Vehicle Seat Control System for Efficient Passenger Loading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle seat systems require manual adjustment for loading multiple passengers and objects, making it difficult to efficiently prepare the optical environment for loading, especially when the number of passengers and objects varies.
Innovation Solution
A control system for vehicle seats that includes seat actuators, a motion calculator, and a driving controller, which calculates and executes seat motions such as folding, reclining, or sliding based on passenger and object information input by the user, optimizing seat arrangements for efficient loading.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual seat adjustment is used for loading passengers and objects, then the system is simple and reliable, but the time required for adjusting multiple seats increases and productivity decreases
Solution Approach 1:
The motion calculator calculates and determines the optimal seat motions in advance based on passenger and object information before the actual loading process begins. This preliminary calculation enables the driving controller to execute pre-determined seat adjustments, significantly reducing the time required during the actual loading operation and improving overall productivity.
2Productivity
If automatic seat adjustment is implemented, then loading efficiency improves, but the device complexity increases due to additional actuators and control systems
Solution Approach 1:
The seat actuator is designed as a multi-functional device capable of performing multiple types of motions including folding, reclining, sliding, and rotating. This universal actuator can handle various seat adjustment requirements through a single device, reducing the need for multiple specialized actuators and simplifying the overall control system architecture while maintaining high loading efficiency.
3Adaptability or versatility
If multiple seat adjustments are performed for different passenger configurations, then comfort and space allocation are optimized, but the operation complexity increases
Solution Approach 1:
The motion calculator automatically receives passenger and object information, calculates the optimal seat configurations, and generates adjustment commands without requiring user intervention. The system serves itself by autonomously determining the best seat arrangements based on input data, eliminating the need for users to manually operate multiple seats while maintaining high adaptability to different passenger configurations.
4Loss of time
If seat motions are calculated in advance, then loading preparation time is reduced, but the calculation complexity and processing requirements increase
Solution Approach 1:
The motion calculator segments the complex calculation task by first matching passengers with appropriate seats based on passenger information, then calculating motions for each seat independently. This segmentation of the calculation process into discrete matching and motion calculation steps simplifies the overall processing complexity while enabling efficient advance preparation for loading operations.
