Abstract
A method and a device as well as a control unit for controlling at least one aggregate in a vehicle, the noise caused by the aggregate and/or at least one variable representing this noise being ascertained. In this connection, the passenger compartment noises in the vehicle are ascertained, or at least one variable representing these is ascertained. The noise caused by the aggregate and/or the variable representing this is correlated with the passenger compartment noises and/or the variable representing these. Finally, as a function of that, the control or a control signal for the aggregate is generated and/or adapted.
Claims13
A method for controlling at least one aggregate in a vehicle, comprising the steps of:
- ascertaining at least one of noise caused by the aggregate and at least one variable representing the noise caused by the aggregate;
- ascertaining at least one of noise in a passenger compartment of the vehicle and at least one variable representing the noise in the passenger compartment of the vehicle;
- correlating the at least one of the noise caused by the aggregate and the at least one variable representing the noise caused by the aggregate with the at least one of the noise in the passenger compartment and the at least one variable representing the noise in the passenger compartment;
- and
- one of generating and adapting a control signal for the aggregate as a function of the correlation so that the noise caused by the aggregate is one of overridden and partially overridden by the noise in the passenger compartment.
A device, comprising:
- a control unit configured to control at least one aggregate in a vehicle, the control unit including a first arrangement configured to ascertain at least one of noise caused by the aggregate and at least one variable representing the noise caused by the aggregate, a second arrangement configured to ascertain at least one of noise in a passenger compartment of the vehicle and at least one variable representing the noise in the passenger compartment of the vehicle, and a third arrangement configured to correlate the at least one of the noise caused by the aggregate and the at least one variable representing the noise caused by the aggregate with the at least one of the noise in the passenger compartment and the at least one variable representing the noise in the passenger compartment, wherein a control signal for the aggregate one of generated and adapted so that the noise caused by the aggregate is one of overridden and partially overridden by the noise in the passenger compartment.
A control unit for one of generating and adapting a control signal for at least one aggregate, wherein the control unit one of is connected to and includes a first arrangement configured to ascertain at least one of noise caused by the aggregate and at least one variable representing the noise caused by the aggregate, and the control unit one of is connected to and includes a second arrangement configured to ascertain at least one of noise in a passenger compartment of the vehicle and at least one variable representing the noise in the passenger compartment of the vehicle, and the control unit one of is connected to and includes a third arrangement configured to correlate the at least one of the noise caused by the aggregate and the at least one variable representing the noise caused by the aggregate with the at least one of the noise in the passenger compartment and the at least one variable representing the noise in the passenger compartment, the control unit one configured to one of generate and adapt the control signal for the aggregate as a function of the correlation so that the noise caused by the aggregate is one of overridden and partially overridden by the noise in the passenger compartment.
