<P>PROBLEM TO BE SOLVED: To maintain a feed pressure of a low pressure pump at low pressure. <P>SOLUTION: A control apparatus (100) controls a fuel supply system (300) including: a feed pump (330) for supplying low pressure fuel; a high pressure pump (350) for supplying high pressure fuel obtained by the low pressure fuel being pressurized; a first injection device (342) for jetting the low pressure fuel to an intake port (209) of an internal combustion engine (200); and a second injection device (362) for jetting the high pressure fuel into a cylinder of the internal combustion engine. The control apparatus includes: a feed pressure control device for controlling the feed pressure to be at the minimum feed pressure which is the minimum value in a range where a fuel pressure of the high pressure fuel does not become an outlier, when at least the second injection device is used; and an injection-period correction device for making an injection period of the first injection device longer than the time when minimum-feed-pressure control is not performed, when the minimum-feed-pressure control is performed in a period of combination use of the first and second injection devices. <P>COPYRIGHT: (C)2013,JPO&INPIT |
