Definitions
- the invention relates to a coolant temperature control system for the cooling system of an internal combustion engine in motor vehicles with an electrically heated thermostatic valve, its operation by means of electrical Current can be shifted in the direction of cooler operation is.
- Such a coolant temperature control system is, for example known from DE 43 24 178 A1.
- a cooler and a thermostatic valve with which the temperature of the coolant in a warm-up mode, a mixed operation and a cooler operation adjustable is provided.
- the thermostatic valve contains an expansion element that is used to reduce the coolant temperature is electrically heated.
- the expansion element is designed so that the coolant temperature is without heating of the expansion element in warm-up mode and / or in Mixed operation is regulated to an upper working limit temperature.
- This upper working limit temperature is preferred equal to the most economical operating temperature of the Internal combustion engine and is only slightly smaller than a maximum permissible operating temperature.
- This upper one Working limit temperature can be, for example, approx. 105 ° C.
- this upper working limit temperature can last for other systems regulating the coolant flow be high.
- H. without a Defective is with a possible coolant flow control Usually overheating can be prevented.
- the heat exchanger temperature for heating or air conditioning systems via the timed activation of valves regulated in permissible ranges.
- a Defect for example a permanently open valve, the coolant can flow freely into the heat exchanger. This can be particularly the case with a coolant temperature around the range of the upper working limit temperature faults, damage and possibly total failure of the Run heating or air conditioning.
- means are provided for detecting a defect in a further system regulating the coolant flow in the motor vehicle. If this system detects a defect, the thermostatic valve is energized. When the thermostatic valve is energized, the operating mode of the thermostatic valve is shifted in the direction of the cooler operation, as a result of which the coolant temperature is reduced if a defect is present. This generally protects all systems and parts that come into contact with the coolant against overheating.
- the energization of the thermostatic valve is carried out in such a way that the coolant temperature is below a predetermined coolant temperature threshold.
- this protects against overheating of the systems in the event of a defect; B. a reduction in fuel consumption, not having to give up completely.
- a compromise is thus achieved between the requirements for the internal combustion engine and the requirements for further systems through which the coolant flows with respect to the coolant temperature.
- the detection of a defect is carried out by means of plausibility monitoring of output signals of the systems through which the coolant flows.
- These output signals are preferably existing input signals of a control device which generally regulates the electrical energization of the thermostatic valve. This enables a further function of the coolant temperature control system without having to make design changes to the hardware. For example, a separate error signal line is saved.
- An electronic engine control unit 1 which also performs other functions of an internal combustion engine in motor vehicles, not shown here, contains, inter alia, a function block 4.
- the electronic engine control unit 1 has a plurality of input and output signals.
- a possible output signal is, for example, the current switching signal S T.
- Input signals of the electronic engine control unit 1 are the coolant temperature signal T Kist , an air conditioning readiness signal S AC and an air conditioning compressor activation signal S KO .
- the air conditioning readiness signal S AC and the air conditioning compressor switch-on signal S KO are output signals of an air conditioning control unit 2 of an air conditioning system, which here is an example of a further system regulating the coolant flow.
- the air conditioning control unit 2 emits, inter alia, a valve switching signal S V , with which a valve is actuated in a clocked manner, in particular by a pulse-width-modulated signal, in order to regulate the flow of coolant for the internal combustion engine accordingly in order to achieve a desired heat exchanger temperature.
- a valve switching signal S V with which a valve is actuated in a clocked manner, in particular by a pulse-width-modulated signal, in order to regulate the flow of coolant for the internal combustion engine accordingly in order to achieve a desired heat exchanger temperature.
- a bus system such as. B. exchange the known motor vehicle bus CAN.
- the climate control device 2 controls to output the valve switching signal S V a diagnosable driver circuit 3 depending on various input signals, such as. B. from signals of the control unit of an air conditioning system.
- the air conditioning control unit 2 detects via the diagnostics-capable driver circuit 3 when a proper valve switching signal S V cannot be output.
- the valve switching signal S V can cause the valve to open continuously due to a defect. This would allow unhindered heating coolant to flow through the heat exchanger and endanger the functionality of the air conditioning system.
- This is an example of the presence of a defect in a system regulating the coolant flow, which is initially recognized by the air conditioning control unit 2 and is subsequently communicated to the electronic engine control unit 1 or the function block 4, for example.
- This error can be reported, for example, via the CAN bus or, if such a bus is not present, via the air conditioning standby and air conditioning compressor activation signals S AC and S KO , which are present anyway.
- the air conditioning system ready signal S AC informs the electronic engine control unit 1 that the driver has requested that the air conditioning system be switched on.
- the air conditioning compressor switch-on signal S KO the information is transmitted to the electronic engine control unit 1 that the air conditioning compressor is active and, for example, the idle speed must therefore be increased.
- the predetermined coolant temperature threshold T Kdef can be defined , for example, as a coolant temperature setpoint T Ksoll instead of a setpoint during normal operation as a function of various operating parameters in the event of a defect. Such a setpoint specification in the event of a defect can, like in normal operation, be carried out using characteristic diagrams which are stored in the control unit. Different errors can also be communicated and recognized, for example via the CAN bus.
- the coolant temperature threshold T Kdef can thus also be set differently in accordance with the type of defect or also in accordance with the system which is currently transmitting a defect.
- Coolant temperature control system created that one hand flexible, but also realized in a cost-saving way can be.

Description
Erfindungsgemäß sind Mittel zur Erkennung eines Defekts einer weiteren den Kühlmitteldurchfluß regelnden Anlage im Kraftfahrzeug vorgesehen. Bei erkanntem Defekt dieser Anlage wird eine Bestromung des Thermostatventils vorgenommen.
Mit der Bestromung des Thermostatventils wird die Betriebsweise des Thermostatventils in Richtung Kühlerbetrieb hin verschoben, wodurch eine Reduzierung der Kühlmitteltemperatur bei Vorliegen eines Defekts stattfindet.
Hierdurch werden allgemein alle Anlagen und Teile, die mit dem Kühlmittel in Kontakt kommen, vor Überhitzung geschützt.
Hierdurch wird einerseits vor einer Überhitzung der Anlagen bei einem Defekt geschützt, andererseits kann jedoch durch die Vorgabe der Kühlmitteltemperatur-Schwelle noch eine ausreichende Kühlmitteltemperatur eingehalten werden, um die Vorteile einer hohen Kühlmitteltemperatur für den Verbrennungsmotor, wie z. B. eine Senkung des Kraftstoffverbrauchs, nicht vollkommen aufgeben zu müssen. Somit wird ein Kompromiß zwischen den Anforderungen an den Verbrennungsmotor und den Anforderungen an weitere vom Kühlmittel durchflossene Anlagen bezüglich der Kühlmitteltemperatur erreicht.
Vorzugsweise sind diese Ausgangssignale ohnehin vorhandene Eingangssignale eines Steuergeräts, das allgemein die elektrische Bestromung des Thermostatventils regelt.
Hierdurch ist eine weitere Funktion des Kühlmitteltemperatur-Regelsystems ermöglicht, ohne konstruktive Änderungen der Hardware vornehmen zu müssen. Beispielsweise wird eine eigene Fehlersignalleitung eingespart.
