Connection, connection system, and method for connecting at least two components

1. A connection system configured to connect at least two components of a motor vehicle, comprising:

at least one control unit; and

at least one connection unit which is operatively coupled to the at least one control unit, and which is arranged on the at least two components, wherein

the at least two components have at least one connection therebetween,

the at least one connection has at least one connection surface,

at least one property of the connection unit is variable in a targeted manner in such a way that an adhesion property of the connecting surface is setable,

the at least one control unit is configured to load the at least one connection unit of the at least one connection with at least one external influencing variable in a targeted manner in such a way that the at least one property of the connection unit is variable in a targeted manner in order to set the adhesion of the at least one connection surface of the at least one connection unit, and

the at least one control unit is configured to load the at least one connection unit in a targeted manner with the at least one external influencing variable in a manner that depends on a detected instantaneous acoustic behavior of the motor vehicle.

2. The connection according to claim 1 , wherein the at least one control unit is configured to load the at least one connection unit in a targeted manner with the at least one external influencing variable in a manner that depends on a detected instantaneous or a predetermined driving state of the motor vehicle.

3. A method for the connection of at least two components of a motor vehicle, comprising:

arranging at least one connection unit on one of the at least two components, which are not connected to one another, which connection unit providing at least one connection surface, and by which connection unit at least one property is variable by way of targeted loading with at least one external influencing variable in such a way that an adhesion of the connection surface is setable;

decreasing the adhesion capability of the connection surface to a predefined first level by way of targeted loading of the connection unit with a predefined first value of the at least one external influencing variable;

positioning the at least two components which are to be connected to one another in their respective connection positions relative to one another in such a way that the connection surface makes direct contact with the respective other component; and

increasing the adhesion capability of the connection surface to a predefined second level, which is greater than the first level, by way of targeted loading of the at least one connection unit with a predefined second value of the at least one external influencing variable, the second value differing from the first value, wherein

after the connection of the components to one another is carried out, the at least one connection unit is loaded in a targeted manner with the at least one external influencing variable in a manner which is dependent on a detected instantaneous acoustic behavior of the motor vehicle.

4. The method according to claim 3 , wherein the targeted loading of the at least one connection unit with a predefined first value of the at least one external influencing variable takes place in an active manner, and the targeted loading of the at least one connection unit with a predefined second value of the at least one external influencing variable takes place in a passive manner.

5. The method according to claim 4 , wherein after the connection of the components to one another is carried out, the connection unit is loaded in a targeted manner with the at least one external influencing variable in a manner which is dependent on a detected instantaneous or a predefined driving state of the motor vehicle.
