Seats Seat identity for 3 rows with 3 seats per row, front to back | |
| 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.
|
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 - umbar support (in/out position). 0 = Innermost position. 100 = Outermost position.

|
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.

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.
