Solution Overview
Problem
Existing routing and navigation systems face challenges due to limited wireless network coverage and bandwidth, as well as increased computing requirements for autonomous vehicles, leading to inefficiencies in traffic management and vehicle operation.
Innovation Solution
The implementation of ad hoc communication and data sharing networks, such as vehicle-to-vehicle (V2V) networks, which allow vehicles to share data and resources wirelessly, reducing the reliance on central cloud networks and optimizing processing and communication resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If vehicles rely on central cloud networks for routing and navigation, then comprehensive data processing can be achieved, but wireless network coverage and bandwidth limitations cause traffic congestion and inefficiency
Solution Approach 1:
The patent segments the centralized cloud network into distributed ad hoc networks among vehicles. Each vehicle maintains local routing information and shares data directly with nearby vehicles, dividing the monolithic network into smaller autonomous segments that operate independently, thereby reducing congestion on central network infrastructure.
Solution Approach 2:
The patent merges multiple vehicles into ad hoc network clusters where they collectively share routing data and computational resources. By combining the networking capabilities of individual vehicles into a distributed mesh network, the system achieves enhanced bandwidth and reduced dependency on central cloud infrastructure.
2Reliability
If autonomous vehicles increase computing capabilities for advanced processing, then better autonomous driving performance is achieved, but processing requirements and energy consumption increase
Solution Approach 1:
The patent enables vehicles to serve themselves by maintaining local routing tables and making autonomous routing decisions based on shared ad hoc network data. Each vehicle independently processes routing information and makes navigation decisions without requiring intensive cloud-based computing, reducing onboard processing energy consumption while maintaining autonomous driving capabilities.
3Quantity of substance
If ad hoc networks are used for data sharing, then network coverage and bandwidth are enhanced, but network complexity and management difficulty increase
Solution Approach 1:
The patent implements universal routing protocols that enable vehicles to simultaneously participate in ad hoc networking, routing data sharing, and autonomous navigation. The same communication infrastructure serves multiple functions including vehicle-to-vehicle data exchange, routing information propagation, and collaborative awareness, reducing the need for separate specialized systems.
