ELECTRICAL GENERATION CONTROL APPARATUS AND CONTROL METHOD IN A VEHICLE

摘要

A vehicle has an alternator (20) and a motor-assisted turbocharger (MAT) (10). A electrical generation amount control apparatus (24) calculates the electrical generation efficiency ?m of the MAT (10) and the electrical generation efficiency ?a of the alternator (20) and, based on these values, calculates the electrical generation instruction amount 1 to be demanded of the MAT (10) and the electrical generation instruction amount 2 to be demanded of the alternator (20). Of the electrical generation instruction amount 1 and the electrical generation instruction amount (2) are calculated to give priority in electrical generation to which of the MAT 10 and the alternator (20) has the higher electrical generation efficiency.
