HVAC_SEAT_TEMPERATURE
What it is
Seat heating/cooling
The maxInt32Value and minInt32Value in VehicleAreaConfig must be defined. All integers between minInt32Value and maxInt32Value must be supported.
The maxInt32Value indicates the maximum seat temperature heating setting. The minInt32Value must be 0, unless the vehicle supports seat cooling as well. In this case, minInt32Value indicates the maximum seat temperature cooling setting.
This property is not in any particular unit, but in a specified range of relative temperature settings.
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 0x1540050b apart:
| Field | Mask | Value | Means |
|---|---|---|---|
| Group | 0xf0000000 | 0x10000000 | SYSTEM |
| Area | 0x0f000000 | 0x05000000 | SEAT |
| Type | 0x00ff0000 | 0x00400000 | INT32 |
| Ordinal | 0x0000ffff | 0x0000050b | 0x50b |
Reading it from an app
CarPropertyManager mgr = (CarPropertyManager)
car.getCarManager(Car.PROPERTY_SERVICE);
int value =
mgr.getIntProperty(VehiclePropertyIds.HVAC_SEAT_TEMPERATURE, 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.
