Abstract
A ventilation system for purging air contained with a vehicle interior is disclosed. The ventilation system includes a blower, a first vent, a second vent, at least one interior temperature sensor, at least one external temperature sensor, a motion sensor for windy days and dusty areas, a humidity sensor, a sunload sensor and a control module. The blower is a conventional vehicle air conditioning blower and is located within the vehicle interior for creating a pressure differential between the interior and exterior of the vehicle. The first vent expels air from the vehicle interior and the second vent draws external air into the vehicle interior. The at least one interior sensor is located within the vehicle interior for determining an interior condition of the vehicle. The at least one external sensor determines an external condition of environment external to the vehicle interior. Finally, the control module is in communication with the blower, first and second vents, interior and exterior sensors for monitoring the internal and exterior sensors and comparing the sensor outputs to predefined thresholds for actuating the blower, first and second vents to exhaust the air contained …
