  • Designed system for troubleshooting the technical problem of the car is a device that takes information from the car and sends it to the server. A series of formulas are executed and displayed in the server. If we want to check the mechanism from the base, our device includes a set It is composed of:
  • Each car has an electrical processing unit (ECU) for every part of electrical components.
  • All cars today have separate sections, at least to manage engine performance, ABS braking system and airbag. These sections are commonly referred to as computers, for example the ABS computer of each ECU receives the required information from the sensors installed in the various sections of these sections, applies the required logics, and performs the operations they expect in these sections, done by their operators apply to those sections.
  • the ECU see a problem in the system performance process, it records the problems in the form of fault codes, and if the fault code remains for a long time, the check light turned on and user is notified that there is a problem.
  • the device that repairmen connect to the OBD port to view the sensor information and faults occured is known as the Car Diag device.
  • the Diag device tries to show the sensor information to the user.
  • the fault codes in the vehicle are recorded in the form of a unique code (eg P0132).
  • the Diag device must provide an interpretation of this fault code to the user, for example: In the number one spark plug of the car, so that the repairman can understand which part of the car has what problem. Sensors and fault codes that occur in each car are different from each other. They do not support all cars.
  • GPS module This module can be used to find out the current position of the car.
  • the user's instantaneous speed is compared to the maximum recorded speed, and if the user's instantaneous speed is higher, it is replaced by the maximum recorded speed so far.

Abstract

L'invention concerne un dispositif qui collecte des informations de la voiture et les envoie au serveur, une série de formules étant exécutées et affichées dans le serveur. Les informations mentionnées concernent toutes les marques de voiture et l'enregistrement de plus de 22 milliers de codes d'erreur dans le logiciel permet d'obtenir un diagnostic complet de la voiture. Le code d'erreur est une explication simple et conviviale permettant d'informer l'utilisateur, dans une large mesure, du problème de la voiture et fournit également une explication complète et globale sur les causes possibles de l'erreur et la manière d'effectuer le dépannage. Selon cette conception, une unité de traitement électrique (ECU), grâce à des capteurs installés dans différentes sections, reçoit les informations requises et applique les logiques requises, les opérations prévues étant alors effectuées dans ces sections par les opérateurs compétents pour ces pièces, lorsque l'ECU identifie un problème dans le processus de performance du système.
