Vehicle HVAC noise control system
First Claim
1. A vehicle HVAC noise control system, comprising:
- an air handler connected to a passenger compartment within a vehicle;
a blower operably connected to the air handler to provide a plurality of airflow rates for air flowing into the passenger compartment;
an audio event device configured to electronically produce an audio event to the passenger compartment, where the audio event device consists of one or more of the following group of devices;
a mobile communication device, a navigation system and a window sensor; and
a controller operatively connected to the blower and the audio event device, the controller controlling operation of the blower initially at an operating airflow rate and in response to a signal from the audio event device indicating that the audio event device will subsequently produce the audio event the controller switches the blower to a noise reducing airflow rate, with the audio event occurring thereafter, where the signal consists of one or more of the following;
an indication of an incoming communication is being received by the mobile communication device;
an indication of that the navigation device is about to issue audible navigation instruction output;
an indication that the window sensor has detected that a window of the passenger compartment is being opened; and
an indication that an audio event device within the vehicle is about to produce an audio output that is intended to assist the vehicle operator or passenger.

Abstract
A vehicle HVAC noise control system includes an air handler, a blower motor, an audio event device and a controller. The air handler is connected to a passenger compartment. The blower motor is operably connected to the air handler to provide a plurality of airflow rates for air flowing into a passenger compartment. The audio event device produces an audio event to the passenger compartment. The controller is operatively connected to the blower motor and the audio event device. The controller controls operation of the blower motor initially at an operating airflow rate and subsequently switches to a noise reducing airflow rate in response to a signal from the audio event device indicating that the audio event device will subsequently produce the audio event.
