Autonomous Driving Pattern Recognition for Human-Like Maneuvers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Automated driving systems often fail to replicate safe driver behaviors, leading to occupant discomfort due to aggressive navigation strategies, necessitating improved communication and adaptation of driving characteristics to enhance comfort and trust.
Innovation Solution
A system that recognizes patterns in driver behavior, environmental cues, and vehicle status, integrating them into a database to mimic safe driving maneuvers, such as lane changes and braking, to perform pattern responses in autonomous mode, while displaying decision transparency to the driver.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If automated driving systems use aggressive navigation strategies to effectively navigate roadways, then navigation efficiency is improved, but occupant comfort deteriorates
Solution Approach 1:
The system changes the parameters of driving behavior by learning from human driver patterns. Instead of using fixed aggressive navigation parameters, the system adapts parameters such as lane change timing, braking intensity, and acceleration rates to match human driver characteristics, thereby maintaining navigation efficiency while reducing occupant discomfort
Solution Approach 2:
The system copies safe driving behaviors from human drivers by capturing and analyzing their driving patterns. The pattern recognition module identifies and replicates human driver responses to various road situations, allowing the automated vehicle to navigate efficiently while providing the comfort and predictability of human-like driving behavior
2Object-affected harmful factors
If automated driving systems adopt human-like driving patterns to increase occupant comfort, then occupant comfort is improved, but system complexity increases
Solution Approach 1:
The system performs self-learning and self-adaptation by automatically capturing driver behavior patterns and integrating them into its control algorithms. The pattern recognition module continuously monitors driver actions and autonomously updates the driving behavior database, eliminating the need for complex manual programming of human-like behaviors
Solution Approach 2:
The system implements feedback loops where driver responses to automated vehicle actions are continuously monitored and used to refine future behavior. The pattern recognition module analyzes driver corrections and adjustments, feeding this information back into the system to improve subsequent driving patterns, thereby achieving human-like comfort through adaptive learning rather than fixed complexity

AI summary
A system includes a pattern recognizing module that identifies a pattern based on at least one of: (i) a movement of a driver of a vehicle, (ii) an object in front of the vehicle, (iii) a status of the vehicle, and (iv) an action of the vehicle. The pattern corresponds to a pattern response. A safety module compares the pattern response to a safe maneuver database. The pattern response is classified as safe in response to the pattern response matching at least one safe pattern response of the safe maneuver database. A pattern integration module integrates the pattern and the pattern response into a pattern database in response to the pattern response matching the at least one safe pattern response of the safe maneuver database. A vehicle control module performs the pattern response in response to the pattern recognizing module identifying the pattern.
