Abstract

A graphics display system for driver information and driver assistance applications generates controllable and dynamic graphical effects in conjunction with 3D visualization of maps. The system generates a display of a map in a 3D virtual environment that responds to the environment changes in a dynamic and visually intuitive manner for a vehicle operator. The system processes environment information, including lighting condition, weather condition, and other data acquired from different sensors in the vehicle such as cameras and lighting sensors, or through networked information services. The graphics display can be integrated with different driver information and driver assistance system embodiments including mobile platforms, in-vehicle information systems, web platforms, and PC systems.

Dependent claims

An in-vehicle information system comprising:

a memory configured to store:
map data corresponding to a plurality of objects in a virtual environment corresponding to a physical environment external to a vehicle;
and
rendering parameter data including a plurality of rendering parameters corresponding to graphical effects to modify a visual representation of the plurality of objects in the map data;
and
control parameter data including a plurality of control parameters, each control parameter including an association between a predetermined environmental condition in the physical environment external to the vehicle and at least one rendering parameter in the plurality of rendering parameters;
an environment data collection device configured to receive environment data corresponding to the physical environment external to the vehicle;
a display device configured to generate a graphical depiction of the plurality of objects in the virtual environment;
and
a controller operatively connected to the memory, the environment data collection device, and the display device, the controller being configured to:
receive the environment data corresponding to the physical environment external to the vehicle;
identify a first rendering parameter in the plurality of rendering parameters with reference to the plurality of control parameters and the environment data;
and
generate a visual depiction of the virtual environment including at least one object in the map data and a graphical effect corresponding to the first rendering parameter being applied to the at least one object in the virtual environment.

A method of generating a display of a virtual environment corresponding to a physical environment external to a vehicle comprising:

receiving with a controller environment data corresponding to a physical environment external to the vehicle;
identifying with the controller a first rendering parameter in a plurality of rendering parameters stored in a memory with reference to a plurality of control parameters stored in the memory and the environment data, each rendering parameter in the plurality of rendering parameters corresponding to a graphical effect to modify a visual representation of an object in map data stored in the memory, each control parameter including an association between an environmental condition in the physical environment external to the vehicle and at least one rendering parameter in the plurality of rendering parameters;
and
generating with the controller and a display device a visual depiction of a virtual environment including at least one object in the map data stored in the memory with a graphical effect corresponding to the first rendering parameter being applied to at least one object in the virtual environment with the display device.
