Patent number: 10161342Abstract: A control device for a high-pressure pump includes: a determination unit, an acquisition unit, and an electric power setting unit. The determination unit determines whether a movable portion of an electromagnetic valve has been moved to a closed position to close the electromagnetic valve when the electromagnetic valve is energized. The acquisition unit acquires, as an electromagnetic-valve response time, a period of time from a start of the energization of the electromagnetic valve until when it is determined that the electromagnetic valve has been closed. The electric power setting unit sets a supply power to the electromagnetic valve by repeating a process in which the supply power to the electromagnetic valve is reduced so as to be smaller than a previous value until the electromagnetic-valve response time reaches a predefined upper limit value.Type: GrantFiled: April 4, 2016Date of Patent: December 25, 2018Assignee: DENSO CORPORATIONInventors: Takahisa Natori, Tomoyuki Takagawa, Hiroshi Yamaguchi, Yasuo Hirata
