PROBLEM TO BE SOLVED: To provide a vehicle control device that can perform an open-valve operation for a relief valve while suppressing a variation in air-fuel ratio.SOLUTION: The vehicle control device includes: a low-pressure fuel pressure sensor 53a for detecting a pressure of fuel stored in a low-pressure delivery pipe 53; and a control device 100 for controlling a feed pump 512 based on a detection value of the low-pressure fuel pressure sensor 53a. The control device 100 performs the open-valve operation for the relief valve 515 when a state where a variation in power required for an engine 10 is within a predetermined range is continued for a predetermined period.SELECTED DRAWING: Figure 2 |
