Abstract
A hybrid electrical propulsion system, which comprises a mechanical load; a thermal engine; an electrical machine; a power transmission device comprising a first coupling device connected via a first connecting shaft to the thermal engine and via a second connecting shaft to a second coupling device; and a control system comprising a control logic to provide a setpoint command to the electrical machine. The first coupling device couples the first connecting shaft with the second connecting shaft in a driving manner if a first speed-dependent driving condition is fulfilled. The second coupling device couples a third connecting shaft with a drive shaft in a driving manner if the control logic provides the setpoint command for operating the electrical machine in motor mode and a second speed-dependent driving condition is fulfilled.
