Program update system, method, and program

Abstract

To provide a program update system capable of reducing the number of man-hours required for each vehicle.SOLUTION: A program update system includes: a vehicle including a plurality of in-vehicle apparatuses; and a server provided outside the vehicle. Each in-vehicle apparatus has: a storage unit that stores one or more programs; an in-vehicle apparatus side communication unit that communicates with the server; and an update execution unit that updates the programs stored in the storage unit based on communication with the server by the in-vehicle apparatus side communication unit. The server includes: a server side communication unit that communicates with each in-vehicle apparatus; a first transmission unit that transmits information indicating that the update of the programs is possible based on information received from each in-vehicle apparatus through communication by the server side communication unit to an external device that is not fixedly provided in the vehicle; and a second transmission unit that executes update processing in which, when an instruction to execute the update processing of the programs is received from the external device, update data of the programs is transmitted to the vehicle without going through the external device based on the instruction received from the external device.SELECTED DRAWING: Figure 1

Claims
