Vehicle-Specific Obstruction Warnings for Travel Assistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing travel assistance systems fail to provide appropriate notifications of obstruction factors to vehicles, as the same obstruction can be critical for one type of vehicle but not for another, leading to inappropriate judgments and actions.
Innovation Solution
A travel assistance system that includes a server with a recognition unit to identify obstruction factors and an obtainment unit to gather vehicle type information, generating tailored warning information and notifications based on the vehicle type, allowing for appropriate alerts and control actions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the same warning notification is sent to all vehicles regardless of type, then the notification system is simple to implement, but the notification appropriateness deteriorates because different vehicle types have different responses to the same obstruction
Solution Approach 1:
The system sends different types of notifications to different vehicle types based on their specific characteristics. For example, straddle-type vehicles receive warnings about obstructions that require avoidance maneuvers, while four-wheeled vehicles receive different notifications. This local differentiation of notification content according to vehicle type improves notification appropriateness without requiring complete system redesign.
Solution Approach 2:
The notification system dynamically adapts its behavior based on the recipient vehicle type. The server determines the appropriate notification type by identifying the vehicle type and selecting from different notification templates. This dynamic adaptation allows the system to maintain high reliability across different vehicle types while using a standardized communication framework.
2Reliability
If warning notifications are sent to all approaching vehicles, then comprehensive safety coverage is achieved, but unnecessary alerts increase for vehicle types that do not require avoidance actions
Solution Approach 1:
The system applies different notification strategies to different vehicle types. Straddle-type vehicles receive comprehensive warnings about obstructions requiring avoidance, while four-wheeled vehicles receive notifications only when the obstruction actually requires their attention. This local differentiation eliminates unnecessary alerts for vehicle types that would not be affected by the obstruction, while maintaining comprehensive safety coverage for vulnerable vehicle types.
Solution Approach 2:
The system performs partial notification action by selectively sending warnings only to vehicle types that require them. Rather than notifying all vehicles about all obstructions, the server evaluates each vehicle type's susceptibility to the specific obstruction and sends notifications only where necessary. This partial action approach maintains safety coverage for vulnerable vehicles while avoiding excessive notifications to vehicles that would not be affected.

AI summary
A travel assistance system including a server that assists traveling of a vehicle, comprises: a recognition unit configured to recognize an obstruction factor for traveling of the vehicle; an obtainment unit configured to obtain information of an approaching vehicle that approaches the obstruction factor; a generation unit configured to, based on information of the obstruction factor recognized by the recognition unit, generate warning information corresponding to information of a type of the approaching vehicle obtained by the obtainment unit; a transmission unit configured to transmit the warning information to the approaching vehicle; and a control unit configured to give notification to an occupant of the approaching vehicle and/or control traveling of the approaching vehicle based on the warning information.
