Description

Technical Field

[0001] The present invention relates to a motor vehicle having a control device, the control device being configured to control at least one simulation device in a simulation mode so as to simulate at least one vehicle characteristic for at least one vehicle occupant. Background Art

[0002] Modern vehicles are usually quiet, comfortable and easy to operate. However, some vehicle users consider that such vehicles lack a certain degree of emotionality or a certain value of vehicle driving recognition. Therefore, for such users, old-fashioned cars, for example, are particularly attractive.

[0003] Therefore, it is attractive for many vehicle users if, in a normally quiet and comfortable vehicle, the originally unfavorable characteristics of older or very sporty vehicles, such as a certain operating noise of the power unit and / or a more perceptible driving or power unit noise, also occur as required or in a specific operating mode. Thereby, for example, the driver can be better integrated emotionally into the driving operation.

[0004] Therefore, document DE 10 2018 204 796 A1 proposes to simulate certain characteristics of other vehicles in a modern motor vehicle by appropriately controlling existing motor vehicle components, such as by adjusting the ignition timing and adjusting an adjustable chassis. However, the above measures may lead to disadvantages in terms of efficiency and driving power. Summary of the Invention

[0005] Therefore, an object of the present invention is to enable vehicle occupants to be better integrated into the driving operation, in particular by imitating vehicle characteristics known from older or especially sporty vehicles, and thus to give the driving operation a particular emotional color, but at the same time the above-mentioned disadvantages should be avoided.

[0006] According to the present invention, the object is achieved by a motor vehicle of the type described at the beginning, wherein, on the one hand, at least one seat and / or at least one foot space / footrest space and / or at least one armrest associated with a corresponding vehicle occupant includes at least one corresponding vibration device as a simulation device, and the control device is configured to control the corresponding vibration device in a simulation mode so as to simulate vehicle vibrations as a vehicle characteristic, and / or on the other hand, the motor vehicle includes at least one VR or AR glasses as a simulation device, and the control device is configured to control the VR or AR glasses in a simulation mode so as to simulate, for the corresponding vehicle occupant wearing the VR or AR glasses, a simulated interior impression different from the actual design of the vehicle interior as a vehicle characteristic.

[0007] According to the design of the motor vehicle according to the present invention, vehicle characteristics can be locally simulated for each vehicle occupant. By using local vibrations in the seat area of the respective vehicle occupant, or by specifically changing the interior impression in the field of vision of the respective vehicle occupant through AR or VR glasses, it is possible to dispense with changing the overall characteristics or overall impression of the motor vehicle. From this, the following multiple advantages are obtained:

[0008] Damage to the driving characteristics of the motor vehicle that may occur, for example, when configuring other parameters for the ignition time point or changing the chassis settings can be avoided. In addition, compared with exciting the entire vehicle vibration and using large-area image projection, the energy consumption for exciting local vibrations in the seat area of the respective vehicle occupant or changing the interior impression specific to the occupant is less, and it can also be implemented technically more simply, with less structural space occupied, and at lower cost. Finally, the method according to the present invention also enables at least one vehicle characteristic to be simulated only for one of the vehicle occupants, or different vehicle characteristics to be simulated, for example, for different vehicle occupants. This may be advantageous if, for example, the driver wants the driving experience of an old-fashioned car or a sports car, while the passenger wants a quiet and comfort-oriented driving experience, or vice versa.

[0009] The vibration device can in particular be used to simulate the characteristics of a power unit or a power train that is not actually installed in the motor vehicle. For example, vibrations transmitted into the interior due to power unit imbalance and / or small-sized power unit mounts or shock-absorbing devices can be simulated, especially the vibrations that occur in old-fashioned and / or sports vehicles, so that a specific haptic or tangible feedback for the operation of the power unit can be provided.

[0010] The vibration device and / or the VR or AR glasses can be fixedly installed in the motor vehicle or can also be designed as separate components, which can in particular be reversibly or temporarily arranged or placed in the motor vehicle in order to provide the motor vehicle according to the present invention. A common control device can be used for all the simulation devices. Alternatively, this control device can additionally also control other processes in the motor vehicle. However, local control devices in each vibration device or for groups of vibration devices and / or in the respective AR or VR glasses can also be used, and these local control devices can communicate, for example, wirelessly or also wiredly with the control device on the motor vehicle side in order to take into account motor vehicle parameters, for example, within the scope of the simulation.

[0011] The operation of the vibration device and / or the simulation of the interior impression via VR or AR glasses, as well as the activation of the simulation mode - which can then be manually activated, for example, by the respective occupant - can depend on the operating state of the motor vehicle. In particular, when operating the AR or VR glasses, especially when used by the driver, the AR or VR glasses can only be operated to simulate vehicle characteristics or change the interior impression when the motor vehicle is in a specified driving mode, for example, when using a specified automation level, and / or when the conditions for analyzing and evaluating the driver's behavior and / or state are met, for example, when the driver is neither distracted by complex driving tasks nor very fatigued.

[0012] VR and AR glasses are already widely known from other application areas and are therefore not explained in detail. With VR glasses (virtual reality glasses), the user, i.e., the vehicle occupant in this application, is usually visually isolated from the outside world by using at least one display in a closed glasses or closed helmet product. When using AR glasses (augmented reality glasses), on the other hand, only selectively superimposed on the actual environment, for example, by using a transparent display, gradually showing graphics by area, directly projecting onto the fundus of the eye, etc.

[0013] Therefore, in the simplest case, outside the simulation mode, the AR glasses can be in a non-operating state. Correspondingly, outside the simulation mode, the VR glasses can reproduce the environment as seen by the vehicle occupant without using the VR glasses through the display on the VR glasses. However, it is also possible to use the AR or VR glasses outside the simulation mode, for example, to gradually show information in the field of view of the vehicle occupant in the manner of a head-up display.

[0014] In the simulation mode, as will be explained in more detail later, specific areas of the motor vehicle can be overlaid or covered with a graphical display to simulate different interior impressions.

[0015] The simulation mode is particularly configurable so that the vehicle occupant can set, for example, via the menu system of the motor vehicle or also permanently via a driver profile or occupant profile adapted to, for example, the vehicle key or smartphone: when to use the simulation mode, which of the simulation functions explained above and / or below should be used by the simulation mode and / or how each simulation function should be parameterized. For example, depending on the configuration, different vehicle types can be simulated, the intensity of the vibration can be adapted, or other simulation functions, etc.

[0016] In particular, different parameterizations can be selected for different vehicle occupants, so that, for example, vibration is only simulated for a part of the vehicle occupants, or even different vibration modes can be given to different vehicle occupants simultaneously.

[0017] A vibration device arranged in the footwell or at least one vibration device arranged in the footwell can be configured to excite the vibration of a pedal arranged there and / or the vibration of at least one section of the floor surface. The vibration in the above-mentioned area is particularly suitable for simulating the vibration of the entire vehicle body at low cost.

[0018] A common vibration device can be used to excite the vibration of the entire pedal group arranged in the footwell, and / or at least one pedal there, in particular the accelerator pedal and / or the brake pedal, can have a vibration device coupled to the pedal or arranged on the pedal to excite the vibration of the pedal. In particular, the accelerator pedal, the brake pedal, and / or the clutch pedal can be excited to vibrate or include a vibration device.

[0019] The vibration device for exciting the floor surface can be integrated into the vehicle floor or installed there, for example. But it can also be designed as a foot mat or the like placed in the footwell, for example.

[0020] The corresponding at least one of the vibration devices or the vibration devices can be integrated into the backrest and / or the seat surface of the seat, in particular into the inner padding of the seat, and / or into the seat cover and / or the seat cushion, and can be configured to cause the contact surface of the seat that contacts the vehicle occupant to move relative to the seat base of the seat when the vehicle occupant is sitting on the corresponding seat. Thereby, vibration can be excited close to the body of the vehicle occupant, and thus only a small amount of energy consumption or a relatively small-sized vibration device is required to achieve a vibration that can be clearly felt by the vehicle occupant.

[0021] On the other hand, the corresponding at least one of the vibration devices or the vibration devices can be configured to move the entire corresponding seat relative to the vehicle body of the motor vehicle. This allows, for example, the use of standard seats without other modifications. For example, the movement of the entire seat and thus the introduction of vibration into the entire seat are achieved by adjusting the length of at least one length-adjustable seat support in an oscillating manner by an actuator.

[0022] The control device can be configured to control the operation of the vibration device in a simulation mode based on at least one driving parameter related to the driving operation of the motor vehicle. This would be appropriate, for example, in the case of simulating the characteristics of the power plant as described above, but additionally or alternatively, it is also appropriate for simulating the vibration of the vehicle body and / or the chassis (such as the vibration that may occur in an old motor vehicle under specific driving conditions, for example, at a specific driving speed). In particular, the control device can specify the intensity and / or frequency of the vibration based on the driving parameter.

[0023] The simulation device can be set to evaluate the pedal position of the pedal as a driving parameter, the lateral acceleration, the characteristics of the currently traveled section of the road, the current steering angle, the current or previous gearshift process, and / or the rotational speed of the power unit of the motor vehicle.

[0024] As already explained above, the vibrations generated are particularly intended to imitate the characteristics of another motor vehicle, in particular a sports or less modern motor vehicle. This can particularly relate to the natural vibrations of the steering device, the chassis, and / or the body and / or the vibrations of the powertrain, for example due to imbalance and / or torque fluctuations, which are usually manifested by the above parameters. Therefore, it is advantageous to consider at least a part of these parameters.

[0025] By considering the lateral acceleration, the vehicle behavior during dynamic cornering can be simulated. As the pedal position, the pedal positions of the accelerator pedal and / or the brake pedal are particularly evaluated. Additionally or alternatively, it may also be expedient to evaluate the pedal position of the clutch pedal in order to simulate the vehicle behavior during a gearshift process.

[0026] To obtain the above driving parameters or a part of these driving parameters, the sensor system of the motor vehicle can be used. For example, sensors can be used to detect the road conditions and / or the vehicle position can be determined first in order to determine the characteristics of the currently traveled section of the road, for example, based on the map data stored in the control device. The sensor system can also detect the driver's inputs on the steering wheel, the gearshift lever, and / or the pedals, which can be taken into account during the simulation.

[0027] Additionally, additional vibration devices can be used to particularly excite the vibrations of other surfaces that the vehicle occupants come into contact with during driving operation in order to simulate vehicle vibrations as vehicle characteristics. For example, corresponding additional vibration devices can be arranged on the steering wheel and / or the gearshift lever and / or the control rocker in order to excite the corresponding components to vibrate. Here, the vibration of the entire component can be caused or only the vibration of a surface section of the component surface can be caused.

[0028] The control device can be set to additionally control at least one additional vibration device of the motor vehicle in the simulation mode, which is arranged in or on the interior rearview mirror, in order to excite the vibration of the interior rearview mirror and / or the interior rearview mirror mirror. Additionally or alternatively, the control device can be set to additionally control at least one additional vibration device of the motor vehicle in the simulation mode, which is integrated into the display device for displaying at least one vehicle parameter, in order to excite the vibration of the pointer of the display device.

[0029] It is recognized within the scope of the present invention that, in addition to exciting vibrations in the footwell or seat area as described above, vibrations of the interior rearview mirror or its mirror surface and vibrations of the pointer of the display device are particularly suitable for also visually and inexpensively giving vehicle occupants the feeling of the overall vibration of the motor vehicle. This is particularly important when at least some vehicle occupants do not use VR or AR glasses to support the simulation.

[0030] The control device can be set to select at least one section in the display area of the VR or AR glasses based on a vehicle model that describes the position of the interior surfaces and / or operating elements and / or display devices, and based on transformation information that describes the position and / or orientation of the VR or AR glasses, and to display corresponding virtual vehicle components in the respective selected section in order to simulate the simulated interior impression as a vehicle characteristic. The presentation of the virtual vehicle components is thus recorded relative to the actually existing interior surfaces or operating elements and / or display structures. Thereby, the simulated interior impression appears particularly credible, and even if the relevant display is presented by virtual vehicle components, the relevant display can still be placed in the same position as the corresponding information presented outside the simulation mode or without using VR- or AR glasses.

[0031] The vehicle model can be fixedly preset based on a typical fixed and known configuration of the vehicle interior. However, it is also feasible that the simulation device is set to determine or adjust the vehicle model, for example, based on image data that can be obtained by an interior camera of the vehicle. For example, through feature recognition in the image data, the positions of the relevant interior surfaces or operating elements or display devices can be obtained, and / or it can be recognized, for example, whether an object arranged in the vehicle interior covers the relevant surface, so that no change in the presentation should be made in the covered area due to the use of VR or AR glasses.

[0032] The control device can be set to present a virtual display device as a virtual vehicle component or at least one of the virtual vehicle components, and the presentation of the virtual display device depends respectively on at least one driving parameter related to the driving operation of the motor vehicle. The driving parameter related to the driving operation of the motor vehicle can here be one of the driving parameters that will also be taken into account when controlling the vibration device as described above, but it can also be other driving parameters.

[0033] In particular, the virtual display device can be used to visualize the driving parameters for the driver. For example, such a virtual display device can be - in particular, simulated - a speedometer, an intake pressure display, a tachometer, etc. The virtual display device can particularly be faded in and displayed in the area where the driver would see the actual display device of the motor vehicle if not using VR or AR glasses. Thus, in the resulting interior impression, the existing display device can particularly be replaced by a differently designed, for example, older display device.

[0034] A motor vehicle can have a sound insulation system for reducing the driving noise and / or ambient noise entering the vehicle interior from the external area. In this case, the control device can be configured to, when switching from the normal operating mode to the simulation mode, control the actuators of the motor vehicle so as to displace at least one sound insulation component of the sound insulation system, thereby changing the reduction of the driving noise and / or ambient noise compared to the normal operating mode.

[0035] Within the adjustment range, the sound insulation component can in particular be displaced and / or deflected by the actuator. Thereby, a sound barrier is formed, and by opening the sound barrier, in the simulation mode, in the body section where the sound insulation component is located in the normal operating mode, a smaller reduction of the driving and / or ambient noise passing through this body section is obtained.

[0036] The corresponding sound insulation component can be arranged, for example, between the vehicle interior and the corresponding axle or the vehicle section located in front of or behind the vehicle interior. By opening such a sound barrier, thus, in the simulation mode, the tire rolling noise and wind noise can be more clearly perceived in the vehicle interior, thereby being able to imitate the acoustic impression of an old or sporty vehicle, which generally has a worse sound insulation effect compared to a modern, comfort-oriented vehicle.

[0037] Thereby, a particularly realistic imitation of the acoustic impression of other vehicles can be achieved at low cost compared to the simulation of the driving or ambient noise to be described below. However, depending on the specific design of the motor vehicle and the motor vehicle characteristics to be simulated, it is also advantageous that, in the simulation mode, in addition to opening the sound barrier, the noise simulation described in more detail below is additionally or alternatively used.

[0038] The control device of the simulation device can be configured to control at least one loudspeaker of the motor vehicle in the simulation mode. This can be used to simulate the sound generated by the simulated chassis and / or the simulated body. Additionally or alternatively, the loudspeaker can also be controlled to simulate the simulated sound impression of the driving noise and / or ambient noise entering the vehicle interior from the external area, which is different from the normal acoustic impression generated by reducing the driving noise and / or ambient noise through the said or a sound insulation system of the motor vehicle.

[0039] Preferably, a plurality of loudspeakers are controlled to generate a three-dimensional sound impression, wherein different sound sources can be located at different positions around the vehicle occupants in the virtual sound space. For example, a plurality of loudspeakers can be arranged around the vehicle occupants for this purpose, especially within an angle range of 360°. Here, for example, the loudspeakers of the multimedia system that already exist in the motor vehicle can be used, and these loudspeakers are usually originally scattered in the vehicle.

[0040] The sound source or sound impression mentioned can in particular be output in addition to the noise output of a simulated powertrain or power unit known per se.

[0041] The noise emitted by the loudspeaker, such as the noise position, volume and / or spectral composition and / or frequency and / or the change over time of at least one of the mentioned parameters, can depend on at least one of the following parameters: the pedal position of the accelerator pedal and / or the brake pedal, the lateral acceleration, the characteristics of the current driving section, the current steering angle, the current or previously existing gearshift process and / or the rotational speed of the power unit of the motor vehicle.

[0042] The simulated noise can be, for example, rattling, popping and / or whistling, eccentric rotation noise of the power unit, wind noise, ignition cut-off noise, simulated stone impact noise during wheel rotation, simulated raindrop noise and / or torsional and / or bending creaking noise of the vehicle body and / or of plastic parts mounted thereon. In particular, the loudspeaker can emit noises that the vehicle occupants may be familiar with from specific driving situations, especially noises from older, more sporty or generally emotionally particularly appealing vehicles.

[0043] The control device can also adjust the driving behavior of the vehicle in the simulation mode in order to, for example, provide the vehicle occupants with clearer or more direct feedback information about the interaction of the motor vehicle with the road.

[0044] The control device can be set to, in the simulation mode, control at least one chassis component of the active chassis of the motor vehicle and / or a seat belt tensioner as a function of the longitudinal and / or lateral acceleration of the motor vehicle.

[0045] By controlling the chassis components, the pitching of the motor vehicle during braking and / or acceleration and / or the roll due to lateral acceleration, especially during cornering, can be enhanced by actively tilting the motor vehicle. In this way, a softer suspension common in older vehicles can be particularly simulated. This active tilting can be achieved, for example, by appropriately controlling the air springs.

[0046] The seat belt tensioner can also be used to enrich the driving experience of the vehicle occupants. For example, the seat belt tensioner can be additionally tightened during acceleration and / or braking in order to make the acceleration more emotional. The higher pressure generated on the backs of the vehicle occupants may result in a felt acceleration that is greater than the actual acceleration.

[0047] The control device can be set to, in the simulation mode, intervene in the longitudinal and / or lateral control of the motor vehicle and / or change the parameterization of at least one vehicle system for longitudinal and / or lateral control and / or the parameterization of the chassis and / or the parameterization of the feedback device for feedback pedal force and / or steering force compared to the said or a normal operating mode.

[0048] For example, the steering and / or pedal characteristic curves can be adjusted to simulate the driving behavior of another vehicle. Additionally or alternatively, oversteering or understeering in a specific driving situation can be enhanced or attenuated, for example, by appropriately parameterizing at least one assistance system, such as a traction and / or stability control system and / or an anti-lock braking system, by active steering intervention and / or by torque vectoring between different axles and / or between the wheels of an axle.

[0049] Additionally or alternatively, for example, the spring and / or damper settings can be changed so that, for example, greater roll and / or pitch as occurs in older motor vehicles can be achieved by a softer chassis setting than in the normal operating mode, or so that the driving behavior of a sports vehicle can be approximated by a tighter chassis setting.

[0050] The feedback device can change the steering force and the pedal force, for example, by adjusting a return spring, deactivating the operation, or providing weaker assistance by an auxiliary actuator, or by applying an active reaction force by a simulation actuator. Thereby, for steering, for example, the servo steering mechanism can be deactivated or the absence of a servo steering mechanism can be simulated and / or the steering play can be adjusted. For the brake pedal, the brake booster can be deactivated or braking without a brake booster can be simulated. Preferably, the simulation interventions that may potentially lead to a worse controllability of the motor vehicle are only carried out when the current driving situation is not critical, and an automatic return to the normal operation can be made, for example, when a potentially critical future driving situation is detected.

[0051] The control device can be set to operate the fragrance device of the motor vehicle in a simulation mode to emit an aroma for simulating a fragrance as a vehicle characteristic. By emitting, for example, an oil smell, a tire wear smell, or other odors typical for older vehicles, such as a leather smell, the overall impression of the motor vehicle can be further adjusted.

[0052] Additionally or alternatively, the control device can be set to operate the ventilation device of the motor vehicle in a simulation mode according to the wind speed and / or the driving speed of the motor vehicle for simulating an air flow as a vehicle characteristic. Thereby, an impression can be given that the interior is less sealed, as is often the case, for example, in older vehicles. BRIEF DESCRIPTION OF THE DRAWINGS

[0053] Other advantages and details of the present invention result from the following embodiments and the drawings.

[0054] Figure 1 An embodiment of a motor vehicle according to the present invention is shown. DETAILED DESCRIPTION

[0055] Figure 1A motor vehicle 1 with a control device 2 is shown, the control device being set up to operate at least one simulation device in a simulation mode in order to simulate at least one vehicle characteristic for at least one vehicle occupant 3, 4. Here, the simulation mode is particularly used to simulate the following vehicle characteristics, which are usually associated by vehicle occupants 3, 4 with particularly characteristic, i.e. for example old-fashioned or sporty vehicles and are therefore suitable for increasing the emotional connection of the respective vehicle occupants 3, 4 to the vehicle operation.

[0056] As already explained in the overview section, it has been found that this can be achieved particularly advantageously by locally generating vibrations for each vehicle occupant 3, 4 in their seating area or on the surfaces they touch. In addition, it is particularly important for the driver to change the interior impression, for example by superimposing the actually existing instruments with instruments having an old-fashioned look.

[0057] To generate local vibrations, the seats 5, 6 and footwells 7, 8 of the shown motor vehicle 1 have a plurality of vibration devices 10 - 18, which can be operated by the control device 2 as simulation devices in order to simulate vehicle vibrations as a vehicle characteristic in the simulation mode. Additionally, in this example, for this purpose, vibration devices 54 for the same purpose are also arranged in the armrests 9.

[0058] The corresponding vibrations can, for example, simulate the imbalance of a non-existent power unit 55 and / or the natural vibrations of the chassis 47 and / or the body 28 that do not exist in the motor vehicle 1, just like the vibrations that vehicle occupants 3, 4 may know from other emotionally appealing motor vehicles. Since the vibrations are generated by separate vibration devices 10 - 18, 54 for different vehicle occupants 3, 4, the simulation of the vehicle characteristics can also be carried out only for one of the vehicle occupants 3, 4, or even different vehicle characteristics can be simulated for different vehicle occupants 3, 4.

[0059] The vibration device 10 is arranged on the pedal 21, in the example on the accelerator pedal, in order to excite the pedal 21 to vibrate. Alternatively, the entire pedal system can be excited to vibrate by a common vibration device. For the vehicle occupant 3, i.e. the driver, the vibration input via the pedal is particularly important if the vibrations of the entire motor vehicle 1 or the entire body 28 are to be simulated credibly.

[0060] Additionally, in this example, vibration devices 11, 12 are used in the respective footwells 7, 8, the vibration devices exciting at least one section 22, 23 of the floor surface there to vibrate. In this example, the vibration devices 11, 12 are designed as foot mats. But alternatively, the vibration devices can also be fixedly integrated into the vehicle floor. The impression of the vibrating body 28 is further enhanced by these vibration devices 11, 12.

[0061] To stimulate the vibration in seats 5 or 6, in this example, vibration devices 13, 14, 16, 17 are used, which are integrated into the corresponding backrests 24, 25 and seat surfaces 26, 27, and in this example are integrated into the inner padding there. By arranging the vibration devices 13, 14, 16, 17 close to the corresponding vehicle occupants 3, 4, a strong vibration impression can be generated on the vehicle occupants 3, 4 with only a relatively small vibration amplitude, whereby the performance requirements for the vibration devices 13, 14, 16, 17 are relatively low. Alternatively or additionally, in addition to integrating the vibration devices 13, 14, 16, 17 into the seat matrix or inner padding, the vibration devices can also be integrated into the seat cover and / or seat cushion of the seat.

[0062] In the example, vibration devices 15, 18 are also schematically shown, which can, for example, make the entire corresponding seat 5, 6 vibrate by oscillatingly adjusting the seat height. Generally, it is sufficient to use either the vibration devices 13, 14, 16, 17 or the vibration devices 15, 18.

[0063] As already elaborated, the vibrations of the various vibration devices 10 - 18, 54 generally aim to simulate the vibrations that occur in another motor vehicle, such as an old car or a sports car. Since such vibrations depend on the specific driving situation, in the example, the control device 2 evaluates various driving parameters and adapts the control mode for generating vibrations, such as the vibration frequency and / or amplitude used, based on these driving parameters.

[0064] In this example, at least the pedal position of the pedal 21 determined by the accelerator pedal sensor 30, the current steering angle detected by the steering angle sensor 31, and the rotational speed of the power unit 55 are considered as driving parameters. Additionally, the lateral acceleration is detected by the sensor 32 and is considered together with the characteristics of the current driving section (such as surface roughness) in order to particularly further improve the simulation of chassis and body vibrations.

[0065] In this example, the characteristics of the section are determined in such a way that first, the position of the motor vehicle 1 is determined by a position sensor 38, such as a GPS sensor, and based on the position of the motor vehicle, the characteristics of the section are determined based on the map data 39 stored in the control device 2. Alternatively or additionally, such characteristics can also be detected, for example, by an undetected sensor system of the motor vehicle 1, such as by means of a camera. Additionally, it can also be considered, for example, whether a gearshift process is currently occurring or has just occurred in the undetected transmission of the motor vehicle 1.

[0066] In this example, in addition to the vibration devices 10 - 18, 54, additional vibration devices are used to further enhance the impression of the motor vehicle 1 with vibrations for the occupants 3, 4. The vibration device 29 is arranged on the interior rearview mirror 30 to excite the vibration of the interior rearview mirror 30 or its mirror surface 31. The vibration device 32 is integrated into the display device 33, for example, integrated into a speedometer or a tachometer, and excites the vibration of the pointer 34 of the display device 33. Additionally, the steering wheel 56 also has a vibration device 57 to vibrate the surface of the steering wheel contacted by the driver as well.

[0067] Regarding the impression of the motor vehicle 1 on the occupants 3, 4, the visual interior impression is also very important. Thus, in this example, the AR glasses 19 are used as a simulation device, which is controlled by the control device 2 to simulate a simulated interior impression different from the actual design of the vehicle interior 20 by locally superimposing virtual vehicle components. For example, different colors and / or textures of the instrument panel can be presented thereby to simulate different interior materials, for example, or an actually existing display can be replaced with an older or generally differently designed display. As an alternative to using AR glasses, VR glasses can also be used, which image the vehicle interior and the vehicle environment from the perspective of the respective occupants 3, 4, in the example from the perspective of the driver, in the area where the presented content is not superimposed and changed accordingly. Such imaging can be detected, for example, by a camera of the VR glasses themselves or a vehicle - side camera.

[0068] To anchor the virtual vehicle components in the actual vehicle environment, in this example, the control device 2 uses a fixedly preset vehicle model 35, which describes the positions of the relevant interior surfaces, operating elements, and display devices. Based on this vehicle model and the transformation information that describes the position and orientation of the AR glasses 19 within the motor vehicle in a manner known per se, a section in the display area of the AR glasses can then be selected for the respective virtual vehicle component to be presented, and the virtual vehicle component is presented in this section such that the vehicle component appears to be in a fixed position in the motor vehicle 1 for the vehicle occupant 3. Thereby, specific objects can be replaced with virtual vehicle components for the vehicle occupant 3 wearing the AR glasses 19 in the interior 20 of the motor vehicle 1, thereby changing the interior impression.

[0069] In particular, a virtual display device, such as a simulated speedometer, can be presented as a virtual vehicle component. Since such a display device is intended to display driving parameters, such as the driving speed, the presented content depends on the respective driving parameters in this case, which can be detected by the control device 2 or provided to the control device by other devices of the motor vehicle 1.

[0070] In terms of the impression that the motor vehicle 1 gives to the corresponding vehicle occupants 3, 4, the acoustic background in the interior of the motor vehicle 1 is also very important. In the simulation mode, in particular, the characteristics of older or more sporty vehicles can be simulated, and the sound insulation of these vehicles is much worse compared to modern, comfort-oriented motor vehicles. However, the resulting greater driving noise and ambient noise sometimes give a very characteristic and charming feeling to the vehicle occupants 3, 4. Therefore, it would be appropriate to deliberately make the sound insulation systems 36, 37 worse in the simulation mode and / or replace the noise eliminated by the sound insulation systems 36, 37 with simulated noise.

[0071] Therefore, in this example, the motor vehicle 1 has actuators 40, 41, and when switching to the simulation mode, the sound insulation components 42, 43 of the sound insulation systems 36, 37 of the motor vehicle are displaced and / or deflected by the actuators in order to change the noise reduction of the driving noise and ambient noise compared to the normal operating mode. Therefore, the sound insulation panel in the motor vehicle 1 can be opened, so that, for example, compared to when not in the simulation mode, the rolling noise of the wheels of the motor vehicle 1 can be more clearly perceived in the interior 20 in the simulation mode.

[0072] Supplementally, speakers 44, 45 distributed in the interior of the motor vehicle 1 are used to change the acoustic impression of the driving operation for the vehicle occupants 3, 4. This is used in the example to simulate the noise generated by the simulated chassis, simulated body, and simulated power unit. In an alternative design, there is no such sound insulation panel, or alternatively, in addition to using the sound insulation panel, the speakers can additionally be controlled to simulate the simulated acoustic impression of the driving noise and / or ambient noise entering the vehicle interior 20 from the external area, and this simulated acoustic impression is different from the normal sound impression generated by the noise reduction of the driving noise and / or ambient noise by the said or one sound insulation system 36, 37 of the motor vehicle 1.

[0073] In order to further improve the simulation of other motor vehicles or further improve the vehicle occupants' integration into the driving operation and the emotional perceptibility of the driving operation, in the example, additional supplementary measures are also carried out in the simulation mode.

[0074] On the one hand, at least one chassis component of the active chassis 47 of the motor vehicle 1 is controlled according to the longitudinal and lateral accelerations of the motor vehicle 1 in order to simulate a less rigid chassis as often present in older motor vehicles by artificially enhancing the bumpiness or roll of the motor vehicle.

[0075] In addition, if this function is activated for the corresponding seat or vehicle occupants 3, 4, the corresponding seat belt tensioners 48, 49 are controlled during the acceleration process in order to pull the vehicle occupants 3, 4 more strongly in the direction of the backrest, thus creating a feeling of greater acceleration.

[0076] Furthermore, the control device can intervene in the longitudinal and / or lateral control of the motor vehicle 1, and / or, as already explained in more detail in the general part, change the parameterization of at least one longitudinal and / or lateral control of the vehicle system 46 and / or the parameterization of the chassis 47 and / or the parameterization of the feedback devices 50, 51 for feedback of pedal force and steering force compared to the described or a normal operating mode.

[0077] In order to also be able to imitate the smell of a less airtight interior and / or other vehicles, an aroma device 52 can be used to, for example, spread a leather smell in the interior, and / or the ventilation device 53 of the motor vehicle 1 can be controlled according to the wind speed and / or the driving speed for simulating the air flow in the interior.
