Title: IN-VEHICLE UPDATE SYSTEM, IN-VEHICLE UPDATE DEVICE, AND METHOD FOR UPDATING COMMUNICATION DEVICE
Abstract:
Provided are an in-vehicle update system, an in-vehicle update device, and a method for updating a communication device, with which a process for updating of a communication device mounted in a vehicle can be performed without reducing convenience related to a user's use of the vehicle. The in-vehicle update device has: a travel information acquisition unit that acquires vehicle travel information; a travel information transmission unit that transmits the acquired information to a server device; an update information acquisition unit that acquires an update program for a communication device of the vehicle from the server device, which is outside of the vehicle; and an update information transmission unit that transmits the acquired update program to the communication device. The in-vehicle update device updates a program stored in a storage unit in the communication device. The server device has: a travel information reception unit that receives the travel information transmitted by the in-vehicle update device; an update timing determination unit that determines the timing for performing an update process on the communication device by means of the in-vehicle update device, on the basis of the received information; and a start instruction transmission unit that transmits a start instruction for the update process to the in-vehicle update device, on the basis of the determined update timing.
