Adaptive Vehicle Function Control for Driver Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for operating motor vehicles do not effectively adapt safety and driving functions to the driver's capabilities, leading to potential endangerment of the driver and others due to self-overestimation or lack of experience.
Innovation Solution
A method and system that enable motor vehicle functions based on stored data related to the identified driver, gradually introducing and modifying driving functions according to the driver's experience and capability, including monitoring and adjusting features like maximum speed, lane changes, and no-hands driving, to ensure safe operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If all driving functions are enabled for the driver, then the ease of operation is improved, but the safety deteriorates due to driver self-overestimation or lack of experience
Solution Approach 1:
The system dynamically changes the parameter of function availability based on the driver's proven competence level. Initially, only basic functions are enabled, and additional functions are progressively unlocked as the driver demonstrates safe operation, thereby adapting the system to the driver's actual capability rather than assuming full competence
Solution Approach 2:
The system implements continuous feedback by monitoring the driver's operation quality and using this information to adjust function availability. The control device evaluates driving behavior and automatically enables or disables functions based on the driver's demonstrated skill level, creating a closed-loop safety mechanism
2Reliability
If driving functions are restricted for inexperienced drivers, then the safety is improved, but the ease of operation deteriorates
Solution Approach 1:
The system transitions from a static function availability model to a dynamic one where function access changes over time based on driver performance. The same driver receives different function sets at different times, with the system automatically adapting the operational envelope as the driver gains experience and proves competence
Solution Approach 2:
The system performs preliminary assessment and training before full function activation. New drivers undergo a controlled introduction period where functions are gradually enabled based on demonstrated competence, preparing them safely for full system capabilities without sudden exposure to all functions
3Reliability
If the system monitors and adapts functions based on driver capability, then the safety is improved, but the device complexity increases
Solution Approach 1:
The control device integrates multiple functions including driver monitoring, capability assessment, and dynamic function management into a single unified system. This multi-functional approach consolidates what could be separate complex systems into one integrated control unit that handles identification, monitoring, and adaptive function enablement
