METHOD AND DEVICE FOR STABILIZING THE CHOICE OF OPERATING STATES USING AN ENERGY-BASED STABILIZATION STRATEGY FOR HYBRID TRANSMISSION SYSTEMS

摘要

A method for stabilizing the choice between a plurality of operating range states of an electromechanical transmission configured to transmit torque among an engine, at least one electric machine and a final drive comprises requesting execution of a shift from a first operating range state to a second operating range state. Costs associated with operating the transmission in each of the plurality of operating range states including the first and second operating range states are monitored and an energy difference between the first and second operating range states is determined based on the monitored cost. Switching from the first operating range state to the second operating range state is only carried out when the energy difference reaches an integration threshold value.
