INDOOR OXYGEN CONCENTRATION CONTROL SYSTEM FOR A VEHICLE, CAPABLE OF DETECTING AND CONTROLLING THE OXYGEN CONTENT OF AN INTERIOR SPACE

摘要

PURPOSE: An indoor oxygen concentration control system for a vehicle is provided to make agreeable environment by maintaining the oxygen content of a vehicle interior over standard value.;CONSTITUTION: An indoor oxygen concentration control system for a vehicle comprises an oxygen sensor(10), an internal air/external air converting driver(30), a control unit(20), an external air sensor, and an automatic temperature controller. The oxygen sensor senses the oxygen content of the internal air in the motion of the vehicle. The internal air/external air converting driver draws in the external air or circulates the internal air. The control unit draws in the external air by controlling the internal air/external air converting driver. The external air sensor senses the toxic gas concentration of the external air. The automatic temperature controller receives control signals from the control unit and controls the internal air/external air converting driver.;COPYRIGHT KIPO 2010
