Definitions
- the invention is based on a method for supplying energy to at least one electrical vehicle assembly according to the preamble of independent claim 1.
- the present invention also relates to a corresponding voltage converter arrangement for supplying energy to at least one electrical vehicle assembly, with an evaluation and control unit which is implemented to carry out one for supplying energy to at least one electrical vehicle assembly.
- a scarf device part which converts an externally provided supply voltage to other voltage potentials required within the assembly.
- Such a circuit part is also referred to as a voltage converter and delivers within the specified input voltage one or more defined output voltages for supplying the subsequent assemblies.
- a minimum input voltage value is required, from which the voltage converter is able to deliver the required output voltage. In current practice, this minimum input voltage value is only tied to a certain first voltage value; if this is exceeded, the voltage converter starts with the voltage conversion, if a certain, matching second voltage value is not reached, then the voltage conversion is deactivated again.
- a device with a plurality of sensors for a vehicle and a generic method for the energy supply of at least one vehicle assembly are known.
- the device comprises an interface with which the device communicates with control units of the vehicle.
- the device furthermore has a generic voltage converter arrangement which can be connected to the energy network of the vehicle and to the at least one control device for supplying energy to the at least one control device and includes means for voltage conversion.
- the means for voltage conversion convert an input voltage from the energy network into at least one output voltage for supplying energy to the at least one control device.
- the procedure checks whether the input voltage from the energy network is available. If this is the case, the input voltage continues to be converted into the at least one output voltage. If this is not the case, however, then an energy reserve is used in order to supply the plurality of sensors and the at least one control device with energy for a certain period of self-sufficiency.
- the method for supplying energy to at least one electrical vehicle assembly with the features of independent claim 1 and the voltage converter arrangement for supplying energy to at least one electrical vehicle assembly each have the advantage that the load capacity of a supply source that provides the input voltage for voltage conversion is checked before the voltage conversion of the input voltage into at least one output voltage is carried out.
- the invention is based on the fact that an internal resistance of the supply source is assessed before the at least one voltage converter is activated and only when this falls below a certain value, the at least one voltage converter is activated.
- This method can be used to ensure that the input voltage does not collapse as a result of the load when the at least one voltage converter is activated and thus deactivates the voltage converter. This means that when the voltage converters are activated, there is enough input power to ensure that the voltage converters can continue to work. This means that sporadic switching on and off, which is critical for subsequent stages, can no longer occur.
- Embodiments of the present invention provide a method for supplying energy to at least one electrical vehicle assembly, in which an input voltage provided by at least one supply source is monitored and converted into at least one output voltage which is applied to the at least one vehicle assembly.
- the supply source is loaded with a specifiable current level when the applied input voltage exceeds a predeterminable setpoint voltage, the input voltage being converted or converted into the at least one output voltage if the input voltage remains above the specifiable setpoint voltage despite the load on the supply source.
- a voltage converter arrangement for supplying energy to at least one electrical vehicle assembly with at least one voltage converter, which is designed to convert or convert an input voltage, which is provided by at least one supply source, into at least one predeterminable output voltage, which is to be used the at least one vehicle assembly is applied, a voltage monitor, which is designed to detect the input voltage, and an evaluation and control unit proposed, which is designed to carry out the method for energy supply of at least one electrical vehicle assembly.
- the predetermined current level enables a simple and quick check as to whether the internal resistance of the supply source has a sufficiently small value so that the supply source can provide the power required to operate the at least one voltage converter.
- the current level for checking the load can advantageously be adapted to the specifications of the supply sources and voltage converters used.
- the evaluation and control unit can be understood to mean an electrical assembly which processes or evaluates sensed sensor signals.
- the evaluation and control unit can have at least one processing unit for processing signals or data, at least one storage unit for storing signals or data, at least one interface to a sensor or another assembly for reading in sensor signals or for outputting control signals and / or have at least one communication interface for reading in or outputting data that is embedded in a communication protocol.
- the at least one interface can be designed in terms of hardware and / or software. In the case of hardware development, the interfaces can, for example, be part of a so-called system ASIC (ASIC: application-specific integrated circuit), which contains a wide variety of functions of the evaluation and control unit.
- ASIC application-specific integrated circuit
- the evaluation and control unit itself can be designed as a system ASIC (ASIC: application-specific integrated circuit).
- ASIC application-specific integrated circuit
- the interfaces are separate, integrated circuits or at least partially consist of discrete components.
- the interfaces can be software modules that are present, for example, on a microcontroller alongside other software modules.
- the computing unit can be, for example, a signal processor, a microcontroller or the like, wherein the storage unit can be a flash memory, an EEPROM or a magnetic storage unit.
- the communication interface can be designed to read in or output data wirelessly and / or wired.
- a computer program product with program code that is stored on a machine-readable carrier such as a semicon- ductor, a hard disk or an optical memory and is used to carry out the evaluation when the program is executed by the evaluation and control unit.
- the load on the supply source can be switched off before the input voltage is converted into the at least one output voltage. This can prevent the supply source from being subjected to additional loads during voltage conversion.
- the input voltage cannot be converted into the at least one output voltage if the input voltage drops below the preset nominal voltage value due to the load on the supply source. This enables reliable voltage conversion or voltage conversion to be achieved, since sporadic switching on and off is prevented.
- the supply source can be loaded with the specifiable current level, for example, for a specifiable period of time. If the input voltage does not drop during this period, the supply source is sufficiently stable.
- the period of time can advantageously be adapted to the specifications of the supply sources and voltage converters used.
- the load on the supply source can be switched off when the input voltage falls below the predeterminable setpoint voltage value. In this way, further damage to the supply source can be prevented or at least reduced.
- the evaluation and control unit can be designed to activate the at least one voltage converter as a function of specifiable criteria.
- the voltage monitor can also be designed to continuously compare the detected input voltage with a specifiable setpoint voltage value and to output the comparison result to the evaluation and control unit. The ver at the same time as a predetermined setpoint voltage value enables monitoring of the input voltage that can be implemented very easily.
- the evaluation and control unit can also be designed to activate a switchable current sink, which loads the at least one supply source with a specifiable current level when the input voltage is above the specifiable threshold value. The use of a switchable current sink enables the load capacity of the supply source to be checked quickly and easily.
- the evaluation and control unit can activate the at least one voltage converter if the detected input voltage remains above the predeterminable threshold value after activating the current sink, or not activate it if the input voltage falls below the predeterminable nominal voltage value due to the load on the supply source. This enables reliable voltage conversion or voltage conversion to be achieved, since sporadic switching on and off can be reliably prevented.
- the setpoint voltage value of the voltage monitor can be specified as a fixed or freely selectable threshold value.
- a freely selectable threshold value enables better adaptation to the specifications of the supply sources and voltage converters used, while a fixed, predetermined threshold value can be implemented more easily and cost-effectively.
- the current level of the switchable current sink can be specified as a fixed or freely selectable current value.
- a freely selectable current level enables better adaptation to the specifications of the supply sources and voltage converters used, while a fixed current level can be implemented more easily and cost-effectively.
- the evaluation and control unit and the voltage monitor and the switchable current sink can be combined to form a monitoring device.
- the monitoring device can preferably be designed as an application-specific integrated circuit (ASIC).

If this is not the case, then the method 100 continues with a step S160, in which the load on the supply source 5 is deactivated. The method is then continued with step S100. This means that the input voltage UE is not converted into the at least one output voltage UA is when the input voltage UE drops below the predeterminable setpoint voltage value due to the load on the supply source 5. If the input voltage UE remains above the setpoint voltage value despite the load on the supply source 5, then in a step S150 the input voltage UE is converted into at least one output voltage UA, which is applied to the at least one vehicle assembly.
