Abstract

A computer project management system and method for the creation of an electronic control unit software is provided. The system has a software architecture tool configured to design a graphical model of an electronic control unit for a motor vehicle. A behavior model tool converts the graphical model into a computer readable production code. A software container has a file generated based on the electronic control unit. A container manager compares the software container with a prior software container during the importation or exportation of the software container to or from the software architecture tool or the behavior model tool, and a comparison list is generated indicating whether interface modifications for the electronic control unit were made. The comparison list is then displayed to a user on a display screen.

storing a rule set in the first memory region and/or in the second memory region, the exporting of the first file collection and/or the importing of the second file collection occurs by the respective management unit according to the rules defined in the rule set;

defining different types of files and categories for the different types of files in the rule set; and

assigning, via the first management unit, at least one category to the files during the incorporation of files in the first file collection.

2. The method according to claim 1, wherein it is established in the rule set for each category whether the files assigned to the category for export purposes in the first file collection are overwritten/updated, deleted, or left intact.

3. The method according to claim 1, wherein it is established in the rule set for each category whether the files assigned to the category in the second file collection during import of the first file collection into the second development project are overwritten/updated, deleted, or left intact.

4. The method according to claim 1, wherein the file collection exchange occurs from the second development project to the first development project and whereby in the rule set it is considered whether the file collection exchange occurs from the first to the second development project or from the second to the first development project.

5. The method according to claim 1, wherein the rule set can be configured by a user.

6. The method according to claim 1, wherein the computer system has a file collection management unit with a graphical user interface (GUI) and access to the first and/or second memory area, which shows the first file collection and/or the second file collection, and wherein the files included in the respective file collection are listed hierarchically and whereby the assigned category is indicated for each file.

7. The method according to claim 1, wherein the first file collection and the second file collection are shown in a comparison mode.

8. The method according to claim 1, wherein by means of the file collection management unit a comparison and/or merge of the first file collection and the second file collection is performed.

9. The method according to claim 6, wherein the rules for the rule set can be configured by means of the GUI of the file collection management unit by a user.

10. The method according to claim 1, wherein the rules for the rule set can be input by a user by means of a symbolic language.

11. The method according to claim 1, wherein the rules that apply to a file in a concrete scenario are visualized to a user for inspection.

12. The method according to claim 11, wherein the rules are visualized to the user via a display device.

13. The method according to claim 1, wherein the first and/or the second management unit is/are connected to a version control program or an enterprise data management program.

14. The method according to claim 1, wherein the files belonging to the first development project or the files belonging to the second development project comprise virtual electronic control devices.

15. The method according to claim 1, wherein the first and the second development environments each have a RAM memory in addition to the respective first memory region and the second memory region, wherein during ongoing operation of the first or the second development environment a first subset of the files belonging to the corresponding development environment is also stored in the corresponding RAM memory, wherein the corresponding development environment has access to the corresponding files in the particular RAM memory, and wherein the first management unit, to update the first file collection, performs a comparison between the files in the RAM memory of the first development environment and the files belonging to the first development project in the first memory region of the first development environment.

16. The method according to claim 6, wherein the file collection management unit is realized, without the first development environment or the second development environment having been started.

17. A project management computer system comprising:
