Abstract

Die Erfindung betrifft ein Kühlsystem mit einer adaptiven Regelung der Pulsweitenansteuerung für die Betätigungselemente an den Ventilen des Thermostaten. Unter Einbeziehung der aktuellen Umgebungstemperatur wird zunächst mit einer zuvor ermittelten und abgespeicherten Grundadaption möglichst schnell das anzustrebende Temperaturniveau im Kühlmittelkreislauf angestrebt. Es sind je nach Lastzustand und Umgebungsbedingungen drei verschiedene Temperaturniveaus als Sollgrößen für die Einregelung der Kühlmitteltemperatur vorgesehen. Nach erstmaligem Erreichen der nach dem Start aktuell anzustrebenden Kühlmitteltemperatur wird die Regelung auf eine Feinadaption umgestellt. Mit der Feinadaption wird die aktuell einzuregelnde Kühlmitteltemperatur in Abhängigkeit der Solltemperatur und der Außentemperatur möglichst konstant gehalten. Ändert sich auf Grund einer Änderung des Lastzustandes des Motors die von der Regelung anzustrebende Solltemperatur des Kühlmittels, wird das neu anzustrebende Temperaturniveau mit der Feinadaption eingestellt. Dies hat den Vorteil, dass bei der Inbetriebnahme des Kraftfahrzeugs mit den Einstellungen der Grundadaption sofort die aktuell einzuregelnde Kühlmitteltemperatur angefahren werden kann.The invention relates to a cooling system with an adaptive control of the pulse width control for the actuators on the valves of the thermostat. Taking into account the current ambient temperature, the desired temperature level in the coolant circuit is initially aimed for as quickly as possible with a previously determined and stored basic adaptation. Depending on the load condition and ambient conditions, three different temperature levels are provided as setpoint variables for regulating the coolant temperature. After the initial attainment of the coolant temperature to be aimed for after the start, the control is converted to a fine adaptation. With the fine adaptation, the current coolant temperature to be regulated is kept as constant as possible in dependence on the setpoint temperature and the outside temperature. If, due to a change in the load state of the engine, the setpoint temperature of the coolant to be aimed for by the control changes, the newly desired temperature level is set with the fine adaptation. This has the advantage that when commissioning the motor vehicle with the settings of the basic adaptation immediately the coolant temperature currently einzuregelnden can be approached.
