Title (EN) METHOD FOR CONTROLLING THE COOLING WATER TEMPERATURE OF A VEHICLE WITH AN INTERNAL COMBUSTION ENGINE
(FR) PROCEDE DE REGULATION DE LA TEMPERATURE DE L'EAU DE REFROIDISSEMENT D'UNE AUTOMOBILE A MOTEUR A COMBUSTION INTERNE
(DE) VERFAHREN ZUR REGELUNG DER KÜHLWASSERTEMPERATUR EINES KRAFTFAHRZEUGS MIT EINEM VERBRENNUNGSMOTOR
Abstract:
(EN) A method for controlling the cooling water temperature of a vehicle with an internal combustion engine is disclosed, whereby at least one further sensor, for example, a knock sensor, or a vehicle control unit is used for determining the cooling water temperature. A control unit (2) determines a set value (tset) from the input values, by means of a control loop (29, 31, 32), taking account of the knocking behaviour. The regulated set temperature is used by a motor control unit to set the advance angle to early , for example.
(FR) L'invention concerne un procédé permettant de réguler la température de l'eau de refroidissement d'une automobile à moteur à combustion interne, selon lequel il est prévu d'utiliser au moins un autre détecteur, par exemple un détecteur de cliquetis ou un appareil de commande du véhicule pour déterminer la température de l'eau de refroidissement. Un appareil de commande (2) détermine sur la base des signaux acheminés, une valeur théorique (Tthéor.), compte tenu du comportement en cliquetis, au moyen d'une boucle de régulation (29, 31, 32). La température théorique régulée est utilisée par un appareil de commande du moteur (8) pour régler par exemple l'angle de came sur « avance ».
(DE) Erfindungsgemäss wird ein Verfahren zur Regelung der Kühlwassertemperatur eines Kraftfahrzeugs mit einem Verbrennungsmotor vorgeschlagen, bei dem mindestens ein weiterer Sensor, beispielsweise ein Klopfsensor, oder ein Fahrzeugsteuergerät zur Bestimmung der Kühlwassertemperatur verwendet wird. Ein Steuergerät (2) ermittelt aus den zugeführten Signalen einen Sollwert (tsoll) unter Berücksichtigung des Klopfverhaltens mittels einer Regelschleife (29, 31, 32). Die geregelte Solltemperatur wird dabei von einem Motorsteuergerät (8) verwendet, um den Zündwinkel beispielsweise auf 'früh' zu stellen.
