摘要： An electronic control device includes a substrate, a plurality of component-mounted wires, a plurality of electronic components, a common wire, an interrupt wire and a protective layer. The component-mounted wires and the common wire are disposed on the substrate. The electronic components are mounted on the respective component-mounted wires and are coupled with the common wire. The interrupt wire is coupled between one component-mounted wire and the common wire, and is configured to melt in accordance with heat generated by an overcurrent to interrupt a coupling between the component-mounted wire and the common wire. The protective layer covers a surface of the substrate including the interrupt wire and defines an opening portion so that at least a portion of the interrupt wire is exposed.

摘要： An electrical control unit includes a constant voltage supply unit which supplies a constant voltage to a fuel injector, a boosted voltage supply unit which supplies a boosted voltage to the fuel injector, a control unit which controls supply timings of the constant voltage supply unit and the boosted voltage supply unit, and an interrupter which interrupts electric current when a short-circuit occurs in the boosted voltage supply unit. When an interruption of the interrupter is not detected, the boosted voltage supply unit supplies boosted voltage to start a fuel injection and the constant voltage supply unit supplies constant voltage to continue the fuel injection. When an interruption of the interrupter is detected, the constant voltage supply unit and the boosted voltage supply unit advance an interrupted power supply start timing relative to a non-interrupted power supply start timing to prevent delay of a fuel injection start timing.
