Vehicle Object Detection Under Exogenous Noise Restrictions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing object detection systems in vehicles face challenges in effectively notifying users when the object detection function is restricted due to exogenous noise, leading to reduced user convenience and potential misidentification of sensor reliability.
Innovation Solution
The object detection device includes an object detection determination unit, a noise state determination unit, and a noise notification processing unit that differentiate between detection and non-detection states and adjust noise-related notifications based on the noise state and vehicle running conditions, ensuring more timely and relevant notifications when the object detection function is restricted.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If noise-related notifications are executed uniformly regardless of detection state, then noise resistance is improved, but user convenience deteriorates due to unnecessary notifications
Solution Approach 1:
The patent applies local quality by differentiating notification execution based on the detection state. When an object is detected, noise-related notifications are executed to alert users of potential false alarms. When no object is detected, notifications are suppressed to avoid unnecessary user alerts. This localized adjustment of notification behavior based on the specific detection context resolves the contradiction between maintaining noise resistance and preserving user convenience.
2Ease of operation
If noise-related notifications are suppressed in non-detection state, then user convenience is improved, but reliability deteriorates due to potential missed notifications
Solution Approach 1:
The patent implements dynamics by making the notification execution state variable rather than fixed. The notification processing unit dynamically adjusts whether to execute noise-related notifications based on the current detection state determined by the object detection determination unit. This dynamic adaptation allows the system to maintain reliability when needed (detection state) while improving convenience when appropriate (non-detection state).

AI summary
An object detection device is provided with a noise state determination unit and a noise information processing unit. The noise state determination unit determines whether a reception state of exogenous noise in an object detecting sensor is a high noise state, while the object detection condition is valid. When it is determined that the noise notification processing unit is a high noise state, noise related notification corresponding to a generation of a restriction in the object detection function as a result of the high noise state is executed. The object detection device provides a difference in the noise related notification depending on a detection state of an object and a running state of an own vehicle.
