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




Information Types

Aligning on information types is critical

Seats

Seat identity for 3 rows with 3 seats  per row, front to back

  • row1_left

looking towards the front of vehicle from within the vehicle




General: Seating accounts for over 1/5th of VSS.yaml.  This is due to the many facets of seating and the number of instances.


Seat Configuration:

  • Vehicle.Cabin.SeatRowCount - number of rows - defaults to 2
  • Vehicle.Cabin.SeatPosCount - array of number of seats per row - defaults to 2,3 which is 2 in row 1 and 3 in row 2

Note:

  • Even though the default says only 2 seats in row 1, generated (yaml) it has Driver, Middle and Passenger

Related:

  • Vehicle.VehicleIdentification.VehicleSeatingCapacity - provides seating capacity vehicle
  • Vehicle.Cabin.DriverPosition - driver left, middle or right


Align with VSS.

Vehicle.Cabin.Seat is the complete seat definition.  Vehicle.Cabin.Seat.Row1.DriverSide would be an instance.

  • 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.
  • Vehicle.Cabin.Seat.Row1.DriverSide.Tilt - degrees -  In VSS it is assumed that tilting a seat affects both seating (seat bottom) and backrest, i.e. the angle between seating and backrest will not be affected when changing Tilt.

Did we somehow lose this?

  • 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.
  • 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.




Cushion Extension

Thigh Extension?

This is not a component.  Its a capability or a directiion?

Headrest






  • Vehicle.Cabin.Seat.Row1.DriverSide.Headrest - Headrest settings
  • Vehicle.Cabin.Seat.Row1.DriverSide.Headrest.Angle - degrees - Headrest angle, relative to backrest, 0 degrees if parallel to backrest, Positive degrees = tilted forward.
  • 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.
