Definitions

  • the invention relates to a method and a device for controlling a vehicle generator.
  • the temperature detected by means of the temperature sensor is used, for example, to monitor limit temperatures, for example the maximum operating temperature of the ASIC. If the specified limit temperature is exceeded, then the controller responds in a predetermined manner. For example, it reduces or limits the excitation current to reduce the output power of the generator. This procedure provides protection against thermal overloading of the ASIC.
  • controllers or of the generator can be monitored in a corresponding manner with regard to overheating, provided that a correlation exists with the temperature measured in the region of the ASIC. This influence of the regulator on the generator can go so far that the complete supply of the On-board network is disabled, so the generator no longer delivers power.
  • a device for controlling a vehicle-three-phase generator has a rectifier arrangement and a voltage regulator which is provided for regulating the output voltage of the generator.
  • the voltage regulator includes a circuit having temperature sensing means thermally coupled to a generator component or the rectifier assembly.
  • the vehicle three-phase generator is operable in an over-excited state. From reaching a first predetermined threshold, which is a predetermined temperature or a first predetermined speed, the excitation current or the generator current is lowered. After reaching a second predefinable threshold, which is the predeterminable temperature or a second predetermined speed, the excitation current or the generator current is raised again. Due to the temperature measurement described above, the generator can be operated in the over-excited range until the temperature reaches a critical value. The subsequent reduction of the excitation current ensures that the temperature of the generator or of the regulator drops again.
  • a method with the features specified in claim 1 and a device having the features specified in claim 2 have the advantage that already at a time before the controller applied to the generator with the output power of the generator reducing drive signals, an external control device defined by Actions, in particular a shutdown of non-safety consumers, can provide for a reduction of the output power of the generator.
  • an external control device defined by Actions in particular a shutdown of non-safety consumers, can provide for a reduction of the output power of the generator.
  • the controller Only when the measured temperature exceeds the second predetermined temperature threshold, from which must be expected with a heat-related damage or destruction of components of the controller and / or the generator, the controller responds with a supply of the output power of the generator reducing drive signals for the generator.
  • Increased temperature is understood to mean a temperature which is higher than the first predefined temperature threshold value, but lower than the second temperature threshold value, above which damage to components of the controller and / or the generator must be expected.
  • overtemperature is meant a temperature which is higher than the second predetermined temperature threshold.
  • FIG. 1 shows a block diagram of a device for controlling a vehicle generator, from which the essential features of the invention can be seen.
  • FIG. 1 shows a block diagram of a device for controlling a vehicle generator.
  • the device shown has an alternator 1, which includes an excitation coil, three phase windings and a rectifier. This alternator is provided to supply the electrical system 15 of a vehicle.
  • the regulation of the output voltage of the generator 1 is performed by a generator controller 2, which is connected via a brush holder 3 to the generator 1.

  • the main task of the generator controller 2 is to provide control signals for the generator 1 during operation of the device, so that the generator 1 supplies a respectively required output power for the consumers of the electrical system 15. According to the present invention, during the operation of the apparatus, the control of the generator 1 is as follows:
  • the generator temperature provided by the temperature sensor 9 is compared in the ASIC 8 with a first predetermined temperature threshold and a second predetermined temperature threshold.
  • the second temperature threshold value is chosen to be greater than the first temperature threshold value and corresponds to a temperature value, at which, if exceeded, damage to components of the generator controller 2 and / or the generator 1 must be expected.
  • generator temperature is understood to mean a temperature which has been detected at a component of the generator device, for example at the generator regulator, at the rectifier, at the end shield of the generator or at another suitable point of the generator device.
  • the generator controller 2 If it is detected during the comparison that the generator temperature is lower than the first predetermined temperature threshold, then normal operation is present and the generator controller 2 provides the generator 1 in a conventional manner drive signals available to adjust the output power of the generator to the power supply present in the electrical system.
  • the generator controller 2 continues to supply the generator 1 with drive signals in the usual way in order to adapt the output power of the generator to the energy requirement present in the electrical system.
  • the ASIC 8 provides at its data interface 13 a message signal which contains information that the measured generator temperature is increased.
  • This message signal is transmitted via a data connection 14 to an external control unit 7.
  • the control unit 7 is provided to provide one or more control signals sl, s2, s3, s4 in response to this message signal.
  • non-safety-relevant consumers 6 are turned off.
  • the output power required by the generator 1 is reduced. This in turn causes the generator temperature to drop until normal operation is restored.
  • control unit 7 can also provide control signals in response to the message signal, by means of which other measures reducing the generator temperature are initiated.
  • control signals in response to the message signal, by means of which other measures reducing the generator temperature are initiated.

  • the generator controller 2 If it is detected during the comparison that the generator temperature is greater than the second predetermined temperature threshold, then there is an operation at excess temperature, in which damage or even destruction of components of the generator controller 2 and also of the generator 1 must be expected. As soon as this overtemperature operation is detected, the generator controller 2 provides a drive signal for the generator which reduces the output power of the generator 1. As a result, the output power of the generator 1 is reduced without it being important whether non-safety-relevant consumers are switched on or not. In the present invention, after all, even when the measured generator temperature exceeds a predetermined first temperature threshold, this not yet critical temperature rise responds by this temperature increase is signaled to an external control device.
  • the generator controller 2 Only when these countermeasures do not lead to success and the generator temperature exceeds the predetermined second temperature threshold does the generator controller 2 provide drive signals to the generator 1, on the basis of which the output power of the generator 1 is reduced. Only then can the case occur that the energy required to supply safety-relevant consumers can no longer be provided by the generator alone.
  • a three-phase generator is shown.
  • other types of generators can be used, for example, five-phase generators, generators with a controller with high-side output stage, etc.

Abstract

L'invention concerne un procédé et un dispositif permettant de réguler un générateur de véhicule. A cet effet, la température du générateur, détectée au moyen d'une thermosonde, est comparée à une première valeur-seuil de température et à une seconde valeur-seuil de température. Si la température du générateur détectée est supérieure à la première valeur-seuil de la température, mais néanmoins inférieure à la seconde valeur-seuil de la température, un signal d'état est transmis à un appareil de commande extérieur qui initie des mesures visant à réduire la température du générateur, en réaction au signal d'état. Si la température du générateur détectée est supérieure à la seconde valeur-seuil de température, le régulateur du générateur envoie alors au générateur du véhicule un signal de commande réduisant la puissance utile du générateur du véhicule,.
