Autonomous Vehicle Dispatch with Multi-Candidate Route Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autonomous driving vehicle dispatch systems face challenges in ensuring reliable vehicle arrival and customer attraction due to changes in traffic situations, leading to potential delays or impossibility of dispatch, especially when only one vehicle is dispatched without a clear purpose.
Innovation Solution
A vehicle dispatch system that selects multiple candidate vehicles based on their positions and routes to a predetermined dispatch point, using a route search unit to optimize routes and a vehicle dispatch control unit to dispatch at least two vehicles, while managing remote assistance requests to ensure efficient and reliable service.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If only one vehicle is dispatched to the point of dispatch, then the device complexity is reduced, but the reliability of vehicle arrival deteriorates due to traffic situation changes
Solution Approach 1:
The system performs preliminary actions by selecting multiple candidate vehicles in advance before the actual dispatch is needed. The dispatched candidate vehicle selection unit identifies and prepares multiple vehicles as candidates, so when traffic situations change, there are already selected vehicles ready to be dispatched, ensuring reliable arrival without needing to complexly manage real-time single vehicle selection.
2Reliability
If multiple vehicles are dispatched to the point of dispatch, then the reliability of vehicle arrival is improved, but the device complexity increases
Solution Approach 1:
The system applies partial action by selecting multiple dispatched candidate vehicles, but not all available vehicles are dispatched. The route search unit and vehicle selection process identifies a sufficient number of candidate vehicles (more than one) to ensure reliability, while the actual dispatch only activates the necessary subset, avoiding the complexity of managing all possible vehicles.
3Productivity
If multiple vehicles are dispatched, then customer attraction is improved, but the loss of time for vehicle management increases
Solution Approach 1:
The system implements self-service through automated selection and dispatch processes. The dispatched candidate vehicle selection unit, route search unit, and vehicle dispatch control unit work autonomously to select multiple candidate vehicles, determine their routes, and manage their dispatch without requiring manual intervention for each vehicle, thus reducing the time loss for vehicle management while maintaining the ability to attract customers through multiple vehicle availability.

AI summary
A vehicle dispatch system includes an dispatched candidate vehicle selection unit configured to select a plurality of dispatched candidate vehicles for the point of dispatch from the plurality of autonomous driving vehicles based on the point of dispatch and the positions of autonomous driving vehicles, a route search unit configured to search routes to the point of dispatch for the dispatched candidate vehicles based on the point of dispatch, the positions of dispatched candidate vehicles and the map information, a vehicle dispatch control unit configured to dispatch at least two or more of the dispatched candidate vehicles to the point of dispatch, when the dispatched candidate vehicles is selected.
