[0018] A disadvantage of this filter is that its characteristics must be adapted to the type of starter used
In addition, this magnetic circuit, with a magnetic core that also contains a certain mass, only limits the current to an undefined value, so the battery voltage may drop below the rated value

Embodiment Construction

[0039] According to the stabilizing method for stabilizing the on-board electrical network of a motor vehicle according to the present invention, its principle is as follows: Figure 1a and 1b shown.

[0040] This method is used in the on-board electrical network 2 such as image 3 shown in the stabilization system 1 used, figure 2 is a simplified representation of the on-board electrical network 2 .

[0041] A battery 3 supplies power to this network 2 , to which an electric starter 4 is connected, the electric starter 4 being adapted to be mechanically coupled to the thermal engine of the motor vehicle when the latter is started.

[0042] Various other electrical loads 5 would normally be connected to the network 2 .

[0043] It is these electrical loads 5 that may disrupt their operation due to the voltage drop of the battery 3 at start-up.

[0044] The stabilization method 1 according to the invention is based on the introduction in the power supply circuit of the sta...

Abstract

The method according to the invention is a method of limiting the voltage variation of the battery (3) supplying the on-board electrical network (2) when starting the thermal engine of the motor vehicle by means of an electric starter (4) connected to the on-board electrical network (2) type. According to the method of the invention, a resistive element (6) is connected in series to the battery (3) and the starter (4), said element having a discrete set of values ​​(RDSon1, RDSon2, RDSon3RDSon4) depending on the voltage variation The selected resistor value. According to another feature of the invention, said predetermined values ​​(RDSon1, RDSon2, RDSon3RDSon4) of said discrete set of predetermined values ​​are combined with a predetermined number of harmonic progressions (1, 1 / 2, 1 / 3 and 1 / 4) are proportional to the first few terms.

Description

technical field [0001] In general, the invention relates to the field of starters for heat engines in motor vehicles. More specifically, the invention relates to a stabilization method and system for stabilizing the supply voltage of an on-board electrical network of a motor vehicle at start-up. Background technique [0002] When energizing a starter to ensure starting of a motor vehicle's thermal engine, significant inrush currents close to starter short-circuit current levels, ie, about 1000 amperes, are generated. The intensity of this current then decreases with the acceleration of the starter's armature, which corresponds to the machine's rotor. [0003] Corresponding to this initial current peak, the terminal voltage of the battery drops significantly. Other less pronounced voltage drops then occur during the start-up phase and correspond to the heat engine continuing past top dead center. [0004] The development of starters for automatic shutdown / restart systems f...
