Vehicle Head-Up Display Using 3D Predictive Environment Modeling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current head-up displays in vehicles do not effectively improve the visualization and perception of predictive information for drivers, leading to potential distractions while driving.
Innovation Solution
A method and device for a head-up display that uses predefined route data and predictive operating variables to create a three-dimensional model of the vehicle's environment, displaying graphic elements in a contact-analogous manner to directly relate virtual information to the real environment, enhancing the driver's understanding of operating strategies and instructions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If predictive information is displayed using conventional head-up display methods, then information is provided to the driver, but the visualization and perception of the information remains ineffective and may cause distraction
Solution Approach 1:
The patent transitions from conventional two-dimensional flat display to a three-dimensional virtual reality environment. Route data and predictive operating variables are rendered as spatial objects positioned in three-dimensional space relative to the vehicle's actual environment, enabling intuitive depth perception and spatial understanding without requiring driver attention shifts
Solution Approach 2:
The system creates a virtual copy of the real-world driving environment by generating a three-dimensional model based on route data and sensor inputs. Predictive information is overlaid as virtual objects within this copied environment, allowing drivers to perceive future states and operating strategies in the context of the actual driving scene without distraction
2Loss of information
If detailed predictive information is provided to the driver, then operating strategies and instructions are communicated, but the complexity of information processing increases
Solution Approach 1:
The patent transforms abstract predictive data into visually intuitive three-dimensional virtual objects with spatial positioning, scaling, and orientation parameters that naturally convey meaning. Operating strategies and instructions are encoded in the spatial relationships and visual properties of virtual objects rather than through complex data structures, simplifying information processing while maintaining detail
Data Source
AI summary
Predefined route data for a driving route situated in front of the vehicle in the driving direction are provided. Further, at least one predefined predictive operating variable for the vehicle is provided. A three-dimensional model for a predefined environment of the vehicle is determined as a function of the route data. A graphic element is determined as a function of the three-dimensional model and of the at least one predictive operating variable. A head-up display of the vehicle has a predefined display field. The graphic element is displayed in the predefined display field. The graphic element is determined and displayed such that the graphic element is perceived by a viewer of the display field from a predefined viewing position with direct reference to the real environment of the vehicle.
