Definitions
- Engine controller for an internal combustion engine with collective adjustment for engine operating parameters
- the invention relates to an engine control unit for an internal combustion engine, in particular a drive internal combustion engine, of a fleet vehicle in a vehicle fleet with at least two, i.e. two or more fleet vehicles, which has a control unit for setting control variables based on measured variables according to a value stored in the engine control unit control scheme has.
- Modern engine controllers in vehicle internal combustion engines control or regulate the internal combustion engine based on a control scheme.
- This control scheme which can be in the form of a high-dimensional map for the engine operating parameters (or, more generally, with such an operating parameter map), corresponds to a mathematical mapping of a number of measured variables, which are also referred to as input engine operating parameters can be, on a number of controlled variables, which can be referred to as output engine operating parameters.
- the control variables are typically output by the corresponding control unit of the engine control unit as a voltage, with both the level of the corresponding voltage and the time of application, the "timing", of the corresponding voltage determining the corresponding control variables.
- the ignition point as an output engine operating parameter is usually set via the timing of the corresponding voltage, i.e.
- the exact point in time of a corresponding voltage peak in the associated control channel, with the point in time being Relative point in time based on a working cycle of the internal combustion engine can be specified, for example based on a top dead center coded digital signal, for example as a data signal from corresponding sensors or as a data signal which contains calculated values from a corresponding arithmetic unit based on corresponding sensor values.
- the control scheme for example in the form of a multidimensional operating parameter map, then maps a higher-dimensional measured variable space of, for example, nine dimensions to a lower-dimensional controlled variable space of, for example, three dimensions.
- the ideal control scheme for an internal combustion engine also generally depends on factors that are not or are not explicitly considered in the control scheme. For example, fuel quality, air pressure, humidity, ambient temperature or other environmental parameters, which can vary during operation of the internal combustion engine and are often not foreseeable when the engine control unit is designed, also change the behavior of the internal combustion engine.
- a universal control scheme is accordingly stored in the engine control units, which produces stable, acceptable results for different environmental parameters, ie varying, different values of one or more environmental parameters, for example with regard to a torque response, a fuel Consumption or an exhaust gas composition of the internal combustion engine supplies.
- a torque response here describes the course of a provided actual torque of the internal combustion engine in response to a requested target torque.
- a fleet vehicle is a vehicle in a vehicle fleet with at least two, preferably more than two, in particular a large number of vehicles.
- the engine control unit has a control unit which is designed to set control variables based on measured variables in accordance with a control scheme stored in the engine control unit, in particular in the control unit.
- the control scheme is a mapping of the measured variables to the controlled variables, which describes a control response of the control unit.
- the control scheme can correspondingly include or be a characteristic map, a so-called operating parameter characteristic map.
- Such a characteristic map is generally high-dimensional, ie it can have three or more, six or more, nine or more, twelve or more dimensions, for example.
- disclosure can also be understood as setting in the sense of controlling or regulating.
- the engine control unit also has a data interface unit which is designed to transmit, i.e. send and/or receive, respective engine operating data records to or from another engine control unit of a respective internal combustion engine of at least one other fleet vehicle.
- the data interface unit can therefore, directly or indirectly, transmit engine operating data records of its own engine control unit to one or more engine control units of other fleet vehicles.
- its own engine control unit can also receive respective engine operating data records from one or more other respective fleet vehicles, either directly or indirectly.
- the control unit is designed to set the control variables taking into account, in particular based on, at least one engine operating data record of the other engine control unit received via the data interface unit.
- the control unit can consequently compare the received engine operating data sets with its own corresponding operating data, i.e.
- the predefined criterion can, for example, represent a predefined reliability, for example whether there is sufficient historical experience for the current operating point of one's own internal combustion engine or a predefined number of engine operating data sets that are sufficiently similar according to the criterion.
- an engine control unit of a fleet vehicle which is generally used at low altitudes above zero and thus at comparatively high air pressure, can be used when driving in the mountains, where in At higher operating altitudes above sea level, the air pressure also decreases and the internal combustion engine thus exhibits operating behavior that differs from normal operation at lower altitudes, access an engine operating data set from another engine control unit that is used in this environment, ie in this case with reduced air pressure, and has therefore been tested.
- the control scheme can thus be optimized, for example, with regard to a predefined optimization parameter such as a torque response, fuel consumption, or an exhaust gas composition.
- the engine operating data sets contain at least one measured variable and/or at least one controlled variable and/or at least one control scheme and/or at least one environment parameter characterizing an environment of the engine control unit and/or an optimization as the respective operating data -Parameter that evaluates a control scheme, in particular a partial aspect of a control scheme, such as a section of an operating parameter map.
- the respective operating data can in each case be time-dependent operating data, ie stored in a chronological sequence and/or correlated.
- the measured variables described here and above can in particular be an engine speed and/or a throttle valve position and/or an injection spray quantity and/or a combustion residual gas quantity and/or an ignition point and/or a valve opening point and valve closing point and/or an engine temperature and/or or an intake-side gas mixture pressure (in particular from the previous working cycle) and/or a pressure in the combustion chamber (in particular from the previous working cycle) and/or an exhaust-side gas mixture pressure (in particular from the previous working cycle) and/or an engine torque and / or include an engine mileage.
- control variables mentioned here and above can, in particular, be a throttle valve position and/or an injection quantity and/or an ignition time and/or a valve opening time and valve closing time (a phase adjuster for the valves) and/or a turbocharger supercharging pressure.
- control scheme described here and above may be or include an operating parameter map.
- a corresponding section of the control scheme can be a section of the operating parameter map.
- the environmental parameters described here and above can in particular include a geographic position of the vehicle, preferably with a geographic elevation, and/or an engine ambient air pressure and/or an engine ambient humidity and/or an engine ambient temperature and/or a fuel quality and/or an internal combustion engine type designation and/or a fleet vehicle type designation and/or a fleet vehicle mass, ie a mass of the fleet vehicle belonging to the respective engine control unit from which the engine operating data sets originate.
- the operating data mentioned have proven to be particularly advantageous in each case.
- the data interface unit comprises or is a wireless fleet vehicle-to-fleet vehicle data interface unit.
- a fleet vehicle-to-fleet vehicle data interface unit can also be referred to as a car-to-car data interface unit.
- the data interface unit can have a transmission-related limited range which (in particular under real usage conditions) is less than 10 km or less than 5 km or less than 2 km or less than 1 km.
- the data interface unit may be or include a wireless local area network (WLAN) data interface unit or be or include a near-field radio (e.g., Bluetooth, BT) data interface unit.
- WLAN wireless local area network
- BT near-field radio
- engine operating data sets can only be exchanged in the environment of the fleet vehicle belonging to the engine control unit, which is predetermined by the limited range.
- This has the advantage that information about the environment of the engine control unit, which influences the behavior of the internal combustion engine, is transmitted implicitly, ie not explicitly Detected environment parameters, which do not change or hardly change in a sufficiently small environment of the fleet vehicle, are taken into account.
- many parameters such as air pressure, air humidity or ambient temperature are generally at least similar.
- one's own engine control unit can achieve optimized control particularly quickly, ie ensure ideal operating conditions for the internal combustion engine controlled by one's own engine control unit.
- the data interface unit includes or is a wireless fleet vehicle-to-fleet server data interface unit.
- a fleet vehicle-to-fleet server data interface unit can also be referred to as a car-to-car server or car-to-infrastructure data interface unit.
- the data interface unit is accordingly designed to transmit the engine operating data sets via a fleet server to one or more respective other engine control units.
- this can be a mobile radio (in particular LTE or 5G) data interface unit.
- engine operating data sets can also be made available which, in the further past, have provided suitable results, ie results which can be used advantageously for controlling one's own internal combustion engine.
- an engine operating data record from the engine's own engine control unit can also be used, which was used and tested in the same environment but at a different time, for example the day before.
- This is advantageous in that many environmental parameters such as air pressure at the same location often change on different days resemble
- the number of available engine operating data sets can also be increased, so that a particularly large number of different engine operating data sets can also be made available via the fleet server, and the probability that a particularly suitable engine operating data set will be found is therefore increased. This is also described in more detail below in connection with the memory unit.
- the engine control unit has a memory unit which is designed to store different engine operating data records of one or more other engine control units transmitted at different times and/or from engine control units of different other fleet vehicles.
- the transmitted engine operating data sets can be transmitted directly, i.e. directly from another engine control unit, or indirectly, i.e. via the fleet server described, from engine control unit to engine control unit.
- the storage unit can also be configured in the fleet server.
- the engine control unit or, correspondingly, the fleet server also has a selection unit which is designed to select at least one engine operating data set from the engine operating data sets stored in the memory unit, based on which the control unit sets the control variables, or to decide that the control variables are based can be set to their own measured variables according to the control scheme stored in the engine control unit.
- the stored engine operating data sets include at least one environment parameter and other engine operating data, in particular a control scheme
- the selection unit is designed to evaluate the at least one environment parameter of the stored operating data sets with a corresponding the engine control unit locally, i.e. on or in the assigned To compare vehicle detected environment parameters and based on a comparison result from the stored engine operating data sets to select the engine operating data set and thus those engine operating data, based on which or which the control unit adjusts the control variables.
- the stored engine operating data sets each include at least one optimization parameter, as will be introduced further below, and further engine operating data, in particular a control scheme, and the selection unit is designed to use the at least one optimization To compare parameters of the stored engine operating data sets with a corresponding optimization parameter that can be derived locally by the engine control unit for the own control scheme already stored in the control unit and based on a comparison result from the stored engine operating data sets to select the engine operating data set and thus those engine operating data , based on which the control unit adjusts the initial engine operating parameters.
- the selection unit is designed to select an engine operating data set for setting the control variables by the control unit, for which the comparison result shows the smallest deviation from the environment parameter recorded locally by the engine control unit and/or the greatest improvement compared to the optimization parameter(s) determined by the engine control unit for its own operating data. This has the advantage that in the given situation the engine operating parameters of the most similar environment or with the best control properties are selected for the engine control unit.
- a generation unit is present, which is in particular part of the selection unit and which is formed to generate at least one meta engine operating data set from the engine operating data sets stored in the memory unit.
- the engine operating data sets on which the meta engine operating data set is based can come from a number of different engine control units or from the same engine control unit at different times.
- the engine operating data sets on which a respective meta-engine operating data set is based preferably each comprise at least one environment parameter and/or one optimization parameter, which differ from one another in terms of their value by less than a predefined limit value. Engine operating data sets from similar environments and/or similar optimization quality are thus combined to form a meta engine operating data set.
- the different engine operating data records can be transferred to the meta engine operating data record by averaging the values of the respective parameters. This has the advantage that greater stability and thus increased reliability of the engine control unit under the different conditions is also achieved when using engine operating data records originating from other engine control units.
- the generation unit generates the at least one meta engine operating data set using machine learning from the stored engine operating data sets.
- the machine learning optimizes in particular a predetermined optimization parameter already referenced above, which can be or include, for example, a torque response of the internal combustion engine and/or a fuel consumption of the internal combustion engine and/or an exhaust gas composition of the internal combustion engine, according to an optimization specification.
- a predetermined optimization parameter already referenced above, which can be or include, for example, a torque response of the internal combustion engine and/or a fuel consumption of the internal combustion engine and/or an exhaust gas composition of the internal combustion engine, according to an optimization specification.
- This has the advantage that a particularly flexible and adaptable engine control for the internal combustion engine is achieved.
- the methods of machine learning are particularly advantageous here, since a large amount of operating data is available as a basis for learning.
- the machine learning can take place in real time, i.e. during the control time, as well as in advance after the availability of the data on which the learning is based.
- the learning can also be designed to be switchable between “learning in real time” and “learning in advance”.
- the generating unit described in the last paragraphs can also be implemented in a fleet server of an engine control unit system.
- the engine control unit system has at least two engine control units according to one of the described embodiments and a fleet server, which is designed to transmit the engine operating data between the at least two engine control units and includes a memory unit, which is designed to store transmitted engine operating data sets .
- a further aspect relates to an engine control system with at least two engine control units according to one of the specified embodiments and a fleet server which is designed to transmit the engine operating data between the at least two engine control units.
- a further aspect relates to a motor vehicle with an engine control unit according to one of the described embodiments.
- Yet another aspect relates to a method for operating an engine control unit of an internal combustion engine of a fleet vehicle in a vehicle fleet with at least two fleet vehicles, which includes the method step of transmitting engine operating data sets from one engine control unit to at least one other engine control unit of an internal combustion engine of a respective other fleet vehicle via a data interface unit.
- Advantages and advantageous embodiments of this method correspond here to the advantages and advantageous embodiments described for the engine control device.
- a final aspect relates to a method for operating an engine control unit of an internal combustion engine of a fleet vehicle in a vehicle fleet with at least two fleet vehicles with the following method steps: transmission of at least one engine operating data record from at least one other engine control unit of an internal combustion engine of a respective other fleet vehicle to your own engine control unit via a data interface unit; Setting control variables of the engine control unit, taking into account at least one of the engine operating data records received via the data interface unit from the engine control unit of the at least one other engine control unit.
- FIG. 1 shows respective engine control devices 1, 1' in respective fleet vehicles 2, 2' which have a respective internal combustion engine (not shown) controlled by the corresponding engine control device 1, 1'.
- Each of the engine control units 1, 1' has a control unit 3, 3' which is designed to control the respectively associated internal combustion engine. This is done by setting the respective control variables based on measured variables according to a control scheme stored in the engine control unit 1, 1', for example the control unit 3, 3'.
- the control scheme can be stored, for example, in the form of a multidimensional characteristic map.
- the engine control units 1, 1' have a respective data interface unit 4, 4', which is designed to transmit respective engine operating data sets to or from another engine control unit 1', 1 of another fleet vehicle 2', 2 .
- the engine operating data sets can include all or part of the specified control variables and/or the specified measured variables and/or the specified control schemes.
- the engine operating data records can also additionally include corresponding environment parameters or optimization parameters.
- Both control units 3, 3' are designed to set the controlled variable taking into account at least one engine operating data record of the other engine control unit(s) 1', 1 received via the data interface unit 4, 4'.
- the respective data interface units 4, 4' are both wireless fleet vehicle-to-fleet vehicle data interface units and wireless fleet vehicle-to-fleet server data interface units.
- the two engine control devices 1, 1' can transmit or exchange engine operating data sets directly via a radio connection 5, for example a wireless local area network connection (Wireless Local Area Network, WLAN), as well as via respective mobile radio connections 6, 6'. indirectly via a fleet server 7, for example a cloud, which transmit the corresponding engine operating data sets.
- a radio connection 5 for example a wireless local area network connection (Wireless Local Area Network, WLAN)
- WLAN wireless Local Area Network
- a fleet server 7 for example a cloud, which transmit the corresponding engine operating data sets.
- the direct exchange via the wireless network connection 5 has the advantage part that the engine control units 1, 1 'can adjust their control comparatively easily.
- the first fleet vehicle 2, which is currently still traveling in a low-lying lake landscape with higher air pressure can therefore rely on operating the internal combustion engine under high load in a higher environment with lower air pressure, as the second fleet vehicle 2' has to cope with at the moment , set.
- the engine control unit 1' of the second fleet vehicle 2' can already be adjusted to the operation of the internal combustion engine in the low-lying lake landscape with greater air pressure.
- the fleet server 7 has a memory unit 8, which is designed to store different transmitted engine operating data records from one or more engine control units 1, 1'.
- the fleet server 7 also has a selection unit 9, which is designed to select at least one engine operating data set from the engine operating data sets stored in the storage unit, based on which the corresponding control unit 1, 1' should then set the controlled variable.
- the stored engine operating data sets present at least one environment parameter to the engine operating data sets a respective environment, present the environment 10 or 10 'of the vehicles 2, 2', namely the high air pressure environment 10 and the low air pressure environment 10' to be assigned.

- the environment parameter associated with the stored engine operating data sets can be compared with an environment parameter recorded by the respective engine control unit 1, 1' and transmitted to the fleet server 7, for example. parameters are compared.
- an engine operating data set can be selected for the first fleet vehicle 2 which is initially optimized for operation in the high-pressure environment 10 . Later, when the first fleet vehicle 2 is traveling in the low-pressure environment 10', a corresponding engine operating data set, for example that previously sent by the second fleet vehicle 2' to the fleet server 7 transmitted engine operating data set are transmitted.
- a corresponding generating unit 9 can be provided for this purpose. Since the fleet can include a large number of fleet vehicles 2, 2', which in turn are located in a large number of different environments 10, 10' and can generate a large number of engine operating data sets, methods for generating optimized meta-engine operating data sets can also be used of machine learning are used.
