Definitions
- the present invention relates to devices for controlling a vehicle starter switch automobile.
- a starter D which includes an electric motor M mounted between a terminal B + power supply to battery voltage and ground.
- Electric motor supply is controlled by a contactor 1 mounted between said terminal B + and the motor M.
- This contactor 1 is a relay which includes a plunger core (not shown) actuated by a winding call 2 and a holding coil 3 for pushing and maintain a power contact in the closed position 1a.
- the call winding 2 is mounted between the end of the motor M which is opposite to the ground and the winding 3, said coil 3 being connected to ground by its end opposite.
- the coils 2 and 3 are connected to the source of a transistor 4 whose drain is connected to terminal B +, via the ignition key switch 6.
- This transistor 4 is controlled, for example in all or nothing, by a microprocessor 5 - also connected to the supply terminal B + - which injects a voltage of control on the gate of transistor 4.
- This microprocessor 5 is for example, as illustrated in FIG. 1, integrated with relay 1 and transistor 4 inside of the starter housing. It can also be located outside the starter, anywhere in the vehicle.
- the call coil 2 is chosen with very resistance lower than that of the holding coil 3.
- the transistor 4 supplying only the coil of maintenance 3, whose current consumption is low, the heating of said transistor 4 is considerably reduced.
- the transistor 4 is then very quickly destroyed by excessive heating.
- An object of the invention is to overcome this disadvantage.
- said contactor comprising a contact power which controls the supply of the electric motor of the starter and at least one coil which controls the displacement of said contact
- said device comprising a unit for managing the starter control, as well that a transistor, controlled by said unit, which controls the supply of the contactor coil (s), characterized in that the management unit includes means to block the transistor when the fall of voltage at a point supplied with battery voltage between two successive instants following the closing of the contact switch is below a given threshold.
- the invention also relates to a device for control of the power supply of a vehicle starter automobile which comprises a contactor comprising a power contact which controls the motor supply starter motor and at least one coil which controls the movement of said contact, characterized in that that it further comprises a device for controlling contactor of the aforementioned type.
- the control device is of a structure general similar to that illustrated in Figure 1.
- microprocessor 5 On its input which is connected to terminal B + by through the ignition key switch 6, the. microprocessor 5 includes an analog converter digital which allows him to measure the voltage on terminal B + when switch 6 is closed.
- the microprocessor 5 starts the start-up process by closing the transistor 4 (step 15 on the flowchart in FIG. 3) and measures the voltage U 2 in a time T 2 following the closure of switch 6 (step 16).
- the time T 2 corresponds to approximately 10 to 20 milliseconds after the transistor 4 switches to its on state.
- the microprocessor 5 checks the appearance of a significant voltage drop after a time T s , T s generally being between a few tenths of seconds and a few seconds.
- the microprocessor 5 checks whether or not the voltage at time T 2 + T s is greater than U 2 - dU, where du corresponds to the expected minimum voltage drop (step 17).
- microprocessor 5 blocks transistor 4 to avoid deterioration (step 18).
- microprocessor 5 continues the start-up process (step 19).
- the time T s is obviously determined so that the heating remains low enough so that the transistor 4 is not damaged.
- This solution has the advantage of allowing do not damage the power transistor 4 by a extended operation in call mode and does not require no additional components to achieve this function.
- the relay can then have only one coil instead a call coil and a holding coil.
- the device for electronic starter control illustrated in the figure 1 has the advantage of being of the "autonomous" type, that is to say not to require any other electrical connection than those used by conventional starters not electronic, namely a control cable allowing the connection with the vehicle's contact switch, a power supply cable connected to a terminal such as the positive terminal of the battery, and a return to ground by the carcass of the starter.

Abstract
Description
- l'unité de gestion est un microprocesseur dont une entrée à convertisseur analogique/numérique est reliée audit point alimenté à la tension de la batterie et ledit microprocesseur détermine la chute de tension entre lesdits instants successifs suivant la fermeture de l'interrupteur de contact et compare cette chute de tension audit seuil ;
- le transistor est commandé par le microprocesseur de façon tout ou rien ;
- le microprocesseur commande le transistor de façon à réaliser une alimentation progressive de la ou des bobines du contacteur.
- la figure 1, déjà analysée, représente schématiquement un démarreur comportant un dispositif de commande électronisé ;
- la figure 2, qui illustre le principe mis en oeuvre par l'invention, est un graphe sur lequel on a porté l'évolution de la tension de la borne d'alimentation à la tension de la batterie lors du processus de fermeture du contact de puissance du contacteur de la figure 1 ;
- la figure 3 est un organigramme qui illustre différentes étapes mises en oeuvre par le microprocesseur d'un dispositif conforme à la variante illustrée sur la figure 2.
