Driver Assistance Parameter Adaptation From Occupant Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing driver assistance systems in motor vehicles often fail to adapt operating parameters to the comfort level of vehicle occupants, leading to discomfort and requiring manual adjustments, especially as occupant preferences can change throughout the day or with varying passenger loads.
Innovation Solution
A method and system that adjust operating parameters such as speed, acceleration, and distance by monitoring vehicle occupants' biometric data and activities during driving maneuvers, allowing real-time adaptation of driving profiles to ensure occupant comfort through a direct link between occupant feedback and control systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If driver assistance systems use preset parameters for driving maneuvers, then the system operation is simple and reliable, but the occupant comfort deteriorates when parameters do not match personal preferences
Solution Approach 1:
The system monitors occupant reactions during driving maneuvers (such as hand movements toward steering wheel, body position changes, or explicit feedback) and uses this feedback to automatically adjust operating parameters like acceleration, braking force, and cornering speed. This creates a closed-loop system that continuously adapts to individual occupant preferences while maintaining reliable automated operation.
Solution Approach 2:
The driver assistance system performs self-adjustment of its operating parameters without requiring manual intervention from the occupant. The system autonomously learns and adapts to preferred settings by analyzing occupant behavior patterns and automatically modifying acceleration rates, braking characteristics, and maneuver smoothness to match individual preferences.
2Adaptability or versatility
If multiple driver assistance systems are implemented in the vehicle, then the functional capability is improved, but the complexity of manual parameter adjustment increases
Solution Approach 1:
The patent integrates multiple driver assistance systems (adaptive cruise control, lane keeping assist, autonomous emergency braking, etc.) under a unified parameter adaptation framework. A single set of learned occupant preferences is applied across all assistance systems, coordinating their operating parameters to work together harmoniously rather than requiring separate adjustments for each system.
Solution Approach 2:
The parameter adaptation mechanism serves as a universal control layer that manages multiple different driver assistance systems simultaneously. The system learns general occupant preferences for comfort and control style that can be universally applied across various driving scenarios and assistance functions, reducing the overall complexity of system interaction.
3Extent of automation
If the vehicle operates in autonomous mode with fixed parameters, then the automation level is high, but the occupant comfort deteriorates when parameters do not match current personal conditions
Solution Approach 1:
The system transitions from static, fixed parameters to dynamic, adaptive parameters that change in real-time based on monitored occupant conditions. Operating parameters such as acceleration smoothness, braking gentleness, and cornering speed are continuously adjusted during autonomous operation to match the occupant's current state, whether they prefer sporty or comfortable driving characteristics on different days.
