HVAC_STEERING_WHEEL_HEAT
What it is
Steering Wheel Heating/Cooling
Sets the amount of heating/cooling for the steering wheel.
The maxInt32Value and minInt32Value in VehicleAreaConfig must be defined. All integers between minInt32Value and maxInt32Value must be supported.
The maxInt32Value indicates the maximum steering wheel heating setting. The minInt32Value should be 0, unless the vehicle supports steering wheel cooling as well. In such a case, the minInt32Value indicates the maximum steering wheel cooling setting.
This property is not in any particular unit but in a specified range of heating 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 0x1140050d apart:
| Field | Mask | Value | Means |
|---|---|---|---|
| Group | 0xf0000000 | 0x10000000 | SYSTEM |
| Area | 0x0f000000 | 0x01000000 | GLOBAL |
| Type | 0x00ff0000 | 0x00400000 | INT32 |
| Ordinal | 0x0000ffff | 0x0000050d | 0x50d |
Reading it from an app
CarPropertyManager mgr = (CarPropertyManager)
car.getCarManager(Car.PROPERTY_SERVICE);
int value =
mgr.getIntProperty(VehiclePropertyIds.HVAC_STEERING_WHEEL_HEAT, 0);This property can be read and written, though an OEM may implement it as read-only. It fires a callback whenever the value changes.
