Abstract

Kendaraan listrik hybrid (hybrid electric vehicle) adalah jenis kendaraan hybrid yang menggabungkan sistem mesin pembakaran internal konvensional dengan sistem propulsi listrik. Kehadiran powertrain listrik bertujuan untuk mencapai efisiensi bahan bakar yang lebih baik daripada kendaraan konvensional. Pada sistem hybrid, energi kinetik yang keluar dari kendaraan ditangkap dan disimpan guna mengurangi kebutuhan energi kendaraan untuk bergerak dan meningkatkan efisiensi. Energi tersebut mengurangi kerugian energi yang diakibatkan oleh gaya-gaya yang bekerja saat kendaraan bergerak. Untuk mendapatkan kinerja pengereman yang lebih optimal, pengereman regeneratif dan brake-by-wire digunakan dengan menggantikan sistem pengereman konvensional. Meskipun penelitian regenerative brake-by-wire system sudah mulai banyak dilakukan pada kendaraan, pengembangan teknologi tersebut masih belum banyak diaplikasikan pada sepeda motor hybrid. Oleh karena itu, penelitian dilakukan pada sepeda motor.
Penelitian regenerative brake-by-wire system terbagi dalam dua tahapan utama, yaitu tahap perhitungan dan tahap analisis terhadap besar gaya dan porsi, kontribusi dan efisisensi sistem rem regenerative brake-by-wire system. Dalam tahap perhitungan, dilakukan perhitungan gaya hambat yang bekerja pada kendaraan saat bergerak, perhitungan daya, dan besar energi pengereman yang bisa ditangkap berdasarkan driving cycle WMTC kelas 1 dan WMTC kelas 2. Selanjutnya untuk tahap analisis akan dilakukan analisis terhadap hasil yang didapatkan pada tahap perhitungan sebelumnya.
Dari penelitian ini didapatkan porsi dan gaya pengereman regenerative brake-by-wire bekerja secara penuh tanpa adanya bantuan dari rem mekanis pada variasi j/g 0 sampai 0,5 dengan nilai gaya pengereman aktual terbesar adalah sebesar 1002,71N. Besar kontribusi sistem rem regenerative brake-by-wire terhadap kebutuhan daya kendaraan pada driving cycle WMTC kelas 1 dan 2 adalah 38,48% dan 33,55%. Besar efisiensi sistem rem regenerative brake-by-wire pada sepeda motor hybrid dengan driving cycle WMTC kelas 1 dan 2 adalah 54,89% dan 54,31%.

A hybrid electric vehicle is a type of hybrid vehicle that combines a conventional internal combustion engine system with an electric propulsion system. The presence of an electric powertrain aims to achieve better fuel efficiency than conventional vehicles. The hybrid electric vehicle combines an internal combustion engine and an electric motor. In a hybrid system, the kinetic energy that comes out of the vehicle is captured and stored in order to reduce the energy requirements of the vehicle to move and increase efficiency. To obtain more optimal braking performance, regenerative and brake-by-wire braking are used in place of conventional braking systems. Although research on regenerative brake-by-wire systems has begun to be developed in motorbikes, the development of this technology has not been widely applied to hybrid ones.
Research on regenerative brake-by-wire system is divided into two main stages, namely the calculation phase and the analysis stage of the force and portion size, contribution and efficiency of the system. In the calculation phase, the drag force acting on the vehicle while moving, the power calculation, and the amount of braking energy that can be captured based on the WMTC class 1 and WMTC class 2 driving cycles are calculated. Furthermore, for the analysis stage, the analysis of the results obtained in the previous calculation stage are carried out.
The research concludes that the regenerative braking force and portion of the brake-by-wire work fully without the help of mechanical brakes in the variation of j/g 0 to 0.5 with the largest actual braking force value of 1002.71N. The contribution of regenerative brake-by-wire brake system to vehicle power requirements on the driving cycle of WMTC Class 1 and 2 is 38,48% and 33,55%. The efficiency of the regenerative brake-by-wire brake system on hybrid motorcycles with the WMTC Class 1 and 2 driving cycle is 54,89% and 54,31%, respectively.
