Vehicle Path Control Using Branching-Area Behavior Prediction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing driver assistance and autonomous driving systems fail to account for potential changes in the driving route of detected objects, leading to increased computational resources and decreased driving comfort, especially in areas like roundabouts and highway approaches.
Innovation Solution
A vehicle travelling control apparatus that includes a localization unit, area prediction unit, object detection unit, and object behavior prediction unit, which determines potential meeting areas and adapts the vehicle's path based on predicted object behavior using map information and sensor data, optimizing computational effort by switching between normal and detailed prediction modes.

Engineering Contradiction Analysis
1Reliability
If detailed analysis of the behavior (manoeuvres) of the detected object is performed, then collision avoidance capability is improved, but computational resources required increase
Solution Approach 1:
The patent divides the prediction process into two distinct modes: normal prediction mode for objects outside the branching area, and detailed prediction mode for objects within the branching area. This segmentation allows the system to apply computational effort selectively - only performing detailed behavior analysis when necessary (when an object is in the branching area), while using simpler prediction for other cases, thus resolving the contradiction between collision avoidance capability and computational resource requirements
Solution Approach 2:
The system applies detailed prediction mode only partially - specifically when a detected object enters the branching area. For all other situations, normal prediction mode suffices. This partial application of detailed analysis ensures high collision avoidance capability when needed while avoiding excessive computational resource consumption during routine operations
2Ease of operation
If potential changing manoeuvres of the detected object are taken into account, then driving comfort is improved, but computational resources required increase
Solution Approach 1:
The patent segments the monitoring space into a branching area (where detailed prediction is applied) and other areas (where normal prediction suffices). This allows the system to account for potential changing maneuvers only when relevant (in the branching area), improving driving comfort through adaptive behavior prediction without continuously consuming high computational resources
Solution Approach 2:
Detailed behavior prediction is applied only partially - when objects are within the branching area where maneuver changes are most relevant to driving comfort. This selective application provides enhanced driving comfort prediction exactly where needed while avoiding unnecessary computational overhead in other situations
