An anti-noise system for influencing exhaust noises propagating through a multi-flow exhaust system includes a controllerand at least one actuator. The at least one actuator is disposed in a sound generator, connected to the controllerfor receiving control signals, and adapted to generate sound inside the sound generator. The sound generatoris connectable to at least two exhaust tractsof the multi-flow exhaust system of the vehicle simultaneously. The controlleris configured to generate a control signal that prompts the at least one actuator disposed in the sound generatorto cancel sound inside the at least two exhaust tractsof the vehicle's multi-flow exhaust system at least in part and preferably completely.

System for influencing exhaust noise in a multi-flow exhaust system

A road vehicle () has a drive unit () for driving the vehicle (), a drive unit control device () for driving the drive unit () and at least one sound generator (), which has at least one electroacoustic converter (). The sound generator () has an emission pipe (), which connects the sound generator () acoustically and fluidically directly with an emission chamber (). The an emission chamber () emits the sound generated by the converter () during the operation of the sound generator (). Increased reliability of operation is achieved if a generator control device () is coupled with the drive unit control device () for driving the converter () and the generator control device () drives the converter () as a function of the current operating state of the drive unit ().

Road vehicle

An exhaust system, for a vehicle driven by an internal combustion engine, has a system for removing condensate () that includes a first line section () for fluid connection with exhaust gas (), at least one second line section () for fluid connection with exhaust gas (), and at least one suction line (). The suction line () is disposed between the bottom () of the at least one second line section () and the first line section (), and includes an opening () configured to be passed over by exhaust gas () passing through the first line section ().
