ABSTRACT:
The engine ECU executes a program including the step of setting an upper limit guard value of a fuel pressure by executing low fuel pressure control in the case where a low fuel pressure control execution condition is satisfied with fulfillment of conditions that execution of the low fuel pressure control is permitted, that engine speed NE is lower than a threshold value, and that the atmospheric pressure is higher than a threshold value, and the step of controlling the fuel pressure to be a target fuel pressure within a range not exceeding the upper limit guard value.
