Abstract
A ventilation system includes a seat bottom blower unit configured to selectively draw an airflow into a seat bottom of the vehicle seat, a seat back blower unit configured to selectively draw an airflow into a seat back of the vehicle seat, and a controller in signal communication with the seat bottom blower unit and the seat back blower unit, the controller configured to generate a common pulse width modulation (PWM) duty cycle signal. The seat bottom blower unit is configured to operate at a first predetermined blower speed based on the common duty cycle signal, and the seat back blower unit is configured to operate at a second different predetermined speed based on the common duty cycle signal. The seat bottom blower unit and the seat back blower units are configured to simultaneously operate at different speeds based on the common duty cycle signal.
