Onboard ECU Priority Sharing for Conflicting Vehicle Controls
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle control systems face difficulties in efficiently determining priority for conflicting controls targeting onboard apparatuses, leading to potential delays and inefficiencies.
Innovation Solution
An onboard ECU is introduced that communicatively connects to multiple onboard apparatuses and a vehicle control apparatus, splitting and sharing priority determination processing between the onboard ECU and the vehicle control apparatus, with the onboard ECU prioritizing its own priority determination to minimize delays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single functional unit determines priority for conflicting controls, then the control system structure is simple, but the priority determination becomes difficult and inefficient when controls conflict
Solution Approach 1:
The priority determination function is segmented between the vehicle control apparatus and the onboard ECU. The vehicle control apparatus handles overall coordination while the onboard ECU specifically handles priority determination for controls targeting its connected onboard apparatuses. This segmentation allows efficient conflict resolution without requiring complete centralization, resolving the contradiction between structural simplicity and determination efficiency.
2Ease of operation
If priority determination is centralized in a single unit, then system coordination is simplified, but determining priority for conflicting controls becomes difficult
Solution Approach 1:
The onboard ECU performs priority determination specifically for controls targeting onboard apparatuses it is directly connected to, while the vehicle control apparatus handles overall system coordination. This local specialization allows each unit to excel at its specific function, improving both coordination ease and conflict resolution reliability simultaneously.
3Productivity
If the onboard ECU determines priority for conflicting controls, then priority determination efficiency improves, but the control system complexity increases
Solution Approach 1:
The priority determination function is merged into the onboard ECU that is already present in the system for other control functions. By combining the priority determination capability with the existing onboard ECU rather than adding a completely separate dedicated unit, the system gains efficient conflict resolution without proportionally increasing overall system complexity.

AI summary
Provided is an onboard ECU communicatively connected to a plurality of onboard apparatuses installed in a vehicle and a vehicle control apparatus that performs priority determination relating to control of the onboard apparatuses that includes a control unit that executes processing relating to the control of the onboard apparatuses, wherein in a case where there is conflict in control targeting one onboard apparatus from among the plurality of onboard apparatuses or an associated onboard apparatus group, the control unit executes priority determination for the control; and an onboard apparatus which is a target for priority determination by the control unit and an onboard apparatus which is a target for priority determination by the vehicle control apparatus overlap at least at a portion.
