Abstract
A high-pressure pump control device is applied to an internal combustion engine including a high-pressure pump supplied with fuel discharged from a low-pressure pump and an injector supplied with fuel discharged from the high-pressure pump. The high-pressure pump control device includes a prediction unit predicting whether a discharge quantity of the high-pressure pump exceeds a discharge quantity of the low-pressure pump and a restricting unit executing a discharge quantity restriction control to restrict a discharge quantity of the high-pressure pump not to exceed a predetermined value when the prediction unit predicts that a discharge quantity of the high-pressure pump exceeds a discharge quantity of the low-pressure pump.
