<P>PROBLEM TO BE SOLVED: To provide a method and a device for efficiently controlling a high-pressure fuel supply pump including a normal time opening type solenoid-actuated intake valve by lower noise without depending on especially timing of deceleration pulse, strict calculation of amplitude and exact adjustment so much. <P>SOLUTION: The method and the device for controlling the high-pressure fuel supply pump is configured to supply pressurized fuel to an internal combustion engine by including a step in which control current is applied to the solenoid-actuated intake valve 120 during first periods ΔT0 and ΔT1, the intake valve 120 is moved up to a second stop position in a second direction and the intake valve 120 is maintained at the second stop position by magnetic force, and a step in which control current is applied to the solenoid-actuated intake valve 120 during moving of the solenoid-actuated intake valve 120 in a first direction from the second stop position for a second period ΔT2 after the first periods ΔT0 and ΔT1. <P>COPYRIGHT: (C)2012,JPO&INPIT |
