Vehicle windows control proportional to the speed, using raspberry and on board diagnostics port

The present work proposes a project to control the opening and closing of a vehicle's power Windows, using a Raspberry board with a graphical LCD touchscreen interface. The system, besides a manual mode to open and close the windows, incorporates a basic algorithm to read the vehicle's speed thru OBDII protocol (On Board Diagnostics). With the automatic mode engaged, if the vehicle's speed increases, the system opens a little the window, and in a similar way if the vehicle slows down the windows gets lower. For testing it was developed an OBD arduino emulator.
