An electronic unit may have a printed circuit board populated on a main surface of the printed circuit board with at least one electronic component coated with a coating element, where the at least one electronic component is embedded, and where there is a protective element that bears directly on the electronic component on a side facing away from the printed circuit board.

An electronic module, more particularly a control module or sensor module for a motor vehicle transmission, has a circuit board having a first side and a second side facing away from the first side, electronic components arranged on the first side, and a casting compound arranged on the first side. The casting compound covers the electronic components. The circuit board has a through-hole connecting the first side to the second side. A sensor element covering the through-hole is arranged on the first side of the circuit board.

A control module for a vehicle with at least one electric motor and a transmission is provided. The control module has a housing for accommodating a transmission control electronics, a converter electronics for controlling an electric motor, and a cooling body. The housing includes a housing upper part and a housing lower part. The cooling body is arranged between the housing upper part and the housing lower part in such a way that the cooling body forms a part of the housing, that the housing lower part and the cooling body form a media-tight first cavity for accommodating the converter electronics. The converter electronics is thermally conductively connected to the cooling body, and the housing upper part and the cooling body form a media-tight second cavity for accommodating the transmission control electronics. The transmission control electronics is thermally conductively connected to the cooling body.

An electronics module for a transmission control unit may including one or more of the following: a printed circuit board populated with electronic components that are attached to an upper surface and/or a lower surface of the printed circuit board, and electrically connected thereto, and a media-tight protective layer, which covers one or more electronic components and connecting points between the one or more electronic components and the printed circuit board, where there is a cooling element for cooling the electronic components on one side of the printed circuit board, where the cooling element is connected to the printed circuit board and houses the electronic components that are to be cooled, and where the media-tight protective layer covers a transition region between the printed circuit board and the cooling element along the entire periphery of the cooling element.

A control module for a vehicle with at least one electric motor and a transmission is provided. The control module has a housing for receiving a transmission control electronics unit and an inverter electronics unit for controlling an electric motor, and a heat sink. The heat sink is disposed between a housing upper part and a housing lower part in such a manner that the heat sink forms part of the housing. The housing lower part and the heat sink form a medium-tight cavity for receiving the inverter electronics unit. The transmission control electronics unit, conjointly with the plastic casing and the base plate, forms the housing upper part. The housing upper part is connected to the heat sink in a thermally conductive manner such that a heat transport from the transmission control electronics unit via the base plate to the heat sink takes place.

A vehicle control apparatus is disposed inside a housing for accommodating a transmission. The vehicle control apparatus includes a metal base, a resin case, a printed circuit board on which an electronic component mounts, an oil-tight seal member, and a breathable filter. The metal base is made of metal. The resin case is attached to the metal base to form an interior space. The resin case includes a part having a connector penetrating inside and outside of the housing. The printed circuit board is disposed in the interior space. The oil-tight seal member is placed between the metal base and the resin case to surround the printed circuit board. The connector has a ventilation hole. The breathable filter is disposed at a location where the ventilation hole faces outside.

A control unit comprises a processing device with an electrical connection; a diagnostic circuit, which is electrically connected to the connection; and a sheathing, which completely insulates the connection electrically. At the same time, the diagnostic circuit comprises an electrical interface and is configured to sample an electrical signal at the connection and provide the result via the interface.
