Abstract
In a vehicular electric power generation apparatus having an a.c. generator and an engine, a rotation speed of the a.c. generator at the idling rotation operation of the engine is set to be higher than a rotation speed, at which the driving torque of the a.c. generator becomes a maximum. Thus, the rotation speed of the a.c. generator does not change through the rotation speed at which the driving torque of the vehicle a.c. generator becomes a maximum, even when the rotation speed of the engine is raised high for running of a vehicle. Thus, changes in the load applied to the engine can be restricted.
