Definitions
- the invention relates to a method and a device to detect a switching time of a solenoid valve according to the preambles of the independent claims.
- a method and an apparatus for detecting a Switching time of a solenoid valve are, for example known from DE 44 25 987. There is a procedure described where the current flowing through the solenoid valve flows, is regulated to a predetermined value. By Evaluation of the controlled variable with which a switching device is applied, the current flow through the solenoid valve controls, the device determines the switching time. The device evaluates the effect that in Switching time changes the inductance of the solenoid valve.
- DE-OS 44 11 789 a method and a device for controlling the fuel metering in an internal combustion engine is known in which the injection in at least two partial injections is divided. With everyone Partial injection, the current is first at a tightening value and then regulated to a hold value.
- DE 196 07 073 describes a method and a device for detecting the switching time of a Solenoid valve known in which the current through the Solenoid valve in a tightening phase to a tightening value and is regulated to a hold value during a hold phase. The current is reduced to the second value before the solenoid valve reaches its end position, the detection of the Switching time takes place in the holding phase in which the Current is regulated to the hold value.
- the acquisition of the switching time takes place during the regulation to the holding value instead as during no saturation occurs during this holding phase, which is the Switching point detection impaired.
- the transition from The attraction value to the holding value occurs as shortly as possible the closing of the solenoid valve.
- the transition from that The tightening value on the holding value takes a certain amount of time increases, the greater the current difference between the is both current values. If the current difference is too large, so the transition time between the tightening value and the Hold value too large, and the switching time advantage of this GDP recording disappears.
- the switching time is in the first Approximation proportional to the time until the integral of the current reached a certain value over time. At a Switching earlier takes longer for the value of the Integral is reached.
- the invention is based, with one Method and device for detecting a Switching time of a solenoid valve of the aforementioned Kind of reliable detection of the switching time and to achieve a quick switching operation of the solenoid valve.
- the procedure according to the invention results in a reliable evaluation of the switching process and a faster Switching operation.
- FIG. 1 shows 2 shows a circuit of the device according to the invention, FIG. 2 various signals plotted over time and FIG. 3 the current curve plotted over time for a Injection with pre and main injection.
- FIG 100 is the coil of a solenoid valve drawn. This stands with its one connection with one Ubat supply voltage in connection. With her second Connection is via a switching means 110 and a Resistance means 120 connected to ground.
- the two Control connections of the two switching means 110 and 115 are from a control device 130 with control signals T1 and T2 applied.
- the control device 130 processes different signals from different sensors 135. Furthermore the control device evaluates the voltage drop Resistance means.
- the first and the second switching means are preferably as Transistors in particular as field effect transistors educated.
- Parallel to the coil of the solenoid valve 100 is one Series connection from the first path of a current mirror 140 and a first zener diode 145. It says the first connection of the current mirror 140 with the Supply voltage Ubat, and the cathode of the first Zener diode 145 stands with the connection point between the Coil 100 and first switching means 110 in connection.
- the second path of the current mirror 140 connects the Control connection of the first switching means 110 with the Connection point between the first Zener diode 145 and the first path of current mirror 140.
- a series connection of a diode 155 and a second zener diode 150 is a series connection of a diode 155 and a second zener diode 150.
- this connection stands the cathode of the diode 155 with the control connection of the Switching means 110 and the cathode of the second zener diode 150 with the cathode of the first Zener diode 145 and the Connection point between the coil 100 and the first Switching means 110 in contact.
- FIG 2 The mode of operation of this circuit is shown in FIG 2 signals described.
- the control signal T2 is for the second switching means 115 and in sub-figure 2c) Control signal T2 for the first switching means 110 applied.
- the voltage UD is at Connection point between coil 100 and the first switching means 110 applied.
- the two switching means are connected applied to such a signal that no current flows. This means that there is a voltage at point D that the Battery voltage corresponds to Ubat.
- the activation of the solenoid valve begins at time t1. From time t1, the two switching means 110 and 115 applied with such a signal that it the Enable current flow. This causes the voltage UD on Point D drops to 0. At the same time, the current IMV increases that flows through the coil and the current IT2 that flows through the second switching means 115 flows slowly.
- the current IMV which is generated by the Coil flows, the so-called tightening value. This value is so chosen that the solenoid valve as much energy as possible records and thus switches very quickly.
- the voltage increases UD slowly to a value that is almost the same Supply voltage corresponds to Ubat.
- the Value of current IT2 passing through second switching means 115 flows slowly.
- the switching means 110 is activated that it cuts off the flow of electricity. This does one Voltage rise in voltage UD due to inductance the coil 100. This has the consequence that the current IT2 very increases rapidly. Then the current that flows through the Coil 100 flows off. At the same time, the tension drops UD from. The total current flowing through the coil is from applied to the switching means 115.
- first switching means 110 is used as an analog current regulator operated. Depending on the comparison hiss between the desired and the flowing current becomes the switching means more or less controlled.
- control device To regulate the current to the various values the control device the voltage drop on Resistance means 120 out. Instead of the resistance agent 120 other suitable current measuring means can also be used become.
- the control device 130 gives depending on Operating state of the internal combustion engine by means of Sensors 135 are detected, different setpoints for the Current before. Depending on the comparison of the setpoint and the Actual value, which was detected by means of the current measuring means 130, the control device then controls the switching means 110 and 115 accordingly.
- the Zener diode 145 and the current mirror 140 cause that during the shutdown process the voltage UD due to the Inductance does not rise above a limit.
- the Current mirror regulates this voltage to one by means of the Zener diode 145 adjustable value.
- the Zener diode 150 and the diode 155 serve as a protective diode for the switching means 110, so at its control input there are no impermissible voltage values.
- FIG. 3 shows the particularly advantageous course of the current through the coil 100 for an injection that is in two Partial injections is shown. This Current flow is only shown schematically. The real one Current flow can also differ from the one shown.
- the course can also in other embodiments be modified. For example, it can also be provided his. That pre-current is also applied to the pre-injection takes place or that also with the main injection Detection value I3 is introduced. Can also be provided be that only one main injection with Detection value I3 and / or pre-energization value used becomes.
- Diesel engines are a small part of the amount of fuel to be injected before the actual one Main injection metered.
- the first partial injection is used as the pre-injection VE and the second partial injection referred to as the main injection HE.
- the Current In a starting phase P1V of the pre-injection VE, the Current from 0 to the pre-injection value. In the subsequent P2V acquisition phase The current is pre-injected to a detection value I3 governed. During this acquisition phase, the Switching point of GDP, which with a vertical arrow marked time occurs by a corresponding Evaluation of the current, the voltage or the control signal the switching means determined. The detection value is in the Detection phase P2V specified in which the switching time expected to occur.
- the detection phase P2V starts after the solenoid valve begins to move from one end position to the other move.
- the switching time is when the new end position defined. After reaching the new end position the acquisition phase P2V ends. This means during the Acquisition of the switching time, the current on the Detection value regulated, which is smaller than the tightening value and is greater than the hold value.
- the The current is pre-injected to the hold value I2 Pre-injection regulated.
- the deletion phase P4V pre-injection the quick extinguishing takes place during which the voltage at point UD by means of the Zener diode 145 and the current mirror 140 is regulated to a constant value becomes.
- the control is activated until the main injection HE begins interrupted.
- the tightening phase P1AH of the main injection there is a regulation on a so-called Pre-energization value I1.
- the subsequent Tightening phase P1AH of the main injection takes place Power up and, if necessary, the regulation on the Tightening value.
- the holding phase P3H the main injection is made the current is regulated to the hold value of the main injection.
- the holding phase P3H begins after the solenoid valve begins from one end position to the other end position move.
- the switching time of the main injection is detected.
- the extinguishing phase P4H of the main injection takes place Quick delete to the value 0.
- the detection value is chosen so that none Saturation symptoms occur.
- the detection value during the pre-injection chosen as low as possible.
- the pilot injection Tightening value in the pre-injection as high as possible Accept value. This results in a very large one Difference between the tightening value and the holding value.
- the difference is particularly important with pre-injection between the tightening value and the holding value I2 very large. It it takes a very long time until the current value from Tightening value passes to the holding value I2. This has to Consequence that the switching time advantage of this kind of Switching point detection disappears.
- an additional Current level which is referred to as detection value I3, is introduced, to which the current through the consumer 100 is regulated during the switching time of the solenoid valve is detected.
- This detection value I3 is according to the invention chosen so low that there are no signs of saturation occur. Furthermore, the detection value I3 becomes so high chosen that the difference between the tightening value and the Detection value 13 is as small as possible.
- a detection value is at Pre-injection is particularly advantageous. But it can also to be used for the main injection. In particular then if the difference between tightening value and holding value is very large.
- the holding value pre-injection is chosen to be significantly smaller than the holding value for the main injection. This can be ensured that the switching process at the end of Pre-injection VE done quickly.
- the Acquisition value I3 can also be smaller or larger values accept.
- the pre-energization value becomes like this chosen so that the solenoid valve does not respond. This can result in a quicker switch on Switching operation can be achieved.
