Control unit for controlling exhaust flap actuators and multi-flow exhaust systems

摘要

Control unit (350) for a multi-flow exhaust system (100) for a vehicle, the multi-flow exhaust system (100) comprising a first and a second exhaust duct (110, 120) which are set up to remove exhaust gases from an internal combustion engine of the vehicle from the vehicle conduct; the first and second exhaust gas ducts (110, 120) each having a primary path (113, 123) and a secondary path (112, 122); - a first and a second exhaust gas flap (111, 121) for the first and second exhaust gas duct ( 110, 120); wherein the exhaust flaps (111, 121) are set up to open or close the respective primary path (113, 123); and - a silencer (101) which is set up to acoustically attenuate the first and second exhaust gas ducts (110, 120), the primary paths (113, 123) having a different sound attenuation compared to the secondary paths (112, 122); and wherein the control unit (350) is set up to open or close the first and the second exhaust flaps (111, 121) with a time delay, a time interval between the opening or the closing of the first and second exhaust flaps (111, 121) being the same as or greater than a predefined time threshold.
