Driver Assistance Failure Response With Risk-Based Route Guidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing driver assistance systems fail to provide timely warnings and assistance when their functions fail, leading to increased risk of accidents due to delayed response to dangerous situations.
Innovation Solution
A method and system that detects driver assistance function failures, generates multiple driving route candidates, assesses driving risks, determines appropriate driver responses, and provides visual, audible, or haptic warnings and assistive steering controls to minimize risk.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If warning is issued only when dangerous situation occurs after driver takes over authority, then system complexity is reduced, but response time to dangerous situation is delayed
Solution Approach 1:
The system performs preliminary risk assessment by generating multiple driving route candidates and evaluating their risks immediately when driver assistance function fails, before the driver takes over. This allows the system to prepare warnings and assistance actions in advance, reducing response time when dangerous situations occur.
2Device complexity
If only simple visual or audible warning is provided, then device complexity is reduced, but driver's ability to immediately recognize avoidance direction is insufficient
Solution Approach 1:
The warning system is segmented into multiple channels: visual warnings display the direction of risk and avoidance direction, audible warnings provide auditory alerts, and assist control provides physical steering assistance. This segmentation ensures that comprehensive information is provided through multiple senses, enabling the driver to immediately recognize the avoidance direction.
3Reliability
If multiple driving route candidates are generated and risk assessment is performed, then driving risk is minimized, but device complexity increases
Solution Approach 1:
The system generates multiple driving route candidates (excessive action) but only implements the one with the minimum risk after evaluation. This partial implementation approach ensures driving safety by considering multiple options while avoiding the complexity of implementing all possible routes simultaneously.

AI summary
A method for assisting driving on failing the driver assistance function of the vehicle according to an embodiment of the present disclosure comprises: detecting a failure of the driver assistance function; generating a plurality of driving route candidates based on a driving state when the driver assistance function fails; determining a driving risk of the vehicle for each of the plurality of driving route candidates; determining an appropriate response action of a driver for minimizing the driving risk of the vehicle, based on the driving risk for each of the plurality of driving route candidates; determining whether the driver took the appropriate response action; and performing a driving assistance in a direction of minimizing the driving risk of the vehicle if it is determined that the driver did not take the appropriate response action.
