PROBLEM TO BE SOLVED: To properly perform in-traveling eco-run control without causing the deterioration of the drivability of a driver accompanied by a change of a power generation voltage of an alternator, and without causing a restart failure of an engine, related to a power generation voltage control device for a vehicle.SOLUTION: A power generation voltage control device for a vehicle which controls a power generation voltage of an alternator so that the power generation voltage reaches a prescribed target voltage at an engine restart at in-traveling eco-run control comprises control means which controls an indication value of the power generation voltage with respect to the alternator becomes smaller than a maximum value of a change speed at which it is determined that the change speed up to the target voltage does not affect the drivability of a driver after an execution condition of the in-traveling eco-run control is established, and that a time necessary for reaching the target voltage from a start of an engine automatic stop at the in-traveling eco-run control becomes shorter than a time minimally necessary for a start of the engine restart from the start of the engine automatic stop.SELECTED DRAWING: Figure 3 |
