Driving Support Function Prioritization to Skip Condition Checks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing diversification of driving support functions in vehicles leads to a significant load on in-vehicle devices, causing resource wastage and repeated determinations when operating conditions for multiple functions are established simultaneously, or not established at all.
Innovation Solution
An information processing apparatus with a control unit that sequentially determines operating conditions for driving support functions in a predetermined order, skipping determinations for unprocessed functions when conditions are met for any one function, prioritizing based on probability and sensor variability to allocate resources efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the system determines operating conditions for all driving support functions sequentially, then comprehensive function availability is ensured, but processing time and resource consumption increase significantly
Solution Approach 1:
The system implements a skipping mechanism that terminates the sequential determination process immediately when a driving support function's operating conditions are satisfied. This prevents unnecessary processing of subsequent functions, significantly reducing processing time while maintaining reliable determination of available functions. The control unit skips unprocessed functions once one function's conditions are met, directly addressing the time-resource tradeoff.
2Speed
If the system processes multiple driving support functions simultaneously, then response speed improves, but resource consumption and computational load increase
Solution Approach 1:
The system employs periodic action by processing driving support functions in a predetermined sequential order rather than simultaneously. This approach maintains acceptable response speed through efficient sequencing while significantly reducing resource consumption compared to parallel processing. The control unit systematically evaluates functions one by one, consuming resources only when necessary based on condition satisfaction.
3Measurement precision
If the system determines operating conditions for all functions regardless of priority, then complete accuracy is achieved, but unnecessary processing occurs when high-priority functions are satisfied
Solution Approach 1:
The system applies the skipping principle by terminating the determination process immediately when a driving support function's operating conditions are satisfied. This eliminates unnecessary processing of lower-priority functions while maintaining complete accuracy for the satisfied function. The control unit precisely determines condition satisfaction and skips subsequent processing, avoiding energy waste on redundant evaluations.
Solution Approach 2:
The system implements local quality by applying different processing intensities to different functions based on their priority and condition satisfaction status. When a function's conditions are met, the system focuses resources on that specific function and reduces processing for others. This localized approach maintains precision where needed while minimizing unnecessary processing elsewhere.

AI summary
An information processing apparatus (100) comprises a control unit (101) configured to execute: sequentially performing, in a predetermined order, processing of determining whether or not operating conditions for each driving support function are satisfied with respect to each of a plurality of driving support functions included in a first vehicle; and skipping the determinations for unprocessed driving support functions when there is a driving support function for which the operating conditions are determined to be satisfied.
