Vehicle Seat Control Unit Error Detection and Mode Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle seating systems often require manual operation and lack efficient control mechanisms for power folding seats, leading to potential errors and incomplete folding due to lack of error detection and adaptive control modes.
Innovation Solution
A seat control system with a control unit and sensor assembly that detects error conditions, switching from dual seat mode to single seat mode to prioritize the completion of one seating module's movement over the other, ensuring reliable folding by overriding the second module's operation until the first is fully adjusted.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If dual seat mode is used to adjust both seating modules simultaneously, then operation efficiency is improved, but reliability deteriorates due to error conditions affecting both seats
Solution Approach 1:
The system dynamically switches between dual seat mode and single seat mode based on detected error conditions. The control unit monitors sensor inputs and automatically transitions from simultaneous adjustment of both seats to sequential adjustment, adapting the operation mode to maintain reliability while preserving efficiency when conditions permit
Solution Approach 2:
The control unit changes the operational parameters of the seating system by modifying the adjustment sequence. When an error condition is detected in one seating module, the system changes from adjusting both modules in parallel to adjusting only the unaffected module, thereby preventing error propagation while maintaining overall system productivity
2Reliability
If error detection and mode switching is implemented, then reliability is improved, but device complexity increases
Solution Approach 1:
The control unit implements a feedback mechanism by continuously monitoring sensor inputs from both seating modules during adjustment. When an error condition is detected, the system uses this feedback to automatically switch from dual seat mode to single seat mode, ensuring reliable operation without requiring complex manual intervention or additional hardware beyond the sensor-control unit integration

AI summary
A system and method for controlling movement of a seat in a vehicle includes first and second seating modules movable between an upright position and a folded position in response to actuation to at least one activation element. A control unit operably connected to the first and second seating modules is configured to receive input from the at least one activation element and generates a control signal to control movement of the first and second seating modules. The control unit deactivates movement of the second seating module until movement of the first seating module when the sensor assembly detects the error condition by the sensor assembly during adjustment of the seating modules.
