Alternator torque controlling method for motor vehicle, involves controlling torque of alternator by direct control of excitation of alternator, and establishing excitation of alternator after comparison of setpoint value with parameter

摘要

The method involves controlling a torque of an alternator of a motor vehicle by a direct control of excitation of the alternator. Excitation of the alternator is established after a comparison of a setpoint value determined from a reference torque (C-CONS) with a parameter i.e. excitation voltage, that is obtained from the excitation of the alternator, where the parameter is obtained from a measured excitation current (I-EXC-MES). An independent claim is also included for an alternator torque controlling system comprising a torque adjusting device.
