OPERATION SUPPORT DEVICE, OPERATION SUPPORT SYSTEM, AND OPERATION SUPPORT METHOD OF VEHICLE

摘要

PROBLEM TO BE SOLVED: To provide information to a user, the information for causing the user to intuitively recognize to what extent a vehicle can go somewhere on the way before returning to a return position such as a user's home without replenishing energy for traveling.SOLUTION: An operation support device 10 acquires a surplus travel distance in which a vehicle can further travel after securing the amount of energy to return to a return position 305 from the current position 300. The operation support device 10 then acquires a reciprocating travel possible area 315 in which the vehicle can go somewhere on the way to the return position on the basis of the surplus travel distance, and displays in a graphic the reciprocating travel possible area 315 on a display device 31 together with the current position 300, the return position 305, and a returning path 310.
