- the consumer 250 is in the illustrated embodiment as electromagnetic consumer, especially designed as a solenoid valve.
- the procedure according to the invention is shown only on the basis of a consumer.
- the procedure can also be transferred to several actuators. It can the actuator comprises one or more consumers.
- the consumer can do it be designed as a solenoid valve and / or as a piezo actuator.
- each actuator has a low-side switch assigned.
- the actuator is preferably an injector, the so-called Common rail systems are used, trained.
- the procedure is not limited to such injectors, it can also be used other actuators, such as pump-nozzle units, can be used.
- control unit provides control signals with which the high-side switch and / or the low-side switch are operated in such a way that the consumer is energized accordingly and the fuel metering for one releases a certain period of time from a certain point in time.
- the data carrier is preferably designed such that it is readable and writable. That the control unit can write data to the data carrier 260 and from that Read data carrier. It is preferably provided that the data carrier 260 is on Includes storage means and other elements for reading and / or writing the Memory are required.
- a Data line per actuator or one data line that connects all actuators is provided.
- the control unit contains various functions. This is, for example, an IMA procedure intended. With this method, the individual injection quantities of an injector at several test points. This test takes place in the Connection to the manufacture of the injectors. The deviations of the respective injection quantities from the setpoint. This information is sent to the injector given by means of a suitable data carrier. There are several Possibilities known. When the control unit is started up for the first time, the data read into the control unit in a suitable form and later for control purposes the internal combustion engine used. The injection quantity of the individual Corrected injectors by deliberately changing the control duration of the injector, that this measures the desired amount of fuel to be injected.
- NMK which is also known as Zero quantity calibration.
- the zero quantity determined is also referred to as the effective limit from which the injected one Fuel quantity triggers a torque formation perceptible in the speed signal.
- a quantity compensation regulation can also be provided, which also functions as a MAR function referred to as.
- a control is assigned to each cylinder, which a variable characterizing the speed to a common setpoint for all Cylinder adjusts.
- Such a quantity compensation regulation often includes a controller with integral part. The value of this integral component is characteristic of the Quantity error of the corresponding cylinder to which this controller is assigned. This is why these integral components of the individual controllers are usually also shown in stored in a non-volatile, rewritable memory.
- the data, the individual cylinders or Injectors can be assigned and usually in a non-volatile and / or rewritable memory are stored in the control unit, alternatively and / or additionally stored in the data carrier 260 of the respective actuator. That is, especially the data of the zero quantity calibration and the Equalization scheme and other procedures, the corresponding sizes, the Individual actuators can be assigned to the data carrier 260 enrolled.
- Control unit that ensures data integrity without additional measures and Means such as diagnostic testers must be provided.
- All data can be read and written as data carriers writable memory elements, in particular EEPROM memory can be used. This ensures that all functions, the individual data of the actuator can use. All adaptive algorithms, the data on the individual Determine actuators and save them in an optimal way for logistics perform a service-friendly manner.
- the data carrier is written and read via an additional one Data line 140.
- the data carrier also needs for reading in and reading out the data the memory still additional functional units with which the communication with the control unit can be guaranteed.
- the following must Procedure supported by the data carrier 260.
- the exchange of data preferably takes place in operating states in which no injection is possible, since for example, the rail pressure is too low. Such a condition is included, for example the initialization of the control unit and / or afterwards after the rail pressure has dropped. In these cases, an injection is hydraulically excluded. Recognize that Control unit or the control device that such a process is present is as follows proceed.
- both the high-side switch and the low-side switch closed. This causes current to flow through consumer 250 as it is would also take place when the consumer is controlled for injection. It is provided that the control of at least one of the switching means, i.e. either of High-side switch or the low-side switch, so short that the current flow cannot cause injection, i.e. the control takes so long that the Consumers do not respond to the current supply. It is corresponding to the Actuating only one actuator with a current pulse and thereby selected.
- the data carrier 260 recognizes this current flow
- the low-side switch remains closed when the data carrier is initialized. Preferably the high-side switch is opened again. From the time the high-side switch is closed, the data exchange takes place via the data line.
- a first measure is that communication is only in certain Operating states. Furthermore, it is provided that the activation time of the high-side switch is so short that the control is too short that a reaction of the Actuator can take place.
- No communication is preferably initialized during the injection, since here no signal is applied to the data line.
- FIG. 2a A corresponding signal curve is shown as an example in FIG. 2.
- Figure 2a is the Switching state of the high-side switch
- Figure 2b the state of the low-side switch and the state of the data line 140 is plotted against the time T in FIG. 2c.
- To the Time T1 is an operating state in which data transmission is possible. From this point on, both the high-side switch and the low-side switch are switched on brought a conductive state. The data line is also active. From the At time T2, the high-side switch returns to its non-conductive state brought.
- the data carrier 260 recognizes that a data transmission will take place soon. This Detection preferably takes place when the data line, as is the case here, is active and the pulse is of short duration.
- This state of the announced data transmission differs from the state of Actuation of the consumer in that the data line is active here and that certain operating conditions exist.
- the high-side and low-side switches operate, i.e. are in the conductive state. This is also the case with the usual control. That by pressing the high-side switch and the low-side switch, the consumer 250 is usually energized.
- the procedure according to the invention was based on the example of a consumer who is equipped with a solenoid valve. It is per group of consumers only one high-side switch and one low-side switch for each consumer. Alternatively, it can also be provided that the function of the high-side switch and the Low-side switch are reversed. The procedure is also applicable if only one switching means per consumer is provided.
- actuators Include solenoid valve, limited. It can also be used with other actuators, can be used, for example, in actuators that comprise a piezo actuator.
