Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Vehicle-to-Everything (V2I) technologies fail to incorporate information from pedestrians, bikers, and vehicles without V2X devices into the Internet of vehicles, limiting the comprehensive sensing of road participants and traffic safety.
Innovation Solution
A safe passing system that includes a road ambient environment sensing system and a vehicle-mounted terminal, utilizing scanning devices and data processing modules to acquire and process information from all road participants, including those without V2X devices, and transmit this information to vehicles equipped with V2X devices for enhanced route planning and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If V2I technology uses only built-in V2X devices of vehicles for information acquisition, then the system complexity is reduced, but the measurement precision and completeness of road participant information is insufficient
Solution Approach 1:
The patent introduces roadside infrastructure (radar, cameras, processors) as an intermediary to detect and transmit information about road participants without V2X devices. This mediator bridges the gap between participants who cannot communicate directly via V2X and the central system, enabling comprehensive information acquisition without requiring every participant to have complex V2X equipment.
Solution Approach 2:
The roadside infrastructure serves multiple functions: detecting vehicles with V2X devices, detecting vehicles without V2X devices, detecting pedestrians and cyclists, and transmitting all this information to the central system. This multi-functional approach improves information completeness without proportionally increasing system complexity.
2Reliability
If all road participants are equipped with V2X devices, then the reliability of information exchange is improved, but the loss of substance (equipment cost and deployment complexity) increases
Solution Approach 1:
The roadside infrastructure acts as a mediator that detects and tracks road participants without V2X devices, relaying this information to the central system. This allows reliable information exchange about all participants without requiring expensive V2X equipment in every vehicle, pedestrian, or cyclist.
Solution Approach 2:
The system creates a virtual representation (copy) of road participants without V2X devices through roadside detection. Instead of equipping each participant with V2X hardware, the system creates digital copies of their positions and movements through infrastructure-based sensing, achieving similar information exchange reliability at lower cost.
3Productivity
If the system incorporates information from all road participants including those without V2X devices, then the productivity of traffic management is improved, but the device complexity of the sensing system increases
Solution Approach 1:
The system segments the detection function between roadside infrastructure (radar, cameras) and the central processing system. The roadside components handle data collection while the central system performs integration and analysis, improving traffic management productivity without concentrating all complexity in one location.
Solution Approach 2:
The roadside infrastructure is designed to detect multiple types of road participants (vehicles, pedestrians, cyclists) simultaneously using integrated sensor suites. This multi-functional approach improves comprehensive traffic monitoring productivity without proportionally increasing system complexity through standardized detection platforms.
