The invention provides a vehicular master device, an update data verification method, and an update data verification program. This vehicular master device (11) comprises a first device (13) equippedwith: an update data acquisition unit (72) for acquiring update data from a center device (3); an update data distribution unit (73) for distributing the update data acquired by the update data acquisition unit to a ECU (19) for which rewriting is to be carried out; a process execution request unit (79b) for requesting that a second device (12) execute at least a portion of a process involved in verification of the update data, before the update data distribution unit distributes the update data; a process result acquisition unit (79c) for acquiring a process result from the second device; anda verification unit (79d) for using the process result acquired by the process result acquisition unit to verify the update data.
本发明提供车辆用主装置、更新数据的验证方法以及更新数据的验证程序。在车辆用主装置(11)中,第一装置(13)具备:更新数据获取部(72),从中心装置(3)获取更新数据;更新数据分发部(73),将通过更新数据获取部获取到的更新数据分发至改写对象ECU(19);处理执行请求部(79b),在更新数据分发部分发更新数据前,对第二装置(12)请求执行与更新数据的验证相关联的处理中的至少一部分处理;处理结果获取部(79c),从第二装置获取处理结果;以及验证部(79d),使用通过处理结果获取部获取的处理结果来验证更新数据。
