PROBLEM TO BE SOLVED: To provide an electronic control device which can suppress physical enlargement while performing the control of an automatic transmission and the control of an automatic start and an automatic restart of an engine.SOLUTION: An ECU is connected with a plurality of solenoid valves for controlling an automatic transmission of a vehicle, an oil pump motor for supplying oil to the automatic transmission which is connected to a plurality of the solenoid valves in series thereto, and a relay which is connected to a plurality of the solenoid valves in series thereto, and connected to the oil pump motor in parallel therewith. A control microcomputer of the ECU determines whether or not an ISS condition for automatically stopping an engine of the vehicle is established (S10). Then, when the ISS condition is established, the control microcomputer turns on the solenoid valves, turns on the oil pump motor by drive currents of the solenoid valves by turning off the relay, and supplies oil to the automatic transmission (S11, S12).SELECTED DRAWING: Figure 2
【課題】自動変速機の制御と、エンジンの自動停止と自動再始動の制御とを行いつつ、体格の大型化を抑制できる電子制御装置を提供すること。【解決手段】ECUは、車両の自動変速機を制御するための複数のソレノイドバルブと、複数のソレノイドバルブと直列に接続され自動変速機にオイルを供給するためのオイルポンプモータと、複数のソレノイドバルブと直列で且つオイルポンプモータと並列に接続されたリレーとが接続されている。ECUの制御マイコンは、車両のエンジンを自動的に停止させるISS条件が成立したか否かを判定する(S10)。そして、制御マイコンは、ISS条件が成立した場合に、ソレノイドバルブをオンにするとともに、リレーをオフにすることでソレノイドバルブの駆動電流によりオイルポンプモータをオンにして、自動変速機にオイルを供給する(S11、S12)。【選択図】図2
