A Self-Regulated Module for Vehicle Interior Ventilation System

Background/Objectives: The sunlight heats up closed area which is free of air and in close contact with sun much faster and significantly. This project is used to reduce the very high temperatures present inside the vehicles to feel very comfortable. Methods/Statistical Analysis: This paper proposes a CAN based module for self-regulated inside ventilation of vehicles to reduce the high temperatures presented inside the vehicles in summer. Two microcontrollers and a group of sensors which facilitate efficient, reliable, safe ventilation and sufficient data to ensure functional are used by this project. The communication using CAN bus is established between two ARM controllers. By changing the windows of the vehicle to open position, the ventilation process is performed. The position of the windows is controlled by the controller itself and without presence of driver using an algorithm that gives the details of sensors. Findings: The movements observed near the vehicle, precipitation and others have importance besides temperature for the ventilation. The results of the tests give usefulness and the modules utilization, the windows of the vehicle is closed when the temperature inside the vehicle achieves more than comfortable temperature and if any fire accidents, thefting of vehicle occurs then the location of the vehicle is sent to the user. Application/Improvements: The system provides comfortability to the users with a low cost. It saves the fuel by reducing the usage of AC. This system can be used in home and own vehicles, cabs, and transport business.
