Vehicle Detection Information Sharing via Risk Degree Calculation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle detection systems struggle to effectively share detection information about movable obstacles, such as animals, with other vehicles, leading to difficulties in appropriate risk avoidance actions, especially when multiple vehicles are involved and communication limitations exist.
Innovation Solution
A vehicle detection information sharing system that includes a detection information acquiring unit, a vehicle information acquiring unit, a risk degree calculator, and an information transmitter. This system acquires detection information on obstacles from one vehicle, acquires vehicle information from other vehicles, calculates a risk degree based on this information, and transmits risk avoidance information to affected vehicles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If detection information is shared among multiple vehicles, then safety improves through better risk avoidance, but communication limitations and information accuracy deteriorate
Solution Approach 1:
The server acts as an intermediary that collects detection information from multiple vehicles, calculates comprehensive risk degrees, and transmits standardized risk avoidance information back to vehicles. This mediator resolves the contradiction by centralizing information processing to maintain accuracy while enabling widespread sharing.
Solution Approach 2:
The system implements feedback loops where detection information is continuously shared among vehicles via the server, risk degrees are recalculated based on updated information, and risk avoidance measures are adjusted accordingly. This feedback mechanism maintains information accuracy while enabling continuous safety improvements.
2Measurement precision
If risk degree calculation considers multiple vehicles and obstacles, then risk assessment accuracy improves, but system complexity increases
Solution Approach 1:
The system segments the complex risk assessment task by having each vehicle independently calculate its own risk degree based on received detection information and its own vehicle state. This divides the overall complex calculation into simpler individual calculations, improving accuracy through comprehensive data while reducing individual system complexity.
Solution Approach 2:
The server serves as a mediator that collects detection information from multiple vehicles and distributes it to relevant vehicles. This intermediary approach simplifies the system architecture by centralizing information management while enabling accurate multi-vehicle risk assessment without requiring direct complex interactions between all vehicles.
3Reliability
If detection information is transmitted to all vehicles, then risk avoidance coverage improves, but communication energy consumption increases
Solution Approach 1:
Instead of uniformly transmitting information to all vehicles, the system applies local quality by sending risk avoidance information only to vehicles that are actually at risk based on calculated risk degrees. This targeted approach improves risk avoidance coverage for affected vehicles while minimizing unnecessary communication energy consumption.
Solution Approach 2:
The system transmits detection information to the server and receives risk avoidance information selectively based on calculated risk levels. This partial action approach avoids the excessive energy consumption of universal transmission while ensuring all vehicles receive necessary information for their specific risk situations.

AI summary
A vehicle detection information sharing system includes a detection information acquiring unit, a vehicle information acquiring unit, a risk degree calculator, and an information transmitter. The detection information acquiring unit is configured to acquire detection information on an obstacle detected by a first vehicle traveling on a road. The vehicle information acquiring unit is configured to acquire vehicle information on a second vehicle traveling on the road. The risk degree calculator is configured to calculate a risk degree on the basis of the detection information and the vehicle information. The risk degree is a degree of risk that arises between the second vehicle and the obstacle. The information transmitter is configured to transmit, to the second vehicle, risk avoidance information corresponding to the risk degree.
