Abstract
An electromechanical power transmission chain comprises an electric machine () mechanically connectable to a combustion engine () and to one or more actuators () to be driven, an energy-storage () for storing electric energy, converter equipment () for driving the electric machine in a torque controlled mode when transferring electric energy between the electric machine and the energy-storage, and a device () for producing a torque reference for the electric machine. The device produces a control value based on electric energy stored by the energy-storage so that the control value is a decreasing function of the stored electric energy, and produces the torque reference based on a difference between the control value and a control signal indicative of torque produced by the combustion engine.
