A vehicular electronic control system (1) is provided with: a vehicular master device (11); a vehicle power source determining unit (92a) which determines if a vehicle power source is on or off; a rewriting determining unit (92b) which determines whether a program is being rewritten; a first power source self-holding determining unit (92c) which, if it is determined that the vehicle power source is off and it is determined that a program is being rewritten, determines that self-holding of the power source by a vehicular slave device is required; and a power source self-holding instructing unit(92d) which, if it is determined that self-holding of the power source is required, instructs the vehicular slave device to enable a first power source self-holding circuit. The vehicular slave device enables the first power source self-holding circuit if instructed to enable the first power source self-holding circuit by the vehicular master device.
在车辆用电子控制系统(1)中,车辆用主装置(11)具备:车辆电源判定部(92a),判定车辆电源的接通断开;改写中判定部(92b),判定是否是程序改写中;第一电源自保持判定部(92c),在判定为车辆电源断开且判定为是程序改写中的情况下,判定在车辆用从装置中将电源自保持的必要性;以及电源自保持指示部(92d),在判定为需要将电源自保持的情况下,对车辆用从装置指示使第一电源自保持电路有效化。车辆用从装置在从车辆用主装置指示了使第一电源自保持电路有效化的情况下,使第一电源自保持电路有效化。
