Description
Technical Field
The invention relates to a method for adjusting a measuring device in a motor vehicle (abgleich) according to the invention.
Background
A method and a device for battery state detection are known from EP 1271170B 1. The conclusion about the battery state is obtained by means of a first battery state detection system, wherein the conclusion about the battery state is obtained by means of a second battery state detection system in the event of faulty operation or failure of the first battery state detection system, wherein the first battery state detection system draws the conclusion about the battery state using a current measuring device and additionally using a temperature measuring device.
Since the steering capability of a vehicle is not impaired, but rather only becomes difficult to activate, a failure of the onboard power system is generally accepted in mass-produced vehicles today, since the driver can provide a fallback level (R ü ckfallbene), in order to increase the availability, a two-channel onboard power system has already been proposed, for example in WO 2015/135729 a 1.
Disclosure of Invention
The invention is based on the following tasks: the overall system is further simplified in the case of high demands. This object is achieved by the features according to the invention.
In contrast, the method according to the features of the invention has the following advantages: the overall system is further simplified in the case of high demands. According to the invention, this is achieved by: the energy store is influenced by a measuring device of the load distribution device as a function of the measured variable of the sensor. Particularly preferably, the measuring device is calibrated as a function of the measured variable of the sensor. In general, sensors with high measurement accuracy, which can then also be used for calibration purposes for load distribution devices, are used, in particular in the case of safety-relevant on-board electrical energy systems, for example for autonomous driving. Higher-quality measuring device with possible redundancy eliminationAnd (4) placing. This reduces the structural complexity and makes it possible to use more advantageous components for the measuring device. Furthermore, the often usual time-and cost-intensive calibration of the load distribution device or the measuring device thereof can be limited or even eliminated, for example at the end of the production. Furthermore, the state of the connection line (aging, faults, contact resistance) can be determined by means of additional diagnostic possibilities
Etc.).
In an expedient further development, the measured variable detected by the sensor is transmitted to the load distribution device. In the case of load distribution devices, certain evaluation devices are always present, which provide protection for the connected consumers, for example, against excessive loads caused by the respective evaluation device. In the case of a load distribution device, the comparison of the measured variable of the particularly preferred sensor with the measured variable of the measuring device can therefore already be carried out as follows: whether or in what form a calibration of the measuring device of the load distribution apparatus has to be carried out. An additional analysis processing device can be dispensed with. In particular, the calibration is preferably carried out in the presence of significant deviations between the measured variable of the sensor and the measured variable of the measuring device. Thus, unnecessary calibration runs can be avoided.
In an expedient further development, at least one switching device is controlled as a function of a measured variable of the measuring device, in particular in order to protect the load. The corresponding calibration function can be integrated particularly expediently into an electronic distribution device with an included protection function. Thereby simplifying the structure.
In an expedient further development, a characteristic variable, in particular the contact resistance, a fault situation such as a fault or an aging, of a line of the partial onboard power supply system, in particular between the energy store and the load distribution device, is determined as a function of the measured variable of the sensor and/or of the measured variable of the measuring device. The data connection between the sensors and the load distribution device, which is always present, can be used particularly simply for extending the functional analysis of the onboard power supply system.
In an expedient further development, the load distributor supplies power to safety-relevant consumers, in particular to consumers with redundant functions, in particular to consumers required for autonomous driving, such as steering, braking, trajectory planning, etc. The availability and accuracy of the device can thus be further improved with only a small amount of additional effort, even in the case of safety-relevant power supply systems.
Further embodiments that are suitable for this purpose result from further embodiments of the invention and from the description.
Drawings
The figure shows a block diagram for adjusting a measuring device.
Detailed Description
The invention is schematically illustrated according to embodiments in the drawings and will be further described below.
In this exemplary embodiment, a battery or accumulator is described as a possible energy store. Alternatively, however, other energy stores suitable for the task may also be used, for example energy stores based on inductance or capacitance, fuel cells, capacitors, etc.
The sensor 34, in particular a battery sensor, detects the voltage Ubatt at the energy store 32 and/or the current Ibatt of the energy store 32. The measured variables (Ubatt, Ibatt) are forwarded to the load distribution device 52 via the data connection 27. The sensor 34, in particular a battery sensor, is characterized by a very high measuring accuracy and a large functional range. The sensor 34 can now also be used to protect a vehicle electrical system, which is particularly safety-relevant, of which a part of the vehicle electrical system 28 is shown by way of example in this exemplary embodiment. Thus, the overhead, which is structurally and cost-intensive, can be reduced.
The load distribution device 52 or the current distributor serves to control and/or protect the various consumers 36. The load distribution device 52 is powered by the energy storage 32. Load distribution device 52 detects typical load variables of consumer 36 that are also available, for example, corresponding load current Ilv or voltage Ulv. The respective typical load variables of the consumers connected to load distribution device 52 are always available in load distribution device 52 by means of respective measuring devices, since load distribution device 52 generally ensures reliable protection of consumers 36 as a function of the load state in order to protect them, for example, from overcurrent. For this purpose, a corresponding switching device 33, in particular an electronic semiconductor switch, which is opened in the event of an overload, is provided in the load distribution device 52. For this purpose, corresponding switching devices, in particular electronic semiconductor switches, which open in the event of an overload, are provided in the load distribution device 52. Furthermore, the load distribution device 52 is provided with an analysis processing device 29. The measurement variables Ubatt, Ibatt of the sensor 34 and the measurement variables of the measuring device 30 are supplied to the evaluation device 29. The evaluation device 29 comprises, for example, a comparator which compares the measured variable Ibatt of the sensor 34 and the measured variable Ilv of the measuring device 30 with one another. On the basis of this comparison, the evaluation device 29 can, for example, act on the measuring device 30 in the context of a calibration. The measured values of the sensors 34 can thus be used, for example, as reference values for the measured values of the measuring device 30. If necessary, temperature compensation is performed, for example, using the temperature determined in the load distribution device 52. Such calibration may also be performed continuously.
In the case of redundant power supply to safety-relevant, functionally redundantly designed consumers 36, at least two such partial onboard electrical systems 28 can be provided in the vehicle, for example. In this case, a further energy store 32 can be provided in the further partial power grid, which further energy store has a further sensor 34 for detecting a characteristic variable of the further energy store 32.
The energy store 32 feeds only the part of the on-board electrical system 28 which is relevant for safety. The measured values of the sensors 34, the current measured values Ibatt, the voltage measured values Ubatt are communicated to the load distribution device 52 via a corresponding data connection 27 or communication path (e.g. a common bus system such as CAN, LIN, ethernet, etc.) of the load distribution device 52. Furthermore, the sensor 34 can detect a further characteristic variable, for example a temperature, at the energy store 32.
The measurement of the sensor 34 is compared with the measurement of the measuring device 30 of the load distribution device 52. The load distribution device 52 is provided with a corresponding evaluation device 29 or a comparison device. Since the sensors 34 generally provide more accurate measured values Ubatt and Ibatt, the internal measuring device 30 of the load distribution device 52, for example an internal current measuring device, is calibrated at any time during operation with the measured values of the sensors 34. The tolerances and temperature dependence of the measuring section can be compensated. In addition, the internal voltage measurement provided by the measuring device 30 can be compared with the voltage measurement of the sensor 34 to diagnose the connection line and the contact resistance Rb1 of this connection line.
Therefore, more advantageous components can be used for the measuring device 30. Furthermore, time-intensive and cost-intensive calibration of the load distribution device 52 or its measuring device 30 can be limited or even eliminated at the end of the production. Furthermore, the state (aging, faults, contact resistances, etc.) can be determined with additional diagnostic possibilities of the connection.
The described method is particularly suitable for increasing the reliability of an overall system, in particular for autonomous driving, for which particularly stringent safety requirements are usually imposed. However, the application of the present invention is not limited thereto.
