Method for determining an average value of pressure oscillation in a low-pressure fuel system for a motor vehicle, computer-readable storage medium and low-pressure fuel system

摘要

According to the invention, the technology disclosed here relates to a method for determining a mean value (22) of pressure oscillations (20) in a low-pressure fuel system (12) for a motor vehicle (10), with the following steps: a detection device (24) of the low-pressure fuel system (12) over a predetermined time range; - specification of a mathematical model (28) for determining the mean value (22) of the pressure oscillations (20) as a controlled variable for the low-pressure fuel system (12), the mathematical model (28 ) is provided in an electronic computing device (26) of the low fuel pressure system (12); - Determination of at least one constant pressure value in the detected pressure oscillations (20) and a pressure value that changes linearly over time in the detected pressure oscillations (20) on the basis of the mathematical model (28 ) by means of the electronic computing device (26); and- determining the mean value (22) of the pressure oscillations (20) by adding the determined constant pressure value and the determined pressure value which changes linearly over time. The invention also relates to a computer-readable storage medium and a low-pressure fuel system (12).
