Abstract

A multi-layered module-type software layout known from the related art has been further developed for vehicles, and in addition, definite procedures are given for putting it into practical use. According to the present invention, to do this, a computer system is described having a software architecture (FIG. 4) that includes practical function assignments and interfaces having exchangeable modular plug-ins. With the aid of a prioritization method according to the present invention, these plug-ins may be polled independently of the number and functioning of the requesting systems for flexibilization. A method according to the present invention for powertrain control of a motor vehicle is divided into 5 phases from the characterization of environmental influences to the approach to the optimal operating point. In a computer system according to the present invention, having an object-oriented software system, this method may also be applied.

Claims

1. A computer system comprising at least one processor and at least one memory for controlling, especially for coordinating powertrain control for a motor vehicle, having a software architecture that has essentially the following elements or components:

an operation system and specific services having an operating system and specific services as the basis for all other elements and applications,

a basic functionality for carrying out universal requests,

a layer for coordinating tasks for basic functionalities of the base functionality and for linking in plug-ins,

at least one plug-in for carrying out practical tasks or functions which go beyond the basic functionality and are coordinated by the layer, the plug-ins being especially modularly exchangeable.
