Abstract

A method replaces a controller, particularly a faulty and/or outmoded controller, in an onboard power supply system in a vehicle. The controller to be replaced is replaced by a functional and/or new controller. The controller to be replaced and the new controller are operated by incompatible operating software. In the method at least one software component is exported from a software development environment for the operating software of the controller to be replaced by a data processing apparatus. The software component is converted into a code, which can be imported into a software development environment for the operating software of the functional and/or new controller, by the data processing apparatus. The code is imported into the software development environment of the operating software of the functional and/or new controller by the data processing apparatus. The operating software for the new controller is produced on the basis of the imported code.

Claims

1. A method of replacing a controller, including a faulty controller or an outmoded controller, in an onboard power supply system in a vehicle, in which method of replacement the controller to be replaced is replaced by a new controller, the controller to be replaced and the new controller are operated by incompatible operating software, which comprises the steps of:

exporting at least one software component from a software development environment for an operating software of the controller to be replaced by means of a data processing apparatus;

converting the at least one software component into a code, which can be imported into a software development environment for the operating software of the new controller, by means of the data processing apparatus;

importing the code into the software development environment of an operating software of the new controller by means of the data processing apparatus; and

producing the operating software for the new controller on a basis of a the code imported by means of the data processing apparatus.

2. The method of replacement according to claim 1, wherein the controller to be replaced is a central controller of a vehicle.

3. The method of replacement according to claim 1, wherein the controller to be replaced is connected in a multiplex system being a master/slave system.

4. The method of replacement according to claim 3, wherein the controller to be replaced is connected as a master and actuates at least one multiplex node.

5. The method of replacement according to claim 1, wherein the controller to be replaced is connected in a CAN bus system.

6. The method of replacement according to claim 1, which further comprises producing the operating software for the new controller as a flash file by means of the data processing apparatus.

7. The method of replacement according to claim 1, which further comprises exporting the at least one software component from the software development environment of the operating software of the controller to be replaced as C code by means of the data processing apparatus.

8. The method of replacement according to claim 1, wherein the at least one software component from the software development environment of the operating software of the controller to be replaced contains at least one function block diagram and/or at least one flow controller.

9. The method of replacement according to claim 1, which further comprises producing the code imported by compiling by means of a cross compiler in the data processing apparatus.

10. The method of replacement according to claim 7, which further comprises producing the code imported by compiling the C code into a structured text.

11. The method of replacement according to claim 10, which further comprises compiling the C code into the structured text on a basis of an XML file as a machine-readable reference.

12. The method of replacement according to claim 1, wherein the controller to be replaced is an onboard power supply system computer of a motor vehicle or a commercial vehicle.
