A method for controlling the bringing-together of a fresh-air mass flow and a circulating air masses current

摘要

A method for controlling the bringing-together of a fresh-air mass flow (fl) and a circulating air masses current (ul) to a flow in the case of a motor vehicle - ventilation system, wherein a first control element (s1) in or on the end of a first channel (k1) for setting a requested fresh-air mass flow (fl) as the first part air masses current and a second control element (s2) in or on the end of a second channel (k2) for setting a requested circulating air masses, as the second part stream of air masses are arranged, and the air is then, by way of an at least partially common air channel (k) as flow a ansaugendem blower (g) is supplied, wherein at the same time a requested change of the fresh-air mass flow (fl) and of the circulating air masses current (ul) the first and second control element (s1, s2) are not driven at the same time, and wherein, in a requested increase in the fresh-air mass flow (fl) with simultaneous reduction of the circulating air masses current (ul) in a first step, only the first control element (s1) for setting of the requested fresh-air mass flow (fl) is controlled and, after a predetermined first time interval (δt1) according to the beginning of the driving of the first control element (s1) for setting of the requested fresh-air mass flow (fl) the second control element (s2) for setting of the requested circulating air masses current (ul) is controlled.
