Method and device for determining the air consumption of an air spring

Abstract

The invention relates to a method for determining the air consumption (L) of an air spring (2) during operation, wherein the air spring (2) is connected to a compressed air supply (4) via a pipe (3) and the compressed air supply (4) to the air spring (2) is provided by means of switching elements (5), the method comprising the steps: - Determining or specifying a flow resistance (S) of the pipe (3) as a function of the pressure difference, - Measuring a spring air pressure (F) in the air spring (2) during operation, - Measuring a supply air pressure (V) of the compressed air supply (4) during operation, - Determining actuation times (A) of the switching elements (5) during operation, - Determining the air consumption (L) of the air spring (2) based on the determined flow resistance (S), the spring air pressure (F), the supply air pressure (V) and the actuation times (A) of the switching elements (5), - Outputting information about the air consumption (L).Furthermore, the invention comprises a device and a vehicle.
