Vehicle Control Device Dynamic Conversion Rule Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle information monitoring systems require extensive labor and resources to update conversion rule tables for different vehicle types, as each type has unique conversion rules, making it cumbersome to design a device that can monitor information across multiple vehicle types.
Innovation Solution
A vehicle control device and monitoring system that includes a communication unit for transmitting response data and conversion rules, allowing external devices to request and receive necessary conversion rules and vehicle information, eliminating the need for pre-stored conversion rule tables in monitoring devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conversion rule table is included in the vehicle information monitoring device to support multiple vehicle types, then the device can monitor information across different vehicle types, but the device complexity and maintenance labor increase significantly
Solution Approach 1:
The patent extracts the conversion rule table from the vehicle information monitoring device and relocates it to the vehicle control device. This allows the monitoring device to obtain conversion rules dynamically through communication requests, eliminating the need for pre-storing extensive conversion rule tables and significantly reducing device complexity while maintaining multi-vehicle-type compatibility
Solution Approach 2:
The vehicle control device acts as an intermediary that stores and manages conversion rule tables, and provides these rules to external monitoring devices upon request. This intermediary approach allows the monitoring device to access needed conversion rules without having to maintain its own comprehensive conversion rule database
2Adaptability or versatility
If conversion rule tables are updated for new vehicle types, then the monitoring device can support new vehicle types, but the labor and time required for updates increase
Solution Approach 1:
The vehicle control device performs preliminary action by pre-storing conversion rule tables for multiple vehicle types internally. When a monitoring device needs to support a new vehicle type, the conversion rules are already prepared and available in the vehicle control device's memory, allowing rapid deployment without extensive update preparation time
Solution Approach 2:
The system implements a feedback mechanism where the monitoring device can request conversion rules from the vehicle control device, and the vehicle control device responds by providing the appropriate conversion rules. This on-demand feedback approach eliminates the need for manual update preparation and allows rapid adaptation to new vehicle types

AI summary
A vehicle control device includes a communication unit (22) for communication with an external communication target (5), a response data transmission control unit (231) that, in response to a request code to request vehicle information being received by the communication unit (22), transmits response data including vehicle information corresponding to the request code from the communication unit (22), and a conversion rule transmission control unit (232) that, in response to a conversion rule request requesting a conversion rule to convert vehicle information being received by the communication unit (22), transmits a conversion rule corresponding to the conversion rule request from the communication unit (22). The aim is to adapt display functions, such that one monitoring device can be used for a plurality of vehicles.
