Driver-Aware Vehicle Warning Control for Excessive Alarm Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle control systems often issue excessive alarms that bother drivers, failing to appropriately balance alarm intensity with driving conditions.
Innovation Solution
A vehicle control device that recognizes the surrounding situation and driving status, including steering conditions and driver line of sight, to adjust alarm intensity and execution conditions based on these factors, preventing excessive alarming.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If alarm execution conditions are set to be sensitive to detect unsafe driving behaviors, then alarm issuance accuracy is improved, but excessive alarming occurs that bothers the driver
Solution Approach 1:
The system dynamically changes alarm execution parameters (thresholds, conditions) based on the driver's operational state. When the driver is in a highly concentrated state (gripping steering wheel, line of sight forward), the alarm execution conditions are made stricter, raising the threshold for alarm issuance. This resolves the contradiction by adapting the sensitivity parameters to the current driving context, maintaining high alarm accuracy while preventing excessive alarming.
Solution Approach 2:
The system continuously monitors driver state (steering wheel grip, line of sight direction) and uses this feedback to adjust alarm execution conditions in real-time. This closed-loop feedback mechanism allows the system to distinguish between intentional and unintentional unsafe behaviors, issuing alarms only when truly necessary, thus improving alarm accuracy while reducing excessive alarming.
2Reliability
If alarm intensity is increased to ensure driver attention, then safety warning effectiveness is improved, but driver disturbance increases
Solution Approach 1:
The system dynamically adjusts alarm intensity parameters based on driver state and situation severity. When the driver is highly concentrated and the situation is minor, alarm intensity is reduced. When the driver is inattentive or the situation is severe, alarm intensity is increased. This resolves the contradiction by making alarm intensity adaptive rather than fixed, ensuring effectiveness while minimizing disturbance.
3Object-affected harmful factors
If alarm execution conditions are made strict to reduce false alarms, then excessive alarming is prevented, but alarm response timeliness deteriorates
Solution Approach 1:
The system dynamically adjusts alarm execution conditions based on real-time driver state rather than using fixed strict thresholds. When driver concentration is high, conditions are stricter to prevent false alarms. When driver attention is low, conditions become more lenient to ensure timely alarm issuance. This dynamic adaptation resolves the contradiction between reducing false alarms and maintaining timely response.

AI summary
A vehicle control device having circuitry configured to: recognize a surrounding situation of a vehicle; recognize a driving status of the vehicle involving a driver; and issue an alarm to the driver via a predetermined alarm device based on the recognized surrounding situation and the recognized driving status. The circuitry is configured to recognize the driving status including a steering condition with respect to the vehicle and a direction of a line of sight of the driver and issue the alarm at a predetermined alarm intensity when a predetermined execution condition is satisfied based on the surrounding situation, and in a case where at least one of the steering condition and the direction of the line of sight satisfies a predetermined condition, the circuitry is configured to make the execution condition stricter and/or decrease the alarm intensity as compared with a case where the predetermined condition is not satisfied.
