Dynamics of Hybrid Propulsion System with Electric Power Divider 2007-01-2134

The paper deals with dynamics of hybrid propulsion system with electric power divider. The physical laboratory model was chosen as example. Mathematical model for transient phenomena during accelerating period of the hybrid vehicle using electric power divider was developed. The accelerating period is divided into three parts. During the first part from stand condition to very low car velocity is the vehicle driven only by the energy from battery. During the second part the battery is totally off and only the combustion engine drives the vehicle. The engine is controlled by ASR system not to bring the vehicle into slipping by getting over the adhesion. In the third part of accelerating period the combustion engine power and revolutions are controlled to get minimum fuel consumption. The simulation can help to find good strategy of the powertrain control.
