The relay control device is mounted in a vehicle and includes a control unit that switches, for each of a plurality of relay circuits connected to each of a plurality of ECUs, between a relay-on state in which power is supplied to the ECUs and a relay-off state in which power is not supplied to the ECUs, the plurality of ECUs including: a first ECU; a transition function for transitioning the operation state of the vehicle between at least two of a normal state, a dormant state, and a power-off state in accordance with the power state of the vehicle; and a second ECU that does not have the transition function, the control unit performing a switching control of switching the second ECU from the relay-on state to the relay-off state in accordance with a change in the power supply state, and switching the second ECU from the relay-on state to the relay-off state in accordance with a change in the power supply state. A first relay circuit connected to the first ECU among the plurality of relay circuits is maintained in the relay ON state, and a second relay circuit connected to the second ECU among the plurality of relay circuits is switched to the relay OFF state.
继电器控制装置搭载于车辆,具备控制部,该控制部对于与多个ECU分别连接的多个继电器电路分别在向所述ECU供给电力的继电器接通状态与不向所述ECU供给电力的继电器断开状态之间切换,多个所述ECU包括:第一ECU,具有根据所述车辆的电源状态而使自身的运转状态在通常状态、休眠状态及电源断开状态中的至少两个状态之间转变的转变功能;及第二ECU,不具有所述转变功能,所述控制部执行如下切换控制:当随着所述电源状态变化而要将所述第二ECU从所述继电器接通状态切换为所述继电器断开状态时,将多个所述继电器电路中的与所述第一ECU连接的第一继电器电路维持为所述继电器接通状态的状态下,将多个所述继电器电路中的与所述第二ECU连接的第二继电器电路切换为所述继电器断开状态。
