Parked Vehicle Warning System for Night Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Freight vehicles parked on roads pose a risk of accidents at night due to their large size occupying outer lanes, leading to potential collisions with approaching vehicles, as drivers may not notice them, especially when parked far from general parking lots due to logistical constraints.
Innovation Solution
An apparatus and method that includes cameras to identify approaching objects, blinking lamps, and radar to measure speed, which selectively activate lamps and a buzzer to alert approaching vehicles, preventing accidents by enhancing visibility and awareness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If freight vehicles are parked on secluded roads closer to drivers' homes, then the driver's time and livelihood are improved, but the risk of traffic accidents increases due to reduced visibility and awareness of the parked vehicle by approaching drivers
Solution Approach 1:
The system performs preliminary detection of approaching vehicles using cameras and radar before a collision risk arises. When a vehicle is detected approaching the parked freight vehicle, the system proactively activates warning lamps and buzzers to alert the approaching driver in advance, preventing the accident before it happens.
Solution Approach 2:
The patent introduces an intermediary warning system consisting of lamps and buzzers that mediate between the parked freight vehicle and approaching vehicles. This intermediary device communicates the presence of the parked vehicle to approaching drivers, resolving the visibility and awareness problem without requiring the approaching driver to directly see or notice the parked vehicle.
2Ease of operation
If freight vehicles occupy the outermost lane of a road, then the vehicle can be parked closer to the curb, but the visibility to approaching drivers is reduced and accident risk increases
Solution Approach 1:
The warning system acts as an intermediary that compensates for the reduced visibility caused by parking in the outermost lane. The lamps and buzzers actively communicate the vehicle's presence to approaching drivers, making the parked vehicle noticeable despite its position in the outer lane where it would otherwise be less visible.
Solution Approach 2:
The system detects approaching vehicles in advance and activates warning signals before the approaching vehicle reaches a dangerous proximity. This preliminary warning allows approaching drivers to adjust their behavior in time, preventing collisions even when the parked vehicle is in a position with naturally reduced visibility.
3Device complexity
If no warning system is installed on parked freight vehicles, then the device complexity is minimized, but the safety of surrounding vehicles and pedestrians is compromised
Solution Approach 1:
The patent introduces a relatively simple intermediary warning system with cameras, radar, lamps, and buzzers. This system provides a practical balance between complexity and safety by using off-the-shelf components arranged in a straightforward detection-and-warning architecture, achieving significant safety improvement without requiring overly complex systems.
Solution Approach 2:
The parked freight vehicle serves itself by automatically detecting approaching vehicles and activating warning signals without human intervention. The system monitors the environment continuously and autonomously responds to potential hazards, providing safety service to surrounding traffic without requiring the driver's attention or action.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively prevents traffic accidents by ensuring that approaching vehicles are alerted to parked freight vehicles through visual and auditory cues, improving safety and reducing the risk of collisions.
Implementation Method 1
a camera provided in the vehicle and configured to photograph a surrounding image
Implementation Method 2
a radar configured to measure a speed of the surrounding vehicle approaching the parked vehicle
Implementation Method 3
a plurality of lamps mounted on an external portion of a vehicle

AI summary
An apparatus and a method for inducing safe driving of a surrounding vehicle are applied to a vehicle parked on a road and may identify an object (surrounding vehicle, pedestrian) based on an image obtained by a camera photographing an approaching object. The apparatus and method blink a lamp of the parked vehicle according to the identified object, thus preventing a traffic accident occurring due to the parked vehicle. The apparatus includes: a plurality of lamps mounted on an external portion of the parked vehicle; a camera provided in the parked vehicle and configured to photograph a surrounding image; and a controller configured to identify an object approaching the parked vehicle in the surrounding image photographed by the camera and blink at least one lamp according to the identified object.
