Remote Driving Assistance for Camera Shielding at Intersections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing driving support systems struggle to safely navigate vehicles through intersections when obstacles like trees or construction barriers obstruct the camera's view, leading to potential undetection of target vehicles and reduced safety.
Innovation Solution
A driving support method and system that uses a camera outside the vehicle to recognize shielding areas within its imaging range and issues commands to the vehicle to adjust its path or speed, such as deceleration, path change, or target point alteration, to avoid obstructed areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a camera is used to detect vehicles at intersections, then the system complexity is reduced compared to using multiple radar sensors, but the detection reliability deteriorates when shields (trees, parked vehicles) obstruct the camera view
Solution Approach 1:
The system performs preliminary recognition of shielding areas using the camera before making driving support decisions. By identifying regions where shields block the camera view in advance, the system can proactively adjust vehicle control commands to avoid these areas, thereby maintaining detection reliability while using a simpler camera-based setup compared to multiple radar sensors
Solution Approach 2:
The shielding area recognition function acts as an intermediary between the camera detection system and the vehicle control system. It processes camera images to identify blocked regions and translates this information into control commands that guide the vehicle around shielding areas, effectively bridging the gap between limited camera visibility and safe navigation requirements
2Reliability
If shielding areas are recognized and avoided by changing vehicle path, then collision risk is reduced, but the driving time increases due to path adjustments
Solution Approach 1:
The system applies path adjustment commands selectively only when shielding areas are detected on the vehicle's current or predicted path. Instead of continuously deviating from the optimal path, the system makes partial adjustments only in necessary segments, thereby maintaining collision avoidance capability while minimizing unnecessary time loss during clear driving conditions

AI summary
A driving support method supports driving of a vehicle from outside of the vehicle using images captured by a camera installed outside of the vehicle. The driving support method includes a recognition step of recognizing a shielding area that is an area in which a vehicle is shielded by a shield within an imaging range of the camera based on the images, and a control step of controlling the behavior of the vehicle by giving a predetermined command to the vehicle when a shielding area is present on traveling path of the vehicle.
