Vehicle Seat Walk-In Control for Slide and Recline Coordination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing seat control systems struggle to provide a convenient user experience for getting on and off a vehicle seat due to limited control mechanisms, leading to gaps between slide location and reclining angle adjustments.
Innovation Solution
A seat control apparatus with a first driving part for slide location control and a second driving part for reclining angle control, along with a fixing part and a controller, adaptsively changes the seat's operation mode based on user inputs, using sensors to identify previous modes and adjust accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixing part is used to control slide location, then the seat can be fixed to a specific position, but the driving part cannot be adapted when the operation mode changes
Solution Approach 1:
The fixing part is designed to dynamically change its state between locked and unlocked positions based on the operation mode. When the seat is in walk-in mode, the fixing part unlocks to allow slide location adjustment; when in normal mode, it locks to maintain position stability. This dynamic adaptation resolves the contradiction between reliability and adaptability.
2Reliability
If the slide location is controlled by a fixing part, then the seat can maintain a fixed position, but the control system cannot identify previous operation modes accurately
Solution Approach 1:
The control system incorporates feedback mechanisms including sensors that detect the fixing part's locked/unlocked state and the seat's current position. This feedback loop allows the controller to accurately identify the previous operation mode and make appropriate adjustments, preventing information loss about the seat's operational state.
3Device complexity
If the same driving part is used for both walk-in and un-walk-in modes, then the device structure is simplified, but gaps are generated between slide location and reclining angle
Solution Approach 1:
The system dynamically adjusts the reclining angle based on the operation mode. In walk-in mode, the reclining angle is adjusted to a larger value to facilitate easier entry; in un-walk-in mode, it returns to a smaller value. This dynamic adjustment, coordinated with slide location control, eliminates gaps between the two parameters while maintaining a relatively simple driving part structure.

AI summary
A seat control apparatus includes a first driving part, a second driving part and a controller. The apparatus is configured to receive a user input on a walk-in mode through an input part, and based on the received user input, the apparatus controls a slide location of a seat to a walk-in location area corresponding to the walk-in mode by using the first driving part, and controls a reclining angle of the seat to a walk-in angle area corresponding to the walk-in mode by using the second driving part. In particular, when the user input is received again through the input part, the apparatus restores the reclining angle of the seat from the walk-in angle area to an un-walk-in angle area by using the second driving part.
