Route suggestion device and method therefor

1. A route suggestion device, comprising:

at least one processor; and

an audio, video, navigation (AVN) device,

wherein the at least one processor is configured to:

determine whether it is possible for a vehicle to arrive at a destination based on a current drivable distance of the vehicle;

search for at least one charging station along a route to the destination by using a driving scheduling function to schedule a final route to the destination if it is determined that it is impossible for the vehicle to arrive at the destination without being charged;

determine a first charging station chosen from among the at least one charging station as a suitable waypoint based on an item of interest of a passenger of the vehicle, the item of interest reflecting a will of the passenger;

generate an optimal route to the destination including the first charging station;

direct the AVN device to display a final schedule where the vehicle passes through the first charging station,

monitor at least one charger of the first charging station, while the vehicle is traveling, and

continue directing the AVN device to display the final schedule, if it is determined that there is a charger available at the first charging station,

wherein the final schedule where the vehicle passes through the first charging station includes: a final route including the first charging station, a shortest distance to the destination, and a charging time at the first charging station.

2. The route suggestion device of claim 1 , wherein the at least one processor is further configured to monitor a charger of the first charging station to identify whether it is possible to use the charger of the first charging station in real time.

3. The route suggestion device of claim 1 , wherein the item of interest of the passenger is identified by a user input of the passenger, and

wherein the at least one processor is further configured to search for a place associated with the item of interest of the passenger, in response to the user input, and determine the first charging station as the waypoint, based on the found result.

4. The route suggestion device of claim 1 , wherein the item of interest of the passenger includes an item for a place where the passenger is able to utilize a timeframe when the vehicle is being charged at the first charging station.

5. The route suggestion device of claim 1 ,

wherein the at least one processor is further configured to display the item of interest of the passenger in the form of a pop-up notification by the AVN device.

6. The route suggestion device of claim 1 , wherein the at least one processor is further configured to:

monitor at least one charger of the first charging station, while the vehicle is traveling, and

search for a charging station capable of charging the vehicle along the route to the destination again, if it is determined that there is no charger available at the first charging station.

7. The route suggestion device of claim 6 , wherein the at least one processor is further configured to automatically change the waypoint to a second charging station chosen from among the charging stations found again along the route to the destination, based on the item of interest of the passenger.

8. The route suggestion device of claim 7 ,

wherein the at least one processor is configured to direct the AVN device to display the final schedule where the vehicle passes through the second charging station, after the waypoint is automatically changed to the second charging station, and

wherein the final schedule where the vehicle passes through the second charging station includes a final route including the second charging station, a shortest distance to the destination, and a charging time at the second charging station.

9. The route suggestion device of claim 1 , wherein the at least one processor is further configured to determine the first charging station as the waypoint with regard to a charging time from among the at least one charging station, after searching for the at least one charging station.

10. A route suggestion method, comprising:

determining whether it is possible for a vehicle to arrive at a destination based on a current drivable distance of the vehicle;

searching for at least one charging station along a route to the destination, using a driving scheduling function of scheduling a final route to the destination determining that it is impossible for the vehicle to arrive at the destination without being charged;

determining a first charging station chosen from among the at least one charging station as a suitable waypoint based on an item of interest of a passenger of the vehicle, the item of interest reflecting a will of the passenger;

generating an optimal route to the destination including the first charging station;

displaying a final schedule where the vehicle passes through the first charging station by an audio, video, navigation (AVN) device;

monitoring at least one charger of the first charging station, while the vehicle is traveling, and

continuously displaying the final schedule by the AVN device, if it is determined that there is a charger available at the first charging station,

wherein the final schedule where the vehicle passes through the first charging station includes a final route including the first charging station, a shortest distance to the destination, and a charging time at the first charging station.

11. The route suggestion method of claim 10 , further comprising:

monitoring a charger of the first charging station to identify whether the charger of the first charging station is available in real time.

12. The route suggestion method of claim 10 , wherein the item of interest of the passenger is identified by a user input of the passenger, and

wherein the determining of the first charging station as the waypoint step further includes:

searching for a place associated with the item of interest of the passenger, in response to the user input; and

determining the first charging station as the waypoint, based on the found result.

13. The route suggestion method of claim 10 , wherein the item of interest of the passenger includes an item for a place where the passenger is able to utilize a timeframe when the vehicle is being charged at the first charging station.

14. The route suggestion method of claim 10 , further comprising:

displaying the item of interest of the passenger in the form of a pop-up notification on the AVN device.

15. The route suggestion method of claim 10 , further comprising:

monitoring the at least one charger of the first charging station, while the vehicle is traveling, and

searching for a charging station capable of charging the vehicle along the route to the destination again, if it is determined that there is no charger available at the first charging station.

16. The route suggestion method of claim 15 , further comprising:

automatically changing the waypoint to a second charging station chosen from among charging stations found again along the route to the destination, based on the item of interest of the passenger.

17. The route suggestion method of claim 16 , further comprising:

displaying a final schedule where the vehicle passes through the second charging station by the AVN device, after the waypoint is automatically changed to the second charging station, and

wherein the final schedule where the vehicle passes through the second charging station includes a final route including the second charging station, a shortest distance to the destination, and a charging time at the second charging station.

18. The route suggestion method of claim 10 , further comprising:

determining the first charging station as the waypoint with regard to a charging time from among the at least one charging station, after searching for the at least one charging station.
