Embodiment Construction

[0042] figure 1 The hydraulic system 2 shown in is suitable and set up for operating and lubricating a motor vehicle transmission, in particular a shift transmission, of a motor vehicle (not shown). To this end, the hydraulic system 2 comprises a fluid or oil circuit 4 shown in dashed lines for conducting (hydraulic) fluid 6 , in particular (transmission) oil. The hydraulic system 2 has two fluid or oil pumps 8 and 10 for conveying the oil 6 in the oil circuit 4 . The oil pump 8 is designed here as a main pump, while the oil pump 10 is designed as an auxiliary or supplementary pump of the oil circuit 4 .

[0043] In this case, the oil pump 8 is coupled to the internal combustion engine of the motor vehicle and can be functionally driven by the internal combustion engine for conveying the oil 6 . The oil pump 10 is implemented electrically and has a driven electric motor 12 . The electric motor 12 is designed, for example, as a brushless DC motor and has a rotatably mounted ...

Abstract

The invention relates to a method for conveying a fluid (6) of a fluid circuit (4) with an electric fluid pump (10) of a motor vehicle, in particular an oil pump, wherein the fluid circuit (4) is pumped by means of the fluid pump (10) The fluid pressure (p) of the fluid (6) in is adjusted to the target pressure (p 目标 ), and wherein the actual pressure of the fluid (6) (p 实际 ).

Description

technical field [0001] The invention relates to the field of pumps, preferably electrically or electrically operated or driven (fluid) pumps, and to a circuit for conveying a fluid with an electric fluid pump in a motor vehicle, in particular in a motor vehicle transmission fluid approach. The invention also relates to a fluid pump operating according to this method and to a motor vehicle transmission having such a fluid pump. In this context, a fluid pump is to be understood in particular as an auxiliary or main pump, in particular an oil pump, in or for a motor vehicle. Background technique [0002] Electric fluid pumps and in particular also so-called auxiliary pumps or auxiliary pumps are used, for example, to deliver oil as (hydraulic) fluid for control tasks or to cool vehicles driven, for example, by an internal combustion engine, with hybrid technology or electric drive A particularly moving part or component of (a motor vehicle). Such an oil pump usually generate...
