Energy management in an automotive electric/heat engine hybrid powertrain using fuzzy decision making

The authors describe how vehicle emissions legislation has caused interest in the heat engine electric hybrid vehicle to be renewed. The form of such a vehicle and the associated problem of the control of its powertrain are described. A controller for managing the powertrain which uses fuzzy logic to implement decision making is developed. Details are given of simulation experiments carried out in which the controller is used with a validated vehicle model. The results of these simulations are given. Areas of further work are suggested
