Abstract

A front and rear integrated vehicle HVAC system includes a front HVAC portion with a front blower and a front vent outlet, and a rear HVAC portion with a rear blower and a rear vent outlet. The system includes a controller that determines a minimum voltage to be supplied to the rear blower to prevent an inverse air flow from being expelled from the rear outlet and/or a rear blower air intake. A voltage supplied to the rear blower is then set as the greater of the minimum rear blower voltage and a current rear blower voltage. The inverse air flow is air flow in the front HVAC portion generated by the front blower and intended for the front vent outlet that seeps into the rear HVAC portion and is expelled from the rear vent outlet and/or the rear blower air intake.
