Autonomous Vehicle Driving Condition Component Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autonomous vehicles do not effectively manage driving condition components like windshield wipers and window defrosters to improve visibility during transitions from autonomous to manual mode, leading to potential safety issues and inefficient power consumption.
Innovation Solution
A system that predicts when a driver will switch to manual mode based on current conditions and occupancy, using sensors to determine environmental and cabin conditions, and proactively controls driving condition components like windshield wipers and window defrosters to mitigate these conditions before manual operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If driving condition components are enabled in autonomous mode, then passenger comfort is improved, but power consumption increases
Solution Approach 1:
The system performs preliminary action by predicting when the driver will switch to manual mode and proactively enabling driving condition components before the switch occurs. This ensures visibility conditions are already optimized when manual operation begins, avoiding the need for reactive adjustments that would consume additional power.
Solution Approach 2:
The autonomous vehicle system automatically monitors conditions and manages driving condition components without requiring manual intervention. The system serves itself by detecting environmental conditions, predicting driver intent, and autonomously controlling components like windshield wipers and defrosters based on predicted manual mode transitions.
2Use of energy by moving object
If driving condition components are limited to passenger comfort only, then power consumption is reduced, but driver visibility and safety are compromised during manual mode transitions
Solution Approach 1:
The system enables driving condition components in advance based on predicted manual mode transitions, ensuring driver visibility is optimized before the driver takes control. This preliminary action prevents safety compromises by ensuring conditions are already favorable when manual operation begins.
Solution Approach 2:
The system continuously monitors environmental conditions, vehicle state, and driver behavior patterns to predict when manual mode will be activated. This feedback loop allows the system to adjust driving condition component operation dynamically, balancing power consumption with visibility requirements based on real-time conditions.
3Reliability
If the system proactively controls driving condition components before manual mode, then driver visibility is improved, but system complexity increases
Solution Approach 1:
The system integrates multiple functions into a unified control architecture that handles both autonomous and manual mode operations. The same prediction and control system manages driving condition components across different operating modes, reducing overall system complexity despite the advanced predictive capabilities.

AI summary
A method for controlling a driving condition component of a vehicle includes disabling automatic operation of the driving condition component based on enabling an autonomous operating mode of the vehicle. The method also includes determining, while the vehicle is operating in the autonomous mode, a current condition satisfies an unsafe driving condition for a manual operating mode of the vehicle. The method further includes enabling the driving condition component to mitigate based on predicting a human occupant will enable the manual operating mode during a time period associated with the current condition, the driving condition component being enabled prior to the human occupant switching from the autonomous operating mode to the manual operating mode.
