Autonomous Driving Control Apparatus Obstacle Classification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing autonomous driving control technologies often cause unnecessary steering maneuvers when encountering obstacles that can be safely passed over, leading to discomfort for occupants and disruptions in surrounding traffic.
Innovation Solution
An autonomous driving control apparatus that determines whether an obstacle is 'passage acceptable' and assesses traffic conditions, including oncoming vehicles and available space, to decide between steering around or passing over the obstacle, thereby minimizing influence on occupants and surrounding traffic.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the autonomous driving control always steers to avoid obstacles on the planned driving path, then collision avoidance is improved, but unnecessary steering maneuvers occur when obstacles can be safely passed over, causing discomfort to occupants and disruptions in surrounding traffic
Solution Approach 1:
The system changes the control parameter from binary (steer or not) to conditional (steer only when necessary). It introduces new parameters including obstacle type classification (passage acceptable vs. unacceptable), traffic condition assessment (oncoming vehicles, available space), and contact risk prediction. These parameter changes enable nuanced decision-making that balances collision avoidance with occupant comfort by allowing passage over certain obstacles like puddles while maintaining steering for hazardous obstacles.
2Reliability
If the autonomous driving control always steers to avoid obstacles on the planned driving path, then collision avoidance is improved, but traffic flow disruption increases due to unnecessary steering maneuvers
Solution Approach 1:
The system introduces traffic condition parameters including detection of oncoming vehicles and calculation of available space for steering maneuvers. By adding these parameters to the decision framework, the system can predict when steering would disrupt traffic flow and avoid such maneuvers when the obstacle can be safely passed over, thereby maintaining productivity while ensuring safety through conditional rather than universal steering responses.
3Reliability
If the autonomous driving control steers to avoid obstacles, then contact with obstacles is reduced, but the system complexity increases due to additional traffic condition determination requirements
Solution Approach 1:
The control instruction section serves multiple functions: it determines obstacle characteristics, assesses traffic conditions, predicts contact risk, and generates appropriate control instructions all in one integrated component. This multi-functionality approach consolidates what could be separate complex subsystems into a single coordinated unit, managing device complexity while maintaining comprehensive obstacle avoidance capabilities through unified control logic.

AI summary
An autonomous driving control apparatus installable in a vehicle includes a path determining section, an obstacle determining section that determines whether an obstacle on the planned driving path is a passage acceptable obstacle or a passage unacceptable obstacle, the passage acceptable obstacle being previously set as an obstacle that the vehicle is allowed to come into contact with while passing, the passage unacceptable obstacle being previously set as an obstacle that the vehicle is not allowed to come into contact with while passing, and a control instructing section that gives an instruction of control to a maneuver controller to perform at least one of controlling a speed of the vehicle and controlling a steering of the vehicle to control a maneuver of the vehicle. If the obstacle is determined to be the passage acceptable obstacle, the control instructing section gives an instruction of the control to pass over the obstacle.
