FUEL INJECTION CONTROLLER

A fuel injection control device is provided with a plurality of pressure sensors 44 and 45 that individually detect pressures of fuel in a common rail 25 and an electronic control unit (ECU) 46. When respective detected values of two fuel pressure sensors 44 and 45 are in a normally-possible range and when the deviation of the two detected values is smaller than a given determination value, the ECU 46 sets the higher detected value as the fuel pressure. The ECU 46 obtains an injection period based upon a fuel injection amount that is set in accordance with an operating state of an engine 11 and the fuel pressure, and controls fuel injection valves 23 so as to inject the fuel during the injection period.
