Estimativa de Parâmetros do Conversor de Torque da Transmissão Automática de um Veículo de Passeio

Estimation of Parameters of the Torque Converter of an Automatic Transmission of a Passenger Vehicle

Lopes, Elias Dias Rossi; Pinto, André Flora Alves; Reis, Caio Cesar do Prado Dorea;

Artigo:

The automatic transmission has been becoming more usual in the modern vehicles, even those considered low cost ones. The torque converter is the device responsible for the coupling between the engine and the gearbox in automatic transmission vehicles. In this context, this research aims the simulation and estimation of parameters of the automatic transmission of a passenger vehicle. In that purpose, it is implemented the Particle Swarm Optimization Method, which assists in obtaining parameters of the torque converter’s curve from the engine full-load curve and the car real traction diagram. The torque converter’s curves have fundamental importance, and only manufacturers have possession of that information. Beyond that, through those curves, it is possible: to raise the profit of the company, to develop an automobile that is economic in terms of fuel consumption and offers a better adaptation of the engine characteristic curve to the ideal traction curve.
