Multi-objective Optimization of Hybrid Electric Vehicle Equipped with Power-split Continuously Variable Transmission

This paper aims to find the efficient state of hybrid electric vehicle (HEV) by simultaneous optimization of the control strategy and the power train. The power transmission employed in this vehicle is a power-split continuously variable transmission (CVT) which uses several fixed ratio mechanisms. After describing this transmission, the rules of electric assist control strategy are introduced....

Design of Continuously Variable Transmission (CVT) with Metal Pushing Belt and Variable Pulleys

Nowadays, automakers have invested in new technologies in order to improve the efficiency of their products. Giant automakers have taken an important step toward achieving this objective by designing continuously variable transmission systems (CVT) to continuously adapt the power of the engine with the external load according to the optimum efficiency curve of e...

Theoretical and Experimental Efficiency Analysis of Multi-Degrees-of-Freedom Epicyclic Gear Trains

Abstract. Mechanical efficiency analysis is a fundamental phase in the design of Power Gear Trains (PGTs) transmissions. This paper presents a methodology for computing the mechanical efficiency of Epicyclic Gear Trains (EGTs). A novel feature of this methodology is the capability to take into account load dependent power losses and inertia effects. Finally, the paper describes an apparatus use...

Application of Multi-objective Optimization for Optimization of Half-toroidal Continuously Variable Transmission

Among different goals defined in vehicle design process, fuel consumption (FC) is one of the most important objectives, which significantly has taken into account lately, both by the customers and vehicle manufacturers. One of the significant parameters which impacts the vehicle FC is the efficiency of vehicle's power train. In this paper, a half-toroidal continuously variable transmission (CVT...
