Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic control apparatuses for vehicles lack the ability to accurately store vehicle state data at appropriate times, leading to inadequate data retrieval for analysis due to manual operation of trigger generation devices.

An electronic control apparatus with a vehicle state storing part, trigger setting part, and data type setting part that allows for external designation of triggers and data types, enabling precise storage of vehicle state data in response to predetermined conditions, ensuring accurate data retrieval for analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If vehicle state data is stored only when abnormality is detected or manual trigger is operated, then storage resources are conserved, but the timing of data storage becomes inappropriate and accurate analysis data cannot be retrieved
Solution Approach 1:
The electronic control apparatus automatically generates trigger signals based on predetermined conditions (abnormality detection, time intervals, mileage) without requiring manual intervention. The system serves itself by monitoring its own operational parameters and autonomously deciding when to store vehicle state data, eliminating the need for manual trigger generation while ensuring data is captured at appropriate moments
Solution Approach 2:
The system continuously monitors vehicle operational parameters and uses this feedback to determine when to generate trigger signals for data storage. By establishing a closed-loop monitoring system that detects abnormalities and automatically triggers storage events, the apparatus ensures data is captured at meaningful moments without manual intervention, resolving the contradiction between automated timing and manual operation requirements
2Adaptability or versatility
If fixed trigger conditions are used for data storage, then storage timing is simplified, but adaptability to different analysis requirements is reduced
Solution Approach 1:
The apparatus allows predetermined configuration of trigger conditions and data types before actual operation. Multiple trigger patterns (abnormality-based, time-based, mileage-based) and data type combinations can be pre-set in the control program, enabling the system to adapt to different analysis requirements without complex runtime configuration. This preliminary setup reduces operational complexity while maintaining high adaptability
Solution Approach 2:
The system dynamically selects which trigger pattern and data type combination to use based on current operational needs. The electronic control apparatus can switch between different predetermined configurations (e.g., from abnormality-triggered storage to time-interval storage) depending on the analysis requirements, providing flexibility without requiring complex real-time decision-making logic

AI summary
An electronic control apparatus includes a vehicle state storing processing part, which stores a vehicle state data when a predetermined trigger is generated, and a trigger setting processing part, which sets the trigger in correspondence to a designation from an external side. The electronic control apparatus further includes a data type setting part for setting, based on the designation from the external side, a stored vehicle state data type. The vehicle data storing part stores the vehicle state data in different addresses. The trigger setting part sets the trigger based on the address designated from the external side and a data length of the vehicle state data stored in the address. The data type setting part sets the stored vehicle state data type based on the address designated from the external side and the data length of the vehicle state data stored in the address.
