An ECU reprogramming data database 204 stores data of an update program for an ECU 19 which is installed in a vehicle and of which an application program is to be updated. A configuration informationdatabase 208 stores, along with the vehicle type, vehicle-related information such as the ECU ID for each of a plurality of ECUs 19 and the ECU SW ID of the application programs stored on the ECUs 19.An ECU metadata database 205 stores update data-related information pertaining to update data and attributes of the ECU 19 to be rewritten. A specification data generation unit 201 generates, on thebasis of the information stored in the configuration information database 208 and the ECU metadata database 205, specification data to be transmitted to the vehicle together with update data to be written to the target ECU 19, such that information pertaining to the type, attributes and update data for the target ECU 19, and information indicating the rewrite environment pertaining to the data update are included. A package generation unit 202 generates a distribution package including the specification data and the reprogramming data.

    本发明提供中心装置、分发包的生成方法以及分发包生成用程序,在ECU重编数据DB(204)存储有搭载于车辆且成为应用程序的更新对象的ECU(19)的更新程序的数据。在结构信息DB(208)与车辆的种类一起存储有多个ECU(19)各自的“ECU ID”以及存储于ECU(19)的应用程序的“ECU SW ID”等车辆相关信息。在ECU元数据DB(205)存储有改写对象ECU(19)的属性以及更新数据相关的更新数据相关信息。规格数据生成部(201)基于结构信息DB(208)以及ECU元数据DB(205)所存储的信息,将与写入到对象ECU(19)的更新数据一起发送到车辆的规格数据生成为包含对象ECU(19)的种类、属性、更新数据相关信息、以及表示与数据更新相关的改写环境的信息。包生成部(202)生成包含规格数据和重编数据的分发包。
