Vehicle Route Guidance Deviation Zone Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle route guidance systems rely heavily on historical trajectory data, which is often not significant in current driving situations and can be unclear when multiple trajectories differ, limiting their use for safe and comfortable routing.
Innovation Solution
A method that provides a route stipulation for a vehicle by detecting and analyzing trajectories from other vehicles, determining a deviation zone based on these trajectories, and using this information to improve vehicle guidance, combining it with current data for transverse and longitudinal control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If trajectory stipulation is based on historical data from multiple vehicles, then route guidance is provided, but the significance is reduced when trajectories differ and evaluation becomes unclear
Solution Approach 1:
The patent introduces a deviation zone as an intermediary concept between the trajectory stipulation and individual vehicle trajectories. This deviation zone serves as a mediator that accommodates variations in historical trajectories while maintaining a clear evaluation framework. By defining acceptable deviation boundaries, the system can evaluate multiple trajectories without losing clarity, thus resolving the contradiction between reliability and information loss.
2Loss of information
If trajectory stipulation is used for vehicle guidance, then route information is provided, but safety and comfort are compromised when trajectories differ significantly
Solution Approach 1:
The patent applies local quality by defining a deviation zone with specific boundaries around the trajectory stipulation. Instead of treating all trajectories uniformly, the system locally evaluates each trajectory's deviation from the stipulation. This allows the system to maintain route information availability while ensuring safety and comfort by identifying and filtering out trajectories that exceed acceptable deviation thresholds in critical areas.
3Adaptability or versatility
If multiple detected trajectories are analyzed, then route options are available, but computing effort increases
Solution Approach 1:
The patent extracts only the essential information needed for route evaluation by defining a deviation zone around the trajectory stipulation. Instead of analyzing every detail of multiple trajectories, the system extracts the key deviation metrics and compares them against the predefined zone boundaries. This extraction approach maintains route option availability while significantly reducing computing effort by focusing only on relevant deviation parameters.
