Definitions

  • the invention relates to an electrical starter device with the features mentioned in the preamble of claim 1.
  • So-called tip-starers are preferably used in comfort vehicles, which automatically execute the starting process for the internal combustion engine by means of a pulse. This creates a decoupling between the start selection and the start process.
  • the starting process is therefore controlled electronically and ended at the earliest possible time, for example when the internal combustion engine has a predefinable minimum speed. Since the starting process is not successful in all cases, it must be ensured that the starting process is not carried out indefinitely.
  • On the one hand to protect the starter battery on the other hand to avoid thermal overloading of the electrical starter. It has been shown that in electrical starter devices the hottest places with the highest risk potential are the carbon brushes and the commutator.
  • bimetallic switches are simple in terms of structure and working principle, but they are quite large. In addition, their switching behavior is highly hysteretic. The switch-on and switch-off temperature is also very tolerant. Since the bimetallic switch cannot be implemented with the low impedance required for the main flow, the solution chosen is that the bimetallic switch controls a relay that switches the starter main current. This arrangement also means a plug connection in the relay circuit and a double line between. Relay and the bimetal switch. This thus contributes to increasing the resistance in the P. ⁇ lais circuit.
  • the electrical starter device for an internal combustion engine offers the distribution that by the determination of a virtual operating temperature of the starter device, sensor costs and installation space, lines and an increase in resistance in the relay circuit no longer occur.
  • the switching on and off of the electrical starter device is not subject to hysteresis and the switching on and off temperature can be specified precisely.
  • the electrical starter device according to the invention offers the advantage that the problems of the different temperature response between the sensor point and the actual monitoring point (brushes, commutator) no longer occur.
  • the electrical starter device according to the invention thus offers the advantage that — without direct measurement — the temperature range of interest is detected very precisely and the temperature of the electrical starter device can be determined precisely.
  • the virtual operating temperature is at least least depending on the starter current is determined. It is mainly the starter's operating circuit that heats the starter device. If this operating parameter is therefore taken into account when determining the virtual operating temperature, a heating model can be reproduced which reproduces the operating temperature of the starter device very precisely as a function of the switch-on duration of the starter device.
  • the switch-off time of the starter device is preferably taken into account.
  • the virtual operating temperature is therefore influenced as a function of the switch-off time. If the starter device is not in operation, the cooling temperature or the temperature drop is determined on the basis of the switch-off duration, based on the previously determined higher virtual operating temperature.
  • the virtual operating temperature is determined as a function of a reference temperature, in particular the ambient temperature of the starter device. It can therefore be provided that, during operation of the starter device, the increasing virtual operating temperature is determined on the basis of the ambient temperature. In the cooling phase, however, it can be stipulated that the virtual 3-temperature temperature cannot fall below the ambient temperature. It is preferably provided that the device for determining a virtual operating temperature has a detection means for the ambient temperature. It is thus possible to carry out a comparison between the virtual operating temperature and the ambient temperature, since the detection means determines the actual ambient temperature. A reference to the virtual operating temperature can thus be established with an actually measured temperature, in particular the ambient temperature or the reference temperature.
  • One exemplary embodiment is characterized in that the virtual operating temperature is determined as a function of a current ratio (i / i 0 ) b .
  • a normalized starting current is therefore taken into account, the actual starter current being considered with i and a reference current being taken into account with i 0 .
  • the exponent b can be taken as a star-specific parameter.
  • the virtual operating temperature is determined as a function of the current ratio, a reference can also be made as to whether the starter heats up very quickly or less strongly. If, for example, due to temperature influences on the internal combustion engine, an increased torque must be applied to the starting process, this usually also results in a higher starter current. The starter device would therefore heat up much faster.
  • the electrical starter device If the electrical starter device is switched off for a longer period of time, it can be provided that a reduction in the cooling degree of the virtual drive temperature is assumed. This means that as the virtual operating temperature falls, it approaches the ambient temperature more and more slowly. This influence is therefore also taken into account when determining the virtual operating temperature.
  • the starter device depending on the switch-off time of the starter device and its current virtual operating temperature, this is equated with the ambient temperature. If the starter device has been out of operation for a very long time, for example, and the model calculation assumes that the starter device has already cooled completely, but the virtual operating temperature is above or is below the ambient temperature, in order to be able to start the system again from a reference point, the virtual operating temperature is equated with the ambient temperature. It is therefore assumed here that after a certain switch-off period, the starter device has the same temperature as the ambient temperature or reference temperature. This ensures that any errors which may be integrated in the determination of the virtual operating temperature are corrected at certain time intervals.
  • the virtual operating temperature is equated with the ambient temperature or reference temperature. If the virtual operating temperature decreases only very slightly over time, the virtual operating temperature can also be reset to the ambient temperature, for example, since it can be assumed that the actual operating temperature of the starter device with the ambient temperature is almost identical.
  • the virtual operating temperature is gradually adapted to the reference or ambient temperature depending on the switch-off duration and / or the cooling gradient.
  • the invention is explained in more detail below on the basis of an exemplary embodiment with reference to the drawing.
  • the single figure shows a block diagram of an electrical starter device with a device for determining a virtual operating temperature.
  • the electrical starting device for an internal combustion engine is provided with the reference number 1.
  • the starter device 1 a so-called tip starter, which can be controlled via a control unit 2 which, based on a start pulse 3, actuates the starter device 1 until the internal combustion engine to be started (not shown) has reached a predetermined speed.
  • the control unit then switches the starter device 1 off in order to protect it from damage.
  • the control device 2 preferably has a protective function against misuse of the starter device 1, so that, for example, it is not possible to activate the starter device 1 while the internal combustion engine is running.
  • the block diagram also shows a thermal monitoring device 4 for the thermal monitoring contactor of the starter device 1.
  • the monitoring device 4 preferably forms a unit with the control device 2 and is in particular integrated into the control device 2.
  • the monitoring device is a device 5 for determining an virtual operating temperature of the starter device 1 is formed.
  • the device 5 determines the virtual operating temperature as a function of at least one operating parameter influencing the operating temperature of the starter device 1.
  • a temperature model is thus generated that comes very close to or corresponds exactly to the actual operating temperature of the starter device 1.
  • This operating parameter is, for example, the main start current i, which is detected by the device 5.
  • the device 5 also detects whether the starter device 1 is switched on or off, that is to say activated via the control unit 2 or deactivated.
  • the heating model ⁇ preferably works according to a method which contains a heating gradient ⁇ T E proportional to a current ratio (i / i 0 ) b , where i 0 represents a reference current, in particular nominal current, of the starter device 1, b forms a starter-specific parameter and can be selected depending on the type of model.
  • the heating gradient ⁇ T E is transmitted to ⁇ in ⁇ integration and adjustment device 7, which, by integration from the heating gradient ⁇ T £, determines the virtual module temperature or 3 ⁇ drive temperature T and is further transmitted to the control unit 2.
  • the control unit 2 decides whether the starter device 1 can be operated further or has to be taken out of operation when the virtual operating temperature T v reaches the maximum possible limit operating temperature of the starter device 1.
  • the thermal cooling gradient .DELTA.T A is determined in a cooling model 8 and transmitted to the integration and calibration device 7.
  • the cooling gradient: ⁇ T A is influenced by the level of the absolute temperature T, which, when the cooling phase starts, is assumed to be the previously determined virtual operating temperature, which became apparent during the operation of the starter device 1.
  • the cooling gradient ⁇ T A also influences the switch-off duration ⁇ t of the starter device 1. If there is a high absolute temperature, the cooling gradient ⁇ T A increases .
  • the cooling degree ⁇ T A decreases with increasing switch-off time ⁇ t.
  • the integration and adjustment device determines the falling virtual operating temperature T and transmits this to the control unit 2.
  • the device 5 has a temperature detection means 9 which, for example, can be designed as a temperature sensor which determines the ambient temperature of the starting device 1.
  • a comparison model 10 the detected ambient temperature is compared with the virtual operating temperature.
  • the switch-off duration ⁇ t of the starter device 1 is taken into account. If the starter device 1 is, for example, very long out of operation, it is determined in the adjustment model 10 that the virtual operating temperature and the ambient temperature have the same value.
  • the virtual operating temperature T v thus determined, which now corresponds to the ambient temperature, is transmitted to the control unit 2. This ensures that a model error that may be integrated in the integration and comparison device 7 is corrected at certain time intervals.
  • the temperature detected on the control unit 2 or another reference temperature can also be used, which, like the ambient temperature, is then used for the adjustment of the virtual operating temperature T v .
  • the heating model 6 and the cooling model 8 preferably operate according to a so-called description function, the individual influences, the gradients .DELTA.T E and .DELTA.T A, each being represented by a factor with a corresponding dependency. Since the main starting current has a very strong influence on the heating gradient ⁇ T ⁇ , this can be assigned a high factor, for example. In particular, all essential dependencies can be recorded. These include in particular the dependence of the heating on the starter current, the dependency on the differential temperature between the commutator of the starter device and the ambient temperature, the dependence on the absolute temperature and the dependence on the time. In the temperature range of interest, i.e. essentially around the switching temperature range of the starter device, can thus achieve a high correspondence of the virtual operating temperature! ⁇ with measured values actually obtained in the searcher. It is evident that the virtual operating temperature T v reflects the actual temperature of the starter device 1, in particular the commutator and the brushes, very precisely.
  • the virtual operating temperature T v is determined, that is to say quasi an assumed operating temperature of the starter device, additional conditions can be taken into account in the heating and cooling models 6 and 8. For example, it may be advantageous to increase the switch-off temperature in individual cases, for example in order to be able to actuate the starter even in emergency situations.
  • a possibly integrated temperature model error is corrected at certain time intervals with a secured ambient temperature, so that the virtual operating temperature T v is reset to a saved value.
  • All models 6, 8 and 10 are preferably structured as a description function with individual factors corresponding to different dependencies. These parameters are therefore easily adaptable to vehicle-specific counterparts.
  • Modules 6, 8 and 10 are preferably implemented by means of a microprocessor, in which the models can be implemented using analytical equations with minimal memory requirements as well as using tables with minimal computing effort.
  • the analytical equations or the tables are determined in previous heating tests of the starter device 1, in order to be able to determine the actual heating of the starter device 1, for example, in the case of a specific main starting current during a predetermined period of time.
