Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle guidance systems provide limited visual information to drivers during maneuvers like parking, leading to reduced efficiency and safety.
Innovation Solution
A visual guidance system that uses sensors to detect the vehicle environment, dynamically displays a visual representation of the environment, and overlays proposed vehicle trajectories, providing intuitive guidance for safer and more efficient maneuvers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If current guidance systems use auditory warnings or static sketches with color-coded warnings, then the system complexity is reduced, but the information completeness and driver awareness are insufficient
Solution Approach 1:
The patent transitions from traditional auditory warnings and static 2D sketches to a dynamic bird's-eye view display that presents spatial information in a new dimensional format. This overhead visualization dimension allows complete trajectory and environment information to be displayed simultaneously, resolving the contradiction between information completeness and system complexity by organizing data spatially rather than through multiple separate warnings.
Solution Approach 2:
The system calculates and displays the complete proposed trajectory in advance before the maneuver begins. By showing the entire path ahead of time, the driver can understand the full maneuver sequence beforehand, reducing information loss during execution without requiring complex real-time adjustments or additional warning systems.
2Reliability
If the system displays complete trajectory and environment information, then driver awareness and safety are improved, but the ease of operation and driver attention management may be compromised
Solution Approach 1:
The bird's-eye view display differentiates information by importance and spatial location, with the trajectory path, environment obstacles, and vehicle position each rendered with distinct visual characteristics. This local differentiation allows the driver to quickly grasp critical safety information without being overwhelmed by uniform detailed data everywhere, maintaining ease of operation while improving safety awareness.
3Loss of information
If auditory warnings are used for distance alerts, then the system complexity is low, but the information richness and spatial awareness provided to the driver is limited
Solution Approach 1:
The patent replaces auditory warning systems with a visual bird's-eye view display that naturally encodes spatial distance and position information through graphical representation. Objects closer to the vehicle appear larger and in more critical positions on the display, providing rich spatial information without requiring multiple auditory channels or complex warning hierarchies.
Data Source
AI summary
The disclosure relates to a method and system for providing visual guidance to a driver of a vehicle. The method comprises detecting, by a plurality of sensors of the vehicle, sensor data representing a vehicle environment; dynamically displaying, by a display of the vehicle, a visual representation of the vehicle environment; overlaying the visual representation with one or more first visual elements representing a proposed trajectory of a maneuver of the vehicle within the vehicle environment.
