Vehicle Seat Path Control Around Nearby Occupants
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle seat control systems do not effectively prevent interference between moving seats and occupants in other seats, leading to potential collisions and discomfort.
Innovation Solution
A vehicle seat control device that acquires seat arrangement information, identifies movement paths, detects occupants, and adjusts movement speed or distance to avoid interference, including the option to cancel movement or issue warnings to prevent collisions.

Engineering Contradiction Analysis
1Productivity
If the moving seat moves along the identified movement path from the first seat arrangement to the second seat arrangement, then the seat repositioning function is achieved, but interference with occupants in other seats may occur
Solution Approach 1:
The system performs preliminary detection of occupants in other seats before the moving seat begins its movement. The occupant detection section identifies occupants in advance, and based on this information, the control section determines the appropriate movement strategy (reducing speed, shortening distance, or canceling movement) before the actual movement occurs, thereby preventing interference proactively
Solution Approach 2:
The movement parameters of the seat are made dynamic and adjustable based on real-time conditions. The control section can reduce movement speed, shorten movement distance, or cancel movement entirely depending on the detected occupant positions. This dynamic adjustment allows the system to optimize between repositioning efficiency and occupant safety rather than following a fixed movement protocol
2Object-affected harmful factors
If the movement speed of the moving seat is reduced to suppress interference, then occupant safety is improved, but the time required for seat repositioning increases
Solution Approach 1:
The system applies partial action by selectively reducing movement speed only in the specific zones where occupants are detected, rather than reducing speed uniformly throughout the entire movement path. The control section determines the degree of speed reduction based on the proximity and position of detected occupants, applying minimal necessary adjustments to maintain efficiency while ensuring safety
3Object-affected harmful factors
If the movement distance of the moving seat is shortened to avoid interference, then collision prevention is improved, but the seat cannot reach the desired position
Solution Approach 1:
The system calculates the optimal movement distance in advance by considering the positions of detected occupants. Before executing movement, the control section determines the safe stopping position that maintains both collision prevention and position accuracy. This preliminary calculation ensures the seat moves as far as safely possible toward the target position without causing interference
Solution Approach 2:
The system uses feedback from the occupant detection section to continuously monitor and adjust the movement parameters. As the seat moves, the system receives real-time information about occupant positions and adjusts the movement distance accordingly, ensuring the seat reaches the maximum possible distance toward the target position while maintaining safety margins

AI summary
The processor is configured to acquire (S100) position information of a first seat arrangement representing current seat positions of plural seats that are configured to be capable of moving in a cabin interior, acquire (S 102) position information of a second seat arrangement representing post-movement seat positions of the plural seats, identify (S108, S114, S120) a movement path of a moving seat of the plural seats when moving from the acquired first seat arrangement to the acquired second seat arrangement, detect (S106, S112, S118) occupants sitting on the plural seats, and operate the moving seat so as to move the moving seat along the identified movement path. In a case in which an occupant sitting on another seat disposed peripherally to the movement path of the moving seat has been detected, the processor is configured to either control so as to execute any one action of the group consisting of reducing (S 124) a movement speed of the moving seat, canceling (S132) movement of the moving seat, and shortening (S126) a movement distance of the moving seat.
