Control device and method for producing a control device for a motor vehicle

An automatic transmission for a motor vehicle, comprising:

• a housing;
• and
• a control device arranged within the housing, the control device including:
• a first circuit mount including electrical components that are electrically conductively connected to one another;
• and
• a second circuit mount including electrical components that are electrically conductively connected to one another,
• wherein the first circuit mount and the second circuit mount are electrically conductively connected to one another,
• wherein the second circuit mount is thermally conductively and fixedly connected to a fluid-tight thermally conductive mount element,
• wherein the first circuit mount has a recess, the second circuit mount being arranged in the recess, and
• wherein the mount element (i) is arranged in the recess, (ii) has a better thermal conductivity than the first circuit mount, (iii) is configured to be thermally conductively connected to a heat sink, and (iv) is integrated into an inner region of the first circuit mount in a fluid-tight manner.

A method for producing a control device for a motor vehicle, comprising:

• embedding a mount element into a first circuit mount during the production process of said circuit mount in a fluid-tight manner,
• exposing a central region of the mount element by producing a recess,
• positioning and connecting a second circuit mount together with its electrical components in a highly thermally conductive manner,
• connecting the first circuit mount and the second circuit mount in an electrically conductive manner,
• fixedly connecting a cover structure to the first circuit mount in a fluid-tight manner, and
• connecting electrical components to the first circuit mount in an electrically conductive manner.
