Vehicle Operation Management System Arrival Time Determination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle operation management systems struggle to accurately identify the arrival and departure times of a vehicle at its destination, as they rely on incomplete information about the vehicle's position and speed.
Innovation Solution
A vehicle operation management system that includes a travel record information acquisition unit, a destination information acquisition unit, and a determination unit. This system acquires travel record information indicating the vehicle's position, passing time, and speed, and destination information indicating the vehicle's destination. The determination unit then accurately determines the arrival and departure times based on this information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If existing vehicle operation management systems use basic position information to determine arrival and departure times, then the system complexity is low, but the measurement precision of arrival and departure times is insufficient
Solution Approach 1:
The patent segments the determination of arrival and departure times into multiple independent analysis dimensions: position information, speed information, and time information. Each dimension is processed separately through dedicated determination units (position determination unit, speed determination unit, time determination unit), and their results are integrated to achieve precise time identification. This segmentation allows complex determination to be broken down into manageable, specialized components.
Solution Approach 2:
The patent transitions from two-dimensional position-based determination to three-dimensional determination by incorporating speed as an additional dimension. The system now analyzes position, speed, and time simultaneously, creating a more robust determination framework. This dimensional expansion enables the system to distinguish between vehicles passing through and vehicles arriving/departing by evaluating speed characteristics alongside position data.
2Reliability
If the system uses only position information to determine vehicle status, then the device complexity is low, but the reliability of vehicle operation management is insufficient
Solution Approach 1:
The patent merges multiple determination mechanisms (position determination, speed determination, time determination) into a unified vehicle operation management system. These determination units work together synergistically, where position information identifies potential arrival/departure events, speed information confirms the actual status change, and time information records the precise moments. This merging of multiple determination approaches enhances reliability by cross-validating results across different data sources.
Solution Approach 2:
The system implements feedback mechanisms where the determination units continuously monitor and adjust their assessments based on incoming data. The position determination unit receives feedback from speed and time determinations to refine arrival/departure time identification. This multi-loop feedback structure ensures that the system can adapt to varying vehicle behaviors and accurately distinguish between different operational states, thereby improving overall reliability.

AI summary
A vehicle operation management system includes: a travel record information acquisition unit that acquires travel record information indicating a position of a vehicle, a time at which the vehicle has passed through the position, and a speed of the vehicle at the time; a destination information acquisition unit that acquires destination information indicating a position of a destination of the vehicle; and a determination unit that determines an arrival time of the vehicle at the destination and a departure time of the vehicle from the destination, based on the travel record information and the destination information.
