Vehicle Driving State Control Device with Driver Preference Settings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional driving assist devices for low-skilled drivers forcibly apply driving assists without considering the driver's intention, leading to dissatisfaction and a lack of enjoyment during driving.
Innovation Solution
A vehicle control device that includes a state control unit and a driving control unit, allowing for multiple travel states and assist states, where the driver's preference for manual driving is respected, suppressing transitions to higher assist states when the driver prefers manual control, enabling accurate reflection of driving intention and minimizing awareness of state transitions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If driving assist is forcibly applied to low-skilled drivers, then driving safety is improved, but driver satisfaction and enjoyment deteriorate
Solution Approach 1:
The system dynamically adjusts the level of driving assist based on the detected travel state. When a sporty driving state is detected (indicating driver preference for manual control), the system reduces or suppresses driving assist interventions. When a normal driving state is detected, the system provides standard driving assist. This dynamic adaptation resolves the contradiction by making the assist level flexible rather than fixed, thereby maintaining safety while respecting driver preference and satisfaction.
2Adaptability or versatility
If driving assist level is increased for low-skilled drivers, then driving assistance effectiveness is improved, but driver autonomy and control deteriorate
Solution Approach 1:
The system changes the parameter of assist level based on the detected travel state. By monitoring driving behavior patterns and identifying sporty driving states, the system adjusts the assist parameter dynamically. This allows the system to provide high assistance effectiveness when needed (normal driving state) while preserving driver autonomy when the driver prefers manual control (sporty driving state), thus resolving the contradiction between assistance effectiveness and driver autonomy.
3Adaptability or versatility
If multiple assist states are provided, then driving assist adaptability is improved, but system complexity increases
Solution Approach 1:
The system segments the driving context into distinct travel states (normal driving state and sporty driving state) based on detected driving behavior patterns. By categorizing driving contexts into discrete states, the system can apply different assist levels appropriately without requiring continuous complex analysis. This segmentation approach provides high adaptability across different driving scenarios while keeping the system relatively simple through clear state classification and transition rules.

AI summary
A vehicle control device is equipped with a state control unit adapted to perform a state transition control in which there are combined plural types of travel states in accordance with a travel control mode, and plural types of assist states in accordance with a driving assist mode. Under a sports mode (second travel state) in which a preference of the driver for manual driving is strong, as compared with a normal travel mode (first travel state), the state control unit suppresses a transition from a manual driving state (first assist state) to a normal automated driving state (second assist state) in which a level of driving assistance is high.
