Description
Die Erfindung betrifft eine elektronische Kontrolleinheit für eine elektrohydraulische Druckregelvorrichtung gemäß Oberbegriff von Anspruch 1.The invention relates to an electronic control unit for an electrohydraulic pressure control device according to the preamble of claim 1.
Für elektronische Bremsysteme in Kraftfahrzeugen, insbesondere elektrohydrauliche Bremssysteme (EHB) werden besonders leistungsfähige elektronische Regler benötigt. Im Gegensatz zu herkömmlichen Bremsystemen, z. B. ABS, sind die Anforderungen erheblich höher. So befindet sich das System aus elektronischer Kontrolleinheit und hydraulischer Kontrolleinheit in höherem Maße im Zustand der Regelung, wodurch sich pro Zeiteinheit eine höhere lokale Wärmemenge aufgrund im Wesentlichen ohmscher Widerstände der Elektronik bzw. der Spulen einstellt. Diese entstehende Wärmemenge kann jedoch durch bestehende magnetische Stecker und Reglergehäuse aus Kunststoff nicht ausreichend abgeführt werden. Diese sind insofern nicht für EHB einsetzbar.For electronic brake systems in motor vehicles, especially electrohydraulic brake systems (EHB) particularly powerful electronic controllers are needed. In contrast to conventional brake systems, z. B. ABS, the requirements are considerably higher. Thus, the system of electronic control unit and hydraulic control unit is in a higher degree in the state of the control, whereby per unit of time sets a higher local heat quantity due to substantially ohmic resistances of the electronics or the coils. However, this resulting amount of heat can not be adequately dissipated by existing magnetic plug and controller housing made of plastic. These are not suitable for EHB.

Die vorliegende Erfindung setzt sich zum Ziel, eine elektronische Kontrolleinheit für elektrohydraulische Druckregelvorrichtungen zur Verfügung zu stellen, welche eine verbesserte Anpassung insbesondere gegenüber thermischen Ausdehnungseffekten sowie Bauteiltoleranzen aufweist.The present invention sets itself the goal of providing an electronic control unit for electrohydraulic pressure control devices which has an improved adaptation, in particular to thermal expansion effects and component tolerances.
Diese Aufgabe wird durch eine elektronische Kontrolleinheit gemäß Anspruch 1 gelöst.This object is achieved by an electronic control unit according to claim 1.
Vorteilhafterweise besteht die erfindungsgemäße elektronische Kontrolleinheit aus einem einfachen und kostengünstigen Alugehäuse. Das Alugehäuse gemäß der Erfindung ist günstig herstellbar, da es ganz ohne einen schieberintensiven Hinterschnitt auskommt.Advantageously, the electronic control unit according to the invention consists of a simple and inexpensive aluminum housing. The aluminum housing according to the invention is inexpensive to produce, since it does not require a slider-intensive undercut completely.
Die Leiterplatte, auf der sich im Allgemeinen die Reglerelektronik befindet, ist vorzugsweise so am Reglergehäuse angebracht, dass die Wärmeabfuhr besonders günstig ist.The printed circuit board, on which the controller electronics are generally located, is preferably mounted on the controller housing so that the heat dissipation is particularly favorable.
Die elektromagnetischen Spulen zur Betätigung der Hydraulikventile sind am Gehäuserahmen vorzugsweise solide in der Weise aufgehängt, dass einrastende Halteelemente vorgesehen sind, die insbesondere an den Ventilspulen befestigt sind und in Aussparungen am Gehäuserahmen einrasten. Dieses Design erfüllt besonders gut die gestellten Anforderungen bezüglich mechanischer, elektrischer und thermischer Anbindung bei ausreichend elastischer Aufhängung, welche notwendig ist, um fertigungstechnische Bauteiltoleranzen in X, Y und Z-Richtung auszugleichen.The electromagnetic coils for actuating the hydraulic valves are preferably solidly hung on the housing frame in such a way that latching holding elements are provided, which are fastened in particular to the valve coils and engage in recesses on the housing frame. This design is particularly well suited to the mechanical, electrical and thermal bonding requirements with sufficient elastic suspension, which is necessary to compensate for manufacturing component tolerances in the X, Y and Z directions.
Bevorzugt kann bei der erfindungsgemäßen elektronischen Kontrolleinheit auf die Verwendung von Gießmassen verzichtet werden. Vielfach werden Gießmassen zum Schutz der Elektronik vor Verschmutzung und Korrosion, als auch zur Verbesserung der Wärmeableitung eingesetzt. Dieses bekannte Verfahren ist jedoch kostenintensiv und führt zu einem aufwendigeren Herstellungsprozess.In the case of the electronic control unit according to the invention, the use of casting compounds may preferably be dispensed with. In many cases, casting compounds are used to protect the electronics from contamination and corrosion, as well as to improve heat dissipation. However, this known method is cost-intensive and leads to a more complex production process.
Gemäß vorliegender Erfindung werden größere Teile des Reglergehäuses aus einem wärmeleitenden Material, insbesondere Aluminium, besonders bevorzugt in Aluminiumspritzguss, gefertigt. Vorteilhafterweise kann bei Verwendung von Aluminium als Gehäusematerial eine einfachere Spulenaufhängung verwendet werden, als bei Reglern, die in an sich bekannter Weise in einem Kunststoffgehäuse angeordnet werden.According to the present invention, larger parts of the regulator housing are made of a thermally conductive material, in particular aluminum, particularly preferably in aluminum injection molding. Advantageously, when using aluminum as the housing material a simpler coil suspension can be used, as with regulators, which are arranged in a conventional manner in a plastic housing.
Bei Verwendung von wärmeleitendem Material lässt sich das Reglergehäuse vorteilhafterweise weniger aufwendig fertigen, als ein Kunststoffgehäuse, ohne das die wärmeleitenden Eigenschaften dabei verschlechter werden. Die erfindungsgemäße Konstruktion bietet zudem eine verbesserte Trennung von Spulenbereich zu Elektronikbereich. Die verbesserte Kopplung zwischen Verschlussmittel und Gehäuserahmen führt ebenfalls zu einer verbesserten Wärmeableitung.When using thermally conductive material, the controller housing can advantageously be less expensive finished, as a plastic housing, without the heat-conducting properties are deteriorated thereby. The construction according to the invention also offers an improved separation from coil region to electronics region. The improved coupling between the closure means and the housing frame also results in improved heat dissipation.
