Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current autonomous vehicle technologies do not effectively display surrounding vehicle speed to drivers, leading to potential degradation in understanding, especially for vehicles farther away.
Innovation Solution
An ego-vehicle system that uses processors, sensors, and displays to depict the spatio-temporal behavior of target objects, such as surrounding vehicles, through graphical indicators that show speed, direction, and position, using machine-readable instructions to adjust the patterning based on the object's behavior.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If surrounding vehicle speed is acquired using LiDAR or similar sensors, then the data for path planning is available, but the driver cannot effectively understand or perceive the surrounding vehicle speed, especially for far removed vehicles
Solution Approach 1:
The patent transforms the representation of vehicle speed from a single numerical value to a two-dimensional visual display showing both speed magnitude and direction. The display presents surrounding vehicle speeds as graphical elements with length indicating speed magnitude and orientation indicating direction, allowing drivers to intuitively comprehend spatial velocity information without complex numerical data processing
Solution Approach 2:
The patent employs color coding to represent different speed ranges and directions of surrounding vehicles. By assigning distinct colors to different speed categories and directional quadrants, the system enables drivers to quickly grasp the behavior of multiple surrounding vehicles through color perception alone, reducing the cognitive load required to interpret speed data
2Reliability
If the driver checks surrounding vehicles visually occasionally, then the driver can perceive some information, but the understanding of surrounding vehicle speed is degraded, particularly for far removed vehicles
Solution Approach 1:
The patent replaces the mechanical visual checking process with an automated sensor-based display system. Sensors continuously acquire surrounding vehicle speed data and the display system automatically presents this information to the driver, eliminating the need for manual visual scanning and providing reliable speed information without time loss
Solution Approach 2:
The system implements continuous monitoring and display of surrounding vehicle speeds through automated sensors and real-time graphical presentation. This continuous information flow ensures the driver always has current speed data without needing to periodically interrupt driving to check surroundings, maintaining constant awareness with zero time loss
3Ease of operation
If traditional displays show surrounding vehicle information, then basic data is presented, but the information is not accessible or intuitive for drivers to understand quickly
Solution Approach 1:
The patent enhances traditional speed displays by adding directional information as a second dimension. Instead of showing only speed magnitude, the display presents velocity as vectors with length representing speed and orientation representing direction, enabling drivers to intuitively understand both how fast and where surrounding vehicles are moving simultaneously
Solution Approach 2:
The system uses color coding to encode different speed ranges and directional information, making the display immediately comprehensible. Different colors represent different speed categories and directional quadrants, allowing drivers to grasp the behavior of multiple surrounding vehicles at a glance through rapid color processing rather than detailed numerical analysis
