and other objects not mentioned can be clearly understood by those skilled in the art from the following description.

As described above, according to the present invention, the map data is updated to reflect the real-time differentiated driving situation, and the navigation of each vehicle is provided with the secondary driving situation information and / or the recommended lane information, There is an advantage of reducing the congestion and shortening the running time.

In addition, the present invention provides an advantage of increasing the driving efficiency by allowing the driver to determine the lane in advance by providing the driver with not only the information of the current driving section but also the information of the driving situation information of the next driving section.

For example, when the terminal mounted on the vehicle 100 is a location signal source for transmitting signals and data to the driving lane information providing device 200, the data collecting unit 210 collects the coordinate data of the location signal source.

The map data management unit 220 obtains the distribution of the location signal source coordinates included in the same segment (map segment i) of the road on the map data from the coordinate data of the signal sources collected in real time and the distance information between the coordinates.

Specifically, the map data management unit 220 stores the number of signal sources (vehicles) included in the coordinate range (x coordinate range) of the predetermined road, the distance data between the signal source coordinates, or the average value of the distance data Can be obtained.

The map data management unit 220 can generate the density data of the lane for each map segment by comparing the sizes of the above-described signal source coordinates, the distance data between the coordinates, and the average value of the distance data.

In step S30, the recommended driving lane information calculated by the determination unit 230 may be a lane for reaching the destination set by the driver at the minimum driving time.

Fig. 5B shows an embodiment in which the traffic information for each traffic lane is shown using colors. For example, a red one-lane car has a relatively large number of vehicles compared to other lanes, and a green four-lane car has a relatively small number of cars.

In step S40, the transmission unit 240 transmits the recommended driving lane information and the lane departure driving situation information to the vehicle.

The driving lane providing apparatus 200 according to the embodiment of the present invention performs the driver assist function by recommending a driving lane that not only transmits the driving situation information to the navigation of each vehicle in real time but also allows the driver to arrive at the destination in the shortest time .
