Vehicle Control Apparatus for Adaptive Automated Driving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In automated vehicle driving, existing systems fail to adapt the traveling mode in response to changes in the occupant's state, potentially leading to inappropriate driving conditions.
Innovation Solution
A vehicle control apparatus equipped with a state detection unit to monitor the occupant's state and a control unit that adjusts the automated driving mode accordingly, allowing for switching between modes such as time priority and stable modes based on the occupant's status, such as sleeping or the presence of children.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If automated driving uses a fixed traveling mode, then the control system is simple and reliable, but it cannot adapt to changes in occupant state
Solution Approach 1:
The traveling mode is changed from fixed to dynamic and adjustable. The control unit switches between first traveling mode (when occupant is awake) and second traveling mode (when occupant is sleeping) based on real-time detection of occupant state, making the system adaptive to changing conditions
Solution Approach 2:
The state detection unit continuously monitors occupant state and provides feedback to the control unit. This feedback loop enables the system to automatically adjust the traveling mode according to the detected occupant state, resolving the contradiction between adaptability and system complexity
2Productivity
If automated driving prioritizes speed to reduce travel time, then productivity increases, but it causes excessive vehicle oscillation that may wake sleeping occupants
Solution Approach 1:
Different traveling modes are applied based on local conditions (occupant state). When the occupant is sleeping, the system uses a mode that prioritizes stability over speed, reducing vehicle oscillation. When the occupant is awake, the system can use faster traveling modes, thus adapting the driving characteristics to the specific situation
Solution Approach 2:
The control unit changes driving parameters (speed, acceleration, deceleration) based on occupant state. In the second traveling mode for sleeping occupants, parameters are adjusted to minimize oscillation and prevent wake-up, while in the first traveling mode for awake occupants, parameters can be optimized for faster travel
