Claims

[Scope of utility model registration request]

A vehicle interior comprising a sensor that detects air pollution inside the vehicle, a detection circuit that detects the output of this sensor, and a circuit that generates a control signal to operate the power windows when the detection circuit detects air pollution set in the vehicle interior. The ventilation system includes a circuit that detects a traveling speed inside a vehicle, and the control signal generation circuit changes the amount of window opening that is opened when air pollution set by the detection circuit is detected, in accordance with the detected vehicle speed. An in-vehicle ventilation system characterized in that the amount of ventilation when air pollution is detected is kept constant regardless of vehicle speed.
