  • Patent number: 10634085
    Abstract: A control device for an fuel pump includes an electronic control unit. The fuel pump is an electric fuel pump configured to supply fuel to a fuel pipe to which a fuel injection valve disposed within a cylinder of an engine is coupled. The electronic control unit executes an inter-injection discharge control of executing fuel discharge from the fuel pump at a predetermined timing between an Nth fuel injection and an (N+1)th fuel injection from the fuel injection valve. The electronic control unit changes a discharge ratio in accordance with an operational state of the internal combustion engine during the execution of the inter-injection discharge control. The discharge ratio is a ratio of the number of times of fuel discharge from the high-pressure fuel pump to the number of times of fuel injection from the fuel injection valve.
