Distributed Driving Resource Allocation for Lower-Power CAV Sensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Connected and Automated Vehicles (CAVs) rely on expensive and complex onboard systems, consuming large amounts of power for sensing and vehicle control, which limits their driving range and resource availability for other functions.
Innovation Solution
A Device Allocation System (DAS) is introduced to allocate, distribute, and arrange resources among Intelligent Roadside Toolbox (IRT) and CAV devices, optimizing objectives such as reliability, intelligence, efficiency, and resilience of the Distributed Driving System (DDS).
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If expensive and complex onboard systems are implemented in CAVs, then sensing and vehicle control capabilities are improved, but power consumption increases and driving range is limited
Solution Approach 1:
The patent merges sensing and control functions between CAV onboard systems and IRT roadside infrastructure. The IRT provides supplemental sensing capabilities and vehicle control functions, allowing the CAV to rely partially on external infrastructure rather than carrying all sensing and control equipment onboard, thereby reducing power consumption while maintaining reliability
Solution Approach 2:
The IRT infrastructure serves multiple vehicles simultaneously, providing universal sensing and control services to multiple CAVs. This multi-functional approach allows individual CAVs to reduce their onboard system complexity and power consumption while still accessing comprehensive sensing and control capabilities through the shared IRT infrastructure
2Extent of automation
If extensive onboard sensing systems are used, then automated driving functions are improved, but resource availability for other CAV functions is reduced
Solution Approach 1:
The system combines onboard CAV sensing resources with IRT roadside sensing resources to provide comprehensive automated driving functions. By merging these resources, the CAV can maintain high automation capabilities while using fewer onboard sensors, thereby preserving resources for other vehicle functions
Solution Approach 2:
The IRT infrastructure acts as an intermediary that provides sensing and control services to CAVs. Instead of each CAV carrying extensive onboard sensing systems, the IRT mediates by providing supplemental sensing data and control functions, reducing the resource burden on individual vehicles while maintaining automation performance
