Vehicle Maneuver Request Coordination for Route Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current traffic management systems fail to optimize route guidance for individual vehicles, increasing travel time due to the complexity of calculating vehicle-specific goals amidst a large number of road users.
Innovation Solution
A method where a control device of a first vehicle determines the need for communication based on measurement data and generates a header with static and dynamic information to send a maneuver request to nearby vehicles, allowing for coordinated maneuvers to optimize route progression, using dedicated communication standards like DSRC or IEEE 802.11p, and secure communication to establish rights of way and coordinate actions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If holistic optimization of route guidance is implemented considering all road users, then route optimization quality improves, but system complexity increases exponentially
Solution Approach 1:
The patent segments the traffic optimization problem into individual vehicle-level decisions. Instead of calculating holistic optimization for all road users simultaneously, each vehicle independently evaluates maneuver requests from nearby vehicles and makes local decisions. This divides the exponentially complex global problem into manageable local decisions, maintaining route optimization quality while avoiding exponential system complexity.
2Loss of time
If individual vehicle routing is optimized using navigation software, then travel time for individual routes improves, but overall traffic flow optimization deteriorates
Solution Approach 1:
The patent merges individual vehicle routing optimization with overall traffic flow optimization by enabling direct communication between vehicles. Each vehicle's navigation software independently optimizes its route, while simultaneously exchanging maneuver requests and responses with other vehicles. This combination allows individual travel time reduction while achieving collective traffic flow efficiency through coordinated maneuvers like platooning and cooperative lane changes.
3Adaptability or versatility
If maneuver requests are broadcast to all nearby vehicles, then coordination opportunities increase, but communication overhead increases
Solution Approach 1:
The patent applies local quality by making maneuver requests highly specific to local conditions. Each request includes precise criteria about the requesting vehicle's state, desired maneuver, and validity conditions. Receiving vehicles only process requests that match their local situation and capabilities, filtering out irrelevant communications. This maintains high coordination capability while minimizing communication overhead by ensuring each vehicle only processes relevant messages.
