Vehicle Driving Assistance for Tracking Near Road Edges
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lane keeping assistance technologies for vehicles stop or cancel assistance when a vehicle is near a lane boundary or roadway outer line, even if it can safely avoid a preceding vehicle by straddling these lines, leading to potential obstruction of smooth vehicle travel.
Innovation Solution
A driving assistance control apparatus that acquires the vehicle's traveling environment and, when a preceding vehicle is near a road edge and no obstacles are present, performs driving assistance to track the preceding vehicle, allowing the vehicle to travel near the road edge without obstructing other vehicles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If lane keeping assistance stops or cancels when near lane boundary or roadway outer line, then safety is improved by avoiding potential hazards, but productivity deteriorates by obstructing smooth vehicle travel
Solution Approach 1:
The lane keeping assistance system dynamically adjusts its behavior based on real-time detection of preceding vehicles. When a preceding vehicle is detected near the road edge, the system transitions from a static stop/cancel mode to an active tracking mode, allowing the own vehicle to straddle the lane boundary or roadway outer line to maintain smooth travel while avoiding obstacles.
Solution Approach 2:
The system continuously monitors the traveling environment using detectors to identify preceding vehicles and their positions. This feedback mechanism enables the control unit to adjust the driving assistance behavior in real-time, switching between maintaining lane position and tracking preceding vehicles based on detected conditions, thereby resolving the contradiction between safety and smooth travel.
2Reliability
If vehicle maintains position away from road edge, then safety is improved by avoiding road edge hazards, but productivity deteriorates by obstructing following vehicles
Solution Approach 1:
The system dynamically adjusts lateral positioning based on presence of preceding vehicles. When preceding vehicles are detected near the road edge, the own vehicle dynamically shifts position to straddle the lane boundary or roadway outer line, allowing following vehicles to pass smoothly while maintaining safety through continuous environmental monitoring.
Solution Approach 2:
The control unit changes the lateral position parameter of the own vehicle based on detected conditions. When a preceding vehicle is near the road edge, the system changes the target position parameter to allow straddling of the lane boundary or roadway outer line, thereby improving traffic flow efficiency while maintaining safety through adaptive parameter adjustment.
3Productivity
If driving assistance tracks preceding vehicle near road edge, then productivity is improved by enabling smooth travel, but safety deteriorates by potentially approaching hazards
Solution Approach 1:
The system uses continuous feedback from detectors monitoring the traveling environment to safely track preceding vehicles. The control unit adjusts the tracking behavior based on real-time detection of obstacles and road edge conditions, ensuring that productivity improvement through smooth travel does not compromise safety by approaching hazards.
Solution Approach 2:
The system takes preliminary anti-action by continuously detecting the traveling environment and identifying potential hazards before the own vehicle approaches them. This proactive detection allows the system to adjust tracking behavior in advance, maintaining smooth travel while preventing safety issues by anticipating and avoiding road edge hazards.

AI summary
A driving assistance control apparatus for a vehicle includes an acquiring unit and a control unit. The acquiring unit acquires a detected traveling environment of the vehicle. Using the acquired traveling environment, and in response to a preceding vehicle being present near a road edge and no obstacle being present between the road edge and the preceding vehicle, the control unit causes a driving assisting unit to perform driving assistance in which the preceding vehicle is tracked.
