In order to identify malfunctioning of a compressed air consumer circuit in a compressed air system for vehicles, the pressure in the compressed air circuits (26, 28, 30, 32, 34, 36) routinely measured and evaluated in an electronic control unit (84), which compares pressure values and/or detected negative pressure gradients of the compressed air circuits with a threshold value (S) and blocks the corresponding compressed air consumer circuit if the pressure values and/or the negative pressure gradients meet a circuit malfunction criterion. Said circuit malfunction criterion is met when the pressure values and/or the pressure gradients fall short of the corresponding threshold value over a given time that is identical or greater than the time tdyn of a dynamic pressure change or a dynamic pressure drop (t>=tdyn). |
