Abstract

Mechanisms are provided for controlling air quality within an interior of a vehicle. Air quality data is received from a vehicle mounted sensor of the vehicle, and at least one of a sensor of another vehicle, an external environment sensor, or a remotely located information source system. A first air quality measure is determined for an external environment exterior to the vehicle and a second air quality measure of an internal environment of the vehicle is determined based on the air quality data. At least one control signal to send to a climate control system of the vehicle is determined based on the determined first air quality measure and determined second air quality measure. Air quality within the internal environment of the vehicle is controlled by sending the at least one control signal to the climate control system.
