Abstract

A method for reproducing a map display depending on a driving situation, a device for reproducing a map display depending on a driving situation, and a transportation vehicle having a corresponding device. The method includes detecting one or more driving situation-dependent parameters, wherein at least one driving situation-dependent parameter is based on the geographical position; setting one or more display properties of the map display depending on the one or more detected driving situation-dependent parameters; and reproducing the set map display using a display device. This allows a map display adequate for a situation to be provided to a transportation vehicle operator, the map display clearly and intelligibly reproducing the information relevant to the present driving situation.

First claim

The invention claimed is:

1. A method for adapting a map representation on a transportation vehicle user interface depending on a presently sensed transportation vehicle driving situation, the method comprising:
capturing one or more driving-situation-dependent parameters;
setting one or more representation properties of the map representation based on the one or more captured driving-situation-dependent parameters to generate an adapted map representation, at least one of the one or more driving-situation-dependent parameter being dependent on a geographical position of the transportation vehicle, wherein the setting of the one or more representation properties of the map representation based on the one or more captured driving-situation-dependent parameters includes:
setting a representation scale based on the one or more captured driving-situation-dependent parameters by selecting a representation scale by retrieving one or more representation scale models, wherein each representation scale model defines a dependency of the respective representation scale on one or more captured driving-situation-dependent parameters, and selecting a representation scale based on the one or more retrieved scale models, and
setting a representation perspective based on the one or more captured driving-situation-dependent parameters by retrieving one or more inclination models, each inclination model defining the dependency of the respective representation perspective on one or more captured driving-situation-dependent parameters, and selecting a representation perspective based on the one or more retrieved inclination models; and

automatically reproducing the adapted map representation on a display unit of the transportation vehicle user interface in response to the generation of the adapted map representation,
wherein the one or more representation scale models and the one or more inclination models are multidimensional functions of at least three dimensions whereby both the representation scale and the representation perspective are each influenced by multiple driving-situation-dependent parameters including at least distance of the transportation vehicle from a manoeuver area and transportation vehicle speed.

2. The method of claim 1 , wherein the capturing of one or more driving-situation-dependent parameters comprises at least one of:
selecting a journey route in response to user instruction received via the transportation vehicle user interface;
capturing a maneuver area where a driving maneuver required to follow the selected journey route needs to be carried out;
capturing a distance of the transportation vehicle from the captured maneuver area.

3. The method of claim 1 , wherein the capturing of one or more driving-situation-dependent parameters comprises at least one of:
capturing data identifying a street furniture installation;
rating the captured street furniture installation data in terms of its relevance to the transportation vehicle; and
capturing a distance of the transportation vehicle from the captured street furniture installation.

4. The method of claim 1 , wherein the capturing of one or more driving-situation-dependent parameters comprises at least one of:
capturing a current speed of the transportation vehicle;
capturing a current acceleration of the transportation vehicle;
capturing a currently set steering angle of the transportation vehicle; and
capturing a brightness value inside and/or outside the transportation vehicle.

5. The method of claim 1 , wherein the capturing of the one or more driving-situation-dependent parameters comprises capturing a distance of the transportation vehicle from a predefined position.

6. The method of claim 1 , wherein the setting of one or more representation properties of the map representation based on the one or more captured driving-situation-dependent parameters comprises:
manipulating the map representation based on the one or more captured driving-situation-dependent parameters.

7. The method of claim 1 , wherein the one or more representation scale models and/or the one or more inclination models are each a characteristic curve or a family of characteristic curves.

8. The method of claim 1 , wherein the one or more representation scale models and/or the one or more inclination models follow a linear function, a quadratic function, a polynomial function, a root function, a logarithmic function, a trigonometric function and/or an exponential function at least in sections.

9. The method of claim 1 , wherein the selecting of a representation scale based on the one or more retrieved representation scale models and/or the selecting of a representation perspective based on the one or more retrieved inclination models comprises at least one of:
allocating priority values to the one or more driving-situation-dependent parameters;
selecting a representation scale based on the scale model that defines the dependency of the representation scale on the driving-situation-dependent parameter to which the highest priority has been allocated; and
selecting a representation perspective based on the inclination model that defines the dependency of the representation perspective on the driving-situation-dependent parameter to which the highest priority has been allocated.

10. The method of claim 6 , wherein the manipulating of the map representation based on the one or more captured driving-situation-dependent parameters comprises at least one of:
integrating one or more objects into the map representation based on the one or more captured driving-situation-dependent parameters; and
changing the representation of the one or more integrated objects based on the one or more captured driving-situation-dependent parameters.

11. An apparatus for adapting a map representation by a user interface of a transportation vehicle depending on a presently sensed transportation vehicle driving situation, the apparatus comprising:
a data processing unit;
a capture device for capturing one or more driving-situation-dependent parameters, at least one driving-situation-dependent parameter being dependent on the geographical position of the transportation vehicle; and
a user interface including a display unit for displaying the adapted map representation;
wherein the apparatus carries out a method comprising:
capturing one or more driving-situation-dependent parameters;
setting one or more representation properties of the map representation based on the one or more captured driving-situation-dependent parameters to generate an adapted map representation, at least one of the one or more driving-situation-dependent parameter being dependent on a geographical position of the transportation vehicle, wherein the setting of the one or more representation properties of the map representation based on the one or more captured driving-situation-dependent parameters includes:
setting a representation scale based on the one or more captured driving-situation-dependent parameters by selecting a representation scale by retrieving one or more representation scale models, wherein each representation scale model defines a dependency of the respective representation scale on one or more captured driving-situation-dependent parameters, and selecting a representation scale based on the one or more retrieved scale models, and
setting a representation perspective based on the one or more captured driving-situation-dependent parameters by retrieving one or more inclination models, each inclination model defining the dependency of the respective representation perspective on one or more captured driving-situation-dependent parameters, and selecting a representation perspective
