Overtaking assistant system (OAS) with fuzzy logic method using camera sensor

Overtaking assistant system (OAS) is one of ADAS' subsystem that assists the driver on overtaking decision making. In this research, an OAS for overtaking one vehicle on one-way road and two-way road is realized using radio control (RC) car. Fuzzy logic is used as the overtaking decision making method with the distance of the overtaken and approaching RC car as the input, while the output is one of three movement decisions which is approaching the overtaken car, delaying overtaking, or overtaking. Overtaking will be performed on safe distance condition based on fuzzy logic rule. Overtaking delay will be performed if the distance is perceived as not safe enough. Pixy CMUcam5 is functioned as the distance sensor to convert other RC car's pixel width into the distance between the said RC car and this system. The test result shows that this system can overtake one RC car in front of it with high success rate on both one-way and two-way road.
