Title:
A control device of a high-pressure pump
Document Type and Number:
Japanese Patent JP6341176
Kind Code:
B2
Abstract:
A control device includes a control amount change part that changes an energization control amount of a 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 a 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. 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.
