An emulation of autonomous parallel parking system using fuzzy logic control

This paper represents an emulation of fuzzy logic control schemes in autonomous parallel parking system in a backward maneuver. There are four infrared sensors sending distance data to microcontroller for generating an obstacle-free parking path. Two of them mounted on the front and rare wheels on the parking side are used as the inputs to the fuzzy rules to calculate a proper steering angle while backing. The other two attached to the front and rear ends serve for avoiding collision with other cars along the parking space. At the end of parking process, the vehicle will be in line with other parked cars and position in the middle of the free space. A construction of fuzzy rules is designed based upon a wall following process. The effectiveness of the controller design is demonstrated in the experimental results.
