Vehicle Interface Coordination for Usage-Based Billing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems lack a method to accurately charge service providers for services rendered to vehicles, as they do not effectively track and calculate usage fees based on vehicle-dependent operations.
Innovation Solution
A service providing system that includes a vehicle control system and a server, where the vehicle control system coordinates between a service-system functional block and a functional block, converting access requests into vehicle-dependent formats and creating access logs, which the server uses to calculate interface usage fees.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a service-system functional block provides services to a vehicle using a vehicle-independent format, then service adaptability and ease of operation are improved, but there is no mechanism to track interface usage for billing purposes
Solution Approach 1:
The patent introduces a coordination control section as an intermediary between the service-system functional block and the functional block. This intermediary captures access requests in vehicle-independent format, converts them to vehicle-dependent format, and creates access logs for billing purposes, thus resolving the contradiction between service adaptability and usage tracking
Solution Approach 2:
The patent creates a copy of the access request information in the form of access logs. The coordination control section generates access logs that duplicate the essential usage information from the original access requests, enabling billing without interfering with the vehicle-independent service interface
2Reliability
If access requests are converted from vehicle-independent format to vehicle-dependent format, then system coordination and reliability are improved, but device complexity increases
Solution Approach 1:
The patent segments the system into distinct functional blocks: a service-system functional block that handles vehicle-independent services, a coordination control section that manages format conversion, and functional blocks that execute vehicle-dependent processes. This segmentation isolates the conversion complexity to a specific component while maintaining overall system reliability
3Measurement precision
If interface usage is tracked through access logs, then billing accuracy and measurement precision are improved, but data processing and storage requirements increase
Solution Approach 1:
The patent extracts only the essential billing-related information from access requests to create access logs. The coordination control section captures specific usage data (interface usage counts and communication data amounts) without storing entire request payloads, thus achieving billing accuracy while minimizing data storage requirements
Data Source
AI summary
A service providing system includes a vehicle control system and a server. The vehicle control system implements coordination between a service-system functional block and a functional block. The functional block converts an access request expressed in a vehicle-independent format and transmitted from the service-system functional block into a vehicle-dependent format. The coordination control section transfers the access request to the functional block, and creates an access log. The server uses the access log to calculate an interface usage fee generated by the service-system functional block using the functional interface.
