Abstract

Perkembangan teknologi saat ini semakin pesat terutama dalam bidang otomotif. Mobil Plug-In Hybrid Electric Vehicle (PHEV) ITS dibawah naungan Pusat Unggulan Iptek bidang Sistem & Kontrol Otomotif (PUI-SKO) ITS dan Science Techno Park (STP) ITS merupakan salah satu inovasi dalam bidang otomotif ditengah krisis bahan bakar fosil yang setiap tahun terus berkurang tanpa dapat diperbaharui. Pemilihan Electric Power Steering (EPS) pada sistem kemudi salah satunya untuk mengantisipasi kekurangan pada sistem Hydraulic Power Steering (HPS) karena dinilai kurang efisien energi dan tidak ramah lingkungan. Penelitian ini menggunakan modul kolom kemudi dari mobil Toyota Agya sebagai model yang memiliki sensor torsi dan motor DC dengan memodifikasi sistem kontrol agar sesuai dengan karakteristik mobil PHEV ITS. Komponen sistem kontrol elektrik EPS terdiri dari mikrokontroller ESP32, rangkaian penurun tegangan, sensor torsi kemudi, sensor arus dan driver motor DC. Metodologi penelitian diawali dengan studi literatur mengenai perkembangan penelitian sistem kontrol EPS, observasi lapangan mengenai parameter mobil PHEV ITS, perancangan sistem kendali EPS, proses pembuatan kontroller, perakitan EPS pada platform pengujian PHEV ITS, serta pengujian sistem kontrol yang diawali dengan pengujian sensor arus, sensor torsi kemudi, torsi bantuan, dan input kecepatan kendaraan. Hasil dari pengolahan kontrol ini adalah respon sistem EPS mampu memberikan torsi bantuan yang proporsional dengan torsi input roda kemudi. Pengujian EPS dilakukan dengan memberikan torsi kemudi (Nm), memberikan variasi kecepatan (0km/jam-70km/jam) serta diberikan beban rack 10kg, diperoleh torsi bantuan semakin menurun dengan bertambahnya kecepatan kendaraan. Demikian pula arus motor DC juga menurun seiring dengan penambahan kecepatan kendaraan. Hal ini menunjukkan kerja EPS efektif dan memiliki performa yang baik serta memenuhi standar keselamatan kendaraan.

The development of technology is currently increasingly rapid, especially in the automotive field. ITS Plug-In Hybrid Electric Vehicle (PHEV) car under the auspices of the Centre for Excellence in Automotive Systems & Controls (PUI-SKO) ITS and Science Techno Park (STP) ITS is one of the innovations in the automotive field amid the fossil fuel crisis which continues to decrease every year without being renewed. The selection of Electric Power Steering (EPS) in the steering system is one of them to anticipate the shortcomings of the Hydraulic Power Steering (HPS) system because it is considered less energy efficient and not environmentally friendly. This research uses a steering column module from a Toyota Agya car as a model that has a torque sensor and DC motor by modifying the control system to match the characteristics of the ITS PHEV car. The EPS electrical control system components consist of an ESP32 microcontroller, voltage reducing circuit, steering torque sensor, current sensor and DC motor driver. The research methodology begins with a literature study on the development of EPS control system research, field observations of ITS PHEV car parameters, EPS control system design, controller manufacturing process, EPS assembly on the ITS PHEV test platform, and control system testing which begins with testing the current sensor, steering torque sensor, assist torque, and vehicle speed input. The result of this control processing is that the EPS system response is able to provide assistance torque proportional to the steering wheel input torque. EPS testing is done by providing steering torque (Nm), providing speed variations (0km/h-70km/h) and given a 10kg rack load, the assist torque is obtained decreasing with increasing vehicle speed. Similarly, the DC motor current also decreases with increasing vehicle speed. This shows that the EPS works effectively and has good performance and meets vehicle safety standards.
