Abstract: A method for operating a generator set includes: operating the generator set in synchronized manner to a power grid, which includes: synchronizing a generator voltage with a grid voltage; matching a generator voltage frequency and/or a generator voltage phase with a grid frequency and/or a grid voltage phase; operating generator set in synchronization mode to synchronize the generator voltage phase with the grid voltage phase; operating an engine in a phase control mode with adjustment of an engine phase to change the generator voltage phase; transmitting the grid voltage phase to a phase regulator; regulating, by the phase regulator, the engine phase to a phase difference, which is created by a difference between the generator voltage phase and the grid voltage phase; and setting a phase parameter formed as the combustion control variable for torque-forming combustion setting of the engine, to adjust the engine phase subject to the phase difference.

Abstract: A method for controlling an internal combustion engine, wherein a first engine control device generates a control signal to actuate a function of the engine. A switchover device transmits the control signal of the first control device to the engine to actuate the function of the engine. The first control device transmits a sign-of-life signal which indicates functionality of the control device to the switchover device. The first engine control device does not transmit the sign-of-life signal or transmits the signal incorrectly if a fault occurs which endangers proper actuation of the function of the engine by the first engine control device. If the sign-of-life signal of the first engine control device is not or is incorrectly received by the switchover device, the switchover device stops transmitting the control signals of the first engine control device and starts transmitting a control signal generated by a second engine control device to the engine to actuate the function of the engine.

Abstract: A method for redundantly controlling a speed of an internal combustion engine, in particular of a vehicle, which includes a redundantly actuatable actuator for adjusting the speed, the method includes the following steps: detecting a first actual speed and a second actual speed of the internal combustion engine, wherein the actual speeds are detected simultaneously and independently of one another; detecting a first actual position and a second actual position of the actuator, wherein the actual positions are detected simultaneously and independently of one another; determining a plausible actual speed and a plausible actual position in accordance with the detected actual speeds and/or the detected actual positions; and actuating the actuator for adjusting the speed in accordance with the plausible actual speed and the plausible actual position.
