Autonomous Vehicle Rerouting for Real-Time Destination Changes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autonomous vehicles face challenges in adapting to changing environments, such as obstructed or unsafe destinations, which can lead to inefficiencies and user dissatisfaction, as they are unable to dynamically change their destination in real-time while en route.
Innovation Solution
The system allows autonomous vehicles to determine and change their destination from a first location to a second location in real-time using sensor data and a location database of preferred sites, ensuring safer and more accessible service delivery, while also enabling users to request changes to the service location.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the autonomous vehicle follows the original route to the first location, then the vehicle can complete the service request as initially planned, but the vehicle cannot adapt to environmental changes such as obstructed or unsafe destinations
Solution Approach 1:
The system dynamically changes the destination from a static first location to a dynamic second location based on real-time environmental conditions. The computing system continuously monitors environmental data and adjusts the destination accordingly, making the route planning adaptive rather than fixed.
Solution Approach 2:
The system uses environmental sensor data as feedback to determine whether the original destination remains viable. When sensors detect obstructions or unsafe conditions at the first location, this feedback triggers the computing system to calculate and implement an alternative second location, creating a closed-loop control system.
2Reliability
If the autonomous vehicle changes destination in real-time, then the vehicle can provide safer and more accessible service, but additional computing resources and processing are required
Solution Approach 1:
The system performs preliminary calculations of alternative destinations using historical data and location databases before real-time conditions require changes. By pre-processing potential alternative locations and their characteristics, the system reduces the computational burden during critical real-time decision-making moments.
Solution Approach 2:
The system changes parameters such as destination coordinates, route parameters, and service location based on environmental conditions. By adjusting these parameters dynamically rather than recalculating entire route plans, the system reduces computational energy consumption while maintaining safety and accessibility.
3Speed
If the autonomous vehicle uses a location database of preferred sites, then the vehicle can quickly determine alternative destinations, but the system requires access to and processing of database information
Solution Approach 1:
The location database pre-stores preferred sites and alternative destinations with their characteristics and suitability criteria. This preliminary organization of data allows the system to quickly retrieve and evaluate alternative locations without performing complex real-time analysis, significantly speeding up destination determination.
Solution Approach 2:
The system uses simplified representations or copies of location data from the database rather than processing complete geographic information system datasets. By working with condensed location models containing only essential parameters, the system achieves fast processing with reduced computational complexity.
