COMMUNICATION METHOD AND COMMUNICATION MODULE

摘要

The invention relates to a method of communication between several local applications and a diagnostic application in a motor vehicle as well as to a corresponding communication module, whereby data are transmitted from the local applications to the diagnostic application via a transmission medium. Said method comprises the steps of event-oriented data allocation by said local applications, data acceptance by a communication module, triggered by the event-oriented allocation of said data, data management and preparation by said communication module and transfer of the prepared data from the communication module to the central application. According to the invention, the preparation of all the data, accepted by the local application, within the communication module includes the formatting of data in a data format determined by the central application. Said method and communication module are particularly suitable for carrying out an on-board diagnostic in motor vehicles.
