Vehicle Pothole Detection and Light Display System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicle occupants experience discomfort and vehicle components undergo wear and tear due to driving over road irregularities like potholes, as existing technologies lack effective methods to predict and avoid such obstacles in real-time.
Innovation Solution
A vehicle computer system that determines the position of potholes relative to the predicted vehicle path, actuates a linear arrangement of lights to indicate the pothole and wheel positions, and outputs directional guidance to the human machine interface to avoid the pothole by changing display characteristics such as color or shape, using data from sensors and potentially remote computers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If real-time pothole detection and avoidance system is implemented, then driver comfort and vehicle component protection are improved, but device complexity increases
Solution Approach 1:
The system segments the pothole detection and avoidance function into distinct modules: sensor data acquisition, pothole detection algorithm, vehicle path prediction, and HMI light arrangement control. Each module operates independently but contributes to the overall function, making the complex system more manageable and maintainable while providing reliable pothole avoidance capability
Solution Approach 2:
The system performs preliminary detection of potholes and prediction of vehicle path before the vehicle actually encounters the obstacle. By identifying potholes in advance and calculating the predicted vehicle path beforehand, the system can provide timely warnings to the driver, allowing preventive action to avoid discomfort and damage before they occur
2Reliability
If pothole detection accuracy is improved, then avoidance effectiveness increases, but measurement precision requirements increase
Solution Approach 1:
The system introduces an intermediary computational layer that processes sensor data to detect potholes and predict vehicle path. Rather than requiring direct high-precision measurement of pothole position, the system uses intermediate calculations including vehicle dynamics modeling and path prediction to determine whether the vehicle will encounter the pothole, reducing the direct measurement precision burden while maintaining avoidance effectiveness
Data Source
AI summary
Upon determining a position of a pothole relative to a predicted vehicle path, one or more lights in a linear arrangement of lights are actuated based on the position of the pothole relative to the vehicle path.
