Vehicle Blind-Spot Alert Control With Variable Warning Intensity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle alert systems for blind spots become ineffective as drivers become accustomed to frequent alerts, reducing their effectiveness over time.
Innovation Solution
A vehicle system that includes a position detection circuit, wireless communication circuit, imaging circuit, and output circuit to set blind spots based on obstacle size and position, varying the intensity of alerts depending on the object's location relative to the vehicle, with stronger alerts for objects in blind spots and weaker alerts for objects outside them.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If alerts are issued every time other vehicles or pedestrians are detected around the vehicle, then driver awareness of surrounding objects is improved, but driver attention deteriorates due to habituation to frequent alerts
Solution Approach 1:
The patent applies local quality by differentiating alert intensity based on the spatial location of detected objects. Objects within blind spots receive stronger alerts (first intensity) while objects outside blind spots receive weaker alerts (second intensity). This localized differentiation maintains driver awareness for critical blind spot objects while reducing habituation effects from less critical alerts elsewhere.
Solution Approach 2:
The patent implements dynamics by making alert intensity variable rather than fixed. The output circuit dynamically adjusts between first intensity and second intensity based on real-time determination of object location relative to blind spots. This dynamic adaptation prevents driver habituation while maintaining reliable awareness of surrounding objects.
2Reliability
If strong alerts are issued for all detected objects, then driver attention is maintained, but driver annoyance increases leading to alert disregard
Solution Approach 1:
The patent applies local quality by issuing strong alerts (first intensity) only for objects in blind spots where driver attention is critically needed, while issuing weaker alerts (second intensity) for objects outside blind spots. This localized approach maintains necessary driver attention while reducing overall driver annoyance from excessive strong alerts.
Solution Approach 2:
The patent applies partial action by providing full-strength alerts only when necessary (for blind spot objects) and reduced-strength alerts for other cases. This partial application of strong alert intensity prevents driver annoyance while maintaining reliability for critical situations.
3Ease of operation
If weak alerts are issued for all detected objects, then driver annoyance is reduced, but driver awareness of critical blind spot objects deteriorates
Solution Approach 1:
The patent applies local quality by providing weak alerts (second intensity) for objects outside blind spots where driver comfort is prioritized, while providing strong alerts (first intensity) for objects within blind spots where driver awareness is critical. This spatial differentiation maintains both comfort and reliability appropriately.
Solution Approach 2:
The patent applies partial action by providing full-strength alerts only for the specific case of blind spot objects where reliability is paramount, while using reduced-strength alerts for other cases. This ensures driver comfort is maintained overall while reliability is preserved for critical situations.

AI summary
A vehicle include a first wheel and a second wheel, a steering circuit configured to steer at least one of the first wheel and the second wheel, and a wireless communication circuit configured to wirelessly communicate with the first vehicle and the second vehicle. When the wireless communication circuit receives a scheduled route of the first vehicle from the first vehicle while the vehicle is traveling on a first scheduled route, and determines that a possibility of a collision with the first vehicle is equal to or greater than a certain value based on the first scheduled route and the scheduled route of the first vehicle. The vehicle creates a second scheduled route different from the first scheduled route, starts traveling on the second scheduled route, and transmits the scheduled route of the first vehicle and the second scheduled route to the second vehicle.
