Driving Support System Filtering Nonpriority Vehicle Alerts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing driving supporting systems often notify priority vehicles of nonpriority vehicles more frequently than necessary, leading to driver annoyance and potential false alerts.
Innovation Solution
A vehicle-mounted and road-installed driving supporting system that determines the necessity of driving support based on the communication capabilities and specifications of nonpriority vehicles, ensuring that support is only provided when necessary, thereby reducing unnecessary notifications to priority vehicles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If driving support information is transmitted to all nonpriority vehicles, then collision prevention capability is improved, but driver annoyance increases due to unnecessary notifications
Solution Approach 1:
The system changes the parameter of information transmission by checking the communication capability specification of each nonpriority vehicle before transmitting driving support information. Information is only transmitted to vehicles that can receive and process it, thereby preventing unnecessary notifications to incompatible vehicles while maintaining collision prevention capability for capable vehicles.
2Reliability
If driving support is provided to priority vehicles for all nonpriority vehicle entries, then safety is improved, but false alerts increase reducing system reliability
Solution Approach 1:
The system performs preliminary checking of the nonpriority vehicle's communication capability specification before providing driving support to the priority vehicle. By determining in advance whether the nonpriority vehicle can receive driving support information, the system avoids generating false alerts for vehicles that would have self-managed their safety, thereby reducing unnecessary notifications while maintaining safety for vehicles that need support.

AI summary
A vehicle-mounted driving supporting device 2 supports driving on the basis of the presence of a nonpriority vehicle A entering a priority road 50 from a nonpriority road 40. The vehicle-mounted driving supporting device 2 includes an information provision determination device 34 which, when a host vehicle is traveling on the priority road 50, determines whether or not driving support is required on the basis of the specification regarding driving support of the nonpriority vehicle A received from the outside. Therefore, it is possible to avoid a driver from feeling bothered.
