Abstract

A control unit for controlling or regulating a component, including a processing arrangement for controlling or regulating the component for connecting the control unit to a bus for communicating with a further control unit; an application tool port for connecting the control unit to an application tool for communicating with the control unit; and a connecting arrangement for connecting the application tool port and the bus port so that the application tool is able to communicate via the bus port, and a bus, a motor vehicle, a method, an application tool, and computer program products.

Claims

1. A control unit for controlling/regulating a component, comprising:

a control arrangement, including;

a processing arrangement to control/regulate the component;

a bus port to connect the control arrangement to a bus for communicating with a further control unit;

an application tool port to connect the control arrangement to an application tool for communicating with the control arrangement; and

a connecting arrangement to connect the application tool port and the bus port so that the application tool is able to communicate via the bus port.

2. The control unit of claim 1, wherein the connecting arrangement includes a circuit.

3. The control unit of claim 1, wherein the connecting arrangement is configured via a debug interface of an emulator.

4. The control unit of claim 1, wherein the connecting arrangement is configured by program instructions which are carried out in the control arrangement.

5. The control unit of claim 4, wherein the processing arrangement includes a processor and a memory, and wherein the program instructions are stored in the memory and are carried out by the processor.

6. The control unit of claim 1, wherein the application tool port is configured as an emulator probe port.

7. A bus for at least one control unit, comprising:

at least one control unit for controlling/regulating a component, the at least one control unit including a control arrangement having;

a processing arrangement to control/regulate the component;

a bus port to connect the control arrangement to a bus for communicating with a further control unit;

an application tool port to connect the control arrangement to an application tool for communicating with the control arrangement; and

a connecting arrangement to connect the application tool port and the bus port so that the application tool is able to communicate via the bus port.

8. A motor vehicle, comprising:

a bus for at least one control unit for controlling/regulating a component, the at least one control unit including a control arrangement having;

a processing arrangement to control/regulate the component;

a bus port to connect the control arrangement to a bus for communicating with a further control unit;

an application tool port to connect the control arrangement to an application tool for communicating with the control arrangement; and

a connecting arrangement to connect the application tool port and the bus port so that the application tool is able to communicate via the bus port.

9. A method for operating a control unit, the method comprising:

connecting an application tool port and a bus port of a control unit so that an application tool, which is connected to the application tool port, is able to communicate via the bus port;

wherein the control unit is for controlling/regulating a component, and wherein the control unit includes a control arrangement having;

a processing arrangement to control/regulate the component;

a bus port to connect the control arrangement to a bus for communicating with a further control unit;

the application tool port to connect the control arrangement to the application tool for communicating with the control arrangement; and

a connecting arrangement to connect the application tool port and the bus port so that the application tool is able to communicate via the bus port.

12. The method of claim 9, wherein the connecting arrangement includes a circuit.

13. The method of claim 9, wherein the connecting arrangement is configured via a debug interface of an emulator.

14. The method of claim 9, wherein the connecting arrangement is configured by program instructions which are carried out in the control arrangement.

15. The method of claim 14, wherein the processing arrangement includes a processor and a memory, and wherein the program instructions are stored in the memory and are carried out by the processor.

16. The method of claim 9, wherein the application tool port is configured as an emulator probe port.

10. A computer readable medium having a computer program, comprising:

a program code arrangement having program code for operating a control unit, by performing the following;

connecting an application tool port and a bus port of a control unit so that an application tool, which is connected to the application tool port, is able to communicate via the bus port;

wherein the control unit is for controlling/regulating a component, the control unit including a control arrangement having;

a processing arrangement to control/regulate the component;

a bus port to connect the control arrangement to a bus for communicating with a further control unit;

the application tool port to connect the control arrangement to the application tool for communicating with the control arrangement; and

a connecting arrangement to connect the application tool port and the bus port so that the application tool is able to communicate via the bus port.

11. An application tool for communicating with a control unit, comprising:

an application tool arrangement to communicate via an application tool port in order to communicate via a bus;

wherein the control unit is for controlling/regulating a component, and wherein the control unit includes a control arrangement having;

a processing arrangement to control/regulate the component;

a bus port to connect the control arrangement to a bus for communicating with a further control unit;

the application tool port to connect the control arrangement to the application tool arrangement for communicating with the control arrangement; and

a connecting arrangement to connect the application tool port and the bus port so that the application tool is able to communicate via the bus port.
