Shared Vehicle Dispatch Energy Supply Using Fleet Cruising Distance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In on-demand vehicle dispatch services, the short lead time from request to dispatch can result in insufficient charging time, leading to waiting times for users, affecting both electric and gasoline/diesel vehicles.
Innovation Solution
A vehicle dispatch management system calculates the total cruising distance of shared vehicles and determines the necessity of energy supply, instructing energy replenishment when this distance falls below a predetermined value to maintain service capacity, ensuring vehicles can be dispatched promptly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the vehicle dispatch service operates in on-demand type with short lead time, then the responsiveness to user requests is improved, but the charging time becomes insufficient and user waiting time increases
Solution Approach 1:
The system performs preliminary actions by calculating the total cruising distance of the fleet in advance and determining energy supply necessity before dispatch requests are fulfilled. When the total cruising distance falls below a threshold, the system proactively instructs shared vehicles to proceed to charging stations, ensuring energy replenishment occurs before vehicles are needed for dispatch, thus maintaining service responsiveness without causing user waiting time.
2Reliability
If the remaining battery power is insufficient, then the vehicle cannot be dispatched, but charging takes time that conflicts with short lead time requirements
Solution Approach 1:
The system implements feedback by continuously monitoring the total cruising distance of the shared vehicle fleet and using this information to dynamically adjust energy supply decisions. When the aggregated cruising distance of all shared vehicles falls below a predetermined threshold, the system generates supply instructions to charging stations. This feedback mechanism ensures that charging activities are coordinated at the fleet level rather than individually, maintaining dispatch availability while minimizing the impact of charging time on service delivery.
3Productivity
If individual vehicles are charged when battery is low, then each vehicle can be dispatched, but the overall fleet service capacity may still be insufficient
Solution Approach 1:
The system merges the energy management of individual vehicles into a unified fleet-level assessment by calculating the total cruising distance of all shared vehicles. Instead of making charging decisions based on individual vehicle battery levels alone, the system aggregates this information and makes coordinated energy supply decisions for the entire fleet. This combining approach ensures that the total service capacity of the fleet is maintained at adequate levels, preventing situations where individual vehicles are charged but overall fleet capacity remains insufficient to meet demand.

AI summary
In a vehicle dispatch management system which manages a plurality of shared vehicles (2) and dispatches the shared vehicles in response to a dispatch request from a user, the vehicle dispatch management system includes: an individual cruising distance calculation device (22) configured to calculate a cruising distance of each of the shared vehicles; a total cruising distance calculation device (17) configured to calculate a total cruising distance of all of the shared vehicles; an energy supply determination device (18) configured to determine a necessity of traveling energy supply of the shared vehicle when the total cruising distance is equal to or less than a first predetermined value; and a supply instruction device (19) configured to instruct a supply instruction to the shared vehicle determined to be supplied on the basis of determining the necessity of traveling energy supply of the shared vehicle.
