Patent number: 10493970Abstract: A method and device control at least one air dryer unit of an air supply system for the primary and auxiliary air supply of a vehicle. In the method and device, at least one compressor is driven by an associated electric motor that serves both for the primary air supply of a primary air tank and for the auxiliary air supply of an auxiliary air tank. Compressed air generated by the compressor is channeled over the at least one downstream air dryer unit so as to dry the compressed air generated by the compressor while the drying agent of the air dryer is regenerated with dried compressed air. During the auxiliary air supply, the air flow used for regenerating the at least one air dryer unit is reduced or suppressed.Type: GrantFiled: September 6, 2016Date of Patent: December 3, 2019Assignee: KNORR-BREMSE SYSTEME FÜR SCHIENENFAHRZEUGE GMBHInventors: Thomas Merkel, Peter Berger, Gert Assmann, Christian Urra, Angelicka Riedi, Philipp Gehrke
