Definitions

  • the technical environment is based on the DE 197 14 496 A1 referenced.
  • the method according to the invention does not only include a simple one Query whether cooling of the actuators is necessary or not, but it is generally intended to be the amount of the actuator for cooling purposes guided fluid flow can be set so that ultimately a critical (maximum) component temperature of the actuators is not exceeded becomes.
  • This setting is carried out by means of a suitable valve device, which a more or less large amount of cooling fluid through the Actuators flow, in particular or essentially in Dependence on the current component temperature of the actuators.
  • the current component temperature of an actuator can be determined using a suitable sensor are measured, after which in an electronic Control unit a query or a comparison is made whether this current Temperature far below or near the critical maximum actuator component temperature lies. The result of this comparison will be one more or less large amount of cooling fluid through the actuator (s) headed.
  • an electrical characteristic of an actuator corresponding to the current component temperature can thus be determined in an electronic control unit assigned to the actuators on the basis of the electrical current flowing through the solenoid coils of the actuator and compared in an electronic control unit with the critical component temperature or a critical electrical characteristic corresponding to it , whereupon the latter control unit controls the said valve device with regard to the amount of the required cooling fluid flow.
