Solution Overview
Problem
The increasing amount of data transmitted and received through road-vehicle wireless communication systems poses a challenge, as it can overwhelm the communication capacity of both in-vehicle and roadside devices, leading to potential data handling issues.
Innovation Solution
An in-vehicle wireless communication device that determines the communication amount within the vehicle's network and transmits this information to external devices, allowing for data compression and prioritization to match available communication capacity, thereby optimizing data transmission and reception.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the amount of data transmitted and received through road-vehicle wireless communication increases to support sophisticated services, then service functionality is improved, but communication capacity is overwhelmed leading to data handling issues
Solution Approach 1:
The in-vehicle wireless communication device performs preliminary determination of the communication amount in the in-vehicle network before receiving data from external devices. By calculating and notifying the communication amount in advance, the system prepares the external device to transmit appropriately sized data, preventing communication overload before it occurs.
Solution Approach 2:
The system implements a feedback mechanism where the in-vehicle wireless communication device notifies the external device of the determined communication amount. This feedback loop allows the external device to adjust its data transmission size according to the actual communication capacity of the in-vehicle network, ensuring reliable data handling.
2Quantity of substance
If data transmission size is increased to provide more comprehensive services, then service quality is improved, but data overflow occurs overwhelming the communication system
Solution Approach 1:
The system calculates the communication amount in the in-vehicle network before data transmission from external devices. By determining the maximum acceptable data size in advance and notifying the external device, the system prevents data overflow by ensuring that transmitted data volume matches the actual communication capacity.
3Loss of information
If the communication amount in the in-vehicle network is not controlled, then data completeness is maintained, but communication capacity is exceeded causing system overload
Solution Approach 1:
The in-vehicle wireless communication device performs preliminary calculation of the communication amount in the in-vehicle network before receiving external data. This advance determination allows the system to control incoming data volume to match actual communication capacity, preventing system overload while maintaining data completeness within the manageable communication amount.
