Hereinafter, a method of guiding a driving route of the vehicle 1 using the driving route guidance system 100 shown in FIG. 1 will be described with reference to FIG. 3 . Hereinafter, each step indicated by S1 to S9 may be performed with the vehicle 1 as a main body.

First, a destination and order details are input from the driver (step S1). In step S1 , the destination and the order information may be input to the input unit 10 of the vehicle 1 .

Next, store information within a threshold distance on the driving route of the vehicle 1 according to the order content is searched for based on the current location of the vehicle 1 and the input destination (step S2 ). In step S2 , the store information search may be performed through the store search unit 22 of the route calculating unit 20 .

If the number of stores to be searched is less than a predetermined number in step S2, the threshold distance is increased by a predetermined size and then the search is performed again (step S21).

When the number of stores searched for according to the re-search in step S21 is equal to or greater than a certain number, the next step S3 may be performed.

After searching for store information within a critical distance on the driving route of the vehicle 1, the preparation time of the order content for each store according to the order content and the searched store information is transmitted (step S3).

In step S3 , the route calculating unit 20 of the vehicle 1 transmits the order contents and the searched store information to the OEM server unit 30 , and the preparation time Ta of the order contents for each store from the OEM server unit 30 . , Tb and Tc) can be transmitted.

In addition, the OEM server unit 30 may transmit the order contents and the searched store information to the store server unit 40 , and may receive the preparation time of the order contents for each store from the store server unit 40 .

After step S3, a route through each store and a required time required for passing through each store are transmitted according to the destination and the searched store information (step S4).

In step S4 , the route calculating unit 20 of the vehicle 1 transmits the destination and the searched store information to the navigation server unit 50 , and the route from the navigation server unit 50 through each store and each You can receive the time required for passing through the store.

The navigation server unit 50 may calculate the required time required for passing through each store as in Equation 1 above and transmit it to the route calculation unit 20 of the vehicle 1 .

After receiving the preparation time of the order contents for each store and the time required for passing through each store, the optimal route is calculated according to the preparation time for the order contents for each store and the time required for passing through each store ( step S5).

In step S5 , the path calculating unit 20 of the vehicle 1 may calculate the optimal path as in Equation 2 above.

After the calculation of the optimal path is completed, the calculated optimal path is displayed on the display unit 60 (step S6).

On the other hand, there may be a case in which another driving path is selected instead of selecting the optimal path calculated through the path calculating unit 20 according to the will of the driver.

Therefore, in order to determine whether the driver does not select the calculated optimal route, it is checked whether the calculated optimal route is used after the step S6 (step S7).

When the driver uses the calculated optimal route in step S7, the driving route of the vehicle 1 is guided according to the calculated optimal route (step S71).

If the driver does not use the optimal route calculated in step S7, a driving route other than the calculated optimal route is displayed on the display unit 60 (step S72).

In step S7 , whether the driver uses the calculated optimal route may be determined based on route selection information input through the input unit 10 .

After the step S72, it is checked whether any one of the displayed other driving routes is selected (step S8).

In this case, when the driver does not select any one of the driving paths other than the calculated optimal path in step S8, step S1 may be performed again.

Meanwhile, when any one of the other driving paths is selected in step S8, the driving path of the vehicle 1 is guided according to the selected driving path (step S9).

According to the present invention, since the optimal route is calculated according to the preparation time of the order contents for each store and the required time when passing through each store, the vehicle 1 quickly and quickly passes through the store even when the driver passes through the store. Then you can drive to your destination.

In addition, according to the present invention, the service or goods required by the driver can be provided more efficiently.
