    The invention relates to a driving safety training arrangement, comprising a memory with image data of at least one virtual danger situation, in particular of an obstacle, a display device for displaying an image generated from the image data or image sequence of a virtual danger situation in the field of vision Vehicle driver, wherein the display device comprises a transparent data glasses, in particular a known as "Augmented Reality" glasses or "Mixed Reality" glasses data glasses, or directed to the windshield of the vehicle projection device, and a triggering device for triggering the Einblendvorganges, according to the preamble of claim 1.
    Training systems of the conventional type use water walls or hinged obstacles that are actuated as soon as the vehicle has fallen below a certain distance to the relevant point. The disadvantage of such training systems is that they are hardly locally variable and are usually less realistic and cause high manufacturing and operating costs. In addition, for subsequent drivers who observe an ancestor, it is already apparent at which point, for example, a water wall or a hinged obstacle is actuated, whereby the surprise effect is lost.
    In the JP 2012 098 609 A and DE 10 2014 208 352 A1 training arrangements using "mixed reality" systems are described, wherein the fading of an image or a sequence of images of a virtual hazard situation in the field of vision of the driver on the basis of a position determination via a combination of an absolute position determination by means of GPS and a relative position determination by means of vehicle dynamics data. However, the practical testing of driving safety systems using mixed reality has proven that such a procedure is disadvantageous. The reason lies in the so-called "jitter" of GPS-determined data, ie in temporal clock jitter in the transmission of digital signals, and the consequent "jumping around" of the determined absolute position, even if the vehicle does not move. For conventional positioning applications, such as navigation applications, this blur is irrelevant to position detection because it is negligible and ultimately not noticeable to the user. However, if the detected position is the basis for calculating a displayed image sequence or a displayed image as in the context of "mixed reality" systems, this blurring causes the displayed images to "jump around", which irritates the driver to a headache and nausea can lead. In addition, it is difficult in known training arrangements based on GPS-based data to change simulated dangerous situations, since corresponding simulation systems must be reprogrammed or at least a software intervention must be made. This requires increased operating effort for the driving safety trainer and acceptance problems.
    The aim of the present invention is to eliminate these disadvantages and to provide a driving safety training arrangement, with the dangerous situations for the subject can be represented realistic closer, which has a better training effect and should be characterized by lower costs in production and operation. The training system should be versatile and flexible in its functionality.
    This object is achieved with the features of claim 1. Claim 1 relates to a driving safety training arrangement, comprising a memory with image data at least one virtual hazard situation, in particular an obstacle, a display device for displaying a / r image generated from the image data or image sequence of a virtual danger situation in the field of vision of the driver the display device comprises a transparent data goggles, in particular a data goggles known as Augmented Reality Goggles or Mixed Reality Goggles, or a projection device directed towards the windscreen of the vehicle, and a triggering device for triggering the insertion process. According to the invention, it is proposed that the triggering device comprises at least one, preferably a plurality of signal transmitters arranged along the driving safety route and a signal receiver arranged in the vehicle or in the display device for receiving a signal transmitted by the signal transmitter.
    When fading in, a virtual danger situation is superimposed on the real image that the vehicle driver sees through the transparent data glasses or the windshield. The display or projection of virtual hazard situations based on image data increases the functionality and the training effect. Thus, the danger situation to be displayed can be flexibly selected, modified and optimally adjusted to the training effect to be achieved by appropriate (image) data processing. Under virtual danger situation in particular the pictorial imitation-preferably including movement sequences-is understood a possible real danger situation.
    However, according to the invention, the fading in of images or image sequences does not take place on the basis of GPS-determined data, but on the basis of signal transmitters ("markers") which are arranged along the driving safety route. By using external transducers, the displayed image can be "stabilized" compared to GPS-based simulations. Only for an interaction with a displayed image (for example, the changed size representation of the displayed image depending on the driver's acceleration or braking, the simulation of a collision and the like) requires the knowledge of the instantaneous position of the vehicle based on GPS data and / or data the vehicle dynamics can be determined. According to the invention, the representation of the virtual danger situation can be stabilized by reference to its defined absolute position.
    The inventive features also bring the advantage that the simulated dangerous situations can be easily changed by simply changing the signal generator in position. In known systems, the simulation system must be reprogrammed, or at least perform a software intervention. In the inventive training arrangement a simple switching of the signal generator, which represents a lower operating effort for the driving safety trainer and rather corresponds to the already well-maintained operation of driving safety trainer. In addition, as mentioned above, a variability of the simulated dangerous situations important for the training effect, so it is very advantageous if changes in the simulated hazard situations can be made as simple as possible.
    Preferably, a plurality of different hazardous situations in the form of image data is stored in the (image data) memory. Depending on the training program to be completed and / or depending on the instructions generated by the triggering device certain dangerous situations can be selected and displayed by means of display device in the field of vision of the driver. The dangerous situations can be shown as static (i.e., non-changing) images. However, it is preferred that the hazardous situations be displayed dynamically (i.e., in a movie frame). As a result, movements (a deer, a pedestrian, etc.) can be imitated.
    The image data can be removed from the memory, further processed, linked to a sequence of images and changed or adjusted depending on external parameters (driving speed, ambient brightness, weather, orientation of the data glasses, etc.). The generation of (moving) images from the image data can thus also include a modification or adaptation of the data, for which purpose the training arrangement also comprises a data processing device.
    As "data glasses" is understood in the context of the present application, a device worn as a pair of glasses, which is able to display virtual, preferably three-dimensional content in the real world and to position these objects in relation to real objects in the room. Such data glasses are also referred to as "augmented reality" glasses or "mixed reality" glasses. A vehicle driver who has put on such a pair of glasses, see the environment as through normal eye-glasses, however, he (holographically virtual) objects can be displayed in the field of view.
    Virtual hazard situations could be, for example: "A pedestrian enters or crosses the road", "a deer jumps onto the road", "a cyclist falls", "a motorist disregards a priority board", "a truck loses cargo" etc. Even this exemplary list shows that the driver training can be made much closer to reality and more flexible than is the case in the prior art. However, holographic rendering could also simulate a smoke screen, or perception impaired by alcohol consumption.
    The triggering device is coupled directly or indirectly to the display device. With the triggering device, it is possible to trigger the fade or the fade-in process at a certain point of the driving safety route. As a result, a coupling of the display device with the driving safety distance is created. Thus, the particular nature of the track at certain points as a "background environment" for particularly well suited hazardous situations serve.
    The triggering device comprises according to the invention at least one, preferably a plurality along the driving safety distance arranged (n) signal generator and arranged in the vehicle or in the display device signal receiver for receiving a signal sent from the signal generator. The signal generator (s) are preferably arranged stationarily along the route and can be active or passive, ie actively send a signal or data to the signal receiver of the vehicle when passing through a vehicle, or be passively detected or read out by the signal receiver of the vehicle. In the latter case, "markers" are also used, such as QR codes. The signal generator can be arranged at the edge of the track or even further away, as long as they can be detected by the vehicle receiver. In the case of passive signal generators (markers), the relative position of the marker to a vehicle-side camera as a signal receiver can be calculated via the previously known size of the markers and the observed size and inclination. In the case of an active signal generator, the relative position to the signal receiver can be calculated, inter alia, by time stamps in the signal or by measured frequency changes (Doppler effect) or by signal strength changes. An arrangement of the signal generator in the vicinity of the route is advantageous, but in principle not absolutely necessary. In any case, the signal transmitters make it possible for a (specific) virtual dangerous situation to be "activated" at a specific point on the route. The stationary signal transmitter wirelessly communicates with the moving signal receiver and thereby emits radio signals. The signals may also be data signals containing image data.
    A preferred embodiment is characterized in that a first signal transmitter for a first dangerous situation coded and a second signal generator for a second, different from the first dangerous situation danger situation, preferably the first signal transmitter and the second signal transmitter at different locations along the Driving safety route are arranged. This realizes a course with a sequence of different dangerous situations. However, it is also possible or sometimes technically necessary for one or more signal transmitters to code for one and the same dangerous situation, for example when a starting and target position of an inserted, moving object must be defined by means of different signal transmitters.
    A preferred embodiment is characterized in that the signal sent by the signal generator is a trigger and / or coding signal or contains the image data of the relevant virtual hazard situation. This includes the possibilities that the signal transmitter only transmits a triggering signal for a specific dangerous situation and the actual image data are stored on the vehicle side or in the display device, or that the signal generator transmits the image data of the imported (image) sequence to the vehicle or display signal receiver transfers. The data size to be transmitted between transmitter and receiver can be kept small in the former case, and the further calculations and data breakdowns for the display device are carried out on the vehicle or display side.
    A preferred embodiment is characterized in that the memory is arranged in the vehicle or in the display device. The image data can be taken from the memory, further processed, linked to a sequence of images and changed or adjusted in dependence on external parameters (driving speed, ambient brightness, weather, orientation of the data glasses, etc.). As already mentioned, the (image data) memory could also be arranged in the signal generator or even in a central unit, which are connected to the signal generator (s).
    A preferred embodiment is further characterized by the fact that the data glasses comprise a holographic projection device for projecting the image or the image sequence onto at least one glass of the data glasses.
    A preferred embodiment is characterized in that a device for determining the reaction time of the vehicle driver is provided in dependence of the Einblendvorganges. This can be accomplished particularly simply because of the solution according to the invention, since triggering device and display device are in any case linked in terms of signal or data. Of course, the measurement of other parameters for driving safety is possible, such as pulse or pupil movement, or medical stress indicators such as blood pressure or skin temperature.
    A preferred embodiment is characterized in that the superimposed on the display device image of a virtual danger situation is variable depending on the driving speed. As a result, real dangerous situations are mimicked optimally, in particular, the perceptible size and perspective of objects or obstacles when approaching the vehicle can be adjusted accordingly.
    The training arrangement thus preferably comprises a speed sensor or is connected to a speed sensor of the vehicle, since the instantaneous speed is at least a decisive parameter for the realistic representation of virtual dangerous situations.
    In the following preferred embodiments of the invention will be described in more detail with reference to the drawing. It shows
    1 a driving safety training arrangement,
    2 shows a superposition of a virtual danger situation (runner) with the real environment, and
    Fig. 3 is a data glasses.
    Fig. 1 and 2 show a driving safety training arrangement 1 with a driving safety route 3, on which a subject in a vehicle 2 completed a driving safety training. The training arrangement 1 comprises a memory 4 with image data 5 of at least one virtual danger situation, in particular an obstacle, and a display device 6 for fading in an image of a virtual hazard situation generated by the image data 5 into the field of vision of the vehicle driver. For the subject results in a consequence of a superposition of a dangerous situation (in Fig. 2, a road crossing transporter) with the real environment.
    In the illustrated embodiment, the display device 6 is a transparent data glasses, in particular an "augmented reality" or "mixed reality" spectacle, through which the wearer can see the real environment, but in addition, fades in the field of view possible are. The data glasses may include a holographic projection device for projecting the image or image sequence. In an alternative embodiment, the display device could be a projection device directed at the windshield of the vehicle 2.
    The training system further comprises a triggering device 7 for triggering the insertion process of a virtual danger situation. In this case, an image or a sequence of images of a virtual danger situation by means of the display device 6 fades into the field of view of the driver, the blinding process is triggered by the triggering device 7. In the illustrated embodiment, the triggering device 7 comprises a plurality of stationary signal transmitters 8, 9 arranged along the driving safety route 3 and a signal receiver 10 arranged in the vehicle 2 or in the display device 6 (FIG. 3) for receiving a signal transmitted by the signal transmitter 8, 9. When approaching, i. when falling below a certain distance to the signal generator, 9, signalers, 9 and signal receiver 10 occur in unidirectional or bidirectional communication, so that as a result, the display of a dangerous situation is triggered by the display device.
    A first signal generator 8 could code for a first dangerous situation and a second signal generator 9 for a second, different from the first dangerous situation hazard situation. In this case, the first signal transmitter 8 and the second signal generator 9 are arranged at different locations along the driving safety route 3.
    The signalers 8, 9 preferably have a limited range, e.g. at most to the extent of twice the width of the driving safety distance 3. Outside this range, the signal from the signal generator can not be received by the signal receiver 10. The signal transmitted by the signal generator 8, 9 may be a triggering and / or coding signal (i.e., without image information regarding a virtual danger situation) or may already contain the image data of the at least one virtual danger situation.
    In Fig. 1, the memory 4 is arranged with the image data 5 in the vehicle 2. In the embodiment illustrated in FIG. 3, the memory 4 is arranged in the display device 6.
    The signal generator 8, 9 can be connected to each other by a central (data processing) unit 12. As a result, (signal) adjustments can be made to the signalers 8, 9, e.g. the image data (if provided by the signal generators), the range, the operating state (on-off), etc. may affect.
    The training arrangement shown in Fig. 1 also includes a device arranged in the vehicle 2 11 for determining the reaction time of the driver in response to the Einblendvorganges.
    It is further preferred if the displayed on the display device 6 image of a virtual danger situation in dependence on the driving speed and / or in dependence of the orientation of the data glasses is changeable and thus is not purely static. Basically, the visualized virtual hazard situation is preferably displayed in the form of moving pictures (i.e., in the manner of a movie).
    The inventive arrangement is characterized in comparison with conventional driving safety systems by lower operating costs and a better training effect, since the obstacles used are simulated in a conventional manner with water walls, but for subsequent drivers - who often watch the previous driver - no surprise represent. By contrast, the (holographic) projection is only visible to the driver with data glasses. In addition, the dangerous situations or obstacles can be varied more easily, either by data technology or by e.g. the signalers are arranged differently along the route.
