Abstract
A method of operating a vehicle climate system includes, by a controller, responsive to a same blower motor request, operating a blower motor at a first speed responsive to a heater core isolation valve (HCIV) directing coolant used to heat a cabin to an engine. The method further includes, by the controller, responsive to the same blower motor request, operating the blower motor at a second speed less than the first speed responsive to the HCIV directing the coolant to an electric heater and not to the engine.
Claims20
A method of operating a vehicle climate system, comprising:
- by a controller, responsive to a same blower motor request,
- operating a blower motor at a first speed responsive to a heater core isolation valve (HCIV) directing coolant used to heat a cabin to an engine;
- and
- operating the blower motor at a second speed less than the first speed responsive to the HCIV directing the coolant to an electric heater and not to the engine.
A method of operating a vehicle climate system, comprising:
- by a controller, responsive to a same blower motor request,
- operating a blower motor at a first voltage when an engine coolant temperature (ECT) is higher than a heater core temperature (HCT);
- and
- operating the blower motor at a second voltage lower than the first voltage when the ECT is lower than the HCT.
A method of operating a vehicle climate system, comprising:
- by a controller, responsive to a same blower motor setting and ambient temperature being less than a predefined threshold,
- reducing a same maximum blower motor speed and modifying a user-interface to indicate a decreased maximum blower motor speed responsive to a heater core isolation valve (HCIV) configuration change from a first configuration to a second configuration;
- and
- maintaining the same blower motor speed and modifying the user-interface to indicate increased maximum blower motor speed responsive to a HCIV configuration change from the second configuration to the first configuration.
