Abstract
A system and a method are provided for controlling a rotating type seat of a self-driving vehicle. In particular, seat position and bolster volume are adjusted based on a pressure rate in response to a vehicle turning when seat of the self-driving vehicle is rotationally adjusted in a desired direction. Accordingly, body displacement due to a centrifugal force and inertia is supported and a stable seating feeling is provided to the passenger.
Claims16
A system for controlling a rotating type seat of a self-driving vehicle, comprising:
- a driving information analyzing unit configured to obtain vehicle information and calculate a corrected lateral acceleration;
- a measuring unit configured to measure pressure exerted onto a seat back and a seat cushion using a sensor and configured to measure a seat rotation angle;
- a body pressure information analyzing unit configured to measure bolster body pressure occurrence rates of the seat back and the seat cushion based on pressure information from the measuring unit;
- a turning phase determining unit configured to determine a turning degree the vehicle using the seat rotation angle, the corrected lateral acceleration, and the bolster body pressure occurrence rate;
- and
- a seat controller configured to adjust an inclined angle of the seat cushion and bolster volume and angle of the seat back based on the turning degree.
A method for controlling a rotating type seat of a self-driving vehicle, comprising:
- calculating, by a controller, a corrected lateral acceleration;
- measuring, by the controller, pressure exerted onto a seat back and a seat cushion and measuring a seat rotation angle;
- calculating, by the controller, bolster body pressure occurrence rates of the seat back and the seat cushion based on pressure information;
- determining, by the controller, a turning degree of the vehicle using the seat rotation angle, the corrected lateral acceleration, and the bolster body pressure occurrence rate and determining a current degree of turning of the vehicle as Phase 0 (no turning), Phase 1 (proper turning), and Phase 2 (excessive turning) to provide it to a seat controller;
- and
- v) in the seat controller, adjusting an inclined angle of the seat cushion and bolster volume and angle of the seat back based on the turning degree.
