Abstract
Verfahren zur Steuerung des Kühlkreislaufs einer Brennkraftmaschine, wobei der Kühlkreislauf eine vorgegebene Solltemperatur (Ts) aufweist, wobei für einen Warmlauf der Brennkraftmaschine zeitweise eine Warmlaufsolltemperatur (Tsw) vorgesehen ist, die höher ist als die Solltemperatur (Ts), dadurch gekennzeichnet, dass der Kühlkreislauf nicht bei der Solltemperatur (Ts) sondern beim Erreichen der Warmlaufsolltemperatur (Tsw) erstmalig aktiviert wird, indem ein Drosselventil (6) und eine Pumpe (7) des Kühlkreislaufs (3, 4, 5) aktiviert werden.Method for controlling the cooling circuit of an internal combustion engine, wherein the cooling circuit has a predetermined set temperature (Ts), for a warm-up of the internal combustion engine temporarily a warm-up target temperature (Tsw) is provided which is higher than the set temperature (Ts), characterized in that the cooling circuit not at the target temperature (Ts) but when reaching the warm-up target temperature (Tsw) is first activated by a throttle valve (6) and a pump (7) of the cooling circuit (3, 4, 5) are activated.
Description
Stand der TechnikState of the art
Die Erfindung geht aus von einem Verfahren bzw. einer Vorrichtung zur Steuerung des Kühlkreislaufs einer Brennkraftmaschine nach der Gattung der unabhängigen Patentansprüche. Kühlkreisläufe von Brennkraftmaschinen werden üblicherweise auf eine vorbestimmte Solltemperaturen geregelt.The invention relates to a method and a device for controlling the cooling circuit of an internal combustion engine according to the preamble of the independent claims. Cooling circuits of internal combustion engines are usually controlled to a predetermined setpoint temperatures.
Aus der
Vorteile der ErfindungAdvantages of the invention
Das erfindungsgemäße Verfahren bzw. die erfindungsgemäße Vorrichtung haben demgegenüber den Vorteil, dass ein verbesserter Warmlauf der Brennkraftmaschine erreicht wird. Insbesondere wird eine schnellere Erwärmung der Brennkraftmaschine während des Warmlaufbetriebs sichergestellt.The inventive method and the device according to the invention have the advantage that an improved warm-up of the internal combustion engine is achieved. In particular, a faster heating of the internal combustion engine is ensured during the warm-up operation.
Weiterbildungen und Verbesserungen ergeben sich durch die Merkmale der abhängigen Patentansprüche. Die Warmlaufsolltemperatur wird zweckmäßiger Weise zwischen der Solltemperatur und dem Siedepunkt des Kühlmittels in dem Kühlkreislauf gewählt. Zur Erkennung des Warmlaufbetriebs kann die unmittelbar nach dem Start der Brennkraftmaschine vorliegende Temperatur der Brennkraftmaschine herangezogen werden. Beim Erreichen der Warmlauftemperatur wird der Kühlkreislauf aktiviert, indem ein entsprechendes Steuerventil bzw. eine Pumpe angesteuert werden. Dabei sollte der Volumenstrom mit einer vorgegebenen Abhängigkeit langsam erhöht werden, indem die Öffnung des Ventils und/oder die Pumpleistung der Pumpe beeinflusst werden. Nach dem Erreichen der Warmlaufsolltemperatur kann auch eine Übergangssolltemperatur vorgegeben werden. Diese Maßnahmen dienen dazu, nach dem Erreichen der Warmlaufsolltemperatur einen sanften überschwingungsfreien Übergang hin zur Solltemperatur zu gewährleisten.Further developments and improvements result from the features of the dependent claims. The warm-up target temperature is expediently selected between the setpoint temperature and the boiling point of the coolant in the cooling circuit. For detecting the warm-up operation, the temperature of the internal combustion engine present immediately after the start of the internal combustion engine can be used. Upon reaching the warm-up temperature of the cooling circuit is activated by a corresponding control valve or a pump are driven. The volume flow should be slowly increased with a given dependency by influencing the opening of the valve and / or the pump power of the pump. After reaching the warm-up set temperature, a transition setpoint temperature can also be specified. These measures serve to ensure a smooth overshoot-free transition to the setpoint temperature after reaching the warm-up target temperature.
