  "textContent": "[Problem to be Solved] To provide a driving control device for a fuel pump that can properly control the fuel pump such that an operation state is maintained with a simple configuration without requiring a storage capacity for storing a 3D map and a high processing ability for map calculation. [Solution] A driving control device for a fuel pump is characterized by including a valve-opening-rate calculating unit that calculates an injector valve opening rate, which is an injection time of an injector per unit time and a driving control unit that sets a voltage duty ratio of a driving voltage that should be applied to the fuel pump that supplies fuel in a fuel tank to a fuel pipe communicating with the injector, in which the driving control unit sets, as a voltage duty ratio of the driving voltage that should be applied to the fuel pump, a value proportional to the injector valve opening rate calculated by the valve-opening-rate calculating unit.",
