Abstract

An engine control system is provided having a control unit and a monitoring module. The monitoring module, together with the control unit, forms one structural unit and is designed as a detachable module having an independent electromagnetic shielding.

Claims

1. An engine control system comprising:

a control unit; and

a monitoring module, the monitoring module and the control unit together forming one structural unit, the monitoring module being a detachable module, detachable from the control unit and having an independent electromagnetic shielding from the control unit, wherein the monitoring module and the control unit are interconnected via a communication interface which includes a galvanic separation.

3. The engine control system as recited in claim 1, wherein the monitoring module is connected via a plug connector device to the control unit.

4. The engine control system as recited in claim 1, wherein the control unit has a first controller and a second controller, the first controller having a first communication interface, a first analog interface and a first current interface, and the second controller having a second communication interface, a second analog interface and a second current interface.

2. An engine control system comprising:

a control unit; and

a monitoring module, the monitoring module and the control unit together forming one structural unit, the monitoring module being a detachable module, detachable from the control unit and having an independent electromagnetic shielding from the control unit, wherein the monitoring module is supplied with current from the control unit via a current interface, a power supply in the control unit or a power consolidation in the monitoring module being designed to be short-circuit and no-load proof.

16. The engine control system as recited in claim 2, wherein the monitoring module is connected via a plug connector device to the control unit.

17. The engine control system as recited in claim 2, wherein the control unit has a first controller and a second controller, the first controller having a first communication interface, a first analog interface and a first current interface, and the second controller having a second communication interface, a second analog interface and a second current interface.

5. A dummy monitoring module for connection to a control unit for an engine control system, the engine control system comprising:

a control unit; and

a functioning monitoring module, the functioning monitoring module and the control unit together forming one structural unit, the functioning monitoring module being a detachable module, detachable from the control unit and having an independent electromagnetic shielding from the control unit, the dummy monitoring module, for purposes of testing, having the same housing and the same plug connector device as the functional monitoring module.

6. The dummy monitoring module as recited in claim 5, wherein a resistor, simulating the power consumption of the functional monitoring module, is provided for a first current interface and second current interface.

7. The dummy monitoring module as recited in claim 5, wherein a first communication interface for a first controller is connected through to second communication interface for a second controller.

8. The dummy monitoring module as recited in claim 5, wherein a first analog interface for a first controller of the control unit is connected via a first test circuit to a second analog interface for a second controller of the control unit.

9. A dummy control unit for connection to a monitoring module for an engine control system, the engine control system comprising:

a functioning control unit; and

a monitoring module, the monitoring module and the functional control unit together forming one structural unit, the monitoring module being a detachable module, detachable from the functional control unit and having an independent electromagnetic shielding from the functional control unit, the dummy control unit, for test purposes, having the same housing and the same plug connector device as a functional control unit.

10. The dummy control unit as recited in claim 9, wherein a current source is provided which supplies the monitoring module with current via a first current interface and a second current interface.

11. The dummy control unit as recited in claim 9, wherein a first communication interface for a first controller is connected through to a second communication interface for a second controller.

12. The dummy control unit as recited in claim 9, wherein an analog interface for a first controller is connected via a second test circuit to a second analog interface for a second controller.

13. The dummy control unit as recited in claim 9, wherein, to determine a minimum attenuation, a first analog interface, a second analog interface, a first communication interface, a second communication interface, a first current interface and a second current interface are interconnected.

14. A method for qualifying the individual components of an engine control system, the engine control system comprising:

a control unit; and

a monitoring module, the monitoring module and the control unit together forming one structural unit, the monitoring module being a detachable module, detachable from the control unit and having an independent electromagnetic shielding from the control unit, in which, for qualification purposes, any components, for which qualification testing is not actively pending are replaced by dummy components.

15. The method as recited in claim 14, wherein the dummy components simulate those functions of the components they have replaced which are required for the particular qualification.
