Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle control systems fail to effectively manage the passage of multiple moving objects through an intersection when they approach from different directions, increasing the risk of collisions and blocking courses.
Innovation Solution
A control device and method that prioritize the passage of moving objects through an intersection based on their avoidance and collision reduction capabilities, using information such as automatic avoidance functions and reinspection frequency to determine a descending order of priority.

Engineering Contradiction Analysis
1Productivity
If multiple moving objects enter an intersection from different directions at the same time without priority management, then the intersection can be utilized efficiently, but the probability of collision increases and collision impact cannot be controlled
Solution Approach 1:
The control device determines priority orders of moving objects before they reach the intersection based on their capability information. This preliminary assignment of priority ensures that when multiple objects approach simultaneously, the one with higher capability (better avoidance or reduction capability) is granted right of way, preventing collisions while maintaining efficient intersection utilization.
Solution Approach 2:
The system changes the parameter of priority order based on the capability information of moving objects. By dynamically adjusting which object has priority based on their avoidance or reduction capabilities, the system optimizes both safety and efficiency at the intersection without requiring fixed rules.
2Productivity
If a moving object with lower avoidance capability is given priority to pass through the intersection, then the passage efficiency is maintained, but the impact of collision increases when collision occurs
Solution Approach 1:
The priority order parameter is dynamically changed based on the reduction capability of moving objects. When objects have similar avoidance capabilities, the system assigns priority to the object with better reduction capability, thereby minimizing collision impact while maintaining passage efficiency.
Solution Approach 2:
The system converts the potential harm of collision into a beneficial outcome by prioritizing objects with better reduction capability. This ensures that if a collision does occur, the impact is minimized, turning a harmful event into a controlled scenario with reduced consequences.
3Reliability
If capability information acquisition and priority determination system is implemented, then collision probability and impact are reduced, but the device complexity increases
Solution Approach 1:
The control device receives capability information from moving objects and uses this feedback to determine priority orders. This feedback mechanism allows the system to adaptively manage intersection passage based on actual object capabilities, improving reliability while keeping the control logic relatively simple through standardized information processing.
