AUTOPILOT SYSTEM IN MODERN VEHICLES 1 Introduction An autopilot is a system used to control the path of an aircraft, marine craft or spacecraft without requiring constant manual control by a human operator. Autopilots do not replace human operators. Instead, the autopilot assists the operator's control of the vehicle, allowing the operator to focus on broader aspects of operations (for example, monitoring the trajectory, weather and on-board systems). Autopilot enables your car to steer, accelerate and brake automatically within its lane. Current Autopilot features require active driver supervision and do not make the vehicle autonomous. Such system is developed to reduce the work load of human pilots in order to lessen their fatigue and reduce operation errors during long flights. 2 History of Autopilot system In the past, pilots were required to give their undivided attention for the whole duration of the flight in order to fly safely. As technology improves and the aviation world transitions into the modern world, autopilot was introduced to aid pilots during long journeys. To get relief from his problem, Automation of Planes Began 9 Years After the Wright Bros Took Flight—But It Still Leads to Baffling Disasters. Autopilot has existed since 1912. But some experts worry that too much plane automation introduces danger. Autopilot has existed since 1912. After that Bill Lear developed his F-5 automatic pilot and automatic approach control system, and was awarded the Collier Trophy in 1949. 3 The features of modern auto pilot system Automatic pilots consist of four major elements: (1) a source of steering commands (such as a computerized guidance program or a radio receiver), (2) motion and position sensors (such as gyroscopes, accelerometers, altimeters, and airspeed indicators), (3) a computer to compare the parameters specified in the guidance ... 4 The 3 levels of autopilots Single-axis autopilots controls the aircraft in roll axis only with the help of ailerons aka “wing levelers”. Two-axis autopilots can control an aircraft in pitch axis as well as roll axis with the help of ailerons & elevators. The three-axis autopilot systems are capable of controlling an aircraft in all the 3 axes- roll, pitch & yaw with the help of all three – ailerons, elevators & rudder. 5 6 7 8 9
