Definitions

  • the present invention relates to a method and apparatus for displaying traffic sign information, to a corresponding device and to a corresponding computer program product.
  • the present invention provides a method for displaying traffic sign information, furthermore a device which uses this method and finally a corresponding computer program product according to the main claims.
  • Advantageous embodiments emerge from the respective subclaims and the following description.
  • a head-up display is a system that displays information directly into the driver's field of vision.
  • the driver in a head-down display or in the instrument cluster in the vehicle, the driver must look down to see important indications such as speed or directional guidance.
  • the data is projected directly onto the windshield on a head-up display, it gives the driver the impression that the image is about two and a half meters away from him above the engine hood floats. This has the advantage that the driver no longer has to avert his gaze from the traffic.
  • Head-up displays can also display information directly in the real image. These displays are in common usage contact analogue or
  • Augmented Reaiity called Head-up Displays.
  • the driver can with the help of this technique z.
  • navigation instructions are given by the colored road in front of him to the horizon marked. Also, navigation instructions can be displayed, which lie as arrows directly on the road. Even traffic lanes or vehicles detected by the ACC system, ie an adaptive cruise control system, can be displayed directly in the driver's field of vision. The image is generated in an accommodation-free distance of approx. 10 m to the horizon, the virtual field of view of the head-up display.
  • a contact-analogue head-up display can be used to project the driver an indication of a warning relating to a section of the route to be driven directly into his field of vision.
  • the driver can be projected an indication of a bid or prohibition relating to the route section to be driven directly into his field of vision.
  • the projection can take place in such a way that the reference to a position is embedded in the real environment of the vehicle, which makes it easier for the driver to record and understand the message.
  • the indication can be projected directly onto a surface of a section of a roadway which is visible to the driver.
  • the hint can be projected to a position at which the hint is valid.
  • the message can be projected by the head-up display into contact with the position. From the driver's point of view, the note appears as if it were actually in the real environment at the position. If the vehicle continues to approach the position, the reference from the head-up display can continue to be projected into the position in contact-analogous manner, taking into account the reduced distance.
  • the driver thus has the feeling that he is approaching the hint, as is the case with a real reference, for example, applied to the road surface.
  • the contact analog indication can be used together with a non- joranaiog be deployed in the field of view of the driver projected status information field.
  • the contact-analog projected indication and the non-contact-analogous projected status information field may be projected into the driver's field of view such that the proximity-projected indication migrates into the status information field as the vehicle approaches the location of the contact-analog indication from the driver's point of view, and finally from the status information field is taken over there and, as long as the note is valid, remains as a non-contact-analogous hint.
  • the driver of the vehicle did not have time to record the contact analog message, he is made aware by changing the contact analog indication to the non-contact analog status information field that there is a change in the display of the status information field. Due to the subsequent permanent display of the hint as part of the status information field, the driver has enough time to record the information content of the hint.
  • a method for displaying traffic sign information for a driver of a vehicle comprises the following steps:
  • the vehicle may be a motor vehicle, for example a passenger car or a lorry.
  • the vehicle may have a projection device, for example in the form of a head-up display.
  • the projection device can be designed to project both a contact-analog and a non-contact-analogue display into a field of vision of the driver of the vehicle.
  • the indication signal may be an electrical signal.
  • the display signal may be suitable for controlling the projection device in such a way that the projection device projects the traffic sign information into the driver's field of view as a contact-analogous virtual representation.
  • the traffic sign information may contain information of a danger which indicates a risk or includes information on a mandatory sign indicating a bid or prohibition.
  • the traffic sign information may be displayed in the form of a corresponding traffic sign or a pictogram resembling a traffic sign.
  • the traffic sign information may indicate a speed limit and be presented in the form of a speed limit sign.
  • the route may be a planned course of a section of road ahead of the vehicle. Data regarding the route can be output from a navigation system of the vehicle.
  • the beginning of the validity period of the traffic sign information may be determined based on stored data.
  • the data relating to the validity range can be stored in a memory device, for example in the form of a digital map, in the vehicle or can be retrieved via an interface from a vehicle-external memory device.
  • the position may indicate a real location located at the beginning of the scope.
  • the position can be arranged directly at the beginning, shortly before the beginning or shortly after the beginning of the validity range.
  • the position may indicate a location on a roadway to be traveled by the vehicle.
  • the position may identify a location that is located next to the roadway to be traveled.
  • the traffic sign information can be displayed as position-related contact-analog virtual representation with different extents. If the distance between the vehicle and the position changes, a new indication signal can be generated to ensure that the traffic sign information continues to be displayed at the position from the driver's point of view.
  • the different display signals can be generated one after the other. For example, a new indication signal may be generated when a predetermined time period has elapsed or a predetermined distance traveled after a previous indication signal. Apart from the extent, the shape and appearance of the traffic sign information in the different display signals may be the same. Due to the different borrowed expansions, the traffic sign information appears from the point of view of Driver at different distances to the position in different sizes.
  • the different display signals may be generated such that the smaller the distances between the vehicle and the position, the smaller the distances between the position-related contact-analog virtual representations in a first distance range, and the smaller in a second distance range, depending becomes smaller the distances between the vehicle and the position, wherein the distances covered by the second distance range are smaller than the distances covered by the first distance range.

  • the status information field may be constantly displayed at the same position with respect to a reference point on the vehicle from the driver's point of view.
  • the method may include a step of generating a further indication signal for displaying the traffic sign information as a non-contact analog virtual representation within a display area of the status information field. Apart from the non-contact analog representation, the

  • the method may include a step of generating a further display signal for displaying a preceding traffic signal information as a non-contact analog virtual representation within the display area of the status information field.
  • the step of generating the further indication signal can be carried out in addition to the step of generating the indication signal, so that the non-contact-analog representation of the previous traffic sign information takes place in parallel to the contact-analog representation of the new traffic sign information.
