Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In inter-vehicle communication systems, maintaining a constant connecting state for emergency information transfer can lead to communication resource bottlenecks, such as wireless band and capacity shortages, hindering timely information exchange.
Innovation Solution
An inter-vehicle communication device that dynamically switches between a standby state and a connecting state based on predetermined conditions, such as proximity and speed of adjacent vehicles, to optimize resource utilization and ensure timely information exchange.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If each vehicle constantly holds the connecting state to exchange operation information through the wireless communication network, then the information can be transferred instantly when needed, but communication resources such as wireless band and communication capacity become tight
Solution Approach 1:
The patent applies dynamics by making the communication state changeable rather than fixed. The terminal device dynamically switches between standby state and connecting state based on whether emergency information needs to be transferred. This resolves the contradiction by allowing fast information transfer only when necessary, while conserving communication resources during normal operation.
Solution Approach 2:
The patent changes the communication state parameter between two discrete values: standby state and connecting state. By switching this parameter based on information transfer needs, the system achieves instant information transfer capability when required while preventing communication resource tightness during normal operation, thus resolving the technical contradiction.
2Quantity of substance
If the terminal device switches to standby state to conserve communication resources, then communication resources remain available, but it takes 100 milliseconds to a few seconds to switch from standby state to connecting state when emergency information needs to be transferred
Solution Approach 1:
The patent applies preliminary action by pre-establishing the capability to switch states. The terminal device maintains the ability to quickly transition from standby to connecting state through pre-configured communication protocols and network registration mechanisms. This allows the system to conserve resources in standby while ensuring that when emergency information transfer is needed, the switching process can be completed within 100 milliseconds to a few seconds rather than taking much longer.
3Loss of energy
If communication is performed only when absolutely necessary, then communication resources are not wasted, but the system cannot respond instantly to emergency situations requiring immediate information exchange
Solution Approach 1:
The patent applies feedback by continuously monitoring whether emergency information transfer conditions are met. Based on this feedback, the terminal device automatically switches between standby state and connecting state. This ensures that communication resources are conserved during normal operation while guaranteeing that the system can immediately respond to emergency situations, thus resolving the contradiction between resource efficiency and emergency response reliability.

AI summary
A communication device (202) for performing communication with other vehicle through a wireless communication network which performs communication by switching a communication state to a standby state or to a connecting state, and a state setting means (208) for selectively setting a state of the communication device to the standby state or to the connecting state are provided, wherein the state setting means judges whether or not at least one predetermined condition is met based on the information on an own vehicle and/or the information on other vehicle, sets the communication device to the connecting state when the condition is met, and sets the communication device to the standby state provided that the condition is not met.
