<p>#CMT# #/CMT# The method involves calculating an output value by calculating two terms, proportional to corresponding input values, of an equation and by subtracting the terms from each other. The output value represents a current delivered by an alternator of a motor vehicle. One of the input values represents an excitation current of the alternator and the other input value represents a speed of rotation of the alternator. #CMT# : #/CMT# An independent claim is also included for a motor vehicle alternator comprising a unit for controlling voltage delivered by the alternator, comprising a device for estimation of current delivered by the alternator. #CMT#USE : #/CMT# Used in a Motorola 6805(RTM: Not defined) microcontroller for estimating current delivered by an alternator-starter or an alternator of a motor vehicle (claimed) for managing slowing down of a heat engine and/or for managing a charge balance of a battery of the vehicle. #CMT#ADVANTAGE : #/CMT# The method allows to estimate the current delivered by the alternator or the alternator-starter of the motor vehicle in a simple and precise manner from the measurement of the excitation current of the alternator, while permitting to adjust the result of the estimation to the real current value of the alternator of the vehicle. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a simplified view of an alternator. 1 : Rotor 2 : Stator 3 : Rectifier bridge 4 : Load 11, 22 : DC current sources 23 : Resistor 31, 41 : Direct voltage sources.</p> |
