Description

The invention relates to a protective arrangement for protecting an occupant of a vehicle against motion sickness, wherein the protective arrangement comprises at least one sensor device and an evaluation device, wherein the at least one sensor device detects a future route of a section to be traveled by the vehicle and this as at least one sensor signal to the The evaluation device transmits, wherein the evaluation device evaluates the at least one sensor signal as at least one future vehicle movement, wherein the protection arrangement comprises a control device and at least one image output device with a display device for outputting at least one image display. The invention further relates to a vehicle with the protective device having the features of claim 11 and a method for protecting an occupant of a vehicle with the protective device from a motion sickness having the features of claim 12.

During a journey in a vehicle, it often happens that an occupant looking at a screen is affected by a motion sickness, e.g. suffers from nausea. A motion sickness is characterized in particular by a discrepancy in the perception of a movement sensation of the occupant due to the moving vehicle and an optical perception of the occupant, e.g. due to reading on an e-book or watching a video.

From the publication JP 2012/0009125 , which is probably the closest prior art, a monitor system with a monitor for a vehicle is known, wherein an image display on the monitor in response to movement of a body portion of an occupant is changed in order to prevent motion sickness.

The invention has for its object to propose a protective device to increase the well-being of an occupant of a vehicle and to avoid travel sickness of the occupant. This object is achieved by a protective arrangement having the features of claim 1, by a vehicle having the features of claim 11 and by a method for protecting the occupant having the features of claim 12. Preferred or advantageous embodiments of the invention will become apparent from the dependent claims, the following description and / or the accompanying figures.

A protective arrangement is proposed which is used to protect an occupant of a vehicle, e.g. of a passenger car, truck, rail vehicle or watercraft from travel sickness, e.g. from nausea, dizziness, headache or the like, is formed. Preferably, the passenger protection arrangement is suitable for a passenger seat or a rear seat of the vehicle. Optionally, in addition, the protective arrangement is suitable for a driver of the vehicle, in particular when the vehicle has highly automated functions. By the protection arrangement, typical phenomena of motion sickness, e.g. Nausea that is minimized or avoided by discrepancies in the perception of the occupant, especially when reading an e-book or watching videos in moving vehicles.

The protection arrangement has at least one sensor device and an evaluation device. The at least one sensor device is designed to detect a future course of the route, in particular a future trajectory of a route section to be traveled by the vehicle.

For example, the road section to be traveled, depending on the design of the vehicle as a road, rail or watercraft, may be a road section, rail section or waterway section. Preferably, the future route includes curves and / or bumps on the ground. In particular, the curves and / or unevenness of the future route have effects on a driving behavior and driving movements of the vehicle when it travels on the route section.

The at least one sensor device is designed, for example, as at least one optical camera system, as at least one radar system or lidar system and / or as at least one ultrasound system. Preferably, the at least one sensor device is designed for arrangement and / or integration in the vehicle. In particular, the at least one sensor device is a forward-looking sensor device which monitors the future route and detects the unevenness of the road before it actually acts in the vehicle when the section of road is traveled.

It is preferred that the at least one sensor device transmits the future route as at least one sensor signal to the evaluation device. The evaluation device evaluates the at least one sensor signal as at least one future vehicle movement. In particular, the evaluation device calculates, depending on the future course of the route detected by the at least one sensor device, how the vehicle will behave in its movement when driving on the future route section. For example, the future route may include height differences, in particular elevations or subsidence, and / or deviations directed to the side, in particular curves.

The protection arrangement has at least one image output device. The image output device may e.g. work analog or digital. It comprises a display device which is designed to output at least one image display. For example, the at least one image output device is designed as a vehicle-mounted image output device. Optionally, the on-vehicle image output device is a vehicle-integrated display or a vehicle-integrated display, e.g. around a headup display. Alternatively, the image output device may be formed as a mobile image output device. This is preferably carried by the occupant of the vehicle. For example, it can be designed as a tablet, smartphone or head-mounted display.

The protective device has a control device for controlling the image output device, in particular the display device. The control device controls the image output device, in particular the display device, to change an image information and / or an image position of the image display as a function of the at least one future vehicle movement. For this purpose, the evaluation device preferably transmits the evaluated and / or calculated future vehicle movement as an information signal to the control device.

It is preferred that the at least one image display is changed in its information content when the image output device is controlled by the control device by displaying other or further information on the display device. Alternatively or optionally in addition, the display device is changed when the image output device is actuated in its relative position in the vehicle and / or in its relative position relative to the occupant as a function of the at least one future vehicle movement.

Due to the forward-looking detection of the future route through the at least one sensor device, a suitable previous or timely correct calculation and / or evaluation by the evaluation device is possible. In particular, the change in the image information and / or image position of the image display by the control device can be implemented in time before the evaluated vehicle movement or in the correct time with the evaluated vehicle movement. It can thereby be advantageously achieved that a sensory conflict between an optical perception when the occupant is looking at the display device and a movement sensation when the vehicle leaves the future route route can be reduced. It can avoid the occurrence of motion sickness and increase the well-being of the occupant while driving.

In a preferred embodiment of the invention, vehicle parameters are stored and / or stored in the evaluation device. For example, the vehicle parameters include a speed of the vehicle, a suspension integrated in the vehicle, damping, and optionally additional parameters of adaptive systems of the vehicle. In particular, the evaluation device evaluates the at least one sensor signal as the detected future route as a function of the vehicle parameters as the at least one vehicle movement. In particular, the evaluation device calculates how the vehicle will behave on the basis of its vehicle parameters when driving on the future course of the route and which vehicle movements will act on the passengers.

It is possible within the scope of the invention that the change in the image information and / or image position is controlled such that it is implemented in the correct time and / or at the same time as driving on the route section and with the real vehicle movement generated thereby. In particular, the image information and / or image position of the image display can be changed in the correct time taking into account latent times of detection of the future route section by the at least one sensor device, the transmission of the at least one sensor signal to the evaluation device, the evaluation by the evaluation device and the output by the control device ,

However, it is particularly preferred within the scope of the invention for the control device to actuate the image output device to implement the at least one vehicle movement in the form of a position prediction, in particular a prediction formation. This means, in particular, that the image information and / or the image position of the image display is / are changed shortly before the actual driving on the route section and / or shortly before the occurrence of the real vehicle movement. Since the occupant can not grasp and anticipate the future route of the vehicle by looking at the display device, curves may come as a surprise to the occupant. This can be a trigger for travel sickness or even exacerbate it. The position prediction can be a slight look into the future, the inmates on the upcoming curve as early as possible. This ensures that the occupant is prepared for the respective following vehicle movement.

A preferred embodiment of the invention provides that the control device controls the image output device, in particular the display device, to dynamically, preferably in real time, change the image information and / or the image position of the image display as a function of the at least one vehicle movement. In particular, the image information and / or the image position of the image display is / are continuously changed and continuously adapted to the detected future route or to the at least one future vehicle movement.

It is particularly preferred that the at least one sensor device, the evaluation device, the control device and the display device are designed such that a detection, calculation and actuation time is sufficiently short that a corresponding time-correct or previous change of the image information and / or image position of the image display is possible. In particular, the evaluation device and the control device are in a digital data processing device of the protective device, e.g. in a computer or computer, integrated or connected to it.

It is particularly preferred that the change in the image information is implemented by an indication of a digital horizon profile. In particular, the horizon profile is displayed on the display device. In particular, the course of the horizon is adapted to and / or corresponds to a course of a real horizon, the real horizon being visible to the occupant when driving through the track section through an outer pane of the vehicle. In particular, this achieves that the occupant gets an information about the real horizon outside the vehicle when looking at the image display.

For example, the horizon history is output as a superimposed graphic on the image display, in particular on an original image display. The original image display is preferably the image display that the occupant is already looking at when superimposed by the digital horizon trace. In particular, the original image display is an image display freely selected by the occupant, such as e.g. a movie, a website or an e-book page. For example, the digital horizon trace is superimposed as a graphical reference in the form of a line on the original image display. In this case, the position, the course and / or the movement of the line on the original image display mimics a movement of a real horizon profile perceived by the occupant in the theoretical view through the outer pane, which situationally calculates correctly by the evaluation device on the basis of the future route course detected by the at least one sensor device becomes. For example, the horizon course can be called up and displayed in the form of a so-called app on the display device by the occupant.

Alternatively, it is preferred within the scope of the invention for the digital horizon profile to be implemented as a movement and / or displacement of the original image display of the display device. In particular, the video sequences currently being viewed by the occupant or the e-book page currently being read by the occupant are moved and / or shifted relative to the display device, so that only a portion of the video sequences or the e-book page may be dependent on the vehicle movement is visible on the display device. In particular, the original image display is moved analogously to the theoretically perceived movement of the real horizon profile in the display device.

Due to the superimposed display of the digital horizon or the movement and / or shift of the original image display, discrepancies between the various sensory channels of the occupant, e.g. between the optical and kinaesthetic channels of the occupant, minimized and a likelihood of the occurrence of motion sickness are reduced.

In a preferred embodiment of the invention, the change in the image position is implemented by a mechatronic movement of the image display device, in particular the display device. Preferably, the image display device, in particular the display device, is moved as a whole by a mechatronic adjusting device of the protective device. For example, the image display device, in particular the display device, is tilted and / or rotated shortly before a detected future cornering or parallel to the turning of the vehicle. When driving over a dome, the image display device may e.g. be raised, lowered when driving through a depression.

Another object of the invention relates to a vehicle with the protective device according to the previous description and / or according to claims 1-10. Furthermore, a method for protecting an occupant of a vehicle from motion sickness with a protective arrangement according to the previous description and / or according to claims 1-10 is proposed within the scope of the invention.
