Definitions

  • the invention relates to a device for displaying information for an occupant of a motor vehicle and a corresponding system, method and computer program.
  • head-up display devices for displaying information in vehicles.
  • information for example the current driving speed
  • These display devices usually have a projector that throws the light emitted by the display against the windshield, which acts as a combiner and reflects the light, thus providing a virtual image in front of the windshield that is visible to the driver.
  • a disadvantage of such systems is that part of the image behind the windshield is always at least partially covered, so that relevant information from the image behind the windshield is difficult for a driver to perceive.
  • the driver's attention and line of sight are directed to the projection onto the windshield. The driver's attention to information from the image behind the windshield is reduced.
  • Document DE 198 13 300 A1 relates to a display device, in particular a passenger information system for motor vehicles, with a device for projecting at least one virtual image in front of a windshield of the motor vehicle. Provision is made for a position of the at least one virtual image in front of the windshield to be variable as a function of at least one driving condition parameter.
  • the disadvantage here is that only one driving condition parameter is taken into account, a viewing direction of the driver and the condition of the roadway are not taken into account. As a result, for example, a pothole can be covered by the virtual image and only poorly or not at all recognized by the driver, which leads to an increased risk of an accident.
  • Document DE 103 36 329 A1 relates to a method, a device and a processing unit for improving visibility in a motor vehicle. From the image of the area around the motor vehicle, which records a camera of the motor vehicle, a Image section provided, the size of the image section and additionally or alternatively the position of the image section within the image depending on the course of the road and / or the current and / or desired by the driver direction of travel of the motor vehicle is set.
  • the disadvantage here is that only a predetermined trajectory of the motor vehicle is taken into account. With the teaching disclosed, it is not possible for the driver to direct his gaze in a targeted manner, for example in the direction of the source of danger when a source of danger has been identified. In addition, it cannot be guaranteed that the driver will capture the image section immediately, since the driver's eye position or viewing direction is not determined.
  • the publication DE 102007 035 505 A1 describes a motor vehicle with a head-up display for displaying information, the information displayed by the head-up display being visible from a spatial element inside the motor vehicle, with an adjustment device for adjusting the position of the Spatial element with a detection device for detecting the position of the eyes or the head of a driver of the motor vehicle, with a control device which is set up and coupled to the adjusting device and the detection device in such a way that the position of the spatial element depends on the detected position of the eyes or the Head of a driver is adjusted.
  • the disadvantage here is that only the driver's eye position is recorded in order to achieve improved visibility of the information. A transmission of further information through the position of the notice on the windscreen and/or a subtle directing of the driver's gaze is not achieved.
  • the published application DE 102018 004662 A1 relates to an optical detection system, in particular for a driver assistance system for detecting the area of the roadway/driving trajectory in the direction of travel, with a detection area for recording a section of the surroundings, comprising an image sensor chip which has a specific maximum number of pixels, with the recording of the environmental image, a specific number of pixels is active in a pixel area of the image receiver chip to be evaluated, wherein the maximum number of pixels of the image receiver chip is greater than the number of pixels of the pixel area to be evaluated and wherein the detection area is variable, the variation and/or alignment of the detection area on the driving trajectory ahead takes place by changing the pixel area to be evaluated on the image receiver chip, with a) control parameters supplied for this purpose serving as input parameters, which originate from other systems located in the motor vehicle en and/or are made available by means of these systems, and/or b) self-determined control parameters as input parameters are used, which originate from the optical detection system and/or are made available by means of the optical detection system.
  • the invention is now based on the object of creating a device for displaying information for an occupant of a motor vehicle, which at least partially overcomes the disadvantages mentioned above.
  • an intelligent device that is at least partially tailored to an occupant is to be created.
  • a device for displaying a message for an occupant of a motor vehicle having: an input interface for receiving data with information about the message for the occupant; an analysis unit for analyzing the data and generating a control command, the control command causing the information to be output visually in the form of an information symbol by means of an augmented reality display device; and an output interface for transmitting the control command to an augmented reality display device; wherein the control command causes a predefined optical output of the indication at a predefined position in the occupant's field of vision.
  • a system for displaying information for an occupant of a motor vehicle having: a unit for determining information which is to be transmitted to the occupant by means of the information symbol; a device as previously defined; and an augmented reality display device for outputting an indication according to the predefined visual output at a predefined position in the occupant's field of vision in response to a control command of the device.
  • Control command causes the information to be output visually in the form of an information symbol by means of an augmented reality display device; and transmitting the control command to an augmented reality display device; where the Control command causes a predefined optical output of the note at a predefined position in the occupant's field of vision.
  • a technically simple and cost-effective device By using an input interface for receiving data with information about the information for the occupant, a technically simple and cost-effective device can be created which, in particular, does not have to be designed to record the information itself.
  • the device can thus be integrated into existing navigation or infotainment systems.
  • a control command for an augmented reality display device enables improved visualization of the information for an occupant.
  • a driver can direct his gaze to the roadway and does not have to look at an additional display in the motor vehicle.
  • Road safety is increased.
  • Components already installed in the motor vehicle can be used for the display by means of an output interface. It is also conceivable to retrofit a display device and/or to use several display devices in combination.
  • a predefined optical output of an information symbol at a predefined position in the occupant's field of vision By means of a predefined optical output of an information symbol at a predefined position in the occupant's field of vision, the occupant can grasp the information without having to adjust his field of vision. Furthermore, it is also conceivable to direct the occupant's gaze or field of vision to a predefined position by outputting the information and thus to draw the occupant's attention to a dangerous situation, for example.
  • the visibility of the notice can be increased by means of a predefined optical output, for example a suitable color or a suitable contrast can be selected for the notice based on the situation in front of the motor vehicle, for example black writing can be selected if the predefined position is in front of a white one truck is located.
  • the system can also be used for entertainment, for example games such as - I see something that you don't see -, - Tetris - and/or - Pong - can be implemented through flexible context-related design.
  • games such as - I see something that you don't see -, - Tetris - and/or - Pong - can be implemented through flexible context-related design.
  • the predefined position and the predefined optical output are determined by parameters of the game.
  • the device is designed for installation in a motor vehicle and is preferably part of an on-board computer and/or navigation system is. This can significantly increase comfort when driving a car.
  • the device can also be offered as a type of retrofit solution for cars that have already been purchased and can be set up, for example, by replacing or reprogramming the on-board electronics.
  • the input interface is designed to receive sensor data from a sensor with information relating to the occupant's field of vision, the analysis unit being designed to determine the predefined position in the occupant's field of vision based on the sensor data. This can significantly improve the visibility of the notice.
  • the information can be grasped by the occupant without a significant change in the line of sight.
  • the input interface is designed to receive sensor data from a sensor which has at least one steering angle sensor, a speed sensor, a position sensor, a head tracking sensor, an interior camera, in particular an occupant camera, and/or an exterior camera includes, preferably data from at least two sensors, in particular a position sensor and an outdoor camera, can be combined in a sensor fusion. This allows an improved determination of the predefined position.
  • the analysis unit is designed to determine a source of danger in the field of vision of the occupant, in particular the driver, with the control command causing the information symbol to be shifted to the source of danger in the field of vision of the occupant.
  • road safety can be improved.
  • the occupant's attention can be drawn to the source of danger at an early stage. Convenience is increased because preferably no warning tone or other warning signal needs to be emitted to warn the occupant.
  • the analysis unit is designed to generate a predefined optical output, in particular a color and/or a type of information symbol, based on a situation in front of the motor vehicle in the occupant's field of vision and the predefined position in the occupant's field of vision to determine in order to cause an output of the notification symbol with increased visibility for the occupant by means of the control command.

Abstract

L'invention se rapporte à un dispositif (10) pour afficher des informations (24) pour un occupant (30) d'un véhicule motorisé (28) et à un système (18), à un procédé et à un programme informatique correspondants. L'invention divulguée peut en particulier être utilisée pour réaliser l'action suivante : la position d'affichage d'un afficheur tête haute peut être variée de manière souple en fonction du contexte. Dans ce but, un déplacement de la position X et/ou Y et une sélection de couleur adaptée à l'arrière-plan peuvent tous deux être mis en œuvre et être effectués automatiquement. Des informations provenant d'un angle de direction, d'une vitesse, de données cartographiques et également d'un suivi de tête par la caméra intérieure (34) peuvent être combinées pour déterminer la position X et/ou Y. Afin d'obtenir une visibilité optimale pour tout cas de charge, une fusion de capteurs à partir des données de position (32) et d'une caméra extérieure (36) peut en particulier avoir lieu : un contenu ou des informations (24) peuvent ainsi être affichés en fonction de la position d'affichage actuelle, de manière à être plus visibles. Si seulement certaines des informations (24) ou une partie du symbole d'informations (42, 44) se trouvent sur un arrière-plan, seule une partie de la couleur peut également changer, de telle sorte qu'une visibilité est assurée pour le symbole d'informations (42, 44) entier. De plus, l'utilisation de couleurs d'avertissement visuel et le déplacement simultané de l'affichage en direction d'une source d'un danger (46) permettent d'orienter le regard du conducteur (30) vers la situation dangereuse.
