Definitions
- the invention relates to a method and a device for controlling the heating of the glow plugs of a diesel engine.
- Such methods and devices serve to bring the glow plugs of a diesel engine to a desired temperature at which the engine can be started.
- the electronically controlled glow system ISS for diesel engines is known a method for controlling the heating of the glow plugs of a diesel engine, in after the determination of the temperature of the engine elements via the engine control and subsequent successful establishment of a communication between the engine control and the annealing control device is given the Glühanehlung or the GlühanTHER after completion of the initialization of the engine control.
- the thermal state of the glow plugs in particular of Glühartsartglühkerzen, for example, the residual temperature of the glow plugs after a previous heating at the repeat and include in the following control.
- the thermal state of the glow plugs can be implemented so far only from experience in the glow plug control unit.
- knowledge of the entire history is necessary, which requires non-volatile memory and a time base, if data must be included before a reset.
- the measurement of the glow plug temperature across the glow plug resistor eliminates as a way of determining the glow plug temperature due to the tolerances of the glow plugs with respect to their resistance profile because of the real existing tolerances and the different dynamic behavior. Calibration of the glow plugs is beyond that conceivable, since these are high-volume components.
- US 4,458,639 relates to a device for controlling the heating of the glow plugs of a diesel engine in which the output voltage generated by a glow plug temperature simulator containing a charge / discharge circuit is compared with a reference voltage from a reference voltage generator and the heating of the glow plug is controlled in dependence on the result of the comparison.
- the voltage across the glow plug is applied to the charge / discharge circuit to charge a capacitor thereof.
- the level of the reference voltage changes in response to changes in the voltage of the voltage source with which the glow plug is heated.
- the object underlying the invention is therefore to provide a method and an apparatus of the type mentioned above, with which the heating of the glow plugs of a diesel engine, including the thermal behavior of the glow plugs can be controlled without a measurement signal for reporting the temperature of the glow plugs ,
- the temperature range of the glow plug (up to 1,100 ° C for steel glow plugs, up to 1,500 ° C for ceramic glow plugs) is preferably projected onto the temperature range of the electronics (up to 125 ° C).
- a thermal model of the glow plugs is implemented in the glow control device by incorporating drive and evaluation electronics in conjunction with a resistance temperature element or element, or a combination of both elements.
- the feedback of the glow plug temperature from the physical model then enables a based on it Control or regulation of the glow plugs.
- the core of the physical model consists of a physical energy storage whose energy content is proportional to the glow plug temperature or inversely proportional. This physical energy store may be, for example, a heating element with a corresponding thermal mass or a capacitor for storing electrical energy.
- the control of the glow plugs from any conceivable operating state is optimized in order to achieve shortest possible response times to achieve the target temperature.
- the glow plug temperature is controlled indirectly by a closed loop, which leads from the control electronics for driving the glow plugs, the correction module, the physical model back to the control electronics.
- the physical model can be further coupled with measurement signals, the z. B. reflect the temperature of the environment or at least in stationary operation of the glow plug.
- a temperature sensor may be provided in the annealing control unit, or the signal of a temperature sensor of the engine may be evaluated via an interface.
- a resistance measurement and, if appropriate, an averaging over some or all built-in glow plugs.
- the erf indungssiee device and the inventive method provide improved repeat start protection at Schnellstartglühkerzen and low-voltage glow plugs and offer the possibility of use as a preemptive controller. Specifically, this means that a better and more accurate detection of the actual glow plug temperature, a guide of the glow plug temperature over the more accurate and easier detectable temperature of the physical model are possible.
- the mapping and thus storage of the temperature state of the glow plugs is independent of the power supply of the electronics possible, so that even after a complete reset the current state of the glow plugs can be detected easily and accurately and the optimal control can be selected.
- the physical model, which is implemented in the control electronics can also be compared during the production of the electronics. According to the invention, no static, but a dynamic memory is provided. Thus, the replication of the cooling behavior is possible even without operating voltage, so that an optimal control of the heating of the glow plugs to achieve the shortest standby time, ie startability of the engine can be achieved.
- a common metal glow plug which has a variable resistance, which typically increases with increasing temperature.
- Fig. 2 illustrated metal glow plug 6 with internal coil combination 7 a heating element without appreciable temperature coefficient, namely the heating coil 8, and a heating element with a positive temperature coefficient, namely the control or measuring coil 9, there is no sufficiently fast thermal coupling, so that the dynamics of the combustion chamber side candle tip not readily from the change in resistance can be determined, the said dynamics only relatively slowly follows.
- the resistances of all glow plugs from mass production scatter strongly and the resistance curve also correlates only insufficiently with the temperature profile. An adjustment or a sorting of all glow plugs is unthinkable due to the additional costs.
- additional temperature sensors 10 may be provided, they are associated with high costs and have a limited life over this.
- the detection and management of the heating behavior of the glow plugs are thus set narrow limits, which are already partially covered by the tolerance of real glow plugs, so that no additional statement about the present temperature of the glow plugs can be made at randomly distributed resistances.
- Fig. 3 is shown in a glow plug control via a suitable interface from a higher-level control unit, for example, from the engine control unit 1 of an engine 14 a Glühan project sent to the Glüh Kunststoff réelle 2, which is interpreted there, so that the glow plugs 3 are energized according to the requirements.
- a higher-level control unit for example, from the engine control unit 1 of an engine 14 a Glühan project sent to the Glüh concede réelle 2, which is interpreted there, so that the glow plugs 3 are energized according to the requirements.
- a physical model 4 of the glow plugs provided in the annealing control unit, which serves to map the thermal state of the glow plugs 3.
- This physical Model 4 is designed so that it reflects the temperature at the heater tip of a conventional glow plug at least when the engine is stationary. This applies to the heating as well as the cooling of the glow plug.
- the physical model 4 consists in principle of a physical energy storage whose energy content is proportional to the Glühkerzentemperatur or inversely proportional.
- This physical energy store may be, for example, a capacitor whose state of charge is proportional to the temperature.
- the resistance of a correspondingly dimensioned resistance temperature element with positive or negative resistance temperature coefficients can serve within the physical model.
- the physical model 4 can also be completely in the form of computer-stored software, eg. B. be formed as a stored map.
- the state of the physical model 4 is evaluated and from an input variable 5 is formed, which is located on the glow plug control 12, the glow plugs 3 via a drive 15, for. B. in the form of circuit breakers controls.
- the glow plugs 3 and, in parallel, the physical model 4 in the glow plug control are actuated.
- the state of the model 4 is determined and analyzed and is an input 5 to the glow plug controller 12 as a feedback of the glow plug temperature, so that the glow plug control 2 can take into account the thermal condition of the glow plugs in the control of the glow plugs.
- the implemented in the glow control 2 physical Model 4 can detect the dynamics very accurately, so that precise information is given about the temperature actually present at the glow plugs 3, which opens up far-reaching possibilities for detecting and guiding the temperature of the glow plugs 3.
- the temperature of the physical model 4 may be compared to another temperature sensed at a location that best reflects the ambient temperature. This may be a measuring point 11 on the metal stamped grid, which does not experience a large current, for example the communication interface.
- the model or integrated electronic components can be easily adjusted, thereby achieving a further increase in accuracy .
- the evaluation of the resistance of the glow plugs 3 via the measurement of the current is insufficient to measure the temperature, especially in dynamic phases, the resistance of the glow plugs can be compared with the values of the physical model 4 in sufficiently stationary phases Increase the accuracy or can serve to verify the plausibility.
- a corresponding functionality of the controller 2 for targeted matching between the glow plug resistor and the output signal of the physical model 4 can be implemented by appropriate software and memory in the control electronics 12.
- the state of the physical model 4 is thus evaluated by suitable electronics and provided as a signal for processing for the control electronics 12 available.
- the physical model 4 Since the physical model 4, as mentioned, is operated in parallel with the glow plugs 3, ie an equivalent or receives proportional energy input, it forms the heating behavior of the glow plugs 3 after. This replica should be designed so that the heating and cooling behavior is simulated at least when the engine is stopped. However, the physical model 4 in the glow control 2 does not experience the energy supply or outflow as a glow plug in the combustion chamber by the combustion energy or the additional cooling, for example, in overrun. In order that the physical model 4 fulfills its purpose and emulates the temperature of the glow plugs 3 as well as possible, in addition to the parallel control of the physical model 4, the additional positive or negative energy input can be mathematically added by external influences which deviate from the standard case.
- a correction module 13 is preferably provided, which lies between the physical model 4 and the control electronics 12 and the current engine condition, such as the speed, the torque, the injected fuel quantity, the temperature, etc., taken into account and the activation of the physical model 4 accordingly modified that the reference glow plug temperature output by the model closely matches the actual glow plug temperature.
- the control of the physical model 4 can be limited with a fixed value in the simplest case. It is known that during engine operation, glow plugs, at least in direct injection diesel engines, have a higher energy requirement than the low speed and very high load margins in order to maintain the setpoint temperature of the glow plugs. It is customary to form the control electronics 12 so that the power supply to the glow plugs is controlled so that the glow plug temperature is kept independent of the engine operating conditions. As a result, with the engine running and thus generally higher energy flow to the glow plugs than when the engine is assumed be that the glow plugs have exactly the target temperature.
- the correction module 13 can force the physical model 4 to a state corresponding to the setpoint temperature for these cases which are easy to detect.
- the additional positive or negative energy input may first be metrologically detected and in correlation with the engine control unit 1 or the glow control 2 available parameters such.
- the engine control unit 1 or the glow control 2 available parameters such as the speed, the internal torque, the air, engine, water or oil temperature are set.
- an algorithm or mathematical model is created and integrated into the correction module 13 so that it modifies the drive signal in parallel with the glow plug energization such that the physical model 4 follows the actual temperature at the glow plug.
- the temperature of the glow plugs can advantageously be regulated by producing a closed control loop by detecting the temperature of the physical model 4.
- a setpoint temperature sent, for example, from the engine control unit 1 to the glow control 2 can then be relatively easily implemented and monitored, wherein the achievement of this temperature can be fed back to the engine control unit 1.
- This scheme opens up further possibilities to bring the glow plugs 3 even faster than previously to the target temperature, since currently only lower heating rates are possible because of the lack of feedback of the resulting temperature at the glow plug 3.
