Abstract:
1. A control device of a motor vehicle which has a noise transmission system and an exhaust system, wherein the noise transmission system has, for manipulating an interior noise of the motor vehicle, at least one intake noise transmission device which is configured to be coupled via a first tubular connecting element to an air intake pipe leading to an internal combustion engine, the first tubular connecting element being assigned a switchable shut-off device, and which is configured to be coupled via a second tubular connecting element to a vehicle interior, wherein the exhaust system has at least one switchable shut-off device for manipulating an exterior noise of the motor vehicle, and wherein the control device manipulates the operation of the noise transmission system and of the exhaust system jointly as a function of an actuation of a common operating element by a driver of the motor vehicle, wherein in a first state of actuation of the operating element, said control device determines characteristic maps for the operation of the shut-off devices of the noise transmission system and of the exhaust system so as to yield a relatively low interior noise level and relatively low exterior noise level, and wherein in a second state of actuation of the operating element, said control device determines characteristic maps for the operation of the shut-off devices of the noise transmission system and of the exhaust system so as to yield a relatively high interior noise level and relatively high exterior noise level, wherein the noise transmission system has a resonator device which interacts with the intake noise transmission device and which is configured to be coupled via a third tubular connecting element to the air intake pipe which leads to the internal combustion engine, the third tubular connecting element being assigned a switchable shut-off device, wherein the control device automatically actuates the shut-off devices of the intake noise transmission device, of the resonator device and of the exhaust system on the basis of the characteristic maps.
