Automatic Car Parking System Essay
Abstract—This Paper proposes the development of an Automatic Car Parking System imparting performance. This proposed framework uses sensors, electric power steering, path planning, path tracking and pure pursuit algorithm. The verification of the vehicle was demonstrated using the electric power steering for tracking the path. An ultrasonic sensor is used to determine the availability of the parking space. Drivers can uses user interactive interface to check if the parking space is big enough. Steering movements takes place based on the pure pursuit algorithm and inertial navigation methods. Appraisal and simulation results show good behavior. The parking required is 1.5 longer than the length …show more content…

III. AUTOMATIC CAR PARKING SYSTEM
This has been implemented on microcontroller. This core task is divided into two procedures. The first duty is to press the push-parking button on the touch panel, which is already in built in the steering wheel. Now, the microcontroller will calculate the distance travelled by the vehicle from WPT and converts the distance. The work of the driver is to choose the available parking space.

Look ahead distance has less oscillation and converges easily. Moreover, there is a decrease in the deviation with the shorter look ahead distance. In this experiment the look ahead distance is 200.Equation (5) and (6) may sound simple at first but it is trivial to produce the correct distance travelled than our expectations. The original wheel diameter may differ from the nominal wheel diameter. Though, RTK- GPS provides accurate position, it is very expensive in real world applications . The inner surface and outer surface of the wheel travel ate different distances.A feed-forward controller can be used in designing the tracking algorithms. A controller can be used to control the steering
