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.

First claim

What is claimed is:

1. A method for notifying of a necessity for hydrogen charging through position monitoring of a hydrogen station, the method comprising:
receiving, by a controller, information regarding a surrounding charging station;
determining, by the controller, a nearest charging station on a route toward a destination among charging stations except a charging station incapable of performing charging;
calculating, by the 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 on a display device a warning by the controller of the necessity for hydrogen charging when the expected travel distance exceeds the remaining travel distance,
wherein the received information of the charging station includes information retarding a charging capability and information regarding a differential pressure charging capability.

2. The method of claim 1 , 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.

3. 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.

4. 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:
receive information regarding a surround charging station;
determine a nearest charging station on a route toward a destination among charging stations except a charging station incapable of performing charging;
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 on a display device a warning of the necessity for hydrogen charging when the expected travel distance exceeds the remaining travel distance,
wherein the received information of the charging station includes information regarding a charging capability and information regarding a differential pressure charging capability.

5. The system of claim 4 , 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.

6. A non-transitory computer readable medium containing program instructions executed by a controller, the computer readable medium comprising:
program instructions that receive information regarding a surrounding charging station;
program instructions that determine a nearest charging station on a route toward a destination among charging stations except a charging station incapable of performing charging;
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 on a display device a warning by the controller of the necessity for hydrogen charging when the expected travel distance exceeds the remaining travel distance,
wherein the received information of the charging station includes information regarding a charging capability and information regarding a differential pressure charging capability.
