Abstract

Antilock Braking System (ABS) menjadi teknologi pengereman yang umum digunakan. ABS dirancang untuk mencegah roda kendaraan terkunci saat melakukan pengereman, karena roda terkunci dapat mengganggu keseimbangan dan stabilitas kendaraan, serta berpotensi menyebabkan kecelakaan. Kinerja ABS tidak hanya berfokus pada memperpendek jarak pengereman, tetapi juga pada menjaga keseimbangan dan stabilitas kendaraan.Tugas akhir ini akan dilakukan analisa sistem pengereman pada kendaraan Multipurpose Electric Vehicle ITS (MEvITS). Analysis diawali dengan menganalisa gaya-gaya selama pengereman pada kendaraan dalam bentuk free body diagram. selanjutnya, gaya-gaya yang sudah dianalisis akan disusun ke dalam bentuk model matematis. Kemudian, model matematis tersebut dibentuk ke dalam block diagram pada Simulink. Langkah berikutnya merupakan pelaksanaan simulasi pemodelan ABS dan LBS dengan dua variasi kecepatan. Simulasi pertama dilakukan untuk kecepatan 20 km/jam, dan 40 km/jam serta variasi kondisi jalan datar dan menurun. Hasil simulasi yang diperoleh berupa respons waktu pengereman, stopping distance, perlambatan, dan perilaku belok dari kendaraan. Dari analisa yang dilakukan, ditemukan bahwa sistem pengereman ABS memiliki stopping distance yang lebih pendek daripada sistem pengereman LBS pada berbagai kecepatan dan kondisi jalan. Selain itu, waktu pengereman yang diperlukan oleh ABS juga lebih singkat dibandingkan LBS pada variasi kecepatan dan kondisi jalan yang berbeda. Perlambatan kendaraan dengan sistem ABS juga lebih baik daripada sistem pengereman LBS. Pada perilaku belok kendaraan, koefisien gesek lateral LBS adalah 0.00. Sedangkan pada kecepatan 20 km/jam dengan jalan datar dan menurun, nilai koefisien gesek lateral ABS berkisar antara 0.1-0.45 dan 0.1-0.4. Pada kecepatan 40 km/jam dengan jalan datar dan menurun, nilai koefisien gesek lateral ABS berkisar antara 0.1-0.5 dan 0.1-0.43. Dengan demikian, perilaku belok kendaraan dengan LBS cenderung mengalami oversteer, sedangkan ABS memberikan respons yang lebih baik.

Antilock Braking System (ABS) has become a commonly used braking technology. ABS is designed to prevent the wheels of a vehicle from locking up during braking, as locked wheels can disrupt the balance and stability of the vehicle, potentially leading to accidents. The performance of ABS is not only focused on shortening the braking distance but also on maintaining the balance and stability of the vehicle. This final project will analyze the braking system of the Multipurpose Electric Vehicle ITS (MEvITS). The analysis begins by examining the forces during braking on the vehicle in the form of a free body diagram. Then, the analyzed forces will be formulated into a mathematical model. Subsequently, the mathematical model will be represented in a block diagram in Simulink. The next step involves conducting simulations of the ABS and LBS models with two different speeds. The first simulation is performed at speeds of 20 km/h and 40 km/h, considering both flat and downhill road conditions. The simulation results include the braking time response, stopping distance, deceleration, and the turning behavior of the vehicle. From the conducted analysis, it is found that the ABS braking system has a shorter stopping distance compared to the LBS braking system at various speeds and road conditions. Additionally, the required braking time for ABS is also shorter than LBS under different speed and road condition variations. The deceleration of the vehicle with ABS is also superior to the LBS braking system. In terms of the turning behavior of the vehicle, the lateral friction coefficient for LBS is 0.00. Meanwhile, at a speed of 20 km/h on flat and downhill roads, the lateral friction coefficient for ABS ranges from 0.1 to 0.45 and 0.1 to 0.4. At a speed of 40 km/h on flat and downhill roads, the lateral friction coefficient for ABS ranges from 0.1 to 0.5 and 0.1 to 0.43. Thus, the turning behavior of the vehicle tends to experience oversteer with LBS, while ABS provides better responsiveness.
