- another electronic circuit elements can then be the thermal Heating and steady-state behavior of the glow plugs in their full dynamics are emulated.
- the core of the physical Model consists of a physical one Energy storage whose energy content to glow plug temperature proportional or inversely proportional. at This physical energy store may be, for example around a heating element with appropriate thermal Ground or around a capacitor for storing electrical Act energy.
- the invention thus takes a physical Modeling the thermal behavior of the glow plugs, wherein the corresponding physical model in the annealing control is integrated. That can continue the illustration of the Engine operating state on the physical model include.
- the control of the glow plugs from every imaginable Operating state is optimized by this to shortest possible Response times to achieve the target temperature to achieve.
- the glow plug temperature becomes indirectly through a closed loop regulated from the control electronics for driving the Glow plugs, the correction module, the physical model leads back to the control electronics.
- the physical model can continue with measurement signals be coupled, the z. B. the temperature of the environment or at least in stationary operation of the glow plug play.
- a temperature sensor in the annealing control unit be provided or the signal of a temperature sensor of the engine are evaluated via an interface. to Determination of the temperature during stationary operation of the glow plug a resistance measurement takes place and if necessary an averaging over some or all built-in Glow plugs.
- the erf indungssiee device and the invention Methods provide improved repeat start protection for quick start glow plugs and low voltage glow plugs and offer the possibility of use as preemptive Controller.
- the image and thus storage of the temperature state the glow plug is independent of the power supply the electronics possible, so that too after a full reset of the current state of the Glow plugs can be easily and accurately detected and the optimal control can be selected.
- Das'physikalische Model that can be implemented in the control electronics can beyond that adjusted in the context of the production of the electronics become.
- Figs. 1 and 2 is a common metal executed Glow plug shown having a variable resistor which, as a rule, increases with increasing temperature increases.
- a glow plug controller via a suitable interface of one higher-level control unit, such as the engine control unit 1 of an engine 14 an annealing request to the annealing control unit 2, which is interpreted there, so that the glow plugs 3 energized according to the requirements become.
- one higher-level control unit such as the engine control unit 1 of an engine 14 an annealing request to the annealing control unit 2, which is interpreted there, so that the glow plugs 3 energized according to the requirements become.
- Fig. 3 is in the illustrated embodiment of the invention parallel to the glow plugs a physical model 4 of the glow plugs in Annealing control unit provided, which serves the thermal Map state of the glow plugs 3.
- This physical Model 4 is designed so that it is at least at a standstill Engine the temperature at the heater tip of a standard Glow plug depicts. This applies both to the heating as also for the cooling of the glow plug.
- the physical model 4 consists in principle of one physical energy storage whose energy content to Glow plug temperature proportional or inversely proportional is.
- This physical energy storage can, for example a capacitor whose state of charge is proportional to the temperature.
- the glow plug can also have the resistance of one accordingly dimensioned resistance temperature element with positive or negative resistance temperature coefficient serve within the physical model.
- the physical model 4 can also be complete in the form of computer-stored software, eg. B. as stored Map be formed.
- the State of the physical model 4 is evaluated and will from this an input variable 5 is formed, which is connected to the glow plug control 12 is located, the glow plugs 3 via a drive 15, z. B. in the form of circuit breakers controls.
- the engine control unit 1 a Annealing request is sent to the Glüh Kunststoff réelle 2, be the glow plugs 3 and parallel to the physical Model 4 controlled in the glow plug control.
- the state Model 4 is identified and analyzed and is available as Input 5 to the glow plug control 12 as feedback the glow plug temperature, so the glow plug control 2 the thermal state of the glow plugs during activation consider the glow plugs.
- the implemented in the glow control 2 physical Model 4 can capture the dynamics very accurately, so that a exact information about the actually on the glow plugs. 3 given temperature is given, giving far-reaching possibilities to capture and guide the temperature of the Glow plugs 3 opened.
- the temperature can of the physical model 4 with another temperature which is detected at a location that the ambient temperature reflects well.
- the ambient temperature reflects well.
- the physical model 4 in the annealing control 2 is implemented during the manufacture of the annealing control 2 easily the model or the integrated electronic Components can be adjusted, creating another Increased accuracy is achieved.
- the evaluation of the Resistance of the glow plugs 3 on the measurement of the current is not sufficient to the temperature, especially in dynamic To measure phases in sufficiently stationary phases the resistance of the glow plugs with the values of the However, compared to the physical model 4 further increase the accuracy or to check the Can serve plausibility.
- the controller 2 for targeted adjustment between the glow plug resistor and the output of the physical model 4 can by appropriate software and memory be implemented in the control electronics 12.
- the state of the physical model 4 thus becomes evaluated by suitable electronics and as a signal for processing for the control electronics 12 available posed.
- the physical model 4 Since the physical model 4, as mentioned, parallel to the glow plugs 3 is operated, d. H. an equivalent or proportional energy input, it forms that Heating behavior of the glow plugs 3 after. This replica should be designed so that the heating and cooling behavior at least when the engine is emulated.
- the physical model 4 in the annealing control 2 learns but not the energy inflow or outflow like a glow plug in the Combustion chamber by the combustion energy or the additional Cooling, for example, in overrun mode.
- the physical Model 4 fulfills its purpose and the temperature of the Glow plugs 3 simulates as well as possible, in addition to the Parallel control of the physical model 4 at the same time the additional positive or negative energy input by external influences, which deviate from the standard case, mathematically be added.
- the control of the physical model 4 with a fixed value. It is known that glow plugs during engine operation at least for diesel engines with direct injection except in marginal areas of low speed and very high load higher than the conditions with the engine stopped Have energy needs to set the target temperature of the glow plugs too hold. It is customary, the control electronics 12 so train that energy supply to the glow plugs so It is regulated that the glow plug temperature is independent of the engine operating conditions is maintained. This can be done at running engine and thus usually higher energy flow assumed the glow plugs as the engine is stationary be that the glow plugs have exactly the target temperature. The correction module 13 can be easily detected for this If the physical model 4 to one of the setpoint temperature force appropriate state.
- an even more accurate illustration of the actual Glow plug temperature required by the physical model 4 or in engines with indirect injection or other engines where the above-mentioned simple limit of the model is not sufficient by a fixed value may be the additional positive or negative energy input initially recorded by measurement and in correlation with the Engine control unit 1 or the glow control 2 available parameters, such as B. the injected fuel amount, the Speed, the inner moment, the air, engine, water or Oil temperature can be set. Due to the then received Data becomes an algorithm or a mathematical one Model created and integrated into the correction module 13, so that this the drive signal parallel to the Glühkerzenbestromung modified so that the physical model 4 follows the actual temperature at the glow plug.
