This vehicular electronic control system (1) comprises a vehicular master device (11) that acquires, from an electronic control device for which rewriting is to be carried out and in which a nonvolatile memory having a plurality of data storage sides is installed, data storage side information that includes information with which it is possible to identify which side is an operation side and information with which it is possible to identify software versions of the operation side and a non-operation side, and sends the acquired data storage side information to a center device. On the basis ofthe operation side and software versions identified by the data storage side information received from the vehicular master device, the center device (3) selects update data applicable to the non-operation side, and transmits a distribution package containing the selected update data to the vehicular master device.
在车辆用电子控制系统(1)中,车辆用主装置(11)从搭载有在多个面具有数据储存面的非易失性存储器的改写对象的电子控制装置获取数据储存面信息,并将获取到的数据储存面信息发送至中心装置,上述数据储存面信息包括能够确定哪个面是运用面的信息和能够确定运用面以及非运用面的软件版本的信息。中心装置(3)基于根据从车辆用主装置接收到的该数据储存面信息确定的软件版本以及运用面,选定适合非运用面的更新数据,并将包括选定的该更新数据的分发数据包发送至车辆用主装置。
