PROTOTYPE PENGATURAN KECEPATAN DAN KENDALI JARAK OTOMATIS PADA MOBIL LISTRIK TERHADAP BAHAYA KECELAKAAN MENGGUNAKAN METODE FUZZY LOGIC CONTROLLER (FLC)

Abstract

An electric car is a car that will move with a DC electric motor and utilize electrical energy. However, braking electric cars can only be done manually with the driver's estimate only. Therefore, to prevent accidents, an automatic speed control and distance control system is needed. This study aims to control the speed and braking of electric cars if there are objects in front of the electric car using the Fuzzy Logic Controller (FLC) method and make control of the distance of the car with objects on the left, right and rear. The research method used is controlling DC motors using FLC with input of motor speed and car distance to objects. Then difuzzification is carried out to determine the output action of the motor in the form of slowing down or stopping. The test was carried out by placing the object in front of the electric car with a very close distance (10 cm) to very far (400 cm). The results of prototype testing if without load, that is, the car will stop if the distance to the object < 50 cm with an average delay of 2.9 seconds. Meanwhile, if you use a load on the test starting from 100 cm, the car will stop on average at a distance of 70 cm because the motor torque is not strong. If the test starts at 200 cm, most cars crash because there is a delay in sensor readings.
