Lane-Structured Rule Control for Low-Latency Automated Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rule-based systems face challenges in efficiently navigating dynamic environments due to high computational costs and latency, particularly in applications like self-driving vehicles, stock trading, and medical diagnosis, where complex and unpredictable conditions require rapid responses and efficient resource management.
Innovation Solution
Implementing a lane-structured dynamic environment, where a controlled system navigates through discretized directional path segments (lanes) within an N-dimensional space, using rule-based systems to execute lane maneuvers in response to environmental changes, reducing the complexity of navigation and improving reaction times.

Engineering Contradiction Analysis
1Reliability
If traditional rule-based systems navigate dynamic environments without lane structuring, then they can handle complex environmental conditions, but computational overhead and latency increase significantly
Solution Approach 1:
The continuous dynamic environment is segmented into discrete directional path segments called lanes. The controlled system navigates by transitioning between these predefined lanes rather than computing continuous paths, reducing computational complexity and response latency while maintaining navigation reliability.
2Reliability
If traditional rule-based systems evaluate all possible actions in dynamic environments, then they can ensure comprehensive coverage of scenarios, but computational resources are excessively consumed
Solution Approach 1:
The action space is segmented into discrete lane maneuvers associated with each lane. Instead of evaluating all possible actions in the continuous environment, the system only evaluates maneuvers relevant to the current and adjacent lanes, significantly reducing computational resource consumption while maintaining comprehensive scenario coverage through the structured lane representation.
Solution Approach 2:
The system dynamically determines which lanes are relevant based on the current environmental state and controlled system position. This dynamic lane relevance assessment allows the system to focus computational resources only on evaluating maneuvers for currently relevant lanes, optimizing the balance between scenario coverage and resource consumption.

AI summary
Specifications are input, comprising: a plurality of lanes in an environment for a controlled system; a plurality of lane maneuvers associated with the plurality of lanes; a plurality of lane subconditions associated with the controlled system; and a rule set comprising a plurality of rules, wherein a rule in the rule set specifies a rule condition and a rule action to take when the rule condition is satisfied, wherein the rule condition comprises a corresponding set of lane subconditions, and wherein the rule action comprises a corresponding lane maneuver. The controlled system is automatically navigated dynamically, at least in part by: monitoring the plurality of lane subconditions; evaluating rule conditions associated with the plurality of rules in the rule set to determine one or more rules whose corresponding rule conditions has been met; and executing one or more lane maneuvers that correspond to the one or more determined rules.
