- the invention relates to a device and a method for controlling a drive unit, in particular a Internal combustion engine in a vehicle.
- DE 42 31 449 A1 discloses a device for controlling the drive power of an engine with at least two Control units proposed, with a first Control unit with a first group of measuring devices and a second control unit having a second group of Measuring devices of the same measuring element is connected.
- each Control unit or each processor must be the respective Functionality defined separately, realized, documented, tested and maintained. Likewise have to Both controllers or computers in development with equipped with expensive measuring means and / or emulation means become. Due to the asymmetrical definition of the Functional scope and thus the systems can, for example in the component assembly additional errors Confusion occur. At the same time one forces Further development or change of functionality in the existing system to consider both Control units or computers or their respective Functional scope, which is therefore very complex and very time and cost intensive.
- US 3875390 shows a control of a drive system in Form of turbines with two connected computers with are each connected to a plurality of sensors and actuators. These computers use in their program memories identical software to set the sensor values to control values to process their controllers.
- This system is as built completely redundant system what the program code, So the software as well as the functionalities are concerned, so that in particular in case of error, the overall function with respect the turbine control only executed by a computer can be. That the overall functionality lies in everyone Calculator completely in front of what a highly complex system leads with increased effort.
- control unit in particular an internal combustion engine, indicated with a control unit, wherein the control unit includes at least two computers.
- the control unit includes at least two computers.
- the program memory of the two computers or Computing units there contain the program code which both Calculator an identical possible range of functions exhibit.
- the individual functionalities are advantageously less complex than the necessary one Overall range of functions selectable, which nevertheless the complex overall functionality across all computers or Processors results.
- you use it is also largely go through the identical program code, but it can give individual parts, although in both memories or Computers are available but asymmetrical so only each be processed in or from a memory.
- the function distribution can be up more than two computers take place or there can be more Computer be present in the overall system, but one execute other program code, so other features exhibit.
- the computers can then conveniently in be housed different control devices.
- the two computers with identical possible functionality, for example via a serial or parallel bus system such as e.g. CAN or other serial Interfaces or a DPRAM, exchange information.
- a serial or parallel bus system such as e.g. CAN or other serial Interfaces or a DPRAM, exchange information.
- the program memory containing the Program code and thus contains the functionality advantageously just twice in the control unit equipped, which can not be confused.
- FIG. 1 shows an overview block diagram of a control unit with two computing elements or computers, which control at least one operating variable in the vehicle, preferably the power of a drive unit, in particular an internal combustion engine.
- FIG. 2 shows functional relationships of the two computers in the control unit and their surroundings.
- FIG. 3 shows the concrete embodiment in functional relationships with reference to a lambda control for the injection calculation in the internal combustion engine.
- FIG. 1 shows an electronic control unit 100 which at least two computers 101 and 102, an input module 103, an output module 104 and a bus system 105 includes.
- further components and / or Assemblies indicated by element 106 to the bus system 105th be coupled.
- These additional optional elements For example, additional memory elements and / or an additional bus input / output interface z. B. for diagnosis or connection of the control unit 100 with other controllers.
- the input module 103 can together with the output module 104 also as input / output module be summarized.
- the calculator 101 contains among other things a processor 109 and a the program memory 107 associated with this processor 109 program code stored in the program memory 107 corresponds to the possible scope of functions with respect to Control or regulation of the at least one operating variable how it can be processed by the processor 109. It is advantageous for the reasons mentioned above, if the first computer 101 and the second computer 102 also with a processor 110 and associated with it Program memory 108 are constructed completely identical. However, optionally different computers could be used as long as the possible range of functions both arithmetic units is identical.
- the input module 103 signals are supplied, which measured Operating variables of the drive unit, the drive train and / or of the vehicle or from which such farm sizes can be derived. Especially These are operating variables that are used to control a Internal combustion engine can be evaluated.
- the mentioned Signals are from measuring devices 111 to 113, in particular sensors, detected and via input lines 114 to 116 of the input module 103 supplied.
- the output module 104 Via the output module 104 are further signals issued which actuators or actuators for Setting at least one operating size of Drive unit, in particular the internal combustion engine, the Press vehicle.
- the corresponding signals for Actuation of the actuators 117 to 119 are on the Output lines 120 to 122 delivered.
- derived operating variables and / or internal sizes form the computer 101 and 102 in the frame there implemented programs values for the output Control variables that the control elements in the sense of set the prescribed control strategy.
- the control unit 100 is preferably a Control unit for controlling a drive unit, in particular an internal combustion engine, a vehicle is, for example, the position in a known manner detected by a driver operable control element, evaluated and a setpoint for a torque of Drive unit determined.
- This variety of programs is in the form of a program code in the respective program memories 107 and 108 of the computer filed or loadable there.
- the just described, by the programs or the program code in the program memory represented functional ranges of a control unit are in general very complex. That's why these are supposed to be complex Functional ranges of the control unit symmetrical at least two computers in the named controller be split.
- the computers can e.g. about one Communication system, in particular a bus system such as CAN or another serial or parallel interface or a memory element, in particular a DPRAM information change.
- the program memories 107 and 108 of the two Calculators 101 and 102 contain the same program code.
- the identical program code is also largely the same go through, but there are individual justified parts can, which are processed asymmetrically. For example through hardware lines and on these transmitted signals then the required unbalanced will be processed Programs or sections in the program code activated or disabled. For the sake of simplicity of illustration these line connections through the communication system 105 represented or integrated into this.
- the functional scope F1 controls in each case a cylinder bank with associated sensors and Actuatorics of the internal combustion engine. At the same time sensor sizes become such as an air / fuel ratio, cam or crankshaft position, knock information, air mass, etc. from the engine 200 to the computers 101 or 102, in particular their functional scope F1 delivered (205, 206). Control signals (204, 207) from the Functional ranges F1 in turn reach the Internal combustion engine or its actuator.
- the oriented ones Connections 204 to 207 provide the functionality the transmission itself.
- an adjuster e.g. a secondary air pump
- the corresponding output stage in the control unit only from one Computer
- the associated engine function e.g. Secondary air control including diagnostics, but runs symmetric in both computers and also provides sizes for further engine functions.
- actuators e.g. Secondary air valve, for a first cylinder bank, through the calculator for the other, second cylinder bank are operated, although the associated Engine function in the computer for the first cylinder bank is running.
- a tank system 201 is controlled by another feature F2 and supervised.
- This feature F2 is alike symmetrically contained in both computers 101 and 102. He However, for example, only by computer 101, ie processed asymmetrically. To do this, this function becomes F2 for example, by signals of separate hardware lines or by clear signals or data about the Communication system activated or deactivated. Consequently the diagnosis of the tank occurs when there is only one tank in the tank Vehicle exists only in a calculator.
- the corresponding Function F2 is on both computers in the program memory available, but it will only be activated on one page.
- the Communication relation between function F2 in computer 101 and the tank system 201 is through the connections 202 and 203 shown.
- Functional ranges F3 or F4 which on the one hand sensor elements 209 and 210 by means Communication connection 213 or 214 read in and be processed (F3).
- Actuators actuators 208 and 211 on the Communication links 212 and 215 through the Functional ranges F4 are operated.
- sizes too or other control systems such as a Traction control, a transmission control, etc. transmitted via the oriented connections 212 to 215 become.
- the functions F3 and F4 for example, also summarized as a function F34 to be viewed as.
- FIG 3 is a very specific embodiment of a 12-cylinder engine with concrete functionality shown.
- said 12-cylinder engine has 4 parallel exhaust lines with 4 control probes 310 to 313, combined as lambda probes 300.
- In the engine control would therefore have provided a so-called Quadrolambdargelung which are due to their high complexity in addition to the increased effort and risks related to malfunction, especially security risks.
- Quadrolambdargelung By the Symmetric division of functions on two computers is obtained in each computer 101 or 102 in the control unit 100 only a stereo lambda control so much less complex functionality.
- From the probes 310 to 313 supplied signals arrive via the interfaces 314 to 317 for hardware preparation.
- This signal conditioning is done for computer 101 by elements 308 and 309 for Calculator 102 through the elements 306 and 307.
- the Calculator 102, the probe signals US1 and US2 and the computer 101, the probe signals US3 and US4 are supplied.
