FUEL INJECTION CONTROL DEVICE

Provided is a fuel injection control device capable of detecting individual differences in fuel injection valves and appropriately collecting information on the individual differences. For this reason, the fuel injection control device includes a fuel injection valve drive circuit that supplies a current or a voltage to a coil of a fuel injection valve to drive the fuel injection valve, a valve body operation time period detection unit that detects a valve body operation time period related to an operation of a valve body of the fuel injection valve, and a state determination unit that determines that at least one of the fuel injection valve, the valve body operation time period detection unit, and the fuel injection valve drive circuit is abnormal based on information related to a valve body operation time period detected by the valve body operation time period detection unit.
