Notes from Kickoff

Below is the start of translating the uServices definitions of seating capabilities to a technology neutral tabular format as agreed in our kick-off meeting on October 18th.  Please take a look, iterate, comment and let me know if you have questions Paul Boyes 


Agreed by Group:

  • Start a position D in architecture - see architecture diagram below
  • Safety considerations to be noted but not exhaustively

  • top =5a
  • mid =5b
  • lower =5c





  • Vehicle.Cabin.Seat.Row1.DriverSide.Backrest.Lumbar - Adjustable lumbar support mechanisms in seats allow the user to change the seat back shape.
    • Vehicle.Cabin.Seat.Row1.DriverSide.Backrest.Lumbar.Height - mm - Height of lumbar support. Position is relative within available movable range of the lumbar support. 0 = Lowermost position supported.
    • Vehicle.Cabin.Seat.Row1.DriverSide.Backrest.Lumbar.Support - percent - lumbar support (in/out position). 0 = Innermost position. 100 = Outermost position.

same as cushion above or is this "Back"?

  • Vehicle.Cabin.Seat.Row1.DriverSide.Backrest - Describes signals related to the backrest of the seat.


Cushion Extension

Blue thing


Thigh Extension?

Either works


Headrest






  • Vehicle.Cabin.Seat.Row1.DriverSide.Headrest - Headrest settings
    • Vehicle.Cabin.Seat.Row1.DriverSide.Headrest.Height - mm Seat position on vehicle z-axis. Position is relative within available movable range of the seating. 0 = Lowermost position supported.


Airbag






  • Vehicle.Cabin.Seat.Row1.DriverSide.Airbag
    • Vehicle.Cabin.Seat.Row1.DriverSide.Airbag.IsDeployed - boolean - Airbag deployment status. True = Airbag deployed. False = Airbag not deployed.
  • Vehicle.Cabin.Seat.Row1.PassengerSide.Airbag


DirectionDirection of seat or component movement
  • Forward - toward the front of the vehicle

Needs Clarification.
Percent of total? clicks? x, y, z axis values?		foredepends on the component

AI:  align this definition .   Is Fold a direction?
  • Backward - toward the back of the vehicle

aftdepends on the component



  • Up - toward the roof of the vehicle


depends on the component

relates to height like:

  • Vehicle.Cabin.Seat.Row1.DriverSide.Backrest.Lumbar.Height


  • Down - toward the bottom of the vehicle


depends on the component



  • Inflate - fill with air

increasedepends on the component



  • Deflate - remove air

decreasedepends on the component



  • Tilt / Recline (angles)

anglesdepends on the component

Like:

  • Vehicle.Cabin.Seat.Row1.DriverSide.Backrest.Recline -

degrees - Seat z-axis depends on seat tilt. This means that movement of backrest due to seat tilting will not affect Backrest.Recline as long as the angle between Seating and Backrest are constant. Absolute recline relative to vehicle z-axis can be calculated as Tilt + Backrest.Recline.

  • Vehicle.Cabin.Seat.Row1.DriverSide.Headrest.Angle -

degrees - Headrest angle, relative to backrest, 0 degrees if parallel to backrest, Positive degrees = tilted forward.



  • Swivel







Position

position on horizontal plane (x-axis) or vertical plane (z-axis) of seat or component




needs clarification

Position vs Direction

Should height be separate from position?

Is y-axis ever needed?



  • Vehicle.Cabin.Seat.Row1.DriverSide.Position -

Seat position on vehicle x-axis. mm - Position is relative to the frontmost position supported by the seat. 0 = Frontmost position supported.

  • Vehicle.Cabin.Seat.Row1.DriverSide.Height -

mm - Seat position on vehicle z-axis. Position is relative within available movable range of the seating. 0 = Lowermost position supported.

Aligned? - ?


AI:  align what position means


Tilt Angle


tilt angle of seat or component (also known as recline)


duplicate to Tilt / Recline (angles)

duplicate to Tilt / Recline (angles) under "direction" above



  • Vehicle.Cabin.Seat.Row1.DriverSide.Backrest.Recline -

degrees - Seat z-axis depends on seat tilt. This means that movement of backrest due to seat tilting will not affect Backrest.Recline as long as the angle between Seating and Backrest are constant. Absolute recline relative to vehicle z-axis can be calculated as Tilt + Backrest.Recline.

  • Vehicle.Cabin.Seat.Row1.DriverSide.Headrest.Angle -

degrees - Headrest angle, relative to backrest, 0 degrees if parallel to backrest, Positive degrees = tilted forward.
