Lane Following Assist Warning Control for Driver Desensitization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drivers become desensitized to lane-keeping assist mode warnings due to frequent releases for minor reasons and prolonged warnings, leading to potential unawareness of driving risks.
Innovation Solution
Implementing specific conditions for releasing and terminating the lane following assist mode and associated warnings, including traveling environment, lane recognition reliability, and driver interaction, to optimize warning frequency and duration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the lane following assist mode is frequently released for minor reasons and warnings are maintained for a long time, then the driver becomes insensitive to the warning, but the driver may not be aware of a risk
Solution Approach 1:
The patent changes the parameters of warning generation by introducing specific release conditions (lane non-recognition, lane recognition reliability degradation, failure to follow preceding vehicle, dissatisfaction with lane conditions, activation of automatic braking system, failure of steering system) and termination conditions (predetermined time elapsed, driver grabs steering wheel again, vehicle stops, re-entry condition satisfied). This selective parameter change ensures warnings are generated only for significant reasons rather than minor fluctuations, maintaining driver sensitivity while ensuring risk awareness.
Solution Approach 2:
The system implements feedback mechanisms by monitoring multiple parameters (lane recognition status, vehicle speed, steering wheel state, preceding vehicle distance) and adjusting warning behavior based on the combination of these parameters. The feedback loop evaluates whether release conditions are truly significant before generating warnings, and continuously monitors termination conditions to end warnings appropriately, preventing both excessive warnings and missed risks.
2Ease of operation
If warnings are generated frequently for minor reasons, then the driver is notified of potential issues, but the driver becomes insensitive to the warning
Solution Approach 1:
The patent modifies the warning generation parameters by requiring satisfaction of specific release conditions before generating warnings. These conditions include lane non-recognition, lane recognition reliability degradation, failure to follow preceding vehicle, dissatisfaction with lane conditions, activation of automatic braking system, and failure of steering system. By changing the parameter thresholds for warning generation, the system notifies drivers of genuine issues while avoiding notifications for minor reasons that would cause desensitization.
3Reliability
If the warning is maintained for a long time every time it is generated, then the driver is ensured to notice the warning, but the driver becomes insensitive to the warning
Solution Approach 1:
The patent changes the temporal parameter of warning duration by introducing specific termination conditions: a predetermined time elapses after starting the warning, the driver releases the steering wheel and then grabs it again, the vehicle stops traveling and stops, or a re-entry condition of the lane following assist mode is satisfied. This parameter change ensures warnings are maintained long enough to be noticed but terminated promptly to prevent desensitization.
4Reliability
If the lane following assist mode is released based on various conditions, then the system ensures safety by responding to critical situations, but the mode is released frequently for minor reasons
Solution Approach 1:
The patent modifies the release conditions parameters by specifying six critical conditions: lane non-recognition, lane recognition reliability degradation, failure to follow preceding vehicle, dissatisfaction with lane conditions, activation of automatic braking system, and failure of steering system. By changing these parameters to be specific and significant, the system ensures safety responses to critical situations while avoiding releases for minor reasons, maintaining mode continuity.

AI summary
Disclosed herein a driving assistance control method for a vehicle, the method includes the steps of releasing a lane following assist mode in response to that a predetermined first condition for releasing the lane following assist mode is satisfied while the vehicle is traveling in the lane following assist mode; starting a warning to notify the releasing of the lane following assist mode in response to the lane following assist mode is released; and terminating the warning in response to that a predetermined second condition for terminating the warning is satisfied after the warning is started.
