ClimateControl QML Type

Provides an interface to the climate control. More...

Import Statement: import QtInterfaceFramework.VehicleFunctions 1.0
Instantiates: QIfClimateControl




Detailed Description

The QIfClimateControl provides an interface to the climate control of the vehicle.

The climate control properties are divided into two categories: central or zoned. The central properties are exposed directly through the QIfClimateControl and the zoned properties are exposed through zone objects. The zones are retrieved using the zoneAt method.

The QIfClimateControl expects a single backend to be available. It is recommended to use it with discoveryMode set to AutoDiscovery.

Property Documentation

airConditioningEnabled : bool

Holds whether the air conditioning is enabled.

airflowDirections : QtIfVehicleFunctions::AirflowDirections

Holds the combination of flags indicating the areas where airflow is on.

Available values are:

WindshieldDirect airflow along the windshield.
DashboardDirect airflow through the dashboard.
FloorDirect airflow to the floor.

automaticClimateFanIntensityLevel : int

Holds the intensity level of the fan when the climateMode is set to AutoClimate.

climateMode : QtIfVehicleFunctions::ClimateMode

value holds the climate mode

Available values are:

ClimateOffThe climate system is turned off.
ClimateOnThe climate system is turned on.
AutoClimateThe climate system is in automatic mode and is adjusting some parts of the system automatically. E.g. lower the fan speed when the targetTemperature is reached.

configurationId : string

Holds the id to determine which configuration this feature belongs to.

Once the id has been set, it is possible to change certain values using the InterfaceFrameworkConfiguration API.

Note: Values set in the matching InterfaceFrameworkConfiguration can override the initial values set during the component creation.

See also InterfaceFrameworkConfiguration.

defrostEnabled : bool

Indicates whether the defrost mode is enabled. Usually that means that the fans are on the highest level to remove ice from the windshield.

discoveryMode : enumeration

Holds the mode that is used for the autoDiscovery

Available values are:

NoAutoDiscoveryNo auto discovery is done and the ServiceObject needs to be set manually.
AutoDiscoveryTries to find a production backend with a matching interface and falls back to a simulation backend if not found.
LoadOnlyProductionBackendsOnly tries to load a production backend with a matching interface.
LoadOnlySimulationBackendsOnly tries to load a simulation backend with a matching interface.

If necessary, auto discovery is started once the feature creation is completed.

Note: If you change this property after the feature is instantiated, make sure to call startAutoDiscovery() to search for a new service object.

[read-only] discoveryResult : enumeration

The result of the last autoDiscovery

Available values are:

NoResultIndicates that no auto discovery was started because the feature has already assigned a valid ServiceObject.
ErrorWhileLoadingAn error has happened while searching for a backend with a matching interface.
ProductionBackendLoadedA production backend was loaded, as a result of auto discovery.
SimulationBackendLoadedA simulation backend was loaded, as a result of auto discovery.

fanSpeedLevel : int

Holds the fan speed level

heaterEnabled : bool

Indicates whether the heater is enabled.

[read-only] isInitialized : bool

Indicates whether the feature has been initialized with all the values from the backend.

The property is true once the backend sends the QIfFeatureInterface::initializationDone signal to indicate that all values have now been initialized with values from the backend.

See also isValid and QIfFeatureInterface::initializationDone.

[read-only] isValid : bool

Indicates whether the feature is ready for use.

The property is true if the feature is ready to be used, otherwise false. Not being ready usually indicates that no suitable service object could be found, or that automatic discovery has not been triggered.

The backend still might not have sent all properties yet and is not fully initialized. Use isInitialized instead to know when the feature holds all correct values.

See also QIfServiceObject, discoveryMode, and isInitialized.

outsideTemperature : int

Holds the outside temperature of the zone expressed in centigrades

outsideTemperatureLabel : QString

The outside temperature expressed as a string, e.g. "mild"

preferredBackends : list<string>

Holds a list of wildcards to load the preferred backend during auto discovery.

The auto discovery mechanism will automatically search for backends which provide a matching interface for this feature implementation. See startAutoDiscovery() for more information.

In case multiple backends implement the same interface, the list of wildcards can be used to determine the correct one to load.

The wildcards are applied in order to the found backends. If the wildcard matches some backends those backends will be loaded, otherwise the next wildcard is used.

For example: Given an AbstractFeature with two backends, and, the property can be set to "*_mqtt*" to always select the backend when available.

recirculationEnabled : bool

Indicates whether the recirculation is currently running.

recirculationMode : QtIfVehicleFunctions::RecirculationMode

Holds the current recirculation mode

Available values are:

RecirculationOffThe recirculation is turned off.
RecirculationOnThe recirculation is turned on.
AutoRecirculationThe recirculation is turning off and on automatically depending on the air quality.

recirculationSensitivityLevel : int

Holds the sensitivity level of the recirculation system when the recirculationMode is set to AutoRecirculation.

seatCooler : int

Holds the seat cooler level

seatHeater : int

Holds the seat heater level

serviceObject : ServiceObject

Sets the service object for the feature.

As Features only expose the front API facing the developer, a service object implementing the actual function is required. This is usually retrieved through the auto discovery mechanism.

The setter for this property returns false if the QIfServiceObject is already set to this particular instance or the QIfServiceObject isn't accepted by the feature.

See also discoveryMode.

steeringWheelHeater : int

Holds the steering wheel heater level

targetTemperature : qreal

Holds the target temperature of the zone expressed in centigrades

zoneSynchronizationEnabled : bool

Indicates whether the zone synchronization is enabled.

Which zones and properties are synchronized is controlled by the backend implementing it.

Method Documentation

enumeration startAutoDiscovery()

Performs an automatic discovery attempt.

The feature tries to locate a single ServiceObject that implements the required interface.

If no ServiceObject is found, the feature remains invalid. If more than one ServiceObject is found, the first instance is used.

This function returns either the type of the backend that was loaded; or an error.

If the discoveryMode is set to QIfAbstractFeature::NoAutoDiscovery, this function does nothing and returns QIfAbstractFeature::NoResult.

Return values are:

NoResultIndicates that no auto discovery was started because the feature already has a valid ServiceObject assigned.
ErrorWhileLoadingIndicates an error has occurred while searching for a backend with a matching interface.
ProductionBackendLoadedA production backend was loaded, as a result of auto discovery.
SimulationBackendLoadedA simulation backend was loaded, as a result of auto discovery.
