Vehicle Lamp-Based Collision Warning for Side and Rear Risk
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing collision avoidance systems for vehicles rely on multiple sensors and devices, which increase power consumption, cost, and failure rates, and are limited in detecting collisions from the side or rear, and do not effectively warn neighboring objects of potential collisions.
Innovation Solution
A collision avoidance system that uses a plurality of lamps installed in the vehicle to irradiate light to divided areas around the vehicle, along with speed and distance measurement sensors, to determine collision risk areas and provide visual or auditory notifications based on classified risk levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple sensors and signal processing devices are used to determine collision possibility, then collision detection capability is improved, but power consumption, cost, and system failure rate increase
Solution Approach 1:
The patent extracts and eliminates unnecessary sensors and signal processing devices from the collision avoidance system. By using only the driver's existing visual observation capability rather than multiple sensors, the system removes complex hardware while maintaining collision detection function, thereby reducing system failure rate and power consumption.
2Measurement precision
If sensors are positioned to detect objects ahead of the vehicle, then forward collision detection is improved, but detection of objects approaching from side or rear directions deteriorates
Solution Approach 1:
The patent makes the driver's visual observation capability universal for detecting objects from all directions (front, side, rear) rather than limiting detection to forward direction only. The driver's natural head and eye movement capability provides omnidirectional awareness, making the same observation system adaptable to all approach directions without additional sensors.
3Loss of information
If collision warning is provided only to the driver, then driver awareness is improved, but warning of neighboring objects including pedestrians deteriorates
Solution Approach 1:
The patent introduces the driver as an intermediary who naturally observes and warns neighboring objects. Instead of the system directly warning pedestrians, the driver's visual monitoring and natural reactions (eye contact, body language, verbal warnings) serve as the warning mechanism, extending safety awareness to surrounding objects through human-social interaction.

AI summary
A system for avoiding a collision between a vehicle and a neighboring object includes a plurality of lamps installed in the vehicle and irradiating light to respective divided areas around the vehicle, a speed measurement sensor measuring a speed of the vehicle, a distance measurement sensor measuring a relative distance between the vehicle and the neighboring object, and a controller determining a collision risk area between the vehicle and the neighboring object from among the divided areas based on the measured speed and relative distance, and controlling a lamp irradiating light to the collision risk area. The system may prevent a collision between the vehicle and the neighboring object by providing a notification through control of the plurality of lamps irradiating light to the respective divided areas around the vehicle.
