Description

Die Erfindung bezieht sich auf eine Türsteuerung gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a door control according to the preamble of claim 1.

In öffentlichen Verkehrsmitteln, die der Personenbeförderung dienen, wie z. B. in Omnibussen, werden Türbetätigungsanlagen eingesetzt, die ein Einklemmen von Personen oder Gegenständen während der Öffnungs- oder Schließphase einer Fahrzeugtür verhindern.In public transport that serve to transport people, such as B. in buses, door control systems are used to prevent jamming of people or objects during the opening or closing phase of a vehicle door.

Derartige Türsteuerungen werden z. B. elektropneumatisch betätigt, d.h. der Fahrer löst zum Öffnen oder Schließen der Tür einen elektrischen Impuls aus, der über eine elektronische Steuerung ein Türventil ansteuert. Dieses beaufschlagt einen als Türzylinder ausgebildeten Türanantrieb mit Druckluft, wobei die Hubbewegung des Türzylinderkolbens die Öffnungs- und Schließbewegungen der Tür auslösen.Such door controls are such. B. electropneumatically operated, i.e. the driver triggers an electrical impulse to open or close the door, which controls a door valve via an electronic control. This applies compressed air to a door drive designed as a door cylinder, the lifting movement of the door cylinder piston triggering the opening and closing movements of the door.

Eine solche Türsteuerung ist aus der DE-A 3 319 855 bekannt. Hier werden zur Überwachung der Öffnungs- und Schließbewegung von pneumatisch angetriebenen Türen pneumatische Differenzdruckschalter mit elektrischen Schaltkontakten eingesetzt, die bei Einklemmen einer Person oder eines Gegenstandes während der Öffnungs- oder Schließphase der Tür in Verbindung mit einer elektronischen Steuerung die Tür in einen für den Fahrgast ungefährlichen Zustand schalten. Dabei wird die Tür entweder reversiert oder der Türzylinder drucklos gemacht. Die Steuerung enthält einen Mikrocomputer (µC).Such a door control is known from DE-A 3 319 855. To monitor the opening and closing movement of pneumatically driven doors, pneumatic differential pressure switches with electrical switch contacts are used which, when a person or an object is trapped during the opening or closing phase of the door in conjunction with an electronic control, the door into a safe area for the passenger Switch state. The door is either reversed or the door cylinder is depressurized. The control contains a microcomputer (µC).

Es hat sich nun bei derartigen Anlagen als nachteilig herausgestellt, daß eine Überwachung des Türlaufs in Öffnungs- oder Schließrichtung nur solange erfolgen kann, wie die elektronische Steuerung mit Betriebsspannung versorgt wird. Da das in der Türsteuerung eingesetzte Türventil zur Umsteuerung des Türantriebs in Öffnungs-oder Schließrichtung lediglich mit einem Steuerimpuls definierter, kurzer Länge angesteuert werden muß, wird eine einmal eingeleitete Türbewegung auch bei während des Türlaufs abgeschalteter Betriebsspannung der elektronischen Steuerung fortgesetzt. Ein Abschalten der Betriebsspannung der Steuerung kann aber durch Ausschalten der Fahrzeugzündung zu jedem beliebigen Zeitpunkt erfolgen. Da in einem solchen Fall die oben beschriebene Überwachung des Türlaufs aufhört, kann sich eine gefährliche Situation ergeben, wenn z. B. eine Person in der sich schließenden Tür eingeklemmt wird.It has now been found to be disadvantageous in systems of this type that the door run can only be monitored in the opening or closing direction as long as the electronic control is supplied with operating voltage. Since the door valve used in the door control for reversing the door drive in the opening or closing direction only has to be controlled with a control pulse of a defined, short length, a door movement which has been initiated is continued even when the operating voltage of the electronic control is switched off during the door operation. However, the operating voltage of the control can be switched off at any time by switching off the vehicle ignition. Since the monitoring of the door movement described above stops in such a case, a dangerous situation can arise if e.g. B. a person is trapped in the closing door.

Außerhalb von Omnibussen befindet sich ein versteckt angebrachter Außentaster, mit dem z. B. bei einem auf dem Betriebshof abgestellten Fahrzeug ein Öffnen oder Schließen der beim Fahrersitz befindlichen vorderen Fahrzeugtür ohne Einschalten der Fahrzeugzündung ermöglicht wird. Hierbei wird mit dem Außentaster eine direkte Verbindung zwischen dem Türventil und der Fahrzeugbatterie hergestellt. Auch eine so von außen eingeleitete Türbewegung ist nicht überwacht, da die elektronische Steuerung ohne Spannungsversorgung ist.Outside of buses there is a hidden external push button with which e.g. B. in a parked on the yard opening or closing the driver's seat front vehicle door is enabled without turning on the vehicle ignition. In this case, a direct connection is established between the door valve and the vehicle battery using the external button. Even such a door movement initiated from the outside is not monitored, since the electronic control has no power supply.

Die hier aufgeführten Nachteile ließen sich durch einen Dauerbetrieb der Steuerelektronik umgehen. Ein dauernder Betrieb derartiger Steuerungen mit festem Anschluß an die Betriebsspannung ist jedoch nach geltenden Richtlinien nicht zulässig.The disadvantages listed here can be avoided by continuous operation of the control electronics. However, continuous operation of such controls with a fixed connection to the operating voltage is not permitted according to the applicable guidelines.

Der Erfindung liegt die Aufgabe zugrunde, die oben beschriebenen Nachteile elektropneumatischer Türsteuerungen zu beseitigen und eine Überwachung des Türlaufs auch nach Abschaltung der Zündspannung zu ermöglichen.The invention has for its object to eliminate the disadvantages of electropneumatic door controls described above and to enable monitoring of the door movement even after switching off the ignition voltage.

Diese Aufgabe wird durch die im Patentanspruch 1 enthaltene Erfindung gelöst. Die Unteransprüche enthalten zweckmäßige Weiterbildungen der Erfindung.This object is achieved by the invention contained in claim 1. The dependent claims contain expedient developments of the invention.

Die Erfindung wird im folgenden anhand einer Zeichnung näher erläutert. Diese zeigt ein vereinfachtes elektrisches Blockschaltbild der Türsteuerung.The invention is explained below with reference to a drawing. This shows a simplified electrical block diagram of the door control.

Alle elektronischen Bauteile der Türsteuerung sind in einer Elektronik 18 zusammengefaßt. Das Kernstück der elektronischen Türsteuerung ist ein Mikrocomputer (IlC) 1. Dieser steuert über einen Ausgang 20 ein Türventil 17 an in Abhängigkeit von Signalen eines Fahrertasters 10 sowie (nicht dargestellter) Reversier-Schalter. Als Mikrocomputer kann hier z. B. der Typ 8049 der Fa. Intel eingesetzt werden.All electronic components of the door control are combined in electronics 18. The core of the electronic door control is a microcomputer ( I lC) 1. This controls a door valve 17 via an output 20 as a function of signals from a driver button 10 and a reversing switch (not shown). As a microcomputer z. B. the type 8049 from Intel.

Im weiteren enthält die Steuerung einen Spannungswandler 2. Dieser wandelt die Bordnetz-Spannung von 24 V, die von einer Batterie 27 geliefert wird, in die Versorgungsspannung des Mikrocomputers von 5 V um. Der Eingang des Spannungswandlers 2 ist durch eine Zenerdiode 16 geschützt. Der Ausgang des Spannungswandlers 2 ist an den Versorgungsanschluß 22 des Mikrocomputers 1 angeschlossen. Über einen weiteren Ausgang 4 steuert der Mikrocomputer 1 ein Versorgungsrelais 5 an. Zwischen den Mikrocomputer 1 und das Versorgungsrelais 5 ist eine Leistungsendstufe 3 geschaltet, die über Dioden 15, 7 und 13 mit Betriebsspannung versorgt wird. Die Leistungsendstufe 3 ist vom Mikrocomputer 1 über eine Leitung 21 ansteuerbar.Furthermore, the control contains a voltage converter 2. This converts the on-board electrical system voltage of 24 V, which is supplied by a battery 27, into the supply voltage of the microcomputer of 5 V. The input of the voltage converter 2 is protected by a Zener diode 16. The output of the voltage converter 2 is connected to the supply connection 22 of the microcomputer 1. The microcomputer 1 controls a supply relay 5 via a further output 4. A power output stage 3 is connected between the microcomputer 1 and the supply relay 5 and is supplied with operating voltage via diodes 15, 7 and 13. The power output stage 3 can be controlled by the microcomputer 1 via a line 21.

Ein Kontakt 19 des Versorgungsrelais 5 ist über einen Eingang 6 der Elektronik 18 und eine Diode 7 mit dem Spannungswandler 2 verbunden. Der zweite Kontakt des Versorgungsrelais 5 ist über eine Leitung 24 mit der Fahrzeugbatterie 27 (Dauerplus) verbunden.A contact 19 of the supply relay 5 is connected to the voltage converter 2 via an input 6 of the electronics 18 and a diode 7. The second contact of the supply relay 5 is connected via a line 24 to the vehicle battery 27 (permanent plus).

Über je einen Eingang 8 und 9 sowie Signalleitungen 26, 25 ist der Mikrocomputer 1 mit dem Fahrertaster 10 und einem Außentaster 11 verbunden. Ein weiterer Eingang 12 und die Diode 13 verbindet den Eingang des Spannungswandlers 2 mit dem Pluspotential des Bordnetzes über den Zündschalter 23 (Batteriehauptschlater). Über eine interne Signalleitung 14 ist auch der Mikrocomputer 1 mit diesem Spannungspotential verbunden.The microcomputer 1 is connected to the driver button 10 and an outside button 11 via an input 8 and 9 as well as signal lines 26, 25. A further input 12 and the diode 13 connect the input of the voltage converter 2 to the plus potential of the vehicle electrical system via the ignition switch 23 (battery main switch). The microcomputer 1 is also connected via an internal signal line 14 connected to this voltage potential.

Der Fahrertaster 10 und der Außentaster 11 können auch als Steuerschalter ausgebildet sein, mit denen ein entsprechendes Relais angesteuert wird.The driver button 10 and the outside button 11 can also be designed as control switches with which a corresponding relay is controlled.

Das Versorgungsrelais 5 kann auch als elektronischer Schalter ausgebildet sein.The supply relay 5 can also be designed as an electronic switch.

Die Batterie 27 kann auch eine von mehreren Batterien sein, die z. B. nur zur Versorgung der Türelektronik dient.The battery 27 can also be one of several batteries which, for. B. only serves to supply the door electronics.

Im folgenden wird die Funktion der Steuerung beschrieben.The function of the controller is described below.

Im Normalbetrieb wird nach Einschalten der Fahrzeugzündung mit dem Zündschalter 23 der Mikrocomputer 1 über den Eingang 12 der Elektronik 18, die Diode 13 und den Spannungswandler 2 mit Betriebsspannung versorgt. Über die Leistungsendstufe 3 und den Kontakt 19 des Versorgungsrelais 5 schaltet dann der Mikrocomputer 1 das Pluspotential des Bordnetzes über den Eingang 6 und die Entkopplungsdiode 7 auf den Spannungswandler 2.In normal operation, after switching on the vehicle ignition with the ignition switch 23, the microcomputer 1 is supplied with operating voltage via the input 12 of the electronics 18, the diode 13 and the voltage converter 2. The microcomputer 1 then switches the plus potential of the vehicle electrical system via the input 6 and the decoupling diode 7 to the voltage converter 2 via the power output stage 3 and the contact 19 of the supply relay 5.

Wird der Fahrertaster 10 oder der Außentaster 11 betätigt, so erfolgt ein entsprechender Türlauf durch Ansteuerung des Türventils 17 in Öffnungs-oder Schließrichtung. Über die interne Verbindungsleitung 14 kann der Mikrocomputer 1 zu jedem Zeitpunkt die eingeschaltete Fahrzeugzündung überprüfen.If the driver button 10 or the outside button 11 is actuated, then the door runs accordingly by actuating the door valve 17 in the opening or closing direction. The microcomputer 1 can check the switched-on vehicle ignition at any time via the internal connecting line 14.

Wird während eines Türlaufs die Fahrzeugzündung mit dem Zündschalter 23 ausgeschaltet, so bleibt die Steuerung weiterhin über den Kontakt 19 des Versorgungsrelais 5 in Betrieb, da der Spannungswandler 2 über den Eingang 6 und die Entkopplungsdiode 7 weiterhin mit Dauerplus auf der Leitung 24 verbunden ist. Erst nachdem die Tür eine der Endlagen "auf" oder "zu" erreicht hat, was der Mikrocomputer 1 durch Signale von (nicht dargestellten) Endschaltern erkennt, oder nach einer vorbestimmten Zeit, schaltet sich die Steuerung bzw. der Mikrocomputer 1 durch Abschalten des Versorgungsrelais 5 selbständig aus.If the vehicle ignition is switched off with the ignition switch 23 during a door run, the control system remains in operation via the contact 19 of the supply relay 5, since the voltage converter 2 is still connected to the line 24 via input 6 and the decoupling diode 7. Only after the door has reached one of the end positions "open" or "closed", which the microcomputer 1 recognizes by signals from (not shown) limit switches, or after a predetermined time, does the control or the microcomputer 1 switch off by switching off the supply relay 5 independently.

Wird bei ausgeschalteter Fahrzeugzündung der Außentaster 11 betätigt, so wird die Elektronik 18 bzw. der Spannungswandler 2 über den Eingang 9 und die Entkopplungsdiode 15 mit Betriebsspannung versorgt. Über den Eingang 6, die Entkopplungsdiode 7 und den Kontakt 19 des Versorgungsrelais 5 verbindet der Mikrocomputer 1 wiederum den Spannungswandler 2 mit der Leitung 24, so daß dann der Spannungswandler 2 und damit der Mikrocomputer 1 auch nach dem Loslassen des Außentasters 11 mit der erforderlichen Betriebsspannung versorgt sind.If the external button 11 is actuated when the vehicle ignition is switched off, the electronics 18 or the voltage converter 2 are supplied with operating voltage via the input 9 and the decoupling diode 15. Via the input 6, the decoupling diode 7 and the contact 19 of the supply relay 5, the microcomputer 1 in turn connects the voltage converter 2 to the line 24, so that the voltage converter 2 and thus the microcomputer 1 with the required operating voltage even after the external pushbutton 11 has been released are supplied.

Über die Verbindung vom Eingang 9 zum Mikrocomputer 1 wird in diesem Fall die Betätigung des Außentasters 11 erkannt und eine entsprechende Türbewegung eingeleitet. Am Ende dieser Türbewegung überprüft der Mikrocomputer 1 über den Eingang 12 und die Verbindungsleitung 14, ob zwischenzeitlich die Fahrzeugzündung eingeschaltet wurde. Ist dies nicht der Fall, und wird der Außentaster 11 nicht mehr betätigt, so wird das Versorgungsrelais 5 und somit die Elektronik 18 über den Mikrocomputer 1 selbsttätig ausgeschaltet. Die Ausschaltung kann auch nach Ablauf einer festen Verzögerungszeit nach Betätigung des Außentasters 11 erfolgen.In this case, the actuation of the external button 11 is recognized via the connection from the input 9 to the microcomputer 1 and a corresponding door movement is initiated. At the end of this door movement, the microcomputer 1 checks via the input 12 and the connecting line 14 whether the vehicle ignition has been switched on in the meantime. If this is not the case and the external button 11 is no longer actuated, the supply relay 5 and thus the electronics 18 are automatically switched off via the microcomputer 1. The switch-off can also take place after a fixed delay time after actuation of the external button 11.

Zur Vereinfachung des Schaltbildes wurden Spannungspegelanpasser, die für die Funktion nicht von Bedeutung sind, weggelassen.To simplify the circuit diagram, voltage level adjusters that are not important for the function have been omitted.
