Definitions
- the invention relates to a method and a device for controlling a Cooling system of an internal combustion engine hereinafter also called an engine.
- Such a cooling system comprises a coolant pump which coolants through a Internal combustion engine conducts to cool them.
- a coolant pump for example connected a V-belt to the crankshaft of an internal combustion engine can be so that it is driven when the engine is running.
- DE 195 08 104 C2 also describes Method known for regulating a cooling circuit of an internal combustion engine in the between a warm-up phase, an operating phase and a run-on is distinguished.
- the warm-up and operating phase is with the engine started determined by the coolant temperature at the engine outlet, which with a Coolant temperature limit for the warm-up phase is compared.
- the value is undershot on warm-up phase and when reaching or Detected exceeding the value on operating phase.
- the Engine In the warm-up phase, the Engine is not initially cooled until it reaches an initial coolant temperature Has.
- one of the blowers generated air flow that is passed through a cooler module and that of the Coolant pump generated coolant flow depending on one Differential temperature setpoint of the coolant between the engine inlet and outlet is regulated.
- a differential temperature actual value necessary for the control is over the Heat flow from the internal combustion engine into the coolant is determined.
- the heat flow is in turn derived from the current coolant flow, the current engine load and the engine speed.
- the speed of the coolant pump changes with it the change in heat flow, so that short-term engine load and Changes in speed do not affect the operation of the coolant pump.
- EP 0 952 315 A1 discloses a control system for minimizing consumption electrical energy in a cooling system of an internal combustion engine disclosed. Based on the engine temperature and vehicle speed detected by sensors and ambient temperature, one control unit controls one fan and one electric pump for cooling the internal combustion engine. By means of the sensors An operating point is determined on the basis of a characteristic map by a dissipate certain amount of thermal energy from the engine, which is an optimal Ratio of the sum of the energy supplied to the fan and the pump indicates.
- the control system has the disadvantage that several sensors are necessary to record certain parameters on which the engine is cooled depending. In addition to the costs associated with each individual sensor, there is also a Default risk of the same. It also applies that the measuring accuracy at temperature measuring points can be reduced by external influences and thus a regulation based on the Temperature is limited.
- the object of the invention is a method and an apparatus for controlling a Provide cooling system of an internal combustion engine, being a reliable Cooling is made possible.
- the invention is based on the basic idea of the cooling system and thus connected variably drivable coolant pump depending on one of the engine regulate the amount of fuel supplied.
- the performance of the Coolant pump over a range between preferably zero to one maximum pumping capacity (l / h) either continuously or in a variety of stages can be set variably.
- the supplied to the internal combustion engine Amount of fuel related to engine warming can be Regulation of the coolant pump and thus the cooling of the engine with foresight take place on the basis of the fuel currently consumed.
- the function of the Heat input from the engine into the coolant to fuel mass flow is largely similar for all combustion concepts.
- the sum of the fuel quantity supplied since the ignition of the engine ⁇ m ' KS is compared with a so-called target fuel quantity m target . If the setpoint is undershot, as is the case, for example, when the engine is cold started, the engine is not cooled by the cooling system first, unless with a volume flow requested for other needs in the cooling system, for example for a heater.
- This has the advantage that the warm-up phase of the engine can be shortened and the fuel consumption can be reduced, in contrast to engines in which the coolant pump is connected to the crankshaft. In these engines, the coolant pump is automatically driven when the engine is started, so that the engine is cooled before it warms up.
- cooling takes place by switching on the coolant pump.
- the performance of the coolant pump is determined as a function of at least one of the following parameters, such as engine speed nMot, engine load, outside temperature and / or an average over a predetermined time interval (for example 30 seconds) of the fuel quantity m ' KS .
- the cooling system and the coolant pump are preferably additionally regulated as a function of the coolant temperature.
- the instantaneous temperature of the coolant T Mot is compared with a desired coolant temperature T Soll . If the target value T target is exceeded, the engine is cooled by the cooling system, the output of the coolant pump being determined as described above as a function of the engine speed nMot, the engine load, the outside temperature and / or an average value of the fuel quantity m ' KS can.
- This has the advantage that the operating point of the coolant pump can be variably adjusted depending on certain parameters such as the outside temperature or the load. This operation is particularly advantageous when the engine is hot idling and the engine is turned off.
- the cooling system and the coolant pump can be regulated depending on the engine oil temperature.
- the instantaneous engine oil temperature T Oil is compared with a target engine oil temperature T Soll . If the value falls below the target value T target , there is no cooling by the coolant pump, unless with a volume flow requested for other needs in the cooling system, for example for a heater. Furthermore, the cooling starts as soon as the target engine oil temperature T target is exceeded.
- the performance of the coolant pump is determined as a function of the engine speed nMot, the engine load, the outside temperature and / or an average of the fuel quantity m ' KS .
- the cooling system is preferably controlled additionally depending on the connection or the heat input of such Facility. This is preferably dependent on a degree of connection
- the heater determines the performance of the coolant pump.
- An advantage is, that the pump meets the requirements of the additional facilities is operated, even if this would not be necessary for cooling the motor. This is, for example, for supplying the heating or cooling of the automatic transmission e.g. the case when idle.
- An additional one may not be necessary Water pump for heating.
- the degree of connection of the heating for example, approximately 100%, the performance of the coolant pump increased accordingly so that this part of the coolant to the heat exchanger the heater can pump. If no heating is switched on, the one previously determined is determined Maintain coolant pump performance.
- control system compares a first coolant temperature threshold value with the current coolant temperature T Mot . If the threshold value is exceeded, the coolant pump is operated at a predetermined power at least within a predetermined time interval, so that the engine is cooled further. This has the advantage that the engine is adequately cooled by the ambient temperature even when it is running hot or when it is additionally heated.
- Coolant temperature a second coolant temperature threshold, so the coolant pump with a predetermined power within a predetermined Time interval operated and the engine cooled. This has the advantage that the engine continues is cooled and so temperature peaks in the engine after the engine has stopped high load can be prevented.
- the duration of the wake depends on the temperature is exceeded to the setpoint, but a defined duration is not may be exceeded (battery discharge).
- control loop is closed and again a calculation of the pump performance based on the amount of fuel supplied performed to achieve continuous cooling of the engine.
- the control method according to the invention shown in FIG. 1 it is first determined whether the engine is in operation. In this case, the sum of the fuel quantity since the ignition of the engine ⁇ m ' KS is compared with a predetermined target value m target of the fuel quantity. In a further query, the current temperature of the coolant T Mot is compared with a target temperature T Soll of the coolant.
- the coolant pump is initially not operated, it unless with a volume flow requested for other needs in the cooling system for example for a heater. This will remove heat from the engine prevented and the engine warms up quickly.
- cooling begins. This is the performance the coolant pump as a function of an average of the fuel quantity in one certain time interval (e.g. 30 seconds), the engine speed and / or the engine load certainly.
- Other parameters such as the operating parameters of the cooling system are here also conceivable.
- the coolant pump can be operated when a Volume flow for other needs in the cooling system is requested for example for a heater.
- the regulation of the performance of the coolant pump depends on the activated heating has priority over the control depending on whether the Setpoint values for the fuel quantity or the coolant temperature are below or exceeded become.
- a heater is switched on and depending on the performance of the coolant pump regulated.
- an activated Heating removes heat from the engine in which at least part of the heated Coolant is pumped to the heater and there via a heat exchanger Vehicle interior is discharged.
- Coolant temperature threshold e.g. 115 ° C
- the pumping power of the coolant pump is below a predetermined value sufficient for cooling that Pump power increased to this predetermined value and in a predetermined Time interval cooled further. If the threshold is undershot, the performance remains the coolant pump unchanged.
- the next step is to determine whether the engine is still operating. In this If the control circuit closes, the pump power is recalculated based on the amount of fuel supplied to ensure continuous cooling of the engine guarantee.
- a second, lower coolant temperature threshold value e.g. 100 ° C
- the coolant pump cools the engine with a predetermined power in a predetermined time interval of preferably 60-300 Seconds. If the second coolant temperature threshold is undershot, this is done no further cooling.
- a cold start with or without heating and hot idling is aimed at to meet the requirements of heating and component temperatures, and by suppressing forced convection, the heat transfer is minimal hold and thus to get faster component heating.
- the absolute temperature level of the cooling system is still regulated by a thermostat. This can be used as a conventional thermostat with an expansion element (heated as Map thermostat or unheatable) or as an electrical actuator his.
- An electrically operated coolant pump is preferably used Coolant pump used, which has its own drive.
- a coolant preferably cooling water used. All values mentioned here for the Pump output, temperatures and time intervals are only examples.
