Vehicular Communication System Interoperation Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drivers face difficulty in concentrating on driving due to the need to operate applications on portable terminal devices while they are intended to interoperate with vehicular communication systems, leading to potential safety hazards.
Innovation Solution
A vehicular communication system that includes a vehicular communication apparatus and a portable terminal apparatus, where the system detects an interoperation state and restricts the portable terminal from performing operations for the interoperation function, ensuring safe interaction between applications on both devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the portable terminal apparatus allows full operation of applications for interoperation with vehicular applications, then the ease of operation and functionality are improved, but driver safety deteriorates due to distraction
Solution Approach 1:
The operation input disable device dynamically adjusts the operational state of the mobile input device based on the interoperation state detection. When interoperation is active, the device disables certain input operations; when interoperation is inactive, full operations are permitted. This dynamic adaptation resolves the contradiction by making the system flexible rather than statically restrictive or permissive.
Solution Approach 2:
The operation input disable device selectively disables only specific operations on the mobile input device that are related to the interoperation function, while leaving other operations unaffected. This localized restriction approach maintains driver safety for critical functions while preserving ease of operation for non-critical functions, rather than applying a blanket disablement.
2Reliability
If the system disables operations on the portable terminal during interoperation, then driver safety is improved, but the functionality and ease of operation deteriorate
Solution Approach 1:
The system dynamically switches between disabled and enabled states based on the interoperation detection. The operation input disable device activates restrictions only when needed (during interoperation) and deactivates them when not needed, thereby minimizing the impact on ease of operation while maintaining driver safety when required.
Solution Approach 2:
The disablement is applied locally to only those specific operations that interfere with driver safety during interoperation, rather than disabling all operations on the portable terminal. This selective approach preserves necessary functionality while addressing safety concerns.
3Reliability
If the system monitors and detects interoperation state continuously, then the reliability of safety control is improved, but the device complexity and energy consumption increase
Solution Approach 1:
The interoperation detection device automatically monitors and detects the interoperation state without requiring external intervention or complex manual monitoring systems. The system self-manages the detection and triggers the appropriate disable/enable actions autonomously, reducing the need for additional complex control mechanisms while maintaining high reliability.

AI summary
A vehicular communication system includes: a vehicular communication apparatus; and a portable terminal apparatus. The vehicular communication apparatus includes: a vehicular storage device that stores a predetermined vehicular application for a predetermined function; and a vehicular input device that enters an operation for the predetermined function. The portable terminal apparatus includes: a mobile storage device that stores a predetermined mobile application for the predetermined function; a mobile input device that enters an operation for the predetermined function; an interoperation detection device that detects establishment of an interoperation state, in which the predetermined vehicular application and the predetermined mobile application interoperate with each other; and an operation input disable device that prevents the mobile input device from entering the operation when the interoperation detection device detects the establishment of the interoperation state.
