PROBLEM TO BE SOLVED: To improve effective fuel consumption of a vehicle during idle stop.SOLUTION: A control device stops drive of a fuel pump during idle stop of an internal combustion engine, estimates a fuel pressure decreasing according to an elapsed time after stopping the fuel pump, and operates output of the fuel pump so as to recover until the necessary size with which the fuel pressure is restarted within a delay time from a time of a restarting request, on the basis of the estimation value of the fuel pressure at the time when restarting of the internal combustion engine is required. |
