Zusammenfassung:A method of controlling an aspirator valve 11, 111 of a vacuum assisted braking system is provided that rapidly fully opens and closes the aspirator valve 11, 111 when an engine 6 of a motor vehicle 1 has been shut-down and the current conditions indicate that ice is likely to have formed in the aspirator valve 11, 111. The rapid opening and closing of the aspirator valve 11, 111 breaks up any ice that has built up thereby de-icing the aspirator valve 11, 111 and allowing the aspirator valve 11, 111 to function normally.
