A method for determining the mass of air in an electronically controllable air spring system for motor vehicles and apparatus for carrying out the method

摘要

The present invention relates to a method for determining the mass of air in an electronically controllable air spring system for motor vehicles with a supply container, wherein each vehicle wheel in each case an air spring damper unit is associated with. Moreover, the invention relates to a device for carrying out the method.In order to ensure at any moment which is in the air spring system to be able to determine the air mass is provided according to the invention that, in the air spring system (1) of the air pressure (p_total) , and is then determined in the air spring system (1) of the air mass (m_Air) is calculated. For this purpose, the volume (v_total) of the air spring system (1) by means of a previously carried out measurement or calculation of the volumes (v₂, V_Rr, V_Rl, V_Fr, V_Fl) of the storage container (2) and the air spring damper units (rl, rr, fl, fr) is determined.
