Automated Driving Controller Personalization via Dynamic Mode Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automated driving systems fail to reflect user preferences regarding control characteristics such as acceleration/deceleration and cornering, limiting personalized driving experiences.
Innovation Solution
A vehicle control system that includes a reception section for selecting from multiple driving modes with different control characteristics and an automated driving controller that adjusts speed and steering based on user preferences, allowing for transitions between manual and automated driving modes, and setting driving modes based on occupant-specific features.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If automated driving control is implemented with fixed control characteristics, then automation level is improved, but user preference adaptation deteriorates
Solution Approach 1:
The system dynamically switches between multiple driving modes (first driving mode, second driving mode, third driving mode) based on user selection, allowing control characteristics to adapt to user preferences while maintaining automated driving functionality. This resolves the contradiction by making the automated system flexible rather than fixed.
Solution Approach 2:
The system changes control parameters such as acceleration/deceleration thresholds and inter-vehicle distance thresholds depending on the selected driving mode. For example, the third driving mode has looser restrictions with smaller threshold values, while the second driving mode has tighter restrictions for energy efficiency, allowing the system to adapt to different user preferences.
2Adaptability or versatility
If multiple driving modes with different control characteristics are provided, then user preference adaptation is improved, but device complexity deteriorates
Solution Approach 1:
The automated driving controller is designed to handle multiple driving modes through a single unified system that selects and applies appropriate control characteristics based on the received driving mode signal. This multi-functional design provides diverse driving experiences without requiring separate control systems for each mode, thus managing complexity effectively.
3Use of energy by moving object
If stricter control restrictions are applied for energy efficiency, then energy efficiency is improved, but driving performance deteriorates
Solution Approach 1:
The system dynamically adjusts control restrictions based on the selected driving mode. The second driving mode applies stricter restrictions to improve energy efficiency, while the third driving mode applies looser restrictions to prioritize driving performance. Users can select the appropriate mode based on their current needs, resolving the contradiction between energy efficiency and performance.

AI summary
A vehicle control system includes: a reception section configured to receive a selection operation for one or more driving modes by an occupant of a vehicle from out of plural driving modes having different control characteristics related to acceleration/deceleration or cornering; and an automated driving controller configured to perform automated driving in which at least one of speed control and steering control of the vehicle is controlled automatically based on the driving mode received as the selection operation by the reception section.
