Abstract

A method is provided for notifying a driver that charging is required determined by utilizing the calculated remaining travel distance of the vehicle, the position information of the charging station and the position information about the destination. In particular, the method determines when the total travel distance in consideration of the destination exceeds the remaining travel distance of the vehicle. The driver is notified of the necessity for charging during the initial traveling, and before traveling beyond the rechargeable returning distance.

Claims

1. A method for notifying of a necessity for hydrogen charging through position monitoring of a hydrogen station, the method comprising:

calculating, by a controller, an expected travel distance from input destination information and calculating a remaining travel distance of a current vehicle from information regarding the currently remaining hydrogen fuel;

comparing, by the controller, the calculated expected travel distance to the remaining travel distance of the vehicle; and

outputting a warning by the controller of the necessity for hydrogen charging when the expected travel distance exceeds the remaining travel distance.

2. The method of claim 1, further comprising:

receiving, by the controller, information regarding a surrounding charging station,

prior to calculating the expected travel distance and the remaining travel distance.

3. The method of claim 2, further comprising:

determining, by the controller, a nearest charging station on a route from the received information of the charging station to the destination.

4. The method of claim 2, wherein the received information of the charging station includes information regarding a charging capability and information regarding a differential pressure charging capability.

5. The method of claim 4, further comprising:

determining, by the controller, the nearest charging station on the route to the destination among the charging stations except the charging station incapable of performing charging.

6. The method of claim 3, wherein the expected travel distance is determined as a value by summing a destination arrival distance required to reach the destination and a charging station returning distance required to arrive at a charging station determined to be nearest.

7. The method of claim 1, further comprising:

calculating, by the controller, the remaining travel distance of the vehicle during traveling in real time;

comparing, by the controller, the remaining travel distance calculated in real time to the charging station returning distance required to arrive at the nearest charging station from the current position; and

outputting, by a controller, warning necessity of the hydrogen charging when the charging station returning distance detected in real time exceeds the remaining travel distance calculated in real time.

8. The method of claim 5, wherein the expected travel distance is determined as a value by summing a destination arrival distance required to reach the destination and a charging station returning distance required to arrive a charging station determined to be nearest.

9. A system for notifying of a necessity for hydrogen charging through position monitoring of a hydrogen station, the system comprising:

a memory configured to store program instructions; and

a processor configured to execute the program instructions, the program instructions when executed are configured to;

calculate an expected travel distance from input destination information and calculating a remaining travel distance of a current vehicle from information regarding the currently remaining hydrogen fuel;

compare the calculated expected travel distance to the remaining travel distance of the vehicle; and

output a warning of the necessity for hydrogen charging when the expected travel distance exceeds the remaining travel distance.

10. The system of claim 9, wherein the processor receives information regarding a surrounding charging station, prior to calculating the expected travel distance and the remaining travel distance.

11. The system of claim 9, wherein the processor determines a nearest charging station on a route from the received information of the charging station to the destination.

12. The system of claim 9, wherein the processor receives information of the charging station includes information regarding a charging capability and information regarding a differential pressure charging capability.

13. The system of claim 9, wherein the processor determines, the nearest charging station on the route to the destination among the charging stations except the charging station incapable of performing charging.

14. The system of claim 9, wherein the processor determines the expected travel distance as a value by summing a destination arrival distance required to reach the destination and a charging station returning distance required to arrive at a charging station determined to be nearest.

15. A non-transitory computer readable medium containing program instructions executed by a controller, the computer readable medium comprising:

program instructions that notify of a necessity for hydrogen charging through position monitoring of a hydrogen station;

program instructions that calculate an expected travel distance from input destination information and calculate a remaining travel distance of a current vehicle from information regarding the currently remaining hydrogen fuel;

program instructions that compare the calculated expected travel distance to the remaining travel distance of the vehicle; and

program instructions that output a warning by the controller of the necessity for hydrogen charging when the expected travel distance exceeds the remaining travel distance.
