DRIVER_DISTRACTION_WARNING_ENABLED
What it is
Enable or disable driver distraction warnings.
Set true to enable driver distraction warnings and false to disable driver distraction warnings.
When driver distraction warnings are enabled, the driver distraction monitoring system inside the vehicle should warn the driver when it detects the driver is distracted.
In general, DRIVER_DISTRACTION_WARNING_ENABLED should always return true or false. If the feature is not available due to some temporary state, that information must be conveyed through the ErrorState values in the DRIVER_DISTRACTION_WARNING property.
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 0x1120101f apart:
| Field | Mask | Value | Means |
|---|---|---|---|
| Group | 0xf0000000 | 0x10000000 | SYSTEM |
| Area | 0x0f000000 | 0x01000000 | GLOBAL |
| Type | 0x00ff0000 | 0x00200000 | BOOLEAN |
| Ordinal | 0x0000ffff | 0x0000101f | 0x101f |
Reading it from an app
CarPropertyManager mgr = (CarPropertyManager)
car.getCarManager(Car.PROPERTY_SERVICE);
boolean value =
mgr.getBooleanProperty(VehiclePropertyIds.DRIVER_DISTRACTION_WARNING_ENABLED, 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.
