Abstract :
The fuel consumption that a vehicle achieves is a function of its conversion efficiency between potential chemical energy, mechanical and electrical energy. By maximizing the global energy conversion efficiency of the entire vehicle, fuel consumption will be minimized. This could be done by minimizing system losses. In this paper, the losses in a drivetrain are analyzed, and it is concluded that the largest share comes from the combustion engine. An algorithm is then introduced that minimizes these losses.
