• Abstract:

  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.
