Abstract
Control for the flexible distribution of update software is realized.An in-vehicle software distribution system 1 is configured comprising an in-vehicle software distribution server (telematics center 10) which manages updates to an identical function by means of a campaign for an in-vehicle system (an engine ECU 241, for example) of a plurality of vehicles 20 and distributes software of the campaign remotely to target vehicles, a terminal 30, and a software update apparatus 210 which is mounted in each of the plurality of vehicles 20. Furthermore, in the telematics center 10, a campaign management unit 112 categorizes the campaign target vehicles into groups based on a predetermined criterion and creates a plurality of sub-campaigns which are subordinate to the campaign for each of the categorized groups, and a software distribution unit (an update software distribution unit 113) distributes software remotely to the target vehicles for each of the sub-campaigns.
