Child Protection Zone Blind-Spot Pedestrian Warning via V2X
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies lack the capability to easily detect pedestrians in blind spots around vehicles traveling in child protection zones, leading to a high risk of accidents even at low speeds.
Innovation Solution
A driving assistance device and method utilizing a surveillance camera and vehicle-to-everything (V2X) communication to recognize pedestrians in blind spots and display their location on a vehicle's display device, enabling the vehicle to potentially adjust its trajectory or speed to avoid collisions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If drivers slow down in child protection zones to prevent accidents, then safety is improved, but traffic efficiency deteriorates
Solution Approach 1:
The system performs preliminary detection of pedestrians in blind spots using surveillance cameras and V2X communication before the vehicle reaches them. By identifying potential hazards in advance and providing warning information to the driver, the system enables proactive safety measures without requiring continuous speed reduction, thus maintaining traffic efficiency while improving safety.
2Productivity
If drivers maintain normal speed in child protection zones, then traffic efficiency is improved, but safety deteriorates due to blind spots
Solution Approach 1:
The system introduces an intermediary detection mechanism (surveillance cameras and V2X communication infrastructure) that acts as a mediator between the driver and pedestrians in blind spots. This intermediary system detects and communicates pedestrian locations to the driver, compensating for the driver's limited visibility without requiring speed reduction, thereby maintaining both safety and traffic efficiency.
3Device complexity
If no detection technology is used, then device complexity is reduced, but the ability to detect pedestrians in blind spots deteriorates
Solution Approach 1:
The system uses external surveillance cameras and V2X communication infrastructure as intermediaries to detect pedestrians in blind spots. This approach transfers the detection burden from the vehicle's own sensors to external infrastructure, enabling effective pedestrian detection without significantly increasing the complexity of the vehicle's detection system.
4Difficulty of detecting and measuring
If surveillance cameras and V2X communication are implemented, then pedestrian detection capability is improved, but device complexity increases
Solution Approach 1:
The system leverages external surveillance cameras and V2X communication infrastructure as intermediaries, which are deployed in the environment rather than on the vehicle itself. This allows the vehicle to benefit from enhanced detection capabilities while minimizing the addition of complex detection hardware to the vehicle.
Solution Approach 2:
The system uses a general-purpose display device already present in the vehicle to present the detection information. By reusing existing vehicle components for the warning function, the system avoids adding dedicated complex hardware, thereby improving pedestrian detection capability while limiting the increase in overall device complexity.
Data Source
AI summary
A child protection zone driving assistance device includes a transceiver configured to receive image data received from a surveillance camera having a constant sensing field of view within a child protection zone from a communication device and a processor configured to recognize a pedestrian based on the image data, determine location information about the pedestrian as either left or right based on a driving direction when the pedestrian is recognized, and control a display device of a vehicle to display the determined location information, and may display a location of the pedestrian present in a blind spot in the child protection zone as left or right based on the driving direction of the vehicle together with a warning, thereby encouraging safe driving and improving driving convenience.
