Hereinafter, the above-described contents will be described in detail through an embodiment according to the present invention.

As shown in FIG. 1, the GPS receiver 100 receives coordinate data and time data of the GPS satellites transmitted from the GPS satellites, outputs them to the microcomputer 600, and the key input unit 200 is a driver. Sets a route of a departure point and a destination, and outputs a route setting signal to the microcomputer 600.

In addition, the gyro sensor 300 detects a displacement angle in which the traveling direction of the vehicle changes and outputs the displacement angle data to the microcomputer 600, and the vehicle speed sensor 400 detects the vehicle speed and stores the vehicle speed data. Output to the microcomputer 600.

On the other hand, the DVD-RAM 500 capable of reading and writing a large amount of map data stores the map data and a driving history, which is a driving path that is used by the driver.

In addition, the microcomputer 600 extracts the current position of the vehicle through coordinate data and time data output from the GPS receiver 100, inputs a routing signal output from the key input unit 200, and then, The map data stored in the DVD-RAM 500 is read and a display control signal for displaying the driving route of the vehicle to the LCD is output to the LCD display panel 700.

On the other hand, the microcomputer 600 determines whether the road on which the vehicle is currently driving is a new road based on the displacement angle data output from the gyro sensor 300, and when the new road is a new road, the vehicle output from the vehicle speed sensor 400. The property of the new road is given through the speed data.

Then, when the attribution of the new road is completed, the microcomputer 600 stores the information on the new road from the path departure point to the point at which the current vehicle travels in the DVD-RAM 500.

In addition, the microcomputer 600 determines whether the current vehicle has arrived at the destination, and stores the driving history, which is the driving path of the vehicle when the vehicle arrives at the destination, in the DVD-RAM 500.

On the other hand, the LCD display panel 700 configures the present embodiment by displaying the driving path and the current position of the vehicle so that the user can see by the display control signal output from the microcomputer 600.

Hereinafter, an operation process of the experiential learning RGS route guidance apparatus in the vehicle navigation apparatus configured as described above will be described with reference to FIGS. 1 and 2.

First, the GPS receiver 100 receives coordinate data and time data of the GPS satellites transmitted from the GPS satellites and outputs the coordinate data to the microcomputer 600.

In addition, the gyro sensor 300 detects a displacement angle in which the traveling direction of the vehicle changes and outputs displacement angle data to the microcomputer 600.

Meanwhile, the vehicle speed sensor 400 detects the speed of the vehicle and outputs vehicle speed data to the microcomputer 600.

In addition, the DVD-RAM 500 capable of reading and writing a large amount of map data stores the map data and a driving history, which is a driving route used by the driver.

In this case, when the driver sets the route of the current vehicle's starting point and the destination to arrive through the key input unit 200, the key input unit 200 sends a path setting signal for the starting point and the destination of the vehicle to the microcomputer 600. Will print

On the other hand, the microcomputer 600 inputs a route setting signal for the starting point and destination of the vehicle output from the key input unit 200, and recognizes the starting point of the vehicle and the destination to arrive (S10).

In addition, the microcomputer 600 searches for driving history data, which is a driving route used by the driver stored in the DVD-RAM 500, and determines whether there is a starting and destination route set by the driver (S20).

On the other hand, the microcomputer 600 reads the map data stored in the DVD-RAM 500 when the driving history data corresponding to the starting and destination routes set by the driver are not present in the DVD-RAM 500. Then, the normal RGS route guidance to the destination is performed.

In addition, the LCD display panel 700 inputs a display control signal output from the microcomputer 600 to display a normal RGS path to a destination for the driver to see (S30).

However, when the driving history data corresponding to the starting and destination paths set by the driver are in the DVD-RAM 500, the microcomputer 600 reads the driving history data, which is a path that the driver prefers, and then the driving history. A display control signal for displaying map data is output to the LCD display panel 700.

Meanwhile, the LCD display panel 700 inputs a display control signal output from the microcomputer 600 to display driving history map data for the driver to view (S40).

In addition, the microcomputer 600 determines whether the vehicle is currently traveling through the RGS path through the displacement angle data output from the gyro sensor 300 (S50).

On the other hand, if the current vehicle is not driving through the RGS route, the microcomputer 600 determines whether the road on which the current vehicle travels is a road existing on the map data stored in the DVD-RAM 500 (S60). ).

In addition, the microcomputer 600 performs a new road registration operation when the road on which the vehicle currently runs is not a road existing on the map data stored in the DVD-RAM 500 (S70).

At this time, the new road registration performing step (S70) will be described as follows.

First, the microcomputer 600 inputs vehicle speed data output from the vehicle speed sensor 400 to measure and determine a current vehicle speed of the vehicle (S71).

Meanwhile, when the measured vehicle speed of the current vehicle is later than 60 km / h, for example, the microcomputer 600 assigns a new road as an attribute of a class such as a round-trip one lane or an unpaved road (S72), and then departs from the route departure point. Information on the new road to the point where the current vehicle has traveled is stored in the DVD-RAM 500 (S75).

In addition, when the measured vehicle speed of the current vehicle is faster than, for example, 80 km / h, the microcomputer 600 assigns the new road to the attribute of the same grade as the four-lane round trip (S73), and then the current vehicle starts from the path departure point. Information on the new road to the point where the vehicle has traveled is stored in the DVD-RAM 500 (S75).

And, if the measured vehicle speed of the current vehicle is, for example, 60km / h or more and later than 80km / h, the microcomputer 600 grants the new road to the attribute of the same grade as the two-way lane (S74), the path Information about the new road from the departure point to the point at which the current vehicle travels is stored in the DVD-RAM 500 (S75).

In this case, the reference speed that the microcomputer 600 sets to give an attribute according to the grade of the new road will be arbitrarily set, and the reference speed can be changed according to the operator's selection.

On the other hand, the microcomputer 600 determines whether the vehicle has arrived at the destination (S80), and when the vehicle arrives at the destination, the driving history data, which is the current driving route of the vehicle, is stored in the DVD-RAM 500. (S90).

As described above, the experience-learning RGS route guidance apparatus and control method thereof in the present invention have a DVD-RAM equipped with a function of reading and writing a large amount of map data, and the DVD-RAM. By saving your favorite driving route, you can not only guide the driver's favorite RGS route, but also store information about the new road on DVD-RAM when the vehicle is driving on a new road. In addition, there is an effect that can guide the driver to a better optimal RGS route even if the vehicle is driving on a newly established road or driving on an extended road.
