Description

[0001] The present invention relates to a method for controlling a value of a physical quantity in a technical system of a vehicle, a vehicle, a computer program product, a computer-readable medium and a data carrier signal.

[0002] An electric vehicle (as a technical system) can have an electrical system with a high-voltage side and a low-voltage side, wherein the high voltage on the high-voltage side, e.g., 400 V(ols), is converted to a lower voltage, e.g., 12 V(ols), for the low-voltage side by means of a DC-DC converter. The low-voltage side of the electric vehicle may contain high-power electrical consumers with high peak loads, such as electric power steering and / or electric brakes and / or a data processing system for assisted, in particular automated, and preferably autonomous, driving. Such consumers can cause high currents with high current gradients on the low-voltage side. Adversely, these high currents can, for example, cause a voltage drop on the low-voltage side and thus impair the functionality of electrical components on the low-voltage side.

[0003] Furthermore, the electric vehicle can, as a (further) technical system, have a hydraulic system with a low-pressure side and a high-pressure side, whereby the low pressure on the low-pressure side can be converted to a higher pressure for the high-pressure side by means of a pump. In this context, a hydraulic consumer on the high-pressure side can cause a pressure drop on the high-pressure side and thus impair the functionality of hydraulic units on the high-pressure side.

[0004] It is known, for example, for electrical systems to (disadvantageously) oversize the power of a DC-DC converter and / or to oversize electrical units on the low-voltage side, so that the functionality of electrical units on the low-voltage side is ensured or substantially ensured.

[0005] From DE 10 2019 114 590 A1 and DE 20 2022 001 025 U1, a method for checking a value of a physical quantity in at least one technical system of a vehicle is known.

[0006] It is an object of the present invention to at least partially overcome the disadvantages described above. In particular, it is an object of the present invention to provide a method and / or a vehicle by which the functionality of technical units on the output side of a technical system of the vehicle, e.g., electrical consumers on the low-voltage side of an electrical system, is particularly advantageously ensured, and / or the dimensioning of technical units on the output side of the technical system is particularly advantageous, and / or the technical system is designed to be particularly simple.

[0007] The foregoing problem is solved by a method having the features of claim 1, a vehicle having the features of claim 10, a computer program product having the features of claim 11, a computer-readable medium having the features of claim 12, and a data carrier signal having the features of claim 13. Further features and details of the invention will become apparent from the dependent claims, the description, and the drawings. Features and details described in connection with the method according to the invention naturally also apply in connection with the vehicle and / or computer program product and / or computer-readable medium and / or data carrier signal according to the invention, and vice versa, so that the disclosure of the individual aspects of the invention always makes, or can make, reciprocal reference.

[0008] According to a first aspect, the present invention discloses a method for controlling the value of a physical quantity in at least one technical system of a vehicle. The at least one technical system has an input side and an output side. Furthermore, the technical system comprises a converter component with at least one input and at least one output, wherein the input of the converter component is connected to the input side and the output of the converter component is connected to the output side of the technical system, and wherein the converter component is configured to convert the value of the physical quantity between an input region on the input side of the technical system and an output region on the output side of the technical system. Furthermore, the converter component can be controlled, in particular by means of a control signal, such that at least the value of the physical quantity at the output of the converter component can be controlled.Furthermore, the procedure includes as a step the detection of a possible occurrence of at least one event with an effect at least on the output side of the technical system, wherein in particular the detection of the possible occurrence of the at least one event with an effect at least on the output side of the technical system is carried out by means of a detection unit of the vehicle, i.e., is performed.Furthermore, the method includes, as a step, controlling the converter component by means of a control signal, in particular by means of a control signal from a vehicle recognition unit, based on the detected possible occurrence of at least one event, in order to control the physical quantity at the output of the converter component at least temporarily from a first value to a second value different from the first value, so that the effect on the output side of the technical system due to the possible occurrence of at least one event is counteracted.

[0009] The process steps described above and below can be carried out individually, together, simply, multiple times, in parallel and / or sequentially in any order, provided it is technically feasible.

[0010] The input side can have multiple technical units as well as technical connections for linking these units. In particular, the input side, with its technical connections and multiple technical units, can be configured as a network. For example, in an electrical system, a high-voltage side can be the input side. The high-voltage side can, for example, be a battery system for providing electrical energy at, say, 400 volts. Technical connections in an electrical system can be understood as electrical conductors. Technical connections in a hydraulic and / or pneumatic system can be understood as fluid-carrying lines.

[0011] Furthermore, the output side can have multiple technical units as well as technical connections for linking these units. In particular, the output side, with its technical connections and multiple technical units, can be configured as a network. For example, in an electrical system, a low-voltage side can be the output side. The low-voltage side can, for example, comprise an electrical load and / or an electrical generator as a single technical unit.

[0012] In an electrical system (as a technical system), the converter component can be a voltage converter, in particular a DC / DC converter. The DC / DC converter can also be understood as a DC-DC converter. In a hydraulic and / or pneumatic system (as a technical system), the converter component can be, for example, a pump.

[0013] In particular, the technical system can have only a single converter component, e.g., a single DC-DC converter, for converting the physical quantity between an input region on the input side of the technical system and an output region on the output side of the technical system. Thus, the technical system can be designed to be particularly simple. For example, an electrical system, as a technical system, can have only a single DC-DC converter for converting a voltage (as the physical quantity) between the input region on the input side (high-voltage side) of the electrical system and the output region on the output side (low-voltage side) of the electrical system. For example,Furthermore, a hydraulic and / or pneumatic system as a technical system may only have a single pump for converting a pressure (as the physical quantity) between the inlet area on the input side (low pressure side) of the hydraulic and / or pneumatic system and the outlet area on the output side (high pressure side) of the hydraulic and / or pneumatic system.

[0014] The high-voltage side of the vehicle's electrical system has a voltage of more than 60 V(olt), e.g. at least 400 V, and / or the low-voltage side of the vehicle's electrical system has a voltage of less than 60 V(olt), e.g. (approx.) 6 V or (approx.) 12 V or (approx.) 24 V.

[0015] The terms "input range" and "output range" in the expression "where the converter component is designed to convert the value of the physical quantity between an input range on the input side of the technical system and an output range on the output side of the technical system" are intended to express that the converter component is designed to convert the physical quantity within a certain (value) range of the physical quantity on the input side to a certain (value) range of the physical quantity on the output side and / or vice versa.

[0016] The phrase "whereby the converter component can be controlled in such a way that at least the value of the physical quantity at the output of the converter component can be controlled" is intended to express that the converter component can be controlled, for example, by means of a control signal, in order to control the value of the physical quantity at the output of the converter component, particularly within a specific or defined range. For example, in an electrical system, a DC-DC converter can be controlled, particularly by means of a control signal, in order to control the value of the electrical voltage (as the physical quantity) at the output of the DC-DC converter, particularly within a specific or defined range. Controlling the value of the physical quantity at the output of the converter component can be described as regulating the physical quantity, for example.an electrical voltage at the output of the converter component, wherein for the control the physical quantity, e.g. the electrical voltage, at the output of the converter component is preferably detected.

[0017] An event with an effect on at least the output side of a technical system is understood to be, in particular, an event that has an effect on the physical quantity at the output side of the technical system. The effect on the physical quantity at the output side of the technical system can be a change in the magnitude of the physical quantity, especially an increase or a decrease in its value. For example, in an electrical system, a surge in electrical load caused by the sudden application of an electric brake can cause a voltage drop at the output side of the electrical system. Furthermore, in a hydraulic system, a surge in hydraulic load caused by the sudden application of a hydraulic brake can cause a pressure drop at the output side of the hydraulic system.

[0018] Detecting the potential occurrence of at least one event with an effect on at least the output side of the technical system can also be understood as predicting the potential occurrence of at least one event with an effect on at least the output side of the technical system. In other words, the potential occurrence of at least one event with an effect on at least the output side of the technical system should be detected or predicted so that the effect on the output side of the technical system can be counteracted proactively by controlling the converter component before, for example, a load peak occurs, to monitor the physical quantity to the second value.

[0019] Furthermore, the detection of the possible occurrence of at least one event with an effect at least on the output side of the technical system can be carried out by means of a detection unit in the vehicle, wherein, in particular, upon a detected possible occurrence of at least one event (with an effect at least on the output side of the technical system), the detection unit controls the converter component by means of the control signal in order to monitor the physical quantity at the output of the converter component, at least temporarily, at least from the first value to the second value, in particular to monitor preventively. For example,The detection unit can recognize or predict the possible occurrence of at least one event affecting at least the output side of the technical system based on at least one signal, in particular a control signal, from an artificial intelligence of the vehicle for controlling a unit of the vehicle's technical system, and / or based on the measured computing power of a data processing system of the vehicle, and / or based on a measured electrical quantity of a data processing system of the vehicle. This detection or prediction can be achieved by comparing the at least one signal from the artificial intelligence with a reference signal, and / or by comparing the measured computing power of the data processing system with reference data, and / or by comparing the measured electrical quantity, e.g., an electric current, of a data processing system of the vehicle with reference data.It is additionally or alternatively conceivable that at least one signal from the artificial intelligence is evaluated using a method for determining the probability of an event occurring, and / or that the recorded computing power of the data processing system is evaluated using a method for determining the probability of an event occurring, and / or that the recorded electrical quantity of the data processing system is evaluated using a method for determining the probability of an event occurring, in order to recognize (by means of the evaluation or evaluations) the possible occurrence of at least one event with an effect at least on the output side of the technical system.

[0020] By controlling the converter component with the control signal (due to the detected potential occurrence of at least one event, e.g., possible braking and / or braking requested by an artificial intelligence), the physical quantity at the converter component's output is at least temporarily controlled from the first value to a second value that differs from the first. For example, in an electrical system (as a technical system), the electrical voltage of a DC-DC converter at an output of a DC-DC converter can be controlled, at least temporarily, from a first voltage value to a second voltage value that differs from the first.During braking with an electric brake (as an electrical load on the low-voltage side), the voltage at the output of the DC-DC converter is increased, particularly (preemptively or preventively), to counteract, for example, a (potential) voltage drop on the low-voltage side of the electrical system. Conversely, when electrical energy is fed into the low-voltage side by an electrical generator, the voltage is decreased, particularly (preemptively or preventively), to counteract, for example, a (potential) overvoltage on the low-voltage side of the electrical system.Thus, by monitoring the electrical quantity at the output of the DC-DC converter, the effect on the low-voltage side of the electrical system due to the possible occurrence of at least one event can be counteracted preventively or proactively, preferably before the event occurs, at least temporarily, by switching from a first value to a second value that differs from the first. This allows the functionality of technical units on the output side of a vehicle's technical system, e.g., electrical consumers on the low-voltage side of an electrical system, to be particularly advantageously ensured, and / or allows the dimensions of technical units on the output side of the technical system to be kept particularly small, and / or allows the technical system to be designed particularly simply.

[0021] It can be advantageous if, in a method according to the invention, the control of the converter component by the control signal is carried out, based on the detected possible occurrence of at least one event, in such a way that the physical quantity at the output of the converter component is checked from the first value to the second value before and / or at the same time as the occurrence of the at least one detected event, and in particular, is already controlled. Thus, the effect of the event on the output side, in particular on the physical quantity at the output side, can be kept to a minimum when the event occurs.

[0022] It can be advantageous if, in a method according to the invention, after checking the physical quantity at the output of the converter component for the second value, the physical quantity at the output of the converter component is at least temporarily checked for a third value. In other words, it is conceivable that the converter component is controlled by the control signal, based on the detected possible occurrence of at least one event, in such a way that the physical quantity at the output of the converter component (starting from the first value) is first checked for the second value and then for the third value. Thus, a dynamic effect of the at least one event on the output side, in particular on the physical quantity at the output side, of the technical system can be counteracted particularly advantageously (preemptively). For example,In an electrical system, different electrical load peaks can occur successively on the low-voltage side during a parking operation. Therefore, monitoring the voltage at the output of the DC-DC converter for a second and a third value can be particularly advantageous for the low-voltage side of the electrical system. The third value is specifically different from the first and second values ​​of this physical quantity.

[0023] In a method according to the invention, it is provided that, prior to the activation of the converter component for monitoring the physical quantity at the converter component's output, a check is performed, at least temporarily, to determine whether monitoring the physical quantity at the converter component's output for monitoring the second value is possible, and in particular, whether it is permitted. This check is carried out, in particular, by means of a monitoring unit of the vehicle. Thus, it can be ensured, for example, that the functionality of technical units on the output side of the vehicle's technical system remains guaranteed, particularly easily. For example, the physical quantity at the converter component's output can be measured and compared with a reference value. For example, in an electrical system, a current, i.e.,The current electrical voltage at the output side of the DC-DC converter is measured and compared with a reference value to check whether it is possible, and in particular permitted, to control the electrical voltage at the output of the DC-DC converter to the second value.

[0024] It can be advantageous if, in a method according to the invention, the vehicle has an artificial intelligence for assisted, in particular automated, preferably autonomous, driving, wherein the detection of the possible occurrence of at least one event with an effect at least on the output side of the technical system is based on at least one signal, in particular a control signal, of the artificial intelligence, particularly for controlling a unit of the vehicle's technical system. Thus, event-based events (during driving) of the vehicle with an effect at least on (or in) the output side of the technical system can be detected particularly advantageously. For example, the artificial intelligence for assisted, in particular automated, preferably autonomous, driving can specify requirements regarding longitudinal and / or lateral acceleration of the vehicle. For example,These signals can be fed to a vehicle detection unit to recognize the potential occurrence of at least one event that affects at least the output side of the technical system. Longitudinal and / or lateral acceleration can trigger requirements, for example, for a change in the steering angle of the vehicle. Based on a known proportionality, the electrical power consumption of the steering system can be predicted, and the converter component can be controlled accordingly by the control signal, particularly before and / or at the time of the occurrence of the at least one detected event, in order to counteract the effect on the output side of the technical system resulting from the vehicle steering.It can be advantageous if, in a method according to the invention, at least the level of the second value, to which the physical quantity at the output of the converter component is at least temporarily controlled based on the first value, depends on a value of at least one signal, in particular a control signal, of the artificial intelligence. For example, if a (potential) "strong" steering maneuver of the vehicle is detected or predicted, the electrical voltage at the output of the DC-DC converter (based on the first value) is increased more than if a (potential) "weak" steering maneuver of the vehicle is detected or predicted. The detection of a "strong" or "weak" steering maneuver can be achieved, for example, by comparison with reference data, in particular by a vehicle recognition unit.

[0025] It can be advantageous if, in a method according to the invention, the detection of the possible occurrence of at least one event with effects at least on the output side of the technical system is based on a detected computing power of a data processing system of the vehicle and / or on a detected electrical quantity of a data processing system of the vehicle, i.e., is carried out, wherein in particular a detection unit of the vehicle is configured to detect the possible occurrence of at least one event with effects at least on the output side of the technical system based on the detected computing power of the data processing system of the vehicle and / or on the detected electrical quantity of the data processing system of the vehicle.Thus, the potential occurrence of at least one event with an impact on at least the output side of the technical system can be detected or predicted particularly advantageously and easily. The vehicle's data processing system is, in particular, a data processing system for assisted, especially automated, preferably autonomous, driving of the vehicle, wherein, in particular, the artificial intelligence for assisted, especially automated, preferably autonomous, driving runs at least partially on the data processing system. An electrical parameter of the data processing system can be understood, in particular, as an electrical current of the data processing system. For example,Can the electrical current of the data processing system be monitored to enable the detection of the potential occurrence of at least one event with an impact on the output side of the technical system, based on the electrical current of the data processing system? The complexity of the vehicle's environment can directly influence the energy consumption of the data processing system and / or its computing power and / or its idle processes and / or the system runtime of the artificial intelligence.It can therefore be advantageous if, in a method according to the invention, at least the value of the second parameter, to which the physical quantity at the output of the converter component is at least temporarily monitored relative to the first parameter, depends on idle processes of the vehicle's data processing system, in particular the data processing system for assisted, especially automated, preferably autonomous, driving of the vehicle, and / or on a system runtime of an artificial intelligence of the vehicle for assisted, especially automated, preferably autonomous, driving. Thus, the value of the second parameter, to which the physical quantity at the output of the converter component is at least temporarily monitored relative to the first parameter, can be determined in a particularly simple manner.

[0026] It can be advantageous if, in a method according to the invention, the technical system is an electrical system with a high-voltage input and a low-voltage output, wherein the converter component is a DC-DC converter. It is also conceivable that the technical system is a hydraulic and / or pneumatic system with a high-pressure input and a low-pressure output, wherein the converter component is a pump.

[0027] It can be advantageous if, in a method according to the invention, the vehicle (in addition to the at least one technical system) has a second technical system, wherein a converter component of the second technical system is controlled by a (further) control signal due to the detected possible occurrence of the at least one event, in order to control a physical quantity, in particular a physical quantity different from the physical quantity of the first system, of the second technical system at an output of the converter component of the second technical system at least temporarily from a first value to a second value different from the first value, so that the effect on the output side of the second technical system due to the possible occurrence of the at least one event is counteracted.Thus, if a potential event is detected that affects both the output of the first and the second technical systems, countermeasures can be taken. In particular, the (additional) control signal for activating the converter component can be output by a detection unit in the vehicle. For example, at least one technical system can be an electrical system of the vehicle, and the second technical system can be a hydraulic and / or pneumatic system, where the electrical system has a DC-DC converter as its converter component and the hydraulic and / or pneumatic system has a pump as its converter component. Upon detection of a potential event, the DC-DC converter and the pump can be activated by a respective control signal to generate a voltage at the output of the DC-DC converter and the pump, respectively.to change the pressure at the pump output in such a way as to counteract any effect on the output side of the electrical system or the hydraulic and / or pneumatic system.

[0028] Features and / or details and / or advantages described in the preceding and / or following paragraphs relating to the at least one technical system or to the components of the at least one technical system can also be transferred to the second technical system, and vice versa.

[0029] According to a second aspect, the present invention relates to a vehicle wherein the vehicle is configured to carry out a method according to one of the preceding claims.

[0030] The vehicle, e.g., a passenger car, a truck, or a motorcycle, is in particular an assisted, especially automated, preferably autonomous, vehicle, wherein the vehicle in particular features artificial intelligence for assisted, especially automated, preferably autonomous, driving. Artificial intelligence is understood to mean in particular a computer program, wherein the computer program is based, for example, on machine learning or neural networks. For assisted, especially automated, preferably autonomous, driving, the vehicle may in particular feature a data processing system, wherein the data processing system preferably includes a computing unit and / or a storage unit. The data processing system and / or the artificial intelligence is / are in particular arranged on the output side of the technical system.Furthermore, the artificial intelligence can be trained to control, preferably to steer, a technical unit in the output side of the vehicle's technical system by means of a signal, in particular by means of a control signal or steer signal.

[0031] Furthermore, the vehicle can have a detection unit for recognizing the possible occurrence of at least one event with an effect at least on the output side of the technical system, wherein the detection unit is preferably configured to control the converter component of the at least one technical system by means of a control signal. The detection unit can include a processing unit and / or a data storage device for recognizing the possible occurrence of the at least one event with an effect at least on the output side of the technical system.

[0032] Furthermore, the vehicle may have a verification unit to check whether it is possible, and in particular permitted, to check the physical quantity at the output of the converter component against the second value. In particular, the verification unit may be at least partially integrated with the detection unit.

[0033] The vehicle according to the second aspect of the invention thus has the same advantages as those already described for the method according to the first aspect of the invention.

[0034] According to a third aspect, the present invention discloses a computer program product comprising commands that cause a vehicle according to the invention to perform process steps according to a method according to the invention.

Furthermore, the computer program product can be implemented using software, one or more special electronic circuits (i.e., in hardware), or in any hybrid form (i.e., using both software and hardware components).

[0036] The computer program product according to the third aspect of the invention thus has the same advantages as those already described for the method according to the first aspect of the invention or the vehicle according to the second aspect of the invention.

[0037] According to a fourth aspect, the present invention discloses a computer-readable medium on which a computer program product according to the invention is stored. In particular, the computer program product can be stored on a computer-readable storage medium such as a data disk, a removable drive, volatile or non-volatile memory, or an integrated memory / processor.

[0038] The computer-readable medium according to the fourth aspect of the invention thus has the same advantages as those already described for the method according to the first aspect of the invention, the vehicle according to the second aspect of the invention, or the computer program product according to the third aspect of the invention.

[0039] According to a fifth aspect, the present invention discloses a data carrier signal that transmits a computer program product according to the invention. In particular, the computer program product can be made available or provided in a network such as the Internet, from which it can be downloaded by a user or executed online as needed.

[0040] The data carrier signal according to the fifth aspect of the invention thus has the same advantages as those already described for the method according to the first aspect of the invention, the vehicle according to the second aspect of the invention, the computer program product according to the third aspect of the invention, or the computer-readable medium according to the fourth aspect of the invention.

[0041] Further improvements to the invention will become apparent from the following description of some exemplary embodiments of the invention, which are schematically illustrated in the figures. All features and / or advantages arising from the claims, the description, or the drawings, including design details, spatial arrangements, and process steps, can be essential to the invention, both individually and in various combinations. It should be noted that the figures are for descriptive purposes only and are not intended to limit the invention in any way.

[0042] They show schematically: Fig. 1 a procedure, and Fig. 2 a vehicle.

[0043] In the following figures, identical reference numerals are used for the same technical features even for different embodiments.

[0044] Fig. Figure 1 schematically discloses a method for controlling a value of a physical quantity in at least one technical system 1 of a vehicle 100, as is the case, for example, in Fig. Figure 2 shows the at least one technical system 1 having an input side 10 and an output side 30. Furthermore, the technical system 1 comprises a converter component 20 with at least one input 21 and at least one output 22, wherein the input 21 of the converter component 20 is connected to the input side 10 and the output 22 of the converter component 20 is connected to the output side 30 of the technical system 1, and wherein the converter component 20 is configured to convert the value of the physical quantity between an input area on the input side 10 of the technical system 1 and an output area on the output side 30 of the technical system 1, and wherein the converter component 20 can be controlled such that at least the value of the physical quantity at the output 22 of the converter component 20 can be monitored. For example,The at least one technical system 1 is an electrical system with a high-voltage side as input side 10 and a low-voltage side as output side 30, wherein the converter component 20 is a DC-DC converter. It is also conceivable that the at least one technical system 1 is a hydraulic and / or pneumatic system with a high-pressure side as input side 10 and a low-pressure side as output side 30, wherein the converter component 20 is a pump. Furthermore, the method comprises, as a step, the detection 320 of a possible occurrence of at least one event with an effect at least on the output side 30 of the technical system 1.Furthermore, the method includes as a step controlling 340 of the converter component 20 by a control signal based on the detected possible occurrence of at least one event, in order to control the physical quantity at the output 22 of the converter component 20 at least temporarily from a first value to a second value different from the first value, so that the effect on the output side 30 of the technical system 1 due to the possible occurrence of at least one event is counteracted.

[0045] It can also be advantageous if, in a procedure according to Fig. 1 the control 340 of the converter component 20 by the control signal on the basis of the detected possible occurrence of at least one event is carried out in such a way that the physical quantity, e.g. a voltage or a pressure, at the output 22 of the converter component 20 is checked from the first value to the second value before and / or at the same time as the occurrence of the at least one detected event.

[0046] It can also be advantageous if, in a procedure according to Fig. 1. After checking the physical quantity at output 22 of the converter component 20 for the second value, the physical quantity at output 22 of the converter component 20 is checked at least temporarily for a third value. 360. Thus, an event that has several successive effects of varying intensity or magnitude, e.g., in the form of load peaks of varying intensity, on the output side 30 of the technical system 1 can be counteracted particularly advantageously, since the physical quantity at output 22 of the converter component is changed or adjusted in such a way as to counteract the respective effect particularly advantageously.

[0047] It can also be advantageous if, in a procedure according to Fig. 1. Before the converter component 20 is activated, the physical quantity at the output 22 of the converter component 20 is checked at least temporarily from the first value to the second value, 330, to verify whether checking the physical quantity at the output 22 of the converter component 20 to the second value is possible, in particular permitted.

[0048] It can also be advantageous if, in a procedure according to Fig. 1. The vehicle 100 has an artificial intelligence 110 for assisted, in particular automated, preferably autonomous, driving, wherein the detection 320 of the possible occurrence of the at least one event with an effect at least on the output side 30 of the technical system 1 is based on at least one signal, in particular a control signal, of the artificial intelligence 110 for controlling a unit of the technical system 1 of the vehicle 100 321.
