Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drivers face challenges in optimizing fuel efficiency due to unpredictable traffic conditions and changing traffic light timings, making it difficult to plan routes that minimize fuel usage and stops, as existing systems lack real-time adaptive strategies to adjust vehicle speed and route based on localized obstacles and traffic patterns.
Innovation Solution
A vehicle computing system that processes real-time data from various sources, including other vehicles and infrastructure, to determine and execute strategies that minimize fuel usage by either preserving momentum or employing stopping strategies based on the likelihood of clearing obstacles, thereby optimizing fuel efficiency and reducing unnecessary stops.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a driver maintains higher speed to reduce travel time, then productivity is improved, but fuel consumption increases due to frequent stops and acceleration
Solution Approach 1:
The system performs preliminary actions by receiving advance information about upcoming obstacles and traffic conditions, then proactively adjusts vehicle speed and routing before reaching problematic areas. This allows the vehicle to maintain optimal momentum and avoid frequent stops, thereby reducing fuel consumption while maintaining productivity.
Solution Approach 2:
The system dynamically adjusts vehicle control strategies based on real-time conditions. By continuously receiving updated information about obstacles and traffic patterns, the system adapts speed and routing decisions to minimize fuel consumption while maintaining efficient travel time, resolving the contradiction between productivity and energy use.
2Adaptability or versatility
If a driver follows fixed routing without real-time adjustments, then device complexity is reduced, but adaptability to changing traffic conditions deteriorates
Solution Approach 1:
The system achieves high adaptability through a multi-functional architecture where a single processing unit handles diverse tasks: receiving obstacle information, analyzing traffic patterns, calculating optimal routes, and controlling vehicle operations. This universal approach provides comprehensive adaptability without proportionally increasing system complexity.
Solution Approach 2:
The system uses an intermediary information processing layer that receives data from various sources (obstacle detection, traffic sensors) and translates it into actionable control decisions. This intermediary layer absorbs complexity, allowing the vehicle to adapt to changing conditions while keeping the overall system architecture manageable and organized.
3Use of energy by moving object
If a vehicle uses momentum-preserving strategy to reduce fuel consumption, then energy efficiency is improved, but the ability to respond to unexpected obstacles deteriorates
Solution Approach 1:
The system continuously monitors real-time conditions including obstacle detection and vehicle state, then provides feedback to adjust the momentum-preserving strategy. When obstacles are detected, the system immediately modifies speed and routing decisions, ensuring that fuel efficiency is optimized only when safe, while maintaining reliable response capability to unexpected situations.
Solution Approach 2:
The system dynamically changes operational parameters such as speed, acceleration rate, and routing based on real-time conditions. By adjusting these parameters in response to detected obstacles and traffic patterns, the system maintains both fuel efficiency through momentum preservation and reliability through adaptive response to changing conditions.
Data Source
AI summary
A system includes a processor configured to receive information indicating the presence of an upcoming obstacle along a route and determine a vehicle-control strategy to minimize expected fuel usage between a current location and an obstacle location. The processor may further control the vehicle in accordance with the control strategy or recommend driver actions in accordance with the control strategy.
