Patent ID: 8545278

Claim:
A method for operation of a hybrid propulsion system of a marine vessel including at least one electric motor and at least one internal combustion engine as drive units, which individually or jointly drive at least one propulsion unit, the method comprising: controlling as a function of a nominal value and a first determinable operating mode of a plurality of operating modes, via a control device, respective power outputs of the drive units to the at least one propulsion unit, such that a total power output, which is dependent on the nominal value, is emitted to the at least one propulsion unit as a result of the sum of the respective power outputs, wherein the total power output is split between the drive units as a function of the nominal value and of the first operating mode, the total power output and the splitting of the total power output between the drive units are controlled on the basis of at least one of characteristic data and characteristic lines of an assembly of the drive units, the control device is configured to store the at least one of characteristic data and characteristic lines for each of the plurality of operating modes, the control device selects the at least one of characteristic data and characteristic lines relevant for control of the power split for the first operating mode as a function of the first operating mode, and at least one of the total power output and the split in the total power output between the drive units is controlled taking account of limit values for the drive units' rate of change.
