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 Type	Definition	Illustration #	BMW	Ford	GM	Volvo Cars	VSS Mapping	Android
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

Moveable (Electrically Driven) Seating Component	Complete seat	All	Added				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.	SEAT_FORE_AFT SEAT_HEIGHT
	Lumbar	5					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.	SEAT_LUMBAR_FORE_AFT SEAT_LUMBAR_SIDE_SUPPORT SEAT_LUMBAR_VERTICAL
	Cushion Side Bolstewr	Need number	Pictures would be good focus must be on Mechatronic components	Right and Left Back (upper) bolsters		Infalation level 0-100%
	Backrest Side Bolster	8		Right and Left Cushion (lower) bolsters		Inflation level 0-100%	Vehicle.Cabin.Seat.Row1.DriverSide.Backrest.SideBolster - Backrest side bolster (lumbar side support) settings. Vehicle.Cabin.Seat.Row1.DriverSide.Backrest.SideBolster.Support percent - Side bolster support. 0 = Minimum support (widest side bolster setting). 100 = Maximum support.
	Upper Shoulder (fwd/backward)	9
	Backrest (was Cushion Front)	10		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	Blue thing		Thigh Extension? see video		Either works
	Fold Seat					Row 3, Row 2, and possibly row 1 passenger seat
	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.

General questions regarding API invocation:

Can we use "actuate with commands, report with signals" as a general strategy?
Do we use transaction IDs to tie commands to output signals/results?
