Embodiment Construction

[0038] figure 1 Diagram 10 is used to determine the installation in the vehicle, in image 3 A first embodiment of the method of the actuation-induced behavior of a valve 12 for regulating the flow of a medium as a liquid is shown schematically in FIG.

[0039] Valve 12 is used for example in image 3 In the hydraulic system of the vehicle shown schematically in . The hydraulic system has at least one hydraulic circuit 18 through which a medium can flow, the medium being oil. The hydraulic system also includes at least one pump 16 arranged in a hydraulic circuit 18 for delivering oil. Oil is conveyed by means of a pump 16 from an oil sump 13 through a hydraulic circuit 18 and from there to a valve 12 . In this case, the pump 16 has at least one pump element 20 and an electric motor 22 with which the pump element 20 is driven or can be driven. By driving the pump element 20 , oil is conveyed through the hydraulic circuit with the pump element 20 .

[0040] In order to dri...

Abstract

The invention relates to a method for ascertaining control-caused behavior of a valve (12) installed in a vehicle for adjusting a flow of a medium, comprising the following steps: operating a pump (16), which has an electric motor (22) and at least one pump element (20) for conveying the medium, such that the medium is conveyed by means of the pump (16) in that the pump element (20) is driven by means of the electric motor (22); controlling the valve (12) by means of an electronic computing device (28) of the vehicle, wherein the control of the valve (12) is varied by means of the electronic computing device (28); while the medium is conveyed by means of the pump (16) and while the control of the valve (12) is varied: sensing at least one parameter that characterizes the operation of the pump (16); and ascertaining the behavior of the valve (12) in accordance with the sensed parameter.

Description

technical field [0001] The invention relates to a method for determining a characteristic / state of a valve installed in a vehicle, and a vehicle. Background technique [0002] The prior art, in particular from the construction of mass-produced vehicles, discloses the use of valves in vehicles, for example automobiles, with which the flow of a medium, for example a fluid, can be regulated. Usually the valve is arranged in the corresponding line and has at least one valve element which can be adjusted or moved between at least one first position and at least one second position. In the first position, at least a partial region of the flow cross-section of the line through which the medium can flow is blocked fluidically by the valve element. In at least one second position, the valve element releases the subregion so that the medium can flow through the subregion. [0003] The valve includes, for example, an electrically drivable actuator with which the valve element can be ...
