SEAT_BACKREST_ANGLE_2_POS
What it is
Seat backrest angle 2 position
Backrest angle 2 is the next actuator up from the bottom of the seat.
The maxInt32Value and minInt32Value in VehicleAreaConfig must be defined. All integers between minInt32Value and maxInt32Value must be supported.
The minInt32Value indicates the seat backrest's full recline position w.r.t the next actuator in the backrest from the one at the bottom of the seat (see SEAT_BACKREST_ANGLE_1_POS for additional details). The maxInt32Value indicates the seat backrest's most upright/forward position w.r.t the next actuator in the backrest from the one at the bottom of the seat(see SEAT_BACKREST_ANGLE_1_POS for additional details).
Values in between minInt32Value and maxInt32Value indicate a transition state between the full recline and upright/forward positions.
This property is not in any particular unit but in a specified range of relative positions.
This property is defined as VehiclePropertyAccess.READ_WRITE, but OEMs have the option to implement it as VehiclePropertyAccess.READ only.
How the ID is built
A property ID is a 32-bit value packing four fields. Reading 0x15400b89 apart:
| Field | Mask | Value | Means |
|---|---|---|---|
| Group | 0xf0000000 | 0x10000000 | SYSTEM |
| Area | 0x0f000000 | 0x05000000 | SEAT |
| Type | 0x00ff0000 | 0x00400000 | INT32 |
| Ordinal | 0x0000ffff | 0x00000b89 | 0xb89 |
Reading it from an app
CarPropertyManager mgr = (CarPropertyManager)
car.getCarManager(Car.PROPERTY_SERVICE);
int value =
mgr.getIntProperty(VehiclePropertyIds.SEAT_BACKREST_ANGLE_2_POS, areaId);This property can be read and written, though an OEM may implement it as read-only. It fires a callback whenever the value changes.
