An energy buffer drive apparatus alternates between a state wherein a vehicle is caused to travel while rotational energy of a heat engine is intermittently stored in a flywheel, and a state wherein the vehicle is caused to travel using only the stored energy. In a process where the flywheel speed is reduced by the vehicle traveling using the rotational energy of the flywheel alone, the point in time when the heat engine again begins to supplement rotational energy to the flywheel is determined from (1) a speed ratio e=N2/N1 of the revolution speed N1 of the input shaft and the revolution speed N2 of the output shaft in the continuously variable transmission always being smaller than the maximum allowed speed ratio, and (2) the output power of the heat engine exceeding the demanded power for a power train when the heat engine starts supplying energy once more.
