To suppress the occurrence of a malfunction in an ECU in which supply and shutdown of the power is controlled by a relay control device.SOLUTION: A relay control device comprises a control unit which switches between a relay-on state of supplying the power to an ECU and a relay-off state of not supplying the power to the ECU for a plurality of relay circuits respectively connected to the plurality of ECUs. The plurality of ECUs comprises: a first ECU which has a transition function that makes the operation state of itself transition between at least two of the normal state, the sleep state and the power source-off state according to the power source state of the vehicle; and a second ECU which does not have the transition function. The control unit executes switching control of switching the second relay circuit connected to the second ECU in the plurality of relay circuits to the relay-off state while maintaining the first relay circuit connected to the first ECU in the plurality of relay circuits in the relay-on state following the change of the power source state.SELECTED DRAWING: Figure 1

    【課題】リレー制御装置により電力の供給及び遮断が制御されるECUにおける不具合の発生を抑制する。【解決手段】複数のECUにそれぞれ接続されている複数のリレー回路について、前記ECUへ電力を供給するリレーオン状態と、前記ECUへ電力を供給しないリレーオフ状態とにそれぞれ切り替える制御部を備え、複数の前記ECUは、前記車両の電源状態に応じて、自身の稼働状態を通常状態、スリープ状態及び電源オフ状態のうち少なくとも2つの間で遷移させる遷移機能を有する第1ECUと、前記遷移機能を有さない第2ECUと、を含み、前記制御部は、前記電源状態が変化することに伴い、複数の前記リレー回路のうち前記第1ECUに接続されている第1リレー回路を前記リレーオン状態に維持したまま、複数の前記リレー回路のうち前記第2ECUに接続されている第2リレー回路を前記リレーオフ状態に切り替える切替制御を実行する、リレー制御装置。【選択図】図1
