Control device for high-pressure pump

A control device for a high-pressure pump, the control device adjusting a fuel discharge amount of the high-pressure pump by opening or closing a control valve through energization control, and comprising:

• a control amount change part that changes an energization control amount of the control valve;
• an operation detection part that detects an operating condition of the control valve when the energization control amount is changed;
• a learning part that learns the energization control amount based on the operating condition of the control valve to reduce an operating noise of the high-pressure pump;
• and
• a determination part that determines whether or not an operating time of the control valve for the energization control amount is shorter than a time that allows for the detection of the operating condition of the control valve, wherein the learning part prohibits the learning when the operating time of the control valve for the energization control amount is determined to be shorter than the time that allows for the detection of the operating condition of the control valve.
