Coordinated Lane Change via Network Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current self-driving systems face challenges in ensuring safe and coordinated lane changes, as they rely solely on vehicle sensors, which can lead to collisions due to lack of communication with other vehicles and are affected by environmental factors like weather, resulting in reduced traffic safety and efficiency.
Innovation Solution
A method and apparatus for self-driving vehicles that utilize a network device for information exchange, allowing vehicles to coordinate lane changes by sharing real-time data on speed and location, adjusting vehicle speeds if necessary, and receiving lane change indications to prevent collisions and optimize traffic flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If self-driving systems rely solely on vehicle sensors for lane change decisions, then the system can operate independently without network communication, but collision risk increases due to lack of coordination with other vehicles
Solution Approach 1:
The network device serves as an intermediary between vehicles, enabling information exchange about lane change intentions and real-time positions. The first vehicle sends lane change request information to the network device, which then coordinates with the second vehicle to ensure safe lane changes, preventing collisions through centralized information management.
2Reliability
If vehicles exchange real-time information through a network device for coordinated lane changes, then traffic safety and order improve, but system complexity and communication requirements increase
Solution Approach 1:
The network device performs multiple functions: receiving lane change requests, tracking real-time vehicle positions, coordinating between vehicles, and sending lane change indications. This multi-functional approach consolidates complex operations into a single centralized system, managing complexity through functional integration.
3Productivity
If the network device coordinates lane changes by processing real-time information from multiple vehicles, then lane change efficiency and traffic flow optimization improve, but information processing time and computational load increase
Solution Approach 1:
The first vehicle sends a lane change request information to the network device in advance, allowing the network device to pre-coordinate with the second vehicle before the actual lane change occurs. This preliminary action enables proactive traffic flow management and reduces last-minute processing delays.
