Vehicle Communication System for Inter-Vehicle Event Mapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current information collection systems for vehicle positioning lack efficient methods to accurately identify and record inter-vehicle communication events, such as turn intentions and expressions of gratitude, without requiring direct information exchange between vehicles.
Innovation Solution
A communication system comprising first and second communication devices on vehicles, which transmit and receive specific information, including turn intentions and gratitude messages, and position data, allowing an information collection device to record these interactions without direct vehicle communication, using Bluetooth Low Energy for short-range communication and cellular networks for longer-range data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If vehicles directly exchange information to identify communication events, then data reliability is improved, but device complexity and communication overhead increase
Solution Approach 1:
The patent introduces a server as an intermediary that collects position information from multiple vehicles and determines communication events centrally. Instead of vehicles directly exchanging and verifying communication data, the server acts as a mediator that receives position data from both transmitting and receiving vehicles, then determines whether communication events occurred based on position relationships. This reduces communication system complexity while maintaining data reliability through centralized verification.
Solution Approach 2:
The patent extracts the communication event determination function from the vehicle systems and relocates it to the server. The vehicle's determination unit is replaced by a server-based determination mechanism that analyzes position information collected from multiple sources. This extraction reduces the computational burden and complexity of individual vehicle systems while centralizing the reliable determination of communication events.
2Measurement precision
If comprehensive position data is collected from multiple vehicles to map communication events, then measurement precision is improved, but loss of time increases due to data collection overhead
Solution Approach 1:
The patent implements preliminary action by having vehicles continuously transmit their position information to the server in advance, before communication events need to be determined. The server maintains an up-to-date database of vehicle positions, so when a communication event needs to be verified, the position data is already available without requiring additional real-time data collection. This preliminary data collection improves measurement precision while minimizing time loss during actual event verification.
Solution Approach 2:
The patent ensures continuous transmission of position information from vehicles to the server, creating an ongoing stream of useful data. Rather than collecting position data intermittently or on-demand, the system maintains continuous position tracking, which provides precise measurement data when needed without incurring repeated data collection delays. This continuous action balances precision requirements with time efficiency.

AI summary
An information collection system includes a first communication device provided at a first vehicle including a processor configured to execute a process. The process includes receiving operations by a first input section, and wirelessly transmitting, by a first transmission section, specific information according to the operation received by the first input section. The information collection system further includes a second communication device provided at a second vehicle including a processor configured to execute a process. The process includes receiving, by a first reception section, the specific information transmitted by the first transmission section, and wirelessly transmitting, to a device that is different from the first communication device by a second transmission section, position information enabling identification of a position at which the specific information was received by the first reception section.
