Blind-Spot Detection System Side Mirror Failure Warning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional blind-spot detection systems for vehicles make it difficult for drivers to reliably perceive failures in the obstacle indicator due to its placement and the presence of multiple warning systems, leading to potential unnoticed failures.
Innovation Solution
A blind-spot detection system with a module that detects obstacles and displays information on the side mirror, including obstacle existence, distance, and relative speed, and includes abnormality detection and warning means on the side mirror to visually indicate any failures, allowing simultaneous recognition with the obstacle display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the failure warning unit is mounted on the instrument panel together with other warning means, then the system can warn of failures, but the driver cannot readily perceive the failure in the obstacle indicator due to multiple warning means and separated layout
Solution Approach 1:
The patent combines the obstacle indicator display and the failure warning unit into a single integrated display unit mounted on the instrument panel. This merging allows the driver to perceive both obstacle information and system failure status at one location, eliminating the need to check separate locations and improving both reliability of failure perception and ease of driver monitoring.
2Loss of information
If the obstacle indicator is mounted on the side mirror, then obstacle information is displayed, but the driver cannot simultaneously check both the display and failure warning unit
Solution Approach 1:
The patent merges the failure warning unit with the obstacle indicator display into a single integrated unit. This allows the driver to access both obstacle information and failure status simultaneously at one location, reducing the time required to check system status and ensuring no information is lost due to spatial separation.
3Adaptability or versatility
If multiple warning means are present on the instrument panel, then various system failures can be warned, but the driver has difficulty distinguishing the obstacle indicator failure from other warnings
Solution Approach 1:
The patent applies local quality by providing a dedicated, distinct visual indication specifically for obstacle indicator failures within the integrated display unit. This localized failure indication differs from other warning means, allowing the driver to easily identify obstacle indicator failures among multiple warning types while maintaining comprehensive warning coverage for various systems.

AI summary
Disclosed is a BSD system for vehicle provided with a blind spot detection module which includes obstacle in blind spot detection unit for detecting an obstacle existing in a blind spot around the rear side of a self vehicle and an obstacle indicator disposed on a side mirror of the self vehicle and adapted to display at least one of information for the existence of an obstacle in the blind spot, for a distance between the obstacle and the self vehicle, and for a relative speed of the obstacle to the self vehicle, the blind-spot detection system for vehicle. This system is provided with a unit for detecting that the blind spot detection module is in an abnormal operation state and a unit disposed on the side mirror having the obstacle indicator and adapted to visually indicate an abnormality of the blind spot detection module detected by the abnormality detection unit.
