Abstract

The invention relates to a starting device for internal combustion engines, comprising a starter motor having a pinion which initially engages the toothed ring of the internal combustion engine with a starting signal through an engaging magnet, before the starter motor triggers with full power the starting process. The aim of the invention is to improve engagement of the starter pinion and switching of the starter motor. For this purpose, the starter motor (SM) first drives the starter pinion with a reduced torque by means of the starting signal (st) through a series resistor (Rvor), and the engaging magnet (EM) engages the pinion with the toothed ring of the internal combustion motor. The engaging magnet (EM) then depresses fully the pinion in the toothed ring of the internal combustion engine, and the starter motor (SM) starts the internal combustion engine with full torque through by-passing the series resistor (Rvor).

Andrehvorrichtunq für BrennkraftmaschinenStarting device for internal combustion engines
Stand der TechnikState of the art
Die Erfindung betrifft eine Andrehvorrichtung für Brennkraftmaschinen mit einem Startermotor, dessen Starterritzel zunächst mit einem Anlaßsignal über einen Einrückmagneten in den Zahnkranz der Brennkraftmaschine einspurt, bevor der Startermotor mit voller Kraft den Andrehvorgang auslöst.The invention relates to a starting device for internal combustion engines with a starter motor, the starter pinion of which initially engages with a starting signal via an engagement magnet in the ring gear of the internal combustion engine before the starter motor triggers the starting process with full force.
Eine Andrehvorrichtung dieser Art ist aus der DE 30 02 232 C2 bekannt. Bei dieser bekannten Andrehvorrichtung wird mit dem Kontakt des Zündschlosses der Einrückmagnet voll angesteuert, so dass das Starterritzel mit voller Kraft gegen den Zahnkranz der Brennkraftmaschine anschlägt, wenn es nicht direkt ein- gespurt werden kann. Dies führt zu Abnutzungserscheinungen oder Beschädigung der Verzahnungen der beiden aufeinanderstoßenden Teile. Außerdem steuert der Einrückmagnet eine Kontaktbrücke, die den Startermotor einschaltet. Der Schaltvorgang dieser Kontaktbrücke ist bei dieser Steuerung nicht störungsfrei. Es ist Aufgabe der Erfindung, eine Andrehvorrichtung der eingangs erwähnten Art so zu verbessern, dass das Einspuren des Starterritzels in den Zahnkranz derA starting device of this type is known from DE 30 02 232 C2. In this known starting device, the engagement magnet is fully actuated with the contact of the ignition lock, so that the starter pinion strikes with full force against the ring gear of the internal combustion engine if it cannot be engaged directly. This leads to signs of wear or damage to the teeth of the two abutting parts. In addition, the engagement magnet controls a contact bridge that switches on the starter motor. The switching process of this contact bridge is not trouble-free with this control. It is an object of the invention to improve a starting device of the type mentioned at the outset in such a way that the starter pinion is engaged in the ring gear
Brennkraftmaschine und das Schalten des Startermotors verbessert werden.Internal combustion engine and the switching of the starter motor can be improved.
Diese Aufgabe wird nach der Erfindung dadurch gelöst, dass der Startermotor mit dem Anlaßsignal zunächst über einen Vorwiderstand mit reduziertem Dreh- moment das Starterritzel antreibt und der Einrückmagnet das Ritzel bis in denThis object is achieved according to the invention in that the starter motor first drives the starter pinion with the starting signal via a series resistor with reduced torque and the engagement magnet drives the pinion into the
Zahnkranz der Brennkraftmaschine einspurt und dass danach der Einrückmagnet das Starterritzel vollständig in den Zahnkranz der Brennkraftmaschine eindrückt und der Startermotor durch Überbrückung des Vorwiderstandes mit vollem Drehmoment die Brennkraftmaschine durchdreht.Engages the ring gear of the internal combustion engine and that the engaging magnet then presses the starter pinion fully into the ring gear of the internal combustion engine and the starter motor rotates the internal combustion engine by bridging the series resistor with full torque.
Für das Einspuren des Starterritzels ergibt sich dadurch ein zweistufiger Ablauf. In der ersten Stufe wird der Startermotor über den Vorwiderstand mit geringem Drehmoment betrieben. Das Verdrehen des Startermotors erleichtert das Finden einer Zahnlücke und mit dem Vorschub des Starterritzels wird der Verschleiß beim Auftreffen des Starterritzels auf den Zahnkranz der Brennkraftmaschine verringert, insbesondere dann, wenn durch begrenzte Bestromung des Relais ein sanftes Vorspuren vorgenommen wird. In der zweiten Stufe wird der Einrückmagnet voll bestromt, so dass das Starterritzel vollständig in den Zahnkranz der Brennkraftmaschine einrücken kann. Danach wird der Startermotor voll bestromt und dreht mit vollem Drehmoment.This results in a two-stage process for engaging the starter pinion. In the first stage, the starter motor is operated with low torque via the series resistor. The rotation of the starter motor makes it easier to find a tooth gap and with the advance of the starter pinion, wear is reduced when the starter pinion strikes the ring gear of the internal combustion engine, especially if a gentle toe-in is carried out due to limited current supply to the relay. In the second stage, the engagement magnet is fully energized so that the starter pinion can fully engage in the ring gear of the internal combustion engine. Then the starter motor is fully energized and turns at full torque.
Nach einer Ausgestaltung ist vorgesehen, dass das Anlaßsignal einer Logikschaltung zugeführt ist, die über einen ersten angesteuerten Halbleiter, z.B. einen Highside-Smart-FET die Reihenschaltung aus Vorwiderstand und Starter- motor mit reduziertem Strom beaufschlagt und dass die Logikschaltung über einen zweiten angesteuerten Halbleiter, z.B. einen zweiten Highside-Smart-FET den Einrückmagneten getaktet ansteuert, bis das Starterritzel in den Zahnkranz der Brennkraftmaschine einspurt.According to one embodiment, it is provided that the starting signal is fed to a logic circuit, which applies a reduced current to the series circuit comprising a series resistor and starter motor via a first controlled semiconductor, for example a highside smart FET, and that the logic circuit via actuates a second controlled semiconductor, for example a second highside smart FET, in a clocked manner until the starter pinion engages in the ring gear of the internal combustion engine.
Bei dieser Ansteuerung wird der Anlaßkontakt des Zündschlosses entlastet und mit Ansteuerung der beiden Highside-Smart-FETs kann zudem eine zeitliche Ab- -folge eingeführt werden, so dass die reduzierte Ansteuerung des Startermotors zeitgleich mit dem Beaufschlagen des Einrückmagπeten erfolgen kann oder der Einrückmagnet auch erst nach dem Anlaufen des Startermotors beaufschlagt werden kann.With this control, the starter contact of the ignition lock is relieved and, with the control of the two highside smart FETs, a chronological sequence can also be introduced, so that the reduced control of the starter motor can take place simultaneously with the application of the engagement magnet or the engagement magnet also first can be applied after starting the starter motor.
Mit der getakteten Ansteuerung des Einrückmagneten wird der Strom reduziert und damit die thermische Belastung. Außerdem wird dadurch ein sanftes Einspuren des Starterritzels in den Zahnkranz der Brennkraftmaschine erreicht.With the clocked activation of the engagement magnet, the current is reduced and thus the thermal load. In addition, this gently engages the starter pinion in the ring gear of the internal combustion engine.
Eine zeitliche Zwangsfolge der beiden Schaltvorgänge läßt sich auch dadurch er- reichen, dass der zweite Halbleiter mit dem ersten Halbleiter in Reihe geschaltet ist und dass nach dem Einspuren des Starterritzels der zweite Halbleiter über die Logikschaltung voll durchgesteuert ist.A forced sequence of the two switching processes can also be achieved in that the second semiconductor is connected in series with the first semiconductor and that after the starter pinion has been engaged, the second semiconductor is fully controlled via the logic circuit.
Der Übergang der beiden Stufen des Einspurens und Schalten des Startermotors kann nach einer Ausgestaltung dadurch gesteuert erfolgen, dass das Einspuren des Starterritzels in den Zahnkranz der Brennkraftmaschine mittels eines Wegesensors überwacht und der Logikschaltung angezeigt wird und dass die Logikschaltung in Abhängigkeit von dem Ansprechen des Wegesensors den zweiten Halbleiter vom getakteten Betrieb auf Dauerbetrieb umschaltet. Die Einleitung der zweiten Stufe des Andrehvorganges wird dadurch bewirkt, dass nach dem Eindrücken des Starterritzels in den Zahnkranz der Brennkraftmaschine die Logikschaltung einen dritten Halbleiter, z.B. einen dritten Highside- Smart-FET ansteuert, der ein Leistungsrelais einschaltet und dass ein Kontakt des Leistungsrelais den Startermotor mit vollem Strom beaufschlagt, wobei der dritte Halbleiter z.B. an dem Pluspotential der Versorgungsspannung angeschal- tet und mit dem an Masse angeschalteten Leistungsrelais oder umgekehrt in Reihe geschaltet ist. Mit der Einbeziehung eines Leistungsrelais kann die vom Einrückmagnet gesteuerte Kontaktbrücke entfallen. Der elektrische Steuerungsteil für die zweite Stufe des Einspurens und Schalten des Startermotors kann nach einer weiteren Ausgestaltung auch so vorgenommen werden, dass nach dem Eindrücken des Starterritzels in den Zahnkranz der Brennkraftmaschine dieAccording to one embodiment, the transition from the two stages of engagement and switching of the starter motor can be controlled in such a way that the engagement of the starter pinion in the ring gear of the internal combustion engine is monitored by means of a displacement sensor and is displayed to the logic circuit, and that the logic circuit is dependent on the response of the displacement sensor second semiconductor switches from clocked operation to continuous operation. The initiation of the second stage of the starting process is brought about by the fact that after the starter pinion is pressed into the ring gear of the internal combustion engine, the logic circuit controls a third semiconductor, for example a third highside smart FET, which switches on a power relay and that a contact of the power relay drives the starter motor charged with full current, the third semiconductor being connected, for example, to the plus potential of the supply voltage and being connected in series with the power relay connected to ground or vice versa. With the inclusion of a power relay, the contact bridge controlled by the engagement magnet can be omitted. According to a further embodiment, the electrical control part for the second stage of engagement and switching of the starter motor can also be carried out in such a way that after the starter pinion is pressed into the ring gear of the internal combustion engine
Logikschaltung einen N-Kanal-MOS-FET ansteuert, der das Leistungsrelais einschaltet und dass ein Kontakt des Leistungsrelais den Startermotor mit vollem Strom beaufschlagt, wobei das Leistungsrelais an dem Pluspotential der Ver- sorgungsspanπung angeschaltet und der an Masse angeschaltete N-Kanal-MOS- FET mit dem Leistungsrelais (LR) in Reihe geschaltet ist.Logic circuit controls an N-channel MOS-FET, which switches on the power relay and that a contact of the power relay applies full current to the starter motor, the power relay being connected to the plus potential of the supply voltage and the N-channel MOS- FET is connected in series with the power relay (LR).
Ist nach einer Ausgestaltung vorgesehen, dass die Logikschaltung nach einer vorgegebenen Zeit vom getakteten Betrieb auf Dauerbetrieb für den Einrückmagneten umschaltet, dann übernimmt die Logik die reine Funktion einer Ablauf- Steuerung ohne Rückmeldung. Dabei wird vorausgesetzt, dass das Starterritzel immer eine Zahnlücke gefunden hat, d.h. eingespurt ist. Mit der erfindungsgemäßen Andrehrichtung kann der Aufbau so vorgenommen werden, dass der Startermotor, der Einrückmagnet und gegebenenfalls der Wegesensor eine von Elektronikteil mit der Logikschaltung, dem Vorwiderstand den Highside-Smart- FETs bzw. dem N-Kanal-MOS-FET und dem Leistungsrelais getrennte Starter- einheit bildet, die über drei Leitungen mit dem Elektronikteil verbunden ist.If it is provided according to one embodiment that the logic circuit switches from clocked operation to continuous operation for the engagement magnet after a predetermined time, then the logic takes over the pure function of a sequence control without feedback. It is assumed that the starter pinion has always found a tooth gap, ie is engaged. With the starting direction according to the invention, the construction can be carried out in such a way that the starter motor, the engagement magnet and, if applicable, the displacement sensor are one of the electronic part with the logic circuit, the series resistor the highside smart FETs or the N-channel MOS-FET and the power relay forms a separate starter unit which is connected to the electronic part via three lines.
Der Elektronikteil kann vom Starter getrennt sein und direkt in der Nähe der Batterie plaziert werden. Dadurch läßt sich die Länge der in der Regel nicht abgesicherten Leitung (Kl. 30) auf ein Minimum reduzieren. Der Starter ist - außerhalb des eigentlichen Startvorganges spannungslos, so dass nur geringeThe electronic part can be separated from the starter and placed directly near the battery. As a result, the length of the line (terminal 30), which is generally not fused, can be reduced to a minimum. The starter is without voltage outside of the actual starting process, so that only a small amount
Kurzschluß- und Brandgefahr besteht. Außerdem sind die Umweltbedingungen (Temperaturbelastung, Schwingungsbeschleunigung, Dichtheit usw.) für den Elektronikteil an diesem Anbauort weniger kritisch als direkt am Starter, wie bei bekannten Andrehvorrichtungen. Der Einrückmagnet ist einfacher, da er keine Kontaktbrücke steuern muß. Dies hat einen Platz- und Kostenvorteil und bietet zudem die Möglichkeit, den Starter als Koaxialstarter auszuführen.There is a risk of short circuit and fire. In addition, the environmental conditions (temperature load, vibration acceleration, tightness, etc.) are less critical for the electronic part at this mounting location than directly at the starter, as is the case with known starting devices. The engagement magnet is simpler because it does not have to control a contact bridge. This has a space and cost advantage and also offers the possibility of designing the starter as a coaxial starter.
Die Andrehvorrichtung bringt auch eine vereinfachte Anschlußtechnik am Starter, der nur die Klemmen 50 und 45 sowie evt. einen Anschluß für den Wegsen- sor WS benötigt. Am Starter sind auch keine internen Verbindungen nötig. DieThe starter also brings a simplified connection technology to the starter, which only requires terminals 50 and 45 and possibly a connection for the WS travel sensor. No internal connections are required on the starter. The

Die Erfindung wird anhand von zwei in der Zeichnung als Stromlaufplane dargestellten Ausführungsbeispielen näher erläutert. Es zeigen:The invention is explained in more detail with reference to two exemplary embodiments shown in the drawing as circuit diagrams. Show it:
Fig. 1 ein erstes Ausführungsbeispiel einer Andrehvorrichtung mit einem über einen Highside-Smart FET geschalteten Leistungsrelais und Fig. 2 ein zweites Ausführungsbeispiel einer Andrehvorrichtung mit einem über einen N-Kanal-MOS-FET gesteuerten Leistungsrelais.Fig. 1 shows a first embodiment of a starting device with a power relay connected via a highside smart FET and Fig. 2 shows a second embodiment of a starting device with a power relay controlled via an N-channel MOS-FET.
Das von dem Kontakt des Zündschlosses in einem Kraftfahrzeug abgegebene Anlaßsignal wird bei der erfindungsgemäßen Andrehvorrichtung einer Logik- schaltung L zugeführt, wie mit st an der Klemme 50e gezeigt ist. Die Logikschaltung L gibt für die Dauer des Anstehens des Anlaßsignals st ein Steuersignal auf den Ausgang a1 , das den Highside-Smart-FET T1 leitend steuert, der an dem Pluspotential (Klemme 30) der Versorgungsspannung U angeschaltet ist. Damit wird über eine Reihenschaltung aus dem Vorwiderstand Rvor und dem Startermotor SM mit reduziertem Strom beaufschlagt, so dass der Startermotor mit reduziertem Drehmoment das Starterritzel antreibt. Gleichzeitig oder zeitlich verzögert steuert die Logikschaltung L den Ausgang a2 an und zwar getaktet. Die Taktimpulse beaufschlagen über den Highside-Smart-FET T2 den nachgeschalteten Einrückmagneten EM. Dies setzt in der gezeigten Reihenschaltung die Durchschaltung des Highside-Smart-FET T1 und damit ein Drehen des Startermotors SM voraus. Der Einrückmagnet EM wird auf diese Weise sanft, d.h. mit reduziertem Strombedarf verstellt, was zu einem sanften Vorspuren und Einspuren mit reduziertem Drehmoment des Starterritzels in den Zahnkranz der Brennkraftmaschine führt. Das Einspuren kann mittels eines Wegsensors WS, z.B. einem Endschalter überwacht werden. Ist das Starterritzel in den Zahnkranz der Brennkraftmaschine eingespurt, dann gibt der Wegsensor WS auf den Eingang e1 der Logikschaltung L ein Anzeigesignal, das zu einem Steuersignal auf dem Ausgang a3 führt. Der Highside-Smart-FET T3 wird leitend gesteuert und schaltet das Leistungsrelais LR ein, das mit seinem Kontakt t den Startermotor SM direkt mit dem Pluspotential der Versorgungsspannung U verbindet und somit den Vorwiderstand R vor und den FET T1 überbrückt. Der Startermotor 7The starting signal emitted by the contact of the ignition lock in a motor vehicle is fed to a logic circuit L in the starter device according to the invention, as shown by st at terminal 50e. The logic circuit L gives a control signal to the output a1 for the duration of the start signal st, which controls the highside smart FET T1 which is connected to the plus potential (terminal 30) of the supply voltage U. A series connection of the series resistor Rvor and the starter motor SM thus applies a reduced current, so that the starter motor drives the starter pinion with reduced torque. At the same time or with a time delay, the logic circuit L controls the output a2 and clocked. The clock pulses act on the downstream engagement magnet EM via the highside smart FET T2. In the series connection shown, this requires the highside smart FET T1 to be switched through and thus the starter motor SM to be turned. In this way, the engagement magnet EM is adjusted gently, ie with a reduced current requirement, which leads to a gentle toe-in and engagement with reduced torque of the starter pinion into the ring gear of the internal combustion engine. The engagement can be monitored by means of a distance sensor WS, for example a limit switch. If the starter pinion is engaged in the ring gear of the internal combustion engine, then the displacement sensor WS outputs an indication signal to the input e1 of the logic circuit L, which leads to a control signal at the output a3. The highside smart FET T3 is controlled in the on state and switches on the power relay LR, which connects the starter motor SM with its contact t directly to the plus potential of the supply voltage U and thus bridges the series resistor R before and bridges the FET T1. The starter motor 7
SM treibt über das Starterritzel nun den Zahnkranz der Brennkraftmaschine mit vollem Drehmoment an.SM now drives the internal gear ring gear at full torque via the starter pinion.
Der Wegsensor WS kann auch entfallen, wenn nach dem Einleiten des Einspu- rens über das Steuersignal auf den Ausgang a2 eine vorgegebene Zeit abgelaufen ist und die Logikschaltung L auf dem Ausgang a3 das Leistungsrelais LR einschaltet. Diese Zwangssteuerung setzt voraus, dass der Einspur- und Einrückvorgang in dieser Zeit erfolgreich durchgeführt wurde.The distance sensor WS can also be omitted if a predetermined time has elapsed after initiation of the intervention via the control signal to the output a2 and the logic circuit L switches on the power relay LR at the output a3. This forced control assumes that the engagement and engagement process has been carried out successfully during this time.
Wie die Fig. 1 zeigt, kann der Startermotor SM und der Einrückmagnet EM gegebenenfalls mit dem Wegsensor WS als Starter ST von Elektronikteil ET ge- trennt aufgebaut werden. Beide Teile sind dann über zwei bzw. drei Leitungen miteinander verbunden und erlauben unterschiedliche Einbauorte im Kraftfahrzeug, wie die Klemmen w, 50 und 45 zeigen.As shown in FIG. 1, the starter motor SM and the engagement magnet EM can optionally be constructed separately from the electronic part ET with the displacement sensor WS as the starter ST. Both parts are then connected to one another via two or three lines and allow different installation locations in the motor vehicle, as shown by the terminals w, 50 and 45.
Der Aufbau der Andrehvorrichtung nach Fig. 2 unterscheidet sich von der nach Fig. 1 nur durch den Stromkreis für das Leistungsrelais LD, das über einen kostengünstigeren N-Kanal-MOS-FET T4 eingeschaltet wird. Dieser N-Kanal-MOS- FET T4 ist mit dem Massepotential verbunden und mit dem am Pluspotential der Versorgungsspannung U angeschalteten Leistungsrelais LR in Reihe geschaltet. Die Ansteuerung erfolgt über den Ausgang a3 der Logikschaltung L mit dem richtigen Ansteuerpotential.The construction of the starter device according to FIG. 2 differs from that according to FIG. 1 only by the circuit for the power relay LD, which is switched on via a less expensive N-channel MOS-FET T4. This N-channel MOSFET T4 is connected to the ground potential and connected in series with the power relay LR connected to the plus potential of the supply voltage U. The control takes place via the output a3 of the logic circuit L with the correct control potential.
Bei der Schaltung nach Fig. 1 mit dem dritten Highside-Smart-FET T3 erfolgt die Ansteuerung über den Ausgang a3 und dem dafür erforderlichen anderen Ansteuerpotential. Der Highside-Smart-FET T3 ist am Pluspotential der Versor- 8In the circuit according to FIG. 1 with the third highside smart FET T3, the control takes place via the output a3 and the other control potential required for this.

Der Steuerungsablauf der beiden Andrehvorrichtungen nach Fig. 1 und 2 ist jedoch identisch. However, the control sequence of the two starting devices according to FIGS. 1 and 2 is identical.
