VEHICULAR MASTER DEVICE, POWER SUPPLY MANAGEMENT METHOD FOR OBJECT FOR WHICH REWRITING IS NOT TO BE CARRIED OUT, AND POWER SUPPLY MANAGEMENT PROGRAM FOR OBJECT FOR WHICH REWRITING IS NOT TO BE CARRIED OUT

摘要

This vehicular master device (11) is equipped with: a rewriting specification data acquisition unit (74) for acquiring rewriting specification data from the outside; a rewriting specification data analysis unit (75) for analyzing the rewriting specification data acquired by the rewriting specification data acquisition unit; a rewriting target specification unit (81a) for specifying, on the basis of the analysis result from the rewriting specification data analysis unit, an electronic control device for which rewriting is to be carried out and an electronic control device for which rewriting is not to be carried out; an installation possibility determination unit (81b) for determining whether an installation is possible for an electronic control device for which rewriting is to be carried out; and a state transition control unit (81c) for carrying out control so as to place one or more electronic control devices for which rewriting is not to be carried out in a stopped state, a sleep state, or a power conservation operating state, when the installation possibility determination unit has determined that an installation is possible for an electronic control device for which rewriting is to be carried out.
