VEHICLE PROGRAM REWRITING SYSTEM, VEHICLE MASTER DEVICE, METHOD FOR CONTROLLING SYNCHRONIZATION OF PROGRESS STATE, AND PROGRAM FOR CONTROLLING SYNCHRONIZATION OF PROGRESS STATE

摘要

PROBLEM TO BE SOLVED: To appropriately synchronize the progress states of rewriting of a program in a plurality of display terminals.;SOLUTION: In a vehicle program rewriting system 1, a vehicle master device 11 comprises: a first progress state determination unit 88a that determines a first progress state related to rewriting of a program; a first progress state transmission unit 88b that transmits the first progress state determined by the first progress state determination unit to a center device; a second progress state acquisition unit 88c that acquires a second progress state related to the rewriting of the program from the center device; and a first display instruction unit 88d that, on the basis of the first progress state determined by the first progress state determination unit and a second progress state acquired by the second progress state acquisition unit, instructs creation of a content that can be displayed on a display terminal mounted on a vehicle.;SELECTED DRAWING: Figure 175;COPYRIGHT: (C)2020,JPO&INPIT
