Vehicle Drive Assist Path Control for Falling Aerial Objects
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Related-art drive assist apparatuses struggle to determine whether to avoid collisions with objects in the air that do not hinder vehicle travel, leading to unnecessary obstacle avoidance controls and driver discomfort.
Innovation Solution
A vehicle drive assist apparatus that includes a surrounding environment recognition device, a traveling control unit, and a steering control unit to identify and determine if aerial objects pose a threat to vehicle travel, estimating their falling points and adjusting the vehicle's path accordingly to avoid collisions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the drive assist apparatus executes obstacle avoidance control for all recognized aerial objects, then collision avoidance with potential objects is improved, but unnecessary control actions increase causing driver discomfort
Solution Approach 1:
The system changes the parameter of object classification by analyzing multiple features (size, shape, movement pattern, altitude) to distinguish between harmful aerial objects requiring avoidance and harmless ones allowing normal travel, thereby resolving the contradiction between comprehensive safety and driver comfort
Solution Approach 2:
The system segments aerial objects into different categories (harmful vs. harmless) based on their characteristics, applying different control strategies to each segment - obstacle avoidance control for harmful objects and normal travel for harmless objects, thus eliminating unnecessary control actions while maintaining safety
2Loss of information
If the drive assist apparatus recognizes all types of objects including airborne objects, then comprehensive environment awareness is improved, but false positive obstacle detection increases
Solution Approach 1:
The system uses multiple recognition parameters (object size, shape characteristics, movement patterns, altitude from road surface) to accurately distinguish between different types of aerial objects, improving identification precision while maintaining comprehensive environment awareness
Solution Approach 2:
The system introduces an intermediate classification process that acts as a mediator between object detection and obstacle avoidance control, using feature analysis to filter out false positives before triggering avoidance maneuvers

AI summary
A vehicle drive assist apparatus for avoiding collision of a vehicle with a recognized object recognizes a surrounding environment around the vehicle; acquires feature information of a three-dimensional object in the surrounding environment; sets a traveling path of the vehicle based on the surrounding environment; recognizes an aerial object based on the feature information; identify a type of the aerial object based on the feature information; determines whether the aerial object has a possibility of hindering traveling of the vehicle; performs steering control based on a control signal; continues normal traveling control when the aerial object does not have the hindrance possibility; estimates a falling point of the aerial object when the aerial object has the hindrance possibility; when the falling point is on the traveling path of the vehicle, sets a new traveling path to steer around the falling point and executes traveling control along the new traveling path.
