Definitions

  • the invention relates to a starter for starting an internal combustion engine according to the preamble of patent claim 1.
  • Pinion starters include a DC motor with a pinion that engages a ring gear of the internal combustion engine and rotates the internal combustion engine at a start request.
  • the sprocket of the internal combustion engine is located i. d.
  • known pinion starters include a so-called engagement relay that attracts an engagement lever that latches the pinion into the ring gear of the internal combustion engine. As soon as the engagement relay has attracted, a main current path is automatically closed, which supplies the starter motor with electrical power. This will start the actual cranking process.
  • An essential aspect of the invention is to provide another switch parallel to the relay switch of the starter relay and to control this switch so that it is closed at least at the time in which the relay switch opens and / or closes.
  • the parallel switch virtually forms a bypass and serves to relieve the relay switch. Closing the bypass switch causes the voltage applied to the relay switch to be reduced, thus reducing the risk of relay firing. The life of the starter can thus be significantly extended.
  • the field strengths occurring at the contacts of the relay switch are particularly high when the relay switch opens. It is therefore proposed to keep the bypass switch closed at least at the time at which the relay switch opens. Preferably, the bypass switch is closed every time the relay switch changes state.
  • the bypass switch is closed shortly before a change in state of the relay switch and shortly thereafter reopened.
  • the voltage drop across the relay switch is reduced at least at the time of a switching operation.
  • the bypass switch is also closed during the entire period in which the relay switch is closed.
  • the current to supply the starter motor flows through both the main current path and the relay switch as well as the bypass path and the bypass switch to the starter motor.
  • the bypass switch is preferably connected to a supply potential, such as the battery voltage of the vehicle electrical system, and to the starter motor.
  • the bypass switch is preferably a transistor, in particular a MOS transistor.
  • the starter according to the invention is preferably a so-called pinion starter.
  • the invention can also be used.
  • FIG. 1 shows a starter for automotive internal combustion engines with a bypass switch.
  • Fig. 2a shows the switching state of the relay switch
  • Fig. 2b shows the switching state of the bypass switch.
  • Fig. 1 shows a schematic representation of a pinion starter for starting an internal combustion engine.
  • the pinion starter comprises a starter relay 1, by means of which a main current path 7 can be closed or opened to the starter motor 4.
  • the control line 8 of the starter relay 1 is energized, so that the relay 1 attracts.
  • an engagement lever 11 is actuated, which spins the pinion 5 in a ring gear 6 of the motor vehicle engine (not shown).
  • the relay switch 2 closes automatically, and the starter motor 4 is supplied with electric power. As a result, the actual starting operation of the vehicle internal combustion engine is started.
  • an additional switch 9 is provided here, which is arranged parallel to the relay switch 2 and which is operated so that it is closed at least when switching the relay switch 2 and / or.
  • the additional switch 9 virtually forms a bypass to the relay switch 2 and serves to relieve the relay switch 2 in a switching operation.
  • the bypass switch 9 is supply side connected to the mains voltage U ßat and the ground side with a supply-side node of the starter motor 4.
  • an electronic unit 10 such as a control unit, is provided for driving the bypass switch 9.
  • Fig. 2a shows two switching cycles of the relay switch 2, wherein the state “low” the open position and “high” corresponds to the closed position of the relay switch 2.
  • Fig. 2b shows the switching state of the switch 9, wherein on the left of the dashed line a first mode and right of the dashed line, a second mode is shown.
  • the state “low” again corresponds to the open position and the state “high” to the closed position.
  • the switch 9 is controlled in such a way that it is closed shortly before a change of state of the relay switch 2 and shortly thereafter re-opened (see times t 0 and ti). As a result, the voltage drop across the relay switch 3 is reduced and thus reduces the risk of contact welding.
  • the parallel switch 9 is operated such that it is also switched on during the entire switch-on phase of the relay switch 2 (from t 0 to ti).
  • the switch 9 is turned on shortly before the time t 0 and turned off again shortly after the time ti. It is essential that the switch 9 is closed in a change of state of the relay switch 2.
  • the switch 9 can be realized for example as a transistor, in particular as a MOS transistor.

Abstract

L'invention concerne un démarreur pour démarrer un moteur à combustion interne, comprenant un relais de démarreur (1) avec un conjoncteur (2), qui permet d'ouvrir et/ou de fermer un itinéraire principal du courant (7) vers un moteur à démarreur (4). La durée de vie du relais de démarreur (1) peut nettement augmenter en prévoyant un autre commutateur (9) en parallèle au conjoncteur (1), lequel est commandé à l'aide d'un dispositif électronique (10) de manière à être fermé au moins au moment où le conjoncteur (2) s'ouvre ou se ferme.
