GPS-Aided Auto Navigation System for Autonomous Vehicles

Autonomous Vehicles (AV) are the future of the smart digital world. Auto Navigation is the heart of AVs. However, researchers have been working on precise auto navigation control of AVs for many years. Hence, In this paper, a GPS-aided auto navigation system is proposed with position control and heading control of AV. Further, to test the proposed algorithm an AV is designed and developed with low-cost sensors and actuators. The real-time testing of the proposed adaptive control auto navigation mechanism has been performed with three test cases such as straight line, L-shaped and Semi-circular. The results shown in this paper are the deviation between the travelled path and the defined path of the vehicle in different trajectories by assuming no obstacles in the path. The deviation of the path travelled by AV with respect to the defined path using the proposed algorithm is less than 0.5m. Finally, the telemetry of AV has been monitored by the developed Graphical User Interface (GUI). This work is very useful in auto navigation of vehicles where humans can not be sustained.
