VEHICLE HVAC NOISE CONTROL SYSTEM

摘要

A vehicle HVAC noise control system includes a controller. An air handler provides airflow to a passenger compartment. An inputting device sets a target temperature for the passenger compartment. A temperature sensor measures a current temperature within the passenger compartment. A sensor detects an ambient condition outside of the passenger compartment. A blower motor moves the air flowing through the air handler into the passenger compartment at an adjustable operating airflow rate. The controller is connected to the air handler, the inputting device, the temperature sensor, the exterior sensor, and the blower motor. The controller determines and implements adjustments to the operating airflow rate in order to reduce airflow noise level based on at least the ambient condition, a comparison between the target temperature and the current temperature within the passenger compartment and a noise level of the airflow in the passenger compartment.

1. A vehicle HVAC noise control system comprising:
an air handler providing airflow to a passenger compartment, the air handler including a heating source and a cooling source; an inputting device that sets a target temperature for the passenger compartment; a temperature sensor that measures a current temperature within the passenger compartment; at least one exterior sensor that detects an ambient condition outside of the passenger compartment; a blower motor operably connected to the air handler moving the air flowing through the air handler into the passenger compartment at an adjustable operating airflow rate; and a controller operatively connected to the air handler, the inputting device, the temperature sensor, the at least one exterior sensor, and the blower motor, the controller determining and implementing adjustments to the operating airflow rate in order to reduce airflow based on at least the ambient condition detected outside of the passenger compartment, a comparison between the target temperature and the current temperature within the passenger compartment and a noise level of the airflow in the passenger compartment.
