Autonomous Driving Parameter Reset via Single Input
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing autonomous driving systems require multiple operations to reset inter-vehicular distances to their original values, which can be cumbersome and inefficient, especially when system reliability is low.
Innovation Solution
An autonomous driving system with an electronic control unit that allows occupants to easily change parameters relevant to vehicle travel to a regular value using a single input unit, which can function as both the autonomous driving start and canceling operation input, and automatically adjusts parameters based on system reliability and previous settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the inter-vehicular distance is sequentially switched in stages through occupant operation, then the system provides multiple distance options, but it requires multiple operations to restore the original value
Solution Approach 1:
The system stores the original inter-vehicular distance value before any changes are made. When the reset operation is triggered, this pre-stored value is immediately restored without requiring multiple operations. This preliminary action of saving the original state enables instant restoration.
Solution Approach 2:
The invention extracts the reset functionality from the sequential switching mechanism. By separating the restoration function from the parameter changing function, the system can restore the original value independently through a single operation rather than requiring multiple sequential steps.
2Ease of operation
If a separate canceling operation input unit is provided, then the parameter can be easily changed to regular value, but the system configuration becomes more complex
Solution Approach 1:
The autonomous driving start operation input unit is designed to serve multiple functions: it can initiate autonomous driving mode and also reset the inter-vehicular distance parameter to its original value. This multi-functionality eliminates the need for a separate canceling operation input unit, simplifying the system configuration while maintaining ease of operation.
3Stability of the object's composition
If the parameter is changed to regular value during autonomous driving control, then the system can prevent rapid state changes, but it may not respond appropriately when system reliability is low
Solution Approach 1:
The electronic control unit continuously monitors system reliability before executing the parameter reset operation. When the reset operation is detected, the system checks the current reliability level and only proceeds with changing the parameter to the regular value if reliability is sufficient. This feedback mechanism ensures stable operation while maintaining appropriate response to reliability conditions.
