The invention discloses a central device, a specification data generation method, and program for generating specification data. An ECU reprogramming data database 204 of a central device 3 stores data of an update program for an ECU 19, amongst a plurality of ECUs 19 installed in a vehicle, of which an application program is to be updated. A configuration information database 208 stores, along with the vehicle type, an "ECU ID" corresponding to each ECU 19 and vehicle-related information such as an "ECU SW ID" for each application program stored in the ECU 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 the basis 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 the data includes 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.
本发明公开中心装置、规格数据的生成方法以及规格数据生成用程序,在中心装置(3)的ECU重编程数据DB(204)存储有搭载于车辆的多个ECU(19)中成为更新应用程序的对象的ECU(19)的更新程序的数据。在结构信息DB(208)存储有对多个ECU(19)各自的“ECU ID”以及存储于ECU(19)的应用程序的“ECU SW ID”等车辆相关信息和车辆的种类。在ECU元数据DB(205)存储有改写对象ECU(19)的属性以及与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。
