Abstract

The prioritization method according to the present invention permits the selection of information providers independently of the selection and functioning manner of the requesting systems, for flexibilization. In a linear prioritization method according to the present invention, a list sorted by rising priority having information providers is sequentially polled, and the first information provider having a request command is selected, this request command is routed on, and the polling is ended. In an additional prioritization method according to the present invention, from a list that is not sorted, having information providers, the information provider having the maximum (minimum) request command is selected or the average request command of the requesters is ascertained. Preferably, the prioritization method according to the present invention is able to be executed using a computer system having a modular system construction.

7. The computer readable medium of claim 6, wherein, in the software architecture, at least one of open interfaces, which are accessible from the outside, and encapsulated interfaces, which are not open to the outside, are integrated.

8. The computer readable medium of claim 6, wherein the requests of the plug-ins include an adaptive cruise control (ACC) request, a driver'"'"'s demand request, a driveability strategy request, and a shift strategy request.

9. The computer readable medium of claim 6, wherein the layer includes the coordinators vehicle coordinator, a vehicle motion coordinator and a powertrain coordinator, the vehicle motion coordinator being where a selection of the plug-ins is performed.

10. The computer readable medium of claim 9, wherein each of the coordinators is connected via interfaces to the plug-ins for communication.

11. The computer readable medium of claim 6, wherein the layer is connected via interfaces for communication with the basic functionalities that act like sensors or actuators.

12. The computer readable medium of claim 6, wherein the plug-ins have a module-like exchangeability so that the prioritization method is flexibly adaptable to different vehicle configurations and control unit configurations, and requests of various systems are centrally introduced in a uniform manner based on system reference variables.

13. The computer readable medium of claim 6, wherein, in the software architecture, at least one of open interfaces, which are accessible from the outside, and encapsulated interfaces, which are not open to the outside, are integrated, wherein the requests of the plug-ins include an adaptive cruise control (ACC) request, a driver'"'"'s demand request, a driveability strategy request, and a shift strategy request, and wherein the layer includes the coordinators vehicle coordinator, a vehicle motion coordinator and a powertrain coordinator, the vehicle motion coordinator being where a selection of the plug-ins is performed.

14. The computer readable medium of claim 13, wherein the layer is connected via interfaces for communication with the basic functionalities that act like sensors or actuators, and wherein the plug-ins have a module-like exchangeability so that the prioritization method is flexibly adaptable to different vehicle configurations and control unit configurations, and requests of various systems are centrally introduced in a uniform manner based on system reference variables.
