The system has a control unit which is coupled to a sensor system and/or a navigation system, a vehicle seat system, and/or a display unit for receiving and/or outputting signals. The control unit is designed to generate seat adjustment signals and/or display signals depending on received surroundings data and/or vehicle component data. ## Claims ### Claim 1 A system for reducing motion sickness symptoms in operation of a vehicle, comprising: at least one of a sensor system or a navigation system; a vehicle seat system; a display unit; a control unit coupled to the at least one of the sensor system or the navigation system, the control unit being further coupled to the vehicle seat system and to the display unit, wherein: the sensor system and the navigation system are configured so as to receive surroundings data and vehicle component data of the vehicle from which movements of the vehicle result and to transmit the surroundings data and the vehicle component data to the control unit, the vehicle seat system is configured so as to receive seat adjustment signals from the control unit and to adjust at least one vehicle seat of the vehicle in accordance with the received seat adjustment signals, the display unit is configured so as to receive display signals from the control unit and to display the display signals, the control unit is configured so as to generate seat adjustment signals and display signals depending on the received surroundings data and vehicle component data, generating the seat adjustment signals comprises: determining first acceleration forces that would act on a vehicle occupant sitting on a vehicle seat due to the movements of the vehicle using the surroundings data and vehicle component data; and determining seat adjustment signals that are designed such that they bring about second acceleration forces that counteract the first acceleration forces for the vehicle occupant after adjusting the vehicle seat in accordance with these seat adjustment signals; and generating the display signals comprises: determining acceleration forces actually acting on the vehicle occupant on the vehicle seat adjusted in accordance with the seat adjustment signals; and determining display signals that are designed such that they bring about a sensory perception, congruent with the acceleration forces actually acting on the vehicle occupant on the vehicle seat adjusted in accordance with the seat adjustment signals. ### Claim 2 (depends on 1) The system according to claim 1, wherein at least one of: the control unit is further configured so as to generate the seat adjustment signals only for a vehicle seat whose orientation deviates from a direction of travel of the vehicle, the vehicle seat system is further configured so as to receive seat adjustment signals from the control unit only for a vehicle seat whose orientation deviates from the direction of travel of the vehicle, and the vehicle seat system is further configured so as to adjust only a vehicle seat whose orientation deviates from the direction of travel of the vehicle in accordance with the received seat adjustment signals. ### Claim 3 (depends on 1) The system according to claim 1, wherein the display signals comprise at least one of: artificial optical surroundings, wherein the artificial optical surroundings are displayed outside a viewing axis of the vehicle occupant and within an individual field of view of the vehicle occupant; artificial acoustic surroundings; holographic image elements; air flows; or haptic effects on the vehicle occupant, including at least one of massage effects or vibration effects. ### Claim 4 (depends on 1) The system according to claim 1, wherein the display signals are varied depending on at least one of surroundings of the vehicle, a time of day, or weather. ### Claim 5 (depends on 1) The system according to claim 1, wherein the display unit is configured such that displayed display signals are not visible at a same time to all vehicle occupants. ### Claim 6 (depends on 1) The system according to claim 1, wherein the second acceleration forces are large enough that the first acceleration forces and the second acceleration forces cancel one another out. ### Claim 7 (depends on 1) The system according to claim 1, wherein the system further comprises a warning unit that is coupled to the control unit, and wherein the control unit is further configured so as to use the received surroundings data and vehicle component data to determine whether the vehicle will have an unavoidable crash within a predefined duration and, in an event that the vehicle will have an unavoidable crash within the predefined duration, to prompt the warning unit to output warning signals that are designed to bring about reflex protective reactions in vehicle occupants. ### Claim 8 (depends on 1) The system according to claim 1, wherein the display unit is further configured such that the displayed display signals are in each case visible only to one vehicle occupant, wherein the system further comprises a monitoring unit that is coupled to the control unit in order to receive and emit signals and is configured so as to monitor whether a vehicle occupant is capable of perceiving a situation external to the vehicle, and to emit a positive monitoring signal to the control unit if upon determining that the one vehicle occupant is capable of perceiving the situation external to the vehicle, and to emit a negative monitoring signal to the control unit if upon determining that the respective vehicle occupant is incapable of perceiving the situation external to the vehicle, and wherein the control unit is further configured so as to at least one of: generate seat adjustment signals for the vehicle seat on which the one vehicle occupant is sitting, or generate display signals for the respective vehicle occupant only upon determining that a negative monitoring signal is present. ### Claim 9 (depends on 1) The system according to claim 1, wherein the system further comprises a monitoring unit that is coupled to the control unit in order to receive and emit signals and is configured so as to monitor whether a vehicle occupant is capable of perceiving a situation external to the vehicle, and to emit a positive monitoring signal to the control unit upon determining that the vehicle occupant is capable of perceiving the situation external to the vehicle, and to emit a negative monitoring signal to the control unit upon determining that the vehicle occupant is incapable of perceiving the situation external to the vehicle, wherein the vehicle seat system is further configured so as to at least one of: receive seat adjustment signals for the vehicle seat on which the respective vehicle occupant is sitting, or adjust the vehicle seat on which the respective vehicle occupant is sitting only upon determining that a negative monitoring signal is present, and wherein the display unit is further configured so as to at least one of receive or to display signals for the respective vehicle occupant only if upon determining that a negative monitoring signal is present. ### Claim 10 (depends on 1) A vehicle comprising a system according to claim 1. ### Claim 11 A method for reducing motion sickness symptoms, the method comprising: receiving surroundings data and vehicle component data of a vehicle from which movements of the vehicle result; generating seat adjustment signals and display signals depending on the received surroundings data and vehicle component data; adjusting at least one vehicle seat of the vehicle in accordance with the seat adjustment signals; and displaying the display signals; wherein generating the seat adjustment signals comprises: determining first acceleration forces that would act on a vehicle occupant sitting on a vehicle seat due to the movements of the vehicle using the surroundings data and vehicle component data; and determining seat adjustment signals that are designed such that they bring about second acceleration forces that counteract the first acceleration forces for the vehicle occupant after adjusting the vehicle seat in accordance with these seat adjustment signals; and wherein generating the display signals comprises: determining acceleration forces actually acting on the vehicle occupant on the vehicle seat adjusted in accordance with the seat adjustment signals; and determining display signals that are designed such that they bring about a sensory perception, congruent with the acceleration forces actually acting on the vehicle occupant on the vehicle seat adjusted in accordance with the seat adjustment signals.
