  • Patent number: 8829862
    Abstract: A motor vehicle regulator, including electronic regulation circuits, which can produce an excitation current in accordance with a difference between a set voltage and an output voltage measured at the terminals of an electric battery of the vehicle. The regulation circuits including a programmable signal processing interface for producing a signal, which is representative of the excitation current. The interface receives as input a plurality of signals which are representative of the excitation current. The interface including a device capable of selecting a signal which is representative, from amongst the plurality of representative signals, of the method for applying different forms of processing to the representative signal selected, and a second device for selection of processing to be applied to the representative signal. The representative signal, and the processing to be applied, being selected according to a program provided to the programmable signal interface.

  • Patent number: 8400117
    Abstract: A method for controlling the progressive charge of a motor vehicle alternator. The alternator comprises a stator, a rotor which is provided with an excitation coil, a voltage regulator which acts on an excitation current which is supplied to the excitation coil in order to regulate an output voltage of the alternator, and a device for controlling the progressive charge which, by means of limitation of the excitation current to a maximum value, determines a maximum mechanical torque which the alternator can collect on a thermal engine of the vehicle. The maximum mechanical torque is determined according to a speed of rotation (NALT) of the alternator, and the progressive charge control device comprises a so-called progressive charge return (PCR) signal which indicates the maximum value which the excitation current (lexc) can assume.
