| 20140125296 | METHOD FOR CONTROLLING THE RESISTING TORQUE OF A MOTOR VEHICLE ALTERNATOR, AND SYSTEM FOR IMPLEMENTING THIS METHOD - A method is disclosed to produce a supply voltage (B+) in an on-board system of a vehicle in response to an excitation current (I_ROTOR) applied to a rotor of the alternator. The method is of the type that consists in: limiting the resisting torque by determining a maximum cyclic ratio (DC_C_LIMIT) of the excitation current as a function of variables taken from a group containing a rotational speed (V_ROTOR) of the rotor, a temperature of the rotor, the excitation current and the supply voltage (B+). The maximum cyclic ratio is determined as a function of at least two of the variables in the group. According to one specific embodiment, the variables are rotational speed and temperature. According to another embodiment, the variables are rotational speed and excitation current. | 05-08-2014 |
| 20140340055 | METHOD AND SYSTEM FOR CONTROLLING A MOTOR VEHICLE ALTERNATOR, AND MOTOR VEHICLE ALTERNATOR INCLUDING SUCH A SYSTEM - A method for controlling a motor vehicle alternator, in which an error value, resulting from the comparison between the voltage produced by the alternator and a set value, is processed in a filtering means by applying a transfer function, which determines a gain to be associated with the error value on the basis of the rotational frequency of the alternator, in order to control the adjustment of the field current allowed by the alternator. The transfer function of the filtering means is modified on the basis of the rotational speed of the alternator by attenuating the gain over a given frequency range when the rotational speed decreases. | 11-20-2014 |
| 20150188469 | METHOD AND SYSTEM FOR CONTROLLING THE PROGRESSIVE CHARGING OF AN ALTERNATOR OF A MOTOR VEHICLE, AND MOTOR VEHICLE ALTERNATOR COMPRISING SUCH A SYSTEM - A method carried out in an alternator supplying a supply voltage slaved to a nominal value by means of a control loop controlling an excitation current of the alternator via a pulse width modulation of the current. The method limits the power draw by the alternator from the heat engine of the vehicle in a progressive response phase (LRC_Ph) with a higher supply voltage drop to a pre-determined triggering threshold by only authorizing progressive increases of a current cyclic ratio (DC_EXC) of the excitation current from an initial cyclic ratio (DC_I) to an expected cyclic ratio calculated by the control loop. According to the invention, at the beginning of the progressive response phase, the initial cyclic ratio is increased by a pre-determined jump only if the regulation loop does not have an acyclism. | 07-02-2015 |
