- the low-side line 135 is also connected to the load 250 and connected to the volume 260.
- the data line 240 only connects the Control unit 110 with the data carrier 260th
- the consumer 250 is in the illustrated embodiment as electromagnetic consumer, in particular designed as a solenoid valve.
- the procedure according to the invention is illustrated only with reference to a consumer.
- the procedure can also be transferred to several actuators. It can the actuator comprises one or more consumers. Consumers can do it be designed as a solenoid valve and / or as a piezoelectric actuator.
- each actuator is a low-side switch assigned.
- the actuator is preferably as an injector, the so-called Common rail systems is used, formed. The inventive But the procedure is not limited to such injectors, it can also with other actuators, such as in unit injectors are used.
- control unit provides drive 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 a releases certain time from a certain point in time.
- the data carrier is preferably designed so that it is readable and writable. That the control unit may describe the data carrier 260 with data and from the Read data carrier. It is preferably provided that the data carrier 260 is a Memory means and further elements, which for reading and / or describing the Memory are required.
- a Data line per actuator or a data line connecting all the actuators is provided.
- the control unit includes various functions. For example, an IMA procedure intended. In this process, the individual injection quantities of an injector at several test points. This test is carried out in Connection to the production of the injectors. The deviations of the respective injection quantities from the setpoint. This information is the injector provided with a suitable data carrier. There are several Possibilities known. The first time the controller is started up, the data becomes in a suitable form read into the controller and later in the process of control the internal combustion engine used. In this case, the injection quantity of the individual Injectors corrected by targeted change in the control duration of the injector, that it meters the desired amount of fuel to be injected.
- NMK which also as Zero quantity calibration
- the Activation determined, at the time just fuel is metered. This is provided that in each case to be checked injector in certain Operating conditions, especially in overrun operation, the driving time increases so long until an injection is detected based on a characteristic signal.
- the way determined zero quantity is also called the effective limit, from which the injected Fuel quantity triggers a perceptible in the speed signal torque formation.
- a quantity compensation scheme can be provided, which also serves as a MAR function referred to as.
- each cylinder is assigned a scheme that a variable characterizing the speed to a common setpoint for all Cylinder adjusts.
- Such a quantity compensation control often includes a regulator with integral part. The value of this integral part is characteristic of the Quantity error of the corresponding cylinder to which this controller is assigned.
- these integral parts of each controller are also 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, in particular the data of the zero-quantity calibration and the Megenaus GmbHsregelung and other procedures, the corresponding sizes, the individual actuators can be assigned to the disk 260th enrolled.
- the writing and reading of the data carrier takes place via an additional Data line 140.
- the data carrier is required next to the memory has additional functional units that communicate with the control unit can be guaranteed.
- the following must be Approach supported by the volume 260.
- the exchange of data takes place preferably in operating states in which no injection is possible since For example, the rail pressure is too low. Such a condition is for example the initialization of the controller and / or in the wake of drop in rail pressure before. In these cases, an injection is hydraulically excluded. Recognize the Control unit or the control unit that such a process is present, as follows proceed.
- both the high-side switch, as well as the low-side switch closed.
- This causes a current flow through the consumer 250, as he would also be done in the control of the consumer for injection. It is provided that the activation of at least one of the switching means, i. either of the High-side switch or the low-side switch, so short that the current flow can not cause injection, i. the control takes place so long that the Consumer does not respond to the energization. It is accordingly as in the Control only one actuator with a current pulse applied and thereby selected. This data flow recognizes the data carrier 260. After the successful Initialization of the disk, the low-side switch remains closed. Preferably the high-side switch is opened again.
- the data exchange takes place via the data line. Since all Injectors or a group of injectors for a common high-side switch are connected and the Injektorspulen have a low internal resistance are all low-side switches connected by short circuits. This does not make it possible Close an injector by closing a low-side switch in the controller. Out For this reason, the data communication is interrupted by a short current pulse at the corresponding injector started with active data line. A possible injection is At this time, it is undesirable and is replaced by at least one of two measures prevented. The measures are carried out individually and / or in combination. A The first measure is that the communication only in certain Operating conditions takes place. Furthermore, it is provided that the drive duration of the high-side switch so short that the activation is too short, that a reaction of the Actuator can be done.
- no communication is initialized during the injection, since here the data line is not supplied with a signal.
- FIG. 2a is the Switching state of the high-side switch
- Figure 2b the state of the low-side switch
- FIG. 2c the state of the data line 140 is plotted over time T.
- To the Time T1 is an operating state in which a data transfer is possible. From then on, both the high-side and the low-side switches will be turned on brought a conductive state. Furthermore, the data line is active. From the Time T2 will return the high-side switch to its non-conductive state brought. Due to the fact that between the time T1 and the time T2 both the High-side, as well as the low-side switches are in their closed state, flows in the short term, a current through the consumer 250. Starting from this current pulse recognizes the disk 260 that soon a data transfer takes place. These Detection preferably takes place when the data line, as is the case here, is active and the pulse is of a short duration.
- This state of the announced data transfer differs from the state of the Control of the consumer in that here the data line is active and that certain operating conditions exist. Together with the usual control, that the high-side and the low-side switches are actuated, i. 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 typically energized.
- the procedure of the invention was the example of a consumer who with equipped with a solenoid valve shown. It is per group of consumers just a high-side switch and a low-side switch for each consumer. Alternatively, it can also be provided that the function of the high-side switch and the Low-side switches are reversed. Furthermore, the procedure is also applicable, if only one switching means per consumer is provided.
- the procedure of the invention is not on actuators, the one Include solenoid valve, limited. It can also be used by other actuators, For example, be used in actuators that include a piezoelectric actuator.
