Coordinated Driving Maneuver Coordination via V2X
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle-to-vehicle (V2V) communication systems lack effective coordination for coordinated driving scenarios, particularly when obstacles emerge after a proposed driving maneuver is initiated, leading to potential safety hazards and inefficiencies.
Innovation Solution
A system that includes a vehicle communication system receiving proposed driving maneuvers from a tractor vehicle, allowing responses from a trailer vehicle, and utilizing a route generation module to generate routes based on acceptance or decline, with the ability to detect obstacles and determine alternative routes or delayed implementations to ensure safe and efficient driving.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the tractor vehicle executes a driving maneuver based on current information, then the driving efficiency is improved, but safety deteriorates when obstacles emerge after the maneuver is initiated
Solution Approach 1:
The system performs preliminary actions by having the tractor vehicle communicate its intended driving maneuver to the trailer vehicle before the maneuver is executed. This allows the trailer vehicle to prepare for the maneuver in advance, and enables obstacle detection and alternative route planning before the maneuver begins, thus maintaining safety while preserving driving efficiency.
Solution Approach 2:
The system implements continuous feedback loops where the trailer vehicle detects obstacles, communicates them back to the tractor vehicle, and receives updated maneuver instructions. This real-time feedback enables the system to adjust to emerging obstacles while maintaining coordinated driving, resolving the contradiction between executing maneuvers efficiently and ensuring safety.
2Reliability
If the trailer vehicle autonomously detects obstacles and requests alternative routes, then safety is improved, but the complexity of coordination increases
Solution Approach 1:
The system segments the coordinated driving function into distinct modular components: the tractor vehicle handles maneuver planning and communication, while the trailer vehicle handles obstacle detection and alternative route requests. This segmentation allows each vehicle to perform its specialized function independently, improving safety through autonomous obstacle detection while managing coordination complexity through clear division of responsibilities.
Solution Approach 2:
The trailer vehicle performs self-service by autonomously detecting obstacles, determining their impact on the route, and requesting alternative routes without requiring constant human intervention. This self-service capability improves safety through continuous autonomous monitoring while the standardized communication protocol keeps coordination complexity manageable.
3Reliability
If real-time obstacle detection and alternative route planning are implemented, then safety is improved, but the response time and driving efficiency may deteriorate
Solution Approach 1:
The system performs preliminary obstacle detection and alternative route planning before the tractor vehicle executes its driving maneuver. By having the trailer vehicle detect obstacles in advance and pre-plan alternative routes, the system ensures safety is maintained while minimizing response time, as the alternative route is ready for immediate execution when needed.
Solution Approach 2:
The system implements dynamic response strategies where the level of obstacle detection and route planning activity adjusts based on the driving context. When the tractor vehicle is executing a maneuver, the system dynamically activates obstacle detection and alternative route planning, ensuring safety is improved at critical moments while minimizing unnecessary processing during stable driving phases, thus reducing overall response time.

AI summary
According to one or more aspects, a system for coordinated driving may include a vehicle communication system receiving a proposed driving maneuver from a tractor vehicle, an input device receiving a response to the proposed driving maneuver from an occupant of a trailer vehicle, and a route generation module generating a route corresponding to the proposed driving maneuver based on the response to the proposed driving maneuver. The tractor vehicle may be engaged in segment-by-segment coordinated driving with the trailer vehicle utilizing a cooperative adaptive cruise control (CACC) module.
