ELECTRIC POWER GENERATION CONTROL SYSTEM FOR HYBRID AUTOMOBILE

摘要

A control device judges whether electric power generation of an electric generator is to be performed, depending on a state of a storage battery. When permitting the electric power generation, the control device sets an internal combustion engine rotational speed by which the electric generator is capable of performing electric power generation equivalent to an output required for cruising, depending on a traveling state, and also sets an additional internal combustion engine rotational speed by which the electric generator is capable of performing electric power generation according to a required electric power amount, from a vehicle state and the traveling state. The control device controls the internal combustion engine and the electric generator depending on the internal combustion engine rotational speed and the additional internal combustion engine rotational speed.
