Inter-Vehicle Collision Risk Detection With Automatic Vehicle Type Setting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing safe driving assistance technologies for large vehicles in severe environments like mines face challenges with initial device settings, device failures, and communication issues, leading to inefficiencies and user-unfriendliness, particularly when vehicles are not under fleet management control.
Innovation Solution
A safe operation assistance device that determines collision risk independently of vehicle type and environment, using onboard units with inter-vehicle communication and automatic unique information setting, allowing for continuous operation even without fleet management center connectivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If collision risk determination considers vehicle type differences, then collision prevention accuracy is improved, but initial setting time and effort increase
Solution Approach 1:
The determination device automatically acquires vehicle type information from the operation management system without requiring manual input. The system performs self-configuration by receiving vehicle type data through the communication interface, eliminating the need for operators to manually set vehicle type parameters during initial installation.
Solution Approach 2:
The operation management system serves as an intermediary that stores and provides vehicle type information. Instead of direct manual input to the determination device, the vehicle type data is transmitted through the communication interface from the operation management system, automating the information acquisition process.
2Adaptability or versatility
If information transmission goes through fleet management center, then centralized control is achieved, but information updating time increases
Solution Approach 1:
The information transmission path is segmented into two modes: centralized transmission through the fleet management center for controlled environments, and direct peer-to-peer transmission between determination devices for rapid updates. This segmentation allows the system to select the appropriate transmission path based on operational requirements.
Solution Approach 2:
The system dynamically switches between centralized and direct communication modes. When the determination device can directly acquire vehicle type information from other determination devices, it does so for faster updates; otherwise, it falls back to the fleet management center for centralized control.
3Adaptability or versatility
If fleet management center communication is required, then centralized monitoring is improved, but system reliability in poor communication areas decreases
Solution Approach 1:
The determination device extracts the essential function of vehicle type information acquisition from the centralized fleet management center and implements it locally through direct communication with other determination devices. This extraction allows the system to operate independently in areas with poor communication infrastructure.
Solution Approach 2:
The determination device is pre-configured with the capability to acquire vehicle type information through multiple channels. Before relying on fleet management center communication, the system can directly obtain information from neighboring vehicles, ensuring continuous operation even when centralized communication is unavailable.
4Productivity
If operation management system control is mandatory, then fleet management efficiency is improved, but adaptability to uncontrolled vehicles decreases
Solution Approach 1:
The determination device is designed with universal communication capabilities that work with both fleet management system-controlled vehicles and independent vehicles. The device can acquire vehicle type information from either the operation management system through the communication interface or directly from other determination devices, making it compatible with all vehicle types regardless of their control status.
