Vehicle Driving Control System Adapted to Current Trip Preferences
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing driving control systems for vehicles that switch between manual and automated driving often apply outdated driving characteristics learned during previous manual driving sessions, leading to automated driving that does not align with the occupant's current preferences.
Innovation Solution
A driving control method and apparatus that compares the occupant's current manual driving characteristics with stored reference characteristics and adjusts automated driving settings to match the desired characteristics for the present trip, using data from the vehicle's running state and environmental conditions to ensure alignment with the occupant's intentions.

Engineering Contradiction Analysis
1Extent of automation
If the driving control apparatus uses driving characteristics learnt during past manual driving for automated driving, then automated driving can be executed with learned driving patterns, but the automated driving may not align with the occupant's current desired driving characteristics
Solution Approach 1:
The system dynamically switches between using past learned driving characteristics and current manual driving characteristics based on the automated driving execution flag. When automated driving is executed, the system determines whether to apply historically learned characteristics or real-time manually operated characteristics, making the system adaptable to the occupant's current intentions while maintaining automated driving functionality
Solution Approach 2:
The system changes the parameter of driving characteristics being applied by setting different values for the automated driving execution flag. When the flag indicates automated driving execution, the system switches from using past learned characteristics to using current manual driving characteristics, thereby adapting to the occupant's present preferences
2Adaptability or versatility
If the driving control apparatus continuously learns and updates driving characteristics during manual driving, then the system can adapt to changing occupant preferences, but there is a risk of using outdated or inconsistent characteristics during automated driving
Solution Approach 1:
The system performs preliminary determination of whether to execute automated driving before applying driving characteristics. By setting the automated driving execution flag in advance and determining characteristic application based on this flag, the system ensures consistent and reliable characteristic application rather than using potentially outdated continuously updated characteristics

AI summary
A driving control method compares, in a vehicle capable of switching manual driving to run the vehicle according to driving operations of an occupant and automated driving to automatically run the vehicle from one to another, occupant's driving characteristics of manual driving in a present trip of the vehicle with reference driving characteristics stored in advance, and if a predetermined deviation occurs between the occupant's driving characteristics of manual driving in the present trip and the reference driving characteristics, sets driving characteristics applied to the automated driving according to the occupant's driving characteristics of manual driving in the present trip.
