Vehicle Collision Avoidance via Hazard Light Blinking Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle collision avoidance technologies fail to promptly respond to sudden changes in a preceding vehicle's movement, especially when traveling at high velocities or in congested areas, leading to potential collisions.
Innovation Solution
A system and method that utilizes an image sensor and controller to recognize blinking hazard lights of a preceding vehicle, triggering driver warnings and deceleration controls when the vehicle is traveling at high speed or in congested conditions, even if the preceding vehicle's movement appears unchanged or subtly changing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If only movement change of preceding vehicle is sensed for collision avoidance control, then the control system is simple, but it cannot respond to sudden movement changes when the preceding vehicle is likely to change movement despite no change or subtle change in movement
Solution Approach 1:
The system performs preliminary action by detecting hazard light blinking of the preceding vehicle before actual movement change occurs. The control apparatus monitors hazard light signals and predicts potential sudden stops or lane changes, enabling preventive collision avoidance control before the preceding vehicle actually changes its movement pattern.
2Reliability
If hazard light blinking recognition is added to detect preceding vehicle's intent, then collision avoidance capability is improved, but the system complexity and processing requirements increase
Solution Approach 1:
The system uses hazard light blinking as an intermediary signal to detect the preceding vehicle's intent to change movement. Instead of directly monitoring complex movement patterns, the control apparatus detects the simpler hazard light signal, which serves as a reliable mediator indicating the driver's intention to stop or change lanes, thereby simplifying the detection task while improving reliability.
3Speed
If immediate deceleration control is implemented upon hazard light detection, then collision avoidance is enhanced, but the control response time and processing load increase
Solution Approach 1:
The system performs preliminary detection of hazard light blinking and calculates predicted position and collision risk in advance. This allows the control apparatus to be prepared for immediate deceleration control when collision risk is confirmed, reducing actual response time while maintaining thorough processing for accurate collision prediction.

AI summary
Provided are an apparatus, system, and method for vehicle collision avoidance control. When a velocity of a vehicle is determined to be a control-involved velocity or higher, blinking of hazard lights of a preceding vehicle in front of the vehicle is recognized, and one or more of driver warning and deceleration control are performed on the basis of recognition of blinking of the hazard light of the preceding vehicle. Therefore, it is possible to recognize a probability of vehicle collision and avoid vehicle collision.
