Description

Technical Field

[0001] The invention relates to a control unit housing and a control unit device, in particular for a vehicle, as well as a method for producing a corresponding control unit housing. Background Art

[0002] The vehicle's controllers can be designed redundantly so that even if one of the controllers fails, at least one safety-related function of the vehicle can continue to be reliably controlled. The controllers can be located at different locations in the vehicle to additionally achieve spatial separation. It is therefore unlikely that all controllers will fail simultaneously, for example due to environmental influences.

[0003] To enable redundant operation of the controllers, data communication between them is required. The controllers are then connected to one another via connecting cables. These connecting cables are only required to monitor for malfunctions. Therefore, it is advantageous to keep these connecting cables as short as possible, thus minimizing costs.

[0004] If the controllers are arranged in the same housing, a particularly short connection can be achieved. However, all controllers arranged in the same housing can then be damaged due to the same external influences, such as, for example, water penetrating into the housing. Summary of the Invention

[0005] Against this background, the solution presented here provides a control housing and a method for producing a corresponding control housing according to the independent claims. Advantageous developments and improvements of the solution presented here are derived from the description and are described in the dependent claims.

[0006] Advantages of the present invention.

[0007] In the solution presented here, a housing for at least two controllers is divided into two or more fluid-tightly separated chambers. The chambers are separated by at least one fluid-tight partition wall. Fluid-tight communication lines are integrated into the partition wall to enable data communication between the controllers.

[0008] The solution presented here allows for a cost-effective connection between at least two redundant controllers. The controllers are each arranged in a sealed chamber of a common housing. No additional cables are required for the connection.

[0009] According to a first aspect of the invention, a controller housing is proposed, wherein the controller housing has at least two chambers separated from each other in a fluid-tight manner by a partition wall, wherein at least one signal transmission element for transmitting data between the chambers is arranged in the partition wall, wherein the signal transmission element is embedded in the plastic material forming at least the partition wall.

[0010] According to a second aspect of the present invention, a controller device is described, comprising a controller housing according to an embodiment of the first aspect of the present invention and at least two controllers. The controllers are accommodated in different chambers of the controller housing and are connected to each other via signal transmission elements for data transmission.

[0011] According to a third aspect of the present invention, a method for producing a control housing is proposed, wherein at least one signal transmission element for data transmission is embedded in the plastic material of a partition wall between two chambers.

[0012] The concept of the embodiments of the present invention can be considered to be based in particular on the concepts and findings described below.

[0013] The controller housing can be a common housing for two or more controllers or two or more subcontrollers. The controller housing can have a housing lower part or a tray. The interior of the housing lower part can be divided into at least two chambers by at least one partition wall made of plastic material. Each chamber can have its own housing upper part or its own cover. The cover can be sealed fluid-tightly around the edge of the chamber. The edge is formed at least partially by the at least one partition wall. Alternatively, the housing lower part can have a one-piece housing upper part or a one-piece cover, to which the partition wall is sealed fluid-tightly.

[0014] The housing lower part and / or the housing upper part can be made of plastic material or metal material. If the housing lower part is made of plastic material, the partition wall can be connected to the housing lower part in one piece. The housing lower part and the partition wall can then be made in the same mold in the process.

[0015] At least one signal transmission element can be embedded in the partition wall. In particular, a group of signal transmission elements can be embedded in the partition wall.

[0016] At least one circuit board can be arranged in each chamber, each of which has electronic components of one of the controllers or one of the subcontrollers. The circuit board can be electrically connected to at least one signal transmission element. For example, the circuit board can be plugged and / or soldered to at least one plug contact of the signal transmission element.

[0017] At least one signal transmission element can be at least partially pre-injection-coated and embedded in the plastic material in the pre-injection-coated state. In particular, a group of signal transmission elements can be pre-injection-coated. The pre-injection-coated signal transmission elements can be referred to as a pre-injection-coated part. The pre-injection-coated signal transmission elements are already arranged in their final relative positions within the pre-injection-coated part. To this end, the group of signal transmission elements can be arranged in a mold cavity of a pre-injection-coated mold and, when the mold cavity is filled with plasticized plastic material, are surrounded by the plastic material and embedded in the plastic material forming the pre-injection-coated part, at least in predetermined sections. The pre-injection-coated part can, for example, include auxiliary geometric structures in areas formed from the plastic material that simplify insertion of the pre-injection-coated part into the mold cavity of the mold used to produce the partition wall. This eliminates the need for a separate receptacle in the mold to hold the signal transmission elements during filling of the mold cavity. The receptacle can be provided by the pre-injection-coated part. The plastic material of the pre-injection-coated part can be the same as the plastic material used to produce the partition wall. As a result, the plastic material of the pre-injection coating can at least partially melt during the production of the partition wall and mix with the plastic material of the partition wall.

[0018] At least one signal transmission element can be implemented as an embedded electrical conductor, which has an exposed connection area for each cavity. In the simplest case, the electrical conductor can be a length of wire. The end area of the wire can constitute the connection area. The wire can be inserted into the receiving part of the injection molding mold with its end area so that the wire is arranged transversely to the partition wall. The plastic material of the partition wall flows around the conductor and surrounds it. In this case, the plastic material is connected to the conductor in a fluid-tight manner. The plastic material is then simultaneously an electrical insulator for the conductor. The electrical conductor can also be implemented as part of a stamped grid. Multiple conductors can be manufactured continuously in the stamped grid. The individual conductors can be separated from each other during the manufacturing process so as to be electrically isolated from each other. The connecting tabs of the stamped grid connecting the individual conductors can, for example, be cut and / or bent when the injection molding mold is closed. Similarly, the connecting tabs can be melted and / or evaporated by a targeted overload voltage applied between at least two of the conductors.

[0019] The conductor can have a melting region in which the conductor cross-section is reduced compared to the connection region. The conductor cross-section can be dimensioned so that the melting region melts if the current flowing through the conductor exceeds the signal flow of the data transmission by a certain tolerance. The melting region can be embedded in the plastic material, thereby protecting the melting region from mechanical loads. The melting region allows the conductor to function as a fuse and disconnect the controllers from each other in the event of an overvoltage or fault.

[0020] The conductor can be implemented at least partially as a positive temperature coefficient resistor (PTC). The PTC resistor can be configured so that if the current flowing through the conductor is greater than the signal flow of the data transmission by a tolerance, the resistance of the PTC resistor increases. PTC resistors have a disproportionately high change in their resistance when their temperature changes. In particular, the resistance increases dramatically at temperatures above a temperature determined by the material composition of the PTC resistor. Even in the event of an overload voltage, the current flowing through the PTC resistor is limited by the increased resistance. This allows the controller to be protected in the event of an overload voltage.

[0021] At least one signal transmission element can be implemented as a galvanically isolated inductive coupler. The inductive coupler can be a small transformer. The inductive coupler can have two transformer windings or coupler windings. Each transformer winding can have two terminals, each accessible from one of the chambers. Therefore, there is no conductive connection between the chambers. When current flows through one of the transformer windings, an electromagnetic field is generated. Changes in the electromagnetic field, in turn, induce a current in the other transformer winding. This allows for the transmission of AC signals.

[0022] At least one signal transmission element can be implemented as a digital isolator with electrical isolation. A digital isolator can be referred to as an optocoupler. An optocoupler can include at least one light source and at least one optoelectronic element. The light source can be controlled by an electrical signal to transmit an optical signal. The optoelectronic element receives the optical signal and converts it back into an electrical signal. Constant signals can also be transmitted via an optocoupler.

[0023] Furthermore, at least one plug housing of the controller housing can be integrally formed with the partition wall. In particular, the plug housing can be integrally connected to the partition wall for each chamber. Further plastic components of the controller housing can be integrated into the plastic component of the partition wall. While this may make the mold profile for the partition wall more complex, it can save on separate molds for the plug housings. Electrical conductors can also be embedded in the plastic material of the plug housing. The electrical conductors of the plug housing can also be configured for transmitting electrical power, thus having a larger line cross-section than the signal transmission elements passing through the partition wall.

[0024] The lid for closing the chamber can be designed as a single piece. The lid can have a sealing geometry in the region of the partition wall for sealing against the partition wall. The sealing geometry can be, for example, a deepening for the head of the partition wall. This allows the partition wall to be inserted into the lid and sealed against the lid.

[0025] Furthermore, at least one power transmission element for transmitting electrical power can be arranged in the partition wall and embedded in the plastic material. The power transmission element can have a significantly larger line cross-section than the signal transmission element. A multiple of the through-current can flow through the power transmission element for data transmission. The power transmission element can, in particular, be designed as a flat conductor made of sheet material. The power transmission element can be molded into the same stamped grid as the signal transmission element. During the production of the partition wall, the power transmission element can be electrically separated from the signal transmission element.

[0026] It should be noted that some of the possible features and advantages of the present invention are described herein with reference to different embodiments. Those skilled in the art will recognize that the features of the controller and the method can be combined, adapted or interchanged in a suitable manner to achieve further embodiments of the present invention.

[0034] Figure 1A diagram of a controller housing 100 according to one embodiment is shown. Controller housing 100 has two fluid-tightly separated chambers 104 for two controllers 102 or two sub-controllers. Chambers 104 are separated from each other by partition walls 106 made of plastic material. One of controllers 102 is located in each chamber 104. At least one signal transmission element 108 for data transmission between controllers 102 is embedded in partition walls 106.

[0035] The controller 102 is disposed on a circuit board 110 . The circuit board 110 is disposed in each chamber 104 . The controller 102 is independent and redundant. The controller 102 communicates via a signal transmission element 108 .

[0036] The signal transmission element 108 is arranged in the housing lower part 112 of the control housing 100. The two chambers 104 are closed in a fluid-tight manner by a common cover 114. The cover 114 also seals at the partition wall 106 in order to separate the chambers 104 from each other in a fluid-tight manner.

[0037] In one exemplary embodiment, a plurality of signal transmission elements 108 are embedded in the plastic material of the partition wall 106. The signal transmission elements 108 are arranged spaced apart from one another in the partition wall 106 and are therefore electrically isolated from one another.

[0038] In one embodiment, the partition wall 106 and the at least two plug housings 116 are designed as components made of plastic material. The rest of the control housing 100 is made of metal material. The plug housings 116 are arranged in different chambers 104 and are each associated with one of the control units 102.

[0039] In one exemplary embodiment, the printed circuit board 110 is clamped between the housing lower part 112 and the cover 114 or the housing upper part. The printed circuit board 110 is not clamped in the region of the partition wall 106 .

[0040] In one embodiment, the signal transmission element 108 is configured as an electrical conductor 118. The electrical conductor is, for example, a wire or a tab made of a metallic material. The end region of the electrical conductor is not embedded in the partition wall 106 but instead extends into the chamber 104. The end region is designed as a connection region 120 of the signal transmission element 108 and is connected to the printed circuit board 110.

[0041] In one embodiment, the signal transmission elements 108 are formed continuously as a stamped grid from sheet material in a stamping and bending process. After the stamping and bending process, the individual signal transmission elements 108 are connected to one another via temporary connecting tabs. The stamped grid is continuously embedded in the plastic material of the partition wall 106. All signal transmission elements 108 are then held in their proper positions by the connecting tabs during embedding. After embedding, the connecting tabs are severed to electrically isolate the signal transmission elements 108 from one another. This separation can be achieved, for example, mechanically using a separating tool or thermally by targeted energization.

[0042] Figure 2 The diagram shows a group 200 of pre-injection-coated electrical conductors 118 as signal transmission elements 108 on a control housing 100 according to one embodiment. The electrical conductors 118 essentially correspond to Figure 1 In addition, the electrical conductors 118 are embedded in a pre-injection encapsulation part 202 made of plastic material. The pre-injection encapsulation part 202 is made in a simple pre-injection encapsulation mold or injection molding mold for pre-injection encapsulation. Before the partition wall is manufactured, the pre-injection encapsulation part 202 is placed in the partition wall mold or injection molding mold for manufacturing the partition wall. The positions of all pre-injection encapsulated electrical conductors 118 are predetermined by the pre-injection encapsulation part 202 and do not need to be specified by an additional receiving part of the partition wall mold. In addition, the pre-injection encapsulation part 202 can be placed in the partition wall mold by a single operation. Otherwise, each electrical conductor 118 would require independent operation or a complex manipulator with multiple connection possibilities.

[0043] In one embodiment, the plastic material of the pre-injection package 202 is Figure 1 The same plastic material as the plastic material of the partition wall in the mold is used. Therefore, when filling the partition wall mold, the plastic material of the pre-injection envelope 202 is plasticized or at least heated intensely at least at the surface of the pre-injection envelope 202. As a result, the plastic material can be integrally connected, and no interface can be detected between the pre-injection envelope 202 and the partition wall.

[0044] The electrical conductors 118 are arranged parallel to one another in a common plane. The end regions of the electrical conductors are bent upward substantially perpendicularly to the plane to form the connection regions 120. The connection regions 120 protrude from the pre-injection package 202 and are exposed. Each second connection region 120 is arranged slightly laterally offset from its adjacent connection region 120 to increase the spacing between the exposed connection regions 120.

[0045] In one embodiment, the electrical conductors 118 are continuously produced as a stamped grid from a sheet material in a stamping and bending process. After the stamping and bending process, the individual electrical conductors 118 are connected to each other by temporary connecting tabs. The stamped grid is continuously embedded in the plastic material of the pre-injection package 202. All electrical conductors 118 are then held in their prescribed positions by the connecting tabs during embedding. After embedding, the connecting tabs are cut to electrically isolate the electrical conductors 118 from each other. The separation can be achieved, for example, mechanically by a separating tool or thermally by targeted energization. The recesses in the pre-injection package 202 that may exist due to the separation are then filled with the plastic material of the separating wall.

[0046] In one exemplary embodiment, the electrical conductor 118 is at least partially configured as a positive temperature coefficient resistor 204. At least a subsection of the electrical conductor 118 is composed of a material whose electrical resistance increases disproportionately with rising temperature. Because the current flowing through the positive temperature coefficient resistor 204 heats up and thus increases its resistance, which would reduce the current flow at the same voltage, the current flow through the electrical conductor 118 is automatically limited. Even at increased voltage, the current flow remains within a safe range.

[0047] Figure 3 The diagram shows an embedded electrical conductor 118 with a melt region 300 as a signal transmission element 108 of a control housing 100 according to an exemplary embodiment. The control housing 100 essentially corresponds to Figure 1 The controller housing in the embodiment. Here, the signal transmission element 108 is implemented as an electrical conductor 118. Figure 2 Unlike the conductors in FIG1 , conductor 118 has a constriction or bottleneck as a melting region 300. The conductor cross section of conductor 118 is significantly reduced in melting region 300 compared to the exposed connection region 120 and the other embedded regions. Melting region 300 has a higher electrical resistance than other regions of conductor 118 and heats up more intensely than other regions when the same current flows through signal transmission element 108. This is not a significant issue when low current flows for data transmission between controllers 102. However, if a malfunction, such as an overvoltage in one of controllers 102, causes a significantly increased current flow, melting region 300 heats up so intensely that it melts and interrupts the electrically conductive connection between controllers 102 before the other controllers 102 are damaged. Melting region 300 then acts as a fuse and blows open in the event of an overload, protecting the other controllers 102.

[0048] In one embodiment, the housing lower part 112 and the cover 114 are made of plastic material. In particular, the housing lower part 112 is made of the same plastic material as the partition wall 106. Thus, the housing lower part 112 and the partition wall 106 can be made in the same injection molding die.

[0049] Figure 4 1 shows an illustration of an embedded optical coupler 400 as a signal transmission element 108 of a controller housing 100 according to an exemplary embodiment. The controller housing essentially corresponds to Figure 1 The controller housing in the embodiment. Here, the signal transmission element 108 is implemented as a digital isolator 400. The digital isolator can be, for example, an optocoupler. Figure 2 Unlike the electrical conductors in the optical coupler 400, the optical coupler 400 is electrically isolated and electrically decouples the controller 102. The electrical connections of the optical coupler 400, or the connection region 120 of the optical coupler 400, extend into the two chambers 104 and are connected to the controller 102. The connection region 120 can be formed, for example, by at least one stamped grid on which the optical coupler 400 is arranged before the stamped grid and the optical coupler 400 are embedded in the plastic material of the partition wall 106.

[0050] Figure 5 FIG. 1 shows an illustration of an embedded inductive coupler 500 as a signal transmission element on a controller housing 100 according to an exemplary embodiment. The controller housing 100 essentially corresponds to Figure 1 104 . Signal transmission element 108 is implemented as an inductive coupler 500 or an isolating transformer. The current paths of inductive coupler 500 are electrically isolated from one another. Thus, inductive coupler 500 electrically isolates controller 102. Electrical connections of inductive coupler 500 or connection region 120 of inductive coupler 500 extend into both chambers 104 and are connected to controller 102.

[0051] In one embodiment, the inductive coupler 500 is implemented as a stamped grid and inserted into a partition wall mold. Here, the windings 502 of the inductive coupler 500 are arranged close together and are surrounded by plastic material during insertion and are thus electrically isolated from each other.

[0052] The following summarizes again or presents possible design solutions of the present invention using slightly different wording.

[0053] A dual-chamber concept for a controller is described, which has electrical isolation of printed circuit boards within the dual-chamber controller.

[0054] Control units (Electronic Control Units—ECUs) for automotive applications are subject to the requirement to prevent liquid media from entering the interior of the control unit, in order to prevent short circuits of electronic components, in particular.

[0055] The requirements for redundancy in, for example, steering / brake controllers require, depending on the application, that the electronics be divided into at least two subsystems. In the event of a failure in a subsystem, the second subsystem temporarily assumes the functionality of the controller.

[0056] The subsystems can be separated, for example, purely on the basis of electrical circuitry, that is, they are located in a common housing that is sealed against the surrounding environment. Therefore, if a medium enters, there is a risk that both subsystems could fail within a short period of time.

[0057] To reduce this risk, the two subsystems can be separated into chambers that are sealed from each other and from the surrounding environment. This requires a data connection between the two subsystems while adhering to sealing requirements. For example, this could involve using two controllers that are connected to each other via a cable plug system.

[0058] The two subsystems exchange electrical signals. Components such as isolators, optocouplers, fuses, or trace fuses can be used at the interface between two redundant subsystems to prevent the propagation of faults (e.g., due to overvoltage). Isolators and optocouplers are characterized by electrical isolation, while fuses or trace fuses are considered non-galvanically isolated safety components. In addition to electrical isolation, the physical separation of the subsystems is also important for system performance.

[0059] Therefore, a dual-chamber concept for a controller is presented herein, comprising two electrical subsystems located in two sealed chambers. This reduces the risk of simultaneous failure of all subsystems, for example due to media ingress into the housing interior. This is achieved by dividing the subsystems into chambers that are sealed from each other and from the surrounding environment.

[0060] The electrical connection to the printed circuit board is achieved, for example, via a circuit board connector. Injection-coated press-fit pins are used, for example. Elements for electrically isolating the two subsystems can be provided on the printed circuit board. Alternatively, tracking fuses can be used on the printed circuit board to protect against overcurrent and overvoltage. Isolating elements or "tracing fuses" on both sides of the system provide protection against overcurrent and overvoltage. Even if the chamber is completely flooded, the dual design of the fuse ensures protection.

[0061] The solution presented here enables the integration of isolator elements for separating subsystems into circuit board connectors.

[0062] Isolators (electronic components) can, for example, be arranged on a stamped grid and then injection-coated. Similarly, couplers (transformers) can be formed from a stamped grid and then injection-coated. In this embodiment, the stamped grid is designed so that no conductive connections occur between the chambers. In other words, the stamped grid is designed so that inductive or optical coupling occurs between the conductor loops of the stamped grid. Electrically, this creates a transformer that can conduct signals or even current without the risk of overvoltage on one side damaging the other.

[0063] Alternatively, a "tracing fuse" can be made of copper and injection-coated. Here, a narrow area is formed in the stamped grid that heats up and melts in the event of an overcurrent, thereby interrupting the current flow. The tracking fuses on both printed circuit boards can be omitted and replaced by a single injection-coated tracking fuse.

[0064] It is also possible to integrate a PTC or a metal with PTC properties into the partition wall. Here, a region made entirely or partially of a PTC material (PTC, positive temperature coefficient) is implemented on the stamped grid. This material increases its resistance at high currents and thus limits the current flow.

[0065] The PTC material can be selected to be very similar to copper in terms of its mechanical properties, thereby enabling the material to be processed within existing processes.

[0066] Compared to two independent, redundant controllers, the solution presented here allows the number of components to be kept low (housing, cover, etc.), requires less structural space, simplifies assembly, and allows the electrical connection of the printed circuit board to be achieved "internally", without the need for plugs / cables and without the need for sealed interfaces relative to the surrounding environment.

[0067] Compared to a controller having two subsystems but no media-tight separation, the risk of malfunction of the two subsystems due to medium ingress within a short period of time can be reduced.

[0068] A controller is described, comprising two chambers (separated in a media-tight manner) and a circuit board connector for electrically connecting subsystems. A plastic housing with a plug is divided into two chambers by a separating wall. At least one printed circuit board is located in each chamber. The housing cover has a corresponding mating contour for the housing to seal the two chambers from each other and from the surrounding environment. The electrical connection between the two subsystems is achieved via the circuit board connector. This circuit board connector, for example, consists of injection-coated press-fit pins. These pins can be directly injection-coated in the housing or, in larger quantities, can be pre-molded.

[0069] The sealing system can also be designed as a flat adhesive bond or an elastomer insert seal, each with an additional securing element for the cover. The housing cover can be made of various materials (die casting, deep drawing, plastic). The housing can also be made of metal. The plug and the separating wall are designed as plastic parts that are fastened and sealed to the housing from the inside or outside. In the case of lateral plug outlets, the separating wall is designed as an additional plastic part that ensures the separation of the two chambers and the electrical connection to the printed circuit board.

[0070] Finally, it is pointed out that terms such as "having", "comprising", etc. do not exclude other elements or steps, and terms such as "a" or "an" do not exclude a plurality. Reference signs in the claims are not to be considered as limitations.
