Abstract
Official abstract text for this publication.
An alternator driving apparatus for driving an alternator may include a crank pulley mounted on a crank shaft of an engine, an alternator pulley connected to the crank pulley through a driving belt, an alternator shaft connected between the alternator and the alternator pulley, and a rotation speed varying mechanism configured to vary a rotation speed of the alternator shaft.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for controlling an alternator driving apparatus, wherein the alternator driving apparatus comprises a crank pulley mounted on a crank shaft of an engine, an alternator pulley connected to the crank pulley through a driving belt, an alternator shaft connected between the alternator and the alternator pulley, and a rotation speed varying mechanism configured to vary a rotation speed of the alternator shaft, the method comprising: monitoring an external temperature, a current of a battery, a speed of the engine; in any one of a condition in which an external temperature is not less than a predetermined temperature, a condition in which the current of the battery is not less than a predetermined current, and a condition in which the rotation speed of the engine is a high or middle speed which is higher than a predetermined speed, the alternator shaft is rotated at a same rotation speed as a rotation speed of the alternator pulley. 2. The method of claim 1 , wherein in any one of a condition in which an external temperature is not more than a predetermined temperature, a condition in which the current of the battery is not more than the predetermined current, and a condition in which the rotation speed of the engine is a speed lower than the predetermined speed, the alternator shaft is rotated at a rotation speed which is higher than the rotation speed of the alternator pulley.
