Lane Guiding Device Warning Control for Lane Change Context
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lane guiding devices issue uncomfortable warnings when a vehicle intentionally travels on a passing lane due to changes in the number of lanes on a route, as they fail to differentiate between intentional and unintentional lane usage.
Innovation Solution
A lane guiding device that uses a warning control unit to set a warning stop range based on vehicle position and road information, avoiding warnings in situations where the lane change is appropriate, such as at branching or merging points, to prevent driver discomfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a warning is issued when a vehicle travels on a passing lane for a predetermined time, then lane guidance is provided to ensure safe driving, but driver discomfort occurs when the vehicle intentionally travels on the passing lane due to lane changes ahead
Solution Approach 1:
The system performs preliminary analysis of road information to detect places where the number of lanes changes ahead. When such places are detected, the warning stop range is set in advance, preventing warnings from being issued during the vehicle's intentional lane usage before the lane change point. This resolves the contradiction by anticipating the driver's intended lane change and avoiding false warnings.
Solution Approach 2:
The system applies different warning behaviors to different spatial locations. By setting a warning stop range based on the detected lane change place, the system creates a localized zone where warning issuance is suspended. This allows normal warning functionality in other areas while preventing discomfort-causing warnings in the specific zone where lane changes are expected.
2Reliability
If warnings are issued to prompt lane changes, then driving safety is improved, but false warnings occur when lane changes are intentionally made ahead
Solution Approach 1:
The system acquires and analyzes road information in advance to detect places where the number of lanes changes. This preliminary detection allows the system to understand the contextual reason for upcoming lane changes before they occur, preventing false warnings by anticipating the driver's intended lane change behavior.
Solution Approach 2:
The system uses acquired road information as feedback to adjust warning issuance behavior. By continuously monitoring road data and detecting lane change places, the system adapts its warning strategy by setting appropriate warning stop ranges, thereby improving warning accuracy while avoiding false alarms.

AI summary
A lane guiding device (100) that performs lane guidance based on a vehicle position and road information acquired by an information acquisition unit (110), the lane guiding device (100) includes a warning control unit (102) configured to control issuing a warning when a lane on which a vehicle is traveling is not a left lane. The warning control unit (102) sets a warning stop range in which the warning is not issued when there is a place where the number of lanes changes on a route of the vehicle based on the vehicle position and the road information acquired by the information acquisition unit (110).
