Definitions
- the invention relates to a device for controlling and monitoring processes in the motor vehicle, in particular ignition and fuel injection processes.
- WO 83/02 836 discloses a control device for a motor vehicle with a microcomputer, which has a self-diagnosis system with a fault memory, the faults detected being able to be made visible in the motor vehicle using simple display systems.
- a large number of storage spaces are required, which make the system complex and expensive.
- the diagnostic effort in such a large-scale device must be limited in order to keep the costs of the system within realistic limits.
- the device according to the invention with the characterizing feature of the main claim has the advantage that an inexpensive series control device can be used without a diagnostic device. If a diagnosis is to be carried out or an error occurs, the serial control unit can be easily exchanged by simply plugging it in with a workshop control unit (diagnostic microcomputer) which, in addition to the necessary control functions, also has very complex diagnostic functions and error memory. If the error does not occur immediately, this workshop control unit can also be left in the motor vehicle for a longer period of time in order to record and record the error. Errors identified in this way can then be read out in the workshop via an evaluation device. Thus, information about errors and malfunctions can be recorded while driving, although a simple and inexpensive series control device is used in normal operation.
- a workshop control unit diagnostic microcomputer
- E ⁇ n. Series control unit designed as a microcomputer 10 is connected via a plug-in connection 11 both to four triggering devices 12 to 15 and to five transmitters 16 to 20.
- triggering devices 12 to 15 are connected via a plug-in connection 11 both to four triggering devices 12 to 15 and to five transmitters 16 to 20.
- An ignition output stage 12, injection output stages 13, an output stage 14 for controlling an automatic transmission and a control output stage 15 for an anti-lock braking system are provided as triggering devices.
- the number of these triggering devices or functions can of course be expanded or reduced as desired.
- Such a system for controlling the ignition and fuel injection is described in more
- a diagnostic microcomputer 22 can alternatively also be inserted into the plug connection 11.
- This has a connection 23, via which it can be connected to an external evaluation device 24, for example in the workshop.
- This evaluation device 24 can be, for example, a data display device and / or a printer and / or a simple display instrument.
- the standard microcomputer 10 which has no diagnostic functions, is connected to the plug connection 11 and, depending on the parameters detected, generates the necessary control functions for the triggering devices 12 to 15. If an error occurs or the vehicle in which this system is installed becomes , brought into the workshop for inspection, the microcomputer 10 is unplugged and the diagnostic microcomputer 22 is inserted in its place.
- This diagnostic microcomputer contains at least the same control functions as the microcomputer 10 and can therefore work independently.
- a large number of variable control functions are preferably provided for different types of motor vehicles, the connected sensors and triggering devices initially being queried for adaptation via the inputs and outputs to determine what type of motor vehicle it is. The necessary control functions and memory locations or memory maps are made available accordingly.
- a large number of diagnostic functions are contained in a diagnostic program, by means of which the transmitters 16 to 20, the connecting lines and the triggering devices 12 to 15 are checked. The results are stored in non-volatile memories. If an error occurs only sporadically, this diagnostic microcomputer can remain in the vehicle as a replacement device until this error occurs again and is saved. The stored errors and malfunctions can then be called up via the evaluation device 24 which can be connected in the workshop.
- the standard microcomputer 10 used as a control device therefore does not have to be burdened with any costs and assembly costs for diagnosis, while the diagnostic microcomputer, which as a workshop device is not so important in terms of effort and costs, has a large number of complex functions and storage options can be equipped. This provides extensive self-diagnosis options without individual effort. Due to the large number of possible functions in the diagnostic microcomputer, complex interfaces can be avoided.

Abstract
Un dispositif pour la commande et la surveillance des processus se déroulant dans un véhicule motorisé, surtout les processus d'allumage et d'injection du carburant, dans lequel un micro-ordinateur de série (10), intégré dans le véhicule pour le calcul de ces processus en fonction des paramètres du véhicule, est relié, par des prises enfichables (11), à au moins un émetteur (16 à 20) pour déterminer l'état d'un paramètre et à un dispositif de déclenchement au moins (12 à 15) pour ces processus. Pour le diagnostic le micro-ordinateur (10) est remplacé par un micro-ordinateur de diagnostic (22), introduit de manière alternée dans les prises (11); l'ordinateur de diagnostic renferme, en plus de fonctions de diagnostic, les fonctions du micro-ordinateur de série (10). Les erreurs ou les fonctions d'erreurs déterminés sont stockées dans une mémoire d'erreurs et peuvent être transférées à un dispositif externe d'évaluation de préférence dans un atelier, par une connexion (23) du micro-ordinateur de diagnostic (22). Par conséquent, le micro-ordinateur de série (10) n'entraîne pas de frais ou de dépenses de fourniture pour le diagnostic; de plus, on peut effectuer dans l'ordinateur de diagnostic (22), fonctionnant de manière autonome, des fonctions de diagnostic très coûteuses, ainsi que le stockage des erreurs; de plus, des erreurs peuvent être saisies au cours d'une longue période pendant le fonctionnement normal de la voiture.A device for controlling and monitoring the processes taking place in a motor vehicle, especially the ignition and fuel injection processes, in which a standard microcomputer (10), integrated in the vehicle for the calculation of these processes depending on the parameters of the vehicle, is connected, by plug-in sockets (11), to at least one transmitter (16 to 20) to determine the state of a parameter and to at least one triggering device (12 to 15) for these processes. For diagnosis, the microcomputer (10) is replaced by a diagnostic microcomputer (22), inserted alternately in the sockets (11); the diagnostic computer includes, in addition to diagnostic functions, the functions of the serial microcomputer (10). The errors or the error functions determined are stored in an error memory and can be transferred to an external evaluation device, preferably in a workshop, by a connection (23) of the diagnostic microcomputer (22). Consequently, the serial microcomputer (10) does not entail any costs or expenses of supply for the diagnosis; in addition, very expensive diagnostic functions can be performed in the diagnostic computer (22), operating independently, as well as error storage; moreover, errors can be caught over a long period of time during normal operation of the car.
