Description

La présente invention concerne un appareil diagnostic statique pour dispositif d'allumage, notamment dans un véhicule automobile, constitué essentiellement d'un distributeur d'allumage qui comporte un capteur dont les signaux sont amplifiés par un module électronique pour commander l'état d'une bobine élévatrice de tension. Avec l'augmentation rapide de l'emploi de l'électronique dans les véhicules automobiles et notamment dans leur dispositif d'allumage, est née une difficulté de localisation de défauts éventuels dans le réseau électrique dudit dispositif d'allumage. Des appareils de diagnostic sont donc apparus sur le marché, certains très sophistiqués et conséquemment d'un prix de revient élevé qui apportent des renseignements superflus dans le cas d'un contrôle rapide et d'autres qui nécessitent une attention particulière du manipulateur lors du contrôle pour le branchement de l'appareil sur les éléments à contrôler devant la nécessité de changer le branchement suivant l'élément contrôlé; de plus ces appareils existants peuvent engendrer la destruction d'éléments en parfait état suite à l'absence de moyens appropriés à la recherche d'un défaut éventuel.The present invention relates to a static diagnostic device for an ignition device, in particular in a motor vehicle, essentially consisting of an ignition distributor which comprises a sensor whose signals are amplified by an electronic module to control the state of a voltage raising coil. With the rapid increase in the use of electronics in motor vehicles and in particular in their ignition device, a difficulty has arisen in locating possible faults in the electrical network of said ignition device. Diagnostic devices have therefore appeared on the market, some very sophisticated and consequently of a high cost price which provide superfluous information in the case of a rapid control and others which require a particular attention of the manipulator during the control. for the connection of the device to the elements to be checked in front of the need to change the connection according to the element checked; moreover, these existing devices can cause the destruction of elements in perfect condition following the absence of appropriate means in the search for a possible defect.

Il est connu, notamment par la demande de brevet GB-A-2 019 595, un appareil de test électrique pour système de transmission automatique de véhicules que l'on insère entre la fiche de connexion du système de transmission et son socle. Ce document, décrit un appareil de test électrique pour un système de transmission d'un véhicule et non pour un dispositif d'allumage.It is known, in particular from patent application GB-A-2 019 595, an electrical test apparatus for an automatic transmission system of vehicles which is inserted between the connection plug of the transmission system and its base. This document describes an electrical test device for a vehicle transmission system and not for an ignition device.

D'autre part, le brevet US-A-4 186 337 décrit un appareil de test pour un dispositif d'allumage comprenant une bobine avec une sortie d'allumage, un module électronique d'allumage (connecté à ladite bobine, pour contrôler ladite sortie d'allumage) et un capteur électrique, appareil qui par des moyens visuels signalise le bon ou mauvais état des différents éléments constitutifs du dispositif d'allumage.On the other hand, US-A-4,186,337 describes a test device for an ignition device comprising a coil with an ignition output, an electronic ignition module (connected to said coil, for controlling said ignition output) and an electrical sensor, a device which visually signals the good or bad condition of the various components of the ignition device.

La présente invention a pour but de remédier à ces inconvénients et concerne à cet effet un appareil de diagnostic statique pour dispositif d'allumage de véhicule automobile du type constitué essentiellement d'un capteur d'allumage, d'une bobine élévatrice de tension, d'un distributeur d'allumage et d'un module électronique d'allumage, appareil apte à défi- niret signaler des défauts tels que coupure de fil conducteur d'électricité dans le réseau électrique du dispositif d'allumage et caractérisé en ce qu'il comporte des moyens aptes à assurer son insertion, sans le modifier, dans le réseau électrique existant du dispositif d'allumage et des moyens visuels de signalisation de bon ou mauvais état des différents éléments constitutifs du dispositif d'allumage.The object of the present invention is to remedy these drawbacks and to this end relates to a static diagnostic apparatus for an ignition device of a motor vehicle of the type essentially consisting of an ignition sensor, of a voltage raising coil, of '' an ignition distributor and an electronic ignition module, device capable of defining and signaling faults such as cutting of electrically conductive wire in the electrical network of the ignition device and characterized in that it comprises means capable of ensuring its insertion, without modifying it, into the existing electrical network of the ignition device and visual means for signaling good or bad condition of the various components of the ignition device.

La description qui va suivre en regard des figures annexées fera mieux comprendre comment l'invention peut être réalisée.

  • La figure 1 représente un dispositif d'allumage d'un véhicule et ses différents éléments constitutifs.
  • La figure 2 représente un appareil de diagnostic conforme à l'invention inséré dans un dispositif d'allumage.
  • La figure 3 représente un appareil de diagnostic conforme à l'invention.
The description which follows with reference to the appended figures will make it easier to understand how the invention can be implemented.
  • FIG. 1 represents a device for igniting a vehicle and its various constituent elements.
  • FIG. 2 represents a diagnostic device in accordance with the invention inserted in an ignition device.
  • Figure 3 shows a diagnostic device according to the invention.

De façon connue le dispositif d'allumage représenté à la figure 1 est constitué d'un capteur 3 dont les signaux sont amplifiés par un module électronique 2 pour commander l'état d'une bobine élévatrice de tension 4 dont la tension secondaire est ensuite envoyée à des bougies 9 par l'intermédiaire d'un distributeur 5. Le module 2 comporte un connecteur 8 complémentaire à un connecteur 7 qui correspond au faisceau 6 du dispositif d'allumage du véhicule (figure 2).In known manner the ignition device shown in Figure 1 consists of a sensor 3 whose signals are amplified by an electronic module 2 to control the state of a voltage booster 4 whose secondary voltage is then sent to spark plugs 9 via a distributor 5. The module 2 comprises a connector 8 complementary to a connector 7 which corresponds to the harness 6 of the vehicle ignition device (FIG. 2).

Conformément à l'invention l'appareil de contrôle 1 comporte d'une part un connecteur 30 équivalent au connecteur 7 et donc complémentaire au connecteur 8 et d'autre part un connecteur 20 équivalent au connecteur 8 et complémentaire au connecteur 7, de façon à permettre, sans modification de l'emplacement des différents éléments constitutifs de l'allumage et sans repérage des fils électriques du réseau, l'insertion de l'appareil diagnostic (1) dans le réseau de l'allumage tel que représenté à la figure 2, et ainsi à éviter tout risque d'erreur de branchement.According to the invention the control device 1 comprises on the one hand a connector 30 equivalent to the connector 7 and therefore complementary to the connector 8 and on the other hand a connector 20 equivalent to the connector 8 and complementary to the connector 7, so as to allow, without modifying the location of the various constituent elements of the ignition and without locating the electrical wires of the network, the insertion of the diagnostic device (1) into the ignition network as shown in FIG. 2 , and thus to avoid any risk of connection error.

Un tel appareil de diagnostic comporte essentiellement les deux connecteurs 20 et 30, deux basculeurs 10 et 100, un réducteur de tension 40, un comparateur 50, un générateur de signaux 70, deux systèmes de visualisation 60 et 80.Such a diagnostic device essentially comprises the two connectors 20 and 30, two rockers 10 and 100, a voltage reducer 40, a comparator 50, a signal generator 70, two display systems 60 and 80.

Le connecteur 20 relie l'appareil 1 au capteur 3 par des connexions 21 et 22, à l'alimentation 12v par des connexions 23 et 24 et à la bobine 4 par des connexions 24, 25.The connector 20 connects the device 1 to the sensor 3 by connections 21 and 22, to the power supply 12v by connections 23 and 24 and to the coil 4 by connections 24, 25.

Le connecteur 30 relie l'appareil 1 à l'entrée du module 2 par des connexions 31 et 32, à sa sortie par des connexions 34 et 35 et à l'alimentation 12v par des connexions 33 et 34.The connector 30 connects the device 1 to the input of the module 2 by connections 31 and 32, to its output by connections 34 and 35 and to the 12v supply by connections 33 and 34.

L'utilisation d'un tel appareil est alors la suivante: le moteur du véhicule tant arrêté et le contact coupé il suffit de déconnecter les connecteurs 7 et 8 puis de relier l'appareil 1 par son connecteur 20 au connecteur 7 c'est-à-dire au capteur 3 par les connexions 21 et 22, à la batterie par les connexions 23 et 24 et à la bobine 4 par les connexions 24 et 25.The use of such an apparatus is then as follows: the vehicle engine being stopped and the ignition off, it suffices to disconnect the connectors 7 and 8 and then to connect the apparatus 1 by its connector 20 to the connector 7, that is i.e. to the sensor 3 by connections 21 and 22, to the battery by connections 23 and 24 and to the coil 4 by connections 24 and 25.

Le fonctionnement d'un tel appareil est alors le suivant: les différents interrupteurs 13 à 15 de l'ensemble basculeurs 10 étant dans les positions 13a, 14a et 1 5a telles que représentées en trait plein à la figure 3, l'inverseur 100 étant indifféremment positionné, si le voyant vert 61, du système de visualisation 60, s'allume la tension d'alimentation est correcte, si ce voyant vert 61 reste éteint il existe un problème d'alimentation venant soit de la batterie, soit du faisceau électrique, soit d'un contact électrique, il est donc nécessaire d'effectuer les vérifications avant de poursuivre. Si les voyants 81 et 82 du système de visualisation 80 sont éteints, le capteur 3 est en bon état ainsi que la liaison électrique le concernant, par contre si le voyant 81 est allumé, le capteur 3 est coupé, alors que si le voyant 82 reste allumé cela signifie que le capteur 3 est en court circuit, il est donc nécessaire d'effectuer les modifications adéquates avant de poursuivre les tests.The operation of such an apparatus is then as follows: the various switches 13 to 15 of the rocker assembly 10 being in positions 13a, 14a and 15a as shown in solid lines in FIG. 3, the inverter 100 being indifferently positioned, if the green light 61, of the display system 60, lights up the supply voltage is correct, if this green light 61 remains off there is a supply problem coming either from the battery or from the electric harness , or an electrical contact, it is therefore necessary to carry out the checks before continuing. If the lights 81 and 82 of the display system 80 are off, the sensor 3 is in good condition as well as the electrical connection concerning it, on the other hand if the light 81 is on, the sensor 3 is cut, while if the light 82 stays on this means that sensor 3 is short-circuited, it is therefore necessary to make the appropriate modifications before continuing the tests.

Ces contrôles effectués le connecteur 30 peut être relié au module 2 par l'intermédiaire de son connecteur 8, l'inverseur 101 du basculeur 100 est placé dans la position 101 a, le test est lancé en appuyant quelques secondes sur un bouton poussoir 11 de l'ensemble basculeurs 10, qui alimente un relais 12 lequel commande les interrupteurs 13 à 15 qui viennent dans les positions 13b, 14b et 15b. Pendant ce lancement le système de signalisation 80 clignote et la lampe rouge 62 est allumée. Le bouton poussoir 11 est alors relaché et si la lampe rouge 62 s'éteint et que la lampe verte 61 s'allume la batterie et le capteur, le module et le primaire bobine sont en bon état, le défaut recherché se situe donc au niveau du secondaire bobine ou des bougies du faisceau HT.These checks carried out the connector 30 can be connected to the module 2 via its connector 8, the inverter 101 of the rocker 100 is placed in position 101a, the test is launched by pressing a few seconds on a push button 11 of the rocker assembly 10, which supplies a relay 12 which controls the switches 13 to 15 which come in positions 13b, 14b and 15b. During this launch, the signaling system 80 flashes and the red lamp 62 is on. The push button 11 is then released and if the red lamp 62 goes out and the green lamp 61 lights up the battery and the sensor, the module and the primary coil are in good condition, the fault sought is therefore at the level secondary coil or HT bundle spark plugs.

Si le voyant rouge reste allumé une défaillance existe au niveau du module ou du primaire bobine.If the red light stays on, a fault exists in the module or the primary coil.

L'inverseur 101 est ensuite basculé en sa position 101b, le dispositif est relancé comme précédemment par le bouton poussoir 10 qui est ensuite relâché, si la lampe rouge 62 reste allumée, le module 2 est défaillant, il faut donc le remplacer. Par contre, si la lampe rouge 62 s'éteint et que la lampe verte 61 s'allume, la batterie, le capteur et le module sont en état. On en déduira, que le primaire bobine ou la liaison de la bobine au module sont défaillants, car seuls ceux-ci n'ont pas encore été testé, il faut donc effectuer le réparation.The inverter 101 is then tilted to its position 101b, the device is restarted as before by the push button 10 which is then released, if the red lamp 62 remains on, the module 2 is faulty, it must therefore be replaced. On the other hand, if the red lamp 62 goes out and the green lamp 61 comes on, the battery, the sensor and the module are in good condition. It will be deduced therefrom that the primary coil or the connection of the coil to the module are faulty, because only these have not yet been tested, so repair must be carried out.

Il n'y a plus qu'à couper le contact, à déconnecter l'appareil 1 et à relier les connecteurs 7 et 8.All you have to do is switch off the ignition, disconnect the device 1 and connect the connectors 7 and 8.

Un tel appareil à l'avantage essentiel d'être d'un emploi simple et de permettre une localisation par étape de tout défaut éventuel d'un dispositif d'allumage.Such an apparatus has the essential advantage of being simple to use and of enabling location by stage of any possible defect in an ignition device.
