Automatic control is a principal concept of modern technology and plays a major role in robotics, aviation, defense industry and is an integral part of modern production and industrial processes. This concept has wide ranging applications in design of controlled machine tools, drones and light and heavy vehicles. The variables used in this paper for automatic control of the vehicle include distance from front vehicle, wheel position, steering wheel angle, and vehicle speed. The automatic control is carried out using fuzzy logic and GPS systems in four scenarios. In each scenario, simulation is performed on 10 films prepared for this purpose. The results point to success of implemented approach in speed control, overtaking process, and control of steering wheel angle with respect to car's movements.
