Vehicle Driving Assistance Alert Control for No-Passing Zones
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle driving assistance systems provide unnecessary alerts when a vehicle attempts to pass a preceding vehicle in a no-passing zone, causing driver discomfort due to alerts persisting after the situation changes and becoming unnecessary.
Innovation Solution
A driving assistance apparatus with a start determiner to detect when a vehicle enters a no-passing zone and initiates alerts, and a situation determiner to stop alerts when the situation changes from blocking to non-blocking, using sensors and image data to assess the vehicle's position and roadway conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If alerting is provided to restrict passing driving in the no-passing zone, then safety is improved, but driver discomfort occurs when alerts persist after becoming unnecessary
Solution Approach 1:
The alert control system dynamically adjusts alert provision based on real-time situation assessment. The situation determiner continuously evaluates whether the own vehicle is in a blocking situation (alert necessary) or non-blocking situation (alert unnecessary), and the alert controller activates or deactivates the alert device accordingly. This dynamic adaptation ensures safety alerts are provided only when actually needed, eliminating unnecessary driver discomfort while maintaining safety.
2Reliability
If alerting is provided continuously in the no-passing zone, then safety is ensured, but unnecessary alerts cause driver discomfort
Solution Approach 1:
The system implements feedback control by continuously monitoring the situation and adjusting alert provision. The situation determiner assesses current conditions (positioning information, preceding vehicle status) and provides feedback to the alert controller, which then determines whether to activate or deactivate the alert device. This feedback mechanism ensures alerts are provided only when the situation actually requires them, eliminating unnecessary alerts that cause driver discomfort.
3Measurement precision
If the system determines passing start based on lateral movement, then accuracy is improved, but complexity of detection increases
Solution Approach 1:
The system performs preliminary positioning assessment before detecting passing start. The positioning information acquisition unit continuously obtains the own vehicle's position and the preceding vehicle's position in advance, establishing a baseline for detecting lateral movement. When the own vehicle laterally moves from the rearward position to the lateral position relative to the preceding vehicle, the start determiner can accurately determine passing start based on this pre-established positional context, achieving high accuracy without excessive complexity.

AI summary
In a driving assistance apparatus, a start determiner determines whether or not during travel in a no-passing zone an own vehicle has laterally moved from a rearward position to a lateral position relative to the preceding vehicle, and if the own vehicle has laterally moved, then determine that the own vehicle has started passing driving. If the own vehicle has started passing driving in the no-passing zone, an alert controller starts alerting using an alert device at a start of passing driving. A situation determiner determines whether or not a change of situation from a blocking situation to a non blocking situation has occurred after the start of passing driving. If the change of situation from the blocking situation to the non blocking situation has occurred, an alerting stopper stops alerting using the alert device.
