Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Service providers other than OEMs lack a thorough understanding of vehicle control systems, making it difficult to accurately assess and improve application software due to insufficient information on vehicle equipment and operational states.
Innovation Solution
A vehicle control device and method that includes an equipment management unit to convert standardized commands into vehicle-specific formats, perform equipment control, and determine feasibility, providing nonconformity reasons and suggestions for improvement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If standardized command format is used for application software, then adaptability and ease of operation improve, but manufacturing precision and reliability deteriorate due to lack of vehicle-specific optimization
Solution Approach 1:
The patent introduces a command conversion unit as an intermediary component that translates standardized commands from application software into vehicle-specific control commands. This mediator layer enables third-party applications to interact with vehicle equipment using a universal standardized format, while the conversion unit ensures precise translation to vehicle-specific protocols, thereby maintaining both adaptability and control precision without direct coupling between applications and vehicle hardware
2Measurement precision
If detailed vehicle equipment information is provided to third-party service providers, then application quality improves, but information security and system complexity worsen
Solution Approach 1:
The patent implements a self-service mechanism where the vehicle control device automatically evaluates application commands against vehicle equipment specifications and operational states. Instead of requiring third-party providers to manually assess compatibility, the system autonomously determines feasibility, generates feedback on nonconformities, and provides guidance for improvement, thereby enabling accurate assessment without exposing detailed internal system information or increasing management complexity
3Ease of operation
If command conversion from standardized format to vehicle-specific format is performed, then ease of operation improves, but processing time and system complexity increase
Solution Approach 1:
The patent implements preliminary action by pre-establishing conversion rules and mappings between standardized command formats and vehicle-specific formats. The system prepares translation dictionaries, protocol mappings, and validation criteria in advance, allowing the command conversion unit to perform rapid lookups and transformations during runtime. This pre-preparation significantly reduces real-time processing delays while maintaining comprehensive conversion capabilities

AI summary
A vehicle control device is configured to perform at least one of: executing control of vehicle equipment possessed by the vehicle, and managing a state of the vehicle equipment, receive, from a service providing unit that executes application software, a first command, which is described in a standardized format and requests implementation of a target function utilizing the vehicle equipment, convert the first command into a second command, determine whether the target function can be implemented, cause an equipment management unit to execute an instruction according to the second command, and transmit, together with a nonconformity reason indicating a reason for infeasibility, suggestion information indicating requirement necessary for the target function to be determined feasible, to a requester of the first command.
