Abstract

A front and rear integrated vehicle HVAC system includes a front HVAC part with a front blower and a front exhaust outlet, and a rear HVAC part with a rear blower and a rear exhaust outlet. The system includes a controller that determines a minimum voltage to be supplied to the rear blower to prevent reverse airflow from the rear outlet and / or rear blower air inlet. Then, the voltage supplied to the rear blower is set to the larger of the minimum rear blower voltage and the current rear blower voltage. The reverse airflow is the airflow located in the front HVAC section, generated by the front blower and intended for the front exhaust outlet, that penetrates into the rear HVAC section and exits the rear exhaust outlet and / or rear blower air inlet.

Description

technical field [0001] The present disclosure relates to a method and apparatus for controlling a vehicle HVAC system, and more particularly to a method for controlling a front-to-rear integrated vehicle HVAC system to prevent reverse air flow output from undesired exhaust outlets and / or blower inlets and device. Background technique [0002] To improve vehicle heating operations, heating, ventilation and air conditioning (HVAC) systems with individual climate control zone functions have been developed and implemented. The passenger compartment can generally be conceptually divided into a front area and a rear area, and further divided into a driver's side area and a passenger's side area. As used herein, the front area corresponds to the area where the driver and front passenger seats are located, while the rear area corresponds to the area of ​​the cabin where the rear seats are located. Depending on the independent climate control function, it is possible to provide cus...
