Driving Assistance Route Prediction to Avoid False Interference Alerts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing preventive safety technologies for driving assistance in vehicles lack effective methods to predict and notify drivers of potential interference with other vehicles, especially when a preceding vehicle is present.
Innovation Solution
A driving assistance device that calculates the travel route of other vehicles through vehicle-to-vehicle communication and determines if the self-vehicle interferes with them, generating a notification signal when interference is predicted. The device is deactivated when a preceding vehicle is within a predetermined distance, preventing unnecessary notifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the arithmetic unit is always active to detect potential interference with other vehicles, then driving safety is improved, but false notifications occur when a preceding vehicle is present causing driver distraction
Solution Approach 1:
The system changes the operational state parameter of the arithmetic unit based on the presence parameter of a preceding vehicle. When a preceding vehicle is detected within a predetermined distance, the arithmetic unit transitions from an active state to a deactivated state, preventing false notifications while maintaining safety monitoring when the road is clear

AI summary
A driving assistance device mounted on a vehicle capable of communicating with another vehicle, comprising a calculation unit configured to calculate a travel route of the other vehicle based on a result of the communication with the other vehicle, and an arithmetic unit configured to determine whether the self-vehicle interferes with the other vehicle traveling on the calculated travel route, and generate a notification signal for notifying that the self-vehicle interferes with the other vehicle when it is determined that the self-vehicle interferes with the other vehicle, wherein the arithmetic unit is deactivated when a preceding vehicle traveling in a direction equivalent to a direction of the self-vehicle is within a range of a predetermined distance from the self-vehicle.
