Research and assessment of the fuel economy of car using a 5 speed automatic transmission with hydraulic various

Abstract

     This article uses MATLAB – SIMULINK software to reserch and evaluate the fuel economy of cars through the vehicle is dynamics system for vehicle using hydrome chanical systems, the calarlated parameters are equivalent to travel car 2.0 liter. The results of the research will seve as the basic of the calarlation, design, testing and comparision of the powertrain system, ensuring the economic and technical requirements, contributing to the exploitation and use of the powertrain, fuel economy of car equipped with atomatic transmission and hydraulic torque converter achieve the highest efficiency and it’s also an information channel for drivers to operate cars so that they can still ensure the desired dynamics and seve fuel
