Vehicle Visual Indicators for Pedestrian Movement Awareness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ensuring operational safety for semi-automated or autonomous vehicles in areas where pedestrians are present, as existing systems lack effective visualization of vehicle movement states to prevent accidents.
Innovation Solution
A method involving the reception of vehicle operating parameters, determination of indicators for visual display of movement states, and visualization of these indicators using directional light emissions or projections on the surrounding surface to alert pedestrians of potential hazards and safe zones.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If visual indicators are implemented to show vehicle movement states to pedestrians, then operational safety is improved, but device complexity increases
Solution Approach 1:
The patent introduces visual indicators as an intermediary element between the autonomous vehicle and pedestrians. These indicators (such as light beams or projections) serve as a communication medium that conveys vehicle movement state information to pedestrians without requiring direct complex interaction between the vehicle's control systems and pedestrian awareness. The visual indicator acts as a mediator that translates internal vehicle state data into externally comprehensible visual signals.
Solution Approach 2:
The patent replaces traditional mechanical or direct physical communication methods with optical visualization systems. Instead of relying on physical cues or complex mechanical interfaces between vehicle and pedestrian environments, the system uses light-based visual indicators (such as LED projections or laser light beams) to communicate vehicle movement states, thereby substituting mechanical communication pathways with optical fields.
2Loss of information
If multiple operating parameters are visualized to provide comprehensive movement information, then information completeness is improved, but loss of information is reduced
Solution Approach 1:
The patent segments the visualization of operating parameters into distinct visual indicators, each representing specific aspects of vehicle movement state. Rather than attempting to display all parameters simultaneously in a single complex representation, the system divides the information into separate visual elements (such as different light patterns, colors, or projection shapes) that correspond to different operating parameters like velocity, acceleration, direction, and braking status. This segmentation allows comprehensive information transmission while maintaining visual clarity.
Solution Approach 2:
The patent applies different visual characteristics to different indicators based on their specific information content. Each visual indicator is tailored with appropriate local qualities such as specific colors, intensities, patterns, or positions that correspond to particular operating parameters. For example, different colors may represent different movement states, or different light beam directions may indicate different trajectory information, allowing optimized visual communication for each parameter type.

Function Achieved in This Case
Enhances operational safety by providing pedestrians with clear visual cues about vehicle movements, helping them avoid accident zones and understand the vehicle's trajectory, thereby reducing the risk of collisions.
Implementation Method 1
The visualization takes place, for example, using at least one light beam which originates from the vehicle
Implementation Method 2
at least one projection onto the driving surface
