Active Suspension Attitude Control for Injured Occupant Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle control systems for active suspensions do not consider the physical condition or injury status of occupants, leading to inadequate attitude control during vehicle movements.
Innovation Solution
A vehicle control device that includes a state detection device to monitor vehicle acceleration, an occupant information acquisition device for inputting physical condition or injury status, and a controller to adjust the active suspension's control variables based on this information, thereby performing attitude control tailored to the occupant's condition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional active suspension attitude control is applied without considering occupant condition, then general vibration reduction is achieved, but comfort and safety are insufficient for occupants with abnormal physical conditions
Solution Approach 1:
The control system dynamically adjusts the controlled variable based on real-time occupant condition information. When an abnormal condition is detected, the system switches from standard control to corrected control parameters, making the suspension adaptable to different occupant states rather than using fixed control characteristics
Solution Approach 2:
The system changes the controlled variable parameter of the active suspension based on occupant condition. When abnormal conditions are detected, the controller modifies the control parameters to correct the attitude control, thereby adapting the suspension characteristics to match the occupant's physical state
2Reliability
If the controlled variable is corrected based on occupant information, then attitude control according to physical condition is achieved, but system complexity increases
Solution Approach 1:
The controller integrates multiple functions: it monitors occupant condition through the occupant information acquisition device, determines abnormal states, and automatically adjusts control parameters. This multi-functional integration avoids the need for separate complex systems for each function
Solution Approach 2:
The system establishes a feedback loop where occupant condition information is continuously acquired, processed by the controller, and used to adjust the controlled variable. This closed-loop feedback mechanism enables automatic adaptation without requiring complex manual intervention systems
