(2) Untuk mengetahui pengaruh Rpm Pada Motor Ganesha Electric Vehicles 1.0 Base Continous Variable Transmision (CVT) dengan memodifikasi Sudut Primary Pulley 13,5° Dan Variasi Berat Roller. Metode Penelitian Eksperimen adalah metode penelitian yang digunakan untuk mendefinisikan eksperimen sebagai suatu cara mencari hubungan sebab akibat. Dalam penelitian ini yang menjadi subjek penelitian adalah sepeda motor Yamaha Nouvo tahun 2002 dan motor listrik DC 130 volt 30 ampere. Data dalam penelitian ini dikumpulkan dengan melakukan uji coba langsung dengan menggunakan tachometer digital untuk mendapatkan rpm tertinggi , setelah data rpm didapat kemudian dimasukan ke rumus untuk mencari torque tertinngi. Jadi hasil dari pengukuran menggunakan tachometer digital dan perhitungan, sudut primary pulley 13,5° dengan variasi berat roller 10/12 gram mendapatkan rpm tertinggi sebesar 5.396 rpm dan torque tertinggi sebesar 4,583 lb-ft pada roller 12 gram. Sedangkan sudut primary pulley standar 14° dengan variasi berat roller 11/12 gram mendapatkan rpm tertinggi sebesar 4.673 rpm dan Torque tertinggi sebesar 4,637 lb-ft pada roller 12 gram. Maka kesimpulannya, semakin tinggi putaran mesin (rpm), torque akan semakin rendah pada saat motor dalam rpm maximal dan tanpa beban.

The energy management strategy has a great influence on the fuel economy of hybrid electric vehicles, and the equivalent consumption minimization strategy (ECMS) has proved to be a useful tool for the real-time optimal control of Hybrid Electric Vehicles (HEVs). However, the adaptation of the equivalent factor poses a major challenge in order to obtain optimal fuel consumption as well as robustness to varying driving cycles. In this paper, an adaptive-ECMS based on driving pattern recognition (DPR) is established for hybrid electric vehicles with continuously variable transmission. The learning vector quantization (LVQ) neural network model was adopted for the on-line DPR algorithm. The influence of the battery state of charge (SOC) on the optimal equivalent factor was studied under different driving patterns. On this basis, a method of adaptation of the equivalent factor was proposed by considering the type of driving pattern and the battery SOC. Besides that, in order to enhance drivability, penalty terms were introduced to constrain frequent engine on/off events and large variations of the continuously variable transmission (CVT) speed ratio. Simulation results showed that the proposed method efficiently improved the equivalent fuel consumption with charge-sustaining operations and also took into account driving comfort.

Hybrid Electric

Electric and hybrid vehicles are emerging rapidly in the automotive market as alternatives to the traditional Internal Combustion Engine (ICE) driven vehicles to meet stringent emission standards, environmental and energy concerns. Recently, Electric Vehicles (EVs) and Hybrid Electric Vehicles (HEVs) have been introduced in many countries including India. One configuration of a HEV is the Series Hybrid Electric Vehicle (SHEV). The design and analysis of the drive system of a SHEV under Indian conditions is the focus of this paper. In conventional vehicles, the ICE is the power source that drives the vehicle. The energy from the ICE is distributed to the wheels through the transmission, which is then used to generate the traction force at the tyre-road interface. In a HEV, both the engine and the electric motor provide the energy to drive the vehicle. In a SHEV, the energy generated by the electric motor is transmitted through the transmission to meet the torque demand at the wheels. Based on the driver’s acceleration demand and the state of charge of the battery, the controller manages the ICE, the generator and the battery to supply the required energy to the motor. The motor finally develops the required drive torque to generate the traction force at the wheels to meet the vehicle drive performance requirements like gradeability, acceleration and maximum speed. The objective of this paper is to discuss the design of the drive system of a SHEV. This involves the calculation of the power specifications of the electric motor based on the vehicle drive performance requirements. The equations for performing these calculations are presented. The procedure is then demonstrated by considering a typical Indian commercial vehicle along with its typical vehicle parameter values. A simulation study has also been performed by considering the Indian drive cycle to demonstrate the energy savings obtained by the use of a SHEV.

In this paper, a review of the state-of-the-art of various CVT powertrain systems now used or being planned for future use in HEVs is presented. These CVT powertrain systems are classified into three main categories: mechanical CVT, electromechanical CVT (ECVT) and pure electrical CVT (EVT). The research development, system architecture, operation characteristics and the merits and drawbacks of each type are discussed.
