Abstract: A method for controlling at least two mechanical oscillators, more particularly in a motor vehicle, where each oscillator oscillates at a frequency during operation and where the frequency can be controlled by the power applied to the oscillators, includes arranging a single sound transducer at a distance from the oscillators and capturing an electrical signal, where the electrical signal is subjected to a Fourier transform and thus a Fourier spectrum is determined. The frequency of each oscillator is determined from extreme values of the Fourier spectrum.

Abstract: A method for controlling vehicle functions to increase the well-being and/or to increase the attention of at least one vehicle user in a vehicle. A number of vehicle functions are activated when at least one specific user menu is selected. Here, a lead function assigned to the user menu from the number of vehicle functions is predetermined in each case and the time and content processes of the other vehicle functions assigned to the user menu are coordinated with respect to the lead function.

Abstract: A method for operating a seat system, where the seat system includes a vehicle seat having a plurality of controllable moveable elements integrated into a seat cushion that forms a seat surface and/or into a seat back, includes prompting, during an activated muscle training program, a user on the vehicle seat to exert a pressure with a specific body region of the user on a predetermined region of the vehicle seat in which at least one of the plurality of controllable moveable element is arranged and determining a local and a temporal deviation between a pressure exerted by the user as an input signal and a specification as an output signal.

Abstract: A method for operating a vehicle where at least one comfort function is offered to at least one vehicle user for activation. The at least one comfort function is offered to the at least one vehicle user for activation after a start of an electrical charging process of at least one energy storage device of the vehicle. The comfort function is offered to the vehicle user depending on an expected necessary charging time of the electrical charging process of the energy storage device of the vehicle.

Abstract: A method for operating a motor vehicle having a seat arranged in an interior of the motor vehicle for a passenger, into which seat at least one oscillator for transmitting oscillations to the passenger's body is integrated, and having a sound system for acoustic sound reproduction in the interior, includes determining the passenger's passenger state and selecting and reproducing a type of a sound sequence that is associated with the passenger's state via the sound system. The at least one such oscillator is activated on the basis of the selected type of sound sequence. In this way, convenience functions and/or assistance systems of the motor vehicle can be improved.

Abstract: An opportunity for stimulating an occupant of a vehicle seat in order to activate his/her body and mind is provided. For this purpose, a vehicle seat system includes a vehicle seat with a massage device for influencing the seat contour integrated into the seat back and a control unit for controlling the massage device. The system also includes a communication device that can transmit at least one instruction to an occupant of the vehicle seat in response to the control of the massage device.
