Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle fleet cooperative control systems face issues such as time delays, data packet loss, and out-of-order transmissions leading to vehicle instability and frequent acceleration/deceleration, which can result in accidents, especially when interacting with other road participants.
Innovation Solution
An intelligent cooperative control system that integrates environment perception, vehicle status monitoring, and communication modules to fuse information, perform safety verification, and execute either vehicle motion or safety control instructions based on risk assessment, ensuring vehicle safety and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If direct vehicle-to-vehicle communication is used for fleet cooperative control, then communication efficiency and response speed are improved, but communication reliability deteriorates due to time delay, data packet loss, and out-of-order transmission
Solution Approach 1:
The patent introduces a safety verification module as an intermediary between the cooperative control module and execution module. This mediator receives control instructions, verifies their safety against pre-established safety rules and real-time environmental data, and only permits execution of safe instructions. This resolves the contradiction by maintaining fast direct communication while adding a safety layer that filters out unreliable or dangerous instructions.
Solution Approach 2:
The system performs preliminary safety verification of control instructions before they are executed. By pre-establishing safety rules, spatial-temporal safety distances, and verification mechanisms, the system proactively identifies and blocks potentially dangerous instructions before they can cause harm. This preliminary action ensures communication reliability without sacrificing response speed.
2Productivity
If cooperative control instructions are executed directly without verification, then fleet coordination efficiency is improved, but safety deteriorates due to accumulated following errors and potential accidents
Solution Approach 1:
The safety verification module continuously monitors control instructions against real-time environmental perception data, vehicle status information, and pre-established safety rules. This feedback mechanism compares intended actions with safe operating boundaries and blocks instructions that would violate safety constraints. The system maintains high coordination efficiency by only blocking genuinely dangerous instructions while permitting safe ones to execute.
Solution Approach 2:
The system applies preliminary anti-action by pre-defining safety rules, spatial-temporal safety distances, and verification criteria before cooperative control operations begin. These pre-established constraints act as preventive measures that automatically counteract potentially harmful control instructions before they can cause accumulated errors or accidents, thereby protecting against harmful factors while maintaining coordination efficiency.
3Reliability
If safety verification module is added to verify control instructions, then safety is improved, but system complexity increases
Solution Approach 1:
The patent segments the control system into distinct functional modules: environment perception module, vehicle status monitoring module, cooperative control module, safety verification module, and execution module. Each module has a specific responsibility, with the safety verification module acting as a dedicated safety layer. This segmentation improves safety through specialized verification while managing complexity by localizing safety functions to a dedicated module rather than distributing complexity throughout the entire system.
