Definitions

  • the invention is based on an electric starter for one Internal combustion engine according to the type of the main claim. It is known, for example by measuring the armature current or the temperature of the carbon brushes with corresponding Sensors the thermal load of the electric starter (or in short form called starter).
  • devices have the disadvantage that they are relative are complex because additional sensors are required.
  • Temperature sensor needed, which is close to the Carbon brushes must be located so that it is essentially their Temperature can detect.
  • the known methods for Current measurement also requires a measuring element for example a shunt in the measuring line or at contactless measurement, e.g. B. a Hall sensor.
  • the electric starter according to the invention with the characterizing features of the main claim has the advantage that the installation of additional hardware such as sensors, wiring, control, etc. are not necessary because these functions can be realized with those already existing in the control circuit components. It is considered to be particularly advantageous that the measurement of the voltage ripple, for example by simulation or empirical measurement, can be used to deduce local temperature peaks, for example on the carbon brushes, or the load on the electric starter without great effort. In certain operating situations like the long one Cranking "after a cold winter night or when driving with the starter without engine support when loading the ship (because the tank is empty) can overload the starter, which would result in damage or destruction. This is advantageously avoided by the subject matter of the invention.
  • the armature current of the electric starter can be determined indirectly.
  • the Determination of the armature current is often necessary because with With the help of this value the temperature of the carbon brushes of the Electric starter can be determined.
  • a high armature current naturally results from the heating of the electric starter and the brush fire a correspondingly high temperature, while at a low armature current the temperature is lower.
  • the limit load can be adapted accordingly for the electric starter. So z. B. at high ambient temperature the limit be reduced accordingly, since then a possible Damage can occur earlier.
  • FIG. 1 shows a block diagram with a General overview and Figure 2 shows a flow chart.
  • FIG. 1 shows an electric starter 1 with a gear 9, the output shaft, which is not was shown, is arranged via a pinion 3 so that the pinion 3 during the starting phase of the internal combustion engine 6 engages in the teeth of a ring gear 4 and thus the Crankshaft of the internal combustion engine 6 in the intended Offset rotary movement.
  • On the electric starter 1 is a electrically operated single-track relay 2 attached, with whose help in the starting process the adhesion between the Electric starter 1 and the internal combustion engine 6 guaranteed becomes.
  • the single-track relay 2 is electrical above its Control input with the output of a control circuit 5 (ESC) connected to which a control output of an engine control unit 8 is connected.
  • ESC control circuit 5
  • Control circuit 5 At further entrances to the Control circuit 5 is a limit switch 10 and a Measuring input connected to the terminal 30 of the Starter circuit between a battery 7 and one Connection on single-track relay 2 is connected. Furthermore is the control circuit 5 with a fault memory 19 and connected to a protective device 20. From FIG. 1 it also follows that all the devices mentioned are one Have a negative connection to the negative pole of the battery.
  • the individual devices 10, 19, 20 together with the control circuit 5 in one housing can be installed.
  • FIG Control circuit 5 The mode of operation of FIG Control circuit 5 with the protective device 20 closer explained. It should be noted in advance that usually the control circuit 5 already contains elements that Single-track relay 2 before starting the electric starter 1 in this way control that the pinion 3 first in the ring gear 4th is pushed before the rotation begins. After this Tracking the pinion of the electric starter 1 on the Gear ring 4 of the internal combustion engine 6 switches this Single-track relay the starter current, so that the starter motor turns and over the mentioned pinion 3 and ring gear 4 the Crankshaft of the internal combustion engine drives. On the ring gear 4 generates the internal combustion engine 6 due to the friction and Compression of the pistons in the individual cylinders is not constant, but largely periodic braking torque.
  • the Starter current I (main current of the starter) depends on on the torque to be applied.
  • AD converter analog-to-digital converter
  • control circuit 5 another program routine contains with which the measured simultaneously at terminal 30 Ripple of the voltage is processed further, that depending on the starter type, the period or the frequency of the ripple is calculated, this with the Voltage values is linked to derive the current flow through the electric starter. This then becomes heating at various points in the electric starter, especially on the carbon brushes.
  • the parameters for the calculations come, for example, from empirical carried out comparative measurements that previously on a Comparison starter for heating the electric starter 1 or whose carbon brushes have been determined.
  • This calculated Value is supplied to the protective device 20, the latter Value with a corresponding value of a limit transmitter 10 compares. When exceeding or falling below this The limit value is preferably the starter current for the Electric starter 1 limited or switched off.
  • the control circuit 5 forms the average of the last Converter values, which is subtracted from the current converter value, in position 12 a difference value.
  • the Time between the zero crossings recorded and from it in Position 14 calculates the starter speed. From the digitized voltage value of the AD converter 19 and Starter speed is determined taking into account the type of Electric starter 1 calculates the starter current I (position 15).
  • the existing Data on the heating of the electric starter 1 by comparison with the values stored for the individual temperatures and taking into account the ambient temperature calculated.
  • the Protection device 20 for example, when the permissible limit temperature an abort of the starting process, to protect the electric starter 1 from possible damage protect.
  • the Control circuit has a fault memory 19 in which now the error messages of the protective device after exceeding of the specified limit value are saved.
  • This Error messages are, for example, with date, time, Long term temperature of electric starter 1 etc. saved until, for example, the next due Service read out this error message and if necessary the cause can be researched.
