This paper deals with the development of force splitting strategies to be used within the computation of the force reference in multi-drive electric powertrains. Under normal operating conditions the total force is divided between the drives according to a desired behavior for better performance or energy consumption. The proposed algorithms take into account possible malfunctions which may reduce the tractive force of one or more drives, thus affecting the output sharing principle. For a number of degraded working conditions, several correction strategies have been implemented, with the aim of minimizing the impact of drive anomalies on the vehicle's behavior and the driver's feeling.

Abstract
This paper deals with the development of force splitting strategies to be used within the computation of the force reference in multi-drive electric powertrains. Under normal operating conditions the total force is divided between the drives according to a desired behavior for better performance or energy consumption. The proposed algorithms take into account possible malfunctions which may reduce the tractive force of one or more drives, thus affecting the output sharing principle. For a number of degraded working conditions, several correction strategies have been implemented, with the aim of minimizing the impact of drive anomalies on the vehicle's behavior and the driver's feeling.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
