Vehicle Dispatch Selection Using Autonomous Driving Reliability Metrics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle dispatch systems do not allow users to select autonomous driving vehicles, as they lack the capability to determine if a selected vehicle is equipped with autonomous driving functions.
Innovation Solution
A vehicle dispatch system that includes a server and user device capable of communicating to store and display information about autonomous driving functions of registered vehicles, enabling users to select vehicles based on these features, with options including version information, override rate, continuity of autonomous driving, and authentication processes for verifying vehicle and user combinations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the system displays detailed information about autonomous driving functions for each candidate vehicle, then users can make informed selections about autonomous driving vehicles, but the device complexity and information processing load increase
Solution Approach 1:
The system segments information about autonomous driving functions into distinct categories (version information, override rate, continuity, maximum continuation time/distance, average continuation time/distance, cumulative continuation time/distance) and presents them separately for each candidate vehicle. This allows comprehensive information display while maintaining organized, manageable data structures that reduce processing complexity.
Solution Approach 2:
The server pre-calculates and stores multiple metrics about autonomous driving functions (override rate, continuity, maximum/average/cumulative continuation time and distance) before user queries. This preliminary processing of autonomous driving data reduces real-time computation requirements when displaying information to users, thereby reducing system complexity during operation.
2Reliability
If the system provides comprehensive metrics about autonomous driving reliability (version info, override rate, continuity, max/average/cumulative time and distance), then users can determine vehicle reliability, but the loss of time for data processing and transmission increases
Solution Approach 1:
The server pre-calculates comprehensive reliability metrics including version information, override rate, continuity, and maximum/average/cumulative continuation time and distance for each vehicle's autonomous driving function. By performing these calculations in advance and storing them in the database, the system avoids time-consuming real-time computations when users request vehicle information, thus reducing data processing time while maintaining comprehensive reliability assessment.
Solution Approach 2:
The system creates and stores copied versions of autonomous driving performance data in multiple formats (maximum values, average values, cumulative values) in the database. These pre-generated copies allow the system to quickly retrieve and display comprehensive reliability information without recalculating from raw data, significantly reducing data processing time while providing complete reliability metrics.
3Reliability
If the system implements authentication processes for verifying vehicle-user combinations, then dispatch security is enhanced, but the ease of operation decreases due to additional authentication steps
Solution Approach 1:
The server acts as an intermediary that automatically manages authentication between users and vehicles. When a user selects a candidate vehicle, the server verifies the combination of user device and vehicle through backend authentication processes without requiring manual verification steps from the user. This intermediary authentication mechanism enhances dispatch security while maintaining ease of operation by eliminating complex user-side verification procedures.

AI summary
A server includes a unit obtaining a position of a registered vehicle, a unit obtaining a vehicle dispatch position, a unit determining a candidate vehicle based on the vehicle dispatch position and the position of the registered vehicle, a unit transmitting information regarding an autonomous driving function of the candidate vehicle to a user device, a unit receiving information for identifying a dispatch vehicle, and a unit transmitting a vehicle dispatch position to the dispatch vehicle. The user device includes a unit receiving the information regarding the autonomous driving function of the candidate vehicle, a unit displaying the information regarding the autonomous driving function of the candidate vehicle, an unit accepting a user operation for selecting the dispatch vehicle, and a unit transmitting the information for identifying the dispatch vehicle to the server.
