Definitions
- the invention relates to a method for operating a fluid delivery system, comprising a fluid delivery pump, a voltage manipulator and an electric motor, wherein the fluid delivery system is integrated into an electrical network and the electric motor is controllable by a voltage applied to the electric motor and the voltage manipulator is connected upstream of the electric motor.
- fuel delivery pumps are used to deliver the fuel from the fuel tank to the engine.
- electrically driven fuel delivery pumps are used which have a pump stage which can be driven by an electric motor.
- the fuel delivery pumps must ensure fuel delivery over a wide operating range. For example, the fuel delivery pumps must provide a sufficient flow both at full load of the engine and at low speeds or at standstill of the motor vehicle.
- the maximum capacity is the one hand, depends on the design of the fuel feed pump, whereby the maximum För ⁇ dermenge increases with increas ⁇ mender size of the fuel feed pump, and which is largely determined by the electric power on the other hand by the speed of the Pum ⁇ pennote.
- the maximum flow rate therefore also depends di ⁇ rectly from the supply voltage of the electric motor and the voltage applied to the electric motor current.
- the available electrical voltage in the on-board electrical system of a motor vehicle is regularly limited to a certain maximum, so that the voltage at the fuel delivery pump can not be increased arbitrarily and thus the maximum speed and thus the maximum flow rate is limited.
- the booster is formed, for example, by an electrical circuit of several components.
- a disadvantage of the known from the prior art devices is in particular that results from the use of the booster in operation, a disadvantageous power loss in elec ⁇ cal system, which causes in particular by the additional inductance of the booster and verwen ⁇ for the booster power semiconductors becomes. Furthermore, the boosters are not optimally controlled in order to optimally compensate for the resulting after ⁇ parts.
- An embodiment of the invention relates to a method for operating a fluid delivery system, with a Fluidför- derpumpe, with a voltage manipulator and with an electric motor, wherein the fluid delivery system in an electric Network is integrated and the electric motor is driven by a voltage applied to the electric motor voltage and the voltage manipulator is connected upstream of the electric motor, wherein the following steps are passed through:
- ⁇ determine the necessary speed of the fluid delivery pump for delivering the desired fluid flow rate
- a fluid delivery system may in particular be a fuel delivery system for delivering fuel from a fuel tank to an internal combustion engine.
- a fuel delivery system for delivering fuel from a fuel tank to an internal combustion engine.
- water or oil circuits are possible.
- a voltage manipulator is an electronic component, wel ⁇ ches may affect the voltage.
- the stress manipulator may be formed of a single component or by a plurality of combined elements.
- the control of the voltage manipulator ⁇ manipulator can, for example via a control ⁇ gene conditions.
- boosters can be used, which serve to amplify and / or the weakening of electrical signals. In this case, only the voltage level per se can be changed or, for example, the switching frequency of a signal.
- Thechrosmanipula ⁇ tor can be enabled in order to actively influence the voltage and thus for example to produce an increase or a Verrin ⁇ delay the voltage.
- the increase and / or reduction in the voltage can be achieved in addition to or Anstel ⁇ le by activation of voltage manipulator.
- the voltage manipulator can act as a filter for the switching frequencies in the electrical network.
- an electrical network is meant an interconnection of one or more components, for example, controllers, energy sources and actuators. This can be formed for example by the on-board voltage network of a motor vehicle.
- the electric motor of the fluid delivery system is connected to the electrical network such that its speed can be regulated.
- the speed of the electric motor and thus also the connected to the electric motor fluid delivery pump is an essential criterion to determine the fluid delivery rate of the fluid delivery pump.
- a ge ⁇ Wisse determinable speed level of the fluid feed pump is not ⁇ agile.
- the desired speed level can be achieved by applying a suitable voltage to the electric motor.
- the voltage manipulator can preferably be used to testify to a suitable voltage level at the electric motor ⁇ to it. This can ensure a sufficient fluid flow.
- the fuel delivery system can be controlled both by the applied voltage and by a speed specification who ⁇ . In this case, however, there is a relationship between the applied fuel supply and the speed which is established at the fuel delivery pump and is dependent on the respective fuel delivery system and the operating conditions. Preferably, a voltage is also determined in a controlled via the speed of the fuel delivery system, which must be applied to the ⁇ fuel pump to reach the predetermined speed.
- the electrical network is usually operated at a bestimm ⁇ th voltage level.
- the voltage with which the electric motor can be acted upon by the electrical network is therefore limited. This is also a possible ma ⁇ ximum speed is limited, because it depends directly on the voltage on the electric motor. Should be required to secure Stel ⁇ development of fluid flow a speed which makes a voltage higher than the maximum voltage in the electrical network necessary, this speed can not be achieved without changing the voltage.
- the voltage manipulator may appropriately boost the voltage of the electrical network to ultimately produce a voltage across the electric motor that is above the maximum voltage of the electrical network. The voltage manipulator can thus act as a voltage amplifier.
- the voltage manipulator may also be used to lower the voltage to a level that can not be provided by the electrical network. This is particularly advantageous in order not to have to unnecessarily reduce the voltage in the rest of the electrical network, since, for example, other consumers require a higher voltage level.
- the electric motor can be subjected to a very low voltage, resulting in a very low speed, while the voltage in the rest of the electrical network remains virtually unchanged.
- a reduction in the speed can alternatively be achieved, for example, by reducing the modulation frequency of a pulse width modulated signal used to drive the electric motor.
- acoustically adverse effects can be caused by a trailing reduction of the modulation frequency below a defined limit.

This is advantageous in order to expand the available speed range of the electric motor and thus of the fluid pump as a whole.
- the voltage manipulator acts here as a signal attenuator.
- This is particularly advantageous ⁇ way, when the electric network is operated with a very high voltage which is applied either permanently or temporarily limited to the electrical network. This is the case for example in an electric vehicle, which re ⁇ regularly has a significantly higher mains voltage. In particular ⁇ special during recuperation, so the recovery of electrical energy from the movement of the electric vehicle, a very high voltage level in the electrical network can be ent.
- the electrical network is operated with a predefinable mains voltage, wherein the voltage with which the electric motor is driven, by the voltage manipulator to a level above the mains voltage can be raised.
- theistsmanipula ⁇ gate acts as a signal amplifier, in particular raising the voltage level of the signal relative to the voltage level of the electrical ⁇ rule network, whereby a higher speed at the electric motor and thus also at the fluid pump can be generated.
- the range of use of a fluid delivery pump can thereby be increased towards the top, since the voltage gain allows operation at a higher speed.
- the speed range of the electric motor and thus the fluid delivery pump is thereby increased.
- the voltage can also be reduced below the voltage level of the rest of the electrical network. overall, the speed range will be able to reduce thus been extended ⁇ probably upwards as well as downwards.
- theorsmanipu ⁇ lator acts as a filter between the electric motor and the rest of the electrical network.
- a filter is particularly advantageous in order to keep differences, in particular in the switching frequency of the signals used, separated from each other before and after the voltage manipulator. For example, it is advantageous if the
- the remaining electrical network is much higher than the Heidelbergfreguenz between the voltage manipulator and the electric motor.
- the remaining electric network can be operated for example with a Wegfreguenz of about 500 kHz, thereby allowing a damping or filtering of the electrical network with simp ⁇ Cheren components and less effort than at significantly lower Heidelbergfreguenzen.
- the voltage manipulator can nevertheless be designed in such a way that the electric motor is driven at a substantially lower switching frequency, which may be, for example, 20 kHz to 25 kHz.
- the fluid delivery system is decoupled from the remaining electrical network with respect to the switching frequency of the drive signals by the voltage manipulator, wherein a lower switching frequency exists between the voltage manipulator and the electric motor than between the electrical network and the voltage manipulator.
- This is advantageous in order to allow easy Fil ⁇ esterification and / or damping of the electrical network, while the electric motor can still be supplied with a driving signal having a best possible Druckfreguenz.
- the voltage output by the voltage manipulator to the electric motor corresponds to the voltage in the rest of the electrical network, wherein the
- thepolsmanipu ⁇ lator serves as a damper between the Wegfreguenz of the drive signal of the electric motor and the Wegfreguenz in restli ⁇ chen electrical network.
