Adaptive Vehicle Seat Control for Automatic Driving Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle seat control systems fail to secure a driver's field of vision during automatic driving modes, as they do not adapt the seat configuration to changes in driving modes, potentially hindering safety.
Innovation Solution
A vehicle seat control system with a first and second backrest portion, a folding adjustment unit, and a seat surface adjustment unit, controlled by a unit that detects angles and adjusts the seat configuration to maintain a reference height and restrict rotation angles to ensure the driver's field of vision is secured during automatic driving.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the seat is adjusted to a reclining state during automatic driving, then the driver's comfort is improved, but the driver's field of vision deteriorates
Solution Approach 1:
The patent applies dynamics by making the seat configuration adaptive to different driving modes. The control unit dynamically adjusts the seat parameters (backrest angles, seat surface height) based on whether the vehicle is in manual or automatic driving mode, transitioning from a fixed configuration to a dynamically adaptable one that maintains both comfort and safety
Solution Approach 2:
The patent changes physical parameters of the seat (folding angles of backrest portions, height of seat surface) based on driving mode. Specifically, it controls the folding adjustment unit to maintain the second angle within a predetermined range and adjusts the seat surface height to ensure the reference position height meets visibility requirements, thereby resolving the contradiction between comfort and field of vision
2Ease of operation
If the second angle of the second backrest portion is increased for relaxation, then the driver's comfort is improved, but the height of the reference position decreases, affecting visibility
Solution Approach 1:
The system dynamically controls the second angle of the second backrest portion based on driving mode. During automatic driving, the control unit maintains the second angle within a predetermined range that balances relaxation with visibility requirements, rather than allowing maximum reclination
Solution Approach 2:
The patent directly controls the folding adjustment unit to maintain the second angle within a predetermined range during automatic driving, and simultaneously adjusts the seat surface height parameter to compensate for any height reduction, ensuring the reference position height maintains adequate visibility
3Object-affected harmful factors
If the seat surface height is increased to maintain visibility, then the driver's field of vision is improved, but the driver's leg position may be affected
Solution Approach 1:
The system dynamically adjusts the seat surface height based on driving mode and current seat configuration. During automatic driving, it increases the seat surface height to maintain visibility while coordinating with backrest angle adjustments to minimize impact on leg position
Solution Approach 2:
The patent combines the control of multiple seat parameters (second angle of second backrest portion, seat surface height) into a coordinated adjustment system. The control unit simultaneously manages both parameters to achieve visibility improvement while minimizing disruption to the driver's leg position and overall seating comfort

AI summary
A vehicle seat control system (1) includes a first backrest portion (302) rotatably connected to a seating portion (301) by a first connection unit (308), a second backrest portion (302) rotatably connected to the first backrest portion by a second connection unit (309), a folding adjustment unit (304) that adjusts an angle of the second connection unit, a seat surface adjustment unit (304) that adjusts a height of the seating portion, a first angle detection unit (308a) that detects a first angle that is formed between the first backrest portion and a floor surface, a second angle detection unit (309a) that detects a second angle that is formed between the second backrest portion and the first backrest portion, and a control unit (160) that controls the folding adjustment unit on the basis of the first angle at the time of automatic driving of the vehicle to adjust the second angle, and controls the seat surface adjustment unit to maintain a height of a reference position in the second backrest portion to be equal to or greater than a reference height in a case that the height of the reference position in the second backrest portion is smaller than the reference height.
