Description

Improvement of the operating parameters of a computing system in the vehicle

The present invention relates generally to computing systems in a vehicle. In particular, the present invention relates to a computer system for assigning tasks in the computer system and an associated method, wherein the computer system can be arranged in a vehicle.

Today's motor vehicles are equipped with several processors. More precisely, today's motor vehicles usually have one or more so-called ECUs (electronic control units). Such an ECU has one or more processors and other electronics in order to be able to perform specific tasks. These processors perform various tasks that are necessary to support or operate functions of the on-board network, the chassis, the chassis, the body, the comfort systems, the assistance systems and / or the entertainment systems of vehicles. These systems must be operable with a very high degree of robustness and fault tolerance. These systems must be fail-safe, particularly with regard to future autonomous driving. Accordingly, autonomous driving requires the provision of redundancy / redundancies in the vehicle, which is / are provided in today's solutions via additional hardware components. This increases the complexity and weight of today's structures.

As mentioned, for current and future functions in the vehicle, especially in the field of autonomous driving, the reliability of the computing systems required for this is of decisive importance. This means that the systems used must be designed to be fault-tolerant. Currently implemented architectures are optimized with a view to switching off an associated component in the event of an error (this is often referred to as fail-safe). Furthermore, current computer architectures for vehicles are essentially configured statically. The system monitoring of the computer architecture detects errors and starts a corresponding error program when they occur. For example, with the "AUTomotive Open System Architecture" (AUTOSAR) operating system that is often used nowadays for computer systems in vehicles, access to bus systems of the computer system is statically defined. Furthermore, certain tasks are statically assigned in the computer system Functions to be managed in the vehicle in the future, such as autonomous functions in general and autonomous driving In particular, significantly more powerful computing systems than have to be integrated into vehicles today. The complexity of these systems will hardly be manageable due to the currently used, static approaches. In addition, such static configurations are inflexible and, in particular, cannot be sufficiently adapted for future applications.

There is therefore a need for an improved, in particular flexible and / or adaptable, computer system for executing functions in a vehicle and for an associated method.

According to a first aspect of the invention, a computer system for assigning tasks in the computer system is proposed. The computer system can be arranged in a vehicle. The computer system has several interconnected computer components, several monitoring sensors, several system information components and several control components. In each case one of the monitoring sensors is arranged in one of the computer components and is designed to acquire information relevant to the computer system. In each case one of the system information components is stored in one of the computer components and has information about the computer system. One of the control components is stored in one of the computer components. The multiple control components are designed to communicate with one another. Furthermore, the multiple control components are designed to assign at least one task of the computer system to one or more of the computer components, taking into account the following information: the information about the computer system; the information relevant to the computer system detected by the plurality of monitoring sensors; and information specific to the vehicle.

In other words, the multiple control components are designed, at least one task of the computer system based on (i) the information about the computer system, (ii) the information relevant to the computer system recorded by the multiple monitoring sensors and (iii) the information specific to the vehicle to be assigned to one or more of the computer components.

In contrast to known computer systems, the computer system according to the first aspect is advantageous since there is no static assignment of tasks to computer components. In contrast, the computer system has control components that are designed to perform at least one task, taking into account the information about the computer system generated by the multiple monitoring sensors. to assign information relevant to the computer system and the information specific to the vehicle to one or more of the computer components. If the information recorded by the plurality of monitoring sensors and relevant for the computer system and / or the information specific to the vehicle change, for example, in such a way that a task of the at least one task should be carried out by one or more other of the plurality of computer components, the control component has the Task of one or more of the other of the several computer components. This flexible assignment, depending on the for. the vehicle-specific information and / or the information recorded by the plurality of monitoring sensors and relevant for the computer system provides a dynamic assignment of the tasks to be carried out. If the information specific to the vehicle is taken into account when assigning the task to be performed, the assignment is also improved, among other things, by the fact that not only information related to the computer system but also external information, more precisely the information specific to the vehicle, during the assignment must be taken into account. The computer system accordingly distributes the tasks to be carried out flexibly and / or dynamically. A dynamic optimization of the computer system is therefore provided. Furthermore, the described assignment enables an energy-optimized utilization of the computing system. The computer system can also assign or distribute tasks to one or more of the computer components in a forward-looking / predictive manner.

The information about the computer system can include information about the structure and / or the organization of the computer system. For example, information about the computer system can be information about the structure and / or the organization of the computer system. Accordingly, the plurality of control components can be designed to assign at least one task of the computer system to one or more of the computer components based on the information about the computer system and the information relevant to the computer system recorded by the plurality of monitoring sensors. In general, one of the terms “allocate”, “assign” or “allocate” can also be used instead of the term “assign”.

The information about the computer system can include information about at least one basic element for performing the at least one task of the computer system. The basic elements can, for example, be listed in the system information components with a unique identification. As examples of basic Selemente are here called controllers (control elements), filters, arithmetic units and logical units.

The computer system can also be referred to as a computer system. The computer system can be located in a vehicle. The computer system can be connected or connected to various components of the vehicle that are to be controlled or controllable. For example, the multiple computer components can be arranged in the vehicle. The one or more computer components can each have one or more processors, such as one or more ECUs.

The information relevant to the computer system is information that is relevant to the computer system. For example, it can be information about one or more operating parameters of the computer system and / or about one or more operating parameters of one or more of the computer components, such as information about energy consumption, bus load, utilization, memory consumption, temperature and / or Memory load of the computer system or one or more of the computer components.

The computer components can be connected to one another via a bus system. The computer components can communicate with one another via proprietary interfaces and bus systems. The computer system can be compatible with proprietary operating systems and operated by such operating systems. Additionally or alternatively, the computer system can be compatible with specified operating systems and operated by operating systems such as AUTOSAR.

The multiple control components can be designed to perform at least one task of the computer system exclusively taking into account (i) the information about the computer system, e.g. the information about the structure and / or the organization of the computer system, (ii) the information recorded by the multiple monitoring sensors for to assign the computer system-relevant information and (iii) the information specific to the vehicle to one or more of the computer components. In this case, no further information is taken into account for the dynamic assignment of the at least one task to the one or more computer components. The plurality of control components can be formed, a plurality of tasks of the computer system taking into account the information on the computer ^¬ system, for instance about the structure and / or organization of the computer system, the information detected by the plurality of monitoring sensors, for computing system-relevant information and for to assign the vehicle specific information to one or more of the computer components.

The multiplicity of tasks of the computer system can describe one or more functions that can be carried out by the computer system. In other words, a function to be carried out by the computer system can be formed by one or more tasks. The one or more functions can have or represent one or more functions that can be carried out in a motor vehicle. Examples of functions are control functions, closed control loops, data processing and filtering. The functions can be implemented using basic elements that are assigned to the corresponding tasks. The functions can be implemented with the help of actuators (also referred to as actuators) of the vehicle.

The computer system can be connectable to one or more vehicle sensors (sensors of the vehicle). Additionally or alternatively, the computer system can have one or more vehicle sensors. The one or more vehicle sensors can each be designed to record the information specific to the vehicle (also referred to as vehicle-specific information). The information specific to the vehicle can also be referred to as information about the vehicle. The information specific to the vehicle can be various detectable parameters of a vehicle, such as parameters of a drive unit of the vehicle, parameters of a brake unit of a vehicle, parameters of assistance systems of a vehicle, parameters of a chassis of a vehicle and other parameters of a vehicle. Specific examples of such information specific to the vehicle are also entries in a fault memory of one or more processors or components of the vehicle, problems on the vehicle bus or bus system of the vehicle or general hardware problems of the vehicle. A further example of such information specific to the vehicle is response times to subsystems / subsystems of the vehicle. For example, latencies / latency times of response times can be recorded and taken into account when redistributing software subsystems / subsystems, for example. The computer system can be connectable to one or more vehicle actuators (actuators of the vehicle). Additionally or alternatively, the computer system can have one or more vehicle actuators. The one or more vehicle actuators can each be designed to perform a function of the vehicle. The function of the vehicle can be various controllable and / or executable functions of a vehicle, such as functions of a drive unit of the vehicle, functions of a brake unit of the vehicle, functions of assistance systems of the vehicle, functions of a chassis of the vehicle and other functions of the vehicle .

The information about the computer system can contain information about which tasks and / or functions of the vehicle are controlled or carried out by which or which of the plurality of computer components. In other words, the information about the computer system can have information about an assignment of tasks and / or functions to the computer components and vice versa.

The plurality of control components can be designed to assign the at least one task of the computer system to one or more of the computer components, taking into account the information about the vehicle obtained from the one or more vehicle sensors.

In other words, the multiple control components can be designed to assign at least one task of the computer system based on, for example exclusively based on, the following information to one or more of the computer components: the information about the computer system, the information recorded by the multiple monitoring sensors, for the Computer system-relevant information and the one or more vehicle sensors detected / obtained information about the vehicle. As a result, the computer system can predictively assign or distribute tasks to one or more of the computer components.

An example of the information that is relevant for the computer system and recorded by the plurality of monitoring sensors is a hardware-related error in one of the computer components. Since the multiple control components assign the at least one task taking into account the hardware-related error that occurs, the at least one task can be reallocated before the error occurs. For example, will be fine before the hardware-side error (s) occurs, corresponding tasks and / or functions are allocated to other processors of the computer components.

An example of the information about the vehicle obtained from the one or more vehicle sensors is a hardware-related error that occurs in a component and / or function of the vehicle. Since the multiple control components assign the at least one task taking into account the hardware-related error that occurs, the at least one task can be reallocated before the error occurs. For example, before the hardware-related error (s) occurs, corresponding tasks and / or functions are allocated to other processors. For example, before the hardware-side error (s) occurs, corresponding tasks and / or functions are allocated to other processors of the computer components.

In addition or as an alternative to one on the hardware side, one or more other predictive causes can be taken into account, namely for example: Information about the energy, the temperature and / or the communication load of the computer components and / of the components or functions of the vehicle, and / of the availability of sensors and / or actuators. Thanks to the predictive assignment of tasks, interventions can be carried out before a problem occurs.

The control components can be designed to receive the information specific to the vehicle from at least one, for example all, of the one or more vehicle sensors. For example, the control components can be designed to select at least one of the one or more vehicle sensors for acquiring the information about the vehicle. For the selection of the one or more vehicle sensors, the control components can take into account the following information: the information about the computer system and / or the information relevant to the computer system and / or the information specific to the vehicle, such as that from the one or more vehicle sensors recorded / obtained information about the vehicle and / or information about the one or more vehicle sensors. For example, depending on the load and / or functionality of a vehicle sensor, one or more other vehicle sensors with corresponding or at least similar functionality can be selected. The control components can be designed to select at least one of the one or more vehicle actuators for executing the at least one task or a function containing the at least one task. For the selection of the one or more vehicle actuators, the control components can take into account the following information: the information about the computer system and / or the information about the computer system that is relevant to the computer system and / or the information specific to the vehicle, such as information about the one or more vehicle actuators. For example, depending on the utilization of a vehicle actuator, one or more other vehicle actuators with corresponding or at least similar functionality can be selected.

The control components can be designed to assign the at least one task of the computer system to the one or more of the computer components at predetermined, adaptable or regular time intervals or continuously. The control components can be designed to select the at least one of the one or more vehicle sensors for acquiring the information about the vehicle at predetermined, adaptable or regular time intervals or continuously. The control components can be designed to select the at least one of the one or more vehicle actuators for executing the at least one task or a function containing the at least one task at predetermined, adaptable or regular time intervals or continuously. The system information components can each be designed as an instance of an artificial deoxyribonucleic acid (DNA, from English deoxyribonucleic acid) of the computer system. Additionally or alternatively, the multiple control components can each be designed as an instance of an artificial hormone system of the computer system. The artificial DNA can describe or contain the construction, the structure and / or the organization of the computer system. The artificial DNA is stored in every computer component of the computer system.

The artificial DNA can describe basic elements including their identification as well as the tasks that can be carried out by the respective basic elements. The distribution / assignment of the tasks to the computer components takes place via the artificial hormone system depending on various artificial hormone values. The

Hormone levels can be mimicked through short messages that can be exchanged between the instances of the artificial hormone system. The artificial hormone values are used to determine suitable or the most suitable computational Finding components for a task, for example taking into account ability, load and task networking. The artificial hormone values can result from the information relevant to the computer system and / or the information specific to the vehicle, such as the information about the vehicle detected by the vehicle sensors, recorded by the plurality of monitoring sensors. The artificial hormone system can also use the artificial hormone values to find failed computer components and tasks.

For example, when the computer system is started, certain tasks are assigned to all basic elements depending on the available computing power of the computer components. These basic elements are then linked using the artificial DNA. The system therefore builds itself up in the best possible and most efficient way, depending on the available processor resources. In the event of a processor failure or any other significant change in the artificial hormone values, the basic elements are reassigned to other computer components and linked to these computer components if sufficient computing power is available. A function is not tied to one computer component, but can be divided between several computer components. The smallest indivisible unit is the task. A task cannot be distributed over several computer components. In the event of a processor failure, only the tasks and basic elements that were actually affected by the failure are reassigned. Furthermore, the basic elements can be assigned different meanings or priorities so that the most important tasks can be carried out if there is not enough computing power available to carry out all the tasks. On the other hand, unimportant functions can be deliberately switched off, e.g. in the event of an error. The number of processors required, e.g. ECUs, can thus be minimized. This reduces the hardware expenditure, the complexity and the weight of the system and / or leads to an optimization of costs. According to a second aspect, a method for assigning tasks in a computer system is provided. The computer system can be arranged in a vehicle. The computer system has several interconnected computer components, several monitoring sensors, several system information components and several control components. In each case one of the monitoring sensors is arranged in one of the computer components. One of each

System information components are stored in one of the computer components. In each case one of the system information components has information about the computer system. One of the control components is in each case in one of the computer components deposited. The multiple control components are designed to communicate with one another. The method includes detecting for the Rechnersys ^¬ tem relevant information by the plurality of monitoring sensors. The method further includes assigning, by the plurality of control components, at least one task of the computer system to one or more of the computer components, taking into account the following information: the information about the computer system; the information relevant to the computer system detected by the plurality of monitoring sensors; speci ^¬ for the vehicle fischer information.

A third aspect relates to a computer program with program code means that, when loaded into a computer or processor (e.g. a microprocessor, microcontroller or digital signal processor (DSP)), or on a computer or processor (e.g. a microprocessor, microcontroller or DSP) is running, causing the computer or processor (eg microprocessor, microcontroller or DSP) to carry out one or more steps or all steps of the method described above. ^{In addition, a program storage medium} or computer program product with the computer program mentioned is provided.

Further, the computer program may for instance be stored according to the third aspect, in the computer system of the first aspect and the Rechnersys ^¬ tem cause to effect a plurality or all of te the Aspek ^¬ previously described and / or steps of the method or of the second aspect.

A fourth aspect relates to a vehicle, for example a motor vehicle, with the computer system described herein.

Even if some of the aspects described above were described with respect to the computing ^¬ nersystem, so these aspects can also in a corresponding way in the vehicle, the method or the process implementing the computer program ^¬ be realized. In exactly the same way, the aspects described above in relation to the method can be implemented in the computer system or in the computer program implementing the method.

FIG. 1 schematically shows a computer system 10 for assigning tasks in the computer system 10. The computer system 10 can be arranged in a vehicle, for example a car. The computer system 10 has several interconnected computer components 20, 30, 40, several monitoring sensors 22, 32, 42, several system information components 24, 34, 44 and several control components 26, 36, 46. In each case one of the monitoring sensors 22, 32, 42 is arranged in one of the computer components 20, 30, 40 and is designed to acquire information relevant to the computer system 10. In each case one of the system information components 24, 34, 44 is stored in one of the computer components 20, 30, 40 and has information about the computer system 10. In each case one of the control components 26, 36, 46 is stored in one of the computer components 20, 30, 40. The plurality of control components 26, 36, 46 are designed to communicate with one another, for example via a bus system. The multiple control components 26, 36, 46 are designed to perform at least one task of the computer system 10 taking into account the information about the computer system 10, the information relevant to the computer system 10 and information specific to the vehicle detected by the multiple monitoring sensors 22, 32, 42 to be assigned to one or more of the computer components 20, 30, 40.

In the example from FIG. 1, the system information components 24, 34, 44 are each designed as an instance of an artificial DNA 24, 34, 44 of the computer system 10. In addition, in the example from FIG Instance of an artificial endocrine system 26, 36, 36 of the computer system 10 is formed. The artificial DNA 24, 34, 44 can describe or contain the construction, the structure and / or the organization of the computer system 10. The artificial DNA 24, 34, 44 is stored in each computer component 20, 30, 40 of the computer system 10. The artificial DNA 24, 34, 44 base elements can be described, together with their identification as well as the gene of the basic elements jeweili ^¬ executable task.

Figure 2 schematically shows a method of assigning tasks in a computing ^¬ nersystem. The computer system can be the computer system 10 from FIG. The method includes the acquisition of information relevant to the computer system 10 by the plurality of monitoring sensors 22, 32, 42 (step S202). The method further includes assigning, by the plurality of control components 26, 36, 46, to at least one task of the computer system 10, taking into account the information about the computer system 10, of the information relevant for the computer system 10 recorded by the plurality of monitoring sensors 22, 32, 42 and the information specific to the vehicle to one or more of the computer components 20, 30, 40 (step S204).

FIG. 3a schematically shows a computer system 10 for assigning tasks in the computer system 10 in normal operation. The computer system 10 from FIG. 3 a can be based on the computer system 10 from FIG. The corresponding components are therefore provided and designated with the same reference numerals. In addition, each of the computer components 22, 32, 42 has a computer platform 28, 38, 48 with which various tasks of the vehicle are controlled. The computer system 10 and consequently the computer components 20, 30, 40 are arranged in the vehicle.

The computer components 20, 30, 40 are each connected to vehicle sensors and / or vehicle actuators via suitable interfaces (denoted by I / O for input / output in FIG. 3a), which are denoted together with the reference numerals 50, 60, 70. Each of the components 50, 60, 70 can in principle be designed as a vehicle sensor and / or as a vehicle actuator.

Furthermore, three tasks 80a, 80b, 80c are shown in FIG. 3a, which exemplarily represent a large number of tasks that can be carried out by the computer components 20, 30, 40. The multiplicity of tasks of the computer system 10 can describe one or more functions that can be carried out by the computer system 10. In other words, a function to be carried out by the computer system 10 can on, be / will be formed by one or more tasks, for example one or more of the three tasks 80a, 80b, 80c. The one or more functions can have or represent one or more functions that can be carried out in a motor vehicle. Examples of functions are control functions, closed control loops, data processing functions and filter functions. The functions can be implemented using basic elements that are assigned to the corresponding tasks. A function is not divided to a computer ^¬ component 20, 30, 40 bound but can be applied to several computer components 20, 30, 40th The smallest indivisible unit is the task. A task cannot be distributed over several computer components.

In the example from FIG. 3 a, the system information components 24, 34, 44 are each designed as an instance of an artificial DNA of the computer system 10 briefly referred to as "DNA 24, 34, 44"). In addition, in the example from FIG artificial endocrine system or endocrine system instance 26, 36, 46 (the artificial endocrine system 26, 36, 46 is sometimes only referred to as “hormonal system 26, 36, 46” for short in the following). The artificial DNA 24, 34, 44 can describe or contain the construction, the structure and / or the organization of the computer system 10. The artificial DNA 24, 34, 44 is stored in each computer component 20, 30, 40 of the computer system 10. Furthermore, the DNA 24, 34, 44 in each computer component 20, 30, 40 is identical. The artificial DNA 24, 34, 44 can describe basic elements together with their identification as well as the tasks that can be carried out by the respective basic elements.

The tasks 80a, 80b, 80c are distributed / assigned to the computer components 20, 30, 40 via the artificial hormone system 26, 36, 46 as a function of various artificial hormone values. The artificial hormone system 26, 36, 36 is system-wide, ie it extends, so to speak, over all computer components 20, 30, 40. The hormone values can be imitated by short messages that can be exchanged between the instances of the artificial hormone system 26, 36, 46. The artificial hormone values are used to find suitable or the most suitable computer component 20, 30, 40 for a task, for example, taking into account ability, load and task management. networking. The artificial hormone values can differ depending on the computer component 20, 30, 40, ie assume different values in the computer components 20, 30, 40. The artificial hormone system 26, 36, 46 can also use the artificial hormone values to locate computer components 20, 30, 40 and tasks that have failed.

FIG. 3a shows normal operation of the computer system 10, for example when or after the computer system 10 is started. In normal operation, the basic elements are assigned certain tasks, for example depending on the available computing power of the computer components 20, 30, 40 24, 34, 44 linked. The computer system 10 accordingly builds itself up in the best possible and most efficient manner, for example as a function of the available processor resources.

The monitoring sensors 22, 32, 42 monitor and detect various Pa ^¬ parameters of the computer system 10. Rein may be mentioned at this point Tempe ^¬ ture, a load and / or memory usage of the computer system 10 as an example. Furthermore, the vehicle sensors 50, 60, 70 record vehicle-specific information / information about the vehicle. Purely by way of example, such information about the vehicle may be mentioned here as sensor data that support the vehicle in autonomous driving, for example data about neighboring vehicles, for example during an overtaking maneuver, or data about a braking maneuver or accelerating maneuver of the vehicle.

Taking into account the information obtained from the monitoring sensors 22, 32, 42, for example the available resources, and the information obtained from the vehicle sensors 50, 60, 70, the tasks 80a, 80c are assigned to the computer component 20 in the example from FIG the task 80b is assigned to the computer component 30. To carry out the tasks 80a, 80b, 80c and the functions formed by the tasks 80a, 80b, 80c, each of the computer components 20, 30, 40 can use corresponding ECUs of the vehicle. The respective ECUs can then the respective roles and functions of exporting ^¬ ren.

The computer system 10 now moves from normal operation from FIG. 3a into a state which deviates from normal operation. In the exemplary state from FIG. 3b, the monitoring sensor 22 detects a temperature overload of the computer component 20. The temperature overload can be determined, for example, in that recorded temperature values are compared with a predetermined temperature limit value and a temperature overload is determined when the temperature limit value is exceeded. The endocrine system entities 26, 36, 46 determine at regular time intervals or continuously whether one or more of the tasks 80a, 80b, 80c should / should be assigned to another computer component 20, 30, 40, ie whether one or more of the tasks 80a , 80b, 80c is / are to be redistributed. In the example from FIG. 3b, the instance of the hormonal system 26, taking into account the DNA 24 and the temperature overload detected by the monitoring sensor 22, determines to redistribute the task 80c from the computer component 20 to the computer component 40, ie now to assign the task 80c to the computer component 40.

A further example, not shown in FIG. 3b, would be a processor failure, e.g. one of the processors of the computer component 20 or a failure of the entire computer component 20 or a fault in a component of the vehicle or a failure of a component of the vehicle. The failure of the computer component 20 is shown by way of example in FIG. 3c. For the sake of clarity, the monitoring sensors 22, 32, 42 are not shown in FIG. 3c, but they can be arranged in the respective computer components 20, 30, 40 in accordance with FIGS. 3a and 3b.

In the exemplary case of a failure of the computer component 20 according to FIG. 3c, for example, both tasks 80a, 80c could be assigned to the computer component 40 taking into account the parameters mentioned (if sufficient computing power is available), or one task 80a of the computer component 30 and the other task 80c of the computer component 40 are assigned. The latter is illustrated by way of example in FIG. 3c. In the event of a processor error, only those tasks and basic elements are reassigned that were / are / will actually be influenced by the failure, i.e. only tasks 80a, 80c if the computer component 20 fails. The task 80b to be carried out on the computer component 30 is not reassigned / distributed. Furthermore, the basic elements can be assigned different meanings or priorities so that the most important tasks can be carried out if there is not enough computing power available to carry out all tasks.

The computer system 10 essentially corresponds to the computer system 10 from FIGS. 3a to 3c. In contrast to Figures 3a to 3c, in Figure 3d the driving Vehicle sensors and vehicle actuators are not each shown together and accordingly are not each designated with a common reference number 50, 60, 70. By contrast, shown in FIG 3d shows an alternative form of the arrangement and Ver ^¬ compound of the vehicle sensors 50, 70 (are shown in Figure 3d only the first vehicle sensor 50 and the last vehicle sensor 70 of the plurality of vehicle sensors 50, provides 70 Darge ^¬) and the vehicle actuators 52, 72 ( In Figure 3d only the first vehicle actuator 52 and the last vehicle actuator 72 of the plurality of vehicle actuators 52, 72 are shown), the vehicle sensors 50, 70 and the vehicle actuators 52, 72 being arranged separately from one another by way of example and via separate bus systems / bus connections with the computer components 20, 30, 40 are connected and are accordingly provided with different reference numerals. Corresponds to the grundsätzli ^¬ che functionality, except for the different driving of the vehicle sensors 50, 70 and vehicle actuators 52, 72 in comparison with those of Figures 3a to 3c, the functionality described above with respect to Figures 1 through 3c.

Another example, not explicitly shown in FIGS. 3a to 3d, would be if, in addition or as an alternative to the detection of a temperature overload of the computer component 20, the vehicle sensor 50, for example, detects information about the vehicle, such as data received from a braking device of the vehicle. These data can specify, for example, a brake pressure desired by the driver of the vehicle. The information about the vehicle detected by the vehicle sensor 50 can then be passed on accordingly to the computer components 20, 30, 40, in particular the respective instance of the endocrine system 26, 36, 46.

According to this example, not only taking into account the DNA 24 and the temperature overload detected by the monitoring sensor 22, the entity of the hormonal system 26 determines to redistribute the task 80c from the computer component 20 to the computer component 40, ie now to assign the task 80c to the computer component 40. In addition, the information recorded by the vehicle sensor 50 is also included in the decision of the entity of the hormone system 26. For example, it can be the case that task 80b could be distributed both to computer component 30 and to computer component 40, or even would be distributed to computer component 30, only taking into account the detected temperature overload. However, the entity of the endocrine system 26 also takes into account the information detected by the vehicle sensor 50, that is to say, in the example mentioned, information about a braking process. For example, controls are used by Tasks relating to braking processes are carried out, among other things, on the computer component 30 (possibly also by other of the computer components 20, 30, 40). The instance of the endocrine system 26 is aware of this due to its ability to access the DNA 24. The entity of the endocrine system 26 can therefore foresee / predict that the computer component 30 will soon or in the future be busy controlling the tasks of a braking process. The instance of the endocrine system 26 will therefore assign the task 80b not to the computer component 30 but to the computer component 40. A specific exemplary embodiment of the computer system 10 is shown by way of example in FIG. For the sake of clarity, both the monitoring sensors 22, 32, 42 and the artificial DNA 24, 34, 44 are not shown in FIG. The monitoring sensors 22, 32, 42 and the artificial DNA 24, 34, 44 can, however, be arranged in the computer components 20, 30, 40 in accordance with FIGS. 3a to 3d.

In FIG. 4, the computer system 10 is used, for example, to control a steering system and a brake of a vehicle. Accordingly, sensors and actuators of a steering system and sensors and actuators of a brake are shown as vehicle sensors and vehicle actuators. These are shown in simplified form in FIG. 4 together as steering motor 50 and brake motor 70. Sensors and / or actuators of a steering system can be present in the steering motor 50. Sensors and / or actuators of a brake can be present in the brake motor. The functionality of the computer system 10 from FIG. 4 corresponds to the functionality as described in relation to FIGS. 1 to 3d. Purely by way of example, the computer component 20 in FIG. 4 is responsible for steering the vehicle. Furthermore, purely by way of example in FIG. 4, computer component 30 is responsible for the brakes of the vehicle. The computer component 40 is not used for any function purely by way of example and can be reserved for further functions for controlling the vehicle. Although the computer component 20 is only responsible for steering the vehicle by way of example, it can furthermore also be connected to the brake motor 70 via a bus system in order to receive information about the brake motor 70 therefrom. The computer component 30 is, for example, connected both to the steering motor 50 and to the brake motor 70 and in this way can receive information about the steering motor 50 and information about the brake motor directly from them. According to the example from FIG. 4, the instance of the hormonal system 26 of the computer component 20 determines how the tasks 80a, 80b, 80c are to be distributed / assigned, not only taking into account the DNA 24 and the information recorded by the monitoring sensor 22. In addition, in the decision of the instance go of the endocrine system 26 also by a sensor of the steering motor 50 detected information and / or detected by a sensor of the brake motor 70 Informa ^¬ a tions. On the basis of the information, the computer component 20 can, for example, control / execute tasks 80a, 80c assigned to it relating to a steering process and control one or more actuators of the steering motor accordingly. Furthermore, according to the example from FIG. 4, the instance of the hormonal system 36 of the computer component 30 determines how the tasks 80a, 80b, 80c are to be distributed / assigned, not only taking into account the DNA 34 and the information recorded by the monitoring sensor 32. In addition, the information captured by a sensor of the steering motor 50 and / or the information captured by a sensor of the brake motor 70 also go into the decision of the entity of the hormonal system 36. Based on the information, the computer component 30 can, for example, control / execute the task 80b assigned to it relating to a braking process and control one or more actuators of the brake motor 70 accordingly.

With the described computer system 10 according to FIGS. 1, 3a to 3d and 4 and the method from FIG. 2, the computer system 10 is predictively brought into the current best state. This avoids misconduct in advance. To this end, corresponding system variables such as processor performance, temperature or the like are monitored and the computing system 10 is reconfigured if necessary. Parameters of the vehicle in which the computing system 10 is arranged also flow into the decisions of the computing system 10. In addition, the computing system 10 can be optimized in other directions, for example with regard to energy consumption.

A predictive optimization of the computer system of a vehicle can be achieved by means of the proposed computing system and method. Furthermore, the robustness (fault tolerance) of the computing system is improved. Further optimizations, such as minimizing energy consumption, are possible. By applying organizational principles from biology, various (self-X) system properties (self-X) are obtained, such as self-organization (expression of the system according to the current system state), self-configuration (independent initialization), self-optimization (ongoing optimization of the system based on the current System states) and self-healing (high fault tolerance due to the possibility of reorganizing the system).
