Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle control systems may fail to operate critical functions, such as automatic stopping, due to battery failures, which can occur from insufficient power supply or degradation, leading to safety concerns during vehicle travel.
Innovation Solution
A vehicle control device that includes a CPU with a discharge performance determination section to assess the battery's ability to supply the required current for functions like automatic driving, and an execution availability determination section to inhibit or permit function control based on the battery's capability, ensuring safe operation by preventing function execution when the battery cannot discharge the necessary current.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the vehicle system executes predetermined function control without battery discharge verification, then the ease of operation is improved, but the reliability deteriorates due to potential battery failure during critical operations
Solution Approach 1:
The discharge performance determination section performs battery discharge capability verification before the control section executes predetermined function control. This preliminary action ensures that the battery can supply required current for automatic stopping and other critical functions, preventing system failure due to insufficient power supply while maintaining operational simplicity through automated assessment.
2Reliability
If the vehicle system performs discharge testing before function execution, then the reliability is improved, but the loss of time increases due to additional determination steps
Solution Approach 1:
The discharge performance determination section conducts essential battery capability verification with appropriate depth and duration to ensure reliability for critical functions like automatic stopping. The testing is calibrated to perform sufficient verification without excessive duration, balancing reliability improvement with acceptable time loss through optimized determination parameters.
3Object-affected harmful factors
If the control section is inhibited from executing functions when battery discharge capability is insufficient, then the safety is improved, but the productivity deteriorates due to restricted function execution
Solution Approach 1:
The execution availability determination section acts as an intermediary between the discharge performance determination section and the control section. It evaluates battery capability results and makes intelligent decisions about function execution, permitting operations when safe and inhibiting only when necessary. This mediator approach ensures safety by preventing execution during insufficient battery conditions while maintaining productivity by allowing normal operations when battery performance is adequate.
